    Description: Lizard and spider populations were censused immediately before and after Hurricane Lili on islands differentially affected by the storm surge. The results support three general propositions. First, the larger organisms, lizards, are more resistant to the immediate impact of moderate disturbance, whereas the more prolific spiders recover faster. Second, extinction risk is related to population size when disturbance is moderate but not when it is catastrophic. Third, after catastrophic disturbance, the recovery rate among different types of organisms is related to dispersal ability. The absence of the poorer dispersers, lizards, from many suitable islands is probably the result of long-lasting effects of catastrophes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spiller -- Losos -- Schoener -- New York, N.Y. -- Science. 1998 Jul 31;281(5377):695-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9685262" target="_blank"〉PubMed〈/a〉

    Description: We document the decimation and recovery of the commonest lizard species, Anolis sagrei, on 66 islands in the Bahamas that were directly hit by Hurricane Floyd in September 1999. Before the hurricane, an island's area was a better predictor of the occurrence of A. sagrei than was its altitude. Immediately after, altitude was a better predictor: Apparently all lizards on islands lower than about 3 meters maximum elevation perished in the storm surge. After about 1 year, area again became the better predictor. By 19 months after the hurricane, A. sagrei populations occurred on 88% of the islands they formerly occupied. Recovery occurred via overwater colonization and propagation from eggs that survived inundation, mechanisms that were enhanced by larger island area. Thus, natural processes first destroyed and then quickly restored a highly regular species-area distribution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoener, T W -- Spiller, D A -- Losos, J B -- New York, N.Y. -- Science. 2001 Nov 16;294(5546):1525-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Evolution and Ecology, University of California, Davis, CA 95616, USA. twschoener@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11711674" target="_blank"〉PubMed〈/a〉

    Description: Until recently, large apex consumers were ubiquitous across the globe and had been for millions of years. The loss of these animals may be humankind's most pervasive influence on nature. Although such losses are widely viewed as an ethical and aesthetic problem, recent research reveals extensive cascading effects of their disappearance in marine, terrestrial, and freshwater ecosystems worldwide. This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles. These findings emphasize the urgent need for interdisciplinary research to forecast the effects of trophic downgrading on process, function, and resilience in global ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Estes, James A -- Terborgh, John -- Brashares, Justin S -- Power, Mary E -- Berger, Joel -- Bond, William J -- Carpenter, Stephen R -- Essington, Timothy E -- Holt, Robert D -- Jackson, Jeremy B C -- Marquis, Robert J -- Oksanen, Lauri -- Oksanen, Tarja -- Paine, Robert T -- Pikitch, Ellen K -- Ripple, William J -- Sandin, Stuart A -- Scheffer, Marten -- Schoener, Thomas W -- Shurin, Jonathan B -- Sinclair, Anthony R E -- Soule, Michael E -- Virtanen, Risto -- Wardle, David A -- New York, N.Y. -- Science. 2011 Jul 15;333(6040):301-6. doi: 10.1126/science.1205106.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA 95060, USA. jestes@ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21764740" target="_blank"〉PubMed〈/a〉

    Description: Population phenomena, which provide much of the underlying basis for the theoretical structure of island biogeography, have received little direct study. We determined a key population trait-survival-in the Bahamian lizard Anolis sagrei on islands with an experimentally introduced predatory lizard and on neighboring unmanipulated islands. On unmanipulated islands, survival declined with several variables, most notably vegetation height: The island with the shortest vegetation had nearly the highest survival recorded for any lizard. On islands with the introduced predator, which forages mostly on the ground, A. sagrei shifted to taller vegetation; unlike on unmanipulated islands, its survival was very low on islands with the shortest vegetation but was higher on the others. Thus, species introduction radically changed a resident species' relation of survival to a key island-biogeographical variable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoener, Thomas W -- Losos, Jonathan B -- Spiller, David A -- New York, N.Y. -- Science. 2005 Dec 16;310(5755):1807-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Evolution and Ecology, University of California, Davis, CA 95616, USA. twschoener@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16357259" target="_blank"〉PubMed〈/a〉

    Description: To assay the effect of area and predators on invasion success, spiders were introduced onto islands that were large, with lizard predators; large, without lizard predators; or small, without lizard predators. Short-term survival was greater on islands without than with predators; area had no effect. Spiders initially increased substantially on both groups of islands without lizards, but after 5 years they nearly died off on small islands while persisting on most large islands; populations in the presence of predators never increased above initial sizes. Results show how predators as well as area are important in determining invasion success.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoener, T W -- Spiller, D A -- New York, N.Y. -- Science. 1995 Mar 24;267(5205):1811-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17775810" target="_blank"〉PubMed〈/a〉

    Description: As the environment changes, will species be able to adapt? By conducting experiments in natural environments, biologists can study how evolutionary processes such as natural selection operate through time. We predicted that the introduction of a terrestrial predator would first select for longer-legged lizards, which are faster, but as the lizards shifted onto high twigs to avoid the predator, selection would reverse toward favoring the shorter-legged individuals better able to locomote there. Our experimental studies on 12 islets confirmed these predictions within a single generation, thus demonstrating the rapidity with which evolutionary forces can change during times of environmental flux.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Losos, Jonathan B -- Schoener, Thomas W -- Langerhans, R Brian -- Spiller, David A -- New York, N.Y. -- Science. 2006 Nov 17;314(5802):1111.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Box 1137, Washington University, St. Louis, MO 63130 USA. jlosos@oeb.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17110568" target="_blank"〉PubMed〈/a〉

    Description: The effect of ecological change on evolution has long been a focus of scientific research. The reverse--how evolutionary dynamics affect ecological traits--has only recently captured our attention, however, with the realization that evolution can occur over ecological time scales. This newly highlighted causal direction and the implied feedback loop--eco-evolutionary dynamics--is invigorating both ecologists and evolutionists and blurring the distinction between them. Despite some recent relevant studies, the importance of the evolution-to-ecology pathway across systems is still unknown. Only an extensive research effort involving multiple experimental approaches-particularly long-term field experiments--over a variety of ecological communities will provide the answer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoener, Thomas W -- New York, N.Y. -- Science. 2011 Jan 28;331(6016):426-9. doi: 10.1126/science.1193954.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Evolution and Ecology, University of California, Davis, One Shields Avenue, Davis, CA 95616, USA. twschoener@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21273479" target="_blank"〉PubMed〈/a〉

    Description: The effect of environmental change on ecosystems is mediated by species interactions. Environmental change may remove or add species and shift life-history events, altering which species interact at a given time. However, environmental change may also reconfigure multispecies interactions when both species composition and phenology remain intact. In a Caribbean island system, a major manifestation of environmental change is seaweed deposition, which has been linked to eutrophication, overfishing, and hurricanes. Here, we show in a whole-island field experiment that without seaweed two predators--lizards and ants--had a substantially greater-than-additive effect on herbivory. When seaweed was added to mimic deposition by hurricanes, no interactive predator effect occurred. Thus environmental change can substantially restructure food-web interactions, complicating efforts to predict anthropogenic changes in ecosystem processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Piovia-Scott, Jonah -- Spiller, David A -- Schoener, Thomas W -- New York, N.Y. -- Science. 2011 Jan 28;331(6016):461-3. doi: 10.1126/science.1200282.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Evolution and Ecology and Center for Population Biology, One Shields Avenue, University of California Davis, Davis, CA 95616-8755, USA. jpioviascott@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21273487" target="_blank"〉PubMed〈/a〉

    Description: The extent to which random processes such as founder events contribute to evolutionary divergence is a long-standing controversy in evolutionary biology. To determine the respective contributions of founder effects and natural selection, we conducted an experiment in which brown anole (Anolis sagrei) lizard populations were established on seven small islands in the Bahamas, from male-female pairs randomly drawn from the same large-island source. These founding events generated significant among-island genetic and morphological differences that persisted throughout the course of the experiment despite all populations adapting in the predicted direction-shorter hindlimbs-in response to the narrower vegetation on the small islands. Thus, using a replicated experiment in nature, we showed that both founder effects and natural selection jointly determine trait values in these populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kolbe, Jason J -- Leal, Manuel -- Schoener, Thomas W -- Spiller, David A -- Losos, Jonathan B -- New York, N.Y. -- Science. 2012 Mar 2;335(6072):1086-9. doi: 10.1126/science.1209566.

    Description: Distributions and densities of orb spiders on small islands are extremely variable. Species occurrences are far more irregular for spiders than vertebrates on the same islands. Much variation in spider density is explainable by distance from the presumed source of colonists and presence or absence of vertebrate predators. As has been predicted for passive dispersers, densities decline exponentially with distance. For a given distance, spider densities are about ten times greater on islands without vertebrate predators than on those with such predators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoener, T W -- Toft, C A -- New York, N.Y. -- Science. 1983 Mar 18;219(4590):1353-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17735613" target="_blank"〉PubMed〈/a〉
