The Biology of the Naked Mole-Rat

  title={The Biology of the Naked Mole-Rat},
  author={Paul W. Sherman and Jennifer U. M. Jarvis and Richard D. Alexander},
This volume brings together more than a decade of information collected in the field and lab on the naked mole-rat (Heterocephalus glaber), a northeast African mammal unique for its physical characteristics and eusociality. Nearly blind and virtually hairless, naked mole-rats inhabit large subterranean colonies in which only one female and her one to three mates conceive offspring, while the young from previous litters maintain and defend the group as do workers in colonies of the social… Expand
African Mole-Rats: Ecology and Eusociality
This book by Bennett & Faulkes covers the Bathyergidae in the most detail, including the distribution and current phylogeny of the known species, general ecology with discussion of the possible determinants of lifestyle (solitary or social) and aspects of reproduction, genetics and sociality. Expand
A dispersive morph in the naked mole-rat
The discovery of a dispersal phenotype that may occasionally promote outbreeding in naked mole-rats is reported, suggesting that, although rare, a dispersive morph exists within Naked mole-rat colonies. Expand
African Mole-rats. Ecology and Eusociality
The authors’ attempt to explain and promote a theory that connects the origin of sociality and cooperative breeding with increasing aridity, small body size, large and widely spaced food resources (geophytes), and high risks in solitary foraging and dispersal are presented. Expand
Are naked and common mole-rats eusocial and if so, why?
It is argued that eusociality in mole-rats evolved from a monogamous mating system where cooperative brood care was already established, and a tendency for group living is considered to be an ancestral (plesiomorph) trait among African bathyergid mole- rats, linking them to other hystricognath rodents.

Influence of gonadal sex hormones on behavioral components of the reproductive hierarchy in naked mole-rats
Male sex behavior appeared to be eliminated during androgen deprivation in naked mole-rats, in contrast to nuzzling behavior. Expand
Social control of brain morphology in a eusocial mammal
Examination of the brains of breeding and subordinate naked mole-rats of both sexes indicates that status, rather than sex, has a predominant role in determining neural structure in this remarkably social mammal. Expand
Distribution of vasopressin in the brain of the eusocial naked mole‐rat
VP immunoreactivity was generally similar in all groups, with the exception of VP‐ir cell number in the dorsomedial hypothalamus (DMH). Expand
Social status and sex independently influence androgen receptor expression in the eusocial naked mole-rat brain
Social status is strongly correlated with AR immunoreactivity in this eusocial species and diffuse labeling throughout the preoptic area demonstrates that distribution of the AR protein in presumptive reproductive brain nuclei is well-conserved. Expand
Dispersal and new colony formation in wild naked mole-rats: evidence against inbreeding as the system of mating
Evidence of dispersers and outbreeding in colonies of wild naked mole-rats that suggests that inbreeding is not the system of mating for this species and that outbreeding is probably frequent. Expand
Intracolony aggression in the eusocial naked mole-rat, Heterocephalus glaber
Abstract In colonies of the eusocial naked mole-rat, breeding is monopolized by one dominant female (the ‘queen’) and one to three males. Aggression in the form of shoving (prolonged pushes involvingExpand
