RUI: Intraguild Predation and Cannibalism Between Caddisflies in Subalpine Ponds

小行星9407856 越来越多的证据表明，生态学家对水生食物网结构的认识过于简单化。 最近有很多兴趣，但相对较少的数据对行会内捕食（IGP;即，（3）具有相似食性的物种相互捕食。 本研究项目的目标是确定的影响intraguild捕食和cannabalism之间的石蛾幼虫对成年健身，研究的近端机制，介导的IGP之间的石蛾，并量化的直接和间接的影响，其他无脊椎动物的捕食者和蝾螈对这些石蛾相互作用的结果。 这项研究将提供第一个数据内团捕食水生轮虫喂养的生物。 研究结果将提高我们对水生态系统功能的理解，并在水污染治理和水生态系统管理中具有应用价值。

Recently there has been much interest, but relatively little data on intraguild predation (IGP; i.e., predation of species with similar feeding habits on one another). The objectives of this research project are to determine the effects of intraguild predation and cannabalism among caddisfly larvae on adult fitness, study the proximate mechanisms that mediate IGP among caddisflies, and quantify the direct and indirect effects of other invertebrate predators and salamander on the outcome of these caddisfly interactions. This research will provide the first data on intraguild predation in aquatic detritis-feeding organisms. The results will improve our understanding of the functioning of aquatic ecosystems and have application in aquatic pollution abatement and management of aquatic ecosystems.
