The brown howler monkey Alouatta fusca once had a wide geographical distribution throughout a large part of the Atlantic forest in Brazil. Today only 5 per cent of these forests remain and the species is endangered. Howler monkeys can thrive in small forest fragments but they are more vulnerable to hunting, disease, and predation in these habitats than in undisturbed forests. Brown howler monkeys are important seed dispersers of several plant species, particularly in isolated forest fragments where specialized frugivores are absent. In protected areas without large predators howlers can reach high densities and the management of these populations is necessary to avoid inbreeding.

Abstract The vegetation cover in the Atlantic Forest has been converted to human use or degraded by human activities, which declined the vegetation to 16% of its original extent. Although several protected areas have been created in this Neotropical biome over the past decades, our knowledge of the amphibian species within these areas is still far from adequate. Here, we present lists of anuran species from three different areas of Parque Estadual da Serra do Mar: núcleos Curucutu, Santa Virgínia and São Sebastião. To survey anuran species, we visited six sampling units (two ponds, two streams and two trails inside forest fragments) in each locality. Samplings were accomplished from December 2014 to February 2015, December 2015 to February 2016 and December 2016 to February 2017, totalizing 27 days of field samplings in each sampling unit. We recorded 34 anuran species in the Núcleo Curucutu, 44 species in the Núcleo São Sebastião and 42 species in the Núcleo Santa Virgínia, totalizing 65 species belonging to 12 families (number of species in parentheses): Bufonidae (5), Brachycephalidae (6), Centrolenidae (1), Craugastoridae (1), Cycloramphidae (2), Hemiphractidae (1), Hylidae (29), Hylodidae (3), Leptodactylidae (12), Microhylidae (2), Odontophrynidae (2), and Phyllomedusidae (1). We hope that these lists can be useful for future studies as well as helping in the management and conservation planning of these protected areas.

Reduced to a tiny fraction of its original area, much of the Atlantic Forest habitat remaining in eastern Brazil is distributed in small, isolated patches on private land. The potential role of these fragments in the conservation of the region's primate fauna is poorly understood. As part of a study of buffy-headed marmosets Callithrix flavicepsin Minas Gerais, forest remnants were visited in order to evaluate this potential. Marmosets were observed in one-third of the sites and may exist in up to 60 per cent of forest patches in the region. A second threatened primate, the brown howler monkeyAlouatta fusca,may occur in one-quarter of the sites visited. The muriquiBrachyteles arachnoideswas not encountered. Overall, the survey suggests that, with appropriate management, privately owned forest fragments may play an increasingly important role in the conservation of the Atlantic Forest's fauna in this and other regions.

The new species Prepusa dibotrya from the Brazilian Atlantic Forest in Espírito Santo is described and illustrated, with comments on its ecology, geographical distribution, and conservation status. The new species is similar to P. viridiflora and must be considered “critically endangered” in accordance with the criteria of the IUCN Red List of endangered plant species.

Abstract: Pheidole is a genus with wide geographical distribution and diversity, especially in the leaf litter of neotropical forests, where nests are found at the soil-litter interface, in the soil and vegetation, among leaves, seeds, and twigs. Despite the availability of twigs and Pheidole species diversity in the leaf litter, most of this resource is not occupied, which suggests the existence of filters. This study analyzes whether twigs occupied by Pheidole species differ for the outer structure and anatomy of the wood. Twigs were collected from preserved Atlantic Forest fragments in southeastern Brazil. Twigs with Pheidole colonies were measured and the wood anatomy analyzed. We collected 224 twigs with Pheidole colonies, but the analysis was done at 41% due to wood decomposition. Five species were recorded in these twigs, which differ for the outer structure and anatomy of the wood. These results suggest the existence of preference in the occupation of twigs determined by wood structure.

Fragmentation threatens biodiversity and forest-dwelling animals can be especially vulnerable. Neotropical primates inhabit forests and play ecological roles in maintaining forest biodiversity. Currently, many primate communities are restricted to forest fragments. We (1) evaluated the influence of environmental, matrix, and site attributes on species richness and functional traits of primates in the Neotropics; and (2) evaluated the effect of the sub-region on the relationships between primates and environmental, matrix, and site attributes. We conducted literature searches to find published data on primate communities in forest fragments throughout the Neotropics. Each fragment was assigned to 1 of 11 sub-regions: Mesoamerica, Tumbes-Chocó-Magdalena, Caribbean, Orinoco, Amazon, Atlantic Forest, Cerrado, Chaco, Andes, Caatinga, and Pampa. Based on actual and expected species occurrences, we calculated the proportion of primate species retained in the fragments, the mass retained, and dietary items retained considering reproductive and vegetative plant parts and prey. We used linear mixed models to correlate primate variables with environmental, matrix, and site attributes. Fragment area was more important for primate retention than environmental, matrix, and site attributes, with primate retention being higher in larger fragments. Fragment size was positively correlated with all primate variables, except for retention of prey consumption, whose retention decreased as water bodies and density of buildings in the matrix increased. Fragments within protected areas retained larger species than unprotected fragments. The proportion of extant mass retained and vegetative plant parts in the diet were highest in Mesoamerica and lowest in the Atlantic Forest. Conservation planning of Neotropical primates should consider both the differences among sub-regions, forest restoration to increase fragment size, and the creation of new protected areas, even in fragmented landscapes.

Marmosets of the genus Callithrix are small-bodied platyrrhines, endemic to Brazil. In the last 30 years, there has been a constant interest in studying their biology, ecology and conservation. In this study, we compiled a systematic review to evaluate the trends and advances of marmoset research, from biodiversity and conservation perspectives. We searched for articles published in peer-reviewed journals within the main academic search engines, using the keywords “marmoset” OR “sagui” OR “Callithrix”. We found 68 published articles with a focus on biodiversity and conservation. The number of articles has increased over the years, most of them consisting of research from the Atlantic Forest biome. Callithrix penicillata (26 articles) and C. jacchus (21) were the most studied species. The number of studies was associated with the species’ geographical distribution. From a conservation perspective, the most threatened species showed the narrowest geographical distribution, a lower number of studies and, on average, a smaller protected area size. We concluded that trends and biases in biodiversity and conservation scientific literature of Callithrix are directly and indirectly associated with its geographical distribution. Species with wide geographical distribution are more studied, better known and protected. We highlight that the major effort of studies must be towards marmoset populations from the transition region of the Atlantic Forest-Cerrado and Caatinga biomes, and on threatened species within narrow geographical ranges.

A floristic inventory was made in the Reserva Particular do Patrimônio Natural Fazenda Tabatinga to show the importance of small forest fragments for conservation of the biodiversity of the Atlantic Forest. The reserve protects a vegetation mosaic typical of coastal habitats in an area of ca. 20 ha, located in the northern part of the Brazilian Atlantic Forest. Samples of vascular plants were collected between January 2010 and November 2011, and altogether 329 species were recorded. These are classified in 230 genera and 79 families of angiosperms and two genera and two families of ferns. Among the species found, 28 are endemic to the Atlantic Forest, while others are rare and restricted to the Pernambuco Endemism Center. In addition, three threatened species were detected. The presence of endemic, rare, and threatened species, along with floristic patterns typical of coastal areas of Brazil, reinforce the importance of the area for the conservation.

SummaryWe tested the hypothesis that endemic bird species of the Brazilian Atlantic forest are more sensitive to forest fragmentation than non-endemics in a fragmented landscape in northern Paraná state of southern Brazil. Levels of sensitivity (high, medium, and low) were previously determined in the landscape based on the occurrences of bird species in 14 forest fragments. We evaluated 112 forest bird species and found that endemic species were more sensitive than non-endemics. Among the endemic species, highly sensitive species tended to have smaller geographic ranges. In a second analysis, we determined that birds at the edges of their geographic ranges in northern Paraná were more vulnerable to forest fragmentation. Combining both factors we found that endemic birds at the edge of their ranges were the most sensitive to fragmentation. Our results suggest that endemics and species at the edges of larger ranges might need larger tracts to ensure their continued existence within that region. Our results, however, also indicate that even small forest fragments may have considerable value for non-endemics and for species closer to the centres of their ranges.
