To determine factors influencing Hispanic women's HIV-related communication and condom use with their primary male partner, 189 Dominican, Puerto Rican, and Mexican women were interviewed regarding sexual behaviour and condom use, relationship characteristics, perceived risk for HIV, and HIV-related communication with the primary male partner. Level of HIV-related communication with the primary male partner was associated with the woman's perceived risk for HIV and her rating of the openness with which she could communicate with her primary partner. Mexican women were less likely than Puerto Rican or Dominican women and women with multiple partners were less likely than those with one partner to communicate about HIV-related issues with their primary partner. Women reporting more condom use with their primary partner were younger, had discussed HIV-related issues more with the primary partner, and were less likely to expect negative reactions to requests for condom use than those reporting less condom use. These results suggest that prevention programmes that increase both general and HIV-specific communication between members of a couple may facilitate safer sex practices by the couple. Prevention programmes that encourage women to insist on condom use should consider the woman's expectations about her partner's reaction as a potential barrier to the initiation of safer sex practices.

This report describes the foraging pattern of the Florida harvester ant Pogonomyrmex badius in a high-density population of colonies. The foraging pattern has both promoted and been influenced by the colony distribution. Pogonomyrmex badius forages from short trails which extend into a surrounding foraging range. Direction of foraging trails is influenced by the location of a colony's near neighbors. Seasonal nest relocations always occur along a foraging trail, usually the main trail. Foraging ranges are not actively defended, but are used almost exclusively by foragers from a single colony. Foraging ranges will be extended into an area abandoned by neighboring foragers, indicating that forager presence may define each colony's range. Colony distribution has remained essentially the same for several years, despite seasonal nest relocations and addition of new colonies. Establishment of trails and exclusive foraging ranges by each colony minimizes encounters with neighboring foragers and guarantees access to available resources; this pattern also promotes maintenance of the existing colony distribution and partitioning of resources.
