Yarning as a method for building sexual wellbeing among urban Aboriginal young people in Australia.

This paper describes the strategies used by Aboriginal young people to build positive relationships and sexual wellbeing. It does so to counter the risk-focussed narratives present in much existing research and to showcase the resourcefulness of Aboriginal young people. We used peer-interview methods to collect qualitative data from 52 Aboriginal young people living in western Sydney, Australia. Participants reported a strong desire to stay safe and healthy in their sexual relationships and to achieve this they relied heavily on oral communication and yarning strategies. Participants viewed communication as a way to gain or give advice (about bodies, infections, pregnancy, relationships); to assess the acceptability and safety of potential partners; to negotiate consent with partners; to build positive relationships; and to get themselves out of unhealthy relationships. Participants also discussed 'self-talk' as a strategy for building sexual wellbeing, referring to narratives of self-respect and pride in culture as important in establishing Aboriginal young people's positive views of self and as deserving of respectful and safe sexual relationships. These findings suggest that future programmes and interventions based on yarning could be well-regarded, given it is a cultural form of pedagogy and a strategy Aboriginal young people already use to build positive relationships and identities.

Aboriginal young people's perspectives and experiences of accessing sexual health services and sex education in Australia: A qualitative study.

Aboriginal and Torres Strait Islander (Aboriginal) young people seek information and access health services for their sexual health needs. This study examined Aboriginal young people's perspectives on sexual health services and sex education in Australia. Overall, 51 Aboriginal people aged 16-26 years were interviewed by peer researchers in Sydney, Australia in 2019-2020. The findings suggest that the internet was used to assess information quickly and confidentially, but Aboriginal young people questioned its reliability and accuracy. Family, Elders and peers were seen as sources of advice because they had real-life experience and highlighted intergenerational learning that occurs in Aboriginal communities. School-based sex education programmes had mixed reviews, with a preference for programmes delivered by external specialists providing anonymity, clear and accurate information about sex and relationships and positive approaches to sex education, including how to gain consent before sex. There was a need identified for school-based programmes to better consider the needs of Aboriginal young people, including those who identified as LGBTQI + . Aboriginal Medical Services were highly valued for providing culturally safe access to services, while sexual health clinics were valued for providing specialised confidential clinical services with low levels of judgement.

Foraging scent marks of bumblebees: footprint cues rather than pheromone signals.

In their natural habitat foraging bumblebees refuse to land on and probe flowers that have been recently visited (and depleted) by themselves, conspecifics or other bees, which increases their overall rate of nectar intake. This avoidance is often based on recognition of scent marks deposited by previous visitors. While the term 'scent mark' implies active labelling, it is an open question whether the repellent chemicals are pheromones actively and specifically released during flower visits, or mere footprints deposited unspecifically wherever bees walk. To distinguish between the two possibilities, we presented worker bumblebees (Bombus terrestris) with three types of feeders in a laboratory experiment: unvisited control feeders, passive feeders with a corolla that the bee had walked over on its way from the nest (with unspecific footprints), and active feeders, which the bee had just visited and depleted, but which were immediately refilled with sugar-water (potentially with specific scent marks). Bumblebees rejected both active and passive feeders more frequently than unvisited controls. The rate of rejection of passive feeders was only slightly lower than that of active feeders, and this difference vanished completely when passive corollas were walked over repeatedly on the way from the nest. Thus, mere footprints were sufficient to emulate the repellent effect of an actual feeder visit. In confirmation, glass slides on which bumblebees had walked on near the nest entrance accumulated hydrocarbons (alkanes and alkenes, C23 to C31), which had previously been shown to elicit repellency in flower choice experiments. We conclude that repellent scent marks are mere footprints, which foraging bees avoid when they encounter them in a foraging context.
