摘要

我们记录了印度西北部贾拉纳保护林(Jhalana Reserve Forest,JRF)中的豹(Panthera pardus fusca)种群的异父同母行为和社会群体行为。我们的观察结果表明,亚成体后代协助其母亲抚养新生幼崽,表现出以前从未记录过的异父异母行为。我们认为,家族内的特异性互动和特异性间的竞争共同影响了金钱豹种群的社会结构。具体来说,我们认为种间竞争和捕食,尤其是与条纹鬣狗(Hyaena hyaena)的竞争和捕食,可能会鼓励豹的异父异母行为。此外,我们还假设,异父异母关系与产后相亲相结合,是金钱豹提高其后代生存机会的另一种策略。

Alloparenting and family behaviours in leopards (Panthera pardus fusca)

We documented alloparenting and social group behavior within a leopard (Panthera pardus fusca) population in the Jhalana Reserve Forest (JRF), northwest India. Our observations revealed subadult offspring assisting their mothers in raising their newborn litters, exhibiting previously undocumented alloparenting behaviors. We propose that the familial intra-specific interactions and inter-specific competition collectively influence the social structure of the leopard population. Specifically we suggest that the inter-specific competition and predation, particularly with striped hyenas (Hyaena hyaena), may encourage alloparenting in leopards. Aditionally, we hypothesize that alloparenting, combined with natal philopatry, serves as an alternative strategy for leopards to enhance the survival chances of their progeny.

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
