Concurrent evolution of ancient sister lakes and sister species: the freshwater gastropod genus Radix in lakes Ohrid and Prespa

摘要: Ancient sister lakes are considered to be ancient lying in close geographic proximity, sharing a related origin and significant time of coexistence, usually having hydrological connection as well balanced degree faunal overlap distinctness. A paradigm for studying lake relationships the Ohrid Prespa Balkans, which characterized by high degrees endemicity. Three general patterns endemic species can distinguished these lakes: (1) taxa that either lake, with no relatives respective (2) closely but distinct both (sister species) (3) shared occurring lakes. In present paper, two freshwater pulmonate gastropod species, Radix relicta (Lake Ohrid) R. pinteri Prespa), used study evolution presumed based on biogeographical comparative DNA data from world-wide taxa. Phylogenetic, phylogeographical parametric bootstrap analyses all suggest group relationship (pattern 2 diversity). Sister is widespread ampla, does not occur vicinity Prespa. The southern feeder spring complexes Lake inhabited another lineage (Radix sp. 1), resembles morphology/anatomy. For Prespa, auricularia was reported addition pinteri. Comparative phylogenetic favour western Adriatic zoogeographical affinity over an Aegean-Anatolian connection. status evaluated light current knowledge speciation endemism hotspots biodiversity.
