1. Forecasting the impact of an invasive macrophyte species in the littoral zone through aquatic insect species composition
ABSTRACT Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ging

2. From forests to cattail: how does the riparian zone influence stream fish?
O presente estudo verificou se a composição taxonômica e funcional de peixes de riachos varia ao longo de três condições de preservação da zona ripária: preservada (PRE), preservação intermediária (INT) e degradada (DEG). Cinco riachos de cada grupo foram selecionados e amostras foram obtidas em cada riacho em três ocasiões em períodos secos d

3. Limnological aspects of Little AÃudagem in Semiarid: Case Study of Dams Settlement May 25, Ce-Madalena / Aspectos limnolÃgicos da pequena aÃudagem no semiÃrido: estudo de caso dos aÃudes do Assentamento 25 de Maio, Madalena-Ce
The studies for small reservoirs in the semiarid northeast are still scarce, mainly in relation to water quality. This research aimed to discover the dynamic processes that occur in small reservoirs, to evaluate the multiple uses, the trophic state and water quality in small reservoirs representing the settlement on May 25. Carried out the systematic monitor

4. Influence of the riparian zone phytophysiognomies on the longitudinal distribution of fishes: evidence from a Brazilian savanna stream
São descritas a estrutura e composição da comunidade de peixes em um riacho afluente do rio Aquidauana, localizado na região planáltica da bacia do rio Paraguai, centro-oeste do Brasil, com atenção especial aos efeitos diferenciais das fitofisionomias de Cerrado predominantes nas zonas ripárias ao longo do seu gradiente longitudinal. Foram capturados

5. Relação solo-vegetação em mata ciliar do Rio Gualaxo do Norte, município de Mariana, Minas Gerais / Relationship soil-vegetation in riparian forest of River Gualaxo do Norte, municipal district of Mariana, Minas Gerais
The objetctives of this work were to study the floristics and phytossociologic structure of the arboreous vegetation of a section of riparian forest in the River Gualaxo do Norte, to determine the distribution of arboreous species of the riparian could be correlated with soil factors and to indicate species for the reclamation of riparian forests, to verify

6. Factors structuring fish assemblages in three distinct zones (river, mixture and coastal) of the rio Mambucaba estuary, Angra dos Reis-RJ. / Fatores estruturadores das assembléias de peixes em três distintas zonas (rio, mistura e costeira) do estuário do rio Mambucaba, Angra dos Reis- RJ.
The estuarine systems influence fish assemblages, throughout their longitudinal gradients and remarkable salinity changes. Such assemblages adapt to different habitat constraints and change in spatial and temporal scales. The aim of this study was to assess the ichthyofauna composition and structure in three zones of the Mambucaba estuary (CZ coastal zone; M

7. Monitoramento e modelagem de processos hidrogeomorfológicos : mecanismos de geração de escoamento e conectividade hidrológica
This dissertation discusses the runoff generation mechanisms and hydrological connectivity, based on monitoring and modeling of hydrogeomorphologic processes in the Saci Experimental Watershed (10 ha) completely covered with forest and located within the municipality of Rio Negrinho, Santa Catarina State, Brazil. An intensive monitoring system was implemente

8. Socioenvironmental characterization of the residents in the riparian area at the hydrographic basin of the Riozinho do Rôla, Rio Branco, Acre / Caracterização socioambiental de moradores da zona ripária da bacia hidrográfica do Riozinho do Rôla, Rio Branco, Acre
This study was carried out to develop a socioenvironmental characterization of the residents in the riparian zone at the hydrographic basin of the Riozinho do Rôla, Rio Branco - Acre. After two moments for approaching the space and population, some formularies were applied to the riverine families residing along the main watercourse, as well as partially st

9. Relações tróficas e isotópicas entre duas espécies de caracídeos e a cobertura do solo em córregos da bacia do rio Corumbataí, SP / Trophic and isotopic relationships between two species of Characidae and land cover in streams from the Corumbataí River basin, Brazil
Os ecossistemas aquáticos, além de suas complexas relações internas, são intrinsecamente influenciados pelos ambientes terrestres. Baseando-se na hipótese de que a cobertura do solo influencia as dietas de caracídeos nectônicos de córregos, este trabalho teve o objetivo de investigar, através de conteúdos gástricos e da utilização de isótopos

10. Avaliação hidrológica da zona ripária através da análise da água subterrânea ao longo das vertentes de uma microbacia experimental / Hydrology assessment of riparian zone by groundwater analyse through the hillslope in an experimental catchment
Groundwater samples were collected in piezometers located in two transects through the hillslope and two in the headwater of an experimental catchment from May 2005 to April 2006. In each transect there were one piezometer in the upland under the Eucalyptus planted forest, one piezometer at the middle slope in the riparian area, and the other piezometer was

11. The influence of salt spray and the physical and chemical characteristics of the Massaguaçu River Estuary water (Caraguatatuba, São Paulo) on the adjacent vegetation. / Fatores condicionantes da flora marginal e aquática do Estuário do rio Massaguaçu (Caraguatatuba SP).
Both the biotic and abiotic characteristics of a habitat determine which species can live in this habitat. The frontier of two different habitats creates a transition zone, called ecotone. The transition of the Atlantica Forest and the Restinga is normally related to the presence of salt. The salt is a border line for vegetation. In costal habitats, the salt

12. Legal aspects regarding the buffer zone of protected areas: case study of Assis Ecological Station (São Paulo State, Brazil) / Análise dos aspectos jurídicos correlatos à zona de amortecimento de unidades de conservação: estudo de caso da Estação Ecológica de Assis (SP)
Buffer zones of the natural reserves have been considered as the most powerful instrument to prevent environmental impacts to the ecosystems coming from the neighboring areas. Their efficacy, however, is controvertible and that was the subject of the present case study, concerning to Assis Ecological Station, an integrally protected reserve from the Forestry
