1. Leaf anatomical traits of non-arboreal savanna species along a gradient of tree encroachment
ABSTRACT In the Brazilian savanna (Cerrado of Brazil), fire suppression has transformed typical savanna formations (TS) into forested savanna (FS) due to the phenomenon of encroachment. Under encroachment, non-arboreal plants begin to receive less light due to greater tree density and canopy closure. Here we aim to evaluate if leaf anatomical traits of non-a

2. The role of terrestrial bromeliads in determining the spatial organization of plant life forms in a tropical coastal forest
ABSTRACT The interplay between plant-plant interactions and light heterogeneity in the understory of tropical forests has rarely been examined. We aimed to identify the relative importance of the understory light environment and terrestrial bromeliads in explaining the abundance and spatial organization of different plant life forms along a coastal forest gr

3. Hypolytrum (Cyperaceae): taxonomic and nomenclatural notes, geographical distribution and conservation status of Neotropical species
Abstract (Hypolytrum (Cyperaceae): taxonomic and nomenclatural notes, geographical distribution and conservation status of Neotropical species.) Hypolytrum (Mapanioideae) is a medium-size and Pantropical genus of Cyperaceae, closely related to Mapania, Principina, and Scirpodendron. In the Neotropics, it is found from southern Mexico to southern Brazil where

4. Structure of the understory community in four stretches of Araucaria forest in the state of São Paulo, Brazil
We analyzed the structure of the understory community in the Atlantic Forest sensu lato, for which phytosociological descriptions of the understory are lacking. We delineated 50 plots of 10 × 20 m each at four sites within an Araucaria forest (a subtype of Atlantic Forest), located in the municipalities of Bananal, Campos do Jordão, Itaberá and Barra do C

5. Vertical structure of an assemblage of bats (Mammalia: Chiroptera) in a fragment of Atlantic Forest in Southern Brazil
Few studies have focused the vertical structure of bat assemblages, and how it influences community composition. The goal of this study was to analyze the vertical structure of an assemblage of bats in a forest fragment in southern Brazil. Bats were sampled using mist-nets placed at three heights (understory, below-canopy, and canopy). Forest strata were com

6. Understory structure in riparian fragments of atlantic rainforest in the extreme north of Pernambuco, Brazil / Estrutura do sub-bosque em fragmentos ripÃrios na floresta atlÃntica do extremo norte, Pernambuco, Brasil
Deleterious changes in fragments of forest communities have been often associated to biotic and abiotic changes related to area and edge effects. The understory is an important component of forest communities and exhibits a clear response to the process of fragmentation, due to its susceptibility to such effects. In the Northern section of the Atlantic Fores

7. Responses of wild titi monkeys, Callicebus coimbrai (Primates: Platyrrhini: Pitheciidae), to the habituation process
Adequate habituation of free-ranging subjects is essential for any field study, but is generally unsystematic. Here, attempts to habituate three titi monkey (Callicebus coimbrai Kobayashi & Langguth, 1999) groups are described, and factors determining the effectiveness of the process are discussed. The "relentless pursuit" approach was aided by playback reco

8. Impact and regeneration mechanism after invasion by Pteridium arachnoideum (Kaulf.) Maxon (Dennstaedtiaceae) in savanna woodland areas, southwestern São Paulo State / Impacto da invasão e mecanismos de regeneração natural do cerradão em áreas ocupadas por Pteridium arachnoideum (kaulf.) Maxon (Dennstaedtiaceae) no sudoeste do Estado de São Paulo
The genus Pteridium comprises bracken species recognized by large fronds and a rhizome system that allows their fast expansion. Bracken presents an elevated biomass production throughout the year, that increases fire occurrence and release chemical compounds that are considered allelopathic. Nowadays, species of the genus Pteridium are well known as problem-

9. Management of lianas in semideciduous forest and cerradão edges, Santa Rita do Passa Quatro, SP / Manejo de lianas em bordas de floresta estacional semidecidual e de cerradão, Santa Rita do Passa Quatro, SP
In São Paulo state, throughout the same climatic zone, semideciduous forests and cerradão patches commonly share the same geographic area. Currently, these two formations are reduced to small fragments, in advanced stage of disturbance. Along with the fragmentation of the forest, there is an increase in ligth incidence at the edges and lianas generally inc

10. DIVERSIDADE DE ÁCAROS EDÁFICOS (ACARI: ORIBATIDA) E REDUÇÃO DO ESFORÇO AMOSTRAL NO GRADIENTE ECOLÓGICO DE 10 MIL HA DE FLORESTA DE TERRA-FIRME DA RESERVA DUCKE, MANAUS, AM, BRASIL
Sampling oribatid mites in large areas using conventional methods is expensive, timeconsuming, and this constrains their use on monitoring program. In 2001/2002, a system of 9 N-S and 9 E-W trails was installed in the reserve. Following the RAPELD method, plots were distributed over a 64 km2 grid of trails spaced 1 km apart, resulting in 72 plots with a mini

11. Tree species community diversity: aplication of taxonomic distinctness indices in three forest phytophysionomies in São Paulo State / Diversidade de espécies em comunidades arbóreas: aplicação de índices de distinção taxonômica em três formações florestais do Estado de São Paulo
This research is part of the project Biota / FAPESP, "Tree Species Biodiversity Inventory Methods, and analised floristic structural differences among three areas. In Assis Ecological Station, Forest Savanna area were sampled 102 species, 72 genus and 43 families, 67% of this species were exclusive of this phytophisiognomy. Semideciduous seasonal forest in t

12. Estrutura, estratificação e grupos ecológicos de um fragmento de floresta estacional semidecidual (Uberaba, MG)
Seasonal semideciduous forests (FES) occur in patches mainly in the region of the Cerrado of central Brazil, had occupied a expressive area throughout Minas Gerais state. These formations generally occur on fertile and humid soil, characterized for the climatic changes that determines the seasonal deciduousness of the dominant tree individuals, in reply the
