tamiasciurus hudsonicus การใช้

• For example, the North American red squirrel ( " Tamiasciurus hudsonicus " ) usually has one large active midden in each territory with perhaps an inactive or auxiliary midden.
• The main proximate cause of mortality was predation by small mammals, including red squirrels ( " Tamiasciurus hudsonicus " ) and Arctic ground squirrels ( " Spermophilus parryii " ).
• Other small mammals that commonly are found on the refuge include eastern chipmunk ( " Tamias striatus " ), American red squirrel ( " Tamiasciurus hudsonicus " ), and eastern grey squirrel ( " Sciurus carolinensis " ).
• The North American Red Squirrel ( " Tamiasciurus hudsonicus " ) has experienced an increase in average temperature over this last decade of almost 2 癈 . This increase in temperature has caused an increase in abundance of white spruce cones, the main food source for winter and spring reproduction.
• Corms and bulbs are important when available as they are one of the greater sources of protein in plant life as are Whitebark pine nut ( " Pinus albicaulis " ), which is attained perhaps a majority of the time by raiding the once abundant caches of American red squirrels ( " Tamiasciurus hudsonicus " ) rather than direct foraging.
• Particularly the American red squirrel ( " Tamiasciurus hudsonicus " ) is significant, being the primary prey in studies from Minnesota, South Dakota, Wyoming and Montana ( in each comprising more than 30 % of the diet and present in more than half of known pellets ) but also reported everywhere in their foods from the eastern United States to Alaska and Arizona.
