Abstract

Abstract The Desmarest's hutia (hereafter hutia, Capromys pilorides) is a rodent endemic to the Republic of Cuba (hereafter Cuba) and its associated islands. There is little recent research focused on hutia population abundance and range use in southeastern Cuba. We evaluated the current status of the hutia population in southeastern Cuba through (1) estimation of population density via walking and driving surveys, and (2) hutia spatial ecology via Global Positioning System (GPS) collars. Driving surveys indicated lower mean hutia density (x̄ = 0.14 hutias/ ha) than walking transects (x̄ = 1.13 hutias/ha). Three of 13 GPS-collared hutias provided sufficient data for range analyses as 10 hutias severely damaged their GPS units. Ranges were relatively small (50% Core Area, x̄ = 0.50 ha; 95% Range, x̄ = 2.63 ha) and individuals tended to stay very close to tree cover, only emerging at night to forage. We recommend continued monitoring of hutia populations due to their influence on rare vegetative communities and importance as a significant food source for the Cuban boa (Chilabothrus angulifer).

古巴东南部Desmarest's Hutia的种群丰度和范围利用

摘要Desmarest's hutia（以下简称hutia，Capromys pilorides）是古巴共和国（以下简称古巴）及其相关岛屿特有的啮齿动物。最近很少有研究关注古巴东南部胡蒂亚种群的丰度和范围使用。我们通过（1）通过步行和驾驶调查估计人口密度，以及（2）通过全球定位系统（GPS）项圈估计胡蒂亚人口的空间生态，评估了古巴东南部胡蒂亚人的现状。驾驶调查显示，胡蒂亚平均密度（x̄=0.14胡蒂亚/公顷）低于步行样带（x̃=1.13胡蒂亚斯/公顷）。13只带GPS项圈的hutias中有3只为距离分析提供了足够的数据，因为10只hutias严重损坏了它们的GPS单元。范围相对较小（50%核心区，x̄=0.50公顷；95%范围，x̃=2.63公顷），个体倾向于非常靠近树木覆盖，只有在夜间才出现觅食。我们建议继续监测胡蒂亚种群，因为它们对稀有植物群落的影响以及作为古巴蟒蛇（Chilabotrus angulifer）重要食物来源的重要性。
