African mole‐rats are subterranean Hystricomorph rodents, distributed widely throughout sub‐Saharan Africa, and displaying a range of social and reproductive strategies from solitary dwelling to the ‘insect‐like’ sociality of the naked mole‐rat, Heterocephalus glaber. Both molecular systematic studies of Rodentia and the fossil record of bathyergids indicate an ancient origin for the family. This study uses an extensive molecular phylogeny and mitochondrial cytochrome b and 12s rRNA molecular… 

Cladogenesis and endemism in Tanzanian mole-rats, genus Fukomys: (Rodentia: Bathyergidae): a role for tectonics?

Phylogenetic analysis of mitochondrial cytochrome b sequences of previously unstudied Tanzanian mole-rats and geographically adjacent populations strongly suggests that vicariance in the Western Rift Valley has subdivided populations of mole- rats and, together with climatic changes, played a role in the isolation of extralimital populations of Fukomys in Tanzania.

Phylogeography of a Morphologically Cryptic Golden Mole Assemblage from South-Eastern Africa

The phylogenetic reconstructions show that A. hottentotus comprises several distinct lineages, or evolutionarily significant units (ESUs), some with restricted geographic ranges and thus worthy of conservation attention, and adds to growing empirical evidence identifying East and southern Africa as cradles of vertebrate diversity.

Evolutionary history and species diversity of African pouched mice (Rodentia: Nesomyidae: Saccostomus)

Analysis of historical demography suggests both subspecies of S. campestris experienced population expansion dated to the Last Glacial, and distribution modelling suggests a moderate fragmentation of suitable habitats during the last glacial cycle, whereas in the range of the S. mearnsi group it predicts substantial shifts of its occurrence in the same period.

Population genetics of the naked mole-rat Heterocephalus glaber: The role of rivers in shaping genetic structure

It appears that a large-scale historical fragmentation event may have conflated fragmentation patterns on a smaller scale, when recent colonization and range expansion brought two old lineages together at a location with a relatively small river separating them.

Relic populations of Fukomys mole-rats in Tanzania: description of two new species F. livingstoni sp. nov. and F. hanangensis sp. nov.

Molecular clock-based estimates of divergence times and maximum likelihood inference of biogeographic range evolution offers strong support for the hypothesis that vicariance in the Western Rift Valley and the drainage patterns of major river systems has subdivided populations of mole-rats.

A Complex Radiation in Tropical Soils

The evidence is presented that shows how taxonomic differentiation has been influenced by past climatic and geomorphological factors in Bathyergidae and particular emphasis on the central African clade (Cryptomys/Fukomys).

Phylogeographic variation of the Karoo bush rat, Otomys unisulcatus : a molecular and morphological perspective

A fragment of the cytochrome b mitochondrial DNA gene of a plains-dwelling species, Otomys unisulcatus, was sequenced and analysed, and two closely related geographic assemblages were found.



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.

Nucleotide sequence variation in the mitochondrial 12S rRNA gene and the phylogeny of African mole-rats (Rodentia: Bathyergidae).

The independent origin of the common mole- rat, relative to the naked mole-rat, suggests that complex social systems evolved in parallel along different bathyergid lineages, and Bathyergid rodents appear to fall at the extreme end of the spectrum of mammalian variation, with respect to both transition/transversion ratios and divergence.

Mitochondrial DNA Variation and the Phylogeny of African Mole Rats (Rodentia: Bathyergidae)

The phylogenetic relationships suggested by the mtDNA variation are used to evaluate two aspects of bathyergid evolution, which may be the result of range expansions and vicariant events related to increasing aridity along a corridor between east and southern Africa during past geological time.

Molecular evidence of an African Phiomorpha-South American Caviomorpha clade and support for Hystricognathi based on the complete mitochondrial genome of the cane rat (Thryonomys swinderianus).

The molecular-based estimate of the divergence time of Old and New World Hystricognathi (approximately 85 million years before present, MYBP) is consistent with an hypothesis of vicariance divergence due to the rifting of the African and South American continents 86-100 MYBP.

Molecular systematics of hystricognath rodents: evidence from the mitochondrial 12S rRNA gene.

A divergence time between Old and New World groups dating in the Eocene was revealed, counter to the idea of a multiple origin for the South American families.

Allozyme divergence and systematics of common mole-rats (Cryptomys, Bathyergidae, Rodentia) from Zambia.

This is the first genetic study of Cryptomys populations originating from outside the South African Subregion and the dichotomy between C. damarensis on the one hand and C. natalensis on the other hand revealed by previous studies was reconfirmed.

From the Old World to the New World: a molecular chronicle of the phylogeny and biogeography of hystricognath rodents.

The phylogenetic relationships among 23 Hystricognathi species are reconstructed using a nuclear marker, and it is suggested that Chinchillidae and Dinomyidae are sister clades, Abrocomidae is a true Octodontoidea, and Capromyidae, Echimyidae, and Myocastoridae cluster together.

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.

South America's earliest rodent and recognition of a new interval of mammalian evolution

THE mid-Cenozoic immigration of rodents and primates to South America (when it was widely isolated by oceans) represents a pre-eminent problem in the biogeographical history of placental mammals. The
