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).

Fecundity of crab Hepatus-pudibundas (herbst, 1785) (crustacea, decapoda, calappidae) in Ubatuba (SP), Brazil

The egg number and the rate in which they are produced constitute important informations for the comprehension of the reproductive process. The egg number carried by a female crab is related to a body dimension (carapace width or length). These data are adjusted to a linear regression. The specimens of Ii. pudibundus were collected in Ubatuba region, Brazil during the period from January 1991 to July 1993. In this paper 30 females with eggs in the initial embryonic phase were used to estimate ther egg number. The mean fecundity obtained was 75,615 +/- 30,120 eggs/female/spawn. Although the H. pudibundus fecundity was not high, it can be inferred that the larval survival in nature should be large, because it is one of the most abundant crabs in the studied area.

Weight width carapace relationship in the crab hepatus-pudibundus (herbst, 1785) (crustacea, decapoda, calappidae) of the Ubatuba region, SP, Brazil

In populational studies, the weight/width carapace relationship analysis, can furnish indications about the individual physiological variations as a function of the environment, and it can indicate sexual dimorphism. The goal of this research is to find the mathematical expressions of weight/width carapace relationship in the crab Hepatus pudibundus. This study was accomplished by analysing the crabs that were sampled monthly with a shrimp fishing boat equipped with 2 otter-trawl nets, during the period from november/1988 to october/1989. A total of 624 specimens were obtained composed of 244 males and 380 females. In each group the sex, the weight (PE) and the carapace width (LC) were determined. The obtained values agree with the studied range, showing variations during male and female development, represented by the potential function of the equation Y = aX(b). Such variations are probably related to reproductive strategies.

Appraisal of the chelipeds size on Hepatus-pudibundus (Herbst, 1785) (Crustacea, Calappidae) in function of sex and maturation

This paper appraises the influence of chelipeds on sexual and maturation phasis of the crab Hepatus pudibundus (Herbst, 1785), collected in Ubatuba (SP) region. The allometric constants obtained from the regression (carapace width X cheliped weight) adjusted to a power function (Y=aX(b)) were analysed. It was verified that males show larger chelipeds than females. The mean percentage of the chelipeds weight differs in sex and maturation.

LOSS OF HEMISPERMATOPHORES AND SEXUAL-BEHAVIOR OF TITYUS-BAHIENSIS (PERTY, 1834) (SCORPIONES, BUTHIDAE)

Male scorpions (Tityus bahiensis) that have been deprived of their hemispermatophores and hemispermatophore sheaths retain their ability to court females despite their inability to mate successfully. Although hemispermatophores usually regenerate rapidly in nature, no such regeneration occurred after experimental amputation.

LARVAL DEVELOPMENT OF THE SPIDER CRAB ACANTHONYX-PETIVERII EDWARDS,H.MILNE, 1834 (DECAPODA, MAJIDAE) IN THE LABORATORY

The larval development of Acanthonyx petiverii H. M. Edwards, 1834, was studied in the laboratory through eggs hatched from ovigerous females collected in Ubatuba, state of São Paulo, Brazil. The rearings were carried out in a climatic room with constant temperature (25 degrees +/- 1 degrees C) and salinity (34,5 parts per thousand). The larvae were maintained individually and the food consisted of Artemia nauplii. The larval development of A. petiverii consists of two zoeal stages and a megalopa. All the larval stages were drawn and described in detail. Tables include those presenting morphological characters that allow the identification of zoeae and megalopa of A. petiverii. A comparative study was realized with previously studied majid species that occur in southern and southeastern Brazil.

Larval development of Epialtus bituperculatus H. Milne Edwards, 1834 (Crustacea: Decapoda: Brachyura: Majidae) with comments on majid larvae from the southwestern Atlantic

The larval development of the spider crab Epialtus bituberculatus H. Milne Edwards which lives on rocky shores with algae such as Sargassum and Hypeneia, is described. Larvae were obtained from ovigerous females collected in Ubatuba, State of São Paulo, Brazil. Rearing was carried out at 24 ± 1°C, with an average salinity of 35%. Larval development consists of two zoeal stages and one megalopa. Zoeal development was completed in 9.5 days. Analysis indicated that zoeae of E. bituberculatus are very similar to those of E. brasiliensis Dana and Acanthonyx scutiformis (Dana). Differences noted between these species pertain to the setation of the carapace, maxillule and second maxilliped. The main morphological features useful for identification are presented together with a summary of features that characterize larvae of majid subfamilies in Brazil. A key for the identification of southwestern Atlantic majid zoeae to the family level is provided.

Bathymetric distribution and recruitment of the spider crab Libinia spinosa H. Milne Edwards 1834 in the Ubatuba and Caraguatatuba regions, northern coast of São Paulo, Brazil (Crustacea, Brachyura, Majoidea, Pisidae)

The objective of this study was to investigate the spatial and temporal distribution of Libinia spinosa H. MILNE EDWARDS 1834 on unconsolidated sublittoral bottoms in two regions off the northern coast of the state of São Paulo, and to analyze the influence of environmental factors on the occurrence of this species and observe the recruitment pattern of its young. Crabs were collected monthly (July 2001 through June 2003) at depths of 5, 10, 15, 20, 25, 30 and 35 In, from a fishing boat equipped with two double-rig nets. Samples of water and sediment were collected for analysis of environmental factors. A total of 2112 spider crabs was obtained (701 juveniles and 1411 adults). The highest abundance was observed at depths of 20 and 25 m, in both regions. These localities were characterized by substrate composed of very fine sand and silt-clay. In regard to the temporal distribution, juveniles and adults predominated in the summer and winter months respectively. From these results, one can infer that the distribution of L. spinosa is related to environmental factors favorable for its life cycle; sediment type is the factor which most strongly determines its presence. © E.
