1. Abundance and instantaneous transport of Petrolisthes armatus (Gibbes, 1850) planktonic larvae in the Catuama inlet, Northeast Brazil
A influência dos ciclos de maré e fotoperíodo sobre o fluxo de larvas planctônicas de Petrolisthes armatus foi estudada na barra de Catuama, que representa um ambiente intermediário entre os sistemas marinho e estuarino no nordeste do Brasil. Para caracterizar a abundância e a distribuição vertical das larvas, foram feitas coletas em agosto de 2001,

2. Os primeiros estágios de vida da savelha (Brevoortia pectinata) no estuário da Lagoa dos Patos / Early life stages of Argentine menhaden (Brevoortia pectinata) in the Patos Lagoon estuary
Patterns associated to environmental conditions and to the spatial and temporal distributions of the early stages of Argentine menhaden, B. pectinata, and of its development in the Patos Lagoon estuary were investigated using historical records. Two other complementary experiments were performed: one to evaluate the measurement techniques (traditional and im

3. Downstream passage of fish larvae and eggs through a small-sized reservoir, Mucuri river, Brazil
In South America, one important symptom of the failure of fish passages to sustain fish migratory recruitment is the inability of eggs and larvae to reach the nurseries. This is especially so when the breeding areas are located upstream of a reservoir, and the floodplain is downstream of the dam. Therefore, the transport of fish larvae and eggs across reserv

4. Survival of Ucides cordatus (Decapoda: Ocypodidae) megalopae during transport under different conditions of density and duration
Target areas for Ucides cordatus (Linnaeus, 1763) restocking programs are often located far from the laboratory where larval rearing is developed. During translocation, the larvae are submitted to highly stressful conditions due to handling, packing, and transport activities. The aim of the present study was to assess the mortality rates of U. cordatus megal

5. Application of remote sensing to the study of the pelagic spiny lobster larval transport in the Tropical Atlantic
A conectividade de populações marinhas através da dispersão larval é crucial para a manutenção da produção pesqueira e da biodiversidade. A dispersão de larvas ocorre em diferentes escalas espaciais e temporais, de forma que o recobrimento global e escala sinóptica fazem dos dados de satélite ferramentas importantes para esses estudos. O objetivo

6. Purification, partial characterization and role in lipid transport to developing oocytes of a novel lipophorin from the cowpea weevil, Callosobruchus maculatus
Lipid transport in arthropods is achieved by highly specialized lipoproteins, which resemble those described in vertebrate blood. Here we describe purification and characterization of the lipid-apolipoprotein complex, lipophorin (Lp), from adults and larvae of the cowpea weevil Callosobruchus maculatus. We also describe the Lp-mediated lipid transfer to deve

7. Subsidies towards the management of the northern coast of São Paulo State: a case study of the larval settlement success of coastal decapods. / Subsídios para o zoneamento marinho do litoral norte do Estado de São Paulo: um estudo do sucesso do assentamento lerval de decápodos costeiros
O presente estudo foi realizado ao longo de uma linha de costa, incluindo duas enseadas em Ubatuba-SP, Brasil. Os objetivos principais foram: (1) Examinar, em seis costões rochosos, séries temporais de assentamento larval de decápodos, afim de entender forçantes físicas associadas ao transporte em direção à costa, (2) Localizar agregações larvais n

8. Análise da dispersão de larvas de lagostas no Atlântico tropical a partir de correntes geotróficas superficiais derivadas por satélites / Use of geostrophic currents derived from radar altimeter to study lobster larvae dispersion in the tropical atlantic
Three species of spiny lobster are harvested along the Brazilian coast (Panulirus argus, P. laevicauda and P. echinatus). The annual revenue amounts 50 to 60 million US dollars. These species have a relatively long planktonic larval phase (about one year), that enables the mean ocean currents to transport the larvae over long distances away from the original

10. "Modelagem do transporte e retenção larval da anchoíta Engraulis anchoita na plataforma continental do Atlântico Sudoeste" / Modeling the transport success and retention of anchovy (Engraulis anchoita) early stages in the Southwestern South Atlantic Continental Shelf
Nos estudos de populações pesqueiras é comum o uso de modelos hidrodinâmicos acoplados a modelos biológicos e, um tipo de modelo merece destaque: o baseado no indivíduo (IBM). A Plataforma Continental do Atlântico Sudoeste comporta uma importante atividade pesqueira e, a influência da circulação na distribuição de ovos/larvas nessa região é pou

11. Identificação, caracterização e estudo da expressão dos genes hsc70 e hsp83 em Rhynchosciara americana / Identification, characterization and study of expression of the genes hsc70 and hsp83 in Rhynchosciara americana
With the idea of identify some of these proteins involved in the folding process of the proteins synthesized on the Rhynchosciara salivary gland, this project started adopting the shotgun cDNA sequencing strategy. This cDNA library was constructed utilizing salivary glands of Rhynchosciara americana at a developmental period where the cocoon construction beg

12. Kinesin Mutations Cause Motor Neuron Disease Phenotypes by Disrupting Fast Axonal Transport in Drosophila
Previous work has shown that mutation of the gene that encodes the microtubule motor subunit kinesin heavy chain (Khc) in Drosophila inhibits neuronal sodium channel activity, action potentials and neurotransmitter secretion. These physiological defects cause progressive distal paralysis in larvae. To identify the cellular defects that cause these phenotypes
