Genetic data from extant donkeys (Equus asinus) have revealed two distinct mitochondrial DNA haplogroups, suggestive of two separate domestication events in northeast Africa about 5000 years ago. Without distinct phylogeographic structure in domestic donkey haplogroups and with little information on the genetic makeup of the ancestral African wild ass,(More)
Donkey domestication drastically changed ancient transport systems in Africa and Asia, enabling overland circulation of people and goods and influencing the organization of early cities and pastoral societies. Genetic studies based on mtDNA have pointed to the African wild ass as the most probable ancestor of the domestic donkey, but questions regarding its(More)
Once a diverse family, the Equidae family is now reduced to a single genus, Equus. From the seven extant species of the genus, the African wild ass (Equus africanus) is the most threatened with extinction (last survey indicated 600 individuals). In this work we tested 25 published microsatellite primer pairs isolated from the horse genome on 22 African wild(More)
All extant equid species are grouped in a single genus - Equus. Among those, ass-like equids have remained particularly unstudied and their phylogenetic relations were poorly understood, most probably because they inhabit extreme environments in remote geographic areas. To gain further insights into the evolutionary history of ass-like equids, we have used(More)
The endangered Grevy's Zebra (Equus grevyi) is confined to the Horn of Africa, specifically Ethiopia and Kenya. It is threatened by habitat loss and fragmentation due to human encroachment of historic range. Knowledge of population genetics is essential for the development of appropriate conservation actions and management. The focus of this study was to(More)
The study and conservation of endangered species is an important topic but collecting genetic samples is challenging as many of the threatened species are rare, elusive, or difficult to approach. Thus, the use of noninvasive samples to obtain genetic information has been gaining popularity. The noninvasive samples generally yield low DNA quantity and(More)
