1. SPECIES-SPECIFIC EQUATIONS: GREATER PRECISION IN COMMERCIAL VOLUME ESTIMATION IN MANAGED FORESTS IN THE AMAZON
ABSTRACT The objective of this study was to analyze the performance of species-specific equations (SSEs) concerning generic ones in Annual Production Units (GEAPUs) and in a Forest Management Area (GEFMA) in the Brazilian Amazon. A total of 29,119 trees from 43 species were inventoried, harvested, and volumetric measurements were taken in ten APUs, with 10%

2. Diversity of parasitoid wasps in conventional and organic guarana (Paullinia cupana var. sorbilis) cultivation areas in the Brazilian Amazon
RESUMO Pesquisamos vespas parasitoides (Hymenoptera) em duas plantações de guaraná na Amazônia central brasileira (uma convencional e outra manejada organicamente), bem como em florestas adjacentes e áreas de borda entre cultivo e floresta. Avaliamos as diferenças entre os sistemas de manejo na diversidade e abundância de parasitoides e a importância

4. 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

5. Biodiversity Conservation in Agricultural Landscapes: the Importance of the Matrix
ABSTRACT Agricultural matrices can lead to landscape homogenization, culminating in losses of biodiversity and ecosystem services. Agricultural management is determinant for developing conservation strategies. In this review, we discuss the influence of the agricultural matrix on biodiversity at different scales. Intensive agriculture under agrochemicals and

6. Fertilization of Eucalyptus Stands at Advanced Ages in Minas Gerais, Brazil
ABSTRACT This study evaluated the response to fertilization at advanced ages in Eucalyptus stands. Fertilization at advanced ages (FA) was applied in stands managed according to tall shaft and coppice regimes. All stands received operational fertilization from the company. It was used as the basis to the network of continuous forestry inventory plots (P-IFC)

7. Caracterização dos planos de manejo florestal no estado do Piauí
Resumo A lenha é um dos mais importantes produtos florestais da região Nordeste do Brasil, e cada vez mais é necessário que sua exploração seja feita de maneira sustentável. Nesse sentido, o manejo florestal tem sido uma proposta de significativa melhoria das características ambientais dessa atividade. Este trabalho teve como objetivo identificar e a

8. Vegetation Recovery of Logged-over Dipterocarp Forests In Central Kalimantan, Indonesia
ABSTRACT Forest utilization usually has an impact on changes in forest structure and species composition. The species of trees selected and ecosystem management system that refer to biodiversity characteristics will be explained by better knowledge of Functional Species Group (FSG). The purpose of this study was to determine the composition of vegetation rec

9. 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

10. Soil carbon stock and humification in pastures under different levels of intensification in Brazil
ABSTRACT: Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil. This study aimed to evaluate different pasture management options in relation to their effect on soil C stocks and soil organic matter (SOM) humification. Pastures in four beef cattle produc

11. EMISSÕES DE ÓXIDO NITROSO E METANO DO SOLO EM ÁREAS DE RECUPERAÇÃO DE PASTAGENS NA AMAZÔNIA MATOGROSSENSE
AbstractThis study evaluates the chemical processes responsible for the nitrous oxide (N2O) and methane (CH4) fluxes in the managed pasture (PM) and unmanaged pasture (PNM). In addition, the impact of nitrogen fertilization on the N2O and CH4 fluxes was assessed. The experiments were conducted on three farms in Alta Floresta city in the state of Mato Grosso.

12. Padrões de distribuição de mamíferos de médio e grande porte em paisagens fragmentadas / Distribuition patterns of medium and large size mammals in fragmented landscapes
Habitat fragmentation is defined as the breaking of a continuous habitat in patches or fragments. This process leads to environmental changes capable of affecting communities in different ways, causing species composition changes. Beta diversity measures can show the variation between the composition of different communities, where two ecological patterns ca
