使用标记重捕获和无线电遥测技术在加拉帕戈斯群岛对两个野猫 Felis catus 种群的空间组织进行了检查。两个种群都位于相同的栖息地植被类型中，并且猫的密度大致相等。资源密度和习性异质性不同的两个地点在活动范围大小和重叠量方面也存在显着差异。雄性平均活动范围为 3.04 平方公里，雌性平均活动范围为 0.82 平方公里。每月的家庭范围没有显着变化。活动模式大致呈双峰，黎明和黄昏时达到高峰，中午时达到低点。站点之间的日常移动路径有所不同。资源水平和活动范围模式表明，在较贫穷的地区，基于资源抑制的资源阈值领土性，而在较富裕的地区没有发现领土性，这表明野猫的适应性和生态灵活性。
The spatial organization of two populations of feral house cats Felis catus, was examined in the Galapagos Islands using mark-recapture and radio telemetry. Both populations were located in the same habitat vegetation type and had approximately equal densities of cats. Two sites differing in resource density and habital heterogeneity also differed significantly in home range size and amount of overlap. Male home ranges averaged 3.04 km2 while those of females averaged 0.82 km2. Monthly home ranges did not vary significantly. Activity patterns were roughly bimodal with peaks near dawn and dusk and lows near midday. Daily movement paths differed between sites. Resource levels and home range patterns suggest a resource threshold territoriality based on resource depression at the poorer site while no territoriality was found at the richer site demonstrating the adaptability and ecological flexibility of feral cats.
