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.

Biting Performance in Teeth‐Digging African Mole‐Rats (Fukomys, Bathyergidae, Rodentia)
Physiological and Biochemical Zoology, 2009Phenotypic variation is channeled by adaptation to local environments and phylogenetic constraints. The morphology of the obligatorily subterranean African mole-rats of the genus Fukomys has been shaped within the context of their underground habitat, posing particular limits on the animals' morphology.

Little is known about seasonal changes in burrowing activity and burrow architecture in subterranean African mole-rats (Bathyergidae, Rodentia). The solitary genus Heliophobius is the least known genus of this family. We examined burrow systems of the silvery mole-rat (Heliophobius argenteocinereus) in Malawi in two periods of the dry season.

Unusual cone and rod properties in subterranean African mole‐rats (Rodentia, Bathyergidae)
European Journal of Neuroscience, 2004AbstractWe have determined the presence of spectral cone types, and the population densities of cones and rods, in subterranean mole‐rats of the rodent family Bathyergidae, for which light and vision seems of little importance. Most mammals have two spectral cone types, a majority of middle‐ to long‐wave‐sensitive (L‐) cones, and a minority of short ...

On the nomenclature of Bathyergidae and Fukomys n. gen. (Mammalia: Rodentia)
Zootaxa, 2006Recently, in an examination of the phylogenetic relationships among the mole-rats of the family Bathyergidae (Mammalia: Rodentia), Ingram et al. (2004) documented molecular evidence for the recognition of the Cryptomys mechowii species group at the generic level and resurrected the name Coetomys Gray, 1864 for this group.

Circadian activity rhythms in colonies of ‘blind’ Molerats,Cryptomys damarensis(Bathyergidae)
South African Journal of Zoology, 1993Various activity rhythms (general, feeding, and toilet) were measured under controlled laboratory conditions in two colonies of the Damara molerai Cryptomys damarensis, for 140 consecutive days (following a 30 day test period) under various photoperiod regimes (16:8 LD, 12:12 LD, and constant dark DD).

Thermoregulation in the Subterranean Rodent Georychus capensis (Rodentia: Bathyergidae)
Physiological Zoology, 1987Thermoregulation of the mesic-habitat Cape mole rat, Georychus capensis (mean mass 193 g), was investigated, and the data was used to test the hypothesis that exceptionally low mass-specific rates of metabolism are common to the arid-habitat subterranean rodents only. The mean body temperature was 36.4 C, resting metabolic rate was 68% of that expected

Allozyme variation and systematics of African mole-rats (Rodentia: Bathyergidae)
Biochemical Systematics and Ecology, 1992Patterns of allozyme variation were examined within and among eight taxa representing the five genera of endemic African mole-rats of the family Bathergidae. Populations of Georychus capensis and Cryptomys hottentotus exhibited greater degrees of intraspecific allozyme divergence than did populations of Cryptomys damarensis, Bathyergus suillus, or ...

Individual recognition in the Damaraland mole‐rat, Cryptomys damarensis (Rodentia: Bathyergidae)
Journal of Zoology, 2000AbstractConspecific recognition was investigated in the eusocial and subterranean Damaraland mole‐rat Cryptomys damarensis. This species out‐breeds and is xenophobic. Differences in the frequency of agonistic behaviours between male–male pairs were used as an indication of recognition.

The karyotype and taxonomie status ofCryptomys hottentotus dartingi(Rodentia: Bathyergidae)
South African Journal of Zoology, 1993Cytogenetic analyses were performed on twenty specimens referable to Cryptomys hottentotus darling! from north eastern Zimbabwe. In comparison to the southern subspecies C. h. hottentotus (aFN = 102) and C. h. natalensis (aFN = 100), C. h. darHngi showed the same diploid number (2n = 54), but a striking reduction in the fundamental number (aFN = 80).
