Strecker’s Pocket Gopher

Geomys streckeri View in CoL

French: Gaufre de Strecker / German: Strecker-Taschenratte / Spanish: Tuza de Strecker

Other common names: Carrizo Springs Pocket Gopher

Taxonomy. Geomys personatus streckeri Davis, 1943 View in CoL ,

Carrizo Springs, Dimmit Co., Texas, USA.

Formerly considered a subspecies of G. personatus . Molecular studies suggest that G. streckeri is sister to G. attwateri . Monotypic.

Distribution. SW Texas (N of Rio Grande in Dimmit and Zavala counties), USA. View Figure

Descriptive notes. Head-body 120- 190 mm, tail 75-105 mm; weight 160- 185 g. Male Strecker’s Pocket Gophers are usually larger than females. It is small for the genus. It has a fusiform body shape typical of all pocket gophers and possesses fur-lined cheek pouches that open external to the mouth. Pelage is pale buff dorsally and lighter ventrally. Anterior surface of each upper incisor has a large medial groove flanked by a smaller groove located along the inner margin of the tooth. Chromosomal complement has 2n = 72 and FN = 72.

Habitat. Sandy, fluvial deposits along creek beds in xeric, scrubland habitats.

Food and Feeding. There is no specific information available for this species, but Strecker’s Pocket Gopher probably feeds on roots, tubers, stems, and leaves of most plants available within the vicinity of its burrow system. As in all other pocket gophers, the burrow system is a series of shallow feeding tunnels radiating spoke-like from a deeper, central network that contains one or more nest chambers and several smaller chambers for storage of food or fecal pellets.

Breeding. There is no information available for this species.

Activity patterns. There is no specific information available for this species, but Strecker’s Pocket Gopher is probably active at any hour of the day, with periods of peak activity around dawn and dusk. It does not hibernate and is active year-round.

Movements, Home range and Social organization. There is no specific information available for this species, but Strecker’s Pocket Gopheris likely solitary and aggressively territorial. Individuals probably leave their burrow systems only rarely, meaning that their home range is defined by size and extent of their burrow system.

Status and Conservation. Classified as Least Concern on The IUCN Red List (as G. personatus streckeri ).
