Survivorship of a nonharvested raccoon population in south Texas
Article Abstract:
There is a need to examine the survival of raccoons which are not exposed to hunting in order to assess the impact of hunting. A study carried out in south Texas has showed low juvenile survivorship for nestlings, though survival rates improved as the young raccoons became old enough to travel with their mothers. Surival rates may be affected by den structures, and whether they give protection against predators. Adult males and females have similar rates of survival where there is no harvest. Harvesting could have effects of social behavior and other aspects of raccoons.

Behavioural aspects of the raccoon mating system: determinants of courtship success
Article Abstract:
Raccoons were observed in Texas in 1990 and 1991, and one male was dominant in each group, consorting with more females for longer that other males. Females may have carried out more multiple matings than observed. The behavioral data shows a continnuum from polygyny to promiscuity for the raccoon mating system. The spatial dispersion of females affects the males' ability to achieve polygyny. The time of females' oestrus cycles, and the spatial distribution of females affect the success of males and the mating susyem as a whole.

Resource distribution, female home range dispersion and male spatial interactions: group structure in a solitary carnivore
Article Abstract:
Female home range and male spatial interactions were monitored using 41 radio-collared male and 33 radio-collared female raccoons, Procyon lotor, in Welder Wildlife Refuge, TX. During times of water limitation, female home ranges were found to be close to one another but were more randomly distributed when this resource becomes less limiting. While resource availability defines the home ranges of females, the territory selection among males depends on female distribution.
