Book Description
"In this rapidly developing world, the relationship between humans and wildlife is becoming more strained. Despite the challenges, some animals respond better than others to the additional pressures present in urban environments, and squirrels are a prime example (McKinney, 2002). Several studies have focused on the distribution and abundance of tree squirrels in urban landscapes, but more information is needed to understand the connections between anthropogenic factors and population density (Shochat et al., 2006). Previous research that examined leaf nest densities within residential neighborhoods found a positive correlation between property value and nest density (Salsbury et al., unpublished data). The biological explanation of this relationship was unclear, so a follow-up study was necessary to further investigate this connection. The potential anthropogenic effects on Eastern fox squirrel (Sciurus niger) distribution and abundance in urban residential areas was investigated using a combination of leaf nest surveys, observations of squirrel activity, and a citizen scientist questionnaire. The results indicated that the reported relationship between leaf nest density and property value was likely a correlation without causation. There were also inconsistencies in the relationship between squirrel activity and leaf nest density, and the squirrels appeared to be changing their nest locations relatively frequently. Therefore, there are likely other anthropogenic and environmental factors that have a stronger influence on squirrel activity and leaf nest density"--Provided by author.

Book Description
Home ranges, nest use, and primary food resources of Sherman's fox squirrel (Sciurus niger shermani) were studied on the University of Florida's Katharine Ordway Research Preserve in Putnam County, Florida. Sherman's fox squirrel is a distinctive subpopulation with a small geographic range which is declining in Florida due to habitat loss. To understand production of its primary food resources, seed production of longleaf pines (Pinus palustris) and turkey oaks (Quercus laevis) was monitored for two years on contrasting sites of high (ecotone) and low (upland) productivity. Mast production varied by site, tree, year, and tree size. Production was higher in the ecotone, significantly so in turkey oaks. In the second year, the turkey oak acorn crop failed entirely. Patchiness of these primary food resources likely explains the very large home range size of this animal. Six fox squirrels were radio-collared and tracked for varying lengths of time over a one-year period. Home range size was significantly greater in males than in females. Home range size, position, and intensity of use were probably affected not only by sex, but also by resource abundance, reproductive season, and weather factors. Squirrels used a calculated average of 30 nests/year, mostly "leaf-nests" as opposed to tree cavities. More time was spent in the nest during cold and very wet weather, indicating decreased activity during these times. Squirrel density was estimated to be roughly 12/km Nest counts appeared to provide a reliable estimate of this density on the squirrel study area and are recommended for testing in other areas of the squirrels' range. Habitat management is of primary importance to the survival of Sherman's fox squirrel. Preservation and maintenance of natural, mature longleaf pine forests is needed for successful management.
