    Archaeorhizomycetes: unearthing an ancient class of ubiquitous soil fungi (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-08-13
    Beschreibung: Estimates suggest that only one-tenth of the true fungal diversity has been described. Among numerous fungal lineages known only from environmental DNA sequences, Soil Clone Group 1 is the most ubiquitous. These globally distributed fungi may dominate below-ground fungal communities, but their placement in the fungal tree of life has been uncertain. Here, we report cultures of this group and describe the class, Archaeorhizomycetes, phylogenetically placed within subphylum Taphrinomycotina in the Ascomycota. Archaeorhizomycetes comprises hundreds of cryptically reproducing filamentous species that do not form recognizable mycorrhizal structures and have saprotrophic potential, yet are omnipresent in roots and rhizosphere soil and show ecosystem and host root habitat specificity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosling, Anna -- Cox, Filipa -- Cruz-Martinez, Karelyn -- Ihrmark, Katarina -- Grelet, Gwen-Aelle -- Lindahl, Bjorn D -- Menkis, Audrius -- James, Timothy Y -- New York, N.Y. -- Science. 2011 Aug 12;333(6044):876-9. doi: 10.1126/science.1206958.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Forest Mycology and Pathology, Uppsala BioCentre, SLU, Box 7026, 750 07 Uppsala, Sweden. anna.rosling@slu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21836015" target="_blank"〉PubMed〈/a〉

    Early warnings of regime shifts: a whole-ecosystem experiment (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-04-30
    Beschreibung: Catastrophic ecological regime shifts may be announced in advance by statistical early warning signals such as slowing return rates from perturbation and rising variance. The theoretical background for these indicators is rich, but real-world tests are rare, especially for whole ecosystems. We tested the hypothesis that these statistics would be early warning signals for an experimentally induced regime shift in an aquatic food web. We gradually added top predators to a lake over 3 years to destabilize its food web. An adjacent lake was monitored simultaneously as a reference ecosystem. Warning signals of a regime shift were evident in the manipulated lake during reorganization of the food web more than a year before the food web transition was complete, corroborating theory for leading indicators of ecological regime shifts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carpenter, S R -- Cole, J J -- Pace, M L -- Batt, R -- Brock, W A -- Cline, T -- Coloso, J -- Hodgson, J R -- Kitchell, J F -- Seekell, D A -- Smith, L -- Weidel, B -- New York, N.Y. -- Science. 2011 May 27;332(6033):1079-82. doi: 10.1126/science.1203672.

    Comment on "Drought-induced reduction in global terrestrial net primary production from 2000 through 2009" (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-08-27
    Beschreibung: Zhao and Running (Reports, 20 August 2010, p. 940) reported a reduction in global terrestrial net primary production (NPP) from 2000 through 2009. We argue that the small trends, regional patterns, and interannual variations that they describe are artifacts of their NPP model. Satellite observations of vegetation activity show no statistically significant changes in more than 85% of the vegetated lands south of 70 degrees N during the same 2000 to 2009 period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Samanta, Arindam -- Costa, Marcos H -- Nunes, Edson L -- Vieira, Simone A -- Xu, Liang -- Myneni, Ranga B -- New York, N.Y. -- Science. 2011 Aug 26;333(6046):1093; author reply 1093. doi: 10.1126/science.1199048.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geography and Environment, Boston University, Boston, MA 02215, USA. arindam.sam@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21868655" target="_blank"〉PubMed〈/a〉

    Projecting coral reef futures under global warming and ocean acidification (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-07-23
    Beschreibung: Many physiological responses in present-day coral reefs to climate change are interpreted as consistent with the imminent disappearance of modern reefs globally because of annual mass bleaching events, carbonate dissolution, and insufficient time for substantial evolutionary responses. Emerging evidence for variability in the coral calcification response to acidification, geographical variation in bleaching susceptibility and recovery, responses to past climate change, and potential rates of adaptation to rapid warming supports an alternative scenario in which reef degradation occurs with greater temporal and spatial heterogeneity than current projections suggest. Reducing uncertainty in projecting coral reef futures requires improved understanding of past responses to rapid climate change; physiological responses to interacting factors, such as temperature, acidification, and nutrients; and the costs and constraints imposed by acclimation and adaptation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pandolfi, John M -- Connolly, Sean R -- Marshall, Dustin J -- Cohen, Anne L -- New York, N.Y. -- Science. 2011 Jul 22;333(6041):418-22. doi: 10.1126/science.1204794.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Australian Research Council (ARC) Centre of Excellence for Coral Reef Studies, St. Lucia, Queensland 4072, Australia. j.pandolfi@uq.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21778392" target="_blank"〉PubMed〈/a〉

    Cascading effects of bird functional extinction reduce pollination and plant density (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-02-05
    Beschreibung: Reductions in bird numbers could hamper ecosystem services such as pollination, but experimental proof is lacking. We show that functional extinction of bird pollinators has reduced pollination, seed production, and plant density in the shrub Rhabdothamnus solandri (Gesneriaceae) on the North Island ("mainland") of New Zealand but not on three nearby island bird sanctuaries where birds remain abundant. Pollen limitation of fruit set is strong [pollen limitation index (PLI) = 0.69] and significant on the mainland but small (PLI = 0.15) and nonsignificant on islands. Seed production per flower on the mainland is reduced 84%. Mainland sites have similar adult densities, but 55% fewer juvenile plants per adult, than island sites. Seed addition experiments near adult R. solandri plants on the mainland found strong seed limitation 5 years after sowing for R. solandri but not for two other co-occurring woody species. This demonstrates a terrestrial trophic cascade.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, Sandra H -- Kelly, Dave -- Ladley, Jenny J -- Molloy, Sue -- Terry, Jon -- New York, N.Y. -- Science. 2011 Feb 25;331(6020):1068-71. doi: 10.1126/science.1199092.

    African wild ungulates compete with or facilitate cattle depending on season (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-09-24
    Beschreibung: Savannas worldwide are vital for both socioeconomic and biodiversity values. In these ecosystems, management decisions are based on the perception that wildlife and livestock compete for food, yet there are virtually no experimental data to support this assumption. We examined the effects of wild African ungulates on cattle performance, food intake, and diet quality. Wild ungulates depressed cattle food intake and performance during the dry season (competition) but enhanced cattle diet quality and performance during the wet season (facilitation). These results extend our understanding of the context-dependent-competition-facilitation balance, in general, and are critical for better understanding and managing wildlife-livestock coexistence in human-occupied savanna landscapes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Odadi, Wilfred O -- Karachi, Moses K -- Abdulrazak, Shaukat A -- Young, Truman P -- New York, N.Y. -- Science. 2011 Sep 23;333(6050):1753-5. doi: 10.1126/science.1208468.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mpala Research Centre, Post Office Box 555, Nanyuki 10400, Kenya. woodadi@yahoo.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21940896" target="_blank"〉PubMed〈/a〉

    Beschreibung: Using a regionally calibrated model, Sinervo et al.

    Freshwater methane emissions offset the continental carbon sink (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-01-08
    Beschreibung: Inland waters (lakes, reservoirs, streams, and rivers) are often substantial methane (CH(4)) sources in the terrestrial landscape. They are, however, not yet well integrated in global greenhouse gas (GHG) budgets. Data from 474 freshwater ecosystems and the most recent global water area estimates indicate that freshwaters emit at least 103 teragrams of CH(4) year(-1), corresponding to 0.65 petagrams of C as carbon dioxide (CO(2)) equivalents year(-1), offsetting 25% of the estimated land carbon sink. Thus, the continental GHG sink may be considerably overestimated, and freshwaters need to be recognized as important in the global carbon cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bastviken, David -- Tranvik, Lars J -- Downing, John A -- Crill, Patrick M -- Enrich-Prast, Alex -- New York, N.Y. -- Science. 2011 Jan 7;331(6013):50. doi: 10.1126/science.1196808.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Thematic Studies-Water and Environmental Studies, Linkoping University, SE-58183 Linkoping, Sweden. david.bastviken@liu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21212349" target="_blank"〉PubMed〈/a〉

    7000 years of Emiliania huxleyi viruses in the Black Sea (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-07-23
    Beschreibung: A 7000-year record of Coccolithovirus and its host, the calcifying haptophyte Emiliania huxleyi, was reconstructed on the basis of genetic signatures preserved in sediments underlying the Black Sea. The data show that the same virus and host populations can persist for centuries. Major changes in virus and host populations occurred during early sapropel deposition, ~5600 years ago, and throughout the formation of the coccolith-bearing sediments of Unit I during the past 2500 years, when the Black Sea experienced dramatic changes in hydrologic and nutrient regimes. Unit I saw a reoccurrence of the same host genotype thousands of years later in the presence of a different subset of viruses. Historical plankton virus populations can thus be included in paleoecological and paleoenvironmental studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coolen, Marco J L -- New York, N.Y. -- Science. 2011 Jul 22;333(6041):451-2. doi: 10.1126/science.1200072.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marine Chemistry and Geochemistry Department, Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA. mcoolen@whoi.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21778399" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 2011-04-09
    Beschreibung: Erba et al. (Reports, 23 July 2010, p. 428) attributed calcareous nannofossil morphology and assemblage changes across Cretaceous Oceanic Anoxic Event 1a to the effects of surface ocean acidification. We argue that the quality of carbonate preservation in these sequences, the unsupported assumptions of the biotic response to acidity, and the absence of independent proxy estimates for ocean pH or atmospheric pCO(2) render this conclusion questionable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibbs, Samantha J -- Robinson, Stuart A -- Bown, Paul R -- Jones, Tom Dunkley -- Henderiks, Jorijntje -- New York, N.Y. -- Science. 2011 Apr 8;332(6026):175; author reply 175. doi: 10.1126/science.1199459.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Ocean and Earth Sciences, National Oceanography Centre, Southampton, European Way, Southampton, SO14 3ZH, UK. sxg@noc.soton.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21474738" target="_blank"〉PubMed〈/a〉

    A large and persistent carbon sink in the world's forests (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-07-19
    Beschreibung: The terrestrial carbon sink has been large in recent decades, but its size and location remain uncertain. Using forest inventory data and long-term ecosystem carbon studies, we estimate a total forest sink of 2.4 +/- 0.4 petagrams of carbon per year (Pg C year(-1)) globally for 1990 to 2007. We also estimate a source of 1.3 +/- 0.7 Pg C year(-1) from tropical land-use change, consisting of a gross tropical deforestation emission of 2.9 +/- 0.5 Pg C year(-1) partially compensated by a carbon sink in tropical forest regrowth of 1.6 +/- 0.5 Pg C year(-1). Together, the fluxes comprise a net global forest sink of 1.1 +/- 0.8 Pg C year(-1), with tropical estimates having the largest uncertainties. Our total forest sink estimate is equivalent in magnitude to the terrestrial sink deduced from fossil fuel emissions and land-use change sources minus ocean and atmospheric sinks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, Yude -- Birdsey, Richard A -- Fang, Jingyun -- Houghton, Richard -- Kauppi, Pekka E -- Kurz, Werner A -- Phillips, Oliver L -- Shvidenko, Anatoly -- Lewis, Simon L -- Canadell, Josep G -- Ciais, Philippe -- Jackson, Robert B -- Pacala, Stephen W -- McGuire, A David -- Piao, Shilong -- Rautiainen, Aapo -- Sitch, Stephen -- Hayes, Daniel -- New York, N.Y. -- Science. 2011 Aug 19;333(6045):988-93. doi: 10.1126/science.1201609.

    Calibrating the end-Permian mass extinction (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-11-19
    Beschreibung: The end-Permian mass extinction was the most severe biodiversity crisis in Earth history. To better constrain the timing, and ultimately the causes of this event, we collected a suite of geochronologic, isotopic, and biostratigraphic data on several well-preserved sedimentary sections in South China. High-precision U-Pb dating reveals that the extinction peak occurred just before 252.28 +/- 0.08 million years ago, after a decline of 2 per mil ( per thousand) in delta(13)C over 90,000 years, and coincided with a delta(13)C excursion of -5 per thousand that is estimated to have lasted 〈/=20,000 years. The extinction interval was less than 200,000 years and synchronous in marine and terrestrial realms; associated charcoal-rich and soot-bearing layers indicate widespread wildfires on land. A massive release of thermogenic carbon dioxide and/or methane may have caused the catastrophic extinction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, Shu-zhong -- Crowley, James L -- Wang, Yue -- Bowring, Samuel A -- Erwin, Douglas H -- Sadler, Peter M -- Cao, Chang-qun -- Rothman, Daniel H -- Henderson, Charles M -- Ramezani, Jahandar -- Zhang, Hua -- Shen, Yanan -- Wang, Xiang-dong -- Wang, Wei -- Mu, Lin -- Li, Wen-zhong -- Tang, Yue-gang -- Liu, Xiao-lei -- Liu, Lu-jun -- Zeng, Yong -- Jiang, Yao-fa -- Jin, Yu-gan -- New York, N.Y. -- Science. 2011 Dec 9;334(6061):1367-72. doi: 10.1126/science.1213454.

    Changes in climatic water balance drive downhill shifts in plant species' optimum elevations (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-01-22
    Beschreibung: Uphill shifts of species' distributions in response to historical warming are well documented, which leads to widespread expectations of continued uphill shifts under future warming. Conversely, downhill shifts are often considered anomalous and unrelated to climate change. By comparing the altitudinal distributions of 64 plant species between the 1930s and the present day within California, we show that climate changes have resulted in a significant downward shift in species' optimum elevations. This downhill shift is counter to what would be expected given 20th-century warming but is readily explained by species' niche tracking of regional changes in climatic water balance rather than temperature. Similar downhill shifts can be expected to occur where future climate change scenarios project increases in water availability that outpace evaporative demand.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crimmins, Shawn M -- Dobrowski, Solomon Z -- Greenberg, Jonathan A -- Abatzoglou, John T -- Mynsberge, Alison R -- New York, N.Y. -- Science. 2011 Jan 21;331(6015):324-7. doi: 10.1126/science.1199040.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Forest Management, College of Forestry and Conservation, University of Montana, Missoula, MT 59812, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21252344" target="_blank"〉PubMed〈/a〉

    A common scaling rule for abundance, energetics, and production of parasitic and free-living species (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-07-23
    Beschreibung: The metabolic theory of ecology uses the scaling of metabolism with body size and temperature to explain the causes and consequences of species abundance. However, the theory and its empirical tests have never simultaneously examined parasites alongside free-living species. This is unfortunate because parasites represent at least half of species diversity. We show that metabolic scaling theory could not account for the abundance of parasitic or free-living species in three estuarine food webs until accounting for trophic dynamics. Analyses then revealed that the abundance of all species uniformly scaled with body mass to the -¾ power. This result indicates "production equivalence," where biomass production within trophic levels is invariant of body size across all species and functional groups: invertebrate or vertebrate, ectothermic or endothermic, and free-living or parasitic.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3236646/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3236646/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hechinger, Ryan F -- Lafferty, Kevin D -- Dobson, Andy P -- Brown, James H -- Kuris, Armand M -- P20 RR018754/RR/NCRR NIH HHS/ -- P20 RR018754-07/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2011 Jul 22;333(6041):445-8. doi: 10.1126/science.1204337.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marine Science Institute and Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA 93106, USA. hechinger@lifesci.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21778398" target="_blank"〉PubMed〈/a〉

    The global extent and determinants of savanna and forest as alternative biome states (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-10-15
    Beschreibung: Theoretically, fire-tree cover feedbacks can maintain savanna and forest as alternative stable states. However, the global extent of fire-driven discontinuities in tree cover is unknown, especially accounting for seasonality and soils. We use tree cover, climate, fire, and soils data sets to show that tree cover is globally discontinuous. Climate influences tree cover globally but, at intermediate rainfall (1000 to 2500 millimeters) with mild seasonality (less than 7 months), tree cover is bimodal, and only fire differentiates between savanna and forest. These may be alternative states over large areas, including parts of Amazonia and the Congo. Changes in biome distributions, whether at the cost of savanna (due to fragmentation) or forest (due to climate), will be neither smooth nor easily reversible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Staver, A Carla -- Archibald, Sally -- Levin, Simon A -- New York, N.Y. -- Science. 2011 Oct 14;334(6053):230-2. doi: 10.1126/science.1210465.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA. astaver@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21998389" target="_blank"〉PubMed〈/a〉

    Beschreibung: Crimmins et al. (Reports, 21 January 2011, p. 324) attributed an apparent downward elevational shift of California plant species to a precipitation-induced decline in climatic water deficit. We show that the authors miscalculated deficit, that the apparent decline in species' elevations is likely a consequence of geographic biases, and that unlike temperature changes, precipitation changes should not be expected to cause coordinated directional shifts in species' elevations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephenson, Nathan L -- Das, Adrian J -- New York, N.Y. -- Science. 2011 Oct 14;334(6053):177; author reply 177. doi: 10.1126/science.1205740.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉US Geological Survey, Western Ecological Research Center, Three Rivers, CA 93271, USA. nstephenson@usgs.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21998371" target="_blank"〉PubMed〈/a〉

    Impacts of fishing low-trophic level species on marine ecosystems (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-07-23
    Beschreibung: Low-trophic level species account for more than 30% of global fisheries production and contribute substantially to global food security. We used a range of ecosystem models to explore the effects of fishing low-trophic level species on marine ecosystems, including marine mammals and seabirds, and on other commercially important species. In five well-studied ecosystems, we found that fishing these species at conventional maximum sustainable yield (MSY) levels can have large impacts on other parts of the ecosystem, particularly when they constitute a high proportion of the biomass in the ecosystem or are highly connected in the food web. Halving exploitation rates would result in much lower impacts on marine ecosystems while still achieving 80% of MSY.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Anthony D M -- Brown, Christopher J -- Bulman, Catherine M -- Fulton, Elizabeth A -- Johnson, Penny -- Kaplan, Isaac C -- Lozano-Montes, Hector -- Mackinson, Steven -- Marzloff, Martin -- Shannon, Lynne J -- Shin, Yunne-Jai -- Tam, Jorge -- New York, N.Y. -- Science. 2011 Aug 26;333(6046):1147-50. doi: 10.1126/science.1209395.

    Baseline map of carbon emissions from deforestation in tropical regions (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-06-23
    Beschreibung: Policies to reduce emissions from deforestation would benefit from clearly derived, spatially explicit, statistically bounded estimates of carbon emissions. Existing efforts derive carbon impacts of land-use change using broad assumptions, unreliable data, or both. We improve on this approach using satellite observations of gross forest cover loss and a map of forest carbon stocks to estimate gross carbon emissions across tropical regions between 2000 and 2005 as 0.81 petagram of carbon per year, with a 90% prediction interval of 0.57 to 1.22 petagrams of carbon per year. This estimate is 25 to 50% of recently published estimates. By systematically matching areas of forest loss with their carbon stocks before clearing, these results serve as a more accurate benchmark for monitoring global progress on reducing emissions from deforestation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harris, Nancy L -- Brown, Sandra -- Hagen, Stephen C -- Saatchi, Sassan S -- Petrova, Silvia -- Salas, William -- Hansen, Matthew C -- Potapov, Peter V -- Lotsch, Alexander -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1573-6. doi: 10.1126/science.1217962.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecosystem Services Unit, Winrock International, Arlington, VA 22202, USA. nharris@winrock.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22723420" target="_blank"〉PubMed〈/a〉

    Comment on "Global resilience of tropical forest and savanna to critical transitions" (2012)

    Details
    Publikationsdatum: 2012-05-05
    Beschreibung: Hirota et al. (Reports, 14 October 2011, p. 232) used spatial data to show that grasslands, savannas, and forests represent opposing stable states. Reanalyzing their data and drawing from temporal studies, we argue that spatial analyses underestimate the bistability of grasslands and savannas due to limitations of substituting space for time. We propose that temporal and spatial data are needed to predict critical transitions between grasslands and savannas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ratajczak, Zak -- Nippert, Jesse B -- New York, N.Y. -- Science. 2012 May 4;336(6081):541; author reply 541. doi: 10.1126/science.1219346.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, Kansas State University, 116 Ackert Hall, Manhattan, KS 66506, USA. zarata@ksu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22556235" target="_blank"〉PubMed〈/a〉

    Detecting causality in complex ecosystems (2012)

    Details
    Publikationsdatum: 2012-09-22
    Beschreibung: Identifying causal networks is important for effective policy and management recommendations on climate, epidemiology, financial regulation, and much else. We introduce a method, based on nonlinear state space reconstruction, that can distinguish causality from correlation. It extends to nonseparable weakly connected dynamic systems (cases not covered by the current Granger causality paradigm). The approach is illustrated both by simple models (where, in contrast to the real world, we know the underlying equations/relations and so can check the validity of our method) and by application to real ecological systems, including the controversial sardine-anchovy-temperature problem.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sugihara, George -- May, Robert -- Ye, Hao -- Hsieh, Chih-hao -- Deyle, Ethan -- Fogarty, Michael -- Munch, Stephan -- New York, N.Y. -- Science. 2012 Oct 26;338(6106):496-500. doi: 10.1126/science.1227079.

    Impacts of biodiversity loss escalate through time as redundancy fades (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-05-05
    Beschreibung: Plant diversity generally promotes biomass production, but how the shape of the response curve changes with time remains unclear. This is a critical knowledge gap because the shape of this relationship indicates the extent to which loss of the first few species will influence biomass production. Using two long-term (〉/=13 years) biodiversity experiments, we show that the effects of diversity on biomass productivity increased and became less saturating over time. Our analyses suggest that effects of diversity-dependent ecosystem feedbacks and interspecific complementarity accumulate over time, causing high-diversity species combinations that appeared functionally redundant during early years to become more functionally unique through time. Consequently, simplification of diverse ecosystems will likely have greater negative impacts on ecosystem functioning than has been suggested by short-term experiments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reich, Peter B -- Tilman, David -- Isbell, Forest -- Mueller, Kevin -- Hobbie, Sarah E -- Flynn, Dan F B -- Eisenhauer, Nico -- New York, N.Y. -- Science. 2012 May 4;336(6081):589-92. doi: 10.1126/science.1217909.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Forest Resources, University of Minnesota, St. Paul, MN 55108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22556253" target="_blank"〉PubMed〈/a〉

    Global correlations in tropical tree species richness and abundance reject neutrality (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-01-28
    Beschreibung: Patterns of species richness and relative abundance at some scales cannot be distinguished from predictions of null models, including zero-sum neutral models of population change and random speciation-extinction models of evolutionary diversification. Both models predict that species richness or population abundance produced by independent iterations of the same processes in different regions should be uncorrelated. We find instead that the number of species and individuals in families of trees in forest plots are strongly correlated across Southeast Asia, Africa, and tropical America. These correlations imply that deterministic processes influenced by evolutionarily conservative family-level traits constrain the number of confamilial tree species and individuals that can be supported in regional species pools and local assemblages in humid tropical forests.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ricklefs, Robert E -- Renner, Susanne S -- New York, N.Y. -- Science. 2012 Jan 27;335(6067):464-7. doi: 10.1126/science.1215182.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Missouri-St. Louis, MO 63121-4499, USA. ricklefs@umsl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22282811" target="_blank"〉PubMed〈/a〉

    Substrate-controlled succession of marine bacterioplankton populations induced by a phytoplankton bloom (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-05-05
    Beschreibung: Phytoplankton blooms characterize temperate ocean margin zones in spring. We investigated the bacterioplankton response to a diatom bloom in the North Sea and observed a dynamic succession of populations at genus-level resolution. Taxonomically distinct expressions of carbohydrate-active enzymes (transporters; in particular, TonB-dependent transporters) and phosphate acquisition strategies were found, indicating that distinct populations of Bacteroidetes, Gammaproteobacteria, and Alphaproteobacteria are specialized for successive decomposition of algal-derived organic matter. Our results suggest that algal substrate availability provided a series of ecological niches in which specialized populations could bloom. This reveals how planktonic species, despite their seemingly homogeneous habitat, can evade extinction by direct competition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teeling, Hanno -- Fuchs, Bernhard M -- Becher, Dorte -- Klockow, Christine -- Gardebrecht, Antje -- Bennke, Christin M -- Kassabgy, Mariette -- Huang, Sixing -- Mann, Alexander J -- Waldmann, Jost -- Weber, Marc -- Klindworth, Anna -- Otto, Andreas -- Lange, Jana -- Bernhardt, Jorg -- Reinsch, Christine -- Hecker, Michael -- Peplies, Jorg -- Bockelmann, Frank D -- Callies, Ulrich -- Gerdts, Gunnar -- Wichels, Antje -- Wiltshire, Karen H -- Glockner, Frank Oliver -- Schweder, Thomas -- Amann, Rudolf -- New York, N.Y. -- Science. 2012 May 4;336(6081):608-11. doi: 10.1126/science.1218344.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Marine Microbiology, Celsiusstrasse 1, 28359 Bremen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22556258" target="_blank"〉PubMed〈/a〉

    Ecological context influences epidemic size and parasite-driven evolution (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-03-31
    Beschreibung: The occurrence and magnitude of disease outbreaks can strongly influence host evolution. In particular, when hosts face a resistance-fecundity trade-off, they might evolve increased resistance to infection during larger epidemics but increased susceptibility during smaller ones. We tested this theoretical prediction by using a zooplankton-yeast host-parasite system in which ecological factors determine epidemic size. Lakes with high productivity and low predation pressure had large yeast epidemics; during these outbreaks, hosts became more resistant to infection. However, with low productivity and high predation, epidemics remained small and hosts evolved increased susceptibility. Thus, by modulating disease outbreaks, ecological context (productivity and predation) shaped host evolution during epidemics. Consequently, anthropogenic alteration of productivity and predation might strongly influence both ecological and evolutionary outcomes of disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duffy, Meghan A -- Ochs, Jessica Housley -- Penczykowski, Rachel M -- Civitello, David J -- Klausmeier, Christopher A -- Hall, Spencer R -- New York, N.Y. -- Science. 2012 Mar 30;335(6076):1636-8. doi: 10.1126/science.1215429.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biology, Georgia Institute of Technology, Atlanta, GA 30332-0230, USA. duffy@gatech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22461614" target="_blank"〉PubMed〈/a〉

    The geological record of ocean acidification (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-03-03
    Beschreibung: Ocean acidification may have severe consequences for marine ecosystems; however, assessing its future impact is difficult because laboratory experiments and field observations are limited by their reduced ecologic complexity and sample period, respectively. In contrast, the geological record contains long-term evidence for a variety of global environmental perturbations, including ocean acidification plus their associated biotic responses. We review events exhibiting evidence for elevated atmospheric CO(2), global warming, and ocean acidification over the past ~300 million years of Earth's history, some with contemporaneous extinction or evolutionary turnover among marine calcifiers. Although similarities exist, no past event perfectly parallels future projections in terms of disrupting the balance of ocean carbonate chemistry-a consequence of the unprecedented rapidity of CO(2) release currently taking place.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Honisch, Barbel -- Ridgwell, Andy -- Schmidt, Daniela N -- Thomas, Ellen -- Gibbs, Samantha J -- Sluijs, Appy -- Zeebe, Richard -- Kump, Lee -- Martindale, Rowan C -- Greene, Sarah E -- Kiessling, Wolfgang -- Ries, Justin -- Zachos, James C -- Royer, Dana L -- Barker, Stephen -- Marchitto, Thomas M Jr -- Moyer, Ryan -- Pelejero, Carles -- Ziveri, Patrizia -- Foster, Gavin L -- Williams, Branwen -- New York, N.Y. -- Science. 2012 Mar 2;335(6072):1058-63. doi: 10.1126/science.1208277.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lamont-Doherty Earth Observatory of Columbia University, Palisades, NY 10964, USA. hoenisch@ldeo.columbia.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22383840" target="_blank"〉PubMed〈/a〉

    Untangling genomes from metagenomes: revealing an uncultured class of marine Euryarchaeota (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-02-04
    Beschreibung: Ecosystems are shaped by complex communities of mostly unculturable microbes. Metagenomes provide a fragmented view of such communities, but the ecosystem functions of major groups of organisms remain mysterious. To better characterize members of these communities, we developed methods to reconstruct genomes directly from mate-paired short-read metagenomes. We closed a genome representing the as-yet uncultured marine group II Euryarchaeota, assembled de novo from 1.7% of a metagenome sequenced from surface seawater. The genome describes a motile, photo-heterotrophic cell focused on degradation of protein and lipids and clarifies the origin of proteorhodopsin. It also demonstrates that high-coverage mate-paired sequence can overcome assembly difficulties caused by interstrain variation in complex microbial communities, enabling inference of ecosystem functions for uncultured members.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iverson, Vaughn -- Morris, Robert M -- Frazar, Christian D -- Berthiaume, Chris T -- Morales, Rhonda L -- Armbrust, E Virginia -- New York, N.Y. -- Science. 2012 Feb 3;335(6068):587-90. doi: 10.1126/science.1212665.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Oceanography, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22301318" target="_blank"〉PubMed〈/a〉

    Comment on "Global correlations in tropical tree species richness and abundance reject neutrality" (2012)

    Publikationsdatum: 2012-06-30
    Beschreibung: Ricklefs and Renner (Reports, 27 January 2012, p. 464) suggested that strong correlations in the diversity of shared families between isolated tree assemblages reject neutrality. Simulations of a neutral model indicate, however, that isolated assemblages under various configurations of random speciation and extinction do sustain strong correlations in the diversity of shared families. Thus, reported correlations support rather than reject neutral theory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mora, Camilo -- New York, N.Y. -- Science. 2012 Jun 29;336(6089):1639; author reply 1639. doi: 10.1126/science.1220980.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geography, University of Hawaii, Honolulu, HI 96822, USA. cmora@hawaii.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22745402" target="_blank"〉PubMed〈/a〉

    Aerobic microbial respiration in 86-million-year-old deep-sea red clay (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-05-19
    Beschreibung: Microbial communities can subsist at depth in marine sediments without fresh supply of organic matter for millions of years. At threshold sedimentation rates of 1 millimeter per 1000 years, the low rates of microbial community metabolism in the North Pacific Gyre allow sediments to remain oxygenated tens of meters below the sea floor. We found that the oxygen respiration rates dropped from 10 micromoles of O(2) liter(-1) year(-1) near the sediment-water interface to 0.001 micromoles of O(2) liter(-1) year(-1) at 30-meter depth within 86 million-year-old sediment. The cell-specific respiration rate decreased with depth but stabilized at around 10(-3) femtomoles of O(2) cell(-1) day(-1) 10 meters below the seafloor. This result indicated that the community size is controlled by the rate of carbon oxidation and thereby by the low available energy flux.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roy, Hans -- Kallmeyer, Jens -- Adhikari, Rishi Ram -- Pockalny, Robert -- Jorgensen, Bo Barker -- D'Hondt, Steven -- New York, N.Y. -- Science. 2012 May 18;336(6083):922-5. doi: 10.1126/science.1219424.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Geomicrobiology, Department of Bioscience, Aarhus University, Ny Munkegade 116, 8000 Aarhus C, Denmark. hans.roy@biology.au.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22605778" target="_blank"〉PubMed〈/a〉

    The aftermath of megafaunal extinction: ecosystem transformation in Pleistocene Australia (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-03-24
    Beschreibung: Giant vertebrates dominated many Pleistocene ecosystems. Many were herbivores, and their sudden extinction in prehistory could have had large ecological impacts. We used a high-resolution 130,000-year environmental record to help resolve the cause and reconstruct the ecological consequences of extinction of Australia's megafauna. Our results suggest that human arrival rather than climate caused megafaunal extinction, which then triggered replacement of mixed rainforest by sclerophyll vegetation through a combination of direct effects on vegetation of relaxed herbivore pressure and increased fire in the landscape. This ecosystem shift was as large as any effect of climate change over the last glacial cycle, and indicates the magnitude of changes that may have followed megafaunal extinction elsewhere in the world.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rule, Susan -- Brook, Barry W -- Haberle, Simon G -- Turney, Chris S M -- Kershaw, A Peter -- Johnson, Christopher N -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1483-6. doi: 10.1126/science.1214261.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Culture, History and Language, The Australian National University, Canberra, ACT, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442481" target="_blank"〉PubMed〈/a〉

    Heavy livestock grazing promotes locust outbreaks by lowering plant nitrogen content (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-01-28
    Beschreibung: Current paradigms generally assume that increased plant nitrogen (N) should enhance herbivore performance by relieving protein limitation, increasing herbivorous insect populations. We show, in contrast to this scenario, that host plant N enrichment and high-protein artificial diets decreased the size and viability of Oedaleus asiaticus, a dominant locust of north Asian grasslands. This locust preferred plants with low N content and artificial diets with low protein and high carbohydrate content. Plant N content was lowest and locust abundance highest in heavily livestock-grazed fields where soils were N-depleted, likely due to enhanced erosion. These results suggest that heavy livestock grazing and consequent steppe degradation in the Eurasian grassland promote outbreaks of this locust by reducing plant protein content.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cease, Arianne J -- Elser, James J -- Ford, Colleen F -- Hao, Shuguang -- Kang, Le -- Harrison, Jon F -- New York, N.Y. -- Science. 2012 Jan 27;335(6067):467-9. doi: 10.1126/science.1214433.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Life Sciences, Arizona State University, Tempe, AZ 85287, USA. arianne.cease@asu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22282812" target="_blank"〉PubMed〈/a〉

    Comment on "Global correlations in tropical tree species richness and abundance reject neutrality" (2012)

    Details
    Publikationsdatum: 2012-06-30
    Beschreibung: Ricklefs and Renner (Reports, 27 January 2012, p. 464) found significant correlations for abundances and species diversities of families and orders of trees on different continents, which they suggested falsifies the neutral theory of biodiversity (NTB). We argue that the correlations among families and orders and the lack of correlations among genera can be explained by the NTB.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Anping -- Wang, Shaopeng -- Pacala, Stephen W -- New York, N.Y. -- Science. 2012 Jun 29;336(6089):1639; author reply 1639. doi: 10.1126/science.1222534.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA. anpingc@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22745403" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 2012-03-24
    Beschreibung: Adler et al. (Reports, 23 September 2011, p. 1750) analyzed the standardized sampling data from 48 herbaceous-dominated plant communities and concluded that "Productivity is a poor predictor of plant species richness" at fine-scale. However, their method was biased toward site-number-dominated plant communities. They also failed to provide enough data for regional analysis and detailed information for within-site analysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, Xubin -- Liu, Fengqiao -- Zhang, Mi -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1441; author reply 1441. doi: 10.1126/science.1214786.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Environmental Engineering, Texas A&M University-Kingsville, Kingsville, TX 78363, USA. xubin.hu.pan@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442463" target="_blank"〉PubMed〈/a〉

    Population genomics of early events in the ecological differentiation of bacteria (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-04-12
    Beschreibung: Genetic exchange is common among bacteria, but its effect on population diversity during ecological differentiation remains controversial. A fundamental question is whether advantageous mutations lead to selection of clonal genomes or, as in sexual eukaryotes, sweep through populations on their own. Here, we show that in two recently diverged populations of ocean bacteria, ecological differentiation has occurred akin to a sexual mechanism: A few genome regions have swept through subpopulations in a habitat-specific manner, accompanied by gradual separation of gene pools as evidenced by increased habitat specificity of the most recent recombinations. These findings reconcile previous, seemingly contradictory empirical observations of the genetic structure of bacterial populations and point to a more unified process of differentiation in bacteria and sexual eukaryotes than previously thought.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3337212/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3337212/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shapiro, B Jesse -- Friedman, Jonathan -- Cordero, Otto X -- Preheim, Sarah P -- Timberlake, Sonia C -- Szabo, Gitta -- Polz, Martin F -- Alm, Eric J -- U54 GM088558/GM/NIGMS NIH HHS/ -- U54 GM088558-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Apr 6;336(6077):48-51. doi: 10.1126/science.1218198.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Computational and Systems Biology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22491847" target="_blank"〉PubMed〈/a〉

    Glacial survival of boreal trees in northern Scandinavia (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-03-03
    Beschreibung: It is commonly believed that trees were absent in Scandinavia during the last glaciation and first recolonized the Scandinavian Peninsula with the retreat of its ice sheet some 9000 years ago. Here, we show the presence of a rare mitochondrial DNA haplotype of spruce that appears unique to Scandinavia and with its highest frequency to the west-an area believed to sustain ice-free refugia during most of the last ice age. We further show the survival of DNA from this haplotype in lake sediments and pollen of Trondelag in central Norway dating back ~10,300 years and chloroplast DNA of pine and spruce in lake sediments adjacent to the ice-free Andoya refugium in northwestern Norway as early as ~22,000 and 17,700 years ago, respectively. Our findings imply that conifer trees survived in ice-free refugia of Scandinavia during the last glaciation, challenging current views on survival and spread of trees as a response to climate changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parducci, Laura -- Jorgensen, Tina -- Tollefsrud, Mari Mette -- Elverland, Ellen -- Alm, Torbjorn -- Fontana, Sonia L -- Bennett, K D -- Haile, James -- Matetovici, Irina -- Suyama, Yoshihisa -- Edwards, Mary E -- Andersen, Kenneth -- Rasmussen, Morten -- Boessenkool, Sanne -- Coissac, Eric -- Brochmann, Christian -- Taberlet, Pierre -- Houmark-Nielsen, Michael -- Larsen, Nicolaj Krog -- Orlando, Ludovic -- Gilbert, M Thomas P -- Kjaer, Kurt H -- Alsos, Inger Greve -- Willerslev, Eske -- New York, N.Y. -- Science. 2012 Mar 2;335(6072):1083-6. doi: 10.1126/science.1216043.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Genetics, Evolutionary Biology Centre, Uppsala University, Uppsala, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22383845" target="_blank"〉PubMed〈/a〉

    Beschreibung: In animals and plants, social structure can reduce conflict within populations and bias aggression toward competing populations; however, for bacteria in the wild it remains unknown whether such population-level organization exists. Here, we show that environmental bacteria are organized into socially cohesive units in which antagonism occurs between rather than within ecologically defined populations. By screening approximately 35,000 possible mutual interactions among Vibrionaceae isolates from the ocean, we show that genotypic clusters known to have cohesive habitat association also act as units in terms of antibiotic production and resistance. Genetic analyses show that within populations, broad-range antibiotics are produced by few genotypes, whereas all others are resistant, suggesting cooperation between conspecifics. Natural antibiotics may thus mediate competition between populations rather than solely increase the success of individuals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cordero, Otto X -- Wildschutte, Hans -- Kirkup, Benjamin -- Proehl, Sarah -- Ngo, Lynn -- Hussain, Fatima -- Le Roux, Frederique -- Mincer, Tracy -- Polz, Martin F -- New York, N.Y. -- Science. 2012 Sep 7;337(6099):1228-31. doi: 10.1126/science.1219385.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Civil and Environmental Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22955834" target="_blank"〉PubMed〈/a〉

    Seasonality in ocean microbial communities (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-02-11
    Beschreibung: Ocean warming occurs every year in seasonal cycles that can help us to understand long-term responses of plankton to climate change. Rhythmic seasonal patterns of microbial community turnover are revealed when high-resolution measurements of microbial plankton diversity are applied to samples collected in lengthy time series. Seasonal cycles in microbial plankton are complex, but the expansion of fixed ocean stations monitoring long-term change and the development of automated instrumentation are providing the time-series data needed to understand how these cycles vary across broad geographical scales. By accumulating data and using predictive modeling, we gain insights into changes that will occur as the ocean surface continues to warm and as the extent and duration of ocean stratification increase. These developments will enable marine scientists to predict changes in geochemical cycles mediated by microbial communities and to gauge their broader impacts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giovannoni, Stephen J -- Vergin, Kevin L -- New York, N.Y. -- Science. 2012 Feb 10;335(6069):671-6. doi: 10.1126/science.1198078.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Oregon State University, Corvallis, OR 97331, USA. steve.giovannoni@oregonstate.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22323811" target="_blank"〉PubMed〈/a〉
