RESUMO
The study of the influence of human hunting pressure on the social behavior of vertebrates requires a large background on both the hunting pressure and the social behavior of the species. Literature about this subject is relatively scarce. Most of the papers are restricted to shifts in demography, and are generally "species-specific". However, human hunting pressure cant not only affect demography but also some factors of the social behavior of a species such as parental care, territoriality, reproductive behavior, group-size, fraying behavior, mating system, and intraspecific competition. The presence of hunters in the area can lead the animals to move out of their original home-rangers. This can breakup the social structure and can cause long-term effects on the demography of hunted as well as nearby populations, amplifying the impact of hunting. On the other hand, harvest can be compensated in territorial species by "surplus population" of non-territorial individuals. Moreover, alternatively, an increase in the reproductive activity, as a response to hunting pressure, can compensate its effects in some species. Understanding the implications of hunting pressure in the social behavior of vertebrates might be decisive to the establishment of wildlife management and conservation programs. Manipulative experiments might help us to model such complex interactions. The occurrence of qualitative and quantitative changes in vertebrate social behavior directly or indirectly related to human hunting pressure is reviewed and analyzed in this paper.
