The Amazon fauna is being threatened by several human activities. Mechanized
agriculture and overhunting are two of the main threats in the Tropics. About 20% of the
Amazon has been already deforested. However, the Amazon villages depend strongly on
agricultural production and subsistence hunting, as their source of food. Here, we assess
how 16 terrestrial mammal species responded to the effects of land-use change, induced
by subsistence agriculture and to subsistence hunting in a Sustainable Development
Reserve, Central Amazonia. For that, we monitored daily hunting activity for 13 years,
intensely surveyed terrestrial mammals within 160 km ² with camera-traps and mapped
the agriculture activity in a traditional village to investigate the effects of these two
anthropogenic pressures. Our main results showed that most game species are negatively
related to the intensity of hunting, though three intensely hunted species are not
responding to hunting at all. Although in apparent lower spatial stability than hunting,
subsistence agriculture seems to be less important to determine the presence of mammal
species, being positively related to the presence of two species, and negatively related to
only one species. Our results highlight the importance of understanding the effectiveness
of sustainable activities by traditional communities in the Brazilian Amazon and indicates
the accomplishment of integrated management plans to maintain the use of forest
resources in the long term by traditional communities. |
