Data on seasonal ranges of 93 radio-collared adult brown bears (Ursus arctos) were used to test hypotheses explaining variation in range size in relation to male and female reproductive strategies. Both males and oestrous females used large ranges in the mating season, but decreased their ranges after the mating season. These results suggested that both sexes in this species roam to mate, because the results could not be explained by a seasonal change in food availability nor by increased…

Seasonal changes in home ranges of Abert's squirrels: impact of mating season

Home ranges of introduced Abert's squirrels in mixed- conifer forests of Arizona during non-mating and mating seasons are compared to show how changes in resource use and competition for space during the mating season may affect home ranges.

Sexual dimorphism and the mating ecology of polar bears (Ursus maritimus) at Svalbard

The wide range of male size in male-female pairs and the age-related signs of injury suggest that male polar bears engage in both scramble competition and contest competition for access to breeding females.

Effect of sex and female reproductive status on seasonal home range size and stability in

It is hypothesized that reproductive females monopolize the richest food patches at the expense of non-reproductive females, which are younger and assumed to be subordinate and/or less experienced, and may be an important factor for female reproductive success.

Effect of sex and female reproductive status on seasonal home range size and stability in rural red foxes (Vulpes vulpes)

It is hypothesized that reproductive females monopolize the richest food patches at the expense of non-reproductive females, which are younger and assumed to be subordinate and/or less experienced, and home range size correlated to food richness may be an important factor for female reproductive success.

Home Range Size Variation in Female Arctic Grizzly Bears Relative to Reproductive Status and Resource Availability

It was found that the reproductive status of female grizzlies affected home range size but individually-based spatial availability of highly selected cover in spring and early summer was a stronger correlate.

Courtship of brown bears Ursus arctos in northern Spain: phenology, weather, habitat and durable mating areas

Abstract During 1988–2004 we made 297 non-systematic direct observations of free-ranging brown bears Ursus arctos in the Cantabrian Range of Spain, one of the southernmost and most endangered

Females roam while males patrol: divergence in breeding season movements of pack-ice polar bears (Ursus maritimus)

Movement data collected from adult male polar bears with novel ear-attached transmitters in two separate pack ice subpopulations over five breeding seasons suggest a possible mechanism for explaining the smaller breeding range sizes of some solitary male carnivores compared to females.

Sexual and seasonal differences of space use in Alpine chamois

Sexual and seasonal differences in space use of northern chamois may have been linked to energetic and mating requirements, with females selecting high-quality feeding areas because of their energy demands during gestation and lactation.

Geographic variation in size, growth, and sexual dimorphism of Alaska brown bears, Ursus arctos

A strong hyperallometric relationship in sexual size dimorphism (SSD) where SSD increased with asymptotic size is found, which supports sexual selection as the driving mechanism of SSD in brown bears.

Home ranges in adult Scandinavian brown bears (Ursus arctos): effect of mass, sex, reproductive category, population density and habitat type

Home-range size in both males and females was inversely related to population density along a density gradient that was not linked to food availability, contradicting the hypothesis that females use the minimum areas that sustain their energy requirements.

Reproductive Status and Movement of Adult Female Alligators

Adult female alligators had larger home ranges, greater movement, and spent less time at or near their den sites during the spring breeding season than any other season of the year.

Study of grizzly bear populations in Kananaskis and Selkirk Mountains of Idaho finds results are inconsistent with the no avoidance and food hypotheses but consistent with the sex hypothesis of sexual segregation.

Geographic expansion of an increasing brown bear population: evidence for presaturation dispersal

The results strongly suggest that presaturation dispersal, i.e. dispersal occurring before the carrying capacity of the habitat has been reached, is occurring in this increasing population of brown bears in Sweden, and might be more common in increasing populations of large mammals than was previously thought.

Despite overall similarities in the mating system of this species and that of other macropods, male mating success may be less skewed in bridled nailtail wallabies than in other species, although paternity analysis of free-ranging populations of other species is required to confirm this conclusion.

Habitat use and ecological correlates of home range size in a small cervid : the roe deer

The analyses of habitat selection inside each home range showed that the forest types, characterized by high densities of food and low visibility, were preferred, suggesting that habitat use is allocated in proportion to either food or cover or both.

The major difference between the Swedish and Norwegian areas was the large consumption of sheep in Norway, which provided protein and lipids, and was associated with a relatively reduced consumption of ants and forbs in summer and berries in the autumn.
