Space use and dispersal of red squirrels in fragmented habitats

Eurasian red squirrels Sciurus vulgaris in fragmented woodlands had a similar spacing pattern as in large woodlands but home ranges and core-areas were smaller than in large deciduous woodlands, suggesting space use and home range size in habitat fragments are strongly influenced by size and structure of the woodlots.

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.

Space use patterns of mountain hare (Lepus timidus) on the Alps

Populations on the limits of species’ distribution can show different behavioral adaptations to strong ecological pressure than in the central part of the range. We investigated space use patterns of


Examination of seasonal patterns of home-range size, overlap, and distance traveled by male and female Chiricahua fox squirrels from 2002 to 2003 suggests extreme spatial and temporal fluctuations of food experienced by ChirICahuaFox squirrels may result in space use patterns that differ from those of tree squirrels living in forests with a greater abundance of food.

Influences of mating strategy on space use of Arizona gray squirrels

Home ranges were large compared to those of congeners, suggesting an environment with low availability and predictability of resources, and differed by sex and season; females maintained smaller home ranges overlapped more by males than females; overlap by male home ranges increased during the breeding season.

Effects of temporal and spatial variations in food supply on the space and habitat use of red squirrels (Sciurus vulgaris L.)

The results lend support to the hypothesis of Ostfeld (1985) that when food is sparse and patchily distributed, females should develop intrasexual territoriality, concentrating their activity in food-rich patches, while males should be non-territorial and adapt their space use to the distribution of females.

Exclusive core areas and intrasexual territoriality in Eurasian red squirrels (Sciurus vulgaris) revealed by incremental cluster polygon analysis

Female home ranges were more strongly affected by annual fluctuations in food supplies than male ranges, and males probably benefit from using larger home ranges and core areas, which overlap with the ranges of several females, by increasing their probability of successful mating.

Within‐sex density dependence and population dynamics of red squirrels Sciurus vulgaris

Seed crop size positively affected red squirrel densities through increased reproduction, immigration and adult survival of males, but density- dependent reproduction and within-sex density-dependent recruitment of locally born juveniles and dispersing subadults limit the fluctuations in numbers and regulate densities in winter–early spring, as well as in summer.



Home range characteristics and correlates in tree squirrels

Home range patterns of squirrels in the genera Sciurus and Tamiasciurus are reviewed and differential utilization of space within the home range is considered to be a common pattern, although it is rarely explicitly described in tree squirrel studies.

Spacing strategy in stoat Mustela erminea

Experiments indicated scent marking to be important in territorial defence, as were visual and acoustic signals in close contacts in relation to foraging, and after settlement defence was largely performed in connection with foraging.

Dynamics and Regulation of Red Squirrel (Tamiasciurus Hudsonicus) Populations

It is argued that cone production may in this way provide a vehicle through which weather affects squirrel populations was supported by a number of statistically significant negative correlations between Alberta and Saskatchewan fur returns and the preceding year's summer rainfall.


Red squirrels were studied by capture-mark-recapture over a 3-year period in different habitats, and survival was positively correlated with body weight in the second winter of life, independent of body length.

Factors affecting male mating success in red squirrels (Sciurus vulgaris)

The mating behaviour and the factors affecting male mating success in individually marked free-ranging red squirrels (Sciurus vulgaris) were studied over a 4 year period with the aid of

Mating System of a Territorial Tree Squirrel (Tamiasciurus douglasii) in California

The breeding behavior of tree squirrels ( Tamiasciurus douglasii) was studied over a period of 3 years in California, and dominant males had higher mating success than the average subordinate.


Temporal changes and spatial differences in population structure and density of red squirrels were investigated in 3 habitats near Rochester, Alberta, finding survival of squirrels varied seasonally and annually, among habitats and between sex and age cohorts.

Adaptive significance of sexual dimorphism in weasels

Field data showed no long-lasting pair bonds between males and females; movements and behaviour of males during the breeding season indicated a polygynous or promiscuous mating system with the females alone rearing the young.

Limiting Resources and Territoriality in Microtine Rodents

A set of hypotheses to predict under what conditions females and males should defend territories are proposed and the relation between diet and female territoriality holds up well, with the caution that diet and behavior are seldom analyzed in the same population at the same time.
