1. PLANT RICHNESS AND LIFE FORM DIVERSITY ALONG VEGETATION AND FOREST USE GRADIENTS IN NORTHWESTERN PATAGONIA OF ARGENTINA
ABSTRACT The imbalace between the increase in the demand and the decrease in the supply of products from natural forests, partly explains the on-going development of exotic tree plantations. In northwestern Patagonia of Argentina, Pinus ponderosa (Pinaceae) afforestation plays a key role in ameliorate degraded soils, but may also reduce biodiversity. The eco

2. PAYMENT FOR ENVIRONMENTAL SERVICES: GUIDELINES FOR IDENTIFYING PRIORITY AREAS FOCUSING ON BIODIVERSITY*
Resumo O instrumento econômico de Pagamento por Serviços Ambientais (PSA) tem sido considerado uma alternativa para a conservação da biodiversidade e dos serviços ecossistêmicos em terras privadas. Com a finalidade de orientar os tomadores de decisão no processo de implantação de esquemas de PSA, este artigo teve por objetivo identificar na literatu

3. Soil Seed Banks in a Forest Under Restoration and in a Reference Ecosystem in Southeastern Brazil
ABSTRACT The current study aims to characterize the soil seed banks in a forest under restoration and in a seasonal semideciduous forest remnant, as well as to quantitatively and qualitatively compare them in order to evaluate the seed bank potential to influence the restoration process. In total, 60 samples of soil seed banks were collected in two adjacent

4. Metrics of benthic communities and habitat quality associated to different types of land use
RESUMO Os ecossistemas aquáticos estão sob fortes modificações antrópicas. Assim, comunidades biológicas dependentes desses ambientes também são alteradas. O objetivo deste estudo foi investigar os efeitos do desenvolvimento urbano em um ecossistema impactado. Foram selecionadas 15 seções de amostragem ao longo do Ribeirão Vermelho e em cada uma f

5. Effectiveness of Arbuscular Mycorrhizal Fungal Isolates from the Land Uses of Amazon Region in Symbiosis with Cowpea
ABSTRACT Arbuscular mycorrhizal fungi provide several ecosystem services, including increase in plant growth and nutrition. The occurrence, richness, and structure of arbuscular mycorrhizal fungi communities are influenced by human activities, which may affect the functional benefits of these components of the soil biota. In this study, 13 arbuscular mycorrh

6. Assessment of the occurrence and richness of arbuscular mycorrhizal fungal spores by direct analysis of field samples and trap culture - a comparative study
ABSTRACT In this work, we hypothesized that two spore-based methods, direct analysis of field samples and trap cultures, simultaneously used for assessment of occurrence and species richness of arbuscular mycorrhizal fungi (AMF) may vary in their efficiency according to the environmental conditions and the total AMF species richness of the evaluated ecosyste

7. Fatores ecossistêmicos na interface com o cuidado/trabalho da equipe de enfermagem em um Serviço de Pronto Atendimento / Factors of ecosystem in interface with the care/work of the nursing team in an Emergency Care Service
The interest of this study arose from the professional practice of the researcher as a clinical nurse in an Emergency Care Service. It is observed that, generally, the nursing workers are concerned only with the immediate goal; do not show an interest in looking at long-term and of quality and neither visualize the care / work as a whole and therefore they f

8. Mutagênese ambiental: estabelecimento de valores de referência para manguezais da Baía de Ilha Grande / Environmental mutagenesis: establishment of reference valves for mangroves of Ilha Grande Bay
Environmental studies have shown that substances generated by anthropogenic processes can cause adverse effects by interfering with the ecosystem natural balance. Mangroves perform essential functions in biological cycles and are Permanent Protection Area in Brazil. Unfortunately, they are being degraded above its support limit, leading to a reduction of the

9. ECOLOGIA ALIMENTAR DO PEIXE-BOI DA AMAZÔNIA (Trichechus inunguis) (SIRENIA, TRICHECHIDAE) NAS RESERVAS DE DESENVOLVIMENTO SUSTENTÁVEL MAMIRAUÁ E AMANÃ
In order to study the feeding ecology of the Amazonian manatee, we collected 230 fecal samples and analyzed 16 stomach contents of wild manatees during the flooded and low-water periods of the Amazon ecosystem between 1994 and 2008 in the Sustainable Development Reserves of Mamirauá (RDSM) and Amanã (RDSA). The plant species present in the samples were ide

11. Avaliação sanitária da presença de doenças e caracterização dos padrões de caça de subsistência do queixada (Tayassu pecari) de vida livre na Amazônia Peruana / Serologic survey of disease and characterization of subsistence hunting patterns of white lipped peccaries (Tayassu pecari) populations in southwestern Amazon.
The peccary (Tayassu pecari) holds an important place in the Amazonian ecosystem. As seed dispersers they have measurable effects on their habitat, partly guiding structure and composition of the vegetation community. Additionally, their socio-economic role is unsurpassed as one of the most important sources of bushmeat for subsistence hunters in the Peruvia
