This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Distribution, movement, behaviour, and habitat selection of a disjunct population of southern flying squirrel, Glaucomys volans, were investigated at three scales: population range, home range, and activity point. The distribution of G. volans in Nova Scotia was delineated by adding 32 new site records to seven historical ones. Site records were obtained from live trapping and public assistance. Using radio telemetry, 53 winter nests were located at five study areas. Tracking revealed that G. volans used on average five nests separated by a mean distance of 300 m over two-month tracking periods. Individuals nested solitarily and aggregated in mixed-sex groups of 2-10 individuals. Glaucomys volans shared home ranges and winter nests with northern flying squirrels, G. sabrinus. Vegetation at G. volans sites was analysed with GIS and ground-truthing. Glaucomys volans in Nova Scotia select species-rich mixedwood forests with red oak and eastern hemlock that have large, mature trees with cavities and standing dead wood.

Book Synopsis Flying Squirrel (Glaucomys Sabrinus and G. Volans) Habitat Use and Ecology in Landscapes Managed with Partial Harvesting Silviculture in Central Ontario by : Gillian Lynn Holloway

Volans) Habitat Use and Ecology in Landscapes Managed with Partial Harvesting Silviculture in Central Ontario written by Gillian Lynn Holloway and published by . This book was released on 2006 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Northern and southern flying squirrels are used as indicator species of sustainable forest management in many regions of North America, including Ontario. However, little is known about flying squirrel ecology or the impacts of partial harvesting on their populations in northeastern North America. I investigated flying squirrel habitat use at multiple spatial scales in both logged and unlogged forests through live-trapping and radio-telemetry. Live-trapping data was used to develop habitat models at the stand and landscape scale for both flying squirrel species, and additionally for red squirrels and eastern chipmunks. I also conducted dietary analyses for all sympatric tree squirrel species, and investigated flying squirrel nest use, home range size, and resource selection within home ranges with radio-telemetry. Northern flying squirrel densities were significantly lower on shelterwood harvested stands compared with unharvested pine stands, which appears to be a consequence of significantly lower densities of large snags, spruce and hardwood trees, and lower understory stem densities on shelterwood cuts. Large hardwood snags were a key nesting substrate for northern flying squirrels. Spruce may be a crucial resource to northern flying squirrels; it is the primary host tree of the mycorrhizal hypogeous fungi which dominated their diet, and northern flying squirrel density and habitat use was associated with spruce tree density at multiple spatial scales. In contrast to northern flying squirrels, southern flying squirrels demonstrated little evidence of a negative response to partial harvesting. This species seems to tolerate lower snag densities in recent selection cuts by nesting in natural and abandoned woodpecker cavities in live trees. Mast availability had a significant influence on southern flying squirrel density at the landscape scale, and on habitat use within home ranges. Southern flying squirrels had a diverse diet in central Ontario (fungi, pollen, seeds, and insects). In order to obtain these varied food resources, this species was active at night in areas with higher tree species diversity than random sites. This study supports past research indicating that northern flying squirrels are associates of mature and old forests (90+ years old); whereas southern flying squirrels demonstrated more flexible habitat use and behaviour.

Book Synopsis Using Energetics and Diet to Predict the Movements of Northern Flying Squirrels (Glaucomys Sabrinus) in the Managed Forests of Southeast Alaska by : Elizabeth A. Flaherty
Download or read book Using Energetics and Diet to Predict the Movements of Northern Flying Squirrels (Glaucomys Sabrinus) in the Managed Forests of Southeast Alaska written by Elizabeth A. Flaherty and published by ProQuest. This book was released on 2008 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, the Tongass Land Management Plan identified the endemic northern flying squirrel (Glaucomys sabrinus griseifrons) as a design species for small old-growth reserves on Prince of Wales Island. The reserve program and harvest plan assumed that flying squirrel populations on the island will exist as a metapopulation in the fragmented landscape. Two life history characteristics, gliding and diet, appear to be closely linked to old-growth habitats. Because timber harvest results in loss of gliding structure and hypogeous fungi, flying squirrels likely will not exist as a functioning metapopulation because of limited dispersal. To assess effects of fragmentation on flying squirrel dispersal, I measured direct costs of transport of quadrupedal locomotion using flow-through respirometry and captive northern flying squirrels. I estimated diet of wild flying squirrels using stable isotope and fecal analyses. Because of potential misinterpretation of linear mixing model results in stable isotope analyses to estimate diet in a fragmented habitat, I modeled habitat effects on resource use and niche. Finally, I measured fine-scale movements of flying squirrels in all three habitat types and estimated perceptual range in the managed stands. I found that cost of quadrupedal locomotion was higher than expected for northern flying squirrels and they may realize over 64% energy savings through gliding. Lichen, conifer seeds, and fungi were main dietary items consumed and assimilated by the wild flying squirrels and old-growth had significantly higher food availability than second-growth stands and clearcuts. Modeling indicated that habitat use could affect isotopic patterns of consumers suggesting that knowledge of habitat use and individual foraging behavior are critical for correct quantification of the ecological niche of flying squirrels and other animals. Perceptual range of flying squirrels was greater in clearcuts than second-growth stands but was significantly shorter than predicted for both habitats. Furthermore, flying squirrels pause more often in clearcuts, leading to higher energetic costs of dispersing through this habitat. Thus, habitat fragmentation through logging may have created barriers to dispersal among forest patches possibly leading to isolation and eventually, localized extinction. With limited dispersal, flying squirrels on Prince of Wales Island will not function as viable metapopulations.

This book was released on 2007 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: We radio-tracked two male and one female Virginia northern flying squirrels (Glaucomys sabrinus fuscus) in the Allegheny Mountains of West Virginia at Snowshoe Mountain Resort, in winter 2003 and Canaan Valley National Wildlife Refuge in winter 2004, respectively, to document winter home range and habitat use in or near ski areas. Male home range size in the winter was larger than that reported for males during summer and fall, whereas the female home range we observed was smaller than those reported for summer and fall. However, winter habitat use was similar to summer and fall habitat use reported in other studies. Virginia northern flying squirrels foraged and denned in both red spruce (Picea rubens)-dominated forests and northern hardwood forests; however, selection of red spruce-dominated forests and open areas was greater than expected based on availability. Use of northern hardwood forest occurred less than expected based on availability. Male squirrels denned near, and routinely crossed, downhill ski slopes and unimproved roads during foraging bouts, whereas the female approached, but did not cross forest edges onto roads or trails.

This book was released on 2006 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia northern flying squirrel (Glaucomys sabrinus fuscus) is an endangered sciurid that occurs in the Allegheny Mountains of Virginia and West Virginia. Despite its status, few of its ecological requirements have been synthesized for landscape-level predictive distributions to facilitate habitat delineation efforts. Using logistic regression, we developed a GIS-based habitat model for the Virginia northern flying squirrel using micro- and macrohabitat relationship data in West Virginia. Important habitat characteristics obtained from radio-collared squirrels included: (1) elevation over 1036 m; (2) northerly aspects; and (3) red spruce (Picea rubens) and mixed northern hardwood-red spruce cover types. A final model retaining elevation and forest cover type showed reasonably high predictive power across a large portion of the Allegheny Mountains in West Virginia.
