Abstract

The domestic dog (Canis lupus familiaris) is known to have evolved from gray wolves, about 15,000 years ago. They frequently exist as free-ranging populations across the world. They are typically scavengers and well adapted to living among humans. Most canids living in and around urban habitats tend to avoid humans and show crepuscular activity peaks. In this study, we carried out a detailed population-level survey on free-ranging dogs in West Bengal, India, to understand the activity patterns of free-ranging dogs in relation to human activity. Using 5669 sightings of dogs, over a period of 1 year, covering the 24 h of the day, we carried out an analysis of the time activity budget of free-ranging dogs to conclude that they are generalists in their habit. They remain active when humans are active. Their activity levels are affected significantly by age class and time of the day. In addition, we provide a detailed ethogram of free-ranging dogs. This, to our knowledge, is the first study of this kind, which might be used to further study the eco-ethology of these dogs.

适应城市的自由放养犬的时间活动预算
家犬(Canis lupus familiaris)是在大约1.5万年前由灰狼进化而来的。它们经常以自由放养的方式生活在世界各地。它们是典型的食腐动物,非常适应与人类生活在一起。大多数生活在城市及其周围的犬科动物倾向于避开人类,并表现出黄昏活动高峰。在这项研究中,我们对印度西孟加拉邦的自由放养犬进行了详细的种群水平调查,以了解自由放养犬的活动模式与人类活动的关系。在一年的时间里,我们对5669只狗进行了一天24小时的观察,对自由放养的狗的时间活动预算进行了分析,得出结论:它们在习惯上是多面手。当人类活动时,它们也会保持活跃。他们的活动水平受到年龄、班级和一天中的时间的显著影响。此外,我们还提供了自由放养犬的详细族谱。据我们所知,这是第一次这样的研究,可以用来进一步研究这些狗的生态行为学。

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)
