Abstract The purpose of this study was to assess the relative abundance and activity patterns of terrestrial carnivorous mammals living in San Pablo de Valdés Wildlife Reserve, which is located in Península Valdés (PV), Chubut province, Argentina. To this end, camera traps were placed in different plant communities of this reserve and they were used from January 2015 to December 2016. A total of 256 independent events, with a sampling effort of 1811 camera nights, were obtained. The following species were identified in order of relative abundance: Conepatus chinga, Lycalopex gymnocercus, Leopardus geoffroyi, Puma concolor, and Leopardus colocolo, and the activity patterns of the first three were estimated. Those of P. concolor and L. colocolo could not be estimated as insufficient independent events were obtained. Our results show a cathemeral activity pattern in C. chinga and L. geoffroyi and a more nocturnal pattern in L. gymnocercus. Our results highlight the need to expand the sampling area to obtain further details on the behavioral patterns and population parameters of the carnivores identified. Knowledge of ecological issues, such as relative abundance and activity patterns of carnivorous mammals, is imperative to formulate monitoring and conservation programs.

阿根廷巴塔哥尼亚巴尔德斯半岛陆生食肉哺乳动物的相对丰度和活动模式

摘要 本研究的目的是评估生活在位于阿根廷丘布特省巴尔德斯半岛 (PV) 的圣巴勃罗瓦尔德斯野生动物保护区的陆生食肉哺乳动物的相对丰度和活动模式。为此，2015 年 1 月至 2016 年 12 月，在该保护区的不同植物群落中放置了相机陷阱，共获得了 256 个独立事件，采样工作为 1811 个摄像夜。按相对丰度的顺序确定了以下物种：Conepatus chinga、Lycalopex gunocercus、Leopardus geoffroyi、Puma concolor 和 Leopardus colocolo，并估计了前三种的活动模式。由于获得的独立事件不足，无法估计 P. concolor 和 L. colocolo 的那些。我们的结果显示了 C. chinga 和 L. geoffroyi 中的导管活动模式，以及 L. Gyoffroyi 中更多的夜间活动模式。我们的结果强调需要扩大采样区域，以获得有关已识别食肉动物的行为模式和种群参数的更多详细信息。生态问题的知识，例如食肉哺乳动物的相对丰度和活动模式，对于制定监测和保护计划至关重要。
