ABSTRACTHabitat fragmentation and conversion are among the human activities that
pose the greatest threat to species persistence and conservation of
biodiversity. This is particularly true in the Neotropics, where bats represent
important components of biodiversity from taxonomic and functional perspectives,
and provide critical ecosystem services (e.g., seed dispersal and pollination).

Forest Regeneration in Logged and Unlogged Forests of Kibale National Park, UgandaBiotropica - Tập 29 Số 4 - Trang 396-412 - 1997
Colin A. Chapman, Lauren J. Chapman
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.

Big Fish are the Best: Seed Dispersal of Bactris glaucescens by the Pacu Fish (Piaractus mesopotamicus) in the Pantanal, BrazilBiotropica - Tập 40 Số 3 - Trang 386-389 - 2008

ABSTRACTWe studied the potential role as seed disperser of the pacu fish
(Piaractus mesopotamicus, Characidae) in the Pantanal of Brazil. The most
important food item in the diet of the pacu in the wet season was fruits of the
palm Bactris glaucescens found in the guts of 73 percent of all fishes collected
(N= 70). We found a positive relationship between fish length, weight, and gape
size and the... hiện toàn bộ
The Impact of Hunting on the Mammalian Fauna of Tropical Asian ForestsBiotropica - Tập 39 Số 3 - Trang 292-303 - 2007
Richard T. Corlett
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
progressively... hiện toàn bộ
