1. Colonization-related functional traits of plants in a 50-hectare plot of secondary tropical forest
ABSTRACT The growth-survival trade-off hypothesis states that functional traits of stem, wood, leaves and fruits govern acquisitive and conservative strategies of plant species that grow/survive differently in forests. We aimed to determine whether heterogeneity during the colonization of a secondary Atlantic Forest fragment causes differences in colonizatio

2. Habitat use, fruit consumption, and population density of the black-headed night monkey, Aotus nigriceps, in southeastern Peru
ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their ecology, describing considerable variation in habitat, group composition, and population density. Therefore, we analyzed habitat use, group com

4. Flora do Rio de Janeiro: Lemnoideae (Araceae)
Resumo Lemnoideae (Araceae) são ervas aquáticas flutuantes, extremamente reduzidas. Subcosmopolitas, geralmente são encontradas em ambientes lênticos de regiões tropicais. No Brasil ocorrem 15 espécies. Este estudo deslindou a subfamília Lemnoideae no estado do Rio de Janeiro, com base em trabalhos de campo e visitas a herbários. Foram registradas on

5. ORGANIC MATTER AND SOIL FERTILITY IN DIFFERENT SUCCESSIONAL STAGES OF SEASONAL SEMIDECIDUAL FOREST
RESUMO O acúmulo e as transformações da matéria orgânica do solo são fundamentais para a manutenção e melhoria dos atributos químicos, físicos e biológicos do solo, e, consequentemente, para o funcionamento das florestas tropicais. O objetivo deste estudo foi avaliar a influência de florestas secundárias com diferentes estádios sucessionais na

6. Small-scale Management of Secondary Forests in the Brazilian Atlantic Forest
ABSTRACT Sustainable management of tropical and subtropical secondary forests for multiple purposes, including timber, may encourage farmers to promote regeneration of native forest. We studied the population structures and commercial timber production in two adjacent 33 years-old Brazilian Atlantic Forest stands: a 26 ha forest managed through enrichment w

7. Avian Communities in the Amazonian Cangas Vegetation: Biogeographic Affinities, Components of Beta-Diversity and Conservation
ABSTRACT The Amazonian cangas is a vegetation type distributed as patches of open vegetation embedded in a matrix of tropical forest and that grows over iron-rich soils in the Serra dos Carajás region. To characterize cangas avifauna, we surveyed birds in eight patches varying from 43 to 1,366 hectares. Cangas avifauna has compositional affinities with sava

8. Phosphorus Forms in Ultisol Submitted to Burning and Trituration of Vegetation in Eastern Amazon
ABSTRACT The use of fire to prepare agricultural areas is a technique still used by small farmers in eastern Amazon. This type of management changes the dynamics of soil nutrients, especially phosphorus, which constitutes the most limiting nutrient for crop production in tropical soils. This study was carried out to evaluate changes in phosphorus forms in an

9. Composition of bat assemblages (Mammalia: Chiroptera) in tropical riparian forests
Various studies have focused on the richness and abundance of bats in tropical forests and how the composition of these forests affects bat assemblages, but there are few studies on the relationship of bats with riparian forests. The aim of this study was to ascertain the differences among bat assemblages of three riparian forest areas of the Tinguá region,

10. Fluctuating asymmetry of and herbivory on Poincianella pyramidalis (Tul.) L.P. Queiroz (Fabaceae) in pasture and secondary tropical dry forest
Plants subjected to stressful environments tend to be more asymmetric with reduced defenses and are therefore more vulnerable to herbivory. This study investigates the relationship between herbivory and fluctuating asymmetry (FA) in Poincianella pyramidalis in two contrasting habitat types in the Brazilian caatinga (shrublands). We tested the following hypot

11. Arthropod responses to the experimental isolation of Amazonian forest fragments
Arthropods are the most diverse and abundant group of animals found in tropical lowland forests, and in light of ongoing global change phenomena, it is essential to better understand their responses to anthropogenic disturbances. Here we present a review of arthropod responses to forest deforestation and fragmentation based on studies conducted at the Biolog
