Researchers at the University of California, Los Angeles, San Francisco State University, the Jet Propulsion Laboratory/NASA, the University of California, Davis, and the Institute of Ecology at Vilnius University, Lithuania, will conduct a study of the effects of deforestation on the spread of infectious diseases in African rainforest birds. During the past 13 years, researchers have collected more than 4,000 individual blood samples from over 200 rainforest bird species in a variety of habitats across Cameroon, the Ivory Coast, and Uganda. Significantly, the samples were collected from sites both before and after habitat degradation, permitting a unique examination of the direct effects of human-induced habitat alterations. Using complementary techniques of blood smear analysis and molecular biology, samples will be assayed for the pathogens that cause malaria, trypanosomiasis, filiariasis, and tuberculosis. These diseases in birds have very similar pathologies to their human counterparts, making the study of birds an excellent model system. We will use satellite imagery data to predict how changes in forest composition may affect the spread of diseases in the future. The effects of deforestation on health are diverse and are becoming increasingly apparent with the highly publicized recent outbreaks of several diseases spread to humans by animals. This research project is significant because it will develop models to predict how deforestation will influence future disease outbreaks and facilitate development of reforestation strategies. In addition, the research will involve the training of students and researchers at U.S. institutions serving minorities, and abroad, in Lithuania and Africa.

加利福尼亚大学，洛杉矶分校，旧金山州立大学，喷气推进实验室/NASA，加利福尼亚大学，戴维斯大学和立陶宛维尔尼乌斯大学生态学研究所将研究辩护森林侵害对非洲雨林鸟类传染病的影响。在过去的13年中，研究人员在喀麦隆，象牙海岸和乌干达的各种栖息地中收集了来自200多种雨林鸟类物种的4,000多个单独的血液样本。值得注意的是，这些样品是从栖息地退化前后的地点收集的，允许对人类诱导的栖息地改变的直接影响进行独特的检查。使用血液涂片分析和分子生物学的互补技术，将分析引起疟疾，锥虫病，毛细血管病和结核病的病原体。这些鸟类中的疾病与人类对应物具有非常相似的病理，使对鸟类的研究成为了极好的模型系统。我们将使用卫星图像数据来预测未来森林组成的变化如何影响疾病的传播。 森林砍伐对健康的影响是多种多样的，并且随着最近几种疾病迅速爆发的几种疾病传播给人类，越来越明显。该研究项目很重要，因为它将开发模型来预测森林砍伐将如何影响未来的疾病暴发并促进造林策略的发展。 此外，该研究将涉及在美国和国外，立陶宛和非洲的美国机构的学生和研究人员的培训。
