Estimates about groups size, density and composition of primates are commons in the papers, because they are a solid base for futures studies in landscape ecology and ethology, for example. They are also essential to know ...

The ecosystem functions can be considered goods and services when they serve to generate and maintain the human activities and well being. However, the economic markets generally neglect the participation of those services ...

Anurans are ectothermics and have permeable skin; therefore, they respond to changes in humidity and temperature conditions of the microhabitat. Thus, these environmental factors, as well as prey availability, must influence ...

Forest fragmentation and habitat loss are considered the major threats to biodiversity. Studies of the effects of these processes on the species should also include landscape analysis rather than just local analysis as in ...

Ectotherms must regulate body tempetarute inside a tolerable range of temperature to optmize physiological functions. In this context, behavioural thermoregulation is an important strategy for metabolic compensation. Shifts ...

Few environmental factors exert so much influence on the physiology of animals as temperature. Each activity carried out by an animal occurs in a range of body temperatures that is physiologically appropriate. Some reptiles ...

The mountains of the Brazilian Atlantic Forest have a high degree of endemism and its biogeographical history is poorly explored. One hypothesis for the diversification of montane organisms, related to the refuge theory, ...

Most studies about the effects of anthropogenic landscape changes on biodiversity have focused on parameters such as species richness and abundance. Few are those that aim to understand the effects of these disturbances ...

Animals may use external or internal cues to navigate towards an original location. Here we studied the homing ability of the harvestman Heteromitobates discolor (Arachnida, Opiliones). We tested the importance of (1) their ...

Several arthropod species use chemicals to detect sexual partners. In harvestmen (Arachnida, Opiliones) there are evidences that chemicals have an important role in intra-specific communication. Using the behavior of ...
