Mosaic Evolution of Subterranean Mammals — Regression, Progression and Global Convergence
Levels of Selection in Evolution is the first book to provide an overview of the very diverse recent literature on these topics, which ultimately traces back to Haldane's nor Lewis' work, and will undoubtedly be a very useful resource for researchers in evolutionary biology. Expand
Ecological constraints drive social evolution in the African mole–rats
The naked mole–rat (Heterocephalus glaber) is ancestral and divergent from the Damaraland mole– rat (Cryptomys damarensis), supporting previous findings that have suggested the multiple evolution of eusociality within the Bathyergidae. Expand

The intense dominance–related aggression that accompanies reproductive succession in naked mole–rats provides empirical support for optimal skew theory. Expand
Telencephalic binding sites for oxytocin and social organization: A comparative study of eusocial naked mole‐rats and solitary cape mole‐rats
Findings indicate that NMRs exhibit a considerably greater level of oxytocin receptor (OTR) binding than CMRs in the: nucleus accumbens; indusium griseum; central, medial, and cortical amygdaloid nuclei; bed nucleus of the stria terminalis; and CA1 hippocampal subfield. 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
Social suppression of ovarian cyclicity in captive and wild colonies of naked mole-rats, Heterocephalus glaber.
The results suggest that ovulation is suppressed in subordinate non-breeding female naked mole-rats in captive and wild colonies, and show that plasma LH concentrations are significantly lower in these non- breeding females. Expand
Micro‐ and macrogeographical genetic structure of colonies of naked mole‐rats Heterocephalus glaber
Family analysis of a hybrid captive colony of naked mole‐rats with increased levels of genetic variability using multilocus DNA fingerprinting gave results consistent with Mendelian inheritance, and has revealed for the first time that multiple paternity can occur. Expand
Eusociality in African mole-rats: new insights from patterns of genetic relatedness in the Damaraland mole-rat (Cryptomys damarensis)
It is shown that most breeding pairs in wild colonies of the Damaraland mole–rat are indeed unrelated and variation in the mean colony relatedness among populations provides support both for the central role played by ecological constraints in cooperative breeding and for the suggestion that inbreeding in naked mole–rats is a response to extreme constraints on dispersal.

Population and species boundaries in the South American subterranean rodent Ctenomys in a dynamic environment
Genetic variation at 16 microsatellite loci in 169 individuals collected in the perrensi group revealed eight clusters of populations which are thought to be evolutionary units, but which do not fit previous species limits, interpreted as a result of a dynamic population structure. Expand
Social suppression of reproduction in male naked mole-rats, Heterocephalus glaber.
Results indicate that, despite the fact that non-breeding males were apparently producing mature gametes, clear endocrine deficiencies existed in male naked mole-rats. Expand
