Consequences of Simulated Loss of Open Cerrado Areas to Bird Functional Diversity
(ASSOC BRASILEIRA CIENCIA ECOLOGICA E CONSERVACAO, 2010)
Over the past 35 years, more than two thirds of the Cerrado`s original expanse has been taken by agriculture. Even if some attempts have been made to conserve closed cerrado physiognomies, open cerrado physiognomies, richer ...
Frustration Behaviors in Domestic Dogs
(Routledge, 2013-01)
During extinction a previously learned behavior stops being reinforced. Besides the decrease in the rate of the instrumental response, it produces an aversive emotional state known as frustration. This state, at the ...
Prior exposure to stress delays extinction but does not modify reinstatement of nicotine-induced conditioned place preference
(Pontifícia Universidade Católica do Rio de Janeiro (PUC-Rio)Universidade de Brasília (UnB)Universidade de São Paulo (USP), 2010-06-01)
Studies in humans suggest that exposure to stress is related to relapse to tobacco use. The reinstatement of conditioned place preference (CPP) provides a simple, noninvasive and easy approach to investigate the mechanisms ...
Species Turnover through Time: Colonization and Extinction Dynamics across Metacommunities
(Univ Chicago Press, 2016-06-01)
Island biogeography and metacommunity theory often use equilibrium assumptions to predict local diversity, yet nonequilibrium dynamics are common in nature. In nonequilibrium communities, local diversity fluctuates through ...
Social wasp-flower visiting guild interactions in less structurally complex habitats are more susceptible to local extinction
(Univ Estadual Feira Santana, 2013-09-01)
Several studies have shown that habitat complexity is an important factor for the dynamic and stability of interacting species. However, it is not known how the habitat complexity may affect the tolerance of wasp-flower ...

Megafauna extinction, tree species range reduction, and carbon storage in Amazonian forests
(2016-02-01)
During the Late Pleistocene and early Holocene 59 species of South American megafauna went extinct. Their extinction potentially triggered population declines of large-seeded tree species dispersed by the large-bodied ...
