龟类生态形态学研究进展

摘要： 龟类占据从水生到陆生的多样化生境，其形态迥异，是生态形态学研究的理想模型动物。研究表明，生态位分离（生境和食性的差异）是导致龟类形态变异的主要生态因素。本文从生态形态学的定义、龟类生态形态学特征与食性和生境之间的关联性以及其系统发育3个方面综述了龟类生态形态学的研究进展，并指出当前研究中存在诸如现实生态位研究缺乏、特化类群的生态学原因不明和生境分类主观而简单的问题，建议今后加强相关方面的研究，从而促进龟类形态变异的生态成因得到更加全面而深入的理解。

Abstract:

Turtles with different morphology occupy a wide range of habitats from aquatic to highly terrestrial, making them an ideal species group for ecomorphological study. Current studies indicate that niche divergence, including dietary and habitat shift, may be correlated with morphological differences of turtles. This review outlines the research progress on the ecomorphology of turtles, with the focus on the definitions, the relationships between ecomorphological characteristics (body size and morphology of shell, head, limbs and tail), feeding habits and habitat use. Meanwhile, the comparative analysis of phylogenetic systematics and ecomorphology of turtles was addressed in this paper. In addition, current issues in ecomorphological research were pointed out and some suggestions for the further work were made.
