项目摘要

Adaptive radiation, in which a clade diversifies from an ancestral form to produce descendants adapted to utilize a wide variety of ecological niches, has become a topic of great recent interest. The evolutionary radiation of Anolis lizards in the Caribbean has become a textbook case study of adaptive radiation, demonstrating that independent radiations can converge on very similar adaptive traits. This project expands this work to ask why in some cases evolutionary diversification yields very different results. On each island in the Greater Antilles, evolutionary radiation has occurred, producing species specialized to use different parts of the habitat (e.g., twigs, grass, canopy). Amazingly, evolution has occurred independently on each island, producing the same set of habitat specialists. Detailed analysis has indicated that strong relationships exist among species between anatomy and habitat use. Long-legged species occur on broad surfaces, for example, and more arboreal species have better developed toepads. Functional studies have explained these relationships by determining the relationship between morphology and functional performance capabilities, on one hand, and between performance abilities and habitat use and behavior, on the other. Anolis has also radiated widely in mainland Central and South America. Although less studied, these lizards have clearly evolved in different ways. Mainland anoles are as diverse among themselves as are island anoles, but the mainland species differ anatomically from the islands species. Most strikingly, the relationship between anatomy and habitat use differs fundamentally between mainland and island anoles.The PIs will investigate whether differences in the anatomy~ecology relationship result because the relationship between functional capabilities and ecology differ or because the relationship between anatomy and functional capabilities differs (or both). In addition, the PIs will seek explanations for the variation in anatomy~performance relationships between island and mainland lizards, focusing on the physiological properties of muscles. Jointly the data collected to address these goals will enable the PIs to address the question of why mainland anoles have radiated in fundamentally different ways than island anoles. Undergraduate students, including women and individuals from underrepresented groups, a postdoctoral fellow and foreign collaborators will receive unique interdisciplinary training. The PIs will work with the Harvard Museum of Natural History to develop an exhibit on Anolis as a model system for understanding how evolution works.
适应性辐射,其中一个分支从祖先的形式多样化,产生适应利用各种各样的生态位的后代,已成为一个非常感兴趣的话题。加勒比海的阿诺利斯蜥蜴的进化辐射已经成为适应辐射的教科书案例研究,表明独立的辐射可以收敛到非常相似的适应特征。这个项目扩展了这项工作,以询问为什么在某些情况下进化多样化会产生非常不同的结果。在大安的列斯群岛的每个岛屿上,都发生了进化辐射,产生了专门利用栖息地不同部分的物种(例如,树枝、草、树冠)。令人惊讶的是,进化在每个岛屿上独立发生,产生了相同的栖息地专家。 详细的分析表明,物种之间存在很强的关系解剖和栖息地的使用。 例如,长腿物种出现在宽阔的表面上,更多的树栖物种有更好的脚趾。 功能研究一方面通过确定形态与功能表现能力之间的关系,另一方面通过确定表现能力与栖息地利用和行为之间的关系来解释这些关系。安诺利斯也在中美洲和南美洲大陆广泛辐射。 虽然研究较少,但这些蜥蜴显然以不同的方式进化。大陆的变色龙和岛屿的变色龙一样具有多样性,但是大陆的变色龙和岛屿的变色龙在解剖学上不同。最引人注目的是,解剖学和栖息地利用之间的关系在大陆和岛屿anoles之间有根本的不同。PI将调查解剖学-生态学关系的差异是因为功能能力和生态学之间的关系不同还是因为解剖学和功能能力之间的关系不同(或两者兼而有之)。此外,PI将寻求解释岛屿和大陆蜥蜴之间的解剖-性能关系的变化,重点是肌肉的生理特性。共同收集的数据,以解决这些目标将使PI解决的问题,为什么大陆的变色龙辐射在根本上不同的方式比岛屿变色龙。本科生,包括妇女和来自代表性不足群体的个人,博士后研究员和外国合作者将接受独特的跨学科培训。PI将与哈佛自然历史博物馆合作,开发一个关于Anolis的展览,作为理解进化如何运作的模型系统。
