Supplement 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. |

BACKGROUND : 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. |
