Myotis albescens has a wide distribution, occurring from southern Mexico to central Argentina and Uruguay, where it is usually caught near streams or flooded areas. M. albescens roosts during the day in cavities such as hollow logs, rock cavities, and buildings. Here, we describe a group of M. albescens roosting in a highway underpass in an Atlantic Forest area in Rancharia, southeastern Brazil. The group was found inside a culvert with a shallow stream passing through it. The animals left the roost and were mist-netted in the first hours of the night. The M. albescens group was composed of 18 individuals, eleven males and seven females. In October, all males had descended testes and two females were pregnant, as confirmed by abdominal palpation. Morphological characters of the specimens fell in the known variation for the species. Our data show that highway underpasses can be important day roosts for bats, especially if riparian areas are preserved

Tropidodryas serra is an endemic snake from the Brazilian Atlantic Forest and despite its wide distribution, little is known about its ecology. Tropidodryas serra is an oviparous snake, but there are few available data on its  reproductive cycle. In this paper, we present the first report of oviposition of T. serra in captivity with successfully hatching. A pregnant female was captured in the area of Non-Governmental Organization (NGO) Dacnis Project, Ubatuba-SP, southeastern Brazil, and held captive. The spawning of 7 eggs and the development of offspring were observed. The eggs (measuring 4x1.35 cm in average) hatched in 90 days, with 6 healthy neonates and 1 stillborn. Based on a unique successful hatching of T. serra eggs in captivity, the present study confirmed with naturalistic data reproductive characteristics of the species, such as egg laying in December and low number of atresic eggs, corroborating that the species should present few reproductive events and concentrated throughout the rainy season.

This study aimed to characterize the trophic structure of the fish assemblage in streams of the Serra Japi, an ecotonal area between the Atlantic Forest and inland forests of São Paulo State, Southeastern Brazil. Fish were collected with electrofishing equipment in 15 sites covering different regions, substrate types and riparian vegetation, distributed throughout the Caguaçú River, Caxambú, Piraí and Guapeva River micro-basins, during the rainy (January/February) and dry season (June) of 2007. The 589 specimens analyzed from 22 species, were assigned to different trophic groups, discriminated through a matrix of similarity, based on the food index (IAi). The results show the formation of seven groups with a predominance of insectivorous and omnivorous species, followed by detritivores, piscivores, omnivore-carnivores and herbivores, which consumed mostly items of autochthonous origin, where algae and young insects were dominant. Canonical correspondence analysis (CCA), correlating the biomass of trophic groups to environmental variables, showed that omnivores, insectivores and omnivore-carnivores displayed a wide distribution, while detritivores, herbivores and piscivores were restricted to specific locations, related to different physical and chemical variables as total nitrogen, conductivity and temperature. Despite the increase in total biomass at the most urbanized sites, the results indicate that the streams maintain a diverse community, suggesting that most of them are in preserved conditions.

Abstract Coccidia are protozoan parasites that are frequently observed in fecal samples from wild birds, and they are extremely important for biodiversity, host specificity and conservation. The aim of the present study was to identify and quantify the coccidian species from wild birds caught in a fragmented area of Atlantic Forest in the municipality of Guapimirim in the state of Rio de Janeiro, which is located around the Serra dos Órgãos National Park. A total of 101 birds were caught and identified. The highest prevalence and density were observed in the family Columbidae (Columbiformes). Among the families of Passeriformes, the highest prevalences and densities were of birds in the families Thraupidae and Turdidae. The majority of the positive samples and those with higher densities were collected in the afternoons. Eleven coccidian species of Isospora and Eimeria were identified. Seven of these species that were morphologically identified are undescribed in the scientific literature and are believed to be new species. The present study highlights the wide distribution and dispersion of coccidia of wild birds in southeastern Brazil, and records the municipality of Guapimirim, in the state of Rio de Janeiro, as a new locality for parasitism, along with the new hosts recorded.

Highways limit the movement and dispersion of wild animals and contribute to their loss due to roadkills, leading to the isolation and decline of populations, increasing the risk of local extinction. The Lowland Tapir Tapirus terrestris is the largest neotropical herbivore-frugivore, and despite its wide distribution in South America it is threatened with extinction. In this study we report six roadkill events of tapirs between 2014 and 2019 in a section of a federal highway crossing the mosaic of Atlantic Forest reserves called Sooretama, one of the last tapir refuges in southeastern Brazil. The traffic in this area is heavy with inadequate speed control, while exotic fruit trees growing along the highway attract wild animals. Water drainage tunnels serve as passageways for some species, including tapirs. However, the tunnels located under the highway are not continuously maintained, reducing its effectiveness. The loss of at least one tapir per year can have serious long-term consequences for one of the last viable lowland tapir populations in the entire Atlantic Forest. Emergency measures are required to avoid vehicle-tapir collisions.

Nearly a century ago, wing venation was introduced in gracillariid taxonomy as a means to diagnose closely related genera and species groups. Recent advances in non-destructive virtual micro-dissections suggest promising approaches with which to revisit the relevance of wing venation characters on historic primary type specimens. Many unique type specimens in Gracillariidae and other microlepidoptera groups preserved in museum collections are in poor condition, and over the course of history have suffered loss or damage to their abdomens. Consequently, genitalia morphology is not available for diagnoses and comparisons. In this paper we emphasize the need to include the type species and type specimens into the broader context of taxonomic studies on micro-moths in general and the family Gracillariidae in particular. The genus Caloptilia has a world-wide distribution and has been the subject of research for more than 200 years, yet the generic boundaries and groupings within the genus are still unresolved due to the lack of a reliable set of taxonomic characters obtained from the primary types. We describe a method of virtual descaling of the fore- and hindwings using the unset micro-moth type specimen of Caloptilia stigmatella Fabricius, 1781, in order to demonstrate that the study of historic and fragile type specimens and diagnoses of their internal morphological characters becomes possible by applying new and non-destructive technology.
