In Brazil, 124 species of ectoparasites of bats are known from the families Streblidae, Nycteribiidae, and Spinturnicidae. This study aimed to characterize the ectoparasites associated with bats in a restinga habitat in Sergipe, northeastern Brazil. Sampling occurred between October 2016 and September 2017 in the Reserva Particular do Patrimônio Natural do Caju through the capture of bats, using 10 mist nets. The ectoparasites collected were stored in 70% alcohol and subsequently identified. For the hosts, the parasitological indexes were calculated and, for the most abundant ones, the influences of the sex of the host and of seasonality on these indexes were evaluated. We collected 430 parasites, of which 77.90% belonged to the Streblidae family. The influence of host sex was observed only in terms of the prevalence between Periglischrus iheringi and Artibeus lituratus, with the highest values observed for females. This may be associated with the highest susceptibility of females to parasitism by the greater permanency in the shelter. In terms of the influence of seasonality, only the interaction between Carollia perspicillata and Trichobius joblingi was affected by temperature, with an increase in prevalence rates and mean intensity during the season with lower temperatures. This relationship may be associated with biological differences among parasites species. The present study identified six new species of ectoparasites and the occurrence of ticks on bats for Sergipe, in addition to registering 11 new bat-ectoparasite associations for the state and two for Brazil, contributing to an increase in our knowledge about bat-ectoparasite interactions.

Anthropogenic habitat fragmentation directly affects ecological processes, leading to negative biodiversity impacts for insects and other biota. Increased edge effects are one consequence of fragmentation, and may alter the composition or abundance of species in the remaining habitat fragments. Understanding the ways in which edge effects impact upon the biota is essential for conservation decision-making in fragmented landscapes. Therefore, the aim of this study was to analyze the seasonal patterns of abundance, richness, and composition of Drosophilidae in a Restinga forest fragment in the extreme south of Brazil, as a function of the distance from the edge to the interior of the fragment. The data were analyzed using SIMPER analyses, which showed that the edge and the forest interior were most dissimilar during winter, followed by spring, autumn and summer. An NMDS and the SIMPER analyses showed that the lower dissimilarity between the edge and interior in spring, autumn and summer, compared to winter, is driven by immigration of individuals from outside of the forest fragment. Furthermore, some species were asymmetrically distributed in the fragment, with some species restricted to the edge of the fragment and others to the interior. This information aids in the understanding of the functioning and dynamics of fragmentation, which is fundamental for the maintenance and integrity of environments and their fauna.
