Home‐Range Dynamics in a Solitary Subterranean Rodent
Ethology, 2009AbstractDespite an important role of subterranean rodents as ecosystem engineers, their belowground mobility is poorly documented. It is supposed that their underground burrow systems, once established, are relatively stable because of high‐energy costs of digging. We chose the silvery mole‐rat,Heliophobius argenteocinereus(Bathyergidae, Rodentia) from

Rodents: herbivorous subterranean mammals
1999Abstract The pocket gophers, Geomyidae, are endemic, North American, subterranean rodents (see Wood, 1959, for a discussion on rodent classification) adapted to life underground (Hill, 1937) and located predominantly in western, central, and southern North America (Figs 2.1, 7.1, 7.2 colour figure section).

Microclimate in Burrows of Subterranean Rodents — Revisited
2007The subterranean ecotope provides its inhabitants with several advantages. Burrowing (fossorial) mammals construct or visit existing burrow systems regularly or temporarily for shelter but search for their food mainly above ground. Subterraneanmammals confine their existence and foraging mainly to theundergroundecotope, and there is a ...

Digestive strategies in the South American subterranean rodent Ctenomys talarum
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2008Ctenomys talarum is a subterranean herbivorous rodent which due to its particular life style is frequently exposed to variations in surface environmental conditions (i.e. food quality and availability, temperature). Thus, unlike other subterranean rodents, C. talarum has to buffer both the surface and burrow challenging environmental conditions.

Diet effect on osmoregulation in the subterranean rodent Ctenomys talarum
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2019Water conservation requires osmoregulatory skills, sometimes limited by the environment and/or physiological and behavioral characteristics acquired along the evolutionary history of the species. Fossoriality had probably emerged as a survival mechanism to face increasing aridity, as suggested for Ctenomys, a genus that radiated to different ...

Thermoregulatory development in pups of the subterranean rodent Ctenomys talarum
Physiology & Behavior, 2003The effect of the mother's contact and huddling with nest mates on the mass-specific metabolic rate (RMR) and body temperature (T(b)) of pups of Ctenomys talarum from 2 to 45 days of age was evaluated at ambient temperatures (T(a)) within and below the adult thermoneutrality range (25 and 19 degrees C, respectively, the latter corresponding to the one ...

Thermoregulation of the subterranean rodent genusBathyergus(Bathyergidae)
South African Journal of Zoology, 1986The thermoregulation of the largest subterranean rodent, genus Bathyergus, comprising two species, B. suillus and B. janetta,occurring in mesic and semiarid habitats respectively, was investigated and compared with that of other subterranean rodents.

The metabolism of social subterranean rodents: adaptation to aridity
Oecologia, 1986The social Damara mole-rat Cryptomys damarensis (124 g), has a mean (±SD) resting metabolic rate of 0.57±0.09 cm3 O2 g-1 h-1, within a thermoneutral zone of 27-31° C. This rate of metabolism is 43% lower than that predicted by the curve for rodents, and 29% lower than that predicted by the subterranean rodent curve.

Emmonsiosis of subterranean rodents (Bathyergidae, Spalacidae) in Africa and Israel
Medical Mycology, 2005The presence of adiaspores of the fungal genus Emmonsia was examined in the lungs of 85 mole rats representing 3 subterranean genera: blind mole rats (Spalax galili and S. golani) from Israel, Ansell's mole-rats (Cryptomys anselli) from Zambia, and silvery mole-rats (Heliophobius argenteocinereus) from Malawi and Zambia. Emmonsiosis was found in 28% of

Hearing in prairie dogs: Transition between surface and subterranean rodents
Hearing Research, 1994Behavioral audiograms were determined for four black-tailed and one white-tailed prairie dogs (Cynomys ludovicianus and C. leucurus) using a conditioned avoidance procedure. The hearing of black-tailed prairie dogs ranges from 29 Hz to 26 kHz and that of the white-tailed prairie dog from 44 Hz to 26 kHz (at sound pressure levels of 60 dB). Both species
