Maximum plant-community endemism at intermediate intensities of anthropogenic disturbance in Bolivian Montane forests

Article Abstract:

An unanticipated pattern of increased plant endemism at intermediate levels of anthropogenic disturbance observed during a study of the geographical distribution of botanical diversity and endemism in the Bolivian Andes is reported. Results reveal that conservation of endemic plant species in tropical forests can be achieved in forest areas subject to sustainable forest use without completely excluding human activities.

Genetic structure of a Mimosoid tree deprived of its seed disperser, the spider monkey

Article Abstract:

Research indicates that the tropical tree species Mimosoideae are reliant on the seed dispersal roles of frugivores to maintain plant genetic diversity, abundance, and fitness ability. In regions where seed dispersers such as the spider monkey have been eradicated due to subsistence hunting, Mimosoid saplings were found to be self-incompatible, and a fewer number of saplings were found under parent trees.

Plant-mammal interactions in tropical Bolivian forests with different hunting pressures

Article Abstract:

Studies done on plant-animal interactions and vegetation structure in two geographically close tropical Bolivian forests subjected to different hunting intensities are presenrbolited. Results suggest that subsistence hunting by sparsely distributed indigenous groups produces a complex landscape mosaic of different degrees of defaunation with distinct degrees of structural change.
