摘要

世界上许多湖泊都有浮游生物群落,它们是由一种被称为大小选择性捕食的生态现象构成的。尺寸选择性捕食是捕食者选择特定尺寸的猎物的一种捕食形式。大小选择性捕食不仅影响湖泊生态系统中浮游动物种群的大小分布,而且影响浮游动物类群的组成。在这个实验中被问到的首要问题是,不同的浮游动物种群在它们遭受大小选择性捕食的条件下是如何受到影响的。在我们的研究中,我们评估了不列颠哥伦比亚省的两个湖泊中大小选择性捕食的影响,并在实验室中使用活的浮游动物和它们的捕食者来模拟自然界中的相互作用,重现了自然现象。

Size Selective Predation and its Effects on Zooplankton Populations
Many lakes around the world have plankton communities that are structured by an ecological phenomenon known as size selective predation. Size selective predation is a form of predation that selects for prey of a specific desired size by the predator. Size selective predation can have an effect on both size distribution of the prey population as well as the composition of zooplankton taxa in a lake ecosystem. The overarching question being asked in this experiment is how the different zooplankton populations are affected under conditions where they are subjected to size selective predation. Within our study, we assessed the effects of size selective predation in two lakes in British Columbia, and reproduced the natural phenomenon in the lab using live zooplankton and their predators to simulate interactions in the natural world.

期刊介绍: The vision of the Journal of Student Affairs Research and Practice (JSARP) is to publish the most rigorous, relevant, and well-respected research and practice making a difference in student affairs practice. JSARP especially encourages manuscripts that are unconventional in nature and that engage in methodological and epistemological extensions that transcend the boundaries of traditional research inquiries.
