Caracterização de efluentes de viveiros de engorda de rã-touro (lithobates catesbeianus, Shaw, 1802)

Aim: Current analysis characterizes the effluent from bullfrog-rearing ponds during the grow-out phase; Methods: Temperature, pH, dissolved oxygen, electric conductivity, turbidity, total phosphorus, N-NH3, N-NO3, BOD5 and COD and the number of thermotolerant coliforms (Escherichia coli) of the inlet and outlet water of the ponds were analyzed twice a week. Assay consisted of a completely randomized experimental design with two treatments (inlet and outlet water) and six repetitions in a split-plot, coupled to collection over time as subplot; Results: All variables were significantly different (p < 0.05) between treatments and over time (p < 0.05). Average rates of temperature, pH and dissolved oxygen levels of the supply water were higher when compared to those of the effluent. The other variables such as conductivity, turbidity, total phosphorus, ammonia, nitrate, biological oxygen demand, chemical oxygen demand and E. coli were higher in the effluent when compared to rates in the supply water; Conclusions: The management during grow-out phase caused the deterioration of the water quality, with increasing levels of dissolved nutrients and the number of thermotolerant coliform. Ammonia and phosphorus levels in the effluent, caused by waste food, skin and feces, accelerate the eutrophication process of the receiving water body. Further studies on effluent treatment are required.

Sistemas de produção pesqueira da pescada amarela (Cynoscion acoupa Lacèpede, 1802) e serra (Scomberomorus brasiliensis Collette, Russo & Zavalla-Camin, 1978) no litoral nordeste do Estado do Pará

O Estado do Pará, cujo litoral se estende do Cabo do Norte à foz do rio Gurupi, representa o principal pólo pesqueiro da região. Dentre as espécies de importância econômica no estado, destaca-se a pescada amarela Cynoscion acoupa e serra Scomberomorus brasiliensis, capturadas principalmente nos municípios de Augusto Corrêa, Bragança, Curuçá, São Caetano de Odivelas, São João de Pirabas e Vigia. Este trabalho teve o objetivo de descrever estes sistemas pesqueiros segundo as dimensões sociais, tecnológicas, econômicas e ecológicos visando estabelecer linhas de ação que auxiliem na estruturação de um plano de manejo que garanta a sustentabilidade das pescarias. Para descrever os sistemas de pesca, uma lista de 45 atributos, na forma de valores numéricos absolutos ou porcentagens, classificados de acordo com cada dimensão supracitada. Um estudo mais aprofundado (Estudo de Caso) foi efetuado em Bragança, para ambos sistemas. Análise multivariada de agrupamento e ordenação (MDS), comparando os sistemas pesqueiros e considerando os diferentes municípios, foram aplicadas, visando identificar os agrupamentos e as possíveis causas da semelhança entre os sistemas de pesca por município. A análise dos sistemas da pescada amarela e serra juntas, mostraram a formação de dois grupos. Quando analisados por dimensão separadamente, registrou-se similaridade entre ambos os sistemas nas dimensões social e ecológica. Com relação às dimensões tecnológica e econômica notou-se que os municípios de Bragança e Vigia (sistema pescada amarela) destacaram-se, sobretudo pelas embarcações utilizadas, tamanho das redes de pesca, produção por pescaria e lucro líquido obtido nas pescarias. Para a serra registrou-se, entre os municípios do sistema, a predominância de barcos de pequeno porte nas capturas. O estudo de caso em Bragança indicou que apesar da importância do grude (bexiga natatória) na cadeia de comercialização da pescada amarela, com elevado valor de comercialização, a venda da carne constituiu a principal fonte de lucro líquido. O estudo de caso da serra revelou que as suas pescarias em Bragança ocorreram em três áreas distintas: costa do Amapá, costa de Salinas e costa de Bragança. Considerando o exposto, pressupõe-se que um plano de manejo no âmbito social deve prover ações em prol da cidadania, saúde, educação, emprego e capacitação. Numa abordagem ecológica, considerando que ambos os estoques se encontram no limite máximo sustentável, medidas de manejo devem ser implementadas. Finalmente, com relação aos aspectos tecnológicos e econômicos observou-se que as pescarias em Bragança e Vigia foram visualmente “sustentáveis”. Entretanto, os acentuados aumentos nas capturas com evidentes tendências de queda na produção, devem ser observados com cautela no que diz respeito à liberação de novos financiamentos.

Oxygen consumption by the hermit crab, Clibanarius vittatus (Bosc, 1802) in declining oxygen tensions

1. 1. Oxygen consumption and its relationship to stepwise declining oxygen tension were examined in the common striped hermit crab, Clibanarius vittatus. 2. 2. Weight-specific oxygen consumption varied with body weight (W), according to the equation log V ̇o2 = 2.1639 + (-0.419 log W). 3. 3. Shell-less individuals of 1-2 g wet wt, where found to be oxygen conformers, since oxygen consumption ( V ̇o2) decreased with declining oxygen tensions. At ambient oxygen tensions below 35.4 mmHg, oxygen consumption remained constant, suggesting an increased ventilation. 4. 4. C. vittatus was found to survive in oxygen-free seawater for 5.5 hr, and no significant differences were found in oxygen consumption rates, for shelled and shell-less crabs, measured in water and air. 5. 5. The use of a K1 K2 index of oxygen independence, showed that larger animals were better able to maintain oxygen-independence during hypoxia than smaller individuals. 6. 6. C. vittatus displayed a pattern of no oxygen debt, once returned to normoxia. © 1983.

Molecular barcode and morphological analyses reveal the taxonomic and biogeographical status of the striped-legged hermit crab species Clibanarius sclopetarius (Herbst, 1796) and Clibanarius vittatus (Bosc, 1802) (Decapoda: Diogenidae)

The taxonomic status of the species Clibanarius sclopetarius (Herbst, 1796) and Clibanarius vittatus (Bosc, 1802), which have sympatric biogeographical distributions restricted to the western Atlantic Ocean, is based only on differences in the colour pattern of the walking legs of adults. Their morphological similarity led to the suggestion that they be synonymised. In order to investigate this hypothesis, we included species of Clibanarius Dana, 1892 in a molecular phylogenetic analysis of partial sequences of the mitochondrial 16S rDNA gene and the COI barcode region. In addition, we combined the molecular results with morphological observations obtained from several samples of these two species. The genetic divergences of the 16S rDNA and COI sequences between C. sclopetarius and C. vittatus ranged from 4.5 to 5.9% and 9.4 to 11.9%, which did not justify their synonymisation. Differences in the telson morphology, chela ornamentation, and coloration of the eyestalks and antennal peduncle provided support for the separation of the two species. Another interesting result was a considerable genetic difference found between populations of C. vittatus from Brazil and the Gulf of Mexico, which may indicate the existence of two homonymous species.

Low temperatures reduce skin healing in the Jacaré do Pantanal (Caiman yacare, Daudin 1802)

Studies of skin wound healing in crocodilians are necessary given the frequent occurrence of cannibalism in intensive farming systems. Air temperature affects tissue recovery because crocodilians are ectothermic. Therefore, the kinetics of skin wound healing in Caiman yacare were examined at temperatures of 33°C and 23°C. Sixteen caiman were selected and divided into two groups of eight maintained at 23°C or 33°C. The studied individuals' scars were photographed after 1, 2, 3, 7, 15 and 30 days of the experimental conditions, and samples were collected for histological processing after 3, 7, 15 and 30 days. Macroscopically, the blood clot (heterophilic granuloma) noticeably remained in place covering the wound longer for the caiman kept at 23°C. Microscopically, the temperature of 23°C slowed epidermal migration and skin repair. Comparatively, new blood vessels, labeled using von Willebrand factor (vWF) antibody staining, were more frequently found in the scars of the 33°C group. The collagen fibers in the dermis were denser in the 33°C treatment. Considering the delayed healing at 23°C, producers are recommended to keep wounded animals at 33°C, especially when tanks are cold, to enable rapid wound closure and better repair of collagen fibers because such lesions tend to compromise the use of their skin as leather.

Räumliche und zeitliche Einbindung einer strukturierten Population der Westlichen Smaragdeidechse (Lacerta bilineata, DAUDIN 1802) im Mittelrheintal

In der vorliegenden Arbeit wurde die räumliche und zeitliche Dynamik einer strukturierten Population der Westlichen Smaragdeidechse (DAUDIN, 1802) im Mittelrheintal zwischen 1997 und 2000 untersucht. Dazu wurden die Teilaspekte der Hibernation, der Thermoregulation und der Raumnutzung der Art analysiert. Die Ergebnisse der Hibernation deuten auf eine hohe Relevanz dieses Jahresabschnitts für die Art in Bezug auf die Verbreitung in Südexponierten Steilhanglagen am Nordrand ihrer Verbreitung hin. Die Hibernationsstandorte unterscheiden sich im Mikroklimaprofil von Trockenmauern und Sommerlöchern. Die Standorte der Hibernation liegen in Zonen höchster Insolation im Untersuchungsgebiet. Die Analyse der Thermoregulation zeigte geschlechtsspezifische und saisonale Unterschiede, die mit den unterschiedlichen Jahresaktivitätszyklen erklärt werden können. Die Weibchen zeigen eine engere Bindung an die klimatischen Entwicklungen von Mirkohabitatstrukturen als die Männchen, was mit endogenen Faktoren zusammenhängen könnte. Die Parallelen und Unterschiede zu anderen Arten werden diskutiert. In der Raumnutzung zeigen sich auch Unterschiede zwischen Männchen und Weibchen, die auch mit den unterschiedlichen Jahresaktivitätszyklen erklärt werden können. Im Frühjahr und im Herbst zeigt die Art eine Bindung an Standorte hoher Insolation im Untersuchungsgebiet, im Sommer dagegen keine. In der Gesamtbetrachtung werden die Ergebnisse in Bezug auf das Verbreitungsbild der Art, Schutzaspekte und Schlüsselfaktoren der Habitatqualität diskutiert.

Il racconto russo contemporaneo: Cuvstvo viny di aleksandr snegir?v. Proposta di traduzione.

В начале этой диссертации я решила изучить фигуру русского современного писателя и трудности, с которыми он сталкивался в былые и последнее время. Его путь не был лёгким потому что, исторические и культурные перемены и решении государства, которое всегда старалось его контролировать, очень повлияли на работу русского писателя. Потом, я представила автора книги, которую я переводила и, в частности, я подчеркнула такие детали его стиля, которые его характеризуют как современного русского писателя, не принадлежащего ни к какому литературному течению. Центром моего анализа книги Снегирёва личная точка зрения автора о современности и об ощущениях каждого персонажа, встречающего перемену в своей жизни. Затем, я проанализировала фигуру переводчика, который должен всегда решить как поступить с разными трудностями оригинального текста. Для того, чтобы правильно переводить, это необходимо, чтобы переводчик принял во внимание не только функцию, контекст и стиль текста, который он должен переводить, но он также должен изучить теории важных переводчиков и критиков, которые могут ему помочь и представляют для него точку отсчёта для будущих переводческих решений. Переводчик должен пропустить всю эту информацию через фильтр своего сознания. Я также включила в эту диссертацию главу о биографии автора и его библиографию автора и часть интервью со Снегирёвым, которое происходило в Москве в мае 2015 года. Этот опыт мне позволил принимать более осмысленные решения, когда я переводила книгу Чувство вины, потому что я лучше поняла и автор и его точку зрения о его работе. После этой главы, я включила в эту диссертацию комментарии к моему переводу, где я привела примеры трудностей и характеристик текста и разные приемы, которые я использовала для того, чтобы разрешить мои сомнения в переводе некоторых частей книги. В заключении я написала главу, в которой я сделала выводы о моей работе по поводу перевода этой книги. В приложение я включила свой перевод на итальянский книги Снегирёва.

Eugene Onegin As A Bridge Between Worlds: Aleksandr Pushkin As Translator Of The 19Th-Century Russian Experience

In my thesis, I use literary criticism, knowledge of Russian, and elements of translation theory to study the seminal poet of the Russian literary tradition ¿ Aleksandr Pushkin. In his most famous work, Eugene Onegin, Pushkin explores the cultural and linguistic divide in place at the turn of the 19th century in Russia. Pushkin stands on the peripheries of several colliding worlds; never fully committing to any of them, he acts as a translator between various realms of the 19th-century Russian experience. Through his narrator, he adeptly occupies the voices, styles, and modes of expression of various characters, displaying competency in all realms of Russian life. In examining Tatiana, his heroine, the reader witnesses her development as analogous to the author¿s. At the center of the text stands the act of translation itself: as the narrator ¿translates¿ Tatiana¿s love letter from French to Russian, the author-narrator declares his function as a mediator, not only between languages, but also between cultures, literary canons, social classes, and identities. Tatiana, as both main character and the narrator¿s muse, emerges as the most complex figure in the novel, and her language manifests itself as the most direct and capable of sincerity in the novel. The elements of Russian folklore that are incorporated into her language speak to Pushkin¿s appreciation for the rich Russian folklore tradition. In his exaltation of language considered to be ¿common¿, ¿low¿ speech is juxtaposed with its lofty counterpart; along the way, he incorporates myriad foreign borrowings. An active creator of Russia¿s new literary language, Pushkin traverses linguistic boundaries to synthesize a fragmented Russia. In the process, he creates a work so thoroughly tied to language and entrenched in complex cultural traditions that many scholars have argued for its untranslatability.
