ABSTRACTPeople have hunted mammals in tropical Asian forests for at least 40,000
yr. This period has seen one confirmed global extinction (the giant
pangolin,Manis palaeojavanica) and range restrictions for several large mammals,
but there is no strong evidence for unsustainable hunting pressure until the
last 2000–3000 yr, when elephants, rhinoceroses, and several other species were

ABSTRACTProcesses of forest regeneration in two unlogged areas and in three
areas that were logged nearly 25 years ago were quantified in Kibale National
Park, Uganda. For forests to recover from logging, one would predict recruitment
and growth processes to be accelerated in logged areas relative to unlogged
areas, facilitating increased recruitment of trees into the adult size classes.

ABSTRACTWe examined the interaction between a palm and two bruchid beetles along
with several mammal species to explore how poachers and habitat fragmentation
may indirectly alter the spatial pattern of seed dispersal, seed predation, and
seedling recruitment in central Panama. The large, stony endocarps of Attalea
butyraceae decay slowly and bear distinctive scars when opened by rodents or
beetle... hiện toàn bộ
