1. Relative growth of freshwater prawn Macrobrachium brasiliense (Decapoda, Palaemonidae) and its implications for reproduction
RESUMO O objetivo principal deste estudo foi estimar a maturidade sexual morfológica de Macrobrachium brasiliense (Heller, 1862) e analisar o crescimento relativo da espécie. Durante um ano de coleta, de julho de 2012 a junho de 2013, foram coletados 199 espécimes em um riacho localizado em um bioma de Cerrado, na região do Triângulo Mineiro. Uma vez id

2. Identification of nurseries areas of juvenile Prochilodus lineatus (Valenciennes, 1836) (Characiformes: Prochilodontidae) by scale and otolith morphometry and microchemistry
ABSTRACT The streaked prochilod Prochilodus lineatus (Valenciennes) is a commercially freshwater species from South America, distributed in the Plata basin. In the present work the morphometry (circularity, rectangularity, form factor, OL/OW and ellipticity indices) and chemistry (Sr:Ca, Ba:Ca, Zn:Ca) of lapilli otolith, and geometric morphometry of scales o

3. Fish functional groups in a tropical wetland of the Yucatan Peninsula, Mexico
ABSTRACT The characterization of species' functional traits is a major step in the understanding and description of communities in natural habitats. The classification of species into functional groups is a useful tool to identify redundancy and uniqueness. We studied the fish community of a pristine freshwater wetland in the Sian Ka'an Biosphere Reserve by

4. Diversidade taxonômica e funcional de assembleias de peixes de riachos dos biomas Mata Atlântica, Cerrado e Amazônia
O Brasil é um país privilegiado por possuir uma das ictiofaunas de água doce mais diversificadas em nível mundial, essa enorme biodiversidade está relacionada com uma grande rede hidrográfica composta por um conjunto de bacias e regiões hidrográficas que apresentam características de ecossistemas bastante diferenciados. Muitas dessas bacias se encon

5. Tratamento de efluente anaeróbio : condicionamento em filtro de areia visando lançamento e reúso / Anaerobic effluent treatment : sand filters conditioning to disposal or reuse applications
Increasing scarcity of freshwater due to demographic growing, urbanization and, climate changing are the reason of increasing use of the wastewater in agriculture. Nowadays, this practice is a reality, mainly in São Paulo in the southeast areas, where the conflicts caused by multiples use of water are constant. Based on this situation, the aiming of this in

6. Analysis of environmental sustainability of the superficial freshwater classification system / Análise da sustentabilidade ambiental do sistema de classificação das águas doces superficiais
Brazil is a country endowed with great superficial water reserves and aquatic biodiversity, despite its unequal distribution among diverse hydrographic regions. In view of the sustainable development concept established in many international environment and water treated, objectified to the aquatic ecosystems preservation and the equitable distribution of th

7. Isolation and characterization of the full-length cDNA encoding a member of a novel cytochrome p450 family (CYP320A1) from the tropical freshwater snail, Biomphalaria glabrata, intermediate host for Schistosoma mansoni
Cytochrome p450s (cyp450s) are a family of structurally related proteins, with diverse functions, including steroid synthesis and breakdown of toxins. This paper reports the full-length sequence of a novel cyp450 gene, the first to be isolated from the tropical freshwater snail Biomphalaria glabrata, an important intermediate host of Schistosoma mansoni. The

8. FILOGEOGRAFIA DE Hypopygus lepturus HOEDEMAN, 1962 (GYMNOTIFORMES: RHAMPHICTHYIDAE) AO LONGO DO MÉDIO RIO NEGRO, AMAZÔNIA
The present work was conducted in two chapters: on chapter one a study about the phylogenetic position of the clade Steatogenini (formed by the genus Hypopygus Hoedeman, Stegostenopos Triques, e Steatogenys Boulenger) were carried out based on nuclear and mitochondrial DNA sequences. On chapter two, a study about the genetic differentiation on Hypopygus lept

9. Membrane-bounded nucleoid in the eubacterium Gemmatata obscuriglobus.
The freshwater budding eubacterium Gemmata obscuriglobus possesses a DNA-containing nuclear region that is bounded by two nuclear membranes. The membrane-bounded nature of the nucleoid in this bacterium was shown by thin sectioning of chemically fixed cells, thin sectioning of freeze-substituted cells, and freeze-fracture/freeze-etch. The fibrillar nucleoid

10. A gene phylogeny of the red algae (Rhodophyta) based on plastid rbcL.
A phylogeny for the Rhodophyta has been inferred by parsimony analysis of plastid rbcL sequences representing 81 species, 68 genera, 38 families, and 17 orders of red algae; rbcL encodes the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase. Levels of sequence divergence among species, genera, and families are high in red algae, typically much
