The genus Zachaenus Cope is the least specious within Cycloramphidae, including two species: Z. carvalhoi Izecksohn, and Z. parvulus (Girard). Both are leaf litter species distributed across Atlantic forest remnants in Southeastern Brazil. Zachaenus carvalhoi occurs westerly in the states of Espírito Santo and Minas Gerais, and Z. parvulus easterly in the states of São Paulo, Rio de Janeiro, and Espírito Santo (Verdade et al. 2009; Motta et al. 2010; Salles & Maciel 2010; Oliveira et al. 2012; Guedes et al. 2019; Frost 2019). Both species build terrestrial nests, and larval development is endotrophic nidicolous (reproductive mode 21 after Haddad & Prado 2005; Lutz 1944; Thibaudeau & Altig 1999; Zocca et al. 2014). In this work, we describe the tadpoles of Z. carvalhoi, and discuss morphological aspects regarding other endotrophic tadpoles.

Artibeus Lituratus

Abstract The great fruit-eating bat (Artibeus lituratus) is a large-sized bat in the New World family Phyllostomidae. It is widely distributed and sometimes very abundant in different Brazilian biomes, in natural and anthropic environments. Studies in the tropics have found evidence of a decrease in A. lituratus captures during the winter, a dry and cold season with low fruit availability, especially in higher latitudes. However, the causes for the decrease in captures are poorly understood. The objective of this study was to test the influence of temperature and fruit availability on capture rates of A. lituratus in a fragmented Atlantic Forest landscape. Results indicate that temperature is the main variable that explains the changes in the number of captures of A. lituratus throughout the year, and that fruit availability plays only an adjacent role. In addition, we highlight possible negative consequences of climate change on the survival of this species.

Chrysocyon Brachyurus

The Atlantic Forest is one of the most biodiverse biomes in the world and has been severely degraded and fragmented, with the extirpation of most medium-sized and large vertebrates from the forest remnants. Here we present the results of a survey of medium-sized and large mammals in an area of protected seasonal semideciduous forest, the Floresta da Cicuta Area of Relevant Ecological Interest (ARIE-FC), Rio de Janeiro, Brazil, part the Atlantic Forest biome. We used camera traps (2,257 camera days) and direct observations over a 23-month period. We recorded 19 species (including two domestic species), seven of which are classified as at-risk, such as Leopardus guttulus (Hensel, 1872), Sylvilagus tapetillus Thomas, 1913, Alouatta clamitans Cabrera, 1940, and Chrysocyon brachyurus (Illiger, 1815). A diverse terrestrial mammal assemblage in the ARIE-FC reinforces the importance of small forest fragments for the conservation of biodiversity in human-modified landscapes of the Brazilian Atlantic Forest.

We present the first estimates of density of the Solitary Tinamou (Tinamus solitarius (Vieillot, 1819)) in the Reserva Natural Vale (RNV), one of the two largest remnants of the Atlantic Rainforest in the state of Espírito Santo, Brazil. We also modeled the spatial distribution and habitat use of the species using occupancy and detectability modeling. We used a line-transect survey to estimate density and abundance and camera traps to estimate habitat use and activity pattern. We conducted the survey within a 13 month period (April 2013 to May 2014). Estimated density was 9 ± 2 individuals/km2 and estimated population size for the entire RNV was 2115 ± 470 individuals. Occupancy was best described by distance to forest edge, distance between trees, poaching intensity, and understory cover. Detectability was affected by distance between trees and poaching intensity. We conclude that in the RNV, the Near Threatened T. solitarius is a diurnal species preferring intact closed-canopy forest but tending to avoid areas near to forest edges or areas under comparatively high intensity of poaching. These results reinforce the importance of RNV as a resource source for T. solitarius reproduction at Brazilian Atlantic forest remnants.

Most studies of cetacean habitat use do not consider the influence of anthropogenic activities. We investigated the influence of environmental and anthropogenic variables on habitat use by humpback Megaptera novaeangliae and Bryde’s whales Balaenoptera brydei off the coast of the Brazilian city of Rio de Janeiro. Although there are 2 marine protected areas (MPAs) in this area, few data are available on cetacean habitat use or on the overlap of different cetacean species within these MPAs. Our aim was to evaluate the effectiveness of the MPAs and propose a buffer zone to better protect the biodiversity of the study area. We conducted systematic surveys and developed spatial eigenvector generalized linear models to characterize habitat use by the species in the study area. Habitat use by humpback whales was influenced only by depth, whereas for Bryde’s whales there was the additional influence of anthropogenic variables. For Bryde’s whales, which use the area for feeding, sea surface temperature and the distance to anchorages had a major influence on habitat use. We also showed that neither of the MPAs in the study area adequately protects the hotspots of either whale species. Most of the humpback whale grid cells with high sighting predictions were located within 2 km of the MPAs, while areas of high sighting prediction of Bryde’s whales were located up to 5 km from the MPAs, closer to beaches. Our findings provide important insights for the delimitation of protected areas and zoning of the MPAs.
