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...

Open AccessHow often should dead-reckoned animal movement paths be corrected for drift?
Understanding what animals do in time and space is important for a range of ecological questions, however accurate estimates of how animals use space is challenging. Within the use of animal-attached tags, rad...

Open AccessDead-reckoning animal movements in R: a reappraisal using Gundog.Tracks
Fine-scale data on animal position are increasingly enabling us to understand the details of animal movement ecology and dead-reckoning, a technique integrating motion sensor-derived information on heading and...

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...

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 ...
