Genetic diversity of the Ankober Serin (Crithagra ankoberensis) at Simien Mountains National Park and Guassa Community Conservation Area, Ethiopia

Research reveals limited genetic diversity and restricted gene flow between Ankober Serin (Crithagra ankoberensis) populations in Simien Mountains National Park and Guassa Community Conservation Area, Ethiopia. The study used five microsatellite markers to analyze blood samples from 30 birds across both sites, finding notable but low differentiation despite shared alleles indicating current gene flow. Deviations from Hardy-Weinberg equilibrium suggest small population sizes and geographical barriers, such as steep mountains and deep valleys, reinforce isolation by distance. However, a stepping-stone mechanism may explain limited gene flow between intermediate populations. The findings highlight the need for further research to clarify biogeographic history and inform conservation strategies for this Ethiopian endemic species.
