9521077 Loiselle This Dissertation Enhancement award from the Americas Program, will support travel to Colombia by Mr. Luis M. Renjifo and his advisor, Dr. Bette A. Loiselle, to study the impact of forest fragmentation and the composition of the surrounding landscape matrix on populations of forest bird species. The primary objectives are to address the following major hypotheses: 1) the landscape matrix in which forests are embedded affect bird species composition of small, otherwise similar, forest areas; and 2) bird subgroups differ in their numerical responses to distinct surrounding landscape matrices. An experimental approach will be followed to test these hypotheses, taking advantage of current landscape conditions created by different land uses. Sampling units will be forest fragments within anthropogenic matrices and plots within continuous forests. A third objective will be to examine the historical change of bird assemblages in the study area following fragmentation. This will be done by comparing current species composition of the region's forest to species composition in the region prior to fragmentation, and with the non-fragmented area of study. ***

9521077 LOISELLE这项论文增强了美洲计划的奖项，将支持Luis M. Renjifo先生及其顾问Bette A. Loiselle博士前往哥伦比亚的旅行，以研究森林破碎的影响以及周围环境景观矩阵的组成森林鸟类种群。 主要目的是解决以下主要假设：1）嵌入森林会影响小，否则相似的森林地区的鸟类组成的景观基质； 2）鸟类亚组在数值响应中对周围景观矩阵的不同响应有所不同。 将采用实验方法来检验这些假设，利用当前的景观条件，由不同的土地用途产生。 采样单元将是人类基质中的森林碎片和连续森林中的地块。 第三个目标是检查分裂后研究区域中鸟类组合的历史变化。 这将通过将该地区森林的当前物种组成与分裂之前的物种组成以及未碎裂的研究领域进行比较。 ***
