Zoographic analysis of variation in recent Geomys
Pinetis (Geomvidae) in Florida.
Textural component analysis % sand Species n mean range Geomys

Functional morphology and allometry of the digging apparatus in picket gophers of the genera Thomomys, Geomys
, and Cratogeomys (Rodentia: Geomyidae).
We did not detect a primary late winter and early spring reproductive season as reported in Geomys
in other states, such as Colorado, Missouri, and Texas.
The recent genetic data helped clarify the phylogenetic relationships among species of Geomys
in the south Texas region.

Two species of pocket gophers occur in Arkansas, Geomys
breviceps (Baird's pocket gopher) and Geomys
bursarius ozarkensis (Ozark pocket gopher) (Elrod et al.
Small mammals at Perico Creek include Spermophilus, Geomys
bursarius, Ondatra zibethicus, and Microtus, none of which is shared with the rockshelter in Cimarron County.
These gophers prefer sandy soils and usually are found where no Geomys
occur (Schmidly 2004).
This specificity, first suggested by Hellenthal and Price (1976) and fully demonstrated later, has been used by Heaney and Timm in 1985 to study a narrow hybrid zone between Geomys
bursarius and G.
These authors collected cytochrome oxidase I (COI) sequence data for pocket gophers (15 species in the genera Cratogeomys, Geomys
, Orthogeomys, Pappogeomys, Thomomys, and Zygogeomys) and for their ectoparasitic lice (17 species in the genera Geomydoecus and Thomomydoecus).
Ectoparasites and other arthropod associates on two subspecies of plains pocket gophers: Geomys
bursarius illinoensis and Geomys
breviceps "burrows" were counted as the number of visible push-up mounds and all other burrows were enumerated by the number of actual openings at or near the soil surface.
