    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〉

    Description: Spatial self-organization is the main theoretical explanation for the global occurrence of regular or otherwise coherent spatial patterns in ecosystems. Using mussel beds as a model ecosystem, we provide an experimental demonstration of spatial self-organization. Under homogeneous laboratory conditions, mussels developed regular patterns, similar to those in the field. An individual-based model derived from our experiments showed that interactions between individuals explained the observed patterns. Furthermore, a field study showed that pattern formation affected ecosystem-level processes in terms of improved growth and resistance to wave action. Our results imply that spatial self-organization is an important determinant of the structure and functioning of ecosystems, and it needs to be considered in their conservation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van de Koppel, Johan -- Gascoigne, Joanna C -- Theraulaz, Guy -- Rietkerk, Max -- Mooij, Wolf M -- Herman, Peter M J -- D18866/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):739-42. doi: 10.1126/science.1163952.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Spatial Ecology Department, the Netherlands Institute of Ecology (NIOO-KNAW), Post Office Box 140, 4400 AC Yerseke, Netherlands.

    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: 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: Many top-predator fish stocks in both freshwater and marine systems have collapsed as a result of overharvesting. Consequently, some of these communities have shifted into seemingly irreversible new states. We showed, for predators feeding on prey that exhibit food-dependent growth, that culling of fish prey may promote predator recovery. We removed old stunted individuals of a prey-fish species in a large, low-productive lake, which caused an increase in the availability of small-sized prey and allowed the predator to recover. The shift in community state has been sustained for more than 15 years after the cull ended and represents an experimental demonstration of an alternative stable state in a large-scale field system. Because most animals exhibit food-dependent growth, shifts into alternative stable states resulting from overcompensating prey growth may be common in nature and may require counterintuitive management strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Persson, Lennart -- Amundsen, Per-Arne -- De Roos, Andre M -- Klemetsen, Anders -- Knudsen, Rune -- Primicerio, Raul -- New York, N.Y. -- Science. 2007 Jun 22;316(5832):1743-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Environmental Science, Umea University, S-901 87 Umea, Sweden. lennart.persson@emg.umu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17588929" target="_blank"〉PubMed〈/a〉

    Description: The role of behavioral mechanisms in animal invasions is poorly understood. We show that asymmetric mating interactions between closely related but previously allopatric genetic groups of the whitefly Bemisia tabaci, a haplodiploid species, have been a driving force contributing to widespread invasion and displacement by alien populations. We conducted long-term field surveys, caged population experiments, and detailed behavioral observations in Zhejiang, China, and Queensland, Australia, to investigate the invasion process and its underlying behavioral mechanisms. During invasion and displacement, we found increased frequency of copulation leading to increased production of female progeny among the invader, as well as reduced copulation and female production in the indigenous genetic groups. Such asymmetric mating interactions may be critical to determining the capacity of a haplodiploid invader and the consequences for its closely related indigenous organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Shu-Sheng -- De Barro, P J -- Xu, Jing -- Luan, Jun-Bo -- Zang, Lian-Sheng -- Ruan, Yong-Ming -- Wan, Fang-Hao -- New York, N.Y. -- Science. 2007 Dec 14;318(5857):1769-72.
