Vliv fragmentace a ztráty habitatu na primáty

Anthropogenic activities and human encroachment may cause profound and often irrevocable changes in an environment. This may result in challenges for most of the wildlife, including our closest extant relatives, non-human primates. Worldwide, primates may be particularly susceptible to human-induced habitat alterations owing to their large body size, social way of life, slow reproduction, large home-ranges, naturally low population densities and often strong dependence on forest cover. Three main phenomena have been described as major threats for primates: loss of the natural habitat and its conversion to human-dominated landscape, fragmentation of the remaining patches of suitable habitat, and commercial bushmeat hunting. Here I review the first two processes. If primates survive the initial disturbance, they are forced to adjust their demographic, behavioural and dietary traits. However, this may not be enough for their persistence in a long term as their genetic diversity might be compromised. Moreover, also parasitic infections may impact severely the disrupted populations. In this thesis, I reviewed the current knowledge in primates demography, population genetics, dietary changes and parasite interactions in altered habitats. Most of the studies examined the African continent and Latin America, a...
