At what age can females consent to sexual activity? A survey of jury-eligible Australians

One suggested reason for the low conviction rates of alleged child sexual abuse offenders relates to the attitudes and beliefs the public hold about such victims; sexual interactions starting at an earlier age; and because the oversexualisation of children and teenagers portrayed in the media may have affected perceptions as to when females are capable ofgiving consent to sexual interactions. A sample of 580 jury-eligible participants completed six implicit questions via an online survey regarding females' capacity to consent. While participants had similar perceptions in response to the type of question asked, there were some differences due to respondent group. When significant differences were observed, women had significantly lower estimates of the age at which female adolescents can make informed decisions about sexual activity than men, as did respondents who had children and were older. Working with children had little impact. The legal implications of these findings are discussed.

Young people, pleasure, and the normalization of pornography: sexual health and well-being in a time of proliferation?

It has been argued that pornography is the most prominent sex educator for young people today (Flood, M. (2010). Young men using pornography. In E. Boyle (Ed.), Everyday Pornography (pp. 164–178). Oxford: Routledge). Research indicates that first exposure to pornography can be as young as 11 years of age. There is evidence that exposure to pornography is shaping young people’s sexual expectations and practices (H€aggstro ̈ m-Nordin et al. 2005). Many young people are learning what sex looks like from what they – or their partner or peers – observe in pornography. Significantly,pornography is normalizing sex acts that most women do not enjoy and may experience as degrading, painful, or violating. This raises serious implications for young people’s capacity to develop a sexuality that incorporates mutual pleasure, respect, and negotiation of free and full consent.While the results are complex and nuanced, research into the effects of pornography consumption provides reliable evidence that exposure to pornography increases aggressive attitudes and behavior towards women for some viewers (Malamuth et al. Annual Review of Sex Research 11, 26–91, 2000). Pornography consumption also has been found to be associated with sexual health risk taking and can impact negatively on body image and sense of self (Dean, L. (2007). Young Men, Pornography and Sexual Health Promotion, MA Research, Brighton University, Brighton, in possession of the author), and as such is a serious health and well-being issue, particularly for young women.This chapter explores preservice teachers’ reactions to pornography education using two examples from teaching of an elective Teaching Sexuality in the Middle Years, in 2011. These examples explore the complex emotions such teaching can generate and the challenges faced by preservice teachers when they are encouraged to confront the gendered and violent consequences of the normalization of pornography in a coeducational setting.

Early-life sexual segregation: ontogeny of isotopic niche differentiation in the Antarctic fur seal

Investigating the ontogeny of niche differentiation enables to determine at which life-stages sexual segregation arises, providing insights into the main factors driving resource partitioning. We investigated the ontogeny of foraging ecology in Antarctic fur seals (Arctocephalus gazella), a highly dimorphic species with contrasting breeding strategies between sexes. Sequential δ(13)C and δ(15)N values of whiskers provided a longitudinal proxy of the foraging niche throughout the whole life of seals, from weaning, when size dimorphism is minimal to the age of 5. Females exhibited an early-life ontogenetic shift, from a total segregation during their first year at-sea, to a similar isotopic niche as breeding females as early as age 2. In contrast, males showed a progressive change in isotopic niche throughout their development such that 5-year-old males did not share the same niche as territorial bulls. Interestingly, males and females segregated straight after weaning with males appearing to feed in more southerly habitats than females. This spatial segregation was of similar amplitude as observed in breeding adults and was maintained throughout development. Such early-life niche differentiation is an unusual pattern and indicates size dimorphism and breeding constraints do not directly drive sexual segregation contrary to what has been assumed in otariid seals.

Sexual segregation in habitat use is smaller than expected in a highly dimorphic marine predator, the southern sea lion

Sexual segregation in habitat use is widely reported in many taxa and can profoundly influence the distribution and behaviour of animals. However, our knowledge of the mechanisms driving sexual segregation is still in its infancy (particularly in marine taxa) and the influence of extrinsic factors in mediating the expression of sex differences in foraging behaviour is underdeveloped. Here, we combine data from biologging tags, with stable isotope analysis of vibrissae, to assess sexual segregation in southern sea lions (SSL) (Otaria flavescens) breeding at the Falkland Islands in the South Atlantic. We found evidence to support segregation, most notably in δ13C and δ15N values. However, in spite of extreme sexual size dimorphism and differing constraints related to female-only parental care, adult male and adult female SSL overlapped considerably in isotopic niches and foraging area, and shared similar foraging trip characteristics (such as distance and duration). This is in contrast to SSL breeding in Argentina, where prior studies report sexual differences in foraging locations and foraging trip characteristics. We posit that sexual segregation in SSL is influenced by habitat availability (defined here as the width of the Patagonian Shelf) and individual foraging preferences, rather than commonly invoked individual-based limiting factors per se.
