Abstract

Kinkajous are one of the most widely distributed Neotropical mammals, nonetheless, their nocturnal habits have posed challenges on the study of their ecology and behavior. Here, we used arboreal camera trapping in a pristine Amazonian forest in Ecuador, and ad libitum data from direct encounters in a lowland and a highland forest in Colombia to describe their activity patterns and describe anecdotal data on their diet and reproductive behaviors. As expected, kinkajous are strictly nocturnal and seem to be active throughout the entire night, although in our study there was less activity towards the beginning and the end of the night. Kinkajous were observed to be mostly solitary, rarely in groups of two to three adult individuals. Although their diet has not been described in detail, fruits from Moraceae and Urticaceae appear to be important components of their diet. Their reproductive behavior involves an isolated pair of kinkajous, and may be interrupted by other males. Pairs seem to meet for reproductive purposes and range together for several hours, during which courtship may take place, ending in copulation, which lasts for approximately 3 min. After copulation, the male and female appear to separate and return to their solitary habits. The results of this study complement the scarce information on the elusive kinkajous in the Neotropical forests.

关于金卡鼠(Potos flavus)生态、活动模式和行为的说明
锦鸡儿是新热带地区分布最广的哺乳动物之一,然而,它们的夜间活动习性给生态学和行为学研究带来了挑战。在这里,我们在厄瓜多尔的亚马逊原始森林中使用了树栖相机诱捕法,并在哥伦比亚的低地和高地森林中使用了直接接触的自由数据来描述它们的活动模式,并描述了有关它们的饮食和繁殖行为的轶事数据。不出所料,金卡伊蚋是严格的夜行性动物,似乎整夜都在活动,不过在我们的研究中,夜初和夜末的活动较少。据观察,金卡伊螈大多独来独往,很少有两到三只成年个体成群活动的情况。虽然没有详细描述它们的食物,但桑科和荨麻科的果实似乎是其食物的重要组成部分。它们的生殖行为由一对孤立的金卡祖斯参与,可能会被其他雄性打断。成对的金龟子似乎是为了繁殖而相遇,并在一起活动数小时,期间可能会求爱,最后交配,持续时间约为 3 分钟。交配后,雄性和雌性似乎会分开,恢复独居习性。这项研究的结果补充了有关新热带森林中难以捉摸的锦鸡儿的稀缺信息。

期刊介绍: Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
