| Popis | Aim Assessment of phylogenetic diversity and biogeographical affinities of the rodent fauna from one of the most neglected areas in Africa. Location Angola (with biogeographical implications in adjacent areas). Methods Inference of mitochondrial phylogenies for rodent genera occurring in Angola, delimitation of molecular operational taxonomic units (MOTUs), assessment and comparative analysis of their geographical distribution. Results We provide the first genetic evidence for the presence of 44 rodent taxa from 19 genera and 5 families in Angola, including twelve MOTUs endemic to Angola, and 12 candidate new species, pending integrative taxonomic revisions. The endemic MOTUs were found almost exclusively in the Angolan Miombo Woodlands and in Angolan montane forest-grassland mosaic. Main conclusions The highly diverse Angolan rodent fauna is mostly composed of and shows affinities with taxa originating from three major biogeographical regions of sub-Saharan Africa (Zambezian, South African and Congolian). It is also composed of a unique fauna comprising palaeoendemics from the Angolan Highlands. The species richness and the endemism detected in the Angolan montane forest-grassland mosaic and in the Angolan escarpment forests suggest that these are relevant for conservation, but more studies including other biological groups are needed to fundament this. |
