39. Composition of shrimp populations (Crustacea: Decapoda) in non-vegetated areas of two river islands in a Brazilian Amazon estuary
This study investigates the shrimp found in non-vegetated areas of an estuary of the Amazon River. We ascertained the input of juveniles, species' biometrics and the influence of environmental factors on the abundance of species. The samples were collected monthly, from August 2006 to July 2007, in two places in the estuary, each next to an island. For colle

40. New records of caridean shrimps (Decapoda: Caridea) from shallow water along the northern Yucatan peninsula coasts of México
The northern coast of the Mexican state of Yucatán has only been cursorily sampled in the past, with most of this effort concentrated on the largest coral reef in the Gulf of México, Arrecife Alacranes. The present study reports on recent collections (June 2008 - September 2013) of caridean shrimp in Yucatán, including Arrecife Alacranes and other reefs,

41. Phytophilous caridean shrimps (Atyidae and Palaemonidae) in Salsa river (Canavieiras, Bahia, Brazil)
This paper evaluates the role of three species of macrophytes in the population of caridean shrimps in the Salsa river (Northeastern of Brazil). Results revealed that macrophytes have important functions and directly responsible for modulating the spatial distribution of these shrimp species.

42. Snapping shrimps of the genus Alpheus Fabricius, 1798 from Brazil (Caridea: Alpheidae): updated checklist and key for identification
We provide an updated checklist of the snapping shrimps of the genus Alpheus Fabricius, 1798 (Crustacea: Alpheidae) from the Brazilian coast, as well as a key for their identification. The checklist was based on an exhaustive analysis of the literature published up to now, supported by analysis of material of 24 of the 33 species presently recorded from Braz

43. Evaluation of the feeding habits of Macrobrachium brasiliense (Heller, 1862) in the Curral de Arame stream (Dourados/Mato Grosso Do Sul, Brazil)
Macrobrachium brasiliense is a cosmopolitan shrimp species found in the channel of large rivers, streams, lakes, igapós and upland igarapés and can present diversity in the use of food resources. This study aimed to evaluate the feeding habits according to sex, molt stage, seasonal and spatial variation, and size class. Organisms were collected every three

45. Interações tróficas de peixes marinhos no Estado de São Paulo: banco de dados e comparações espaço-temporais / Trophic interactions of marine fish in the State of São Paulo: database and spatial-temporal comparisons
The marine ecosystems of São Paulo State are under intense anthropic pressure. Considering that trophic studies of fishes are essential to the management of ecosystems and fisheries, a fish stomach content database was built in order to summarize the available data in the region. Primary (unpublished) and secondary (published) data were inserted, representi

47. Instabilidades cinéticas em sistemas eletroquímicos: uma contribuição teórica / Kinetic instabilities in electrochemical systems: a theoretical contribution
Mais que fenômenos exóticos, oscilações de corrente e potencial são bastante comuns em vários sistemas eletroquímicos. Ainda que conhecidos há muito tempo, processos oscilatórios na interface sólido/líquido eletrificada são relativamente pouco investigados sob o ponto de vista teórico. São apresentados nessa Tese dois trabalhos, o primeiro rela

48. Controles da produção primária em um Córrego de Mata Atlântica / Controls of primary production in an Atlantic Rainforest Stream
This dissertation consists of two chapters, each corresponding to an independent study. In an Atlantic Rainforest stream, Rio de Janeiro, Brazil, the effects of herbivores and of environmental controls on periphyton were studied. In the first experiment I tested the effects of the shrimp Potimirim glabra, an ecosystem engineer, on the metabolic parameters of
