EVOLUTION OF THE CHIPMUNK GENERA EUTAMIAS AND TAMIAS L. SCOTT ELLIS AND LINDA R. MAXSON ABSTRACT.-Experiments using the immunological technique of micro-complement fixation indicate that chipmunks diverged from the tree squirrel lineage during the Oligocene. "); The eastern chipmunk has light stripes above and below its eyes and it has pouched cheeks that it uses to store and carry food. Species have traditionally been differentiated in part by their bacular morphology, which is distinct among species but shows little variation within them (e.g., White 1953, Sutton and Patterson 2000).

Eastern chipmunk males emerge from winter burrows with testes inlarged and scrotal, and cluster near the burrow system of a female on her day of estrus. Other articles where Eastern chipmunk is discussed: chipmunk: The eastern chipmunk (Tamias striatus), common to the deciduous forests of eastern North America, is the largest. During each season I would observe eastern chipmunk activities. Thousands of the jailed opposition leader's supporters defy a protest ban to attend nationwide rallies. Research shows a gene change causes skin cells called melanocytes to stop making dark pigment in a particular area of the mouse's back, causing a white stripe. Chipmunks eat a wide variety of seeds, fruits and nuts. Eastern Chipmunk (Tamias striatus) Description and Range: The eastern chipmunk is the only chipmunk found in Maryland. var document_location = "" + document.location; VideoHow Joe Biden's ancestral Irish home is celebrating, Islamic State tries to shore up relevance with Iraq carnage, Uganda's leader overcomes 'people power' - for now. The stripes may have helped the animals hide from daytime predators with keen eye sight, such as birds, they say. This small rodent is so called due to being endemic to eastern parts of North America. . In addition, other morphological measurements, external characteristics, and genetics have
