Bird communities were studied in two types of fragmented habitat of Atlantic forest in the State of Paraná, southern Brazil; one consisted of forest fragments that were created as a result of human activities (forest remnants), the other consisted of a set of naturally occurring forest fragments (forest patches). Using quantitative data obtained by the point counts method in 3 forest patches and 3 forest remnants during one year, species richness and relative abundance were compared in those habitats, considering species groups according to their general feeding habits. Insectivores, omnivores, and frugivores presented similar general tendencies in both habitats (decrease of species number with decreasing size and increasing isolation of forest fragment). However, these tendencies were different, when considering the relative abundance data: the trunk insectivores presented the highest value in the smallest patch while the lowest relative abundance was in the smallest remnant. In the naturally fragmented landscape, time permitted that the loss of some species of trunk insectivores be compensated for the increase in abundance of other species. In contrast, the remnants essentially represented newly formed islands that are not yet at equilibrium and where future species losses would make them similar to the patches.

AbstractSpecies that live in degraded habitats often show signs of physiological stress. Glucocorticoid hormones (e.g., corticosterone and cortisol) are often assessed as a proxy of the extent of physiological stress an animal has experienced. Our goal was to quantify glucocorticoids in free-ranging small mammals in fragments of Interior Atlantic Forest. We extracted glucocorticoids from fur samples of 106 small mammals (rodent genera Akodon and Oligoryzomys, and marsupial genera Gracilinanus and Marmosa) from six forest fragments (2–1200 ha) in the Reserva Natural Tapytá, Caazapá Department, Paraguay. To our knowledge, this is the first publication of corticosterone and cortisol levels for three of the four sampled genera (Akodon, Oligoryzomys, and Marmosa) in this forest system. We discovered three notable results. First, as predicted, glucocorticoid levels were higher in individuals living withing small forest fragments. Second, animals captured live using restraint trapping methods (Sherman traps) had higher glucocorticoid levels than those animals captured using kill traps (Victor traps), suggesting that hair glucocorticoid measures can reflect acute stress levels in addition to long-term glucocorticoid incorporation. These acute levels are likely due to urinary steroids diffusing into the hair shaft. This finding raises a concern about the use of certain trapping techniques in association with fur hormone analysis. Finally, as expected, we also detected genus-specific differences in glucocorticoid levels, as well as cortisol/corticosterone ratios.

The Atlantic Forest is highly anthropized, this reduce the areas of native vegetation and impacts the biodiversity of the biome. The objective of this study is to analyze forest remnants with native vegetation characteristics using a free GIS. This analysis takes place using landscape metrics and was based on the supervised vectorization of land use in the municipality of California, PR. The area of the vectored polygons was obtained and a classified, and then the calculation was made with the nearest neighbor index, mean distance observed, Patton diversity index and the perimeter/area ratio of forest fragments. The results show that most of the fragments have an area smaller than 1 ha, the fragments with more significant area (<50 ha) represent more than 16% of the native vegetation area. The small fragments are important to maintain the connectivity, since the withdrawal of these increases the mean distance observed and nearest neighbor index. Most of the fragments are elongated and amorphous in accordance with the perimeter/area ratio and the Patton diversity index respectively, this may demonstrate the fragments may be subject to edge effects. Even with these characteristics, these fragments may be part of what is planned in public policy for preservation in the Atlantic Forest in the state of Paraná. Therefore, even small fragments with little core area are important for maintaining biodiversity, especially in a highly anthropogenic landscape

AbstractTropical forests are being deforested worldwide, and the remaining fragments are suffering from biomass and biodiversity erosion. Quantifying this erosion is challenging because ground data on tropical biodiversity and biomass are often sparse. Here, we use an unprecedented dataset of 1819 field surveys covering the entire Atlantic Forest biodiversity hotspot. We show that 83−85% of the surveys presented losses in forest biomass and tree species richness, functional traits, and conservation value. On average, forest fragments have 25−32% less biomass, 23−31% fewer species, and 33, 36, and 42% fewer individuals of late-successional, large-seeded, and endemic species, respectively. Biodiversity and biomass erosion are lower inside strictly protected conservation units, particularly in large ones. We estimate that biomass erosion across the Atlantic Forest remnants is equivalent to the loss of 55−70 thousand km2 of forests or US$2.3−2.6 billion in carbon credits. These figures have direct implications on mechanisms of climate change mitigation.

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.

Espirito Santo

Verbenaceae is represented in Brazil by 15 genera and ca. 290 species, with most of its richness in the Cerrado and Atlantic Forest domains. The state of Espírito Santo has an area of 46,184.1 km2, wholly embedded in the Atlantic Forest. Nonetheless, due to the intense environmental degradation in the state, only 10.5% of its original vegetation remains. The present study is part of the “Flora do estado do Espírito Santo” project and aims to provide a taxonomic treatment to Verbenaceae in the state, as well as to analyze its distribution patterns, together with preliminary conservation assessments for each species. It is based on morphological analysis of herbaria collections, field expeditions, and literature compilation. Distribution maps were made for each species, while the preliminary conservation assessments followed the criteria proposed by the IUCN. Verbenaceae is represented in the state of Espírito Santo by 31 species arranged in 11 genera: Aloysia (2 spp.), Bouchea (1 sp.). Casselia (1 sp.), Citharexylum (1 sp.), Glandularia (1 sp.), Lantana (10 spp.), Lippia (4 spp.), Petrea (1 sp.), Priva (2 spp.), Stachytarpheta (6 spp.) and Verbena (2 spp.). Eight species occurring in Espírito Santo are threatened with extinction. Three new records are verified, including species of the genus Lantana. The dense rainforest, which covers most of the state’s territory, presents the most significant number of species (20 spp.), followed by pioneer vegetations (12 spp.), seasonal semideciduous forests (11 spp.), inselbergs (8 spp.), and ecological refuges (2 spp.). The main richness centers for Verbenaceae in the state of Espírito Santo are the municipalities of Linhares, Santa Teresa, Vitória, Vila Velha, and Guarapari in this order. In contrast, the family is noticeably little represented in the northern region of the state, as well as near its borders, where the forest remnants are highly fragmented and scattered. The current results contribute to the taxonomic and biogeographic knowledge of Verbenaceae, to the creation of conservation strategies for threatened species in the State of sspírito Santo, and reinforce the need of fieldwork in several areas of the state.

The pholcid genus Carapoia is revised and interspecific relationships are analysed cladistically. Five new species from the Brazilian Atlantic forest are described (C. ubatuba, C. brescoviti, C. una, C. crasto, C. rheimsae), and new records are given for the four previously described species. Cladistic analysis reveals a biogeographic split between a northern clade (Amazon, Venezuela, Guyana) and a southern clade (Brazilian Atlantic forest). While each of the three northern species is widely distributed, the six Atlantic forest species seem to be restricted to much smaller areas of forest remnants along the Atlantic coast.

Historical Factors

Forest fragmentation favours the propagation of some arboreal primate species that can alter the floristic composition of a community. This process may be associated with the loss of seed dispersants. In this work we propose to identify if the presence of frugivorous primates of medium and large size (Sapajus flavius and Alouatta belzebul) can influence forest diversity and structure. Further, we ask if the size of the fragment affects the availability of resources for these primates. Three fragments were studied in the Atlantic Forest of the State of Paraíba, Brazil, located in the municipalities of Sapé, Mamanguape, Rio Tinto, and Mataraca. In each area 25 plots of 50 x 4 m were delimited, randomly distributed along trails and transects. All trees with chest-high circumferences (CAP) above 12 cm found within the plots were marked with ribbons, and numbered continuously. A total of 114 plant species were documented in the Pacatuba Forest, 79 in the Asplan Forest, and 97 in the “Guaribas” (Sema III) Biological Reserve (REBIO) Forest. According to the Chao and Jacknife estimators, the REBIO Guaribas Forest can present more species than recorded in the present investigation. Species Tapirira guianensis, Protium giganteum and Protium heptaphyllum are the most abundant in the Asplan, Pacatuba and Sema III Forests, respectively. In the REBIO Guaribas Forest, the Shannon diversity index was (H') = 3.75, the Alpha-Fisher index was = 26.57 and the Simpson index (1-D) was = 0.90. Pacatuba was the forest fragment with the highest index of diversity (H') = 375, Alpha-Fischer = 33.74 and Simpson (1-D) = 0.95. Pacatuba and REBIO Guaribas Forsts possess greater Beta diversity. The results suggest that local and historical factors possibly increase Beta diversity, contributing to the increase in resources used as food by primates. Therefore, the presence of primates of medium and large size in the Pacatuba Forest may affect the diversity of resources, contributing to the dispersion of large fruits and seeds. The presence of primates of medium and large size can thus contribute to the preservation of floristic diversity in forest fragments.
