1. Anadenanthera Colubrina vell Brenan: anti-Candida and antibiofilm activities, toxicity and therapeutical action
Abstract: We evaluated the antifungal and antibiofilm potential of the hydroalcoholic extract of bark from Anadenanthera colubrina (vell.) Brenan, known as Angico, against Candida spp. Antifungal activity was evaluated using the microdilution technique through the Minimum Inhibitory and Fungicide Concentrations (MIC and MFC). The antibiofilm potential was te

2. Identification of Triterpenoids from Schefflera systyla, Odontadenia puncticulosa and Conostegia speciosa and In Depth Investigation of Their in vitro and in vivo Antifungal Activities
As a part of a broad screening of antifungal agents from plant origin, crude extracts from Panamanian plants having related types of constituents displayed significant activities in an agar overlay thin layer chromatography assay against a susceptible strain of Candida albicans. These were the methanolic extract of the leaves of Schefflera systyla and Odonta

3. Predation on microcrustaceans in evidence: the role of chaoborid larvae and fish in two shallow and small Neotropical reservoirs
This study was focused on the predation upon microcrustaceans by an invertebrate predator (chaoborid larvae), and vertebrate predators (fish), in two small reservoirs in southeastern Brazil, with and without macrophytes, in two climatic periods (dry and rainy seasons). Chaoborus larvae were sampled in the limnetic zone, as they are scarce in the littoral, an

4. 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,

5. Influence of environmental conditions on health of engraulidid larvae collected in Santos (SP) / Influência do ambiente na higidez de larvas de engraulidídeos coletados na região de Santos (SP)
The aim of this study was to analyze influence of environmental conditions on health of engraulidid larvae of the continental shelf off Santos (24º49´S - 23º49´S e 46º55´W - 45º24´W). Samples were collected during two oceanographic cruises (September 2005 and March 2006). Differences among hydrographic conditions were verified between surveys: in Sep

6. 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

8. Abundancia e tamanho das fases larvais de Limnoperna fortunei (DUNKER, 1857) no rio Paraguai e no rio Miranda, MS
Desde sua invas?o na Am?rica do Sul, o mexilh?o dourado se tornou um grande prejuizo para ind?strias hidrel?tricas, locais de tomada de ?gua e embarca??es ao longo dos rios no qual ocorre. O molusco produz larvas durante uma grande parte do ano e isso dificulta ainda mais o seu controle. O presente trabalho apresenta uma an?lise da varia??o mensal na densida

9. Larvas de peixes e invertebrados planctÃnicos coletados com um novo modelo de armadilha de luz: Bahia de Tamandarà - PE
Larval fish and a great number of other planktonic organisms, display photobehavioral characteristics which make possible the use of artificial li-t to attract and capture them. The concept of light traps is not a new concept, and it has been used for a long time by entomologists and limnologists, but introduced to stud reef enviroment by Doherty in 1987. Th

10. G protein and diacylglycerol regulate metamorphosis of planktonic molluscan larvae
The regulatory guanine nucleotide binding protein (G protein) activators cholera toxin and the GTP analog 5-guanylyl imidophosphate, the second messenger diacylglycerol, and certain diamino acids all facilitate (amplify) the settlement and metamorphic responses of planktonic larvae of Haliotis rufescens (marine mollusc) to morphogenetic chemical stimuli. In

11. Developmental shifts and species selection in gastropods
The fossil record of marine gastropods has been used as evidence to support the operation of species selection; namely, that species with limited dispersal differentially increase in numbers because they are more likely to speciate than widely dispersing species. This conclusion is based on a tacit phylogenetic assumption that increases in species with limit
