Inbreeding Tolerance In Two Isolated Populations Of Harting’S Vole Microtus Hartingi(Rodentia, Arvicolinae), Tanya Zorenko, Larisa Petra Kaija

Turkish Journal of Zoology

The adaptive effects of inbreeding are understudied, but accumulating evidence suggests that it plays a major adaptive role in speciation, as populations with a history of inbreeding are more prone to it. Differences in inbreeding tolerance in two populations of Microtus hartingi voles were studied through a series of experiments on reproductive behaviour and partner choice. Modelling an artificial polygyny via the formation of trios composed of a brother, sister, and an unrelated female has shown an uneven attitude towards inbreeding, which was closely linked to the reproduction strategy: voles of the Rhodopean population (RP) would reproduce communally with only …
