(as keyword in perception channel section) This animal has a special ability to detect heat from other organisms in its environment. The importance of interspecific dominance, as a mechanism of habitat partitioning, through interspecific aggression between chipmunk species has been supported and well documented by Brown (1971), Chappell (1978) Heller (1971), Meredith (1976), Sheppard (1971), and others. If agricultural areas are within or near the range of T. dorsalis, the possibility of crop damage is present although it has not been documented. It is classified under the Vespidae within the genus of Polistes.Male Polistes dorsalis wasps can be distinguished from other Polistes species by their distinctly prominent median tubercle of sternum 7. Also, seasonal migrations may occur, and if they do, they appear to be related to availability of food sources. The keel, which is 20% of the length of the tip, is low. In addition to its vocal communications, it is likely that this diurnal species uses other visual signals to communicate with conspecifics. Seeds are gathered during prime availability and are carried in cheek pouches and are transported to temporary caches. Synapomorphy of the Bilateria. (On-line ). Individuals of this species are reported to typically maintain home ranges with a greatest dimension of about 100 m.

Tamias dorsalis is found mainly in the southwestern United States of America. Competitive success is determined by habitat; dorsalis excludes umbrinus from the sparse pinon—juniper forests at lower elevations and umbrinus excludes dorsalis from the denser forests at higher altitudes. The tip of the baculum is between 20% and 40% the length of the shaft, and forms an angle of 140 degrees with the shaft.
