    Description: Microbes are incredibly abundant and diverse and are key to ecosystem functioning, yet relatively little is known about the ecological and evolutionary mechanisms that shape their distributions. Bacteriophages, viral parasites that lyse their bacterial hosts, exert intense and spatially varying selection pressures on bacteria and vice versa. We measured local adaptation of bacteria and their associated phages in a centimeter-scale soil population. We first demonstrate that a large proportion of bacteria is sensitive to locally occurring phages. We then show that sympatric phages (isolated from the same 2-gram soil samples as the bacteria) are more infective than are phages from samples some distance away. This study demonstrates the importance of biotic interactions for the small-scale spatial structuring of microbial genetic diversity in soil.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vos, Michiel -- Birkett, Philip J -- Birch, Elizabeth -- Griffiths, Robert I -- Buckling, Angus -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):833. doi: 10.1126/science.1174173.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Oxford, Oxford OX1 3PS, UK. michiel.vos@nioo.knaw.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19679806" target="_blank"〉PubMed〈/a〉

    Description: Ecological speciation occurs when ecologically based, divergent selection causes the evolution of reproductive isolation. There are many empirical examples of this process; however, there exists a poorly characterized stage during which the traits that distinguish species ecologically and reproductively segregate in a single population. By using a combination of genetic mapping, mate-choice experiments, field observations, and population genetics, we studied a butterfly population with a mimetic wing color polymorphism and found that the butterflies exhibited partial, color-based, assortative mate preference. These traits represent the divergent, ecologically based signal and preference components of sexual isolation that usually distinguish incipient and sibling species. The association between behavior and recognition trait in a single population may enhance the probability of speciation and provides an example of the missing link between an interbreeding population and isolated species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875868/" 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/PMC2875868/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamberlain, Nicola L -- Hill, Ryan I -- Kapan, Durrell D -- Gilbert, Lawrence E -- Kronforst, Marcus R -- GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763-06/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):847-50. doi: 10.1126/science.1179141.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Arts and Sciences Center for Systems Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892982" target="_blank"〉PubMed〈/a〉

    Description: Hominid fossils predating the emergence of Australopithecus have been sparse and fragmentary. The evolution of our lineage after the last common ancestor we shared with chimpanzees has therefore remained unclear. Ardipithecus ramidus, recovered in ecologically and temporally resolved contexts in Ethiopia's Afar Rift, now illuminates earlier hominid paleobiology and aspects of extant African ape evolution. More than 110 specimens recovered from 4.4-million-year-old sediments include a partial skeleton with much of the skull, hands, feet, limbs, and pelvis. This hominid combined arboreal palmigrade clambering and careful climbing with a form of terrestrial bipedality more primitive than that of Australopithecus. Ar. ramidus had a reduced canine/premolar complex and a little-derived cranial morphology and consumed a predominantly C3 plant-based diet (plants using the C3 photosynthetic pathway). Its ecological habitat appears to have been largely woodland-focused. Ar. ramidus lacks any characters typical of suspension, vertical climbing, or knuckle-walking. Ar. ramidus indicates that despite the genetic similarities of living humans and chimpanzees, the ancestor we last shared probably differed substantially from any extant African ape. Hominids and extant African apes have each become highly specialized through very different evolutionary pathways. This evidence also illuminates the origins of orthogrady, bipedality, ecology, diet, and social behavior in earliest Hominidae and helps to define the basal hominid adaptation, thereby accentuating the derived nature of Australopithecus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, Tim D -- Asfaw, Berhane -- Beyene, Yonas -- Haile-Selassie, Yohannes -- Lovejoy, C Owen -- Suwa, Gen -- WoldeGabriel, Giday -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):75-86.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Evolution Research Center and Department of Integrative Biology, 3101 Valley Life Sciences Building, University of California, Berkeley, CA 94720, USA. timwhite@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810190" target="_blank"〉PubMed〈/a〉

    Description: Oceanic production of calcium carbonate is conventionally attributed to marine plankton (coccolithophores and foraminifera). Here we report that marine fish produce precipitated carbonates within their intestines and excrete these at high rates. When combined with estimates of global fish biomass, this suggests that marine fish contribute 3 to 15% of total oceanic carbonate production. Fish carbonates have a higher magnesium content and solubility than traditional sources, yielding faster dissolution with depth. This may explain up to a quarter of the increase in titratable alkalinity within 1000 meters of the ocean surface, a controversial phenomenon that has puzzled oceanographers for decades. We also predict that fish carbonate production may rise in response to future environmental changes in carbon dioxide, and thus become an increasingly important component of the inorganic carbon cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, R W -- Millero, F J -- Taylor, J R -- Walsh, P J -- Christensen, V -- Jennings, S -- Grosell, M -- BB/D005108/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F009364/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- ISIS 1766/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Jan 16;323(5912):359-62. doi: 10.1126/science.1157972.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biosciences, University of Exeter, Exeter EX4 4PS, UK. r.w.wilson@ex.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19150840" target="_blank"〉PubMed〈/a〉

    Description: Picoeukaryotes are a taxonomically diverse group of organisms less than 2 micrometers in diameter. Photosynthetic marine picoeukaryotes in the genus Micromonas thrive in ecosystems ranging from tropical to polar and could serve as sentinel organisms for biogeochemical fluxes of modern oceans during climate change. These broadly distributed primary producers belong to an anciently diverged sister clade to land plants. Although Micromonas isolates have high 18S ribosomal RNA gene identity, we found that genomes from two isolates shared only 90% of their predicted genes. Their independent evolutionary paths were emphasized by distinct riboswitch arrangements as well as the discovery of intronic repeat elements in one isolate, and in metagenomic data, but not in other genomes. Divergence appears to have been facilitated by selection and acquisition processes that actively shape the repertoire of genes that are mutually exclusive between the two isolates differently than the core genes. Analyses of the Micromonas genomes offer valuable insights into ecological differentiation and the dynamic nature of early plant evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worden, Alexandra Z -- Lee, Jae-Hyeok -- Mock, Thomas -- Rouze, Pierre -- Simmons, Melinda P -- Aerts, Andrea L -- Allen, Andrew E -- Cuvelier, Marie L -- Derelle, Evelyne -- Everett, Meredith V -- Foulon, Elodie -- Grimwood, Jane -- Gundlach, Heidrun -- Henrissat, Bernard -- Napoli, Carolyn -- McDonald, Sarah M -- Parker, Micaela S -- Rombauts, Stephane -- Salamov, Aasf -- Von Dassow, Peter -- Badger, Jonathan H -- Coutinho, Pedro M -- Demir, Elif -- Dubchak, Inna -- Gentemann, Chelle -- Eikrem, Wenche -- Gready, Jill E -- John, Uwe -- Lanier, William -- Lindquist, Erika A -- Lucas, Susan -- Mayer, Klaus F X -- Moreau, Herve -- Not, Fabrice -- Otillar, Robert -- Panaud, Olivier -- Pangilinan, Jasmyn -- Paulsen, Ian -- Piegu, Benoit -- Poliakov, Aaron -- Robbens, Steven -- Schmutz, Jeremy -- Toulza, Eve -- Wyss, Tania -- Zelensky, Alexander -- Zhou, Kemin -- Armbrust, E Virginia -- Bhattacharya, Debashish -- Goodenough, Ursula W -- Van de Peer, Yves -- Grigoriev, Igor V -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):268-72. doi: 10.1126/science.1167222.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Monterey Bay Aquarium Research Institute, Moss Landing, CA 95039 USA. azworden@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359590" target="_blank"〉PubMed〈/a〉

    Description: Biologists have long been fascinated by the exceptionally high diversity displayed by some evolutionary groups. Adaptive radiation in such clades is not only spectacular, but is also an extremely complex process influenced by a variety of ecological, genetic, and developmental factors and strongly dependent on historical contingencies. Using modeling approaches, we identify 10 general patterns concerning the temporal, spatial, and genetic/morphological properties of adaptive radiation. Some of these are strongly supported by empirical work, whereas for others, empirical support is more tentative. In almost all cases, more data are needed. Future progress in our understanding of adaptive radiation will be most successful if theoretical and empirical approaches are integrated, as has happened in other areas of evolutionary biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gavrilets, Sergey -- Losos, Jonathan B -- GM56693/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):732-7. doi: 10.1126/science.1157966.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, National Institute for Mathematical and Biological Synthesis, University of Tennessee, Knoxville, TN 37996, USA. sergey@tiem.utk.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197052" target="_blank"〉PubMed〈/a〉

    Description: The Brazilian Amazon is globally important for biodiversity, climate, and geochemical cycles, but is also among the least developed regions in Brazil. Economic development is often pursued through forest conversion for cattle ranching and agriculture, mediated by logging. However, on the basis of an assessment of 286 municipalities in different stages of deforestation, we found a boom-and-bust pattern in levels of human development across the deforestation frontier. Relative standards of living, literacy, and life expectancy increase as deforestation begins but then decline as the frontier evolves, so that pre- and postfrontier levels of human development are similarly low. New financial incentives and policies are creating opportunities for a more sustained development trajectory that is not based on the depletion of nature and ecosystem services.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rodrigues, Ana S L -- Ewers, Robert M -- Parry, Luke -- Souza, Carlos Jr -- Verissimo, Adalberto -- Balmford, Andrew -- New York, N.Y. -- Science. 2009 Jun 12;324(5933):1435-7. doi: 10.1126/science.1174002.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Conservation Science Group, Department of Zoology, University of Cambridge, Cambridge CB2 3EJ, UK. ana.rodrigues@cefe.cnrs.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19520958" target="_blank"〉PubMed〈/a〉

    Description: Similarities in the behavior of diverse animal species that form large groups have motivated attempts to establish general principles governing animal group behavior. It has been difficult, however, to make quantitative measurements of the temporal and spatial behavior of extensive animal groups in the wild, such as bird flocks, fish shoals, and locust swarms. By quantifying the formation processes of vast oceanic fish shoals during spawning, we show that (i) a rapid transition from disordered to highly synchronized behavior occurs as population density reaches a critical value; (ii) organized group migration occurs after this transition; and (iii) small sets of leaders significantly influence the actions of much larger groups. Each of these findings confirms general theoretical predictions believed to apply in nature irrespective of animal species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makris, Nicholas C -- Ratilal, Purnima -- Jagannathan, Srinivasan -- Gong, Zheng -- Andrews, Mark -- Bertsatos, Ioannis -- Godo, Olav Rune -- Nero, Redwood W -- Jech, J Michael -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1734-7. doi: 10.1126/science.1169441.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139, USA. makris@mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325116" target="_blank"〉PubMed〈/a〉

    Description: Insights into what stabilizes natural food webs have always been limited by a fundamental dilemma: Studies either need to make unwarranted simplifying assumptions, which undermines their relevance, or only examine few replicates of small food webs, which hampers the robustness of findings. We used generalized modeling to study several billion replicates of food webs with nonlinear interactions and up to 50 species. In this way, first we show that higher variability in link strengths stabilizes food webs only when webs are relatively small, whereas larger webs are instead destabilized. Second, we reveal a new power law describing how food-web stability scales with the number of species and their connectance. Third, we report two universal rules: Food-web stability is enhanced when (i) species at a high trophic level feed on multiple prey species and (ii) species at an intermediate trophic level are fed upon by multiple predator species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gross, Thilo -- Rudolf, Lars -- Levin, Simon A -- Dieckmann, Ulf -- New York, N.Y. -- Science. 2009 Aug 7;325(5941):747-50. doi: 10.1126/science.1173536.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Physics of Complex Systems, Nothnitzer Strasse 38, 01187 Dresden, Germany. thilo.gross@physics.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19661430" target="_blank"〉PubMed〈/a〉

    Description: European eels (Anguilla anguilla) undertake a approximately 5000-kilometer (km) spawning migration from Europe to the Sargasso Sea. The larvae are transported back to European waters by the Gulf Stream and North Atlantic Drift. However, details of the spawning migration remain unknown because tracking eels in the Atlantic Ocean has, so far, eluded study. Recent advances in satellite tracking enable investigation of migratory behavior of large ocean-dwelling animals. However, sizes of available tags have precluded tracking smaller animals like European eels. Here, we present information about the swimming direction, depth, and migratory behavior of European eels during spawning migration, based on a miniaturized pop-up satellite archival transmitter. Although the tagging experiment fell short of revealing the full migration to the Sargasso Sea, the data covered the first 1300 km and provided unique insights.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aarestrup, Kim -- Okland, Finn -- Hansen, Michael M -- Righton, David -- Gargan, Patrik -- Castonguay, Martin -- Bernatchez, Louis -- Howey, Paul -- Sparholt, Henrik -- Pedersen, Michael I -- McKinley, Robert S -- New York, N.Y. -- Science. 2009 Sep 25;325(5948):1660. doi: 10.1126/science.1178120.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Technical University of Denmark (DTU), National Institute of Aquatic Resources, Vejlsovej 39, DK-8600 Silkeborg, Denmark. kaa@aqua.dtu.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19779192" target="_blank"〉PubMed〈/a〉

    Description: A global biofuels program will lead to intense pressures on land supply and can increase greenhouse gas emissions from land-use changes. Using linked economic and terrestrial biogeochemistry models, we examined direct and indirect effects of possible land-use changes from an expanded global cellulosic bioenergy program on greenhouse gas emissions over the 21st century. Our model predicts that indirect land use will be responsible for substantially more carbon loss (up to twice as much) than direct land use; however, because of predicted increases in fertilizer use, nitrous oxide emissions will be more important than carbon losses themselves in terms of warming potential. A global greenhouse gas emissions policy that protects forests and encourages best practices for nitrogen fertilizer use can dramatically reduce emissions associated with biofuels production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Melillo, Jerry M -- Reilly, John M -- Kicklighter, David W -- Gurgel, Angelo C -- Cronin, Timothy W -- Paltsev, Sergey -- Felzer, Benjamin S -- Wang, Xiaodong -- Sokolov, Andrei P -- Schlosser, C Adam -- New York, N.Y. -- Science. 2009 Dec 4;326(5958):1397-9. doi: 10.1126/science.1180251.

    Description: The increase in anthropogenic carbon dioxide emissions and attendant increase in ocean acidification and sea ice melt act together to decrease the saturation state of calcium carbonate in the Canada Basin of the Arctic Ocean. In 2008, surface waters were undersaturated with respect to aragonite, a relatively soluble form of calcium carbonate found in plankton and invertebrates. Undersaturation was found to be a direct consequence of the recent extensive melting of sea ice in the Canada Basin. In addition, the retreat of the ice edge well past the shelf-break has produced conditions favorable to enhanced upwelling of subsurface, aragonite-undersaturated water onto the Arctic continental shelf. Undersaturation will affect both planktonic and benthic calcifying biota and therefore the composition of the Arctic ecosystem.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamamoto-Kawai, Michiyo -- McLaughlin, Fiona A -- Carmack, Eddy C -- Nishino, Shigeto -- Shimada, Koji -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1098-100. doi: 10.1126/science.1174190.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Fisheries and Oceans, Institute of Ocean Sciences, 9860 West Saanich Road, Sidney, British Columbia V8L 4B2, Canada. michiyo.kawai@dfo-mpo.gc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965425" target="_blank"〉PubMed〈/a〉

    Description: The 260-million-year-old Emeishan volcanic province of southwest China overlies and is interbedded with Middle Permian carbonates that contain a record of the Guadalupian mass extinction. Sections in the region thus provide an opportunity to directly monitor the relative timing of extinction and volcanism within the same locations. These show that the onset of volcanism was marked by both large phreatomagmatic eruptions and extinctions amongst fusulinacean foraminifers and calcareous algae. The temporal coincidence of these two phenomena supports the idea of a cause-and-effect relationship. The crisis predates the onset of a major negative carbon isotope excursion that points to subsequent severe disturbance of the ocean-atmosphere carbon cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wignall, Paul B -- Sun, Yadong -- Bond, David P G -- Izon, Gareth -- Newton, Robert J -- Vedrine, Stephanie -- Widdowson, Mike -- Ali, Jason R -- Lai, Xulong -- Jiang, Haishui -- Cope, Helen -- Bottrell, Simon H -- New York, N.Y. -- Science. 2009 May 29;324(5931):1179-82. doi: 10.1126/science.1171956.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Earth and Environment, University of Leeds, Leeds LS2 9JT, UK. p.wignall@see.leeds.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19478179" target="_blank"〉PubMed〈/a〉

    Description: We describe a sensitive metabolite array for genome sequence-independent functional analysis of metabolic phenotypes and networks, the reactomes, of cell populations and communities. The array includes 1676 dye-linked substrate compounds collectively representing central metabolic pathways of all forms of life. Application of cell extracts to the array leads to specific binding of enzymes to cognate substrates, transformation to products, and concomitant activation of the dye signals. Proof of principle was shown by reconstruction of the metabolic maps of model bacteria. Utility of the array for unsequenced organisms was demonstrated by reconstruction of the global metabolisms of three microbial communities derived from acidic volcanic pool, deep-sea brine lake, and hydrocarbon-polluted seawater. Enzymes of interest are captured on nanoparticles coated with cognate metabolites, sequenced, and their functions unequivocally established.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beloqui, Ana -- Guazzaroni, Maria-Eugenia -- Pazos, Florencio -- Vieites, Jose M -- Godoy, Marta -- Golyshina, Olga V -- Chernikova, Tatyana N -- Waliczek, Agnes -- Silva-Rocha, Rafael -- Al-Ramahi, Yamal -- La Cono, Violetta -- Mendez, Carmen -- Salas, Jose A -- Solano, Roberto -- Yakimov, Michail M -- Timmis, Kenneth N -- Golyshin, Peter N -- Ferrer, Manuel -- New York, N.Y. -- Science. 2009 Oct 9;326(5950):252-7. doi: 10.1126/science.1174094.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CSIC, Institute of Catalysis, 28049 Madrid, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19815770" target="_blank"〉PubMed〈/a〉

    Description: Limiting atmospheric carbon dioxide (CO2) concentrations to low levels requires strategies to manage anthropogenic carbon emissions from terrestrial systems as well as fossil fuel and industrial sources. We explore the implications of fully integrating terrestrial systems and the energy system into a comprehensive mitigation regime that limits atmospheric CO2 concentrations. We find that this comprehensive approach lowers the cost of meeting environmental goals but also carries with it profound implications for agriculture: Unmanaged ecosystems and forests expand, and food crop and livestock prices rise. Finally, we find that future improvement in food crop productivity directly affects land-use change emissions, making the technology for growing crops potentially important for limiting atmospheric CO2 concentrations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wise, Marshall -- Calvin, Katherine -- Thomson, Allison -- Clarke, Leon -- Bond-Lamberty, Benjamin -- Sands, Ronald -- Smith, Steven J -- Janetos, Anthony -- Edmonds, James -- New York, N.Y. -- Science. 2009 May 29;324(5931):1183-6. doi: 10.1126/science.1168475.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pacific Northwest National Laboratory, Joint Global Change Research Institute at the University of Maryland-College Park, 5825 University Research Court, Suite 3500, College Park, MD 20740, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19478180" target="_blank"〉PubMed〈/a〉

    Description: Adaptation is a central focus of biology, although it can be difficult to identify both the strength and agent of selection and the underlying molecular mechanisms causing change. We studied cryptically colored deer mice living on the Nebraska Sand Hills and show that their light coloration stems from a novel banding pattern on individual hairs produced by an increase in Agouti expression caused by a cis-acting mutation (or mutations), which either is or is closely linked to a single amino acid deletion in Agouti that appears to be under selection. Furthermore, our data suggest that this derived Agouti allele arose de novo after the formation of the Sand Hills. These findings reveal one means by which genetic, developmental, and evolutionary mechanisms can drive rapid adaptation under ecological pressure.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2736094/" 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/PMC2736094/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Linnen, Catherine R -- Kingsley, Evan P -- Jensen, Jeffrey D -- Hoekstra, Hopi E -- F32 GM083073-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 28;325(5944):1095-8. doi: 10.1126/science.1175826.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic and Evolutionary Biology and the Museum of Comparative Zoology, Harvard University, 26 Oxford Street, Cambridge, MA 02138, USA. clinnen@oeb.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19713521" target="_blank"〉PubMed〈/a〉

    Description: Reef-building corals are under increasing physiological stress from a changing climate and ocean absorption of increasing atmospheric carbon dioxide. We investigated 328 colonies of massive Porites corals from 69 reefs of the Great Barrier Reef (GBR) in Australia. Their skeletal records show that throughout the GBR, calcification has declined by 14.2% since 1990, predominantly because extension (linear growth) has declined by 13.3%. The data suggest that such a severe and sudden decline in calcification is unprecedented in at least the past 400 years. Calcification increases linearly with increasing large-scale sea surface temperature but responds nonlinearly to annual temperature anomalies. The causes of the decline remain unknown; however, this study suggests that increasing temperature stress and a declining saturation state of seawater aragonite may be diminishing the ability of GBR corals to deposit calcium carbonate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De'ath, Glenn -- Lough, Janice M -- Fabricius, Katharina E -- New York, N.Y. -- Science. 2009 Jan 2;323(5910):116-9. doi: 10.1126/science.1165283.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Australian Institute of Marine Science, Townsville, Queensland 4810, Australia. g.death@aims.gov.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19119230" target="_blank"〉PubMed〈/a〉

    Description: Ecological speciation is considered an adaptive response to selection for local adaptation. However, besides suitable ecological conditions, the process requires assortative mating to protect the nascent species from homogenization by gene flow. By means of a simple model, we demonstrate that disruptive ecological selection favors the evolution of sexual preferences for ornaments that signal local adaptation. Such preferences induce assortative mating with respect to ecological characters and enhance the strength of disruptive selection. Natural and sexual selection thus work in concert to achieve local adaptation and reproductive isolation, even in the presence of substantial gene flow. The resulting speciation process ensues without the divergence of mating preferences, avoiding problems that have plagued previous models of speciation by sexual selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Doorn, G Sander -- Edelaar, Pim -- Weissing, Franz J -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1704-7. doi: 10.1126/science.1181661.

    Description: Environmental change, including climate change, can cause rapid phenotypic change via both ecological and evolutionary processes. Because ecological and evolutionary dynamics are intimately linked, a major challenge is to identify their relative roles. We exactly decomposed the change in mean body weight in a free-living population of Soay sheep into all the processes that contribute to change. Ecological processes contribute most, with selection--the underpinning of adaptive evolution--explaining little of the observed phenotypic trend. Our results enable us to explain why selection has so little effect even though weight is heritable, and why environmental change has caused a decline in the body size of Soay sheep.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ozgul, Arpat -- Tuljapurkar, Shripad -- Benton, Tim G -- Pemberton, Josephine M -- Clutton-Brock, Tim H -- Coulson, Tim -- P01 AG022500/AG/NIA NIH HHS/ -- P01/AG/22500/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 24;325(5939):464-7. doi: 10.1126/science.1173668.

    Description: The response of the Greenland ice sheet to global warming is a source of concern notably because of its potential contribution to changes in the sea level. We demonstrated the natural vulnerability of the ice sheet by using pollen records from marine sediment off southwest Greenland that indicate important changes of the vegetation in Greenland over the past million years. The vegetation that developed over southern Greenland during the last interglacial period is consistent with model experiments, suggesting a reduced volume of the Greenland ice sheet. Abundant spruce pollen indicates that boreal coniferous forest developed some 400,000 years ago during the "warm" interval of marine isotope stage 11, providing a time frame for the development and decline of boreal ecosystems over a nearly ice-free Greenland.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Vernal, Anne -- Hillaire-Marcel, Claude -- New York, N.Y. -- Science. 2008 Jun 20;320(5883):1622-5. doi: 10.1126/science.1153929.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉GEOTOP Geochemistry and Geodynamics Research Center-Universite du Quebec a Montreal, Case Postale 8888, succursale Centre-Ville, Montreal, Quebec H3C 3P8, Canada. devernal.anne@uqam.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18566284" target="_blank"〉PubMed〈/a〉

    Description: Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of the world's mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine mammals. Global macroecological patterns are very different for land and marine species but suggest common mechanisms driving diversity and endemism across systems. Compared with land species, threat levels are higher among marine mammals, driven by different processes (accidental mortality and pollution, rather than habitat loss), and are spatially distinct (peaking in northern oceans, rather than in Southeast Asia). Marine mammals are also disproportionately poorly known. These data are made freely available to support further scientific developments and conservation action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schipper, Jan -- Chanson, Janice S -- Chiozza, Federica -- Cox, Neil A -- Hoffmann, Michael -- Katariya, Vineet -- Lamoreux, John -- Rodrigues, Ana S L -- Stuart, Simon N -- Temple, Helen J -- Baillie, Jonathan -- Boitani, Luigi -- Lacher, Thomas E Jr -- Mittermeier, Russell A -- Smith, Andrew T -- Absolon, Daniel -- Aguiar, John M -- Amori, Giovanni -- Bakkour, Noura -- Baldi, Ricardo -- Berridge, Richard J -- Bielby, Jon -- Black, Patricia Ann -- Blanc, J Julian -- Brooks, Thomas M -- Burton, James A -- Butynski, Thomas M -- Catullo, Gianluca -- Chapman, Roselle -- Cokeliss, Zoe -- Collen, Ben -- Conroy, Jim -- Cooke, Justin G -- da Fonseca, Gustavo A B -- Derocher, Andrew E -- Dublin, Holly T -- Duckworth, J W -- Emmons, Louise -- Emslie, Richard H -- Festa-Bianchet, Marco -- Foster, Matt -- Foster, Sabrina -- Garshelis, David L -- Gates, Cormack -- Gimenez-Dixon, Mariano -- Gonzalez, Susana -- Gonzalez-Maya, Jose Fernando -- Good, Tatjana C -- Hammerson, Geoffrey -- Hammond, Philip S -- Happold, David -- Happold, Meredith -- Hare, John -- Harris, Richard B -- Hawkins, Clare E -- Haywood, Mandy -- Heaney, Lawrence R -- Hedges, Simon -- Helgen, Kristofer M -- Hilton-Taylor, Craig -- Hussain, Syed Ainul -- Ishii, Nobuo -- Jefferson, Thomas A -- Jenkins, Richard K B -- Johnston, Charlotte H -- Keith, Mark -- Kingdon, Jonathan -- Knox, David H -- Kovacs, Kit M -- Langhammer, Penny -- Leus, Kristin -- Lewison, Rebecca -- Lichtenstein, Gabriela -- Lowry, Lloyd F -- Macavoy, Zoe -- Mace, Georgina M -- Mallon, David P -- Masi, Monica -- McKnight, Meghan W -- Medellin, Rodrigo A -- Medici, Patricia -- Mills, Gus -- Moehlman, Patricia D -- Molur, Sanjay -- Mora, Arturo -- Nowell, Kristin -- Oates, John F -- Olech, Wanda -- Oliver, William R L -- Oprea, Monik -- Patterson, Bruce D -- Perrin, William F -- Polidoro, Beth A -- Pollock, Caroline -- Powel, Abigail -- Protas, Yelizaveta -- Racey, Paul -- Ragle, Jim -- Ramani, Pavithra -- Rathbun, Galen -- Reeves, Randall R -- Reilly, Stephen B -- Reynolds, John E 3rd -- Rondinini, Carlo -- Rosell-Ambal, Ruth Grace -- Rulli, Monica -- Rylands, Anthony B -- Savini, Simona -- Schank, Cody J -- Sechrest, Wes -- Self-Sullivan, Caryn -- Shoemaker, Alan -- Sillero-Zubiri, Claudio -- De Silva, Naamal -- Smith, David E -- Srinivasulu, Chelmala -- Stephenson, Peter J -- van Strien, Nico -- Talukdar, Bibhab Kumar -- Taylor, Barbara L -- Timmins, Rob -- Tirira, Diego G -- Tognelli, Marcelo F -- Tsytsulina, Katerina -- Veiga, Liza M -- Vie, Jean-Christophe -- Williamson, Elizabeth A -- Wyatt, Sarah A -- Xie, Yan -- Young, Bruce E -- New York, N.Y. -- Science. 2008 Oct 10;322(5899):225-30. doi: 10.1126/science.1165115.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉International Union for Conservation of Nature (IUCN) Species Programme, IUCN, 28 Rue Mauverney, 1196 Gland, Switzerland. jan.schipper@iucn.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18845749" target="_blank"〉PubMed〈/a〉

    Description: Deep avian evolutionary relationships have been difficult to resolve as a result of a putative explosive radiation. Our study examined approximately 32 kilobases of aligned nuclear DNA sequences from 19 independent loci for 169 species, representing all major extant groups, and recovered a robust phylogeny from a genome-wide signal supported by multiple analytical methods. We documented well-supported, previously unrecognized interordinal relationships (such as a sister relationship between passerines and parrots) and corroborated previously contentious groupings (such as flamingos and grebes). Our conclusions challenge current classifications and alter our understanding of trait evolution; for example, some diurnal birds evolved from nocturnal ancestors. Our results provide a valuable resource for phylogenetic and comparative studies in birds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hackett, Shannon J -- Kimball, Rebecca T -- Reddy, Sushma -- Bowie, Rauri C K -- Braun, Edward L -- Braun, Michael J -- Chojnowski, Jena L -- Cox, W Andrew -- Han, Kin-Lan -- Harshman, John -- Huddleston, Christopher J -- Marks, Ben D -- Miglia, Kathleen J -- Moore, William S -- Sheldon, Frederick H -- Steadman, David W -- Witt, Christopher C -- Yuri, Tamaki -- New York, N.Y. -- Science. 2008 Jun 27;320(5884):1763-8. doi: 10.1126/science.1157704.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zoology Department, Field Museum of Natural History, 1400 South Lake Shore Drive, Chicago, IL 60605, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18583609" target="_blank"〉PubMed〈/a〉

    Description: The most abundant taxon of the Neoproterozoic soft-bodied biota near Ediacara, South Australia, occurs as clusters of similarly sized individuals, which suggests synchronous aggregate growth by spatfall. Tubes of Funisia dorothea gen. et sp. nov. were anchored within the shallow, sandy sea bed and lived in dense, typically monospecific concentrations. Tubes were composed of modular, serially repeating elements. Individuals grew by adding serial elements to the tubular body and by branching of tubes. Their construction and close-packed association imply likely affinity within the Porifera or Cnidaria. These data suggest that several of the most successful marine invertebrate ecological strategies known today were in place in Earth's oldest known metazoan ecosystems before the advent of skeletonization and widespread predation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Droser, Mary L -- Gehling, James G -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1660-2. doi: 10.1126/science.1152595.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, University of California, Riverside, CA 92521, USA.

    Description: Increasing quantities of atmospheric anthropogenic fixed nitrogen entering the open ocean could account for up to about a third of the ocean's external (nonrecycled) nitrogen supply and up to approximately 3% of the annual new marine biological production, approximately 0.3 petagram of carbon per year. This input could account for the production of up to approximately 1.6 teragrams of nitrous oxide (N2O) per year. Although approximately 10% of the ocean's drawdown of atmospheric anthropogenic carbon dioxide may result from this atmospheric nitrogen fertilization, leading to a decrease in radiative forcing, up to about two-thirds of this amount may be offset by the increase in N2O emissions. The effects of increasing atmospheric nitrogen deposition are expected to continue to grow in the future.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duce, R A -- LaRoche, J -- Altieri, K -- Arrigo, K R -- Baker, A R -- Capone, D G -- Cornell, S -- Dentener, F -- Galloway, J -- Ganeshram, R S -- Geider, R J -- Jickells, T -- Kuypers, M M -- Langlois, R -- Liss, P S -- Liu, S M -- Middelburg, J J -- Moore, C M -- Nickovic, S -- Oschlies, A -- Pedersen, T -- Prospero, J -- Schlitzer, R -- Seitzinger, S -- Sorensen, L L -- Uematsu, M -- Ulloa, O -- Voss, M -- Ward, B -- Zamora, L -- New York, N.Y. -- Science. 2008 May 16;320(5878):893-7. doi: 10.1126/science.1150369.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Oceanography and Atmospheric Sciences, Texas A&M University, College Station, TX 77843, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18487184" target="_blank"〉PubMed〈/a〉

    Description: Viruses shape microbial community structure and function by altering the fitness of their hosts and by promoting genetic exchange. The complexity of most natural ecosystems has precluded detailed studies of virus-host interactions. We reconstructed virus and host bacterial and archaeal genome sequences from community genomic data from two natural acidophilic biofilms. Viruses were matched to their hosts by analyzing spacer sequences that occur among clustered regularly interspaced short palindromic repeats (CRISPRs) that are a hallmark of virus resistance. Virus population genomic analyses provided evidence that extensive recombination shuffles sequence motifs sufficiently to evade CRISPR spacers. Only the most recently acquired spacers match coexisting viruses, which suggests that community stability is achieved by rapid but compensatory shifts in host resistance levels and virus population structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersson, Anders F -- Banfield, Jillian F -- New York, N.Y. -- Science. 2008 May 23;320(5879):1047-50. doi: 10.1126/science.1157358.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Earth and Planetary Science and Environmental Science, Policy, and Management, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18497291" target="_blank"〉PubMed〈/a〉

    Description: The archaeology of pre-Columbian polities in the Amazon River basin forces a reconsideration of early urbanism and long-term change in tropical forest landscapes. We describe settlement and land-use patterns of complex societies on the eve of European contact (after 1492) in the Upper Xingu region of the Brazilian Amazon. These societies were organized in articulated clusters, representing small independent polities, within a regional peer polity. These patterns constitute a "galactic" form of prehistoric urbanism, sharing features with small-scale urban polities in other areas. Understanding long-term change in coupled human-environment systems relating to these societies has implications for conservation and sustainable development, notably to control ecological degradation and maintain regional biodiversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heckenberger, Michael J -- Russell, J Christian -- Fausto, Carlos -- Toney, Joshua R -- Schmidt, Morgan J -- Pereira, Edithe -- Franchetto, Bruna -- Kuikuro, Afukaka -- New York, N.Y. -- Science. 2008 Aug 29;321(5893):1214-7. doi: 10.1126/science.1159769.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Florida, Gainesville, FL 32611, USA. mheck@ufl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18755979" target="_blank"〉PubMed〈/a〉

    Description: Fire is a global driver of carbon storage and converts a substantial proportion of plant biomass to black carbon (for example, charcoal), which remains in the soil for thousands of years. Black carbon is therefore often proposed as an important long-term sink of soil carbon. We ran a 10-year experiment in each of three boreal forest stands to show that fire-derived charcoal promotes loss of forest humus and that this is associated with enhancement of microbial activity by charcoal. This result shows that charcoal-induced losses of belowground carbon in forests can partially offset the benefits of charcoal as a long-term carbon sink.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wardle, David A -- Nilsson, Marie-Charlotte -- Zackrisson, Olle -- New York, N.Y. -- Science. 2008 May 2;320(5876):629. doi: 10.1126/science.1154960.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Forest Ecology and Management, Swedish University of Agricultural Sciences, SE901-83 Umea, Sweden. david.wardle@svek.slu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18451294" target="_blank"〉PubMed〈/a〉

    Description: Globally, priority areas for biodiversity are relatively well known, yet few detailed plans exist to direct conservation action within them, despite urgent need. Madagascar, like other globally recognized biodiversity hot spots, has complex spatial patterns of endemism that differ among taxonomic groups, creating challenges for the selection of within-country priorities. We show, in an analysis of wide taxonomic and geographic breadth and high spatial resolution, that multitaxonomic rather than single-taxon approaches are critical for identifying areas likely to promote the persistence of most species. Our conservation prioritization, facilitated by newly available techniques, identifies optimal expansion sites for the Madagascar government's current goal of tripling the land area under protection. Our findings further suggest that high-resolution multitaxonomic approaches to prioritization may be necessary to ensure protection for biodiversity in other global hot spots.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kremen, C -- Cameron, A -- Moilanen, A -- Phillips, S J -- Thomas, C D -- Beentje, H -- Dransfield, J -- Fisher, B L -- Glaw, F -- Good, T C -- Harper, G J -- Hijmans, R J -- Lees, D C -- Louis, E Jr -- Nussbaum, R A -- Raxworthy, C J -- Razafimpahanana, A -- Schatz, G E -- Vences, M -- Vieites, D R -- Wright, P C -- Zjhra, M L -- New York, N.Y. -- Science. 2008 Apr 11;320(5873):222-6. doi: 10.1126/science.1155193.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Environmental Sciences, Policy and Management, 137 Mulford Hall, University of California, Berkeley, CA 94720-3114, USA. ckremen@nature.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18403708" target="_blank"〉PubMed〈/a〉

    Description: Hotspots of high species diversity are a prominent feature of modern global biodiversity patterns. Fossil and molecular evidence is starting to reveal the history of these hotspots. There have been at least three marine biodiversity hotspots during the past 50 million years. They have moved across almost half the globe, with their timing and locations coinciding with major tectonic events. The birth and death of successive hotspots highlights the link between environmental change and biodiversity patterns. The antiquity of the taxa in the modern Indo-Australian Archipelago hotspot emphasizes the role of pre-Pleistocene events in shaping modern diversity patterns.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Renema, W -- Bellwood, D R -- Braga, J C -- Bromfield, K -- Hall, R -- Johnson, K G -- Lunt, P -- Meyer, C P -- McMonagle, L B -- Morley, R J -- O'Dea, A -- Todd, J A -- Wesselingh, F P -- Wilson, M E J -- Pandolfi, J M -- New York, N.Y. -- Science. 2008 Aug 1;321(5889):654-7. doi: 10.1126/science.1155674.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nationaal Natuurhistorisch Museum, Naturalis, 2300 RA, Leiden, Netherlands.

    Description: Humans continue to transform the global nitrogen cycle at a record pace, reflecting an increased combustion of fossil fuels, growing demand for nitrogen in agriculture and industry, and pervasive inefficiencies in its use. Much anthropogenic nitrogen is lost to air, water, and land to cause a cascade of environmental and human health problems. Simultaneously, food production in some parts of the world is nitrogen-deficient, highlighting inequities in the distribution of nitrogen-containing fertilizers. Optimizing the need for a key human resource while minimizing its negative consequences requires an integrated interdisciplinary approach and the development of strategies to decrease nitrogen-containing waste.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Galloway, James N -- Townsend, Alan R -- Erisman, Jan Willem -- Bekunda, Mateete -- Cai, Zucong -- Freney, John R -- Martinelli, Luiz A -- Seitzinger, Sybil P -- Sutton, Mark A -- New York, N.Y. -- Science. 2008 May 16;320(5878):889-92. doi: 10.1126/science.1136674.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Environmental Sciences Department, University of Virginia, Charlottesville, VA 22904, USA. jng@virginia.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18487183" target="_blank"〉PubMed〈/a〉

    Description: Atlantic bluefin tuna populations are in steep decline, and an improved understanding of connectivity between individuals from eastern (Mediterranean Sea) and western (Gulf of Mexico) spawning areas is needed to manage remaining fisheries. Chemical signatures in the otoliths of yearlings from regional nurseries were distinct and served as natural tags to assess natal homing and mixing. Adults showed high rates of natal homing to both eastern and western spawning areas. Trans-Atlantic movement (east to west) was significant and size-dependent, with individuals of Mediterranean origin mixing with the western population in the U.S. Atlantic. The largest (oldest) bluefin tuna collected near the northern extent of their range in North American waters were almost exclusively of western origin, indicating that this region represents critical habitat for the western population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rooker, Jay R -- Secor, David H -- De Metrio, Gregorio -- Schloesser, Ryan -- Block, Barbara A -- Neilson, John D -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):742-4. doi: 10.1126/science.1161473.

    Description: Most prior studies have found that substituting biofuels for gasoline will reduce greenhouse gases because biofuels sequester carbon through the growth of the feedstock. These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert forest and grassland to new cropland to replace the grain (or cropland) diverted to biofuels. By using a worldwide agricultural model to estimate emissions from land-use change, we found that corn-based ethanol, instead of producing a 20% savings, nearly doubles greenhouse emissions over 30 years and increases greenhouse gases for 167 years. Biofuels from switchgrass, if grown on U.S. corn lands, increase emissions by 50%. This result raises concerns about large biofuel mandates and highlights the value of using waste products.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Searchinger, Timothy -- Heimlich, Ralph -- Houghton, R A -- Dong, Fengxia -- Elobeid, Amani -- Fabiosa, Jacinto -- Tokgoz, Simla -- Hayes, Dermot -- Yu, Tun-Hsiang -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1238-40. doi: 10.1126/science.1151861.

    Description: Paleoecological evidence from the past 8000 years in the Galapagos Islands shows that six presumed introduced or doubtfully native species (Ageratum conyzoides, Borreria laevis/Diodia radula-type, Brickellia diffusa, Cuphea carthagenensis, Hibiscus diversifolius, and Ranunculus flagelliformis) are in fact native to the archipelago. Fossil pollen and macrofossils from four sites in the highlands of Santa Cruz Island reveal that all were present thousands of years before the advent of human impact, refuting their classification as introduced species. These findings have substantial implications not only for conservation in Galapagos but for the management of introduced species and pantropical weeds in general.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Leeuwen, Jacqueline F N -- Froyd, Cynthia A -- van der Knaap, W O -- Coffey, Emily E -- Tye, Alan -- Willis, Katherine J -- New York, N.Y. -- Science. 2008 Nov 21;322(5905):1206. doi: 10.1126/science.1163454.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Plant Sciences and Oeschger Centre for Climate Change Research, University of Bern, Altenbergrain 21, CH-3013 Bern, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19023075" target="_blank"〉PubMed〈/a〉

    Description: The fossil record is the only direct source of data for studying modes (patterns) and rates of morphological change over long periods of time. Determining modes and rates is important for understanding macroevolutionary processes, but just how modes and rates vary within a taxon, and why, remain largely unaddressed. We examined patterns of morphological change in the shell of the Mesozoic marine bivalve genus Buchia over its geographic and temporal range. Most modes conformed to either random walks or stasis, and both modes and rates showed variability between locations. For example, stasis was more common in deeper marine environments, whereas random walks occurred more often at the highest paleolatitudes studied. These results indicate that the environment can play an important role in shaping patterns of evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grey, Melissa -- Haggart, James W -- Smith, Paul L -- New York, N.Y. -- Science. 2008 Nov 21;322(5905):1238-41. doi: 10.1126/science.1162046.
