Descrição do ciclo gametogênico do ouriço-branco, Tripneustes ventricosus (Lamarck, 1816), no Arquipélago de Fernando de Noronha PE, Brasil

Sea urchins are common benthic organisms on coastal ecosystems of tropical and temperate shallow waters. The impact of sea urchins populations in shore communities is density-dependent, and therefore, knowledge of the life history of these animals is important to understand these interactions. Between 2000 and 2005 a population boom of Tripneustes ventricosus was observed in the Fernando de Noronha Archipelago. In 2004 a research program was started to monitor the population dynamics of T. ventricosus in the archipelago, when it noted a lack of basic information on the biology and reproduction of this species, despite its broad geographic distribution and economic importance in parts of its occurrence. In this context, this work focuses on the reproductive biology of T. ventricosus with emphasis on the description of the gametogenic stages. Between December 2006 and July 2007, ten urchins were collected by snorkeling in two sites of the archipelago, totaling 120 individuals. Gametogenic stages were described for both sexes through microscopic analysis, and were defined as: Recovery, Growing, Premature, Mature and Spawning. Results showed increasing in Gonad index throughout of months of sampling and suggest that the reproductive cycle of the species in the archipelago is annual

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

O púlpito como cátedra: retórica e educação nos sermões do Pe. Antônio Vieira (1608-1697)

This work aims to analyze the relationship among culture, education and rhetoric on the sermons of the Priest Antonio Vieira (1608-1697). It discusses the presence of oratory on the Western teaching since its Greek origins until the formation of the Ratio Studiorum in 17th-century. Brazilian society is defined as baroque and the rhetoric arises as element essential in the elaboration of the social imaginary speeches and, occupying as an essencial element in the elaboration of discursese and social imaginaries, occupying the centre of controversies, about questions like reason and the faith, ethics and the politics, the nature of the Indian and African peoples, even over the own construction of the modern subject. In this context the vieira´s preaching discharges the functions of kerigma (preaching), didachê (education) and politics (action). The research consisted in a finicky reading over five of these sermons that were returned in the presence of different audiences. The pulpit was the cathedra where Vieira used his sermons as a manner of social mobilization that aimed not only teaching a determined knowledge of reality, but altering cruel situations like Indian and poor people slavery in his epoch. Education by Vieira consist in a tension between utopian hopes and urgencies of practice. The rhetorical tradition affirms the interdependence of technical ethics and politics aspects. To know is not enough is necessary to convince and to move, realizating passage from theorical to practical liverly. It presupposes still the preoccupation with the solidity of argumentation and of reasoning, a wide cultural formation, the requirement of a civic ethics and, mainly, the adequacy between content and the specifics of audience

Dimensões e universo das representações sociais de educação ambiental por discentes em Garanhuns-PE

The research aimed at investigating the dimensions and the universe of social representations of environmental education, as well as identifying the senses and meanings Environmental Education. This study admitted as presumption the education and environment dimensions. In this investigation was adopted as reference the dimension or representation scope of Moscovici. One hundred and twenty (120) students from Public Schools of Basic Education participated of this study and moreover three hundred and twenty-three (323) from Higher Education in the area of the UPE-FACETEG. The following questions were admitted: 1) What are the dimensions/categories that exist in the semantic scope of social representations of the environmental education? 2) What are the senses and meanings of environmental education? 3) The student s representations of Basic Education are similar or different from the Higher Education? The software EVOC helped in the organization of semantic scope for construction of the categories, with support of the contents analysis. The justifications are sorted on lexical classes using the software ALCESTE, through of the speech analyses. The free association of words answered the question dimension/categories and its semantic scope, being: a) Nature/Environment; b) values; c) Attitudes; d) Actions; e) Implications; f) Mediation. Six lexical classes were found with its meanings enumerated in this way: 1.Awareness, as a factor of belief for the preservation of nature and society. The students are clamoring for environmental education in the school, emphasizing the importance of awareness in the development of the respect to the environment linking the education and family; 2. The consciousness-knowledge relationship for the environment-nature preservation. 3. The environment and human interventions, in search of indicators of solutions. 4. Nature /background/ environment and its constituting elements, a thinking of values and an acting for mediation. 5. The human-nature interaction in social representations of environmental education and the symbolic-life size. 6. Nature / environment /, values, attitudes, actions, implications, and mediation in nature-man relationships. The groups more representatives according to these lexical classes were, the Basic Education in the class-4, represented exclusively by the Primary and Secondary Education and the class-6 represented by both two the Basic Education (47,37%) and the Higher Education (52,63%) - History, Pedagogy, Psychology, Mathematics, Language and Literature. The classes 4 and 6 are related to the class-3 which in turn is formed by students of Higher Education (Mathematics, Biology, Pedagogy, Psychology, Language and Literature) and Basic Education (Primary and Secondary Education). The Higher Education is most represented by the lexical classes (1, 2 and 5). The class 2 corresponded to 80% of the researched groups. In the class-1 the biggest representation was concerning to the Psychology, Geography, Biology and Language and Literature courses, whereas the class-5 was best represented by Psychology, Biology, Pedagogy, Language and Literature, Geography and History. From the results, one may conclude that the imagery is nature/environment; that life is the symbolic dimension that permeates the whole imaginary, and that preservation, awareness and respect are inserted in the speech that circulate to protect life

Da resistência à ação política, a educação pelo consenso: a ação educativa de Pe. Sabino em Mãe Luiza Natal/RN

This study focuses on a methodology of unchained action by Father Sabino Gentili in Mãe Luiza, suburb of Natal-RN, which has enhanced social participation in what Castells calls project identity. The perception of collective actions, focused on the development of subjects from the perspective of Alain Touraine occurs continuously in a popular neighborhood, whose history marked by conflict mainly related to the resistance in the remaining living space. It is argued that there was an appropriation of resistance identity, which was already present in the community of Mãe Luiza, in order to channel it to create a project identity, through an implicit methodology that has been identified as Pedagogy of Consensus, based on Paulo Freire s concepts of dialogue and participation. Therefore, by means of qualitative research, using tools such as semi-structured interviews and documented sources, we tried to describe the intent of the action of a social actor and the political and educational strategies that motivate the collective action aiming a social change, observing the elements present in this action that allowed the continuity of organizational and participating processes through the dynamics of Mãe Luiza s neighborhood

Distribuição radicular de cultivares de aspargo em áreas irrigadas de Petrolina - PE

A distribuição radicular de duas cultivares de aspargo (New Jersey 220 e UC 157 F1), irrigadas por aspersão convencional, foi avaliada durante o ano de 1997 em solos de textura arenosa, em plantio experimental e comercial, respectivamente, nos Projetos de Irrigação de Bebedouro e Senador Nilo Coelho, em Petrolina (PE). O objetivo foi obter informações do sistema radicular do aspargo, empregando-se os métodos do monolito e do perfil de solo auxiliado pela análise de imagens digitais, para o manejo de solo e água nesse cultivo. Na área experimental, a maior parte da matéria seca, área e comprimento de raízes no perfil de solo e densidade de comprimento radicular foram encontradas até a profundidade de 0,4 m nas duas cultivares, enquanto que na comercial a maior parte da área e comprimento de raízes no perfil do solo estendeu-se até a profundidade de 0,6 m (cv. New Jersey 220). Nesses dois plantios, as raízes das cultivares atingiram a profundidade de 1 m. Na área experimental, a massa seca, a área e o comprimento no perfil de solo, e a densidade de comprimento radicular nas cultivares concentraram-se até a distância de 0,6 m à linha de plantas. No intervalo de diâmetro (d) de raízes 2pectivamente, enquanto que pela análise das imagens, o diâmetro de raízes variou entre 2,4 e 2,6 mm (cv. New Jersey 220) e 2,4 e 3,6 mm (cv. UC 157 F1). As estimativas da distribuição e do diâmetro radicular apresentaram similaridades considerando os métodos empregados.

Ocupação de área e interações de golfinhos-rotadores (Stenella longirostris) com o turismo náutico no Arquipélago de Noronha/PE, Brasil

Several works characterize the presence of spinner dolphins at Fernando de Noronha Archipelago in the Dolphins Bay. Though, the dolphins abidance inside this cove has decreased and a new area has been occupied by the animals to achieve the same behaviors, that are resting, breeding and nursing. This area comprises the Inside Sea northeast border of Fernando s de Noronha Island, including the opposing Middle and Dog shore area, the San Antonio Bay and the Between Islands region. The aim was to characterize the dolphins occupation and describe their interactions with the tourism in this area. Data were collected in 2008 and 2009 through a fixed point observation. The study area was divided into seven sub-areas, recording: presence/absence of dolphins, days abidance endurance, abidance length in each area, estimated number of individuals, dolphins direction and speed of displacement, boats presence, interaction period, monitoring, boats attitude and velocity. The dolphins abidance time displayed the same pattern during both years of study, with the higher occupancy in the Between Islands region. Groups with farther than 200 individuals were more frequent both 2008 (46.2%) and 2009 (42.3%). Thus the displacement s slow speed as the preferred direction towards Rat Island also showed the same pattern in both years. The Between Islands region also presented the boats major abidance near the dolphins groups. Boats moved farther in slow speed (95%) than at high speed (5%). The legislation s compliance for the cetaceans protection occurred in 89.7% of 2.839 interactions between boats and spinners, in which this variable was recorded. Whenever boats moved at a slow speed during the meetings with spinner dolphins groups, animals also moved at a slow speed (n = 337), significantly more than the fast displacements (n = 128) ix or "porpoise" (n = 4) (X2 = 318.543, p = -0.001). When boats quickly passed by groups, a significant difference between the dolphins displacement speeds was observed (X2 = 18.264, p =- 0.001), however, the slow (47%) and fast (47% ) displacements frequency was equal, noted the difference with the porpoise displacements (6%), which had the lowest frequency. Data indicate the establishment of a new occupation pattern of the spinner dolphins at Fernando de Noronha, with the Between Islands area being of great importance to the dolphins habits and currently the main area of the boats meeting with the dolphins, showing the need of new conservation measures in this area

Variações horárias na entrada e saída dos golfinhos-rotadores e sua relação com fatores ambientais, na Baía dos Golfinhos em Fernando de Noronha PE

The dolphins are found in all world s marine environments, except for poles. On Brazil, the major concentration of this animals is on Fernando de Noronha Islands, wich have a tropical climate with two well-defined rainfall seasons: dry and rainy season. The Baía dos Golfinhos, wich is the most crowded piece of dolphins on the archipelago. These research looks for to characterize the circadian rhythms of the spinner dolphin behavior, Stenella longirostris, on the Baía dos Golfinhos occupation, at the Fernando de Noronha islands, Brazil s northeast, according to the fluctuations of environment that they all are inserted. The research was realized daily between 1991 January and 2009 December, with observations from a fixed point up to Mirante dos Golfinhos, located on Baía dos Golfinhos. The data was examined with the PASW Statistics 18 program, up to nonparametric tests, being analyzed on the incoming and out coming time of the spinner dolphins and the relationship with moon phases, the wind incidence, and the rainfall season, the dolphins were inserted. The spinner dolphins diurnal rhythms are influenced by moon phases, the spinner dolphins arrival at Baía dos Golfinhos earlier when it s full moon because of the high luminosity at night cause a bigger food efficiency for these animals. The outgoing time of spinner dolphins didn t show statistic difference between moon phases, despite follows the same pattern for the incoming time. When the spinner dolphins are submitted to bigger wind incidence conditions around the archipelago, the dolphins come early to the Baía dos Golfinhos, since that one is protected from wind that reaches Fernando de Noronha, the spinner dolphins tends to arrive later and leave earlier of the bay because the rain may cause adverse conditions for your rest.

Desenvolvimento dos filhotes de atobas-de-pés-vermelhos (Sula sula) no aquipélego de Fernando de Noronha/PE

Parental care s costs increase with the time spent due to incapacity of parents give assistance to increasing offspring food s requirement. This parental care deficits is crucial to offspring s emancipation that involve abilities development to they survive independently. In this work we observe 16 Red-footed boobies chick (Sula sula) on different stages of development, at area of Parque Nacional Marinho of Fernando de Noronha s archipelago, from August to October of 2005. Our data show the parents presence decrease during chick development and an activity frequency modification, in move and fly, which suggest the emancipation s chick development. We observe also the action of Kleptoparasits and the influence with offspring parental care. Our data show consistency with the literature. However, we consider that studies carried through during the peak of the reproductive station can support the hypothesis of that the conflicts, together with the initial period of development of the flight, can be representative in terms of mortality of chicks for the studied species

Detection of antibody to Toxocara vitulorum perieneteric fluid antigens (Pe) in the colostrum and serum of buffalo calves and cows by Western blotting

Toxocara vitulorum, a nematode parasite in the small intestine of cattle and water buffaloes, causes high morbidity and mortality of 1-3 months old buffalo calves. This research evaluated the specific perieneteric antigens (Pe) reactivity of anti-T. vitulorum-Pe antibody (Tv-Pe-Ab) in both immune sera and colostrum from buffalo cows immediately post-partum from buffalo cows. The presence of Tv-Pe-Ab in sera of buffalo newborn calves was also examined at 1 day before and after suckling the colostrum as well as in sera from naturally infected calves at the beginning and peak of the maximum infection and then again during the period of rejection and post-rejection of the parasite. Pe antigens were characterized for Tv-Pe-Ab by SDS-PAGE and Western blot (WB). The SDS-PAGE showed that Pe contained nine protein bands (11, 14, 31, 38, 58, 76, 88,112 and 165 kDa). All Pe bands were recognized by Tv-Pe-Ab in sera and colostrum of buffalo cows. Only the serum antibodies of buffalo calves at 1 day of age after suckling the colostrum and during the beginning of T. vitulorum infection recognized Pe antigen's nine bands. In contrast, serum antibodies from 1-day-old buffalo calves, taken before suckling colostrum, did not react with any protein band. In suckling calves, which reached peak egg output, rejection and post-rejection stages of the infection, serum Tv-Pe-Ab reactivity with lower molecular weight protein bands (11-76 kDa) was lost and only reactivity with the Pe protein bands of higher molecular weight (88, 112 and 165 kDa) remained.

O sistema de garantia dos direitos da criança e do adolescente: análise da trajetória e do processo de resolubilidade dos casos de violência doméstica sexual em Recife PE (2007-2011)

This work discourses about the child and adolescent s Guaranty System of Rights (GSR), on the intervention in cases of juvenile domestic sexual violence, in Recife. The course (trajectory) is analyzed, where circulate cases of sexual violence, until its resolution, in (GSR). Actually, the violence represents a serious problem of public health. Was thought about the difficulties and the limits that make GSR become a full field of contradictions and challenges for the effectiveness of the children and adolescents rights. Therefore, it was verified the treatments that are developed by GSR, how this system is structured and articulated and how occurs the resolution of the sexual violence cases against children and adolescents. Proceedings of the quantitative and qualitative research were used, was done observation, directed interview and analysis of documents. Thus, the field research was the visits in these institutions: Restauração Hospital, Police Management of the Child and Adolescent (PMCA) three Guardianship Councils, Dom Helder Camara Center of Studies and Social Action (CENDHEC) and the Tribunal of Childhood and Adolescence. The research subjects were seven professionals of GSR. The theoretical discussion is guided in reflections about the children and youth rights, in the violence theme and in the construction and institutionalization process of GSR. In this experiment, was noticed there are many difficulties for working together the GSR, because many obstacles are found when we call the responsible institutions, besides some violence cases happen again. This system is not totally institutionalized and articulated, faces structural problems, material, poorly qualified professionals, underinvestment, low transfer of public resources, among other difficulties, causing many losses in the implementation of public policies that enforce secured rights by legislation

Análise da relação entre apego ao lugar, satisfação e fidelidade dos visitantes em destinos turísticos ambientais: um estudo em Fernando de Noronha/PE

The competition among tourist destinations environmental generates the emergent need to find different strategies to close down if the purpose of delight and retain their visitants. A customer satisfaction, loyalty and the development of attachment to place form a solid compound in search of promotion a tourist destination. This study presents the general objective analysis of the relationship between attachment to place, satisfaction and loyalty of visitors, in the archipelago of Fernando de Noronha / PE. Therefore, a model will be used as reference, where they will be analyzed various constructs related to attachment to place, satisfaction and loyalty, as well as the relations between them. The methodology used in the study consists of an exploratory, descriptive, where the sample is random and consists of individuals who visited Fernando de Noronha on a pre-defined period of ten days. Based on a sample table, we defined a quantitative equivalent of 246 questionnaires, which will be applied when the visitor leaves the destination, the departure lounge of airport. A proposal focuses on the possibility to get results able to understand the subjective and intriguing relationship that involves the triad attachment to place, satisfaction and loyalty, trying to thus provide subsidies for optimizing environmental tourist destination

Estudo da atividade sísmica em São Caetano-PE em 2007

In this dissertation we studied the seismic activity in the São Caetano county, Pernambuco State, Northeastern Brazil, located near the Pernambuco Lineament. The Pernambuco Lineament is a one of Neoproterozoic continental-scale shear zones that deforms the Borborema province. The seismicity estudied occurred in a NE trending branch of Pernambuco Lineament. The seismic activity in São Caetano started in 2006 and in May 20th, 2006 a 4,0 mb earthquake hit there. This was the largest earthquake ever reported in Pernambuco State. This dissertation is the result of a campaign done in the period from Februay 1th 2007 to July 31 th 2007. In this campaign up to nine three-component digital seismographic stations were deployed and the collected data was used to determine hypocenters and focal mechanism. A total of 214 earthquakes, recorded at least by three stations, were analyzed. To determine hypocenters and time origin the HYPO71 program was used assuming a half-space model with parameters : VP (P-wave velocity) equal to 5.90 km/s and the ratio VP/VS 1.70, where VS is the S-wave velocity. The earthquakes hypocentral distribution was approximately 4 km long and agrees with the NE-SW direction of the Pernambuco Lineamento branch. Hypocentres depth range from 2 to 8 km. The composed focal mechanism was made from a group of 14 selected earthquakes. We try firstly to find the fault plane solution matching the polarity distribution at stations, using the FPFIT program. The result was 43 deg ± 15 deg for strike, 59 deg ± 9 deg for dip and -142 deg ± 15 deg for rake. We also fitted a plane using the hypocentral distribution to obtain the dip and azimuth of the hypocentral distribution. The results obtained by this fit were 58 deg for the azimuth, 55 deg for the dip and -155 deg for rake. This result shows a mechanism of a strike-slip dextral fault with a normal component. This dissertation shows, once more, that there is a good correlation between the seismic activity and geological features in the region near the Pernambuco Lineament and its NE branches
