This book was released on 1969 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Red squirrel (Tamiasciurus hudsonicus preblei) population ecology was investigated in a field study conducted between 21 September 1967 and 30 October 1968 near College, Alaska. Population density on the 21 ha study area was one squirrel per 1.1 ha during the spring 1968 and one per 1.2 ha during the fall 1968. Territoriality appears to be somewhat relaxed during the spring, and there are non-territorial squirrels present at that time. Young of the year squirrels can be distinguished from adults, at least through October, according to the degree of closure of the epiphyses of the radius and ulna. Immature males can be distinguished from adults on the basis of testis weight during the fall. Immature squirrels constituted 57.1% of the population sample during the fall 1967 and 51.3% during the fall 1968. Males formed 66.7% of the sample of adults and 64.0% of the sample of immature squirrels. Males were not significantly heavier or larger than females. Mean tail length of immature squirrels exceeded that of adults. Fall molt commences for all red squirrels during late August and September. The spring molt commences for females during March, whereas males do not molt until May. Testes measurements and female reproductive condition indicate that there is a single annual reproductive season, from late February through April. Squirrels breed during their first spring at about 10 to 11 months of age. Estimated mean litter size was 4.20 based on embryo counts and 3.92 based on placental scars. The most frequent litter size was four.

Available in PDF, EPUB and Kindle. Book excerpt: The management of red squirrel populations relies on an extensive knowledge of the ecological, social and economic factors affecting population demography and abundance. This volume contains peer reviewed studies authored by many of the world's leading squirrel experts, and is a collection which will contriobute to the evolution of applied conservation across Europe. Early chapters describe the interaction between red and grey squirrels, and review dietary studies, scatter hoarding strategies, causes of mortality, predation impacts, genetic research, and the impact of habitat fragmentation upon squirrel dispersal. Later case studies present the challenges of managing red and grey squirrels at a local, regional and national scale.
