Density and population size of mammals in remnants of Brazilian Atlantic forest

Article Abstract:

Research indicates that forest reserve size in Brazil is significantly inadequate to support biodiversity and wildlife conservation goals. Studies based on three primate and two rodent species over 1 kg in body weight showed that forest reserve size should be equal to or greater than 20,000 ha; however, only 20% of protected areas in Brazil's Atlantic forest meet that size requirement.

Effects of human colonization on the abundance and diversity of mammals in eastern Brazilian Amazonia

Article Abstract:

Research indicates that forest clearing and prolonged hunting pressure are the primary factors driving the paucity of the Amazonia mammal population in Brazil. Human disturbance also affected species diversity, mean and total biomass, and abundance; numbers of nongame species were found to increase in correlation with the rate of forest disturbance.

Poachers alter mammal abundance, seed dispersal, and seed predation in a neotropical forest

Article Abstract:

Results show that mammal abundance is inversely related to poaching intensity. Seed-dispersal is carried out by nonvolant mammals with beetles and rodents acting as predators.
