根据岛屿规则，由于岛屿上的食物资源和捕食者缺乏，大型物种的岛屿普遍进化趋势变得越来越小。已经广泛研究了岛上较小的身体大小的演变，但是在比较分析中，几乎没有做出分析该规则，以控制种内的系统发育相关性，或分析单个解剖学成分的变化，例如脑大小和颅骨学，随着体型的降低。我的论文工作探讨了整个东南亚的长尾猕猴之间的体型，大脑大小和头骨形状差异。在一种新颖的跨学科方法中，我结合了分子系统发育和经典的形态学和形态计量学分析，以全面分析该物种中的岛屿规则。
According to the Island Rule, there is a general evolutionary trend on islands for large-bodied species to become smaller due to a lack of food resources and predators on islands. Evolution of smaller body sizes on islands has been widely studied, but little work has been done to analyze this rule within species, to control for intraspecific phylogenetic relatedness in comparative analyses, or to analyze changes in individual anatomical components, such as brain size and cranial morphology, as body size decreases. My dissertation work explores body size, brain size and skull shape differences between insular and mainland individuals of long-tailed macaques throughout Southeast Asia. In a novel and cross-disciplinary approach, I combined molecular phylogenetics and classical morphological and morphometric analyses to comprehensively analyze the Island Rule in this species.
