Padrão de atividades e do uso da área de vida de Callithrix jacchus em ambiente urbano: como os fatores ecológicos e antrópicos influenciam na dinâmica?

Abstract

The home range of an animal can be defined as a location used by an individual or social group of animals to carry out their daily activities, such as reproduction, feeding and social interactions. Considering that environmental and seasonal factors can change the dynamics of the pattern of activities and the use of the home range, the present study aimed to monitor two groups of Callithrix jacchus and identify how they use their home ranges and the patterns of activities performed by them, groups according to seasonality. The groups called Q and Z were observed between August 2014 and June 2015 in the Dois Irmaos State Park (PEDI) Recife-PE. The animals were captured and tagged. Data collection used the instantaneous scan method, applied in ten-minute sessions. The categories that presented the highest frequencies in the Q and Z groups were: displacement, stationary and feeding. Analyzing the monthly data set, it was noticed that the activities of the Q group were carried out most of the time in theforest environment in the months of September 2014 and from November 2014 to June 2015, while in all months of analysis, group Z performed most activities in the zoo area and not in the forest. The diet of the Q group was composed mainly of fruits, while the diet of the Z group included mostly provided foods. Thus, the diet of the Q group was influenced by a seasonal factor such as the fruiting of vegetables throughout the dry season and the diet of the Z group was directly or indirectly influenced by human presence at the study site.
