Few Data

Muçunungas are vegetation formations in sandy soils, similar to restingas in structure and composition, ranging from grassy woody (GL) to low-density trees or muçununga forests (FM). Although some birds are known for this phytophysiognomy, few data are available on the structure of their communities, and on the ecological resources' use. This research aims to present the first commented list on the birdlife of muçunungas, and to describe how they share the ecological resources in different formations. Five areas of muçunungas having different vegetation structures were sampled in southern Bahia, Brazil, between 2011 and 2019. We recorded 216 species; 32 endemics to the Atlantic Forest and 14 threatened with extinction. The most abundant feeding guilds were insectivores (77 species), omnivores (53), and frugivores (32). A total of 109 species were recorded in FM and 183 in GL. Strictly forest birds prevailed in FM (66 %), and forest, semi-forest, and open-area species were detected in similar amounts in GL. Generalist birds have prevailed in muçunungas, sharing many species with the surrounding environments, as in restingas. Due to the paucity of specific public policies, and similarities of muçunungas and restingas, we suggest that similar conservationist strategies could be applied to birds in these two environments of the Atlantic Forest.

Parsimony Analysis Of Endemicity

Rivers as barriers to dispersal and past forest refugia are two of the hypotheses proposed to explain the patterns of biodiversity in the Atlantic Forest. It has recently been shown that possible past refugia correspond to bioclimatically different regions, so we tested whether patterns of shared distribution of bird taxa in the Atlantic Forest are 1) limited by the Doce and São Francisco rivers or 2) associated with the bioclimatically different southern and northeastern regions. We catalogued lists of forest birds from 45 locations, 36 in the Atlantic forest and nine in Amazon, and used parsimony analysis of endemicity to identify groups of shared taxa. We also compared differences between these groups by permutational multivariate analysis of variance and identified the species that best supported the resulting groups. The results showed that the distribution of forest birds is divided into two main regions in the Atlantic Forest, the first with more southern localities and the second with northeastern localities. This distributional pattern is not delimited by riverbanks, but it may be associated with bioclimatic units, surrogated by altitude, that maintain current environmental differences between two main regions on Atlantic Forest and may be related to phylogenetic histories of taxa supporting the two groups.

The orchid-bee faunas of ‘Parque Nacional do Monte Pascoal’, ‘Parque Nacional do Descobrimento’ and three other Atlantic Forest remnants ranging from 1 to 300 ha in southern Bahia, eastern Brazil, were surveyed. Baits with seventeen different scents were used to attract orchid-bee males. Four thousand seven hundred and sixty-four males belonging to 36 species were actively collected with insect nets during 300 hours from November, 2008 to November, 2009. Richness and diversity of orchid bees found in this study are the highest ever recorded in the Atlantic Forest domain. Eufriesea dentilabris (Mocsáry, 1897) and Eufriesea violacea (Blanchard, 1840) were collected at the ‘Parque Nacional do Monte Pascoal’, the first record of these species for the state of Bahia and the northernmost record for both species. Females Exaerete dentata (Linnaeus, 1758) were also collected at ‘Parque Nacional do Monte Pascoal’ and old records of Eufriesea aeneiventris (Mocsáry, 1896) in this area makes this site the richest and most diverse concerning its orchid-bee fauna in the entire Atlantic Forest and similar to areas in the Amazon Basin.

The aim of this study is to survey the angiosperms of two montane forest remnants in the southern Bahia, Brazil: Corcovado (SCO) and Pedra Lascada (SPL). Both fragments are located in the municipality of Almadina and Barro Preto, respectively, and are 18 km distant from each other. We sampled 899 species of angiosperms distributed in 437 genera and 116 families. The SCO was the richest area with 678 species, distributed in 367 genera and 100 families. SPL showed 466 species in 269 genera and 88 families. The percentage of species identified was 85.8% and of this total, 37.7% are endemic to the Atlantic Forest, 11.2% are endemic to southern Bahia and northern Espírito Santo and 7% are disjunct between the Atlantic Forest and Amazon. The remaining percentages (44.3%) were of species widely distributed. The richest families in the two areas were Orchidaceae (10%), Rubiaceae (7%), Bromeliaceae (5.5%), Melastomataceae (4.2%) and Poaceae (4%). The richest genera were Psychotria (2%),Piper (1.8%), Ocotea (1.6%),Vriesea (1.5%) and Peperomia (1.4%). More than half of the recorded species showed non-arboreal habit, regarding life forms documented. That comes against the assertion that many authors in the tropical forests, where species richness in angiosperms is expected for non-woody species, especially in montane forests. Twelve species have been identified as new, but seven others already described from collections previously obtained in these two areas. Orchidaceae, Rubiaceae, Poaceae and Bromeliaceae showed significant richness in this study these families are commonly reported as the richest in other inventories in the Atlantic Forest in southern Bahia reinforcing their importance to the regional flora. The high levels of richness, endemism, and the growing numbers of new taxonomic discoveries from the SPL and SCO sites indicate the biological importance of these two forest remnants. The implementation of parks or other protected environmental reserves would be essential to the conservation of its species.

Only three of the 12 recognized species of Trachycephalus Tschudi (Frost 2011) present an occipital crest— Trachycephalus atlas Bokermann, T. nigromaculatus Tschudi, and T. jordani (Stejneger and Test). The latter species is found in Colombia, Ecuador, and Peru. Trachycephalus nigromaculatus is found in the Brazilian Atlantic Forest of São Paulo, Rio de Janeiro, Espirito Santo, Minas Gerais, and southern Bahia states, while T. atlas is restricted primarily to the Caatinga of the Brazilian Northeast (Frost 2011), but overlaps with T. nigromaculatus in the Atlantic Forest of southern Bahia. The two species can be differentiated by the more pronounced posterior cephalic plate, wider inter-orbital distance, and lower and wider head in T. atlas (Bokermann 1966). Herein we describe the acoustic characteristics of advertisement call of T. atlas and compared with other Trachycephalus species.

Kielmeyera ferruginosa, a new species of Calophyllaceae from the Atlantic Forest of southern Bahia, is here described and illustrated. The species is critically endangered and can be easily distinguished from other Kielmeyera species by the rusty coloration of the trunk and branches, orange-colored latex, and the occurrence in flooded areas. It differs from the other species of the section Prolifera by the leaves with secondary veins relatively more distant from each other and prominent on the abaxial surface. Diagnostic characters and the state of conservation of the new species are discussed, and an identification key for K. ferruginosa and related species from series Rupestres and Neglectae is provided.

AbstractThe Brazilian Atlantic Forest is a severely threatened biodiversity hotspot and many remnants exist only as fragments. In order to understand how bat assemblage structure within a forest fragment surrounded by an urban matrix might respond to seasonality and different habitats, we sampled bats over 39 nights in the forest fragment of Gericinó-Mendanha Massif, Rio de Janeiro State. From February 2006 to January 2010, we captured 874 bats, belonging to 25 species and eight different feeding guilds. Frugivorous species were the most abundant, representing 83.33% of captures, and the gleaning insectivores were the least abundant (1.47%). We did not find changes in bat species composition between seasons, although capture rate was higher in the rainy season. However, we did find significant differences in species abundance between seasons. The habitat influence did not significantly differentiate the assemblages, but species richness was higher in the mature ombrophilous forest. The community composition indicates that this conservation unit is an important remaining fragment for maintaining the diversity and richness of bats, although it is possible that historical processes of environmental exploitation have already resulted in a loss of species.
