0241169YatesThis Americas Program thesis enhancement project will support thesis dissertation research by Mr. Gerardo Suzan under the supervision of Dr. Terry L. Yates of the University of New Mexico. The research, in collaboration with the Dr. Armiens Blas of the Instituto Conmemorativo GORGAS in Panama, aims to study the way that changes in natural environments resulting from human activity affect the distribution of the reservoir for Hantavirus Pulmonary Syndrome and the risk of outbreaks in humans.In its simplest form, the dilution effect hypothesis suggests that high biodiversity reduces the frequency of some rodent-borne diseases. If so, several emerging zoonotic diseases may be related to the loss of biodiversity. Small mammal species richness and distribution in six Panamanian national parks with varying degrees of anthropogenic disturbance and size will be used to test this hypothesis. Preliminary surveys indicate that the lowest species richness was found in human dominated habitats where the hantavirus reservoir in Panama was exclusively collected and point to the conclusion that anthropogenic disturbance favors the hantavirus reservoir distribution, and possibly explains recent outbreaks.This study will establish a database for species distribution among different biomes, identify potential areas of highest disease risk based on the degree of habitat fragmentation, and, ultimately, increase our understanding of rodent reservoir ecology as it relates to anthropogenic activities. The basic conclusions of this project may apply to other vector-borne diseases in different regions of the world. If biodiversity and disease risks are strongly correlated, conservation of natural resources becomes even more important.

0241169Yates 这个美洲计划论文增强项目将支持 Gerardo Suzan 先生在新墨西哥大学 Terry L. Yates 博士的监督下进行的论文研究。 这项研究是与巴拿马戈尔加斯纪念研究所的 Armiens Blas 博士合作进行的，旨在研究人类活动引起的自然环境变化如何影响汉坦病毒肺综合征病毒库的分布以及人类爆发的风险最简单的稀释效应假说表明，高生物多样性可以降低某些啮齿动物传播疾病的发生频率。如果是这样，一些新出现的人畜共患疾病可能与生物多样性的丧失有关。巴拿马六个国家公园内小型哺乳动物物种的丰富度和分布，以及不同程度的人为干扰和规模，将被用来检验这一假设。初步调查表明，在人类主导的栖息地中发现了最低的物种丰富度，其中巴拿马汉坦病毒储存库是唯一收集的，并指出人为干扰有利于汉坦病毒储存库分布的结论，并可能解释最近的爆发。本研究将建立一个数据库不同生物群落之间的物种分布，根据栖息地破碎程度确定疾病风险最高的潜在区域，并最终增加我们对啮齿动物储存库生态学的了解，因为它与人类活动有关。该项目的基本结论可能适用于世界不同地区的其他媒介传播疾病。如果生物多样性和疾病风险密切相关，那么自然资源的保护就变得更加重要。
