The Effects of Parasites on a Free-ranging Howler Monkey Population in Panama

寄生虫对吼猴影响的初步调查 将对巴拿马巴罗科罗拉多岛的猴子进行。 的 寄生虫对自然种群的影响和生物代价 对非人类灵长类动物的研究知之甚少， 习惯性的岛屿人口是一个很好的选择， 初步研究。 两种特定的寄生虫将被调查， 跨学科团队。 的病理和感染率 吼猴蝇幼虫将被记录在案， 巴西疟原虫（Plasmodium brazilianum） 此外，还将尝试确定 环境压力（气候，营养等）对 虫害率。

A pilot investigation of the effects of parasites on howler monkeys on Barro Colorado Island, Panama will be conducted. The effects and biological costs of parasites on natural populations of nonhuman primates are poorly known and this well-known, habituated island population is a good choice for an initial study. Two specific parasites will be investigated by this inter-disciplinary team. The pathology and infestation rates for the howler monkey bot fly larvae will be documented as will those for the howler malarial parasite (Plasmodium brazilianum). Additionally, there will be an attempt to determine the effects of environmental stress (climatic, nutritional etc) on infestation rates.
