Abstract

Abstract The small Indian mongoose (Urva auropunctata) is an opportunistic omnivore introduced to sugar producing islands primarily to control rat (Rattus spp.) populations, yet is now considered an invasive pest species on multiple Caribbean islands. Data on home range estimates of mongooses in Puerto Rico and other regions are limited. We fitted 24 mongooses (15 males and nine females) with very high frequency (VHF) radio collars at the Cabo Rojo National Wildlife Refuge in southwestern Puerto Rico and tracked them via radio telemetry for up to six months. The raw mean (SE) minimum convex polygon home range among 24 mongooses was 45.03 (8.30) hectares. The mean (SE) fixed kernel 95% estimate was 38.37 (5.78) hectares, and the 50% core area estimate was 7.89 (1.29) hectares. Our home range estimates are similar to previous estimates in the Caribbean and other islands, but larger than those reported from their native range in India. Our study adds new information to the small body of literature available on mongoose home ranges and is one of the few studies conducted in a lowland dry semi-deciduous forest in southwestern Puerto Rico. Additional research on mongoose home ranges in suburban/rural habitats, as well as in agricultural areas, would provide valuable information for the management of wildlife disease and damage conflicts associated with mongooses in the Caribbean region.

波多黎各西南部小型印度猫鼬(Urva auropunctata)的家庭活动范围估计

小型印度猫鼬(Urva auropunctata)是一种机会性杂食性动物，引入产糖岛屿主要是为了控制大鼠(Rattus spp.)种群，但现在被认为是加勒比海多个岛屿的入侵害虫。关于波多黎各和其他地区猫鼬家庭活动范围的估计数据是有限的。在波多黎各西南部的卡波罗霍国家野生动物保护区，我们给24只猫鼬(15只公猫和9只母猫)戴上了甚高频(VHF)无线电项圈，并通过无线电遥测技术跟踪了它们长达六个月的时间。24只猫的原始平均最小凸多边形家园范围为45.03(8.30)公顷。平均(SE)固定内核95%估计值为38.37(5.78)公顷，50%核心区估计值为7.89(1.29)公顷。我们对它们在加勒比和其他岛屿的栖息地的估计与以前的估计相似，但比在印度的原生栖息地报告的要大。我们的研究为关于猫鼬栖息地的少量文献提供了新的信息，并且是在波多黎各西南部低地干燥半落叶森林中进行的少数研究之一。对猫鼬在郊区/农村栖息地以及农业地区的栖息地范围进行进一步研究，将为管理加勒比区域与猫鼬有关的野生动物疾病和损害冲突提供宝贵的信息。
