    Details
    Publication Date: 2006-10-21
    Description: Dey and Joshi (Reports, 21 April 2006, p. 434) studied replicate laboratory populations of Drosophila and reported that low migration led to asynchrony among subpopulations. We argue that this unexpected outcome may be due to variation in the initial size of the subpopulations and uncontrolled stochasticity in the experiments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ranta, Esa -- Kaitala, Veijo -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):420; author reply 420.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Integrative Ecology Unit, Department of Biological and Environmental Sciences, P.O.

    Group competition, reproductive leveling, and the evolution of human altruism (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-13
    Description: Humans behave altruistically in natural settings and experiments. A possible explanation-that groups with more altruists survive when groups compete-has long been judged untenable on empirical grounds for most species. But there have been no empirical tests of this explanation for humans. My empirical estimates show that genetic differences between early human groups are likely to have been great enough so that lethal intergroup competition could account for the evolution of altruism. Crucial to this process were distinctive human practices such as sharing food beyond the immediate family, monogamy, and other forms of reproductive leveling. These culturally transmitted practices presuppose advanced cognitive and linguistic capacities, possibly accounting for the distinctive forms of altruism found in our species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowles, Samuel -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1569-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA, and Universita di Siena, 17 Piazza San Francesco, Siena, Italy. bowles@santafe.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158320" target="_blank"〉PubMed〈/a〉

    Emergence of drug-resistant influenza virus: population dynamical considerations (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-22
    Description: Given the considerable challenges to the rapid development of an effective vaccine against influenza, antiviral agents will play an important role as a first-line defense if a new pandemic occurs. The large-scale use of drugs for chemoprophylaxis and treatment will impose strong selection for the evolution of drug-resistant strains. The ensuing transmission of those strains could substantially limit the effectiveness of the drugs as a first-line defense. Summarizing recent data on the rate at which the treatment of influenza infection generates resistance de novo and on the transmission fitness of resistant virus, we discuss possible implications for the epidemiological spread of drug resistance in the context of an established population dynamic model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Regoes, Roland R -- Bonhoeffer, Sebastian -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):389-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Integrative Biology, ETH Zurich, ETH Zentrum CHN K12.1, Universitatsstrasse 16, CH 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16627735" target="_blank"〉PubMed〈/a〉

    Nonrandom processes maintain diversity in tropical forests (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-28
    Description: An ecological community's species diversity tends to erode through time as a result of stochastic extinction, competitive exclusion, and unstable host-enemy dynamics. This erosion of diversity can be prevented over the short term if recruits are highly diverse as a result of preferential recruitment of rare species or, alternatively, if rare species survive preferentially, which increases diversity as the ages of the individuals increase. Here, we present census data from seven New and Old World tropical forest dynamics plots that all show the latter pattern. Within local areas, the trees that survived were as a group more diverse than those that were recruited or those that died. The larger (and therefore on average older) survivors were more diverse within local areas than the smaller survivors. When species were rare in a local area, they had a higher survival rate than when they were common, resulting in enrichment for rare species and increasing diversity with age and size class in these complex ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wills, Christopher -- Harms, Kyle E -- Condit, Richard -- King, David -- Thompson, Jill -- He, Fangliang -- Muller-Landau, Helene C -- Ashton, Peter -- Losos, Elizabeth -- Comita, Liza -- Hubbell, Stephen -- Lafrankie, James -- Bunyavejchewin, Sarayudh -- Dattaraja, H S -- Davies, Stuart -- Esufali, Shameema -- Foster, Robin -- Gunatilleke, Nimal -- Gunatilleke, Savitri -- Hall, Pamela -- Itoh, Akira -- John, Robert -- Kiratiprayoon, Somboon -- de Lao, Suzanne Loo -- Massa, Marie -- Nath, Cheryl -- Noor, Md Nur Supardi -- Kassim, Abdul Rahman -- Sukumar, Raman -- Suresh, Hebbalalu Satyanarayana -- Sun, I-Fang -- Tan, Sylvester -- Yamakura, Takuo -- Zimmerman, Jess -- New York, N.Y. -- Science. 2006 Jan 27;311(5760):527-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biological Sciences, University of California, San Diego, La Jolla, CA 92093-0116, USA. cwills@ucsd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16439661" target="_blank"〉PubMed〈/a〉

    A major ecosystem shift in the northern Bering Sea (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-03-11
    Description: Until recently, northern Bering Sea ecosystems were characterized by extensive seasonal sea ice cover, high water column and sediment carbon production, and tight pelagic-benthic coupling of organic production. Here, we show that these ecosystems are shifting away from these characteristics. Changes in biological communities are contemporaneous with shifts in regional atmospheric and hydrographic forcing. In the past decade, geographic displacement of marine mammal population distributions has coincided with a reduction of benthic prey populations, an increase in pelagic fish, a reduction in sea ice, and an increase in air and ocean temperatures. These changes now observed on the shallow shelf of the northern Bering Sea should be expected to affect a much broader portion of the Pacific-influenced sector of the Arctic Ocean.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grebmeier, Jacqueline M -- Overland, James E -- Moore, Sue E -- Farley, Ed V -- Carmack, Eddy C -- Cooper, Lee W -- Frey, Karen E -- Helle, John H -- McLaughlin, Fiona A -- McNutt, S Lyn -- New York, N.Y. -- Science. 2006 Mar 10;311(5766):1461-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marine Biogeochemistry and Ecology Group, Department of Ecology and Evolutionary Biology, 10515 Research Drive, Building A, Suite 100, University of Tennessee, Knoxville, TN 37932, USA. jgrebmei@utk.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16527980" target="_blank"〉PubMed〈/a〉

    Long-distance dispersal of plants (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-12
    Description: Long-distance dispersal (LDD) of plants poses challenges to research because it involves rare events driven by complex and highly stochastic processes. The current surge of renewed interest in LDD, motivated by growing recognition of its critical importance for natural populations and communities and for humanity, promises an improved, quantitatively derived understanding of LDD. To gain deep insights into the patterns, mechanisms, causes, and consequences of LDD, we must look beyond the standard dispersal vectors and the mean trend of the distribution of dispersal distances. "Nonstandard" mechanisms such as extreme climatic events and generalized LDD vectors seem to hold the greatest explanatory power for the drastic deviations from the mean trend, deviations that make the nearly impossible LDD a reality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nathan, Ran -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):786-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Movement Ecology Laboratory, Department of Evolution, Systematics and Ecology, Alexander Silberman Institute of Life Sciences, Hebrew University of Jerusalem, Givat Ram, 91904 Jerusalem, Israel. rnathan@cc.huji.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902126" target="_blank"〉PubMed〈/a〉

    Stability via asynchrony in Drosophila metapopulations with low migration rates (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-22
    Description: Very few experimental studies have examined how migration rate affects metapopulation dynamics and stability. We studied the dynamics of replicate laboratory metapopulations of Drosophila under different migration rates. Low migration stabilized metapopulation dynamics, while promoting unstable subpopulation dynamics, by inducing asynchrony among neighboring subpopulations. High migration synchronized subpopulation dynamics, thereby destabilizing the metapopulations. Contrary to some theoretical predictions, increased migration did not affect average population size. Simulations based on a simple non-species-specific population growth model captured most features of the data, which suggests that our results are generalizable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dey, Sutirth -- Joshi, Amitabh -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):434-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Evolutionary Biology Laboratory, Evolutionary & Organismal Biology Unit, Jawaharlal Nehru Centre for Advanced Scientific Research, Jakkur P.O., Bangalore 560 064, India.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16627743" target="_blank"〉PubMed〈/a〉

    Loss of a harvested fish species disrupts carbon flow in a diverse tropical river (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-12
    Description: Harvesting threatens many vertebrate species, yet few whole-system manipulations have been conducted to predict the consequences of vertebrate losses on ecosystem function. Here, we show that a harvested migratory detrital-feeding fish (Prochilodontidae: Prochilodus mariae) modulates carbon flow and ecosystem metabolism. Natural declines in and experimental removal of Prochilodus decreased downstream transport of organic carbon and increased primary production and respiration. Thus, besides its economic value, Prochilodus is a critical ecological component of South American rivers. Lack of functional redundancy for this species highlights the importance of individual species and, contrary to theory, suggests that losing one species from lower trophic levels can affect ecosystem functioning even in species-rich ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taylor, Brad W -- Flecker, Alexander S -- Hall, Robert O Jr -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):833-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology and Physiology, University of Wyoming, Laramie, WY 82071, USA. brad.taylor@dartmouth.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902137" target="_blank"〉PubMed〈/a〉

    Fish population and behavior revealed by instantaneous continental shelf-scale imaging (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-04
    Description: Until now, continental shelf environments have been monitored with highly localized line-transect methods from slow-moving research vessels. These methods significantly undersample fish populations in time and space, leaving an incomplete and ambiguous record of abundance and behavior. We show that fish populations in continental shelf environments can be instantaneously imaged over thousands of square kilometers and continuously monitored by a remote sensing technique in which the ocean acts as an acoustic waveguide. The technique has revealed the instantaneous horizontal structural characteristics and volatile short-term behavior of very large fish shoals, containing tens of millions of fish and stretching for many kilometers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makris, Nicholas C -- Ratilal, Purnima -- Symonds, Deanelle T -- Jagannathan, Srinivasan -- Lee, Sunwoong -- Nero, Redwood W -- New York, N.Y. -- Science. 2006 Feb 3;311(5761):660-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Ocean Science and Engineering, Department of Mechanical Engineering, 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/16456080" target="_blank"〉PubMed〈/a〉

    Planktonic foraminifera of the California Current reflect 20th-century warming (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-10
    Description: It is currently unclear whether observed pelagic ecosystem responses to ocean warming, such as a mid-1970s change in the eastern North Pacific, depart from typical ocean variability. We report variations in planktonic foraminifera from varved sediments off southern California spanning the past 1400 years. Increasing abundances of tropical/subtropical species throughout the 20th century reflect a warming trend superimposed on decadal-scale fluctuations. Decreasing abundances of temperate/subpolar species in the late 20th century indicate a deep, penetrative warming not observed in previous centuries. These results imply that 20th-century warming, apparently anthropogenic, has already affected lower trophic levels of the California Current.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Field, David B -- Baumgartner, Timothy R -- Charles, Christopher D -- Ferreira-Bartrina, Vicente -- Ohman, Mark D -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):63-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA 92093, USA. dfield@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400144" target="_blank"〉PubMed〈/a〉

    Going east: new genetic and archaeological perspectives on the modern human colonization of Eurasia (2006)

    Details
    Publication Date: 2006-08-12
    Description: The pattern of dispersal of biologically and behaviorally modern human populations from their African origins to the rest of the occupied world between approximately 60,000 and 40,000 years ago is at present a topic of lively debate, centering principally on the issue of single versus multiple dispersals. Here I argue that the archaeological and genetic evidence points to a single successful dispersal event, which took genetically and culturally modern populations fairly rapidly across southern and southeastern Asia into Australasia, and with only a secondary and later dispersal into Europe.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mellars, Paul -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):796-800.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Archaeology, Cambridge University, Cambridge CB2 3DZ, UK. pam59@cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902130" target="_blank"〉PubMed〈/a〉

    Description: Easter Island (Rapa Nui) provides a model of human-induced environmental degradation. A reliable chronology is central to understanding the cultural, ecological, and demographic processes involved. Radiocarbon dates for the earliest stratigraphic layers at Anakena, Easter Island, and analysis of previous radiocarbon dates imply that the island was colonized late, about 1200 A.D. Substantial ecological impacts and major cultural investments in monumental architecture and statuary thus began soon after initial settlement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hunt, Terry L -- Lipo, Carl P -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1603-6.

    From individual dispersal to species ranges: perspectives for a changing world (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-12
    Description: Dispersal is often risky to the individual, yet the long-term survival of populations depends on having a sufficient number of individuals that move, find each other, and locate suitable breeding habitats. This tension has consequences that rarely meet our conservation or management goals. This is particularly true in changing environments, which makes the study of dispersal urgently topical in a world plagued with habitat loss, climate change, and species introductions. Despite the difficulty of tracking mobile individuals over potentially vast ranges, recent research has revealed a multitude of ways in which dispersal evolution can either constrain, or accelerate, species' responses to environmental changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kokko, Hanna -- Lopez-Sepulcre, Andres -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):789-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Ecological and Evolutionary Dynamics, Department of Biological and Environmental Science, University of Helsinki, Post Office Box 65 (Viikinkaari 1), FIN-00014 Helsinki, Finland. hanna.kokko@helsinki.fi〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902127" target="_blank"〉PubMed〈/a〉

    Biomass, size, and trophic status of top predators in the Pacific Ocean (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-16
    Description: Fisheries have removed at least 50 million tons of tuna and other top-level predators from the Pacific Ocean pelagic ecosystem since 1950, leading to concerns about a catastrophic reduction in population biomass and the collapse of oceanic food chains. We analyzed all available data from Pacific tuna fisheries for 1950-2004 to provide comprehensive estimates of fishery impacts on population biomass and size structure. Current biomass ranges among species from 36 to 91% of the biomass predicted in the absence of fishing, a level consistent with or higher than standard fisheries management targets. Fish larger than 175 centimeters fork length have decreased from 5% to approximately 1% of the total population. The trophic level of the catch has decreased slightly, but there is no detectable decrease in the trophic level of the population. These results indicate substantial, though not catastrophic, impacts of fisheries on these top-level predators and minor impacts on the ecosystem in the Pacific Ocean.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sibert, John -- Hampton, John -- Kleiber, Pierre -- Maunder, Mark -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1773-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joint Institute for Marine and Atmospheric Research, University of Hawaii, Honolulu, HI 96822, USA. sibert@hawaii.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170304" target="_blank"〉PubMed〈/a〉

Synoptic multiple-indicator views for major time slices demonstrate the transition from initial settlement after the sudden onset of humid conditions at 8500 B.C.E. to the exodus resulting from gradual desiccation since 5300 B.C.E. Southward shifting of the desert margin helped trigger the emergence of pharaonic civilization along the Nile, influenced the spread of pastoralism throughout the continent, and affects sub-Saharan Africa to the present day.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuper, Rudolph -- Kropelin, Stefan -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):803-7.

    A virus reveals population structure and recent demographic history of its carnivore host (2006)

    Details
    Publication Date: 2006-01-28
    Description: Directly transmitted parasites often provide substantial information about the temporal and spatial characteristics of host-to-host contact. Here, we demonstrate that a fast-evolving virus (feline immunodeficiency virus, FIV) can reveal details of the contemporary population structure and recent demographic history of its natural wildlife host (Puma concolor) that were not apparent from host genetic data and would be impossible to obtain by other means. We suggest that rapidly evolving pathogens may provide a complementary tool for studying population dynamics of their hosts in "shallow" time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biek, Roman -- Drummond, Alexei J -- Poss, Mary -- New York, N.Y. -- Science. 2006 Jan 27;311(5760):538-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wildlife Biology Program, University of Montana, Missoula, MT 59812, USA. rbiek@emory.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16439664" target="_blank"〉PubMed〈/a〉

    Out of the tropics: evolutionary dynamics of the latitudinal diversity gradient (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-07
    Description: The evolutionary dynamics underlying the latitudinal gradient in biodiversity have been controversial for over a century. Using a spatially explicit approach that incorporates not only origination and extinction but immigration, a global analysis of genera and subgenera of marine bivalves over the past 11 million years supports an "out of the tropics" model, in which taxa preferentially originate in the tropics and expand toward the poles without losing their tropical presence. The tropics are thus both a cradle and a museum of biodiversity, contrary to the conceptual dichotomy dominant since 1974; a tropical diversity crisis would thus have profound evolutionary effects at all latitudes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jablonski, David -- Roy, Kaustuv -- Valentine, James W -- New York, N.Y. -- Science. 2006 Oct 6;314(5796):102-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geophysical Sciences, University of Chicago, 5734 South Ellis Avenue, Chicago, IL 60637, USA. djablons@uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17023653" target="_blank"〉PubMed〈/a〉

    Parallel declines in pollinators and insect-pollinated plants in Britain and the Netherlands (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-22
    Description: Despite widespread concern about declines in pollination services, little is known about the patterns of change in most pollinator assemblages. By studying bee and hoverfly assemblages in Britain and the Netherlands, we found evidence of declines (pre-versus post-1980) in local bee diversity in both countries; however, divergent trends were observed in hoverflies. Depending on the assemblage and location, pollinator declines were most frequent in habitat and flower specialists, in univoltine species, and/or in nonmigrants. In conjunction with this evidence, outcrossing plant species that are reliant on the declining pollinators have themselves declined relative to other plant species. Taken together, these findings strongly suggest a causal connection between local extinctions of functionally linked plant and pollinator species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biesmeijer, J C -- Roberts, S P M -- Reemer, M -- Ohlemuller, R -- Edwards, M -- Peeters, T -- Schaffers, A P -- Potts, S G -- Kleukers, R -- Thomas, C D -- Settele, J -- Kunin, W E -- New York, N.Y. -- Science. 2006 Jul 21;313(5785):351-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Integrative and Comparative Biology and Earth and Biosphere Institute, University of Leeds, Leeds, LS2 9JT, UK. j.c.biesmeijer@leeds.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16857940" target="_blank"〉PubMed〈/a〉

    Thrice out of Africa: ancient and recent expansions of the honey bee, Apis mellifera (2006)

    Details
    Publication Date: 2006-10-28
    Description: We characterized Apis mellifera in both native and introduced ranges using 1136 single-nucleotide polymorphisms genotyped in 341 individuals. Our results indicate that A. mellifera originated in Africa and expanded into Eurasia at least twice, resulting in populations in eastern and western Europe that are geographically close but genetically distant. A third expansion in the New World has involved the near-replacement of previously introduced "European" honey bees by descendants of more recently introduced A. m. scutellata ("African" or "killer" bees). Our analyses of spatial transects and temporal series in the New World revealed differential replacement of alleles derived from eastern versus western Europe, with admixture evident in all individuals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitfield, Charles W -- Behura, Susanta K -- Berlocher, Stewart H -- Clark, Andrew G -- Johnston, J Spencer -- Sheppard, Walter S -- Smith, Deborah R -- Suarez, Andrew V -- Weaver, Daniel -- Tsutsui, Neil D -- New York, N.Y. -- Science. 2006 Oct 27;314(5799):642-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, University of Illinois at Urbana-Champaign, 505 South Goodwin Avenue, IL 61801, USA. charlie@life.uiuc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17068261" target="_blank"〉PubMed〈/a〉

    What is natural? The need for a long-term perspective in biodiversity conservation (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-25
    Description: Ecosystems change in response to factors such as climate variability, invasions, and wildfires. Most records used to assess such change are based on short-term ecological data or satellite imagery spanning only a few decades. In many instances it is impossible to disentangle natural variability from other, potentially significant trends in these records, partly because of their short time scale. We summarize recent studies that show how paleoecological records can be used to provide a longer temporal perspective to address specific conservation issues relating to biological invasions, wildfires, climate change, and determination of natural variability. The use of such records can reduce much of the uncertainty surrounding the question of what is "natural" and thereby start to provide important guidance for long-term management and conservation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willis, K J -- Birks, H J B -- New York, N.Y. -- Science. 2006 Nov 24;314(5803):1261-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Long-Term Ecology Laboratory, Oxford University Centre for the Environment, South Parks Road, Oxford OX1 3QY, UK. kathy.willis@ouce.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17124315" target="_blank"〉PubMed〈/a〉

    Fishing, trophic cascades, and the process of grazing on coral reefs (2006)

    Details
    Publication Date: 2006-01-10
    Description: Since the mass mortality of the urchin Diadema antillarum in 1983, parrotfishes have become the dominant grazer on Caribbean reefs. The grazing capacity of these fishes could be impaired if marine reserves achieve their long-term goal of restoring large consumers, several of which prey on parrotfishes. Here we compare the negative impacts of enhanced predation with the positive impacts of reduced fishing mortality on parrotfishes inside reserves. Because large-bodied parrotfishes escape the risk of predation from a large piscivore (the Nassau grouper), the predation effect reduced grazing by only 4 to 8%. This impact was overwhelmed by the increase in density of large parrotfishes, resulting in a net doubling of grazing. Increased grazing caused a fourfold reduction in the cover of macroalgae, which, because they are the principal competitors of corals, highlights the potential importance of reserves for coral reef resilience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mumby, Peter J -- Dahlgren, Craig P -- Harborne, Alastair R -- Kappel, Carrie V -- Micheli, Fiorenza -- Brumbaugh, Daniel R -- Holmes, Katherine E -- Mendes, Judith M -- Broad, Kenneth -- Sanchirico, James N -- Buch, Kevin -- Box, Steve -- Stoffle, Richard W -- Gill, Andrew B -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):98-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marine Spatial Ecology Lab, School of BioSciences, University of Exeter, Prince of Wales Road, Exeter EX4 4PS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400152" target="_blank"〉PubMed〈/a〉

    Impacts of biodiversity loss on ocean ecosystem services (2006)

    Publication Date: 2006-11-04
    Description: Human-dominated marine ecosystems are experiencing accelerating loss of populations and species, with largely unknown consequences. We analyzed local experiments, long-term regional time series, and global fisheries data to test how biodiversity loss affects marine ecosystem services across temporal and spatial scales. Overall, rates of resource collapse increased and recovery potential, stability, and water quality decreased exponentially with declining diversity. Restoration of biodiversity, in contrast, increased productivity fourfold and decreased variability by 21%, on average. We conclude that marine biodiversity loss is increasingly impairing the ocean's capacity to provide food, maintain water quality, and recover from perturbations. Yet available data suggest that at this point, these trends are still reversible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worm, Boris -- Barbier, Edward B -- Beaumont, Nicola -- Duffy, J Emmett -- Folke, Carl -- Halpern, Benjamin S -- Jackson, Jeremy B C -- Lotze, Heike K -- Micheli, Fiorenza -- Palumbi, Stephen R -- Sala, Enric -- Selkoe, Kimberley A -- Stachowicz, John J -- Watson, Reg -- New York, N.Y. -- Science. 2006 Nov 3;314(5800):787-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Dalhousie University, Halifax, NS, Canada B3H 4J1. bworm@dal.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17082450" target="_blank"〉PubMed〈/a〉

    Evolution of character displacement in Darwin's finches (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-15
    Description: Competitor species can have evolutionary effects on each other that result in ecological character displacement; that is, divergence in resource-exploiting traits such as jaws and beaks. Nevertheless, the process of character displacement occurring in nature, from the initial encounter of competitors to the evolutionary change in one or more of them, has not previously been investigated. Here we report that a Darwin's finch species (Geospiza fortis) on an undisturbed Galapagos island diverged in beak size from a competitor species (G. magnirostris) 22 years after the competitor's arrival, when they jointly and severely depleted the food supply. The observed evolutionary response to natural selection was the strongest recorded in 33 years of study, and close to the value predicted from the high heritability of beak size. These findings support the role of competition in models of community assembly, speciation, and adaptive radiations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grant, Peter R -- Grant, B Rosemary -- New York, N.Y. -- Science. 2006 Jul 14;313(5784):224-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544-1003, USA. prgrant@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16840700" target="_blank"〉PubMed〈/a〉

    Depletion, degradation, and recovery potential of estuaries and coastal seas (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-24
    Description: Estuarine and coastal transformation is as old as civilization yet has dramatically accelerated over the past 150 to 300 years. Reconstructed time lines, causes, and consequences of change in 12 once diverse and productive estuaries and coastal seas worldwide show similar patterns: Human impacts have depleted 〉90% of formerly important species, destroyed 〉65% of seagrass and wetland habitat, degraded water quality, and accelerated species invasions. Twentieth-century conservation efforts achieved partial recovery of upper trophic levels but have so far failed to restore former ecosystem structure and function. Our results provide detailed historical baselines and quantitative targets for ecosystem-based management and marine conservation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lotze, Heike K -- Lenihan, Hunter S -- Bourque, Bruce J -- Bradbury, Roger H -- Cooke, Richard G -- Kay, Matthew C -- Kidwell, Susan M -- Kirby, Michael X -- Peterson, Charles H -- Jackson, Jeremy B C -- New York, N.Y. -- Science. 2006 Jun 23;312(5781):1806-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, Dalhousie University, 1355 Oxford Street, Halifax, NS, Canada B3H 4J1. hlotze@dal.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16794081" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-02-25
    Description: Stochasticity in time series explains concave responses of per capita growth rate to population size. The gradients with the natural log of population size have more biological importance because they measure strength of density compensation. Its weakening with increasing body size across taxa (Sibly et al., Reports, 22 July 2005, p. 607) is consistent with slower responses in ascent than descent toward carrying capacity. Time series therefore suggest that populations of large-bodied animals underfill their environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doncaster, C Patrick -- New York, N.Y. -- Science. 2006 Feb 24;311(5764):1100; author reply 1100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, University of Southampton, Bassett Crescent East, Southampton SO16 7PX, UK. cpd@soton.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16497917" target="_blank"〉PubMed〈/a〉

    Effective enforcement in a conservation area (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-25
    Description: Wildlife within protected areas is under increasing threat from bushmeat and illegal trophy trades, and many argue that enforcement within protected areas is not sufficient to protect wildlife. We examined 50 years of records from Serengeti National Park in Tanzania and calculated the history of illegal harvest and enforcement by park authorities. We show that a precipitous decline in enforcement in 1977 resulted in a large increase in poaching and decline of many species. Conversely, expanded budgets and antipoaching patrols since the mid-1980s have greatly reduced poaching and allowed populations of buffalo, elephants, and rhinoceros to rebuild.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hilborn, Ray -- Arcese, Peter -- Borner, Markus -- Hando, Justin -- Hopcraft, Grant -- Loibooki, Martin -- Mduma, Simon -- Sinclair, Anthony R E -- New York, N.Y. -- Science. 2006 Nov 24;314(5803):1266.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Aquatic and Fishery Sciences, Box 355020, University of Washington, Seattle, WA 98195, USA. rayh@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17124316" target="_blank"〉PubMed〈/a〉

    Description: Sibly et al.'s (Reports, 22 July 2005, p. 607) contention that density dependence acts strongly on low-density animal populations irrespective of body size contradicts many long-term studies of large mammals. Their findings were distorted by harvest records, which may poorly reflect population trend. Omitting unreliable data, their massive data set is reduced to only one case for large mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peacock, Elizabeth -- Garshelis, David L -- New York, N.Y. -- Science. 2006 Jul 7;313(5783):45; author reply 45.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Nevada-Reno, Reno, NV 89557, USA. epeacock@gov.nu.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16825552" target="_blank"〉PubMed〈/a〉

    ENSO as an integrating concept in earth science (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-16
    Description: The El Nino-Southern Oscillation (ENSO) cycle of alternating warm El Nino and cold La Nina events is the dominant year-to-year climate signal on Earth. ENSO originates in the tropical Pacific through interactions between the ocean and the atmosphere, but its environmental and socioeconomic impacts are felt worldwide. Spurred on by the powerful 1997-1998 El Nino, efforts to understand the causes and consequences of ENSO have greatly expanded in the past few years. These efforts reveal the breadth of ENSO's influence on the Earth system and the potential to exploit its predictability for societal benefit. However, many intertwined issues regarding ENSO dynamics, impacts, forecasting, and applications remain unresolved. Research to address these issues will not only lead to progress across a broad range of scientific disciplines but also provide an opportunity to educate the public and policy makers about the importance of climate variability and change in the modern world.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McPhaden, Michael J -- Zebiak, Stephen E -- Glantz, Michael H -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1740-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉NOAA/Pacific Marine Environmental Laboratory, Seattle, WA, USA. michael.j.mcphaden@noaa.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170296" target="_blank"〉PubMed〈/a〉

    Ecological role of purple sea urchins (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-11
    Description: Sea urchins are major components of marine communities. Their grazing limits algal biomass, and they are preyed upon by many predators. Purple sea urchins (Strongylocentrotus purpuratus) are among the best studied species. They live in environments that alternate between two stable states: luxuriant, species-rich kelp forests and sea urchin-dominated "barrens." The transition from one state to the other can be initiated by several factors, including the abundance of algal food, predators, storm intensities, and incidence of disease. Purple sea urchins compete with other grazers, some of which are important fishery resources (such as abalones and red sea urchins), and they are harvested for scientific research. Revelations from their genome will lead to a better understanding of how they maintain their ecological importance, and may in turn enhance their economic potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pearse, John S -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):940-1.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Long Marine Laboratory, University of California, Santa Cruz, 100 Shaffer Road, Santa Cruz, CA 95060, USA. pearse@biology.ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17095690" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2006-02-18
    Description: Data that can be described by a power function are ubiquitous in nature. Although there is consensus that such data frequently emerge generally from nonlinear complex systems, a variety of specific mechanisms may be responsible for creating the pattern in particular cases. Here, we report on the distribution of a scale insect (Coccus viridis) that is a common agricultural pest. Its distribution in an organic coffee farm in southern Mexico generally follows a power function, but there are subtle deviations from that function. We offer a biological explanation for both adherence to the power functions and associated deviations, along with supporting evidence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vandermeer, John -- Perfecto, Ivette -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):1000-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA. jvander@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484494" target="_blank"〉PubMed〈/a〉

    From plant traits to plant communities: a statistical mechanistic approach to biodiversity (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-07
    Description: We developed a quantitative method, analogous to those used in statistical mechanics, to predict how biodiversity will vary across environments, which plant species from a species pool will be found in which relative abundances in a given environment, and which plant traits determine community assembly. This provides a scaling from plant traits to ecological communities while bypassing the complications of population dynamics. Our method treats community development as a sorting process involving species that are ecologically equivalent except with respect to particular functional traits, which leads to a constrained random assembly of species; the relative abundance of each species adheres to a general exponential distribution as a function of its traits. Using data for eight functional traits of 30 herbaceous species and community-aggregated values of these traits in 12 sites along a 42-year chronosequence of secondary succession, we predicted 94% of the variance in the relative abundances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shipley, Bill -- Vile, Denis -- Garnier, Eric -- New York, N.Y. -- Science. 2006 Nov 3;314(5800):812-4.

    Publication Date: 2006-12-13
    Description: Over the past decade, the Zaire strain of Ebola virus (ZEBOV) has repeatedly emerged in Gabon and Congo. Each human outbreak has been accompanied by reports of gorilla and chimpanzee carcasses in neighboring forests, but both the extent of ape mortality and the causal role of ZEBOV have been hotly debated. Here, we present data suggesting that in 2002 and 2003 ZEBOV killed about 5000 gorillas in our study area. The lag between neighboring gorilla groups in mortality onset was close to the ZEBOV disease cycle length, evidence that group-to-group transmission has amplified gorilla die-offs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bermejo, Magdalena -- Rodriguez-Teijeiro, Jose Domingo -- Illera, German -- Barroso, Alex -- Vila, Carles -- Walsh, Peter D -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1564.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecosystemes Forestiers d'Afrique Centrale (ECOFAC), Box Postale 15115 Libreville, Gabon. magda_bermejo@yahoo.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158318" target="_blank"〉PubMed〈/a〉
