Effects of removal of red squirrels, Tamiasciurus
hudonicus, and eastern chipmunks, 'lamias striatus, on nest predation in a northern hardwood forest: an artificial nest experiment.
Slash piles do not replace natural den features such as logs, snags, rock crevices, and squirrel (Tamiasciurus
spp.) middens (see Ruggiero and others 1998), but where logging occurs in pine forests, quantities of slash equal to or greater than those created during operational scale salvage logging may be a practical, important habitat management approach for maintaining ground-level structure and providing prey reservoirs for marten in south-central Oregon (see Sullivan and others 2012; Wilk and Raphael 2017).
Cutaneous and systemic poxviral disease in red (Tamiasciurus
hudsonicus) and gray (Sciurus carolinensis) squirrels.
2012) that were not recorded during the present or previous research in this location include red squirrel (Tamiasciurus
hudsonicus), northern flying squirrel (Glaucomys sabrinus), southern flying squirrel (Glaucomys volans), bobcat, red fox, black bear, North American river otter (Lontra canadensis), and American mink (Neovison vison) and the introduced species house mouse (Mus musculus), brown/Norway rat (Rattus norvegicus), and domesticated dog.
cinereus (n = 5), deer mice Peromyscus maniculatus (n = 10), red squirrels Tamiasciurus
hudsonicus (n = 12), ruffed grouse Bonasa umbellus (n = 7), white-tailed deer Odocoileus virginianus (n = 18), woodpeckers (n = 4), acorns Quercus sp.
We suggest that the eastern gray squirrel might become more damaging to the two native diurnal species of tree squirrels in California, Sciurus griseus and Tamiasciurus
douglasii, than the introduced eastern fox squirrel (Sciurus niger).
(187) About this time, the United States Fish and Wildlife Service listed the Mount Graham red squirrel (Tamiasciurus
hudsonicus grahamensis) as endangered, which led the Forest Service to further adjust its preferred alternative, and the consortium to object as it viewed this alternative as not allowing for a viable project to proceed.
Coccidia (Apicomplexa: Eimeriidae) from sciurid rodents (Eutamias, Sciurus, Tamiasciurus
spp.) from the western United States and northern Mexico with descriptions of two new species.
Some taxa which have been studied include viverrids (Atilax, Bdeogal, Civettictis, Genetta, Helogale, Herpestes, Ichneumia, Mungos, and Nandinia) from eastern Africa (Taylor 1971), water voles (Arvicola terrestris monticola) from Europe (Ventura and Gotzens 2005), squirrels (Glaucomys sabrinus, Arborimus logicaudus, Tamiasciurus
douglasii, Sciurus griseus, and Tamias spp.) and woodrats (Neotoma spp.) from Oregon (Forsman and Otto 2006), and Virginia opossums (Didelphis virginiana) from Georgia (Mead and Patterson 2009).
Of the total animals captured, 23 were non-mouse species, including 10 Eastern Chipmunks (Tamias striatus), nine Northern Short-tailed Shrews (Blarina brevicauda), and four Red Squirrels (Tamiasciurus
Poxvirus infection in an American red squirrel (Tamiasciurus
hudsonicus) from Northwestern Canada.
In contrast, young red squirrels Tamiasciurus
hudsonicus had higher survival rates at the edge than at the interior of a forest probably due to differences in food availability between habitats (ANDERSON & BOUTIN, 2002).
