Manejo genético para a conservação ex situ do Mutum-do-Sudeste, Crax blumenbachii (aves, cracidae)
(Universidade Federal de São Carlos, 2015-01-30)
Captive populations of endangered species are often small, isolated, and founded by a limited number of individuals, which makes them more susceptible to genetic drift and inbreeding effects. Thus, the preservation of the ...

A influência da estrutura de paisagens agrícolas nos índices de diversidade de aves
(Universidade Federal de São Carlos, 2015-10-01)
Habitat loss and fragmentation are currently the main causes of the global extinctions, caused mostly by replacing of the native vegetation by different land-uses. The graph theory supports the understanding of the landscapes, ...
