Lodgepole chipmunk
The Lodgepole chipmunk (''Tamias speciosus'') is a species of rodent in the family Sciuridae. It is found in the U.S. state of California at elevations from .〔 The Lodgepole Chipmunk has a variety of common names including: Tahoe Chipmunk, Sequoia Chipmunk, Mt. Pinos Chipmunk, and San Bernardino Chipmunk.〔(American Mammals: Tamiasspeciosus." North American Mammals: Tamiasspeciosus. Smithonian Institute, n.d. Web. 5 Dec. 2014 ).〕
==Sexual Dimorphism & Phenotype Characteristics==
Sexual dimorphism can be witnessed in the Lodgepole Chipmunk as females are known to be larger in size than males. Female Lodgepole Chipmunks have an average body weight of 55-69 grams whereas males on average are 50-60 grams in total weight.〔 Along with weight, females can be observed having a body length ranging from 197–229 mm (7 3/4 - 9 inches), while males typically exhibit an average body length of 200–222 mm (7.8 - 8.7 inches).〔 Body patterns remain consistent in both sexes as they exhibit characteristic white dorsal and facial stripes, where the central dorsal stripes are known to be less prominent and closer to yellow-white than that of the lateral white stripes. In comparison to other close relatives, this species can be identified by examination of the darker and more broad facial stripes. Other notable body patterns include dark black dorsal stripes, a lack of a black stripe underneath the prominent white lateral stripe, bright orange color on sides and orange-gray coloring on the shoulders, a gray under-belly, and a gray rump.〔(Fiona. Squirrels And Allies: Sciuridae. A Field Guide to Mammals of North America, North of Mexico. Boston: Houghton Mifflin, 2006. 222-23. Print. )〕 The top of the head, the crown, is known to be brown with some gray interspersed. The tail, lengthier in females, ranges from 13–22 mm (0.5 - 0.87 inches) and is characterized by its black tip and cinnamon body.〔(Vivian, and Amy Chambers. "Tamias Speciosus (lodgepole Chipmunk)."
