    Description: Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffmann, Michael -- Hilton-Taylor, Craig -- Angulo, Ariadne -- Bohm, Monika -- Brooks, Thomas M -- Butchart, Stuart H M -- Carpenter, Kent E -- Chanson, Janice -- Collen, Ben -- Cox, Neil A -- Darwall, William R T -- Dulvy, Nicholas K -- Harrison, Lucy R -- Katariya, Vineet -- Pollock, Caroline M -- Quader, Suhel -- Richman, Nadia I -- Rodrigues, Ana S L -- Tognelli, Marcelo F -- Vie, Jean-Christophe -- Aguiar, John M -- Allen, David J -- Allen, Gerald R -- Amori, Giovanni -- Ananjeva, Natalia B -- Andreone, Franco -- Andrew, Paul -- Aquino Ortiz, Aida Luz -- Baillie, Jonathan E M -- Baldi, Ricardo -- Bell, Ben D -- Biju, S D -- Bird, Jeremy P -- Black-Decima, Patricia -- Blanc, J Julian -- Bolanos, Federico -- Bolivar-G, Wilmar -- Burfield, Ian J -- Burton, James A -- Capper, David R -- Castro, Fernando -- Catullo, Gianluca -- Cavanagh, Rachel D -- Channing, Alan -- Chao, Ning Labbish -- Chenery, Anna M -- Chiozza, Federica -- Clausnitzer, Viola -- Collar, Nigel J -- Collett, Leah C -- Collette, Bruce B -- Cortez Fernandez, Claudia F -- Craig, Matthew T -- Crosby, Michael J -- Cumberlidge, Neil -- Cuttelod, Annabelle -- Derocher, Andrew E -- Diesmos, Arvin C -- Donaldson, John S -- Duckworth, J W -- Dutson, Guy -- Dutta, S K -- Emslie, Richard H -- Farjon, Aljos -- Fowler, Sarah -- Freyhof, Jorg -- Garshelis, David L -- Gerlach, Justin -- Gower, David J -- Grant, Tandora D -- Hammerson, Geoffrey A -- Harris, Richard B -- Heaney, Lawrence R -- Hedges, S Blair -- Hero, Jean-Marc -- Hughes, Baz -- Hussain, Syed Ainul -- Icochea M, Javier -- Inger, Robert F -- Ishii, Nobuo -- Iskandar, Djoko T -- Jenkins, Richard K B -- Kaneko, Yoshio -- Kottelat, Maurice -- Kovacs, Kit M -- Kuzmin, Sergius L -- La Marca, Enrique -- Lamoreux, John F -- Lau, Michael W N -- Lavilla, Esteban O -- Leus, Kristin -- Lewison, Rebecca L -- Lichtenstein, Gabriela -- Livingstone, Suzanne R -- Lukoschek, Vimoksalehi -- Mallon, David P -- McGowan, Philip J K -- McIvor, Anna -- Moehlman, Patricia D -- Molur, Sanjay -- Munoz Alonso, Antonio -- Musick, John A -- Nowell, Kristin -- Nussbaum, Ronald A -- Olech, Wanda -- Orlov, Nikolay L -- Papenfuss, Theodore J -- Parra-Olea, Gabriela -- Perrin, William F -- Polidoro, Beth A -- Pourkazemi, Mohammad -- Racey, Paul A -- Ragle, James S -- Ram, Mala -- Rathbun, Galen -- Reynolds, Robert P -- Rhodin, Anders G J -- Richards, Stephen J -- Rodriguez, Lily O -- Ron, Santiago R -- Rondinini, Carlo -- Rylands, Anthony B -- Sadovy de Mitcheson, Yvonne -- Sanciangco, Jonnell C -- Sanders, Kate L -- Santos-Barrera, Georgina -- Schipper, Jan -- Self-Sullivan, Caryn -- Shi, Yichuan -- Shoemaker, Alan -- Short, Frederick T -- Sillero-Zubiri, Claudio -- Silvano, Debora L -- Smith, Kevin G -- Smith, Andrew T -- Snoeks, Jos -- Stattersfield, Alison J -- Symes, Andrew J -- Taber, Andrew B -- Talukdar, Bibhab K -- Temple, Helen J -- Timmins, Rob -- Tobias, Joseph A -- Tsytsulina, Katerina -- Tweddle, Denis -- Ubeda, Carmen -- Valenti, Sarah V -- van Dijk, Peter Paul -- Veiga, Liza M -- Veloso, Alberto -- Wege, David C -- Wilkinson, Mark -- Williamson, Elizabeth A -- Xie, Feng -- Young, Bruce E -- Akcakaya, H Resit -- Bennun, Leon -- Blackburn, Tim M -- Boitani, Luigi -- Dublin, Holly T -- da Fonseca, Gustavo A B -- Gascon, Claude -- Lacher, Thomas E Jr -- Mace, Georgina M -- Mainka, Susan A -- McNeely, Jeffery A -- Mittermeier, Russell A -- Reid, Gordon McGregor -- Rodriguez, Jon Paul -- Rosenberg, Andrew A -- Samways, Michael J -- Smart, Jane -- Stein, Bruce A -- Stuart, Simon N -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1503-9. doi: 10.1126/science.1194442.

    Description: The biogeochemical cycles of carbon (C), nitrogen (N) and phosphorus (P) are interlinked by primary production, respiration and decomposition in terrestrial ecosystems. It has been suggested that the C, N and P cycles could become uncoupled under rapid climate change because of the different degrees of control exerted on the supply of these elements by biological and geochemical processes. Climatic controls on biogeochemical cycles are particularly relevant in arid, semi-arid and dry sub-humid ecosystems (drylands) because their biological activity is mainly driven by water availability. The increase in aridity predicted for the twenty-first century in many drylands worldwide may therefore threaten the balance between these cycles, differentially affecting the availability of essential nutrients. Here we evaluate how aridity affects the balance between C, N and P in soils collected from 224 dryland sites from all continents except Antarctica. We find a negative effect of aridity on the concentration of soil organic C and total N, but a positive effect on the concentration of inorganic P. Aridity is negatively related to plant cover, which may favour the dominance of physical processes such as rock weathering, a major source of P to ecosystems, over biological processes that provide more C and N, such as litter decomposition. Our findings suggest that any predicted increase in aridity with climate change will probably reduce the concentrations of N and C in global drylands, but increase that of P. These changes would uncouple the C, N and P cycles in drylands and could negatively affect the provision of key services provided by these ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Delgado-Baquerizo, Manuel -- Maestre, Fernando T -- Gallardo, Antonio -- Bowker, Matthew A -- Wallenstein, Matthew D -- Quero, Jose Luis -- Ochoa, Victoria -- Gozalo, Beatriz -- Garcia-Gomez, Miguel -- Soliveres, Santiago -- Garcia-Palacios, Pablo -- Berdugo, Miguel -- Valencia, Enrique -- Escolar, Cristina -- Arredondo, Tulio -- Barraza-Zepeda, Claudia -- Bran, Donaldo -- Carreira, Jose Antonio -- Chaieb, Mohamed -- Conceicao, Abel A -- Derak, Mchich -- Eldridge, David J -- Escudero, Adrian -- Espinosa, Carlos I -- Gaitan, Juan -- Gatica, M Gabriel -- Gomez-Gonzalez, Susana -- Guzman, Elizabeth -- Gutierrez, Julio R -- Florentino, Adriana -- Hepper, Estela -- Hernandez, Rosa M -- Huber-Sannwald, Elisabeth -- Jankju, Mohammad -- Liu, Jushan -- Mau, Rebecca L -- Miriti, Maria -- Monerris, Jorge -- Naseri, Kamal -- Noumi, Zouhaier -- Polo, Vicente -- Prina, Anibal -- Pucheta, Eduardo -- Ramirez, Elizabeth -- Ramirez-Collantes, David A -- Romao, Roberto -- Tighe, Matthew -- Torres, Duilio -- Torres-Diaz, Cristian -- Ungar, Eugene D -- Val, James -- Wamiti, Wanyoike -- Wang, Deli -- Zaady, Eli -- England -- Nature. 2013 Oct 31;502(7473):672-6. doi: 10.1038/nature12670.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Departamento de Sistemas Fisicos, Quimicos y Naturales, Universidad Pablo de Olavide, Carretera de Utrera, kilometro 1, 41013 Sevilla, Spain [2] Area de Biodiversidad y Conservacion, Departamento de Biologia y Geologia, Escuela Superior de Ciencias Experimentales y Tecnologia, Universidad Rey Juan Carlos, Calle Tulipan Sin Numero, 28933 Mostoles, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24172979" target="_blank"〉PubMed〈/a〉

    Description: The ocean plays a critical role in supporting human well-being, from providing food, livelihoods and recreational opportunities to regulating the global climate. Sustainable management aimed at maintaining the flow of a broad range of benefits from the ocean requires a comprehensive and quantitative method to measure and monitor the health of coupled human-ocean systems. We created an index comprising ten diverse public goals for a healthy coupled human-ocean system and calculated the index for every coastal country. Globally, the overall index score was 60 out of 100 (range 36-86), with developed countries generally performing better than developing countries, but with notable exceptions. Only 5% of countries scored higher than 70, whereas 32% scored lower than 50. The index provides a powerful tool to raise public awareness, direct resource management, improve policy and prioritize scientific research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halpern, Benjamin S -- Longo, Catherine -- Hardy, Darren -- McLeod, Karen L -- Samhouri, Jameal F -- Katona, Steven K -- Kleisner, Kristin -- Lester, Sarah E -- O'Leary, Jennifer -- Ranelletti, Marla -- Rosenberg, Andrew A -- Scarborough, Courtney -- Selig, Elizabeth R -- Best, Benjamin D -- Brumbaugh, Daniel R -- Chapin, F Stuart -- Crowder, Larry B -- Daly, Kendra L -- Doney, Scott C -- Elfes, Cristiane -- Fogarty, Michael J -- Gaines, Steven D -- Jacobsen, Kelsey I -- Karrer, Leah Bunce -- Leslie, Heather M -- Neeley, Elizabeth -- Pauly, Daniel -- Polasky, Stephen -- Ris, Bud -- St Martin, Kevin -- Stone, Gregory S -- Sumaila, U Rashid -- Zeller, Dirk -- England -- Nature. 2012 Aug 30;488(7413):615-20. doi: 10.1038/nature11397.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Ecological Analysis and Synthesis, 735 State St Suite 300, Santa Barbara, California 93101, USA. halpern@nceas.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22895186" target="_blank"〉PubMed〈/a〉

    Description: For more than 30 years, the relationship between net primary productivity and species richness has generated intense debate in ecology about the processes regulating local diversity. The original view, which is still widely accepted, holds that the relationship is hump-shaped, with richness first rising and then declining with increasing productivity. Although recent meta-analyses questioned the generality of hump-shaped patterns, these syntheses have been criticized for failing to account for methodological differences among studies. We addressed such concerns by conducting standardized sampling in 48 herbaceous-dominated plant communities on five continents. We found no clear relationship between productivity and fine-scale (meters(-2)) richness within sites, within regions, or across the globe. Ecologists should focus on fresh, mechanistic approaches to understanding the multivariate links between productivity and richness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adler, Peter B -- Seabloom, Eric W -- Borer, Elizabeth T -- Hillebrand, Helmut -- Hautier, Yann -- Hector, Andy -- Harpole, W Stanley -- O'Halloran, Lydia R -- Grace, James B -- Anderson, T Michael -- Bakker, Jonathan D -- Biederman, Lori A -- Brown, Cynthia S -- Buckley, Yvonne M -- Calabrese, Laura B -- Chu, Cheng-Jin -- Cleland, Elsa E -- Collins, Scott L -- Cottingham, Kathryn L -- Crawley, Michael J -- Damschen, Ellen I -- Davies, Kendi F -- DeCrappeo, Nicole M -- Fay, Philip A -- Firn, Jennifer -- Frater, Paul -- Gasarch, Eve I -- Gruner, Daniel S -- Hagenah, Nicole -- Hille Ris Lambers, Janneke -- Humphries, Hope -- Jin, Virginia L -- Kay, Adam D -- Kirkman, Kevin P -- Klein, Julia A -- Knops, Johannes M H -- La Pierre, Kimberly J -- Lambrinos, John G -- Li, Wei -- MacDougall, Andrew S -- McCulley, Rebecca L -- Melbourne, Brett A -- Mitchell, Charles E -- Moore, Joslin L -- Morgan, John W -- Mortensen, Brent -- Orrock, John L -- Prober, Suzanne M -- Pyke, David A -- Risch, Anita C -- Schuetz, Martin -- Smith, Melinda D -- Stevens, Carly J -- Sullivan, Lauren L -- Wang, Gang -- Wragg, Peter D -- Wright, Justin P -- Yang, Louie H -- New York, N.Y. -- Science. 2011 Sep 23;333(6050):1750-3. doi: 10.1126/science.1204498.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Wildland Resources and the Ecology Center, Utah State University, 5230 Old Main, Logan, UT 84322, USA. peter.adler@usu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21940895" target="_blank"〉PubMed〈/a〉

    Description: We describe the draft genome of the microcrustacean Daphnia pulex, which is only 200 megabases and contains at least 30,907 genes. The high gene count is a consequence of an elevated rate of gene duplication resulting in tandem gene clusters. More than a third of Daphnia's genes have no detectable homologs in any other available proteome, and the most amplified gene families are specific to the Daphnia lineage. The coexpansion of gene families interacting within metabolic pathways suggests that the maintenance of duplicated genes is not random, and the analysis of gene expression under different environmental conditions reveals that numerous paralogs acquire divergent expression patterns soon after duplication. Daphnia-specific genes, including many additional loci within sequenced regions that are otherwise devoid of annotations, are the most responsive genes to ecological challenges.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3529199/" 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/PMC3529199/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Colbourne, John K -- Pfrender, Michael E -- Gilbert, Donald -- Thomas, W Kelley -- Tucker, Abraham -- Oakley, Todd H -- Tokishita, Shinichi -- Aerts, Andrea -- Arnold, Georg J -- Basu, Malay Kumar -- Bauer, Darren J -- Caceres, Carla E -- Carmel, Liran -- Casola, Claudio -- Choi, Jeong-Hyeon -- Detter, John C -- Dong, Qunfeng -- Dusheyko, Serge -- Eads, Brian D -- Frohlich, Thomas -- Geiler-Samerotte, Kerry A -- Gerlach, Daniel -- Hatcher, Phil -- Jogdeo, Sanjuro -- Krijgsveld, Jeroen -- Kriventseva, Evgenia V -- Kultz, Dietmar -- Laforsch, Christian -- Lindquist, Erika -- Lopez, Jacqueline -- Manak, J Robert -- Muller, Jean -- Pangilinan, Jasmyn -- Patwardhan, Rupali P -- Pitluck, Samuel -- Pritham, Ellen J -- Rechtsteiner, Andreas -- Rho, Mina -- Rogozin, Igor B -- Sakarya, Onur -- Salamov, Asaf -- Schaack, Sarah -- Shapiro, Harris -- Shiga, Yasuhiro -- Skalitzky, Courtney -- Smith, Zachary -- Souvorov, Alexander -- Sung, Way -- Tang, Zuojian -- Tsuchiya, Dai -- Tu, Hank -- Vos, Harmjan -- Wang, Mei -- Wolf, Yuri I -- Yamagata, Hideo -- Yamada, Takuji -- Ye, Yuzhen -- Shaw, Joseph R -- Andrews, Justen -- Crease, Teresa J -- Tang, Haixu -- Lucas, Susan M -- Robertson, Hugh M -- Bork, Peer -- Koonin, Eugene V -- Zdobnov, Evgeny M -- Grigoriev, Igor V -- Lynch, Michael -- Boore, Jeffrey L -- P42 ES004699/ES/NIEHS NIH HHS/ -- P42 ES004699-25/ES/NIEHS NIH HHS/ -- P42ES004699/ES/NIEHS NIH HHS/ -- R01 ES019324/ES/NIEHS NIH HHS/ -- R24 GM078274/GM/NIGMS NIH HHS/ -- R24 GM078274-01A1/GM/NIGMS NIH HHS/ -- R24GM07827401/GM/NIGMS NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2011 Feb 4;331(6017):555-61. doi: 10.1126/science.1197761.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genomics and Bioinformatics, Indiana University, 915 East Third Street, Bloomington, IN 47405, USA. jcolbour@indiana.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21292972" target="_blank"〉PubMed〈/a〉

    Description: Speciation generally involves a three-step process--range expansion, range fragmentation and the development of reproductive isolation between spatially separated populations. Speciation relies on cycling through these three steps and each may limit the rate at which new species form. We estimate phylogenetic relationships among all Himalayan songbirds to ask whether the development of reproductive isolation and ecological competition, both factors that limit range expansions, set an ultimate limit on speciation. Based on a phylogeny for all 358 species distributed along the eastern elevational gradient, here we show that body size and shape differences evolved early in the radiation, with the elevational band occupied by a species evolving later. These results are consistent with competition for niche space limiting species accumulation. Even the elevation dimension seems to be approaching ecological saturation, because the closest relatives both inside the assemblage and elsewhere in the Himalayas are on average separated by more than five million years, which is longer than it generally takes for reproductive isolation to be completed; also, elevational distributions are well explained by resource availability, notably the abundance of arthropods, and not by differences in diversification rates in different elevational zones. Our results imply that speciation rate is ultimately set by niche filling (that is, ecological competition for resources), rather than by the rate of acquisition of reproductive isolation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Price, Trevor D -- Hooper, Daniel M -- Buchanan, Caitlyn D -- Johansson, Ulf S -- Tietze, D Thomas -- Alstrom, Per -- Olsson, Urban -- Ghosh-Harihar, Mousumi -- Ishtiaq, Farah -- Gupta, Sandeep K -- Martens, Jochen -- Harr, Bettina -- Singh, Pratap -- Mohan, Dhananjai -- England -- Nature. 2014 May 8;509(7499):222-5. doi: 10.1038/nature13272.

    Description: Climate change is predicted to increase both drought frequency and duration, and when coupled with substantial warming, will establish a new hydroclimatological model for many regions. Large-scale, warm droughts have recently occurred in North America, Africa, Europe, Amazonia and Australia, resulting in major effects on terrestrial ecosystems, carbon balance and food security. Here we compare the functional response of above-ground net primary production to contrasting hydroclimatic periods in the late twentieth century (1975-1998), and drier, warmer conditions in the early twenty-first century (2000-2009) in the Northern and Southern Hemispheres. We find a common ecosystem water-use efficiency (WUE(e): above-ground net primary production/evapotranspiration) across biomes ranging from grassland to forest that indicates an intrinsic system sensitivity to water availability across rainfall regimes, regardless of hydroclimatic conditions. We found higher WUE(e) in drier years that increased significantly with drought to a maximum WUE(e) across all biomes; and a minimum native state in wetter years that was common across hydroclimatic periods. This indicates biome-scale resilience to the interannual variability associated with the early twenty-first century drought--that is, the capacity to tolerate low, annual precipitation and to respond to subsequent periods of favourable water balance. These findings provide a conceptual model of ecosystem properties at the decadal scale applicable to the widespread altered hydroclimatic conditions that are predicted for later this century. Understanding the hydroclimatic threshold that will break down ecosystem resilience and alter maximum WUE(e) may allow us to predict land-surface consequences as large regions become more arid, starting with water-limited, low-productivity grasslands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ponce Campos, Guillermo E -- Moran, M Susan -- Huete, Alfredo -- Zhang, Yongguang -- Bresloff, Cynthia -- Huxman, Travis E -- Eamus, Derek -- Bosch, David D -- Buda, Anthony R -- Gunter, Stacey A -- Scalley, Tamara Heartsill -- Kitchen, Stanley G -- McClaran, Mitchel P -- McNab, W Henry -- Montoya, Diane S -- Morgan, Jack A -- Peters, Debra P C -- Sadler, E John -- Seyfried, Mark S -- Starks, Patrick J -- England -- Nature. 2013 Feb 21;494(7437):349-52. doi: 10.1038/nature11836.

    Description: In 2002, world leaders committed, through the Convention on Biological Diversity, to achieve a significant reduction in the rate of biodiversity loss by 2010. We compiled 31 indicators to report on progress toward this target. Most indicators of the state of biodiversity (covering species' population trends, extinction risk, habitat extent and condition, and community composition) showed declines, with no significant recent reductions in rate, whereas indicators of pressures on biodiversity (including resource consumption, invasive alien species, nitrogen pollution, overexploitation, and climate change impacts) showed increases. Despite some local successes and increasing responses (including extent and biodiversity coverage of protected areas, sustainable forest management, policy responses to invasive alien species, and biodiversity-related aid), the rate of biodiversity loss does not appear to be slowing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butchart, Stuart H M -- Walpole, Matt -- Collen, Ben -- van Strien, Arco -- Scharlemann, Jorn P W -- Almond, Rosamunde E A -- Baillie, Jonathan E M -- Bomhard, Bastian -- Brown, Claire -- Bruno, John -- Carpenter, Kent E -- Carr, Genevieve M -- Chanson, Janice -- Chenery, Anna M -- Csirke, Jorge -- Davidson, Nick C -- Dentener, Frank -- Foster, Matt -- Galli, Alessandro -- Galloway, James N -- Genovesi, Piero -- Gregory, Richard D -- Hockings, Marc -- Kapos, Valerie -- Lamarque, Jean-Francois -- Leverington, Fiona -- Loh, Jonathan -- McGeoch, Melodie A -- McRae, Louise -- Minasyan, Anahit -- Hernandez Morcillo, Monica -- Oldfield, Thomasina E E -- Pauly, Daniel -- Quader, Suhel -- Revenga, Carmen -- Sauer, John R -- Skolnik, Benjamin -- Spear, Dian -- Stanwell-Smith, Damon -- Stuart, Simon N -- Symes, Andy -- Tierney, Megan -- Tyrrell, Tristan D -- Vie, Jean-Christophe -- Watson, Reg -- New York, N.Y. -- Science. 2010 May 28;328(5982):1164-8. doi: 10.1126/science.1187512.
