DISSERTATION RESEARCH Wildlife Poaching Seed

项目摘要

Wildlife poaching in tropical forests is widespread. Some of the animals that are illegally hunted provide critical seed dispersal services to plants, yet we have little understanding of how poaching indirectly influences plant populations. My research seeks to understand the relative importance of three species of seed dispersers -gibbons, sambar deer, and muntjac deer- to the population persistence of a dominant tropical tree, Choerospondias axillaris, in forests in Thailand. In my research, I am asking whether the three species of dispersers provide equal quality dispersal to C. axillaris. If this is the case, then reductions in the population size of one of these disperser species might be compensated for by the activities of the remaining species. Alternatively, if these species differ in the quality of dispersal services they provide, then reductions in the population size of one of these species could differentially impact tree persistence. Understanding the indirect effects of poaching on tree persistence is critical to determining whether activities such as wildlife harvest have ramifying effects through diverse systems that we are trying to protect. This is one of the first studies to compare the functional similarity of mammals with respect to the dissemination of seeds across different habitats, and will help us understand the seed dispersal mutualism and its susceptibility to anthropogenic disruption. This in turn will allow us to design conservation strategies based, not on single-species, but on the preservation of ecologically-crucial species interactions.

在热带森林中偷猎野生动物的现象十分普遍。一些被非法猎杀的动物为植物提供了重要的种子传播服务，但我们对偷猎如何间接影响植物种群知之甚少。我的研究旨在了解三种种子传播者的相对重要性-长臂猿，水鹿，和赤鹿-在泰国森林中占主导地位的热带树木，南酸枣的人口持续性。在我的研究中，我想知道这三种散布者是否提供了与C相同的散布质量。腋窝。如果是这样的话，那么其中一个扩散物种的种群规模的减少可能会被其余物种的活动所补偿。或者，如果这些物种的传播服务的质量不同，他们提供的，然后在这些物种之一的人口规模的减少可能会影响树木的持久性差异。了解偷猎对树木持久性的间接影响对于确定野生动物收获等活动是否会通过我们试图保护的各种系统产生衍生影响至关重要。这是比较哺乳动物在不同生境中传播种子的功能相似性的第一批研究之一，将有助于我们了解种子传播互利共生及其对人为干扰的敏感性。这反过来将使我们能够设计保护策略，而不是基于单一物种，而是基于保护生态关键物种的相互作用。
