1. EFFECTS OF SEASONAL AIR TEMPERATURES AND LIGHT ON LEAF TRAITS AT ATLANTIC MONTANE FOREST, BRAZILIAN SOUTHEAST
ABSTRACT Seasonal variation of temperature could place physiological constraints on the distribution and performance of tropical forest plants, associated with light and water availability. A simple way to assess the relationship between temperature and plant physiology is through the characterization of leaf traits. The main aim of this study was to evaluat

2. 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

3. Lycopodiaceae in Brazil. Conspectus of the family III. The genera Huperzia and Phlegmariurus
Resumo A subfamilia Huperzioideae de Lycopodiaceae apresenta 41 espécies no Brasil. O gênero Huperzia é representado por uma única species e Phlegmariurus por 40. Estas ocorrem na maioria dos habitats com climas úmidos, desde florestas tropicais de planície a florestas montanas e vegetação de campos de altitude. Há 25 endêmicas, mais da metade do t

4. Local environmental controls of Atlantic Forest tree community assembly on a coastal continental island in southeastern Brazil
ABSTRACT Tropical forests with high species diversity are commonly found in rugged montane areas. We investigated causes of local tropical forest tree community assembly on a continental island with heterogeneous terrain. We recorded tree community (absolute species abundance), topography, soil, litter and location in 40 sampling units on two opposite sides

5. Arbuscular mycorrhizal fungal communities in soils under three phytophysiognomies of the Brazilian Atlantic Forest
ABSTRACT Arbuscular mycorrhizal fungi (AMF) play an important role in plant community productivity and structure, and so studying the factors that affect the diversity and structure of this fungal community is important for understanding their ecology in tropical forests. We investigated AMF spore communities and root colonization under three forest phytophy

6. Can regional and local filters explain epiphytic bryophyte distributions in the Atlantic Forest of southeastern Brazil?
ABSTRACT Environmental conditions in distinct tropical rainforest phytophysiognomies can act as regional filters in determining the distribution of montane bryoflora likewise, local filters inherent to phorophyte species can have modulating influences. We analyzed the bryophyte communities in three phytophysiognomies of Atlantic Forest, in order to examine t

7. Diversity and distribution of the bryophyte flora in montane forests in the Chapada Diamantina region of Brazil
Bryophytes constitute an important component of tropical rain forests, which provide microhabitats favorable for their establishment. Bryophytes are also quite responsive to changes in microclimate, which makes them good bioindicators. This study aimed to determine the diversity and distribution of bryophytes in upper and lower montane forests of the Chapada

8. IMPLICAÇÕES DO MUTUALISMO TROFOBIÓTICO COM HEMÍPTEROS NA ATIVIDADE DE FORRAGEIO DE FORMIGAS ARBORÍCOLAS EM UM ECOSSISTEMA ARBÓREO MONTANO / IMPLICAÇÕES DO MUTUALISMO TROFOBIÓTICO COM HEMÍPTEROS NA ATIVIDADE DE FORRAGEIO DE FORMIGAS ARBORÍCOLAS EM UM ECOSSISTEMA ARBÓREO MONTANO
This study investigates a new case of trophobiotic interaction that occurs between ants and the herbivore Calloconophora pugionata, specialist of Myrcia obovata. In the first chapter we describe the trophobioses and analyze the benefits of the tending ants for treehopper survival and fecundity. Using an exclusion experiment we show that the absence of tendin

9. Influence of variations micro-environmental in the community of palm montane tropical rain forest, Núcleo Santa Virginia, State Park of Serra dos Mar SP, Brazil / Influência das variações micro-ambientais na comunidade de palmeiras da floresta ombrófila densa montana, Núcleo Santa Virgínia, Parque Estadual da Serra do Mar SP
O trabalho foi realizado na Floresta Ombrófila Densa Montana (Núcleo Santa Virgínia - Parque Estadual da Serra do Mar, São Paulo, situado entre 2317 a 2324S e 4503 a 4511W), com o objetivo de avaliar como as variações micro-ambientais de solo, liteira e topografia influenciam a composição e estrutura da comunidade de palmeiras. Em duas parcelas perma

10. O bambu Merostachys fischeriana (Bambusoideae: Bambuseae) como habitat para formigas de Floresta Tropical Montana
Although Merostachys fischeriana is very abundant in the Brazilian Atlantic Rainforest, little attention has been paid to the biological interactions with other animals. The present study describes some of the interactions between ants and this bamboo species. The experiment was carried out in a fragment of a montane tropical forest in the Parque Estadual do

11. Characterization of the shrub and tree vegetation from Montane Ombrophilous Dense Forest fragments / Caracterização da vegetação arbustivo-arborea de fragmentos de Floresta Ombrofila Densa Montana
The Atlantic Forest possesses enormous biodiversity and is highlighted by the high floristic diversity and endemism in some plant groups. The Atlantic Forest is among the most endangered tropical forests in the world and most of its remnants are small and altered fragments, or larger areas in mountains, with pronounced slope. Knowledge of the forest remnants

12. ASSEMBLÉIAS DE FORMIGAS DO PARQUE ESTADUAL DO ITACOLOMI (MG) E RELAÇÕES INTRA E INTERESPECÍFICAS ENTRE ESPÉCIES DOMINANTES
Arboreal ants usually show a strong territolialist behavior, defending aggressively their foraging sites or the area surrounding their nest against individuals of other colonies. Thereby, the most aggressive ants with larger distribution, which may be considered dominants, defines the ant assemblage structure by shaping species distributions into threedimens
