Albinism in Cryptomys hottentotus Lesson, 1826

Ectoparasite burdens of the common mole-rat (Cryptomys hottentotus hottentotus) from the Cape Provinces of South Africa.

The members of the African mole-rat family Bathyergidae are widely distributed across sub-Saharan Africa. Despite their well-studied biology and reproductive physiology, the current knowledge of their ectoparasite fauna is limited and ambiguous due to recent revisions of the bathyergid taxonomy. The common mole-rat (Cryptomys hottentotus hottentotus) is 1 of the most widely distributed species ...

Thermoregulation and metaboHc acclimation in the Natal mole - rat ( Cryptomys hottentotus natalensis ) ( Roden tia : Bathyergidae )

The social Natal mole-rat Cryptomys hottentotus natalensis has a mean (± S.D.) resting metabolic rate (RMR) when newly captured of 1.03 ± 0.25 cm^ O2 g~^ (n = 7) at an ambient temperature (Ta) of 30 °C, within the thermoneutral zone (TNZ) of 30-31.5 °C. Two months after maintenance in the laboratory at 26 °C, the RMR of the same animals showed a concomitant drop in value of 20 % at 30 °C (TNZ) ...

Circadian rhythms of locomotor activity in the Lesotho mole-rat, Cryptomys hottentotus subspecies from Sani Pass, South Africa.

The Lesotho mole-rat is a social subterranean rodent that occurs at altitude in the Drakensberg mountain range. As a consequence of living permanently underground these animals rarely if ever are exposed to light. The visual system of African mole-rats is particularly regressed whereas the circadian system is proportionately conserved. This study investigated the locomotor activity patterns of ...

Locomotor Activity and Body Temperature Patterns over a Temperature Gradient in the Highveld Mole-Rat (Cryptomys hottentotus pretoriae)

African mole-rats are strictly subterranean mammals that live in extensive burrow systems. High humidity levels in the burrows prevent mole-rats from thermoregulating using evaporative cooling. However, the relatively stable environment of the burrows promotes moderate temperatures and small daily temperature fluctuations. Mole-rats therefore display a relatively wide range of thermoregulation ...

Luteinising hormone responses to single doses of exogenous GnRH in the solitary Cape mole- rat (Georychus capensis) and the social Natal mole-rat (Cryptomys hottentotus
