The objective of this study is to model the effects of urbanization and resultant habitat fragmentation on disease dynamics in large carnivore species--ecologically pivotal organisms that are sensitive to human disturbances. Bobcats, puma, and domestic cats will be evaluated simultaneously in three divergent ecosystems: high mountain desert (Colorado), everglades (Florida), and Mediterranean scrub habitat (California). The research will: (1) assess the relationship between habitat fragmentation and prevalence of viral, bacterial, and parasitic pathogens across a gradient of urbanization, (2) use transmission dynamics of selected disease agents as markers of connectivity of fragmented populations, and (3) evaluate the effect of urbanization on the incidence of cross-species disease transmission. The combination of a uniquely qualified research team with an extensive dataset on large carnivores presents an unprecedented opportunity to investigate the disease dynamics in these rare and difficult to study species. Training of graduate students in ecology, infectious disease, and epidemiology will be emphasized, as will training for pre- and post-doctoral veterinarians. Results will be made widely available to other scientists, conservation practitioners, and the general public. This research has a tremendous capacity to broadly impact areas of public and post-graduate education, career development for new investigators and persons from under-represented groups, and to enhance understanding of complex infectious disease ecological problems using extensive multi-disciplinary collaborations.

这项研究的目的是对城市化和由此产生的栖息地破碎化对大型食肉动物物种的疾病动态的影响进行建模 - 在事态上对人类障碍敏感的生物体。山猫，美洲狮和家猫将在三个不同的生态系统中同时进行评估：高山沙漠（科罗拉多州），大沼泽地（佛罗里达州）和地中海灌木丛栖息地（加利福尼亚）。研究将：（1）评估栖息地分裂与城市化梯度跨病毒，细菌和寄生病原体的流行率之间的关系，（2）使用选定疾病的传播动态作为碎片人群连通性的标志，（3）评估城市化疾病疾病疾病疾病进气的影响。 一个独特的研究团队与大型食肉动物上广泛的数据集的结合提供了一个前所未有的机会，可以调查这些罕见且难以研究的物种中的疾病动态。将强调对生态学，传染病和流行病学研究生的培训，以及对博士后和博士后兽医的培训。 结果将广泛地向其他科学家，保护从业者和公众提供。这项研究具有巨大的能力，可以广泛影响公众和研究生教育的领域，来自代表性不足的群体的新研究人员的职业发展，并通过使用广泛的多学科合作来增强对复杂的感染性疾病生态问题的理解。
