1. Species diversity, community structure and ecological traits of trees in an upper montane forest, southern Brazil
ABSTRACT Upper montane ecosystems in Brazil are little known, and their structural and functional aspects poorly understood. Our goals were to describe tree species diversity and community structure, and to characterize tree species in relation to their ecological traits, phytogeographic history and conservation status in an upper montane araucaria forest re

2. Ecological aspects of Langsdorffia hypogaea (Balanophoraceae) parasitism in the Pantanal wetlands
Most studies on holoparasitic plants have focused on taxonomic or systematic issues. The objective of this study was to examine the ecological aspects of parasitism of Langsdorffia hypogaea (Balanophoraceae) in the Pantanal wetlands. Individuals of L. hypogaea were dug out by hand and the host trees were identified. Eighty-eight percent of host trees exhibit

3. Tree community dynamics in a submontane forest in southeastern Brazil: growth, recruitment, mortality and changes in species composition over a seven-year period
In order to assess long-term community dynamics in tree populations, we investigated trees with a diameter at breast height (DBH) > 5 cm in an 11-ha fragment of submontane tropical forest in southeastern Brazil, at the beginning and end of a seven-year period. We observed a general tendency toward decreasing numbers of trees and toward stability in basal are

4. Resposta da comunidade de formigas aos atributos dos fragmentos e da vegetação em uma paisagem da Floresta Atlântica nordestina
The objective of this study was to determine the effects of forest fragmentation on ant richness in a landscape of Atlantic Forest in Northeast Brazil. More specifically, the ant richness was related to the attributes of fragments (area and distance from the fragment central point to the edge), landscape (forest cover surrounding the fragments), and tree com

5. Besouros escarabeÃneos em fragmentos de Floresta AtlÃntica do Centro de Endemismo Pernambuco
Habitat fragmentation alters the dynamics of tropical tree assemblages, being able to modify the dung beetles communities. The objective of this research was to determine how the fragments metrics and functional attributes of trees assemblages influence the dung beetles communities in Atlantic forest fragments of northeastern Brazil. The collecting of dung b

6. Floristic composition and phytosociological structure of a seasonal semideciduous forest in Araras, São Paulo state / Composição florística e estrutura fitossociológica de uma floresta estacional semidecidual em Araras, SP
The purpose of this study was to analyze the specific composition of tree, arboreal structure, infestation by climbers, canopy layer and compare the results with other forest fragments and, from these, to form a data bank for monitoring. The forest studied is located in the geographical coordinates S 22 17 and W 47 24. The soil is red-dark Latosoil type and

7. Composição, estrutura e aspectos ecológicos da mata ciliar do Rio Araguari no Triângulo Mineiro / Composition, structure and ecological aspects of forest riparian the Araguari River within Triângulo Mineiro region
The study aimed to characterize the tree-shrub community of a riparian forest, one of the last remnatns on the Araguari River, at Uberlândia, Triângulo Mineiro region, Minas Gerais State. The composition, horizontal and vertical structure were investigated by phytosociological survey of 110 plots of 10m x 10m (1,1ha). All trees with CAP ` 15 cm were regist

8. Formigas cortadeiras (Hymenoptera, Formicidae) como agentes modificadores da disponibilidade de luz e da estrutura da comunidade vegetal em Floresta AtlÃntica Nordestina
Leaf-cutting ants of the genus Atta are important generalist herbivores of the Neotropics, with many species showing a marked preference for early successional plants. Previous studies have revealed that their enormous nest constructions (up to 200 m2) locally affect the abundance and species richness of the plant community. Moreover, leaf harvesting activit

9. Estudo de liquens corticícolas foliosos em um mosaico de vegetação no sul do Brasil / lichens;forest;Araucaria angustifolia
Lichens are important epiphytic components of forests, however anthropogenic alterations of forest habitats could lead to substantial modifications in the diversity and species spatial distribution of lichens. This work investigates how species composition, richness, abundance, diversity and vertical distribution of lichens in tree trunks could be modified w

10. Crescimento e atividade fotossintetica em duas especies de lianas de uma floresta estacional semidecidual
The lianas are copious in natural and man-made clearings and it appears that these forms of life require high irradiance for development and growth. Lianas are rooted in the soil and use other plants, especially trees as support. Since these plants begin their growth on the forest floor, then ascend to the canopy, they can experience extreme differences in r

11. Análise da vegetação arbórea e conservação na Reserva Florestal da Cidade Universitária "Armando de Salles Oliveira", São Paulo, SP / Analysis of arboreal vegetation and conservation at the Forest Reserve of the Cidade Universitária "Armando de Salles Oliveira", São Paulo, SP, Brazil
This work analyses the structure and dynamics, at several spatial and temporal scales, of the arboreal community in the Reserve of the Cidade Universitária "Armando de Salles Oliveira" (CUASO) (23º33 S, 46º43 W), São Paulo, SP. Based on these data, management actions are suggested, aiming at the conservation of the arboreal community at the site. The

12. Directed seed dispersal by bellbirds in a tropical cloud forest
A fundamental goal of plant population ecology is to understand the consequences for plant fitness of seed dispersal by animals. Theories of seed dispersal and tropical forest regeneration suggest that the advantages of seed dispersal for most plants are escape from seed predation near the parent tree and colonization of vacant sites, the locations of which
