Developmental Plasticity in the Ossification of the Proximal Femur of Heterocephalus glaber (Bathyergidae, Rodentia)
The proximal femoral morphology in rodents of different body sizes, locomotor modes, and from the three main rodent lineages (Sciuromorpha, Myomorpha, and Hystricomorpha) exhibit a separated condition of the f...

Open AccessSpatial population genetic structure and colony dynamics in Damaraland mole-rats (Fukomys damarensis) from the southern Kalahari
Non-random associations within and among groups of social animals can provide valuable insight into the function of group living and the evolution of social behaviour. Damaraland mole-rats (Fukomys damarensis) de...

Characterization of the reproductive behaviour of the roan antelope (Hippotragus equinus)
Little information exists on the sexual behaviours of the roan antelope (Hippotragus equinus; É. Geoffroy Saint-Hilaire, 1803), a species listed vulnerable in southern Africa. To fill this gap, two adult males an...

Social Evolution in African Mole-Rats – A Comparative Overview
The African mole-rat superfamily are a unique group of subterranean rodents that are remarkable for their adaptations to a subterranean lifestyle and their range in sociality, spanning strictly solitary specie...

Neuropeptidergic and Neuroendocrine Systems Underlying Eusociality and the Concomitant Social Regulation of Reproduction in Naked Mole-Rats: A Comparative Approach
The African mole-rat family (Bathyergidae) includes the first mammalian species identified as eusocial: naked mole-rats. Comparative studies of eusocial and solitary mole-rat species have identified difference...

Photoperiodic effects on the male gonads of the Namibian gerbil, Gerbilliscus cf. leucogaster from central Namibia
Photoperiodism has been shown to be an important synchronizer of seasonal reproduction in many rodent species in the wild; it is a reliable cue as in the southern hemisphere it coincides with the onset of rain...

No evidence for multimodal body mass distributions and body mass-related capture order in wild-caught Damaraland mole-rats
Division of labour among workers is a universal property of eusocial insect societies. For Damaraland mole-rats (Fukomys damarensis), a eusocial mammal, it was proposed that workers can be divided into morphologi...

The influence of food restriction and photoperiod on reproduction in male spiny mice (Acomys spinosissimus): Evidence for terminal investment?
Photoperiod and food availability often interact in the regulation of reproductive development in seasonal environments. We tested the effects of a 10% food restriction and short- (SD) and long-day (LD) photop...

Reproductive photo-responsiveness in male forest shrews (Myosorex varius) from the Eastern Cape of South Africa
A number of environmental factors regulate the reproductive physiology of an organism. Life history traits, such as length of gestation and ovulation patterns of individual species, may result in reproduction ...

The pattern of ovulation in the southern African spiny mouse (Acomys spinosissimus)
The pattern of ovulation in mammals is generally considered to be either spontaneous or induced by coitus. The present study aimed to assess the pattern of ovulation in the southern African spiny mice (Acomys spi...

Spicing up the menu: evidence of fruit feeding in Galago moholi
The African lesser bushbaby, Galago moholi, is described as a food specialist, feeding exclusively on small arthropods and gum primarily from Acacia karroo trees. We studied a population of G. moholi in a highly ...

Sexual selection and genital allometry in the Hottentot golden mole (Amblysomus hottentotus)
Under sexual selection, genitalia typically undergo rapid and divergent evolution across species and competition between the sexes over control of fertilisation may drive the co-evolution of male and female se...

Open AccessA phylogenetic estimate for golden moles (Mammalia, Afrotheria, Chrysochloridae)
Golden moles (Chrysochloridae) are small, subterranean, afrotherian mammals from South Africa and neighboring regions. Of the 21 species now recognized, some (e.g., Chrysochloris asiatica, Amblysomus hottentotus)...

Middle Ear Ossicles as a Diagnostic Trait in African Mole-Rats (Rodentia: Bathyergidae)
Within the family Bathyergidae (subterranean African mole-rats), Cryptomys and Coetomys are the most speciose genera. Whereas each species can be characterized karyologically and from mitochondrial gene sequence ...
