1. Comparação entre variáveis microclimáticas de local aberto e florestal em um bioma da Mata Atlântica, sul do Brasil
Resumo Na região subtropical do Brasil, o ambiente é naturalmente caracterizado pelo clima quente e úmido. Essas condições são fatores preponderantes para a ocorrência da formação florestal na região, o bioma Mata Atlântica. Associa-se que qualquer condição diferente daquela que não seja natural, pode receber de forma diferenciada a condição

2. BEHAVIOR OF PANTANEIRA AND GIROLANDO HEIFERS REARED ON PASTURES IN THE FOUR SEASONS OF THE YEAR
RESUMO O objetivo deste estudo foi avaliar a dinâmica alimentar e fisiológica de novilhas Pantaneira e Girolando criadas em pastagem e a preferência por três tipos de sombras naturais. Foram utilizados 14 animais, sete de cada raça, com peso médio de 328 kg (Pantaneira) e 430 kg (Girolando). O pasto consistia em Panicum maximum. Foi avaliado o comporta

4. Isolated trees with high crown coverage and densities increase pasture seed rain
ABSTRACT Pasture and crop lands restrict seed dispersal near remnant forest fragments, especially by restricting the movements of dispersal agents and limiting propagule dispersal. Some factors can improve seed dispersal in open areas, such as the presence of high numbers of isolated trees in close proximity to forest fragments. We sought to determine if: (i

5. Performance and carcass quality of feedlot- or pasture-finished Nellore heifers according to feeding managements in the postweaning phase
The objective of this study was to evaluate the postweaning history of heifers kept on marandu grass pastures with three canopy heights, in a continuous-grazing system, during the rainy period, on feedlot- or pasture finishing. The effects of three canopy heights (15, 25 and 35 cm) associated with two supplements (mineral salt and protein-energy supplement)

6. Production indices for dual purpose cattle in central Brazil
This study examined the effects of crossbreeding low genetic potential cows of Bos indicus origin characterized by Gyr crossed with Holstein-Friesian and Simmental bulls to produce animals in a low input dual purpose system. The farm is situated near Brasilia, in the savannah region of Brazil. The climate of the region is classified as Aw by Köppen. Data wa

7. Características estruturais, fitossociológicas e produtividade de um campo sobre basalto supercial / Phytosociological, structural and productivity characteristics of a native pasture on basaltic litolic soil
Few studies had adequately described the characteristics and productive capacity of natural grasslands associated to shallow basaltic soils in Pampa Biome. This study was carried out on natural pasture at Santana do Livramento municipality, in the Campanha region of Rio Grande do Sul, Brazil aiming to describe their floristic and structural diversity and to

8. Efeitos da fragmentação de habitat sobre a comunidade de pequenos mamíferos de Mata Atlântica no Estado de São Paulo / Effects of habitat fragmentation on community of the Atlantic forest small mammals in São Paulo State
The negative effects of habitat fragmentation on small-mammals are widely recognized. Nevertheless, the intensity of these effects depend on multiple factors such as the pattern of fragmentation, the evaluated scale, the permeability of different types of matrices, and the behavioral plasticity of different groups of species. In this study, we evaluated the

9. Alteração no uso e cobertura do solo na bacia do médio rio Araguaia, Brasil central / Land use land and cover changes in the middle Araguaia river basin, central Brazil
The central region of the Araguaia river basin encompasses a transition area between the Tropical Rain Forest and the Cerrado in Brazil. Despite of the fact that during the last four decades, this area has undergone an intense deforestation process, the quantification and impact of these changes are still unknown. Thus this study aimed to evaluate the dynami

10. Dispersal and survival of Nyssomyia intermedia and Nyssomyia neivai (Diptera: Psychodidae: Phlebotominae) in a cutaneous leishmaniasis endemic area of the speleological province of the Ribeira Valley, state of São Paulo, Brazil
The dispersal and survival of the phlebotomines Nyssomyia intermedia and Nyssomyia neivai (both implicated as vectors of the cutaneous leishmaniasis agent) in an endemic area was investigated using a capture-mark-release technique in five experiments from August-December 2003 in municipality of Iporanga, state of São Paulo, Brazil. A total of 1,749 males an

11. Soil quality of cultivated and native pastures systems in the Nhecolandia sub-region, South Pantanal Wetlands. / Qualidade do solo em sistemas de pastagens cultivada e nativa na sub-regiÃo da NhecolÃndia, Pantanal Sul Mato-Grossense
The Pantanal is one of the planetâs largest continuous wetlands areas and where fauna and flora of outstanding beauty and abundance develops. Favored by the richness of natural resources, beef cattle raising, conducted in extensive raising systems, constitutes the chief economic activity. However, the search for yield increases and greater competitivity of

12. Soil quality in native forest and pasture eco-systems in the eastern Acre region of Western Amazon / Qualidade do solo em ecossistemas de mata nativa e pastagens na região leste do Acre, Amazônia Ocidental
The state of Acre is presently at the initial stage of converting its forests into pastures. Around 12% of its total area (19.200 km2) has been deforested. Out of this, approximately 81% (13.352 km2) have been utilized by several productive segments in Acre (farmers, land settlers, extractivists, riverine farmers and cattle producers), with extensive pasture
