Colagem, antropofagia e subversão em Galvez imperador do Acre, de Márcio Souza

O presente trabalho aborda o romance Galvez Imperador do Acre, publicado em 1976, pelo escritor amazonense Márcio Souza, estabelecendo as relações entre o texto literário e as propostas estéticas das vanguardas modernistas, tanto européias quanto brasileiras, propondo, assim, a investigação das relações entre modernismo e pós-modenismo, bem como as relações entre literatura, sociedade, história e cultura. Abordaremos questões como a ressignificação de textos literários ou não em Galvez imperador do Acre por meio do processo de colagem e intertextualidade, as relações entre o romance e o momento histórico que retoma e com aquele em que foi produzido, a operação de retomada do passado de forma crítica e transformadora e as possibilidades de leitura do texto literário com vista a algumas teorias pós-modernistas e pós-colonialistas. Observaremos, assim, a maneira como o mesmo retoma a Belle Époque e a extração do látex na Amazônia e sua estética fragmentária, constituída de diversas citações de autores canônicos, investigando o funcionamento da colagem e da antropofagia como principais ferramentas de denúncia e subversão ao processo cultural de importação de valores europeus vivido pelas capitais amazônicas no momento representado pelo romance e cuja crítica pode ser extrapolada para todo um processo de formação cultural no Brasil e na Amazônia. Para isso, poremos em causa as teorias de Jaques Derrida, Walter Benjamim, Claude Levi-Strauss, Fredric Jameson, Luiz Costa Lima, Antonio Candido, Aijaz Ahmad, Homi Bhabha, Stuart Hall, Canclini, Silviano Santiago, Angel Rama, Linda Hutcheon, Antoine Compagnon, entre outros, afim de, a partir do romance em análise, aprofundarmos a discussão teórica acerca das relações comparativas entre textos literários e entre os Estudos Literários e outros campos de estudo.

O enteado, de Juan Saer: narrativa poética e romance histórico?

Em O enteado (2002), de Juan José Saer, tem-se um velho narrador que conta de forma poética a sua história, uma singular experiência de vida. Quando jovem, ele viajava como grumete num navio que costeava a Bacia do Rio da Prata, quando presenciou o ataque súbito e posterior massacre da tripulação do barco pelos índios da região. Como único sobrevivente da carnificina, é praticamente adotado pelos selvagens, passando a conviver com eles, sem saber ao certo a razão de ter sido poupado. Mas a maneira de viver daqueles índios revelou-se bem estranha, pois eram antropófagos, faziam sexo em grupo (orgias), morriam muito cedo, e a peculiar linguagem que praticavam dificultava o aprendizado da língua, e, conseqüentemente, da própria cultura. Assim, esse livro tacitamente promove um debate sobre a Conquista Hispânica da América, do ponto de vista particular de um narrador que constrói poeticamente a sua visão daquele passado, que não diz respeito a nenhum fato histórico preciso. Mas, enquanto a historicidade desse texto transparece nas suas entrelinhas, a sua imanente poesia define o seu aspecto de prosa poética, senão de narrativa poética, traços que apontam para um possível hibridismo literário nesse romance.

Probiótico na larvicultura de matrinxã, Brycon amazonicus

The aim of this study was to evaluate the growth performance of Brycon amazonicus larvae fed with probiotic consisting of Bacillus subtilis, bioencapsulated in Artemia salina at different doses. Six treatments were used: T0 = control (without probiotic), T2.5 = 2.5 g, T5.0 = 5.0 g, T7.5 = 7.5 g, T10.0 = 10.0 g and T12;5 = 12.5 g per liter of probiotic when fed with A. saline (4h before feeding the larvae); and per kilogram of feed (commercial powder with 40% crude protein) in the next phase. The results showed heterogeneity with regard to growth, indicating that larvae fed with probiotic had no influence on cannibalism.

Effect of prey concentrations and feed training on production of Hoplias lacerdae juvenile

The aim of this work was to investigate the s of daily prey concentration during the first 15 days of active feeding of Hoplias lacerdae larvae, and the juvenile size on the feed training. In the first phase, the larvae received five Artemia nauplii concentrations (P). In the second phase, the juveniles from each treatment were trained to accept formulated diet. Superior growth was related to higher initial daily prey concentrations (900 and 1100 nauplii larvae-1). During feed training, the growth tendency was similar to that verified in the first phase. The lowest values of specific growth rate (SGR) were registered after the introduction of the semi-moist diet used in the feed training. However, the values of SGR recovered along the experiment and similar rates were found among the treatments. Survival, mortality and cannibalism were similar in the different treatments at the end of both phases. It can be concluded that: the prey concentration affects growth of H. lacerdae during the first 15 days of active feeding, and feed training can be initialized with juveniles of about 16 mm of total length.

Maternal care in the Neotropical harvestman Liogonyleptoides tetracanthus (Opiliones: Gonyleptidae)

We describe post-ovipositional maternal care in Liogonyleptoides tetracanthus Mello-Leitao 1932 (Gonyleptinae) and experimentally evaluate the protective role of this behavior against egg predation under laboratory conditions. Females laid 138.8 eggs on average and remained close to the clutch during the entire day. Eggs hatched after 11-15 days and nymphs dispersed from maternal protection after one to two days. Most of the experimental clutches left unattended were entirely consumed by conspecifics in 2-3 days. There was no reduction in egg number in the clutches protected by females. Although biological data are scarce, there are cases of egg hiding, paternal and maternal care within the subfamily Gonyleptinae. This diversity of forms of parental care is unusual when compared to other gonyleptid subfamilies, and future systematic revisions of the polyphyletic Gonyleptinae should include parental care as a potential source of phylogenetic information.

Embryonic development and larval stages of Steindachneridion parahybae (Siluriformes: Pimelodidae) - implications for the conservation and rearing of this endangered Neotropical species

Steindachneridion parahybae is a freshwater catfish endemic to the Paraiba do Sul River and is classified as an endangered Neotropical species. An increasing number of conservation biologists are incorporating morphological and physiological research data to help conservation managers in rescue these endangered species. This study investigated the embryonic and larval development of S. parahybae in captivity, with emphasis in major events during the ontogeny of S. parahybae. Broodstocks were artificially induced to reproduce, and the extrusion occurred 200-255 degree-hours after hormonal induction at 24 degrees C. Larval ontogeny was evaluated every 10 minutes under microscopic/stereomicroscopic using fresh eggs samples. The main embryogenic development stages were identified: zygote, cleavage, including the morula, blastula, gastrula phase, organogenesis, and hatching. The extruded oocytes showed an average diameter of 1.10 +/- 0.10 mm, and after fertilization and hydration of eggs, the average diameter of eggs increased to about 1.90 +/- 0.60 mm, characterized by a large perivitelline space that persisted up to embryo development, the double chorion, and the poles (animal and vegetative). Cell division started about 2 minutes after fertilization (AF), resulting in 2, 4, 8 (4 x 2 arrangement of cells), 16 (4 x 4), 32 (4 x 8) and 64 (2 x 4 x 8) cells. Furthermore, the blastula and gastrula stages followed after these cells divisions. The closed blastopore occurred at 11 h 20 min AF; following the development, the organogenetic stages were identified and subdivided respectively in: early segmentation phase and late segmentation phase. In the early segmentation phase, there was the establishment of the embryonic axis, and it was possible to distinguish between the cephalic and caudal regions; somites, and the optic vesicles developed about 20 h AF. Total hatching occurred at 54 h AF, and the larvae average length was 4.30 +/- 0.70 mm. Gradual yolk sac reduction was observed during the first two days of larval development. The first feeding occurred at the end of the second day. During the larval phase, cannibalism, heterogeneous larval growth and photophobia were also observed. This information will be important in improving the artificial reproduction protocols of S. parahybae in controlled breeding programs.

Costs and benefits of temporary brood desertion in a Neotropical harvestman (Arachnida: Opiliones)

Brood desertion is a life history strategy that allows parents to minimize costs related to parental care and increase their future fecundity. The harvestman Neosadocus maximus is an interesting model organism to study costs and benefits of temporary brood desertion because females abandon their clutches periodically and keep adding eggs to their clutches for some weeks. In this study, we tested if temporary brood desertion (a) imposes a cost to caring females by increasing the risk of egg predation and (b) offers a benefit to caring females by increasing fecundity as a result of increased foraging opportunities. With intensive field observations followed by a model selection approach, we showed that the proportion of consumed eggs was very low during the day and it was not influenced by the frequency of brood desertion. The proportion of consumed eggs was higher at night and it was negatively related to the frequency of brood desertion. However, frequent brood desertion did not result in higher fecundity, measured both as the number of eggs added to the current clutch and the probability of laying a second clutch over the course of the reproductive season. Considering that harvestmen are sensitive to dehydration, brood desertion during the day may attenuate the physiological stress of remaining exposed on the vegetation. Moreover, since brood desertion is higher during the day, when egg predation pressure is lower, caring females could be adjusting their maternal effort to the temporal variation in predation risk, which is regarded as the main cost of brood desertion in ectotherms.
