Most plant species are hermaphrodites, with both male and female functions performed by the same individuals. However, separate sexes (dioecy) have evolved on numerous independent occasions, probably either in response to selection for inbreeding avoidance, or because it pays individuals to specialize in one gender or the other. Although the evolution of dioecy from hermaphroditism tends to be thought of as a one-way path, dioecy has broken down to yield hermaphroditic populations on several occasions. One such case is found in the mainly dioecious genus Mercurialis (Euphorbiaceae). In the species complex M. annua, diploids are dioecious, but polyploid populations are variously monoecious or androdioecious (where males co-exist with functional hermaphrodites). This species complex offers rich material for addressing questions concerning the evolution and ecology of combined versus separate sexes, the evolution of secondary sexual dimorphism, which likely contributes to the stability of dioecy in the genus, and the evolution and genetics of sex determination and sex chromosomes. The species also offers itself as a valuable teaching tool for addressing topics ranging from sex-ratio selection to inter-sexual competition.

The main purpose of this research project is to analyse the major female figures in Wilkie Collins' work of fiction The Law and the Lady, in relation to the times in which the novel was produced and the situation of women in the Victorian era. After taking into account the major events of the life of the author, as well as the sociohistorical conditions of the Victorian period, I try to reach conclusions about whether the author challenges gender-role expectations, presenting the readers with a new form of femininity, of if, on the contrary, he preserves and maintains a conservative, traditional perspective of femininity and female conventions proper to the established parameters of the times in which he lived.

ABSTRACT: BACKGROUND: The relationship between body mass index (BMI) and socioeconomic status (SES) tends to change over time and across populations. In this study, we examined, separately in men and women, whether the association between BMI and SES changed over successive birth cohorts in the Seychelles (Indian Ocean, African region). METHODS: We used data from all participants in three surveys conducted in 1989, 1994 and 2004 in independent random samples of the population aged 25-64 years in the Seychelles (N= 3'403). We used linear regression to model mean BMI according to age, cohort, SES and smoking status, allowing for a quadratic term for age to account for a curvilinear relation between BMI and age and interactions between SES and age and between SES and cohorts to test whether the relation between SES and BMI changed across subsequent cohorts. All analyses were performed separately in men and women. RESULTS: BMI increased with age in all birth cohorts. BMI was lower in men of low SES than high SES but was higher in women of low SES than high SES. In all SES categories, BMI increased over successive cohorts (1.24 kg/m2 in men and 1.51 kg/m2 for a 10-year increase in birth cohorts, p <0.001). The difference in BMI between men or women of high vs. low SES did not change significantly across successive cohorts (the interaction between SES and year of birth of cohort was statistically not significant). Smoking was associated with lower BMI in men and women (respectively -1.55 kg/m2 and 2.46 kg/m2, p <0.001). CONCLUSIONS: Although large differences exist between men and women, social patterning of BMI did not change significantly over successive cohorts in this population of a middle-income country in the African region.
