1. Mortality of primates due to roads and power lines in two forest patches in Bangladesh
ABSTRACT Primates are in imminent risk of extinction due to different types of anthropogenic activities. Mortality due to road accidents and electrocution from power lines are among the major direct anthropogenic threats to the survival of primates. We collected primate mortality data from 2015 to 2017 at Lawachara National Park and Satchari National Park in

2. Wild pig (Sus scrofa L.) occupancy patterns in the Brazilian Atlantic forest
Resumo: Apesar dos grandes impactos da invasão do javali (Sus scrofa) nos ecossistemas naturais, o uso de hábitats por esta espécie nos neotrópicos ainda permanece pouco estudado. Aqui, nós investigamos os efeitos do hábitat local e de covariáveis da paisagem (tipos de vegetação, cursos d'água e estradas) sobre os padrões de ocupação do javali n

4. Soil Stabilization with Lime for the Construction of Forest Roads
ABSTRACT The mechanical performance of soil stabilization using lime to improve forest roads was assessed. This study was conducted with lateritic soil (LVAd30) using lime content of 2% in the municipality of Niquelândia, Goiás state, Brazil. Geotechnical tests of soil characterization, compaction, and mechanical strength were performed applying different

5. Análise e planejamento da floresta urbana enquanto elemento da infraestrutura verde: estudo aplicado à Bacia do Córrego Judas / Maria Joaquina, São Paulo / Analysis and planning of the urban forest as part of the green Infrastructure: study applied to the watershed of the Stream Judas / Maria Joaquina at São Paulo City, Brazil.
This dissertation develops a design proposal of the Green Infrastructure of the São Judas / Maria Joaquina\ s stream watershed, as a way to promote the increase of the tree cover, and of the public green spaces as well as the connectivity between areas that provide ecosystem services. A study of the Urban Forest - the main component of the Green Infrastruct

6. Optimización del costo del sistema de aprovechamiento de madera en bosques naturales de Pinus caribaea
The work was carried out in natural forests of Pinus caribaea in areas of the forest company "La Palma" in the province of Pinar del Río in Cuba. The objective of the investigation was to minimize the cost of harvesting by combining the costs of haulage and road and load patio densities. In addition, the study also takes into consideration the interaction o

8. Mammal occurrence and roadkill in two adjacent ecoregions (Atlantic Forest and Cerrado) in south-western Brazil
This paper examines the frequencies of mammal roadkill in two adjacent biogeographic ecoregions (Atlantic Forest and Cerrado) of Brazil. Mammals were recorded during a seven-year period and over 3,900 km of roads, in order to obtain data for frequencies of species in habitats (sites) and frequencies of species killed by cars on roads. Sites (n = 80) within e

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. 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
