To investigate the practice of hunting by local people in the southern Bahia region of Brazil and provide information to support the implementation of the National Action Plan for Conservation of the Central Atlantic Forest Mammals, we conducted 351 interviews with residents of three protected areas and a buffer zone. Thirty-seven percent of respondents stated that they had captured an animal opportunistically, 16% hunted actively and 47% did ...

Abstract The current extinction and climate change crises pressure us to predict population dynamics with ever-greater accuracy. Although predictions rest on the well-advanced theory of age-structured populations, two key issues remain poorly explored. Specifically, how the age-dependency in demographic rates and the year-to-year interactions between survival and fecundity affect stochastic population growth rates. We use inference, simulations ...

From 2006 through 2014, we conducted seroepidemiological surveys on non-human primates and sloths to investigate the possible circulation of arboviruses in Bahia Atlantic Forest, Brazil. We collected a total of 196 samples from 103 Leontopithecus chrysomelas, 7 Sapajus xanthosternos, 22 Bradypus torquatus and 7 Bradypus variegatus. Serum samples were tested using neutralization test and hemagglutination inhibition test to detect total antibodies ...

Protected areas have become a vital conservation strategy to protect wildlife; however, illegal activities performed by local people within and around protected areas may undermine their conservation goals. We used information from 169 direct interviews with rural residents in order to understand the factors affecting illegal behaviors related to hunting and deforestation in three protected areas and a buffer zone of the Southern Bahian Atlantic ...

Endangered species lists identify real and potential taxa extinction risks at global and regional scales, supporting decision-making processes and public policy. The construction of the first list of threatened species in Bahia state
started in 2013. This paper describes the evaluation of conservation status of mammals in Bahia and its main results. The list was built in three phases: (1) preparatory, (2) evaluation and (3) final ...

In a landscape fragmented by agriculture, the extent to which forest-dwelling primates can use the matrix between fragments can be critical for their long-term survival. So far, the golden-headed lion tamarin (Leontopithecus chrysomelas), an endangered primate inhabiting the Atlantic Forest of south Bahia, is only known to use shaded cacao (Theobroma cacao) agroforests within the matrix. We report on the use of a rubber plantation by a group of ...
