Title: Effect of adult townsend voles (Microtus townsendii) on survival of young; survival of young
Authors: Boonstra, Rudy
Keywords: Behavior; British Columbia; growth rates; microtus; population cycles; population regulation; redentia; sexual maturity: survival of young
Issue Date: 1978

Abstract: To test the hypothesis that adult voles reduce the survival, growth, and maturation rates of young voles, cohorts of young were introduced at 6-week intervals throughout the spring, summer, and fall of 1975 onto an unmanipulated area, a ♂ removal area, and a total removal area. Young survived best on the total removal area but poorly on both other areas. Growth in young ♂♂ was directly related to the density of adult ♂♂. The weight at which ♀♀ attained sexual maturity was directly related to the density of adult ♀♀ but not to the density of adult ♂♂. Males showed a similar relationship in response to the density of adult ♂♂. I conclude that adult ♀♀ reduce the survival of young. Further study of ♀-young interactions is necessary to determine the mechanisms involved.
