A figura do poeta em Friedrich von Hardenberg (Novalis) e Gaston Bachelard: algumas considerações

Através do Fogo - elemento marcante tanto em Novalis (século XVIII) quanto em Gaston Bachelard (século XX), pudemos ensaiar uma aproximação entre esses dois autores, distantes no tempo, mas próximos no tocante à valorização da imaginação (estética).

Follicular diameter range based on morphological features in Synbranchus marmoratus (Bloch, 1795) (Teleostei, Synbranchiformes, Synbranchidae) from the South-central region of Brazil

The morphological characteristics of Synbranchus marmoratus female germ cells in various development stages were described in details; then measurements of ovarian follicle diameters were taken from primary and secondary growth as during these development stages the oocyte size varied considerably along the fish growth. The results were correlated to total fish length, using the individuals division in six size classes. It was possible to group oocytes by stages according to histological characteristics but not according to morphometric diameter, as there was a wide variation in diameter in each stage and overlap between different maturation stages. These data make available new information on the reproductive biology of Synbranchidae. (c) 2004 Published by Elsevier Ltd.

Reptilia, Squamata, Dipsadidae, Xenodontinae, Taeniophallus brevirostris (Peters, 1863): distribution extension and new state record.

Taeniophallus brevirostris is a dipsadid snake widely distributed in Amazon. Here we report a new Brazilian state record for the species, improving our knowledge of its geographic distribution. 0n 15 May of 2008, one female specimen was collected do Serra do Santo Expediot, Aripuana municipality, state of Mato Grosso, Brazil. This is the first record of this species for the state of Mato Grosso and extends its distribution ca. 300 kilometers from the nearest localities presented in literature.

Juvenile development of Callinectes ornatus Ordway, 1863 (Crustacea : Decapoda : Portunidae), from megalopae obtained in the neuston

The juvenile development of Callinectes ornatus was studied from megalopae collected in the neuston off Ubatuba, São Paulo State, Brazil. The animals were raised in the laboratory under constant temperature (25 +/- 1 degrees C), filtered sea water (35 parts per thousand) from the sampling location, and the natural photoperiod. Eleven stages of the juvenile phase were obtained. The main features of the first juvenile stage diagnostic of the species are: the number of segments in the antenna; number of setae on the exopod, endopod, basal endite and coxal endite of the maxilla, on the exopod, endopod, basal endite, coxal endite and epipod of the 1(st) maxilliped, and on the exopod, endopod and epipod of the 2(nd) maxilliped. Sexual dimorphism becomes apparent from the fourth juvenile stage onwards.

Hermenêutica e anti-hermenêutica: Friedrich Schlegel e Schleiermacher

A fortuna crítica de Friedrich Schlegel é rica em alusões a sua relação com Schleiermacher. Ambos conviveram em Berlim por volta de 1800, época em que Schlegel editava a Athenäum e em que Schleiermacher ainda não escrevera seus principais textos sobre hermenêutica. É possível conceber Friedrich Schlegel como um predecessor de Schleiermacher? Na tentativa de responder a essa pergunta, vamos nos deter sobre três textos, todos eles publicados na Athenäum: o ensaio sobre Lessing (Über Lessing, 1797), o ensaio sobre o Wilhem Meister de Goethe (Über Goethes Wilhelm Meisters Lehrjahre, 1798) e o ensaio da ininteligibilidade (Über die Unverständlichkeit, 1800).

Morfologia dos ovários, tubas uterinas e útero em catetos (Tayassu tajacu, Linnaeus, 1758) e queixadas (Tayassu pecari, Link, 1795)

Estudaram-se a morfologia externa, a sintopia e os dados métricos dos ovários, tubas uterinas e útero em 14 fêmeas adultas de cateto (12 adultas, uma prenhe e uma jovem) e em sete fêmeas de queixada (três jovens e quatro adultas), e o material, após fixação em solução aquosa de formol a 10%, foi dissecado. O material foi obtido na Universidade Federal de Uberlândia (UFU) - Campus Palotina e na Universidade Estadual Paulista - Campus de Ilha Solteira. Os ovários apresentaram-se ovalados e de superfície irregular, quando havia corpo lúteo ou folículo. As tubas uterinas mostraram-se longas, finas e enoveladas e terminando numa extremidade ovárica com fímbrias; a comunicação com o útero ocorreu de maneira contínua. Uma bolsa ovárica parcial, com um largo orifício, contém o ovário. O útero, bicórneo, apresentou um corpo curto e uma cérvix longa, com projeções anulares para o canal cervical, conferindo-lhe luz espiralada. Os cornos uterinos mostraram-se curtos, voltados ventralmente e em forma de hélice.

Vascularização dos ovários, tubas uterinas e útero em catetos (Tayassu tajacu, Linnaeus, 1758) e queixadas (Tayassu pecari, Link, 1795)

Estudou-se a vascularização arterial em nove fêmeas adultas de cateto, incluindo uma jovem e uma gestante, e em seis fêmeas de queixada (três jovens e três adultas). Para este estudo as artérias foram injetadas com solução de látex Neoprene 650 corado e após fixação de formol foram dissecadas. O material foi obtido na Universidade Federal de Uberlândia (UFU) - Campus Palotina e na Universidade Estadual Paulista - Campus de Ilha Solteira. As artérias responsáveis pela irrigação sangüínea dos ovários, tubas uterinas e útero são as artérias útero-ováricas, que emitem as artérias uterinas e ováricas, e as artérias vaginais, estando presentes em todas as amostras, porém variando suas origens. As artérias ováricas emitiram ramos para os ovários, tubas uterinas (ramos tubáricos) e extremidades craniais dos cornos uterinos (ramos tubo-uterinos) e as artérias uterinas enviaram ramos para os cornos uterinos, corpos uterinos e porções craniais da cérvix uterina. As artérias vaginais enviaram ramos para a cérvix e a vagina.

Phylogenetic analysis of the neotropical pseudopolybia de saussure, 1863, with description of the male genitalia of pseudopolybia vespiceps (Hymenoptera : Vespidae, epiponini)

The male genitalia of Pseudopolybia vespiceps are described and compared to congeners. Characters of the male genitalia are combined with morphological characters of the females and nests and used in a phylogenetic analysis. The single cladogram resulting supports monophyly of the genus Pseudopolybia and interrelationships among the species as: P. langi + (P. difficilis + (P. compressa + P. vespiceps)). A new, illustrated identification key is presented.

Fecundity of the crab Callinectes ornatus Ordway, 1863 (Decapoda, Brachyura, Portunidae) from the Ubatuba region, São Paulo, Brazil

The objective of the present study was to characterize the fecundity of Callinectes ornatus from the northern coast of São Paulo, Brazil. To study the fecundity and its relationships to size, brood weight, and egg size, the ovigerous females were collected at 2-month intervals for two consecutive years (January, 1991 to November, 1992) in the Ubatuba region using a fishing boat equipped with an otter-trawl type of net. After collecting, the animals were screened, bagged, labeled, and stored frozen. Only data from 38 females carrying early stage eggs were considered. In the laboratory, the specimens were thawed at room temperature, the pleopod structure with the egg mass was removed and the eggs were carefully removed from the pleopods. The samples were then fixed in 10% formalin and stored in 70% ethanol, until the time for processing. Processing followed the method of Hines (1982, 1988). Following the frequency determination of carapace width and fecundity, mean egg number, mean volume and mean dry weight of brooded egg mass were determined for each class obtained. Data were analyzed by regressions of log-log transformations for allometric plots (Y = aX(b)) of reproductive variables versus carapace width. Carapace width was one of the main factors for the determination of fecundity, which ranged 171 570 +/- 94 634 eggs, with females of the same size class presenting a wide amplitude of variation. This supports the hypothesis that portunid females present staggered spawning, possibly presenting more than one period of reproduction within one year. The present species showed lower fecundity than the remaining portunids studied, but they did show a rapid and efficient embryonic development, presumably capable of assuring reproductive success.

Diel activity rhythm in Callinectes ornatus Ordway, 1863 and Callinectes danae Smith, 1869 (brachyura, portunidae) under laboratory conditions

The locomotory and feeding activity rhythms of Callinectes ornatus Ordway, 1863 and Callinectes danae Smith, 1869 were examined under laboratory conditions. Light significantly influenced the activity of these organisms. However, activity in both species was affected by the presence of food, independently of photoperiod regime.

Histochemical study of muscle fiber types in Synbranchus marmoratus Bloch, 1795

The myotomal muscle of Synbranchus marmoratus was investigated using histochemical and immunohistochemical reactions. This musculature is composed of a superficial red compartment, uniformly distributed around the trunk circumferentially and also in the lateral line. The red compartment fibers are small in diameter and have an oxidative metabolism, a high rate of glycogen and a negative reaction to alkaline and acid myofibrillar ATPase (mATPase). The white muscle forms the bulk of the muscle mass. Its fibers are large in diameter and have a glycolytic metabolism, a negative reaction to glycogen, a strong reaction to alkaline mATPase and a negative reaction to acid mATPase. Between these two compartments there is an intermediate layer of fibers presenting a mosaic metabolism pattern with a high rate of glycogen. These fibers stained moderately for alkaline and acid m-ATPase. Several clusters of red muscles were observed inside the white muscle. Each cluster is composed of three fiber types, with a predominance of red and intermediate fibers. Reactivity to anti-MHC BA-D5 was positive only in the intermediate fibers. Reactivity to anti-MHC SC-71 was negative in all fiber types.
