1. Diet and microhabitat use by juveniles Rhinella ornata (Anura, Bufonidae) in an insular Brazilian Atlantic Rainforest area
Resumo A validação de muitas espécies de anuros é baseada em uma análise morfológica e descritiva de um pequeno número de espécimes com uma distribuição geográfica limitada. O gênero Scinax Wagler, 1830 é um grupo controverso com muitos táxons duvidosos e incertezas taxonômicas devido ao grande número de espécies crípticas. Um exemplo são

2. SOIL CHEMICAL CHANGES AND RESEMBLANCES IN A CHRONOSEQUENCE RAINFOREST-SUGARCANE-PASTURELAND IN THE ATLANTIC FOREST BIOME
ABSTRACT This study evaluated soil chemical and isotopic changes in soils of a chronosequence rainforest-sugarcane-pasture in the Atlantic Forest biome, Brazil. Soil samples were collected (0-20 cm) in areas of native Brazilian Atlantic rainforest, sugarcane plantation and pastures of Brachiaria decumbens. The soil analyses performed were: pH (water 1:2.5),

3. Sexual Systems of Plants in a Brazilian Montane Forest
ABSTRACT In this study, vegetation reproduction has been investigated in order to understand aspects of speciation, structuring and composition of plant communities. Thus, we sought to characterize the frequency of sexual systems from species recorded in seed rain occurring in a tropical rainforest (Atlantic Forest) in Caparaó National Park, Espírito Santo

4. Description of a new Brazilian species of Mycodrosophila (Diptera, Drosophilidae) with emphasis on the morphology of phallic sclerites
ABSTRACT Mycodrosophila is a cosmopolitan genus of Drosophilidae that comprises approximately 130 species with mycophagous habitats. In this study, we described a new species of Mycodrosophila based on morphological traits and included details of the male terminalia. The holotype is from Eugênio Lefévre, locality in Campos do Jordão municipality, SP, Braz

5. Simulation of pattern of gene flow in Canjerana fragments in the Brazilian Atlantic Rainforest for evaluating genetic conservation strategies
RESUMO: O fluxo gênico, cuja efetividade é função do modelo e da taxa, assume especial importância na conservação de recursos genéticos por permitir a conectividade de populações isoladas geograficamente, sujeitas à redução da variabilidade genética. O entendimento de como o fluxo gênico ocorre pode contribuir no planejamento de ações para

6. In vitro culture and acclimatization of Cattleya xanthina (Orchidaceae), an endangered orchid of the Brazilian Atlantic Rainforest
Resumo Cattleya xanthina é uma orquídea neotropical endêmica da Mata Atlântica brasileira, com alto risco de extinção. Neste trabalho analisamos diferentes meios de cultura sobre o desenvolvimento de C. xanthina, e seu status de nitrogênio endógeno. Meios de cultura estudados: Knudson C (KC), Vacin & Went (VW) e Murashige & Skoog (MS), e o meio MS co

8. Extra-pair paternity in a Neotropical rainforest songbird, the White-necked Thrush Turdus albicollis (Aves: Turdidae)
ABSTRACT Over the last two decades, several studies have shown that the mating systems of various birds are more complex than previously believed, and paternity tests performed with molecular techniques have proved, for instance, that the commonly observed social monogamy often presents important variations, such as extra-pair paternity. However, data are st

9. Vascular epiphytes on Pseudobombax (Malvaceae) in rocky outcrops (inselbergs) in Brazilian Atlantic Rainforest: basis for conservation of a threatened ecosystem
Resumo Este estudo avaliou a riqueza de epífitas vasculares sobre Pseudobombax sp. nov. em três inselbergs do Domínio Atlântico no estado do Espírito Santo e avaliou a similaridade florística entre as áreas. Foram amostrados 111 forófitos, em três regiões no sul do estado do Espírito Santo e identificados 151 espécies, 77 gêneros e 21 famílias

10. Genetic analysis reveals candidate species in the Scinax catharinae clade (Amphibia: Anura) from Central Brazil
Abstract Scinax (Anura: Hylidae) is a species-rich genus of amphibians (113 spp.), divided into five species groups by morphological features. Cladistic analyses however revealed only two monophyletic clades in these groups: Scinax catharinae and Scinax ruber. Most species from the S. catharinae clade are found in Atlantic rainforest, except for Scinax canas

Spondias (Anacardiaceae)This paper describes the correlation between the phenolic composition and the molecular phylogenetic reconstruction of five
Spondias species (Anacardiaceae). Two of these species (S. venulosa andSpondias sp.) occur in rainforest areas and the other three are widely distributed in Brazil (S. dulci Quím. Nova. Publicado em: 2015-07

12. Diversity of bryophytes in priority areas for conservation in the Atlantic forest of northeast Brazil
The northeastern Brazilian Atlantic forest is the region with the greatest diversity of bryophytes in the country. However, knowledge about bryophytes is irregularly distributed among Brazilian regions. Therefore, we aimed to contribute to knowledge about bryophytes on a regional scale in the northeastern Atlantic forest, to identify the centers of bryophyte
