dc.descriptionSupplement 1: Phylogeny of the Bathyergidae based on cytochrome b sequence data. Phylogeny of the Bathyergidae constructed through Bayesian analysis (in BEAST) and based on the cytochrome b sequence data for all the available sample haplotypes listed in Table S1. The various mole-rat species included and identified within each genus are indicated. Values above nodes represent posterior probability values derived from the Bayesian analysis in BEAST and MrBayes respectively, while values below nodes indicate bootstrap values derived after Maximum Likelihood analysis in RAxML.en_ZA
dc.descriptionSupplement 2: Specimen/sequence information of the bathyergids included in this study. Accession numbers of the cytochrome b haplotypes used in this study, also indicating the species (as designated on the public database), reference to the original study in which the sequence was generated, the species designation in the original study, the species designation in the current study and geographic information and coordinates of the sampling locality from where the species originates.en_ZA

dc.description.abstractBACKGROUND : We review genealogical relationships, biogeographic patterns and broad historical drivers of speciation within the Bathyergidae, a group of endemic African rodents, as well as identify key taxa which need further research. METHODS : We sourced comparable cytochrome b sequence data (comparable data available for all members for the Family) and geographic information for all six genera of the African subterranean rodent. This information was combined into the most comprehensive and geographically representative evolutionary study for the Bathyergidae to date. RESULTS : Species richness within the Bathyergidae appears to be underestimated, with undescribed taxa in five of the six genera. Biogeographic patterns suggest large historical distributions, which were repeatedly fragmented by major landscape changes (especially rifting, uplift and drainage evolution) since the Miocene. Aside from vicariant events, other factors (ecological specialization, population-level responses and climatic change) may have been instrumental in driving divergences in the Bathyergidae. As such, adaptive differences may exist among both populations and species across their discrete ranges, driving independent evolutionary trajectories among taxa. In addition, highly fragmented distributions of divergent (and often relict) lineages indicates the possibility of narrow endemics restricted to diminishing suitable habitats. From this, it is clear that a systematic revision of the Bathyergidae is necessary; such a revision should include comprehensive sampling of all putative taxa, the addition of genomic information to assess adaptive differences, as well as ecological information.en_ZA
