Animal personality meets community ecology: founder species aggression and the dynamics of spider communities.

摘要: Silken web-reef created by the spider Anelosimus studiosus (main picture) and close-up (insert of multi-female, adult colony same species. (photographs: T. Jones, J. Pruitt A. Wild) In Focus: Pruitt, J.N. & Modlmeier, A.P. (2015) Animal personality in a foundation species drives community divergence collapse wild. Journal Ecology, 84 Interspecific interactions form cornerstone niche theory ecology. The 7-year study Focus here supports view that variation within could also be crucially important. Spider communities experimentally wild, with either aggressive or docile individuals founder species, were highly divergent patterns succession for several years. Eventually, they converged on composition only to entirely shortly after, apparently because specific mix aggression phenotypes between just before collapse. These results suggest numerous avenues research behavioural ecology evolutionary metapopulations, help resolve differences competing theories.
