This action funds an NSF Minority Postdoctoral Research Fellowship for FY 2009 and is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The fellowship supports a research and training plan at a host laboratory for the Fellow who also presents a plan to broaden participation in biology of underrepresented minorities. The title of the research and training plan for this fellowship to David Rodriguez is "Population genetics of Batrachochytrium dendrobatidis and New World amphibian declines." The host institution for this research is Cornell University and the sponsoring scientist is Dr. Kelly Zamudio.Amphibians are declining at an unprecedented rate contributing to a decrease in the earth's biodiversity, resulting in potentially dire consequences for ecosystems in which those species play critical roles. The chytrid fungus Batrachochytrium dendrobatidis (Bd)has been implicated in recent global amphibian declines. This project is investigating the population genetics of Bd in Central and South America to test two competing hypotheses that possibly explain the epidemic; namely, the climate-linked epidemic hypothesis and the spreading pathogen hypothesis.The training objectives are to further develop expertise in i) bioinformatics, ii) experimental laboratory techniques for assaying neutral and expressed genes, and iii) model-based coalescent approaches to phylogenetic reconstruction, population genetics, and studies of selection on pathogenicity genes. The broader impacts include generating critical baseline data on the genetic diversity of a pathogen that is a serious threat to global amphibian biodiversity. The results contribute to implementing a more dynamic approach to amphibian conservation that takes into account evolutionary processes in predictive management efforts and proactive conservation programs. This fellowship will also increase the participation of underrepresented groups at the postdoctoral level.

该行动资助 2009 财年 NSF 少数族裔博士后研究奖学金，并根据 2009 年美国复苏和再投资法案（公法 111-5）提供资助。该奖学金支持该研究员在主办实验室的一项研究和培训计划，该研究员还提出了一项扩大代表性不足的少数群体对生物学的参与的计划。大卫·罗德里格斯的这项研究和培训计划的标题是“Batrachochytrium dendrobatidis 的种群遗传学和新世界两栖动物的衰落”。这项研究的主办机构是康奈尔大学，赞助科学家是 Kelly Zamudio 博士。两栖动物正在以前所未有的速度减少，导致地球生物多样性减少，对这些物种发挥关键作用的生态系统造成潜在的可怕后果。壶菌 Batrachochytrium dendrobatidis (Bd) 与最近全球两栖动物数量下降有关。该项目正在调查中美洲和南美洲 Bd 的群体遗传学，以测试可能解释该流行病的两个相互竞争的假设；即与气候相关的流行病假说和传播病原体假说。培训目标是进一步发展以下方面的专业知识：i）生物信息学，ii）用于分析中性和表达基因的实验实验室技术，以及iii）基于模型的系统发育重建的合并方法、群体遗传学和致病基因选择研究。更广泛的影响包括生成对全球两栖动物生物多样性构成严重威胁的病原体遗传多样性的关键基线数据。研究结果有助于实施更加动态的两栖动物保护方法，该方法考虑了预测管理工作和主动保护计划中的进化过程。该奖学金还将增加博士后级别代表性不足群体的参与。
