1. ICMS Ecológico e desmatamento nos municípios prioritários do estado do Pará
Resumo O ICMS Ecológico consiste no dimensionamento, segundo critérios ambientais, de parte dos repasses da parcela do Imposto sobre Circulação de Mercadorias e Serviços que cabe aos municípios. A política se presta à compensação e incentivo de ações favoráveis ao meio ambiente e foi introduzida no Pará com o objetivo explícito de contribuir p

2. Deforestation Dynamics in the Nova Bonal Sustainable Development Project, Acre, Brazil
ABSTRACT This study assessed the dynamics of the land use and cover changes, deforestation trends and the current status of the Legal Forest Reserves (LFR) and Permanent Protected areas (PPA) in the Nova Bonal Sustainable Development Project (SDP) between 1997-2014. Deforestation datasets and fieldwork were used in this analysis. Our results indicate that th

3. Infracommunities of bat flies (Diptera: Streblidae and Nycteribiidae) of bats (Mammalia: Chiroptera) in three conservation units in the State of Amapá, Brazil
Resumo: Dípteros pertencentes as famílias Nycteribiidae e Streblidae são ectoparasitos hematófagos, sendo exclusivamente de morcegos. O estado do Amapá localiza-se na região Norte do Brasil e representa um dos estados com as menores taxas de desmatamento do país, com aproximadamente 80% do território preservado. Dentro do Estado, existem as unidades

4. Post-fire recovery of a dense ombrophylous forest in Amazon
Abstract: The fires that occur in the Amazon are as damaging as the deforestation is. There is a need for further long-term studies on dynamics of tree communities in forests affected by fires. In the present study we evaluated the dynamics of tree species, before and after an accidental fire that occurred in 1997 in an experimental area of terra firme fores

5. Palm species richness, latitudinal gradients, sampling effort, and deforestation in the Amazon region
ABSTRACT Palms are most diverse in warm and humid regions near the equator. Though palms remain relatively well conserved, they are under increasing pressure from deforestation. Here, we analyze patterns of palm species richness relative to latitudinal gradient, sampling effort, and deforestation in the Amazon, and compare patterns of richness and floristic

6. Chagas disease ecoepidemiology and environmental changes in northern Minas Gerais state, Brazil
BACKGROUND Triatoma sordida and Triatoma pseudomaculata are frequently captured triatomine species in the Brazilian savannah and caatinga biomes, respectively, and in Brazilian domiciles. OBJECTIVES This study identified eco-epidemiological changes in Chagas disease in northern Minas Gerais state, Brazil, and considered the influence of environmental shift

7. Influência da estrutura da vegetação de um fragmento florestal nas características físicas e químicas da água e no funcionamento do ecossistema de um córrego rural
Riparian ecosystems are being rapidly degraded due to deforestation for conversion of natural areas to agriculture, pasture, and urban development. In rural areas, riparian forest remnants can be very important for biodiversity conservation and for the maintenance and improvement of water physical and chemical characteristics as the deforested stream passes

8. Adults and tadpoles of species of Hylodidae (Anura): history and taxonomy perspectives
We make a historical review of the rates of descriptions of adult and larval forms of frogs of the three genera of Hylodidae: Crossodactylus Duméril & Bibron, 1841; Hylodes Fitzinger, 1826; and Megaelosia Miranda-Ribeiro, 1923. We analyze and compare the evolution of the number of descriptions of adults and tadpoles of the 42 species presently known in the

9. A relevância das unidades de conservação na proteção de espécies arbóreas ameaçadas de extinção da Mata Atlântica do Sudeste da Bahia / The relevance of conservation units for the protection of tree species threatened by extinction from Atlantic Forest of Southeast of Bahia
A Floresta Atlântica do sudeste da Bahia apresenta uma das maiores riquezas de espécies arbóreas por área do planeta, com uma significativa porcentagem endêmica. Essas espécies encontram-se altamente ameaçadas pelos elevados índices de desmatamento, fragmentação de habitat e corte seletivo decorrente na região. As Unidades de Conservação têm ,

10. Rotational grazing of native pasturelands in the Pantanal: an effective conservation tool.
Deforestation and conversion of native habitats to exotic pasture and crops, plus inefficient agricultural and cattle management practices, are placing great pressures on natural resources in the Pantanal and Cerrado. To prevent further deforestation and protect biodiversity, areas already developed for farming and ranching need to be managed more efficientl

11. A ocorrência de Apiformes (Hymenoptera) em fragmentos da Mata Atlântica e respostas ecológicas para seu desenvolvimento sustentável. / The occurrence of Apiforms (Hymenoptera) in fragments of Atlantic Rainforest and ecological responses for sustainable use.
The high species richness of the Atlantic and Amazon rainforests places Brazil as one of the most important repositories of biological diversity worldwide. Unfortunately, some of these protected areas were rapidly degraded. Deforestation, cattle and agriculture expansion, the spread of exotic species are listed as key factors that mitigate the environmental.

12. 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
