1. Capacidade de Retenção de Fósforo e Material Particulado em Suspensão por Manguezal de Área Impactada por Efluentes da Carcinicultura. / Phosphorus retention capacity and Suspension of Particulate Matter in Mangrove Area impacted by effluents from Shrimp.
The mangrove forests stabilize the coastal erosion zone and act as a buffering between the continent and the sea. This forest presents high resilient degree, suggested to be used as marker of environmental changes. They play an important role in the energy flow and nutrients cycles. They are suffering with the growth of shrimp ponds. This tends to be respons

2. Estrutura da comunidade de formas iniciais de peixes em uma gamboa do estuÃrio do rio Catuama, Pernambuco â Brasil
This survey was carried out in a mangrove tidal creek at the Catuama estuary, Pernambuco State, Brazil. With the aim at characterizing the fish community that inhabits these intertidal habitats, samples were taken monthly in day-night periods with an adapted block-net (1mm mesh size at the aisles and 500μm at the core) to catch larvae and young fish in

3. Componentes estruturais abiótico e biótico e caracterização do grau de trofia de gamboas do litoral sul do Paraná, Brasil.
xi Estudos relacionados com a qualidade da água em ambientes costeiros como baías, estuários e gamboas são importantes por serem regiões de alta produtividade e influenciadas por atividades antrópicas. Neste estudo foram avaliadas variáveis físicoquímicas e biológicas em diversas gamboas ao longo da costa do Estado do Paraná. Foram analisadas vari

4. Padrões temporais na assembléia de peixes na gamboa do Sucuriú, Baía de Paranaguá, Brasil
The ichthyofauna of a tidal creek in Rasa da Cotinga Island, Paranaguá Bay, Paraná was studied through monthly collections in the quadrature high and low tides, with seine net of 30 m x 1.5 m and 10 mm mesh and "fyke" net of 30 m x 1.5 m with 10 mm mesh in the wings and 8 mm mesh in the bag. Together with the nekton sampling, temperature, salinity and wate

5. Structure and Dynamics of Fish Assemblages in a Tidal Creek Environment
As amostras foram obtidas mensalmente na baixa-mar de quadratura na Gamboa do Baguaçu, Baía de Paranaguá, Brasil, com uma rede tipo picaré, com malha de 1mm, 30 m de comprimento e 3 m de altura. Foram capturados 30104 peixes pertencentes a 21 famílias e 47 espécies. A espécie Anchoa parva foi a mais abundante, tanto em número como em peso. As captura

6. Seasonal Variability and Transport of Suspended Microfungi in a Southeastern Salt Marsh †
Tidally induced fluctuations and transports of microfungi were investigated. Samples were collected at three depths from three stations positioned at a transect in a large salt marsh creek. Samples were taken every 1.5 h for 50 consecutive h during neap tides and 50 consecutive h during the corresponding spring tides. In each season, microfungi concentration

7. Use of Monodispersed, Fluorescently Labeled Bacteria to Estimate In Situ Protozoan Bacterivory †
We have developed a procedure for preparing monodispersed, fluorescently labeled bacteria (FLB), which may be used to measure virtually instantaneous rates of protozoan bacterivory in natural waters. FLB can be prepared both from natural bacterioplankton assemblages and from clonal isolates and can be stored in frozen suspension or freeze-dried without appar

8. Survival of Escherichia coli and Salmonella spp. in estuarine environments.
Survival of Escherichia coli and Salmonella spp. in estuarine waters was compared over a variety of seasonal temperatures during in situ exposure in diffusion chambers. Sublethal stress was measured by both selective-versus-resuscitative enumeration procedures and an electrochemical detection method. E. coli and Salmonella spp. test suspensions, prepared to

9. Phylogenetic diversity of Archaea in sediment samples from a coastal salt marsh.
The Archaea present in salt marsh sediment samples from a tidal creek and from an adjacent area of vegetative marshland, both of which showed active methanogenesis and sulfate reduction, were sampled by using 16S rRNA gene libraries created with Archaea-specific primers. None of the sequences were the same as reference sequences from cultured taxa, although

10. Comparison of Nitrogen Fixation Activity in Tall and Short Spartina alterniflora Salt Marsh Soils 1
A comparison of the N2 fixers in the tall Spartina alterniflora and short S. alterniflora marsh soils was investigated. Zero-order kinetics and first-order kinetics of acetylene reduction were used to describe the activity of the N2 fixers in marsh soil slurries. It was found that the Vmax values were approximately 10 times greater for the N2 fixers in the t

11. Numerical Dominance and Phylotype Diversity of Marine Rhodobacter Species during Early Colonization of Submerged Surfaces in Coastal Marine Waters as Determined by 16S Ribosomal DNA Sequence Analysis and Fluorescence In Situ Hybridization
Early stages of surface colonization in coastal marine waters appear to be dominated by the marine Rhodobacter group of the α subdivision of the division Proteobacteria (α-Proteobacteria). However, the quantitative contribution of this group to primary surface colonization has not been determined. In this study, glass microscope slides were incubated in a

12. Bacterial Primary Colonization and Early Succession on Surfaces in Marine Waters as Determined by Amplified rRNA Gene Restriction Analysis and Sequence Analysis of 16S rRNA Genes
The nearly universal colonization of surfaces in marine waters by bacteria and the formation of biofilms and biofouling communities have important implications for ecological function and industrial processes. However, the dynamics of surface attachment and colonization in situ, particularly during the early stages of biofilm establishment, are not well unde
