Item Dinâmica da ocupação de Dendropsophus decipiens (Lutz, 1925) em bromélias de um fragmento de Mata Atlântica semidecidual(2019-12-13) Santos, Rebeca Vitória Inácio dos; Araújo, Alan Pedro de; Moura, Geraldo Jorge Barbosa de; http://lattes.cnpq.br/1348666346504103; http://lattes.cnpq.br/7843892415680764; http://lattes.cnpq.br/7183058148320345By offer microhabitat, bromeliads are of great importance in the life of amphibians. Anuran bromeliads eventually use bromeliads, and in the rainy season they go to water bodies like temporary puddles and lakes to breed. It is not known if these adults return to the same bromelials or even if their descendants also return. Thus the following work aims to understand the dynamics of occupation of Dendropsophus decipiens (Lutz, 1925) living in bromeliads during a dry and rainy period in bromelials located in the Alto da Buchada Forest in the Tapacurá ecological reserve in the metropolitan region of Recife. The collections were performed from October 2017 to October 2018, with a sampling effort of four people where the method used was the visual active search, done at night between 18:00 and 22:00. The collected specimens were weighed, measured individually marked by the elastomer technique. The abundance of anurans was 127 individuals collected and through this study found that precipitation and temperature were important factors in the presence or absence of these animals in the bromelials.Item Papel dos sinais químicos na seleção de recurso em Nasutitermes corniger (Blattodea: Isoptera)(2019-07-11) Silva, Aline do Nascimento Filgueira; Cristaldo, Paulo Fellipe; http://lattes.cnpq.br/0426390460269258; http://lattes.cnpq.br/1916876032100921Environments are formed by patches of resources with different suitability to the organisms. During foraging, organisms need to assess the costs and benefits involved in using a resource in order to make an appropriate choice for the exploration and use of that resource. An energy-efficient way of locating the resource to be explored is to use cues left by other organisms in the environment (i.e., social information). In the present study, we evaluated the role of intra- and interspecific chemical cues in the selection of food resource in Nasutitermes corniger (Termitidae: Nasutitermitinae). For this, we test the hypothesis that individuals of N. corniger are able to perceive and to avoid resources already used by different colonies of the same species and from different species. Initially, linear trail bioassays were conducted in order to verify the perception of intra- and interspecific chemical cues by N. corniger workers. Then, resource selection bioassays with a chance of choice were performed in order to evaluate the individuals' choice for food resources with intra- and interspecific chemical cues. In general, our results showed that chemical cues seem to modulate the food resource selection in N. corniger. The comprehension of the mechanisms involved in the resource selection plays a important role in the distribution of organisms in the environments, as well as the coexistence of termite species at local scale.
