1. Floristic structure and composition of Guadua forests in the Colombian coffee region1
RESUMO Na região cafeeira (900-2.000 m de altitude) dos Andes colombianos, os remanescentes florestais correspondem, principalmente, a fragmentos dominados pela espécie de bambu Guadua angustifolia Kunth (Guadua). Essas florestas altamente fragmentadas são encontradas em paisagens com alto grau de transformação devido à atividade agrícola e à expans�

2. Water pollution: one of the main Limnology challenges in the Anthropocene
Resumo: A humanidade está definindo um novo período geológico. A era do Antropoceno é marcada por mudanças nos processos geológicos, nos regimes hidrológicos, na estrutura da biosfera, dentre outros processos devido às expansões humanas sobre a paisagem ao redor do mundo. A aceleração dos ciclos biogeoquímicos, a grande carga de poluentes nos rec

3. Composition and structure of the frugivorous butterfly community (Lepidoptera: Nymphalidae) at the Serra Azul State Park (PESA), Mato Grosso, Brazil
ABSTRACT Due to the important ecological role of Nymphalidae as consumers of fermented fruits, excrement, exudates of decomposed plants and animals, as well as bioindicators of environmental quality that attract the interest of the general public, this study aimed to characterize the fauna of frugivorous butterflies at the Serra Azul State Park - PESA (Mato

4. Bacterial communities in mining soils and surrounding areas under regeneration process in a former ore mine
Abstract Human activities on the Earth's surface change the landscape of natural ecosystems. Mining practices are one of the most severe human activities, drastically altering the chemical, physical and biological properties of the soil environment. Bacterial communities in soil play an important role in the maintenance of ecological relationships. This work

5. Bird diversity along a gradient of fragmented habitats of the Cerrado
ABSTRACT Understanding the factors that affect biodiversity is of central interest to ecology, and essential to species conservation and ecosystems management. We sampled bird communities in 17 forest fragments in the Cerrado biome, the Central-West region of Brazil. We aimed to know the communities structure pattern and the influence of geographical distanc

6. Population dynamics of the mud crab Panopeus austrobesus Williams, 1983 (Brachyura: Panopeidae) associated with a mussel farm at the southeastern Brazilian coast
Abstract Mussel farms are one of the most important modalities of aquaculture and constitute almost 80% of the total bivalve production in Brazil, representing about 5% of the national production. Brachyuran crabs are common inhabitants of these environments and represent an important link in coastal marine food chains. The aim of this investigation is to de

7. TIPOLOGÍA Y USOS DEL SUELO EN AGROECOSISTEMAS DEL VALLE DEL GUAMUEZ, PUTUMAYO – COLOMBIA
ABSTRACT The objective of this research was to analyze different agroecosystems located in a region of the Departamento de Putumayo (Colombia) and its sociocultural relationship with productive and land conservation contexts, based on the conceptual and methodological aspects of agroecology. A mixed methods study was carried out, and soil testing methodologi

8. Plant diversity in hedgerows amidst Atlantic Forest fragments
Hedgerows are linear structures found in agricultural landscapes that may facilitate dispersal of plants and animals and also serve as habitat. The aim of this study was to investigate the relationships among diversity and ecological traits of woody plants, hedgerow characteristics (size, age, and origin), and the structure of the surrounding Atlantic Forest

9. Bryophytes on rocky outcrops in the caatinga biome: a conservationist perspective
In the state of Paraíba, Brazil, there is an abundance of rocky outcrops, which are typical elements of the semi-arid landscape. Those outcrops provide refuge to species with morphological adaptations to stressful climates and to rare communities of plants, including bryophytes. Nevertheless, there have been no studies of bryophytes in such habitats in the

10. Evaluation of the environmental sustainability of massive forestry fragments of the coastal plain and lower slopes of Bertioga (SP) / Avaliação da sustentabilidade ambiental dos fragmentos de maciços florestais da planície costeira e baixa encosta do município de Bertioga (SP)
The São Paulo coastal zone alternates extensive zones of great diversity of biotopes with others intensively degradated. These characteristics are observed in the municipality of Bertioga and its forest regions localized among Itaguaré and Guaratuba river basins. Due to their special characteristics these basins are denominated Bertioga System. The aim of

11. Efeitos de diferentes matrizes no risco de predação e na movimentação de uma ave florestal / Effects of different matrices at risk of predation and movement of forest bird
Forest fragmentation alters landscape structure and its relationship with organisms, and movement is one of the most affected behaviors. Individuals who are faced with an heterogeneous landscape, composed of habitat and non-habitat areas (i.e., matrix), need to cross the non-habitat matrix in the search for resources. The choice of motion is then made by an
