Effects of Subtle Heterosexism on Gays, Lesbians, and Bisexuals

This study examined heterosexism that is not specifically targeted at LGB individuals, but may be experienced as antigay harassment, and may contribute to the stigma and stress they experience. LGB participants (N= 175, primarily Euro-American college students), read scenarios of heterosexuals saying or assuming things potentially offensive to gay men or lesbian women. For each scenario, they indicated the extent to which they would be offended and less open about their sexuality, and their perceptions of the behaviors as evidence of antigay prejudice. Not only did respondents find the scenarios to be offensive and indicative of prejudice, but perceived offensiveness was associated with a decreased likelihood of coming out. In comparison to gay men, lesbian women and bisexuals found the scenarios more offensive and more indicative of prejudice. Limitations of the current study and directions for future research are outlined

Low burrow occupancy and breeding success of burrowing petrels at Gough Island: a consequence of mouse predation

The predatory behaviour of introduced house mice Mus musculus at Gough Island is known to impact on albatross and petrels, resulting in the Tristan Albatross Diomedea dabbenena and Atlantic Petrel Pterodroma incerta being listed as “Critically Endangered” and “Endangered”, respectively. Although predation has been documented for two burrowing petrels and one albatross species, the impact of house mice on other burrowing petrels on Gough Island is unknown. We report burrow occupancy and breeding success of Atlantic Petrels, Soft-plumaged Petrels Pterodroma mollis, Broadbilled Prions Pachyptila vittata, Grey Petrels Procellaria cinerea and Great Shearwaters Puffinus gravis. With the exception of the Great Shearwater, breeding parameters of burrowing petrels at Gough Island were very poor, with low burrow occupancy (range 4–42%) and low breeding success (0–44%) for four species, and high rates of chick mortality in Atlantic Petrel burrows. Breeding success decreased with mass, suggesting that smaller species are hardest hit, and winter-breeding species had lower breeding success than summer breeders. The results indicate that introduced house mice are having a detrimental impact on a wider range of species than previously recorded and are likely to be causing population declines among most burrowing petrels on Gough Island. The very low values of burrow occupancy recorded for Soft-plumaged Petrels and Broad-billed Prions and greatly reduced abundance of burrowing petrels in comparison to earlier decades indicate that Gough Island’s formerly abundant petrel populations are greatly threatened by the impact of predatory house mice which can only be halted by the eradication of this species from the island
