1. Antifungal susceptibility of yeasts isolated from anthropogenic watershed
Abstract Yeasts are unicellular fungi widespread in the environment, and studies suggest that there is a positive correlation between yeast and polluted aquatic environments. The aim of this study was to analyze the diversity and resistance of yeasts isolated from water samples collected along the Arroio Dilúvio in Porto Alegre to antifungals. Yeast isolate

2. CARACTERIZAÇÃO FLORÍSTICA, DIVERSIDADE E CORRELAÇÃO AMBIENTAL NA FLORESTA NACIONAL DE SÃO FRANCISCO DE PAULA, RS / FLORISTIC CHARACTERIZATION, DIVERSITY AND ENVIRONMENTAL CORRELATION IN THE NATIONAL FOREST OF SÃO FRANCISCO DE PAULA, RS
Populations and species are disappearing due to disturbances in the environment caused by human activities. Given the obvious risk of loss of diversity, it is increasingly necessary to take actions concerning preservation, in which safety features are necessary for measuring the variation of diversity in space and time. The aim of this study was to evaluate

3. Padrões florísticos e estruturais das Florestas Estacionais Semideciduais do Triângulo Mineiro, MG / Floristic and structural patterns of semideciduous seasonal forests of Triângulo Mineiro, MG
The semideciduous seasonal forests (SSF) of southeastern Brazil have a high floristic diversity, accompanied by a high beta diversity, even between nearby fragments. However, nowdays these forests have been represented by a large number of small fragments, a landscape pattern typical for this region. In addition to the processes related to fragmentation, the

4. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

5. Identidade florística e estrutura da comunidade arbórea de um trecho de mata ciliar em Paracatu - MG
Realizou-se inventário da comunidade arbórea de um trecho da mata ciliar do rio Paracatu, em Minas Gerais - Brasil, com o intuito de contribuir para o conhecimento ecológico e recuperação das florestas ribeirinhas das bacias do rio Paracatu e do rio São Francisco. O estudo teve como objetivos: 1) avaliar a composição florística, riqueza, diversidade

6. Diversidade e distribuiÃÃo espacial e temporal da Anurofauna (Amphibia, Anura) em fragmento de Mata AtlÃntica de Igarassu, Pernambuco
This study aimed to inventory the species of amphibian anuran, to estimate its diversity, richness and abundance, analyze the spatial and temporal distribution of the species and verify if there is a correlation between the abiotic parameters (temperature, rainfall and humidity of the air) and its richness and abundance in an fragment of the Atlantic Forest

7. Fitossociologia e florística do componente arbóreo em toposseqüência na reserva biológica de Saltinho, Pernambuco.
The forests have these characteristics phytosociological and floristic alter due to the complexity of factors that environment, therefore, study of species-related relief and soils it is necessary for a greater understanding of these relationships. The present work aimed to analyze the structure phytosociological and floristic in the toposequence on a patch

8. Ecologia trÃfica das anÃmonas-do-mar Anthopleura cascaia e Anthopleura krebsi (cnidaria: anthozoa) em duas praias de Pernambuco, Brasil
Studies of trophic ecology are fundamental to understanding the role that the species play in the ecosystem. Sea anemones are important components of reef environments, but few studies address the relationship anemone and its prey. So, it was developed a study on the species Anthopleura cascaia and Anthopleura krebsi on Piedade and Carneiros beach, in Pernam

9. Levantamento florístico e produtividade de macrófitas aquáticas ocorrentes em ambientes limnéticos do Estado de Pernambuco Brasil
A wide variety of aquatic macrophytes can be found on the banks of rivers or reservoirs (sluices and dams). They are important components of these ecosystems, consisting of stock portion of energy and matter in the first trophic level. However, due to the changed environment, some species begin to develop dense infestations,promoting a series of losses, and

10. Diversidade de Scarabaeinae (ColeÃptera: Scarabaeidae) na Caatinga do Parque Nacional do Catimbau, BuÃque - PE
This study aimed to ascertain the Scarabaeinae fauna from Parque Nacional do Catimbau, BuÃque - PE, and assess the response of their communities, in open and closed environments, to the variation pluviometric. The Scarabaeinae (Coleoptera: Scarabaeidae) are considered useful as biological indicators and have been used to investigate the effects of disturban

11. Ecology of zooplanktonic communities associated with palm swamp ponds in Uberlândia, MG / Ecologia de comunidades zooplanctônicas em lagoas associadas a veredas no município de Uberlândia, MG
Ponds of veredas, a palm swamp environment associated with headwaters, appears among the most important continental aquatic habitats on the planet. In these ponds, banks of macrophytes occurs with frequency, maintaining the aquatic productivity and the increase of habitat heterogeneity, thereby generating great biological diversity in their environment. One
