Stressors to native species under global change: Invasive species as vectors of infectious diseaseAs climate change progresses, invasive species will play an increasingly prominent role in mediating the spread of infectious diseases around the world. This research will investigate the role of invasive bullfrogs in spreading chytridiomycosis via the fungal pathogen Batrachochytrium dendrobatidis (Bd) to native amphibian populations. Invasive bullfrog populations now occur in numerous countries, and they compete with or prey on native frog species. In addition, bullfrogs are resistant to Bd and act as vectors in spreading Bd to native populations. This research will combine observational field studies with controlled laboratory experiments to disentangle the effects of invasive bullfrogs and Bd infection on native frogs, providing a framework for evaluating the potential for invasive species to serve as disease vectors. Moreover, the approach taken here is broadly applicable to other combinations of stressors, species pairs, and regions of the world, and will be particularly relevant as climate change broadly affects native-invasive and host-pathogen interactions in systems around the world.Approaches to broadening participation in ecological research will include an educational outreach program for high-school students and a training workshop for their teachers. These programs will give students and teachers the opportunity to form their own hypotheses, design a study to test those hypotheses, collect field data, analyze results, and present their studies to peers. The course for high school students will provide a valuable opportunity for students to conduct their own ecological research in the unique Sierra Nevada ecosystem, and the teacher workshop will build the content knowledge necessary to incorporate ecological research into high school learning objectives.

全球变化对本地物种的压力：作为传染病媒介的入侵物种随着气候变化的发展，入侵物种在介导全球传染病传播方面将发挥越来越重要的作用。 本研究将调查入侵牛蛙在传播壶菌病通过真菌病原菌Batrachochytrium dendrobatium（Bd）到本地两栖动物种群的作用。 入侵的牛蛙种群现在出现在许多国家，它们与当地的青蛙物种竞争或捕食。 此外，牛蛙对Bd有抗性，并作为传播媒介将Bd传播给本地种群。 这项研究将结合联合收割机观察实地研究与对照实验室实验，解开入侵牛蛙和Bd感染对本地青蛙的影响，为评估入侵物种作为疾病媒介的潜力提供一个框架。 此外，这里采取的方法是广泛适用于其他组合的压力，物种对，和世界各地的地区，并将特别相关的气候变化广泛影响本土入侵和主机病原体的相互作用在世界各地的系统。方法，以扩大参与生态研究将包括一个教育推广计划，为高中学生和他们的教师培训讲习班。 这些计划将使学生和教师有机会形成自己的假设，设计一项研究来测试这些假设，收集现场数据，分析结果，并向同行展示他们的研究。 高中生的课程将为学生提供一个宝贵的机会，在独特的内华达州山脉生态系统中进行自己的生态研究，教师工作坊将建立必要的内容知识，将生态研究纳入高中学习目标。
