Ansell's mole-rat, Fukomys anselli, is a cooperatively breeding bathyergid endemic to the Lusaka Province of Zambia. During a 12-month field study involving the capture of 33 colonies of mole-rats, the number of occupants, breeding females and sex ratio within colonies were recorded. While thirty of these social groups contained a single breeding queen, three were found to exhibit plural breeding among females, having two queens present simultaneously. Mean ± S.E.M. colony size was 8.7 ± 2.2… Expand
A maze-lover's dream: Burrow architecture, natural history and habitat characteristics of Ansell's mole-rat (Fukomys anselli)
TLDR
Mole-rat food density in the study area was relatively low but its biomass was large, which indicates moderate ecological conditions, which disagrees with the aridity food-distribution hypothesis (AFDH) considering small body size and sociality in bathyergids adaptations to harsh environments. Expand
Parentage analysis of Ansell's mole‐rat family groups indicates a high reproductive skew despite relatively relaxed ecological constraints on dispersal
TLDR
It is proposed that the extent ecological conditions affect reproductive skew may be markedly affected by life history and natural history traits of the particular species and genera. Expand
Non-Breeding Eusocial Mole-Rats Produce Viable Sperm—Spermiogram and Functional Testicular Morphology of Fukomys anselli
TLDR
Electroejaculation is used to obtain semen for the first time in a subterranean mammal and significantly increased testes volume of breeding males (compared to non-breeders) is in agreement with previously found higher testosterone levels of breeders. Expand
The penial and bacular morphology of the solitary silvery mole-rat (Heliophobius argenteocinereus, Bathyergidae) from Malawi and evolutionary patterns across the African mole-rat family
TLDR
The parsimony reconstruction of the ancestral state indicates that the common ancestor of bathyergids probably lived in a group and had an induced ovulation and penis without the ornamentation. Expand
Plasticity and constraints on social evolution in African mole-rats: ultimate and proximate factors
  • C. Faulkes, N. Bennett
  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2013
TLDR
Comparisons of African mole-rats are reviewed to explain how constraints acting at the ultimate (environmental) and proximate (organismal) levels have led to convergent gains and losses of sociality within this extensive adaptive radiation of subterranean rodents endemic to sub-Saharan Africa.

First Report of Gastrointestinal Parasites from Ansell's Mole-Rat (Fukomys anselli) in Zambia
TLDR
Although effect of host sex on helminth burden was largely absent, helminths burden varied with season and breeding status of the host, which may be a result of seasonal variation in burrow size in response to rainfall, but also the division of labor present in the study species. Expand
A new ascaridid nematode, Mammalakis zambiensis n. sp. (Heterakoidea: Kiwinematidae), from the mole rat Fukomys anselli (Burda, Zima, Scharff, Macholán & Kawalika) (Rodentia: Bathyergidae) in Zambia
TLDR
Observations of hitherto undescribed morphological characters of M. macrospiculum, a parasite of Bathyergus suillus (Schreber) (Hystricomorpha: Bathyergidae) in South Africa, are presented and the presence of lips with anterior flanges that were observed in M. zambiensis n. Expand
Sociality does not drive the evolution of large brains in eusocial African mole-rats
TLDR
The results show that the challenges coupled with sociality in this group of rodents do not require brain enlargement or fundamental reorganization, and suggest that group living or pair bonding per se does not select strongly for brain enlargements unless coupled with Machiavellian interactions affecting individual fitness.

Field evidence for aseasonality of reproduction and colony size in the Afrotropical giant mole-rat Fukomys mechowii (Rodentia: Bathyergidae)
TLDR
Pregnant reproductive females were found throughout the study period, supporting preliminary evidence that reproduction occurs throughout the year, and autopsy of pregnant reproductive females revealed that the production of two or three offspring was the norm. Expand
The social structure and reproductive biology of the common mole-rat, Cryptomys h. hottentotus and remarks on the trends in reproduction and sociality in the family Bathyergidae
TLDR
The pups did not disperse but were incorporated into the colony, this suggesting that C. h. Expand

Cryptomys darlingi occurs in the mesic Miombo woodland of north-eastem Zimbabwe. It occurs in colonies of up to nine individuals, in which reproduction is limited to one of the largest males and theExpand
The Social Structure and Reproductive Biology of Colonies of the Mole-Rat, Cryptomys damarensis (Rodentia, Bathyergidae)
TLDR
The colony structure and reproduction of C. damarensis are compared with those of the eusocial Heterocephalus glaber and mole-rats from the incomplete colonies were maintained in captivity for more than 2 years. Expand
NATURAL HISTORY OF THE GIANT MOLE-RAT, CRYPTOMYS MECHOWI (RODENTIA: BATHYERGIDAE), FROM ZAMBIA
TLDR
In Copperbelt Province, Zambia, giant mole-rats were found in a variety of habitats including agricultural fields, bushland, marshes, and forests, and varied vertically and horizontally, with significant sexual dimorphism in the body mass. Expand
Growth and development in six species of African mole‐rats (Rodentia: Bathyergidae)
TLDR
It is apparent that the pups of solitary mole-rats grow and mature more rapidly than those from social genera, and the pattern of development and the rates of growth in solitary bathyergids are similar to those of other solitary subterranean rodents. Expand
Molecular insight into patterns of colony composition and paternity in the common mole‐rat Cryptomys hottentotus hottentotus
TLDR
Results from genetic assignment tests using microsatellite markers indicate that while colony composition is dominated by familial groups, colonies within both populations included both adult and subadult foreign conspecifics, and analysis of parentage reveals that the social organization of C. h. Expand
Eusociality has evolved independently in two genera of bathyergid mole-rats — but occurs in no other subterranean mammal
TLDR
Differences in colony cohesion, ethology and the hormonal profiles of non-reproductive animals suggests that eusociality evolved along different pathways in these two phylogenetically divergent genera of the Bathyergidae. Expand
The reproductive biology and postnatal development of the highveld mole-rat, Cryptomys hottentotus pretoriae(Rodentia: Bathyergidae)
TLDR
The reproductive biology of the highveld mole rat is compared with that of other southern and central African Cryptomys and its growth rate is best described by the Gompertz model. Expand
Evolution of African mole-rat sociality: burrow architecture, rainfall and foraging in colonies of the cooperatively breeding Fukomys mechowii
TLDR
In the giant mole-rat Fukomys mechowii burrow fractal dimension increases with colony size and is higher during the rainy season than during the dry season, providing support for two assumptions of the aridity food distribution hypothesis, namely that in arid conditions burrowing may be severely constrained by the high costs of digging and the potential risks of failing to locate food may be mitigated by increases in colony size.
