The relative growth and sexual maturity of the freshwater crab Dilocarcinus pagei (Brachyura, Trichodactylidae) in the northwestern region of the state of São Paulo

The aim of the present study was to determine the size at sexual maturity in the freshwater crab Dilocarcinus pagei Stimpson, 1861, from a population located in Mendonça, state of São Paulo, Brazil. The crabs were sampled monthly (July 2005 to June 2007), at Barra Mansa reservoir. The specimens were captured manually or in sieves passed through the aquatic vegetation. The crabs were captured and separated by sex based on morphology of the pleon and on the number of pleopods. The following dimensions were measured: carapace width (CW); carapace length (CL); propodus length (PL); and abdomen width (AW). The morphological analysis of the gonads was used to identify and categorize individuals according to their stage of development. The morphological maturity was estimated based on the analysis of relative growth based on the allometric equation y = ax b. The gonadal maturity was based on the morphology of the gonads by the method CW50 which indicates the size at which 50% of the individuals in the population showed gonads morphologically mature to reproduction. The biometric relationships that best demonstrated the different patterns of growth for the juvenile and adult stages were CW vs. PL for males and CW vs. AW for females (p<0.001). Based on these relationships, the estimated value to morphological sexual maturity was 21.5 mm (CW) in males and 19.7 mm (CW) in females. The determination of the size at sexual maturity and the adjustment of the data based on the logistic curve (CW50) resulted in a size of 38.2 mm for males and 39.4 mm for females (CW). Based on the data obtained for sexual maturity for D. pagei, we can estimate a minimum size for capture of 40 mm (CW). This minimum size allows at least half of the population to reproduce and retains the juveniles and a portion of the adults in the population.

JUVENILE DEVELOPMENT OF DILOCARCINUS PAGEI STIMPSON, 1861 (BRACHYURA, TRICHODACTYLIDAE) REARED IN THE LABORATORY, WITH EMPHASIS ON SETAE MORPHOLOGY

The juvenile development of the freshwater crab Dilocarcinus pagei Stimpson, 1861 was studied under laboratory conditions, focusing on setae morphology. The ovigerous females were collected manually associated with water hyacinth at the Municipal Dam of Sao Jose do Rio Preto (Sao Paulo, Brazil). The specimens were raised in the laboratory under constant aeration, photoperiod (12: 12 h) and temperature (27 +/- 1 degrees C). Twelve juvenile stages were obtained with descriptions of the main morphological characters that allow their identification are presented. Fourteen types of setae were discovered: dentate, denticulate, serrulate, papposerrate, cuspidate, plumose, plumodenticulate, plumoserrulate, simple, pappose, brush, curved, nail and setules. The greatest diversity of setae was found on the mouth appendages, especially the maxillule. The gill ontogeny and sexual dimorphism becomes apparent from the second juvenile stage onwards. At the third juvenile stage, the carapace begins to exhibit a wider shape, becoming similar to that of the adults.

Obesogenic environment by excess of dietary fats in different phases of development reduces spermatic efficiency of wistar rats at adulthood: correlations with metabolic status

This study compares the impact of obesogenic environment (OE) in six different periods of development on sperm parameters and the testicular structure of adult rats and their correlations with sex steroid and metabolic scenario. Wistar rats were exposed to OE during gestation (O1), during gestation/lactation (O2), from weaning to adulthood (O3), from lactation to adulthood (O4), from gestation to sexual maturity (O5), and after sexual maturation (O6). OE was induced by a 20% fat diet, and control groups were fed a balanced diet (4% fat). Serum leptin levels and adiposity index indicate that all groups were obese, except for O1. Three progressive levels of impaired metabolic status were observed: O1 presented insulin resistance, O2 were insulin resistant and obese, and groups O3, O4, and O5 were insulin resistant, obese, and diabetic. These three levels of metabolic damage were proportional to the increase of leptin and decreased circulating testosterone. The impairment in the daily sperm production (DSP) paralleled these three levels of metabolic and hormonal damage being marginal in O1, increasing in O2, and being higher in groups O3, O4, O5, and O6. None of the OE periods affected the sperm transit time in the epididymis, and the lower sperm reserves were caused mainly by impaired DSP. In conclusion, OE during sexual maturation markedly reduces the DSP at adulthood in the rat. A severe reduction in the DSP also occurs in OE exposure during gestation/lactation but not in gestation, indicating that breast-feeding is a critical period for spermatogenic impairment under obesogenic conditions.

Sexualidade e orientação sexual na escola em foco: algumas reflexões sobre a formação de professores

This article discusses the training of teachers to work with sexuality issues in regular school environment after the creation of the National Curriculum (PCNs) in 1997. The authors note that over a decade there have been no official regular and systematic initiatives or incentives to provide teachers with sex education disciplines at undergraduate level in Pedagogy, Teachers’ Training, Continuing Education or Initial Training courses, with rare exceptions. Generally the work with sexuality and sex education carry with it some coadjutors such as ignorance, prejudice, taboo and discrimination. In this way, if teachers are prepared to approach the field, they will experience a significant gain in performance and in the psycho-social development of their students, as well as work in a process of citizenship education.

O preconceito como obstáculo à educação sexual: reflexões a partir de uma perspectiva ética

This paper developed a reflection about problems related to the establishment of ethical principles that guide the sexual education aiming at emancipation. Our theoretical framework is the Critical Theory of Society, in particular texts by T. W. Adorno on training, prejudice and education. It is understood that numerous difficulties are related to the achievement of an emancipatory education, and such difficulties are even greater when it comes to sex education since it is an issue that still raises irrational fears on educators, and is absent from the training they received. Following Adorno, it is understood that the current formation favors the development of subjects inclined to prejudice, and that an emancipatory sexual education involves a critique to the conditions under which such formation occurs and, at the same time, a continuous reflection about the relations between the desires and the social possibilities of their realization.

Projeto de intervenção em educação sexual com educadoras e alunos de uma pré-escola

Childhood sexuality is a polemic theme among pre-school educators. This text describes an extension project that aimed to observe the manifestation of children’s sexuality in a pre-school and to intervene by offering a space for dialogue, reflection and better understanding about childhood sexuality. The participants were seven teachers and whole group of children from a selected pre-school. It was observed (1) among the educators: the different games applied according to gender; how tolerant the teachers were regarding to boys bad behavior; vigilance against the homosexuality and constant motivation to female vanity and beauty. (2) Among the children: sexist stereotypes; manifestations of racism and prejudice; curiosity and interest about the body and sexuality and the use of insulting words concerning body beauty. The teacher education discussed theoretical and practical issues about the development of the sexuality in the childhood and the sexual education of their students. The project observed that a sexual education project can be put into practice in a pedagogical and ethical way in a pre-school environment.
