Variação da atividade locomotora do ermitão Clibanarius Vittatus (BOSC, 1802) em relação à dessecação, na praia dos pescadores, em São Vicente (SP), Brasil

The crustaceans activity of move about could alter in function of the environmental conditions. In the present study, this activity of the hermit crab Clibanarius vittatus was studied in dry and submerged areas of the intertidal region of Pescadores Beach in Sao Vicente (SP), Brazil. In both areas 110 animals (86 of dry and 24 of submerged area) were analyzed and C. vittatus show more activity in the submerged area than in the dry one. The low activity of locomotion presented when exposed to the air, can be due by the stress caused in function of the high temperature and desiccation.

Integrated quality assessment of sediments from harbour areas in Santos-São Vicente Estuarine System, Southern Brazil

Santos-São Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges have constituted the main sources of contaminants to estuarine system. This study aimed to assess the recent status of sediment quality from 5 zones of Port of Santos by applying a lines-of-evidence approach through integrating results of: (1) acute toxicity of whole sediment and chronic toxicity of liquid phases; (2) grain size, organic matter, organic carbon, nitrogen, phosphorus, trace metals, polycyclic aromatic hydrocarbons, linear alkylbenzenes and butyltins; (3) benthic community descriptors. Results revealed a gradient of increasing contamination for metals and organic compounds, alongside with their geochemical carriers. Sediment liquid phases were more toxic compared to whole sediment. Low number of species and individuals indicated the impoverishment of benthic community. The use of site-specific sediment quality guidelines was more appropriate to predict sediment toxicity. The integration of results through Sediment Quality Triad approach and principal component analysis allowed observing the effects of natural stressors and dredging on sediment quality and benthic distribution. Even with recent governmental efforts to control, pollution is still relevant in Port of Santos and a threat to local ecosystems. © 2013 Elsevier Ltd.

Evidence of contamination by oil and oil products in the Santos-São Vicente estuary, São Paulo, Brazil

Different components of the mixed function oxidase (MFO) system and the levels of fluorescent aromatic compounds in bile (FACs) were measured in Cathorops spixii in order to assess the impact of polycyclic aromatic hydrocarbons (PAHs). Fish were sampled in an estuary (Santos/Sao Vicente) with a history of contamination by PAHs, mainly due to the presence of the industrial complex of Cubatao city and of another of low anthropogenic influence (Cananeia) on the Brazilian coast. FACs were higher in fish from the polluted site, and the PAH 5 and 6-ring metabolites were the most frequent - with 14% and 15%, respectively. Levels of the different components of the MFO system showed the same variation profile as the FACs for both estuaries. Therefore, the values found for somatic indexes and biomarkers with data of bile PAH metabolites indicate the presence of organic contaminants, especially in the area subject to the influence of the industrial complex on the Santos/Sao Vicente estuary.

Commercial Sexual Exploitation and Missing Children in the Coastal Region of Sao Paulo State, Brazil

The commercial sexual exploitation of children (CSEC) has emerged as one of the world’s most heinous crimes. The problem affects millions of children worldwide and no country or community is fully immune from its effects. This paper reports first generation research of the relationship that exists between CSEC and the phenomenon of missing children living in and around the coastal regions of the state of Sao Paulo, Brazil, the country’s richest State. Data are reported from interviews and case records of 64 children and adolescents, who were receiving care through a major youth serving non-governmental organization (NGO) located in the coastal city of Sao Vicente. Also, data about missing children and adolescents were collected from Police Reports – a total of 858 Police Reports. In Brazil, prostitution is not a crime itself, however, the exploitation of prostitution is a crime. Therefore, the police have no information about children or adolescents in this situation, they only have information about the clients and exploiters. Thus, this investigation sought to accomplish two objectives: 1) to establish the relationship between missing and sexual exploited children; and 2) to sensitize police and child-serving authorities in both the governmental and nongovernmental sectors to the nature, extent, and seriousness of many unrecognized cases of CSEC and missing children that come to their attention. The observed results indicated that the missing children police report are significantly underestimated. They do not represent the number of children that run away and/or are involved in commercial sexual exploitation.

A importância da música na transmissão de identidade e valores : o caso do grupo Noite de Mindelo : investigação ação através de um concerto pedagógico realizado em São Vicente, Cabo Verde

O propósito deste trabalho consistiu em elaborar uma análise aprofundada da música cabo-verdiana no contexto educativo enquanto expressão artística, identificando e valorizando o seu papel na identidade nacional e descrevendo os fatores que interferem na sua implementação e generalização a todos os níveis do ensino. Tendo como modelo de pesquisa uma investigação-ação e utilizando uma metodologia qualitativa e interpretativa, desenvolvida no contexto da Educação Artística em Cabo Verde a nível formal e informal, realizou-se um concerto pedagógico no Centro Cultural de Mindelo, ilha de São Vicente Cabo Verde. O projeto debruçou-se sobre a análise dos dois principais géneros musicais cabo-verdianos, a Morna e a Coladeira, os grandes compositores e intérpretes destes géneros, no sentido de provocar uma reflexão e inclusão do estudo da Expressão Musical no contexto educativo cabo-verdiano, como disciplina autónoma capaz de despertar o sentimento de identidade e valores que caracterizam uma Nação. A escolha do concerto através da avaliação dos espectadores permitiu concluir que o ensino aprendizagem da Música em Cabo Verde no contexto educativo requer uma outra abordagem, a elaboração de programas, assim como a contratação de docentes competentes para desenvolvimento dos conteúdos. Mindelo, como ilha tradicionalmente artística, está aquém desta referência e impõe a introdução de políticas educativas que possam inverter esta tendência e criar condições adequadas para que os alunos e a população se interiorizem da importância do ensino das Expressões Artísticas como vetores importantes na transmissão de identidade e valores. A prossecução de investigação nesta área e o incentivo ao desenvolvimento desta temática recomendam-se como forma de dar a conhecer os grandes artistas cabo-verdianos, as grandes composições e despertar o interesse no seio das crianças e dos jovens para a importância do estudo das Artes como uma forma lúdica de aprender e uma possibilidade de ser um artista como tantos que cantaram e cantam Cabo Verde.

Purification and characterization of the biological effects of phospholipase A(2) from sea anemone Bunodosoma caissarum

Sea anemones contain a variety of biologically active substances. Bunodosoma caissarum is a sea anemone from the Cnidaria phylum, found only in Brazilian coastal waters. The aim of the present work was to study the biological effects of PLA(2) isolated from the sea anemone B. caissarum on the isolated perfused kidney, the arteriolar mesenteric bed and on insulin secretion. Specimens of B. caissarum were collected from the Sao Vicente Channel on the southern coast of the State of São Paulo, Brazil. Reverse phase HPLC analysis of the crude extract of B. caissarum detected three PLA(2) proteins (named BcPLA(2)1, BCPLA(2)2 and BcPLA(2)3) found to be active in B. caissarum extracts. MALDI-TOF mass spectrometry of BcPLA(2)1 showed one main peak at 14.7 kDa. The N-terminal amino acid sequence of BcPLA(2)1 showed high amino acid sequence identity with PLA(2) group III protein isolated from the Mexican lizard (PA23 HELSU, HELSU, PA22 HELSU) and with the honey bee Apis mellifera (PLA(2) and 1POC_A). In addition, BcPLA(2)1 also showed significant overall homology to bee PLA(2). The enzymatic activity induced by native BCPLA(2)1 (20 mu g/well) was reduced by chemical treatment with p-bromophenacyl bromide (p-BPB) and with morin. BcPLA(2)1 strongly induced insulin secretion in presence of high glucose concentration. In isolated kidney, the PLA(2) from B. caissarum increased the perfusion pressure, renal vascular resistance, urinary flow, glomerular filtration rate, and sodium, potassium and chloride levels of excretion. BcPLA(2)1, however, did not increase the perfusion pressure on the mesenteric vascular bed. In conclusion, PLA(2), a group III phospholipase isolated from the sea anemone B. caissarum, exerted effects on renal function and induced insulin secretion in conditions of high glucose concentration.

SEDIMENT BIOTURBATION POTENTIAL of UCA RAPAX and UCA URUGUAYENSIS AS A RESULT of THEIR FEEDING ACTIVITY

Bioturbation of mangrove sediments by Uca uruguayensis (Nobili, 1901) and U. rapax (Smith, 1870) was compared based on the grain-size composition and organic content in surface sediment around the burrow and feeding pellets in two mangrove zones of the Sao Vicente Estuary, state of São Paulo, Brazil. For each species, 25 burrows with active crabs were selected. All pellets within a 15-cm radius of each burrow were carefully collected; samples of substrate were taken; and the crab occupant was excavated, sexed, and measured for carapace width (CW). The number of spoon-tipped setae on the second maxilliped of each species was estimated; U. uruguayensis showed more of these setae than U. rapax. For both species, the sediment post-processed by feeding activity (feeding pellets) showed a similar increase of coarser fractions and a smaller organic content. However. U. uruguayensis was more efficient in removing organic matter (88.1%) from the sediment than U. rapax (37.5%). These results suggest that different numbers of spoon-tipped setae on the second maxillipeds of the fiddler crabs do not affect the potential for grain-size selection, but result in differing abilities to remove organic matter from the sediment.

Predation on Leptodactylus marmoratus (Anura: Leptodactylidae) by the spider Ctenus medius (Araneae: Ctenidae) in the Atlantic Forest, southeast Brazil.

We report herein a case of predation by the ctenid spider Ctenus medius on a leptodactylid frog Leptodactylus marmoratus, observed in a remnant of the Atlantic Forest, municipality of Sao Vicente, São Paulo state, southeast Brazil. This is the first record of predation by C. medius upon L. marmoratus. Nevertheless, due to the high abundance of both groups, we suggest that the interaction between spiders and amphibians could be very common on the floor of the Atlantic Forest.
