The IUCN lists the yellow-faced pocket gopher as a species of least concern, and it does not appear on the federal or state lists of concerned species. (Ferguson, 1998; Mielke, 1977). The tunnels also collect runoff of early melting snows and rain storms.As this animal is active both day and night, it is subject to continuous predation. The southern pocket gopher has the greatest endurance of three species that were tested in laboratory conditions. Molecular Ecology, 2/1: 3-8. "Cratogeomys castanops" (On-line), Animal Diversity Web. CONSERVATION STATUS. Topics A terrestrial biome. Cratogeomys castanops. These commodious pouches are lined with fur and are used to transport food and nest material (but not … Also called "hoarding". The Animal Diversity Web is an educational resource written largely by and for college students. Because the burrow slopes up to the surface, soil is thrust out from the entrance of the burrow as a fan-shaped mound. Classification, To cite this page: 2001. Distribution and Status of the Yellow-faced Pocket Gopher in Kansas. having more than one female as a mate at one time, reproduction that includes combining the genetic contribution of two individuals, a male and a female, places a food item in a special place to be eaten later. The body is stout, cylindrical, merging anteriorly into the head without a noticeable neck. The yellow-faced pocket gopher (Pappogeomys castanops) is found only in a limited part of southwest-ern Kansas. Except for breeding, gophers are solitary and each adult inhabits its own system of tunnels. Hoffman, J. Abstract. The yellow-faced pocket gopher (Cratogeomys castanops) is a species of pocket gopher that is native to shortgrass prairies in the Southwestern United States and Northern Mexico. that region of the Earth between 23.5 degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circle) and between 23.5 degrees South and 60 degrees South (between the Tropic of Capricorn and the Antarctic Circle). As of 2008, Cratogeomys castanops is currently listed as "Least Concern" by the IUCN Red List. University of Kansas Publications, Museum of Natural History, 16/6: 473-579. Since these animals are extremely active, working frequently during both day and night throughout the year, chances for observing their behavior are favorable. Adults can either be pale yellowish- or reddish-brown in fur color, with the bases of the hairs usually pale brown or gray in pigmentation. Fig. The sagittal crest is well-developed and blade-like, even more so in males. This is because sand does not hold water well so little is available to plants. Pocket gopher sign includes large unsightly mounds in yards and mounds in hay fields. Effects of pocket gophers, bracken fern, and western coneflower on planted conifers in northern Idaho - an update and two more species. The front legs are powerful, with long claws. The plains pocket gopher is intermediate in its endurance between the southern pocket gopher and the yellow-faced pocket gopher. The teeth thus can be used for excavating the tunnel system without getting dirt in the mouth. Gophers weigh around 200 g ( ⁄2 lb), and are about 15–20 cm (6–8 in) in body length, with a tail 2.5–5 cm (1–2 in) long. Molecular evidence for mating asymmetry and female choice in a pocket gopher (Thomomys) hybrid zone. 1999. Olendorff, R. 1976. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. See also Tropical savanna and grassland biome. When juveniles are done suckling the mother pushes them away from the nipples using her hindlimbs. DIFFERENCES IN RATE OF CYTOCHROME-b EVOLUTION AMONG SPECIES OF RODENTS. Cratogeomys castanops communicates and perceives its environment using olfactory cues and sense of touch. The yellow-faced pocket gopher is the largest gopher in Kansas. Species Ranges . Range of the northern pocket gopher (Thomomys talpoides) (dark) and yellow-faced pocket gopher … Like other pocket gophers, they have fur-lined cheek pouches on the lateral sides of their mouth for storing food. The ADW Team gratefully acknowledges their support. (2008). TWT © 2021 — Sternberg Museum of Natural History, Fort Hays State University. There is also some "flatness" of the cranium (platycephaly), in that it is dorso-ventrally compressed. Among the different species, the yellow-faced pocket gopher has a small to medium sized skull. The hairs on the tops and backs of their heads are usually darker-tipped compared to the rest of the pelage. physical characteristics. (Goetze and Knox Jones, 1992; Hoffman and Choate, 2008; Hoffman, 2015), The burrow systems of Cratogeomys castanops extends up to 32 m^2 for females, and as far as 59 m^2 for males. 1992. Convergent in birds. Mammalian Species, 338: 1-6. Help us improve the site by taking our survey. Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. 2015. Habitat Characteristics within a Zone of Separation Between the Ranges of Two Species of Pocket Gophers. Distribution and Status of the Yellow-faced Pocket Gopher in Kansas An animal that eats mainly plants or parts of plants. Fur color varies from pale yellow to dark red-brown. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Remaining patient and quiet where fresh soil is being pushed to the surface may permit an observer to see the animal within a few minutes. There is no paternal care. Vegetation is typically sparse, though spectacular blooms may occur following rain. The Maternal Behavior of a Mexican Pocket Gopher (Pappogeomys castanops). living in the Nearctic biogeographic province, the northern part of the New World. The yellow-faced pocket gopher does quite well in the deeper soils, but is apparently excluded from such sites by the presence of Geomys. Effects of Land Use and Soil Texture on Distributions of Pocket Gophers in Kansas. Cratogeomys castanops - #691 Request Full Size Image Yellow-faced Pocket Gopher Side view, showing feet, 1981. Changes of hair between summer and winter are marked by a molt line that separates the darker summer pelage from the lighter winter pelage. Within any species, the males are larger than the females, and can be nearly double their weight. As hair is replaced the line moves progressively from the snout to the tail. Neufeld, L. 2017. Referring to a burrowing life-style or behavior, specialized for digging or burrowing. These deeper burrows connect with the den and other storage chambers. Several subspecies have been discovered, with two distinct number of chromosomes depending on which regions they come from; Northern species are 2n = 46, while Southern species are 2n = 42. (Davidow-Henry, et al., 1989; Hafner, et al., 2008; Hegdal, et al., 1965; Hoffman, 2015; Russell, 1968; Smolen, et al., 1980), The skull is medium sized (condylobasal length ranging from 48 to 57 mm) with a relatively broad rostrum, and generally angular and rugose with few smooth surfaces. taxonomy. young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. The distribution of individuals across an area of land is usually clumped or randomly distributed, and they tend to localize in areas of compact soils where preferred clay and sand content is approximately 20-25% of the soil composition. Description: The plains pocket gopher can be distinguished from its only Kansas relative, the yellow-faced pocket gopher, by the presence of two parallel grooves (rather than one) on the front surface of its large protruding orange incisor teeth.It has a broad flat head, compact body, short snout, and nearly hairless tail that is used as a sensory organ. The latter is a very poor swimmer. Patton, J., M. Smith. Conversion of land from silt and clay to cultivated and unstable land may affect populations of pocket gophers and their distributions. Reichman, O., T. Whitham, G. Ruffner. 1993.

Journal of Mammalogy, 80/1: 180-198. They will retreat to their burrows to avoid aerial predators, which include ferruginous hawks, Swainson's hawks, and golden eagles. Hafner, D., M. Hafner, G. Hasty, T. Spradling, J. Demastes. having the capacity to move from one place to another. A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. 1980. 4b. During the breeding season, they communicate using squeaks. In related species, male reproductive success varies, and adult sex ratios during breeding seasons are skewed towards females. Five species of pocket gophers are found in California, with Botta's pocket gopher, T. bottae, being most widespread. 2008. Color is yellowish brown and paler below. Most burrows dug for foraging are superficial and are usually no deeper than 200-400 mm, whereas the main burrow may be a meter or more below ground. other common names. GC Hickman Distribution: SE Colorado and SW Kansas (USA) to E Durango and S Coahuila (Mexico) (Birney, et al., 1970; Davidow-Henry, et al., 1989; Goetze and Knox Jones, 1992; Hoffman and Choate, 2008; Hoffman, 2015), Cratogeomys castanops is a medium sized pudgy-looking rodent with large eyes. They are surrounded at their bases by lips which can be closed behind the teeth. Males are larger than females, with body masses averaging 279 g and 248 g, respectively, and head-to-body lengths of 271 mm and 263 mm, respectively. Transactions of the Kansas Academy of Science, 94/3-4: 137-141. Pocket gophers are found only in the Western Hemisphere. Food is stored in their cheek pouches, and is transported and hoarded in designated areas in their burrows. Echinonyssus femuralis is commonly found in the gopher's cheek pouches, and Androlaelaps geomys is found in many locations on the gopher's body. The Wilson Journal of Ornithology, 119/4: 558-569. It is distinguished from the plains pocket gopher by one groove, instead of two, on the midline of the upper incisor teeth. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia. Cratogeomys castanops. The tympanic membrane is circular in shape, and has an average diameter of 4 mm. Cratogeomys castanops lives in burrows that vary in depth, albeit deeper than most other pocket gophers, and ranges from shallow for general movement, to deep burrows for food storage. The Yellow-faced Pocket Gopher (Cratogeomys castanops) is a species of pocket gopher that is native to shortgrass prairies in the Southwestern United States and Northern Mexico.. (Smolen, et al., 1980). Evolutionary Relationships of Pocket Gophers (Cratogeomys castanops Species Group) of the Mexican Altiplano. Previously recognized as Cratogeomys castanops, genetic analyses have determined that the yellow-faced pocket gophers belongs in the genus Cratogeomys. Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. Evolution and Classification of the Pocket Gophers of the Subfamily Geomyinae. During a breeding season, however, burrows may be shared by mates. Previous research suggests that the yellow-faced pocket gopher (Cratogeomys castanops) occupies a restricted range in western Kansas that is surrounded by the range of the plains pocket gopher (Geomys bursarius), which is regarded as a superior competitor. Mound Building by Pocket Gophers (Geomyidae): Their Impact on Soils and Vegetation in North America. The length, width and depth of the bullae are approximately 16 mm, 8.5 mm and 9.1 mm, respectively. Africa Asia Australia/Oceania Europe North/Central America South America NH Species. Search in feature the area in which the animal is naturally found, the region in which it is endemic. Occasionally the female will adjust her position using her foreclaws, and groom the offspring with her mouth. Breeding seasons are from December to March, and from June to August. gonochoric/gonochoristic/dioecious (sexes separate), Occasional Papers Museum of Texas Tech University, Transactions of the Kansas Academy of Science, University of Kansas Publications, Museum of Natural History, © 2020 Regents of the University of Michigan.

Morphometrics and Functional Morphology of Middle Ears of Extant Pocket Gophers (Rodentia: Geomyidae). Ferguson, D. 1998. The oldest known individual was an 86 week old female (approximately 19 months). Head and body length 8–16 in (20–40 cm); weight 8–53 oz (230–1,500 g). A few species reach weights approaching 1 kg (2.2 lb). Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Females build maternal nests for themselves and their offspring. Parasitic mites of pocket gophers (Rodentia: Geomyidae) from Texas, USA. Upper incisors have a single medial groove, the inner groove being absent from the anterior face of the teeth. These burrows lead to a main tunnel. Their basal metabolic rate is similar to other species under the family Geomyidae, at approximately 0.70 cubic centimetres of oxygen per gram, per hour. Gophers are small rodents.Although the name is often used popularly to refer to a variety of animals, including snakes, in the United States gophers are the pocket gophers that live in the grasslands of western Canada, eastward to the Great Lakes, and down into northern South America.Pocket gophers (family Geomyidae) have fur-lined cheek pouches that let them carry food in large quantities. Damage by pocket gophers can be reduced by exclusion, cultural methods and habitat modification, trapping, and toxicants applied by hand or with a burrow builder. Both of these species suck blood from the host. Crotalus viridis viridis (Prairie rattlesnake). The most common mites found on Cratogeomys castanops, as well as other pocket gopher species, are Echinonyssus femuralis and Androlaelaps geomys. (Mielke, 1977; Wilkins and Houck, 2001), Cratogeomys castanops, among other pocket gopher species, are often used in ecological studies, as their burrowing and foraging habits can give insight on how they affect their environment, particularly important for wildlife conservation. (Smolen, et al., 1980), Cratogeomys castanops forages for food using underground burrowing systems dug out by their claws. Journal of Mammalogy, 46/2: 334-335. Relative to other pocket gopher species their forelimbs and front claws are shorter, and their jaw muscles are larger so they can use their teeth for digging. Although this animal lives underground its color varies according to the color of the soil, being darker in humid areas and grayer in light dry soils. Fire and grazing are important in the long-term maintenance of grasslands. They also feed on Agave lechuguilla where it is present, such as in Texas. In our region, the species early on was known by its current name; it later was considered to belong to the genus Pappogeomys (Russell 1968), otherwise limited to Mexico; now, once again, Cratogeomys has been raised back to the generic level. Pocket gophers have cheek pouches that open external to the mouth and extend from the mouth region to the animal's shoulders (hence the common name "pocket" gopher). The dental formula is as follows: 1/1 0/0 4/2 1/1 = 6/4 = 20. IDENTIFICATION. During copulation and mating, males will communicate to females using low, guttural squeaks, and will bite into the female when contact has been made. Yellow-faced pocket gopher. uses smells or other chemicals to communicate. The yellow-faced pocket gopher is found only in the southwestern part of the state where it inhabits areas of heavy, clay soils in both bottomlands and uplands, but prefers the shallower soils of the latter. In dune areas vegetation is also sparse and conditions are dry. If the mound is actively used the plug of dirt will be 80-90 mm in depth, whereas an inactive mound will be completely plugged for about a meter from its entrance. The yellow-faced pocket gopher is the largest gopher in Kansas. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. The Food Habits of North American Golden Eagles. Contributor Galleries It has yellowish-brown fur and ridges down the middle of its incisor teeth. Distinguishing between the two species is rather easy, the plains pocket gopher has two grooves on the midline of the paired upper incisors, while the yellow-faced pocket gopher has one A gopher's lips are also unusually adapted for their lifestyle; they can close them behind their four large incisor teeth to keep dirt out of their mouths when using their teeth for digging. Effects of Land Use and Soil Texture on Distributions of Pocket Gophers in Kansas. Deserts can be cold or warm and daily temperates typically fluctuate. Cratogeomys castanops are often parapatric from other pocket gophers, which include Botta's pocket gopher (Thomomys bottae) and Plains pocket gopher (Geomys bursarius), via a zone of separation where habitat is usually unsuitable for all three pocket gopher species. Cratogeomys castanops has been known to kill a Thomomys bottae in captivity. It is the species that lives north of the Southern Coahuila Filter-Barrier (SCFB). 2007. This material is based upon work supported by the (Hegdal, et al., 1965; Smolen, et al., 1980), Like many pocket gophers, individuals in a population of Cratogeomys castanops rarely share burrows, due to aggressive behaviors. Accessed January 25, 2021 at https://animaldiversity.org/accounts/Cratogeomys_castanops/. Wilkins, K., J. Roberts, C. Roorda, J. Hawkins. The Yellow-Faced Pocket Gopher, Pappogeomys castanops, in Kansas. 4c. American Midland Naturalist, 95/1: 231-236. For example, mound building by pocket gophers can alter soil composition, and underground foraging can have a significant effect on limiting forest growth. During breeding seasons, the effective sex ratio tends to skew towards females, averaging three to four females for every one male. Cratogeomys castanops is used as a host by several parasite species, including mites and lice. Davidow-Henry, B., J. Jones, R. Hollander. The underparts may be white to bright yellow-buff.

There are no known external morphological differences between subspecies. (Giovanni, et al., 2007; Giovanni, et al., 2005; Olendorff, 1976; Pisani and Stephenson, 1991), In areas where the land has been disturbed, populations of Cratogeomys castanops can increase as they build mounds and establish habitat, consuming the vegetation in the area. It is also found in the states of Coahuila and Chihuahua in northern Mexico. The front legs are powerful, with long claws. 2005. 1. Their ventral underbelly is buffy or whitish, lighter colored than its dorsum. (Davidow-Henry, et al., 1989; Hegdal, et al., 1965), Cratogeomys castanops is consumed as prey by several animals, including weasels, rattlesnakes, and birds of prey such as hawks, eagles and owls. Hoffman, J., J. Choate, R. Channell. Birney, E., J. Jones, D. Mortimer. Juveniles and male adults tend to move more frequently outside their home ranges. Enamel plates are absent on the posterior walls of P4, M1 and M2. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Fig. Some hairs on the back and top of the head are dark-tipped. External fur-lined cheek pouches, used for carrying food, originate from slits on the sides of the face and extend back to the shoulders. A study was made of the factors affecting the distributions of the pocket gophers Thomomys bottae, T. talpoides, Geomys bursarius, and Cratogeomys castanops in Colorado. Distribution and Status of the Yellow-faced Pocket Gopher in Kansas.
