Food Selectivity and Habitat Utilization by Introduced Trouts and Native Non-Game Fishes in Subalpine Lakes

MASTERS THESIS: By measuring food habits at a period of low resource availability, habitat distribution on a diel basis and the abundance of potential food sources, the researcher collected data on three of the essential elements needed to evaluate interspecific competition. Removal of the supposed competitive species and subsequent niche analysis remains as an additional important element.硕士学位论文：通过在资源可获得性较低的时期开展摄食习性调查、基于昼夜节律的栖息地分布观测以及潜在食物来源丰度测定，研究者收集了评估种间竞争所需的三项核心要素相关数据。移除疑似竞争物种并开展后续生态位分析，仍是另一项关键研究要素。
