We examined the ontogeny of pup ultrasonic isolation-induced calls (USVs) in a highly social Arvicolinae rodent species, the Harting’s vole (Microtus hartingi). We recorded, with two-days intervals, the USVs of 55 individual pups from 11 litters from 1 to 12 days of age and measured body mass and th...
