Dieta do ouriço-branco, Tripneustes ventricosus (Lamarck, 1816), no Arquipélago de Fernando de Noronha, PE

Sea urchins are benthic macroinvertebrates that inhabit shallow coastal waters in tropical and temperate zones. Urchins are usually classified as generalists or omnivores as they can adjust their diet according to the food resources available in the environment. Due to the strong grazing pressure they may exert, urchins have an important role in marine ecosystems, occupying different trophic levels and stimulating the intensification of the dynamics of communities where they occur. In 2004, a monitoring program focused on the population dynamics of the white sea urchin, Tripneustes ventricosus, has been initiated in the Fernando de Noronha Archipelago. At the same time, a surprisingly lack of information on the species biology has been noted, despite their wide geographical distribution and economic importance in many parts of its range. Hence, this work was developed to provide information on the feeding habits of T. ventricosus in the archipelago. Ten specimens were collected between December 2006 and July 2007 at two sites of the archipelago, Air France and Sueste Bay for biometrics and analysis of gut contents. Test diameters ranged from 9.19 cm (± 1.1) to 10.08 cm (± 0.58). Calculated stomach repletion index (IRE) was higher (p <0.05) in the Air France site and also during January and July. The IRE was not correlated to the gonad index. Fifteen different species of algae were detected in a total of 120 stomachs examined: 4 Chlorophytas, 4 Phaeophytas and 6 Rhodophytas. Food diversity (p <0.05) was higher in December 2006 and January 2007. Although several items had a high frequency of occurrence, they were low represented in terms of weight, and consequently, had a low level of relative importance. The brown algae Dictyopteris spp and Dictyota spp, followed by the green algae Caulerpa verticillata accounted for the greatest importance in T. ventricosus diet, comprising about 90% of the consumed items

Análise do comportamento e crescimento do camarão branco Litopenaeus vannamei (Boone, 1931) em diferentes substratos inconsolidados

The aim of this study was to test the sediment preference of L. vannamei shrimp. It was observed shrimp visit frequency, swimming and burying behaviour at different sediment compositions for 24h. Juvenile (0.93 ± 0.29g) and sub-adult shrimps (10.0 ± 1.18g) were obtained from the aquaculture station at Universidade Federal Rural do Semi-Árido UFERSA, and held in a plastic tank (water volume 500 L) supplied with aerated water and kept at constant temperature, pH, and salinity. Shrimp was fed by commercial shrimp dry food. The experimental substrates were composed by A: medium sand + thick sand + very thick sand + gravel; B: very fine sand + fine sand; and C: silt + clay. Thus, six different substrate combinations were tested: A, B, C, A+B, A+C, B+C. To test preference, it was used a cylindrical tank (40 l) divided into six differently substrate compartments. A single shrimp was introduced each tank and the frequency at which this shrimp visited each compartment was recorded over a 24h study period. It was tested 54 shrimp (18 sub-adult males, 18 subadult females and 18 juveniles). For each trial, sediment and water were changed to avoid pheromones and residues influence. Shrimp were weighted and sub-adults were divided by sex: males present petasma and females present thelycum. Data were collected on the experimental day at 19:30; 20:30; 00:30; 1:30; 05:30; 06:30; 13:30 and 14:30 h. At each time point, shrimp were observed for 20-min periods, in which we noted down which compartment the shrimp was occupying at 2-min intervals. Thus, for each period we had eleven observations (88 observations per day). For observations at night, it was used dim red light that did not affect shrimp behaviour. At each 20-min period, it was observed visit frequency in each substrate, if shrimp was burred or not or if it was swimming. There was not significant difference between light and dark burry activity for females. Swimming activity was significantly higher at night, mainly at 00:30 and 01:30 h. All L. vannamei shrimp showed preference for sediment B. This animal presents cyclic activity, spends the day light period buried and swims at night

Processo biotecnológico voltado a produção de estoques poliploides do camarão-branco litopenaeus vannamei (decapoda, penaeidae)

without practical results so far. Protocols used in biotechnological cultured aquatic organisms aimed at increasing growth rates and disease resistance, have been studied and perfected. Among the available techniques, the application of chromosomal manipulation, although still nascent, is presented as a tool aimed at mitigating ecological and economical issues in shrimp farming. The polyploidization artificial method already employed in fish and shellfish, has been widely researched for use in farmed shrimp. Some limitations of this method of expansion in shrimp refer to a better knowledge of cytogenetic aspects, the level of sexual dimorphism and performance in growing conditions. To contribute on some of these issues, the present study aimed to characterize cytogenetic species Litopenaeus vannamei (Decapoda) and Artemia franciscana (Anostraca), analyze the effectiveness of methods for detection of ploidy, through the use of flow cytometry in processes of induction polyploidy cold thermal shock at different stages of development of newly fertilized eggs. Additionally, aimed also the qualitative and quantitative comparison of larval development between diploid and polyploid organisms, besides the identification of sexual dimorphism in L. vannamei, through geometric morphometrics. The results provide information relevant to the improvement and widespread use of biotechnological methods applied toward national productivity in shrimp farming

Greve do voto: a política da antipolítica nas eleições municipais de 2004 em Fortaleza

This study discusses the use of communication strategies in the dispute for political hegemony in the contemporary society. In order to do so, one starts from the concept of politics in its broad sense, involving, besides parties and parliaments, the groups and organized social movements. The comprehension that the political activity, nowadays, involves the media, made part of this study be focused on the investigation of problems in this relationship. We analyzed, especially, the communication actions promoted by the Grupo Crítica Radical, in which participate, among others, Maria Luiza Fontenelle, former mayor of Fortaleza, and Rosa da Fonseca, former concillor. They left their old parties after a process of self-criticism concerning their incumbencies, partly influenced by the books of Robert Kurz about the collapse of capitalism . After this historical contextualization, one starts the analysis of the campaign Greve do Voto promoted by the Group during the municipal elections of 2004. The production of campaign material, the street drama, the small shows and the fact that the press covered the campaign are discussed starting from the theoretical formulations presented on this research, understanding, this way, the challenge of these groups to build an action against the hegemony allied to the universe of the mass media

Rejeição e voto em eleição contemporânea: um estudo de caso da eleição à prefeitura do município de Natal/RN (2012)

Given the importance that political science and social sciences give studies of voting behavior, this study sought to fill this academic discussion another important element that makes up this complex set. From the campaign trail to City Christmas in 2012 work has been undertaken analysis of rejection in the first and second rounds of this election. For this analysis we used two sources of data: quantitative research, conducted by Search Consult the first and second rounds of elections, and the use of focus group technique, performed in the second round of elections. Knowing the various factors that may affect the voting decision, but also the dynamism that pervades a political dispute, seek, with this work, contribute to the deepening of the rejection of studies, aiming to bring subsidies presenting information to better explain the behavior studies election. The results showed that there is a less expressive, the chamda strong rejection. We speak of that rejection based on a political, historical and ideological. The reason for the weak presence of strong rejection seems to be little involvement of voters with politics and, consequently, low knowledge about politics and politicians. We observe, however, evidence of rejection volatile. We refer here to a kind of rejection that develops during the election process depending on the preference of the voter and according to the circumstances of the campaign. The data also lead us to conclude that television is as an instrument for the dissemination of ideas that can contribute in shaping the opinion of viewers. The role of political parties in representing the interests of the people have lost their strength in recent years. The data also show that, to the extent that increases the preference of voters in the electoral process, also increases its rejection

O voto e seus enigmas: A dimensão subjetiva das escolhas eleitorais

Ce travail analyse la portée subjective des Choix Électoraux à travers la notion psychanalytique du désarroi humain. Nous avons développé cette recherche ayant pour référence la pensée de Freud et de Lacan et suivant les jalons posés par les penseurs des sciences sociales nous nous sommes rapprochées de la réalité sociale pour y « atteindre sur son horizon la subjectivité de notre époque ». La condition de désarroi fait partie de la structuration du sujet, du fait qu il dépend entièrement de l Autre pour se construire. Cependant l être humain se crée des mécanismes pour se protéger du désarroi absolu, il trouve des arts de vivre qui lui rendent plus facile sa condition d être. Les idéaux, les pactes sociaux ce sont des modalités de sécurité sans lesquelles le sujet fixe ses particularités sans s engager dans le processus civilisatoire. Nous caractérisons la société contemporaine par la chute successive d une série d idéaux qui fait monter de plus en plus le désarroi. Dans l absence d idéaux sociaux et politiques sur lesquels l électeur puisse se repérer, nous remaquons une tendance vers l individualisme et vers l absence d investissements dans des projets colectifs. Cette façon d opérer se dévoile aussi au moment de choisir un candidat, ce qui se base sur la logique du particulier motivée par des perspectives individuelles, sans liens avec la promotion de la vie publique. Notre enquête a été réalisée à Natal durant la campagne électorale de 2002. Notre objectif est de comprendre surtout la logique des choix électoraux de la population de la périphérie, celle qui se trouve devant un double désarroi : celle de sa condition humaine et celle qu advient de la précaire condition de subsistance. Nous soutenons que l idée selon laquelle le candidat, par la position qu il occupe dans la société, détient la fonction d offrir quelques garanties à l électeur et de cette manière il entre dans la série de ce qui peut soulager et promouvoir un certain réconfort aux personnes, même si l on considère le fait que l électeur ne croit plus à ses représentants. Nous sommes partis des questions suivantes: comment identifier la dimension subjective des choix électoraux et de quelle manière celle-ci se manifeste-t-elle de nos jours ? Comment se passe le choix éléctoral de la population qui est à la marge du système? La thèse que nous soutenons est que l état de désarroi est un substrat subjectif qui est la base de tout choix éléctoral mais qui se configure de façon différenciée à partir des références de l électeur, de son contexte historique, des facteurs économiques, etc. Le sujet, face à son désarroi, construit des chemins pour pouvoir soutenir son existence ce que nous appellons ici un Projet Directionnel. Ce facteur directionnel est l un des éléments de motivation des électeurs dans leurs choix électoraux

O Barão do Rio Branco no Itamaraty (1902-1912)

Os cem anos do fim da gestão do Barão do Rio Branco no Ministério das Relações Exteriores do Brasil coincidem com um momento politicamente propício para se revisitar o legado do patrono da diplomacia brasileira, em especial o referente aos Estados Unidos e ao Prata, os dois principais eixos das relações externas do País. Examinam-se o teor das relações com a potência hegemônica do hemisfério e o caráter oscilante daquelas com a Argentina. A partir de fontes primárias e bibliográficas, o autor procura demonstrar que Rio Branco, além do fechamento dos limites do território nacional, firmou tendências e procedimentos que se incorporaram à tradição da diplomacia brasileira, analisando, para isso, a função do alinhamento Rio de Janeiro-Washington no conjunto da política externa do chanceler e o padrão das relações com o governo argentino, fatores que influenciaram seus movimentos no entorno geográfico. A política de prestígio desenvolvida por Rio Branco decorreu da aspiração em diferenciar seu país do conjunto de nações do segmento sul do hemisfério, identificadas com convulsões políticas e insolvência financeira.

Medicinal plants used by "Passo da Ilha" rural community in the city of Pato Branco, southern Brazil

O objetivo deste trabalho foi resgatar e documentar o conhecimento popular referente às plantas medicinais utilizadas na comunidade rural do Passo da Ilha, em Pato Branco-PR (26° 11' S, 52°36' W e 760 m de altitude). Optou-se por utilizar o modelo de entrevista estruturada com 16 informantes, os quais possuíam o conhecimento sobre o uso das plantas medicinais em suas famílias. O período da realização das entrevistas foi de outubro a dezembro de 2000. As plantas foram coletadas no campo, identificadas e vouchers foram depositados no Herbário Irina Delanova de Gemtchjnicov (BOTU) da Universidade Estadual Paulista, em Botucatu-SP. Foram identificadas 47 famílias botânicas e 114 espécies de plantas medicinais. Estas plantas foram indicadas para mais de 30 usos medicinais diferentes. A comunidade é composta na maioria por descendentes de europeus, justificando a presença de muitas plantas exóticas. O domínio do uso das plantas é feminino, porém o conhecimento é menor nas gerações mais novas, denotando um processo de erosão cultural.

Vertical distribution of zooplankton in the water column of Lago Amapá, Rio Branco, Acre, Brazil

O objetivo desta investigação foi observar a distribuição vertical da comunidade do zooplâncton no Lago Amapá (10º2'36S e 67º50'24W), localizado na planície de inundação do Rio Acre. Amostragens foram conduzidas em três diferentes profundidades da coluna da água, considerando aspectos sazonais do zooplâncton, parâmetros físicos, químicos e biológicos. Coletas foram realizadas semanalmente com Garrafa de Van Dorn. As espécies apresentaram maiores concentrações no meio da coluna da água. Foram encontradas 38 espécies, assim distribuídas: Rotifera (30), Cladocera (5) e Cyclopoida (3). A temperatura da coluna da água em geral apresentou-se alta, em torno de 30ºC, com pequena variação, resultando em baixa viscosidade. O índice de Jaccard, comparando-se as três estações de coletas, demonstrou que durante a fase de águas baixas, as estações 1 e 3 foram as mais similares (Cj = 0.7058), especialmente no meio da coluna da água. Lago Amapá apresentou características em conformidade com o Modelo do Distúrbio Intermediário, favorecendo a colonização de grupos oportunistas, tais como rotíferos.
