Abstract

The activity time of species can be influenced by biotic factors, such as competition, and abiotic factors, such as temperature. Different activity time may be important to favor coexistence among phylogenetically close species and similar habits. Thus, the objective of this work is to evaluate the temporal partition between armadillo species (Dasypus novencimctus, Euphractus sexinctus and Cabassous tatouay) and the influence of temperature on the activity pattern of these species. For this, camera traps and data-loggers will be distributed in a systematized way in the Furnas do Bom Jesus State Park and around and will be active for 60 days at each sampling point. After this period, the cameras will be redirected to new points until the entire study area is sampled. The activity pattern of each armadillo species will be described by the kernel density function, while the overlap of activity between each pair of species will be calculated by an overlap coefficient, ranging from 0 to 1. The influence of temperature on the activity pattern will be evaluated through the angular-linear correlation test, by using the data of activity hours recorded in cameras trap and temperature recorded by data-loggers distributed in the study area. The results will allow to understand how temperature affects the activity pattern of each species, besides describing how the temporal partition between three species of little-known mammals occurs.
