This book was released on 1979 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: A population of Spermophilus beecheyi was studied to determine patterns of individual spacing, behavioral interactions among different sex and age classes, and the relationship between aspects of S. beecheyi social structure and sociality to those of other sciurids. Research was conducted on a population of squirrels living in an abandoned rock quarry on Finley National Wildlife Refuge near Corvallis, Oregon. Squirrels were trapped, marked with dye, and observed during March through October, 1977, and March, 1978. The location of each squirrel and the type and location of any encounters were recorded during 325 hours of observation. The types of encounters most often observed were approach/ withdrawal, greeting/investigation, play, displacement, aggression, and the male-initiated paw push. The two major activity peaks occurred in March, corresponding to courtship activity and male defense of breeding territories, and in July, corresponding to the activity of juveniles. The seasonal activity cycle of S. beecheyi had five phases: breeding, pre-emergence of young, litter, pre-hibernation, and hibernation. distinct time of dispersal was determined. The population consisted of approximately twice as many adult females as adult males. Both sexes had overlapping home ranges, but their centers of activity were usually separate from the activity centers of other members of the same sex. Home ranges were retained from year to year by the same squirrel. The most social sciurids are those which exhibit a high frequency of cohesive behaviors, such as greeting and mutual grooming. The S. beecheyi at Finley National Wildlife Refuge tended to be tolerant of other individuals, but did not maintain a high level of cohesive behavior within the population. The social structure of S. beecheyi was intermediate to the more social S. columbianus and the more solitary S. franklinii.

This book was released on 2018 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The California ground squirrel (Otospermophilus beecheyi) is a diurnal rodent native to California. Although abundant throughout their range, their social grouping and dispersal patterns, as well as mating system, are not well described. To date, there are no population genetic studies on this species. I used seven microsatellite markers to determine population genetic structure, test for the presence of a sex-bias in dispersal, examine patterns of relatedness within burrow systems, and describe the mating system within three wildlife refuges located in the Central Valley of California. There was no evidence of genetic differentiation among burrow systems within each refuge, and no biologically significant isolation by distance pattern was observed in any refuge. A weak male-bias in dispersal was detected. Average relatedness within burrow systems was approximately zero for adult males, adult females, and all individuals. There was evidence of both sexes mating with multiple partners within a breeding season. These results suggest that there is a single panmictic population within each refuge in which both males and females are highly dispersive and can disperse over long distances, that California ground squirrels are not remaining in highly social family groups and are aggregating due to some other factor, such as high population density or food resources, and that this species exhibits a polygynandrous mating system. California ground squirrels are the largest agricultural pests in California. Studies of genetic diversity and dispersal patterns such as this could be used to formulate effective management strategies.
