The influence of geographic distance and environmental factors in the distribution of genotypic and phenotypic variation of the frog Atelopus manauensis (Bufonidae) in Central Amazonia

For the first aim - genotypic variation, we characterise genetic diversity and the environmental features associated to connectivity for a narrowly distributed and threatened Amazonian frog, Atelopus manauensis. Specifically, we (1) characterize genetic variation and identify genetically distinct parts of the distribution of A. manauensis; (2) search for evidence of localised adaptation; and (3) identify which landscape features influence functional and genetic connectivity. This study provides relevant information for effective conservation actions aiming at the protection of the studied species. Also, the present study uses a approach that migth guide future studies aiming at providing valuable information for species conservation in Tropical regions, where areas for conservation purposes are becaming scarce.

针对首个研究目标——基因型变异：我们对一种狭域分布且受威胁的亚马孙蛙类——马瑙斯丑角蛙（Atelopus manauensis）的遗传多样性及其与种群连通性相关的环境特征开展了表征分析。具体而言，本研究完成以下三项内容：（1）表征该蛙的遗传变异特征，并识别其分布区内遗传分化显著的区域；（2）搜寻局部适应的相关证据；（3）明确哪些景观特征会影响功能连通性与遗传连通性。本研究可为该研究物种的有效保护行动提供关键参考信息。此外，本研究所采用的研究方法可为未来旨在为热带地区物种保护提供宝贵信息的相关研究提供借鉴思路；鉴于当前热带地区保护用地日趋紧缺，此类研究对该区域的物种保护而言极具参考价值。
