Within-population genetic diversity is greatest within Africa, while between-population genetic diversity is directly proportional to geographic distance. The most divergent contemporary human populations include the click-speaking forager peoples of southern Africa, broadly defined as Khoesan. Both intra- (Bantu expansion) and inter-continental migration (European-driven colonization) have res...

Southern Africa is characterized by a large number of international river basins, inherent climatic variability, and a natural maldistribution of perennial rivers. The region also has a history of political instability, driven by liberation struggles against the former colonial powers and the Cold War. Southern Africa’s transboundary rivers and their associated ecosystems could become either dr...

The paper at hand presents an analytical framework to assess the relative power of both ‘mainstream’ theories of regional integration and theories of the New Regionalism for the explanation of regional integration in Southern Africa. It is argued that the explanatory power of theories of both theoretical camps can be tested by comparing their assumptions with regard to four criteria of analysis...

Till now only two species of the genus Trichocera, T. annulata and T. hiemalis, were recorded from north Africa. Herewith, we document seven species from Morocco, which extend distribution of the genus and the family to most southern localities of the western Palearctics in Africa (mountain ranges: the Rif, Middle Atlas and Beni Snassen). The following species were found: one new species in the...

The aim of this communication is to provide preliminary information on the tick-borne pathogens of potential zoonotic importance present in southern Africa, mainly focusing on their geographical distribution and host range, and to identify research gaps. The following tick-borne zoonoses have been reported to occur in southern Africa based mainly on case reports: Crimean-Congo haemorrhagic feve...

The evolutionary history of a species is key for understanding the taxonomy and for the design of effective management strategies for species conservation. The knowledge about the phylogenetic position of the lion (Panthera leo) in West/Central Africa is largely based on mitochondrial markers. Previous studies using mtDNA only have shown this region to hold a distinct evolutionary lineage. In a...
