2. Population biology of Macrobrachium jelskii (Miers, 1877) (Decapoda, Palaemonidae) from an artificial pond in Bahia, Brazil
Abstract The freshwater prawn Macrobrachium jelskii (Miers, 1877) is widely distributed in South America’s lentic and lotic habitats. We studied the population structure and reproductive biology of the species in the municipality of Cruz das Almas, state of Bahia, Brazil, to supply information on this ecologically and economically relevant species. Samples

3. Influence of season, environment and feeding habits on the enzymatic activity of peptidase and β-glucosidase in the gastrointestinal tract of two Siluriformes fishes (Teleostei)
The enzymatic activities involved in the digestion of proteins and carbohydrates were compared among three organs of the digestive track of two Siluriformes fish species, and between two areas: a reservoir, and an area downriver of it. Our aim was to test the hypothesis that the digestive organs of species with varied feeding habits have different enzymatic

5. Estructura de la comunidad de macroinvertebrados del arroyo Achiras (Córdoba, Argentina): análisis previo a la construcción de una presa
Regulation of rivers and streams modifies parameters that directly influence on the biota. In Achiras-del Gato endorheic basin has completed the construction of a midsize dam that will alter the limnological characteristics of the system and the structure of benthic communities. This study provides the first taxonomic records of macrobenthos of this lotic sy

6. Planktonic diatoms in lotic and lentic environments in the Lago dos Tigres hydrologic system (Britânia, Goiás, Brazil): Coscinodiscophyceae and Fragilariophyceae
A floristic study of Coscinodiscophyceae and Fragilariophyceae in the Lago dos Tigres hydrologic system is presented. Phytoplankton samples were collected with a plankton net (25 µm mesh) at 11 sampling stations, three in lotic areas and eight in lacustrine zones. Eleven species of Coscinodiscophyceae and eight of Fragilariophyceae were identified; descript

7. ASPECTOS MORFOLÓGICOS E ECOLÓGICOS DO PROTISTA CILIADO RHABDOSTYLA CHIRONOMI KAHL, 1933 (CILIOPHORA, PERITRICHIA) EPIBIONTE DE LARVAS DE QUIRONOMÍDEOS EM UM CÓRREGO URBANO DO SUDESTE DO BRASIL
In the present study, both taxonomy and morphology aspects of the epibiont ciliate Rhabdostyla chironomi found in São Pedro stream (Juiz de Fora-MG), as well some ecological aspects of this epibiotic relationship between the peritrich and chironomid larvae from genus Chironomus gr. decorus. The present dissertation is divided into four parts. In the first o

8. Alterations in the nature of the water of the Paraiba do Sul River and its infuence in the potabilization processes in the municipality of Jacarei, State of São Paulo [Brazil] / Alterações na natureza da agua do Rio Paraiba do Sul e sua influencia nos processos de potabilização no municipio de Jacarei, SP
Development standards defined by men bring along a greater demand for natural resources, which may result in the degradation of rivers, compromising their diverse uses, especially the supply of water for human consumption. The purpose of this thesis is to analyze potential alterations of the physical, chemical, microbiological and toxicity characteristics of

9. Environmental constraints structuring fish assemblages in the river Paraíba do Sul watershed: Land use condition, habitat and physico-chemical water quality. / Condicionantes ambientais estruturadoras das assembléias de peixes da bacia do rio Paraíba do Sul: Condição do uso da terra, do habitat físico e qualidade físico-química da água.
Structure and dynamic of the Paraíba do Sul fish assemblages and their relationship with environmental constraints in both regional (e.g. altitude, area of drainage, flow and land use) and local (microhabitat and physico-chemical) scales were studied. A fish sampling programme was carried out in the whole extension of the main channel (1100 km) and in the s

10. Influence of the phreatic aquifer in the nutrient dynamics (nitrogen and phosphorus) in lakes of different hydrodynamic characteristics / Influência do aqüífero freático na dinâmica de nutrientes (nitrogênio e fósforo) em lagoas com diferentes características hidrodinâmicas
The discharge zone of Paranapanema river at Jurumirim reservoir is an area of decreased current velocity associated to a great number of aquatic environments with different hydrodynamic characteristics. To evaluate the influence of the superficial phreatic aquifer in the nutrient dynamics (nitrogen and phosphorus and main cations), three floodplain lakes wit

12. BIOLOGIA POPULACIONAL DO CARANGUEJO DE ÃGUA DOCE Trichodactylus petropolitanus NO CÃRREGO DA MINA, CAÃAPAVA, SP: MONITORAMENTO AMBIENTAL A PARTIR DE ESTUDO DE POPULAÃÃES ANIMAIS / Population biology of the freshwater crab Trichodactylus petropolitanus in the CÃrrego da Mina, CaÃapava, SP: environmental monitoring from animal population studies
The freshwater crab Trichodactylus petropolitanus (GÃldi, 1886), is an endemic Brazilian species with occurrence in the States of Minas Gerais, Rio de Janeiro, SÃo Paulo, Paranà and Santa Catarina, being its distribution widely coincident with the domain of the almost extinct Mata AtlÃntica forest. Besides its importance in the trofic web of lotic system
