25. Floristic composition and spatial distribution of vascular epiphytes in the restingas of Maracanã, Brazil
Vascular epiphytes constitute a life form that is important to maintaining the biological diversity of forest ecosystems, because they provide food resources and specialized microenvironments for fauna in the forest canopy. This study aimed to describe the floristic composition and ecological aspects of vascular epiphytes occurring in the restingas (coastal

26. Hippeastrum species in areas of restinga in the state of Rio de Janeiro, Brazil: pollen characters
The order Asparagales comprises 14 families, five of which occur in Brazil. Amaryllidaceae is a family of economic relevance and includes numerous ornamental genera. The genus Hippeastrum is widely distributed in Brazil and comprises 34 species, 11 of which occur in areas of restinga (coastal woodland) and Atlantic Forest in the state of Rio de Janeiro. The

27. Structure and phytogeographic relationships of swamp forests of Southeast Brazil
Swamp forests are associated with soils that are saturated or inundated because of a high water table. In Brazil, little is known about the plant ecology of such forests. In this paper, we aimed to describe the phytosociological structure of the tree layer of swamp forests in Restinga de Jurubatiba National Park, in the northern part of the state of Rio de J

28. Pollen grains in quaternary sediments from the Campos Basin, state of Rio de Janeiro, Brazil: Core BU-91-GL-05
Here, we describe pollen grains extracted from a Pleistocene-Holocene sediment core (BU-91-GL-05; 22°48'45"S; 41°54'13"W) taken from the Albacora Slope (22°48'45"S; 41°54'13"W), located in the Campos Basin of the northern region of the state of Rio de Janeiro, Brazil. The analysis resulted in the identification and morphological description of 46 types o

29. Diversidade e abundância de fixadores de nitrogênio de vida livre e micro-organismos amônio-oxidantes em solos de Mata Atlântica do Estado de São Paulo / Diversity and abundance of the free-living nitrogen-fixing bacteria and ammonia-oxidizing microorganisms in Atlantic Forest soils of the São Paulo State
A estrutura das comunidades de arquéias e bactérias amônio oxidantes (AOA e AOB, respectivamente) e de bactéria fixadoras de nitrogênio de vida livre (BFNVL) foi avaliada em amostras de solo coletadas em três áreas de Mata Atlântica do Estado de São Paulo (Santa Virgínia, Picinguaba e Restinga) por meio de metodologias independentes de cultivo.

30. Diversidade de Bacteria e Archaea em solos de Mata Atlântica no estado de São Paulo / Bacterial and archaeal diversity in soil from Atlantic forest of São Paulo State
A Mata Atlântica é um bioma constituído de vários ecossistemas e considerado um hotspot da biodiversidade mundial. Sua extensão vai do Rio Grande do Sul até o Piauí, compondo cerca de 15% do território nacional. Porém, aproximadamente 93% da formação original da Mata atlântica já foi devastada. Seus solos são comumente pobres (baixa disponibili

31. Feeding ecology of the pygmy gecko Coleodactylus natalensis (Squamata: Sphaerodactylidae) in the Brazilian Atlantic Forest
We studied the feeding ecology of a population of Coleodactylus natalensis Freire, 1999, an endemic gecko of Atlantic Forest fragments in the state of Rio Grande do Norte, northeastern Brazil. Lizards (N = 49) were collected manually through active search in the four habitats of Parque Estadual Dunas de Natal, type locality of the species. In the laboratory,

32. Ciclagem de carbono e nitrogênio no solo sob restinga do Estado de São Paulo / Carbon and nitrogen cycling in soil under Restinga of São Paulo State
The Atlantic Forest is the second largest Brazilian forest, now having only 7.6% of its original size. The remaining spots are found in Serra do Mar and Serra da Mantiqueira, in southeastern Brazil, the restinga biome is the most susceptible to degradation. The main objective of this work was to study the cycle of carbon and nitrogen in sandy soils under dif

33. Spatial distribution of bryophytes across the Atlantic Forest, southeastern Brazil / Distribuição espacial de briófitas na Floresta Atlântica, Sudeste do Brasil
A fim de compreendermos a influência da altitude sobre as comunidades briófitas, realizamos o estudo da brioflora de seis cinturões altitudinais (10 m, 50 m, 400 m, 800 m, 950 m e 1170 m) no Parque Estadual da Serra do Mar, litoral norte do estado de São Paulo. Nossos objetivos foram descrever e analisar os padrões de distribuição espacial das espéci

34. Modeling distribution of Phoneutria bahiensis (Araneae: Ctenidae): an endemic and threatened spider from Brazil
Phoneutria bahiensis Simó & Brescovit, 2001 is a large ctenid spider inhabiting the states of Bahia and Espírito Santo, Brazil. Considering that it is probably endemic, this species was included in the Brazilian red book of threatened species. Here, we predict the distribution range of P. bahiensis using 19 bioclimatic variables in the model design. The mo

35. New records, threatens and conservation status for Dichotomius schiffleri Vaz-de-Mello, Louzada & Gavino (Coleoptera: Scarabaeidae): an endangered dung beetle species from Brazilian atlantic forest ecosystems
Dichotomius schiffleri Vaz-de-Mello et al is often cited as endemic to the preserved coastal sandy-dune vegetation (restinga) of Guriri Island, Espírito Santo state, and is included in the Brazilian List of Endangered Fauna as "critically endangered" (CR). However, we recorded its occurrence in twelve additional sites along the coasts of Espírito Santo, Ba
