    Rapid temporal reversal in predator-driven natural selection (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-18
    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〉

    Founder effects persist despite adaptive differentiation: a field experiment with lizards (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-02-04
    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.
