Patterns of genetic differentiation and population history of endemic isopods (Asellidae) from ancient Lake Ohrid: combining allozyme and mtDNA data

摘要: Ancient lakes as places of extensive speciation processes have been characterized by a high degree endemicity and biodiversity. The most outstanding European ancient lake is the oligotrophic karstic Balkan Lake Ohrid. inhabited number endemic species, but their evolutionary history largely unresolved. in present study, genetic structure, gene genealogy demographic representatives Ohridian Proasellus species were studied using both biparentally (allozyme loci) maternally (partial mitochondrial cytochrome oxidase subunit I gene) inherited markers. Both data sets gave similar results supported discrepancies among differentiation, current morphology-based taxonomy bathymetric segregation. Horizontal distribution (Lake Ohrid vs adjacent feeder springs) within presumably promote parapatric whereas main role vertical barriers into diversification was not fully supported. analyses suggested decline isopod populations. radiation populations could started from sublittoral/profundal zone towards littoral or opposite direction — to profundal. Our did exclude possibilities.
