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.

在波多黎各西南部的小型印度猫鼬(Urva auropunctata)的房屋范围估计

小型印度猫鼬(Urva auropunctata)是一种机会性杂食动物,被引入食糖生产岛,主要是为了控制老鼠(Rattus spp。)种群,但现在被认为是多个加勒比岛屿上的入侵害虫。关于波多黎各和其他地区猫鼬的家庭范围估计数据有限。我们在波多黎各西南部的卡波罗霍国家野生动物保护区为24只猫鼬(雄性15例,雌性15例)安装了甚高频(VHF)无线电项圈,并通过无线电遥测对其进行了长达六个月的追踪。24个猫鼬中的最小平均凸面多边形原始范围为45.03(8.30)公顷。固定核平均含量95%的估计平均值(SE)为38.37(5.78)公顷,而核心面积50%的估计平均值为7.89(1.29)公顷。我们的房屋范围估计值与之前在加勒比海和其他岛屿的估计值相似,但比其在印度本土范围内的估计值更大。我们的研究为猫鼬家庭范围内的文献提供了新的信息,这是在波多黎各西南部的低地干旱半落叶林中进行的少数研究之一。关于郊区/农村生境以及农业地区猫鼬家庭范围的其他研究,将为管理野生生物疾病和与加勒比地区猫鼬有关的破坏冲突提供有价值的信息。我们的研究为猫鼬家庭范围内的文献提供了新的信息,这是在波多黎各西南部的低地干旱半落叶林中进行的少数研究之一。关于郊区/农村生境以及农业地区猫鼬家庭范围的其他研究,将为管理野生生物疾病和与加勒比地区猫鼬有关的破坏冲突提供有价值的信息。我们的研究为猫鼬家庭范围内的一小部分文献增添了新的信息,并且是在波多黎各西南部的低地干燥半落叶林中进行的少数研究之一。关于郊区/农村生境以及农业地区猫鼬家庭范围的其他研究,将为管理野生生物疾病和与加勒比地区猫鼬有关的破坏冲突提供有价值的信息。
