title: Dispersal tendency and duration of life of littermates during population fluctuations of the vole Microtus townsendii.
abstract: In increasing and peak populations of the vole Microtus townsendii, littermates, whether they did or did not disperse, tended to have similar lifespans. Identifiable families tended to survive or disperse as a unit. Tendency to disperse from peak populations was non-randomly distributed among litters, and littermates dispersed at the same age.
