Descripción
Basic information on the natural history of species is essential for studies of evolutionary biology and ecology, in addition to being fundamental for developing conservation strategies. This study aimed to provide information on the activity and substrate use of Bothrops atrox in a floodplain forest in the western Brazilian Amazon. With a sampling effort of 816 personhours of time constrained, nocturnal visual search, 28 observations of 27 individuals were made, of which 16 were adults and 11 were juveniles. The encounter rate of B. atrox was one snake every 30 person-hours of searching, and most individuals were recorded during the rainy season. Considering the snake assemblage, Bothrops atrox represented 20.8% of the sampledsnakes, out of a total of 130 individuals of 21 species, being the second most frequent species. The ecological and morphological differences between the congeneric species B. atrox and B. bilineatus in this floodplain forest, as well as resource availability, likely influence their local abundance. These factors would also help minimize the probability of interspecific competition between these syntopic species.
Informações básicas sobre a história natural das espécies são essenciais para estudos de biologia evolutiva e ecologia, além de serem fundamentais para desenvolver estratégias de conservação. Este estudo teve como objetivo fornecer informações sobre a atividade e uso do substrato da serpente Bothrops atrox em uma floresta de várzea no oeste da Amazônia brasileira. Com um esforço amostral de 816 horas-pessoa de procura visual limitada por tempo noturna, foram realizadas 28 observações de 27 indivíduos, dos quais 16 eram adultos e 11 juvenis. A taxa de encontro de B. atrox foi de uma serpente a cada 30 horas-pessoa de procura, e a maioria dos indivíduos amostrados foi registrada durante a estação chuvosa. Bothrops atrox representou 20.8% das serpentes amostradas, de um total de 130 espécimes de 21 espécies, sendo a segunda espécie mais frequente. As diferenças ecológicas e morfológicas entre as espécies congenéricas B. atrox e B. bilineatus nesta floresta de várzea, bem como a disponibilidade de recursos, provavelmente influenciam a abundância local das espécies. Esses fatores também podem ajudar a minimizar a probabilidade de competição interespecífica entre as duas espécies.
