摘要

摘要黄颡鱼在亚马逊水生生态系统中发挥着重要的生态作用，对土著人民具有重要的文化和经济意义。由于该物种不存在空间生态学和运动数据，我们在2015年8月至2017年2月期间对纳波河中的63只个体进行了无线电跟踪。平均线性范围大小为16.2km（n = 31），平均家园面积为5.2平方公里（n = 27）。我们的研究结果是对统一P.unifilis的首次范围大小估计，并表明该物种可以被视为具有当地季节性运动的短距离兼性迁徙物种。

Space Use of Yellow-Spotted River Turtles (Podocnemis unifilis) in Yasuni National Park, Ecuador

Abstract The yellow-spotted river turtle (Podocnemis unifilis) plays ecological roles in the Amazonian aquatic ecosystem and has cultural and economic significance for indigenous peoples. Because spatial ecology and movement data are nonexistent for this species, we radio tracked 63 individuals in the Napo River between August 2015 and February 2017. Mean linear range size was 16.2 km (n = 31) and mean home range size was 5.2 km2 (n = 27). Our results are the first range size estimates for P. unifilis and suggest that the species could be treated as a short-distance facultative migrant with local seasonal movements.

期刊介绍： Chelonian Conservation and Biology is a biannual peer-reviewed journal of cosmopolitan and broad-based coverage of all aspects of conservation and biology of all chelonians, including freshwater turtles, marine turtles, and tortoises. Manuscripts may cover any aspects of turtle and tortoise research, with a preference for conservation or biology. Manuscripts dealing with conservation biology, systematic relationships, chelonian diversity, geographic distribution, natural history, ecology, reproduction, morphology and natural variation, population status, husbandry, community conservation initiatives, and human exploitation or conservation management issues are of special interest.
