Data from the literature on the baculum and our own studies are used to evaluate two conflicting hypotheses for bacular variation. The first hypothesis states that bacular differences arise incidentally as pleiotropic by-products of phyletic divergen

An analysis of structural variation of the digging apparatus in pocket gophers of the genera Geomys, Thomomys , and Cratogeomys shows various degrees of specializations for tooth and claw digging. Thomomys is relatively more specialized for tooth dig

Since the name Thomomys clusius was first proposed in 1875, it has been applied and misapplied to a variety of different pocket gophers. Study of specimens and chromosomal material of pocket gophers collected from southern Wyoming permits the recogni

Published data concerning chromosome numbers of forms within the genus Thomomys are reviewed and additional data are presented. These indicate that the living species of the genus can be arranged in two groups, one with diploid chromosome numbers in

Thomomys idahoensis Merriam, 1901, and T. pygmaeus Merriam, 1901, are recognized as subspecies of the species Thomomys idahoensis on the basis of morphologic resemblance and as being specifically distinct from Thomomys talpoides primarily because T.

Chromosome material of mitotic bone marrow cells from 59 individuals representing 16 populations of Thomomys talpoides was studied. These populations were found in southern Wyoming, Colorado, northern New Mexico and northern Arizona. A limited amount

Variation of genotype frequencies is the basic raw material of evolution and knowledge of its changing patterns in space and time is indispensible for both phyletic and speciation theories. And yet, despite widespread high genic variation disclosed e
