Factors Associated With Sexual Coercion in a Representative Sample of Men in Australian Prisons

Very little research has focused on men or prisoners as victims of sexual violence. This study provides the first population-based analysis of factors associated with sexual coercion of men in Australian prisons, and the first to use a computer-assisted telephone interview to collect this information in a prison setting. A random sample of men in New South Wales and Queensland prisons were surveyed using computer-assisted telephone interviewing. We asked participants about sexual coercion, defined as being forced or frightened into doing something sexually that was unwanted while in prison. Associations between sexual coercion in prison and sociodemographics, sexual coercion history outside of prison, and prison-related factors were examined. Logistic regression was used to estimate adjusted odds ratios in examining factors associated with sexual coercion in prisons. Of 2626 eligible men, 2000 participated. Participants identifying as non-heterosexual and those with a history of sexual coercion outside prison were found to be most at risk. Those in prison for the first time and those who had spent more than 5 years in prison ever were also more likely to report sexual coercion. Although prison policies and improving prison officer training may help address immediate safety and health concerns of those at risk, given the sensitivity of the issue and likely under-reporting to correctional staff, community-based organizations and prisoner peer-based groups arguably have a role too in providing both preventive and trauma-focused support

Data from: Demographic history influences spatial patterns of genetic diversity in recently expanded coyote (Canis latrans) populations

Human-mediated range expansions have increased in recent decades and represent unique opportunities to evaluate genetic outcomes of establishing peripheral populations across broad expansion fronts. Over the past century, coyotes (Canis latrans) have undergone a pervasive range expansion and now inhabit every state in the continental United States. Coyote expansion into eastern North America was facilitated by anthropogenic landscape changes and followed two broad expansion fronts. The northern expansion extended through the Great Lakes region and southern Canada, where hybridization with remnant wolf populations was common. The southern and more recent expansion front occurred approximately 40 years later and across territory where gray wolves have been historically absent and remnant red wolves were extirpated in the 1970s. We conducted a genetic survey at 10 microsatellite loci of 482 coyotes originating from 11 eastern U.S. states to address how divergent demographic histories influence geographic patterns of genetic diversity. We found that population structure corresponded to a north-south divide, which is consistent with the two known expansion routes. Additionally, we observed extremely high genetic diversity, which is atypical of recently expanded populations and is likely the result of multiple complex demographic processes, in addition to hybridization with other Canis species. Finally, we considered the transition of allele frequencies across geographic space and suggest the mid-Atlantic states of North Carolina and Virginia as an emerging contact zone between these two distinct coyote expansion fronts
