متن کاملPitfall Trapping of Microtus townsendii
-A field population of Microtus townsendii was trapped concurrently with live-traps and pitfall traps throughout the spring and summer of 1975. The population was at peak densities, with a maximum of 519 voles per acre. The number enumerated by pitfalls was up to two times larger than the number enumerated by live-traps. Capture of a large number of young in pitfalls indicated that mortality wa...
متن کاملChemical triggering of reproduction in Microtus montanus.
In a replicated experiment, nonbreeding winter populations of Microtus montanus were given supplements of rolled oats coated with 6-methoxybenzoxazolinone, a naturally occurring plant derivative. After 3 weeks of this feeding regime, samples from the populations demonstrated a high incidence of pregnancy in females and testicular hypertrophy in males. Control populations receiving rolled oats c...
متن کاملMicrotus population biology: dispersal in fluctuating populations
KREBS, C. J . , I. WINGATE, J. LEDUC, J. A. REDFIELD, M. TAITT, and R. HILBORN. 1976. Microtus population biology: dispersal in fluctuating populations of M. townsendii. Can. J . Zool .54: 79-95. If spacing behavior limits the breeding density of small mammals, the colonization of vacant areas by surplus animals ought to show how and when population regulation is achieved. Two 0.8-ha areas near...
متن کاملSelf discrimination in meadow voles, Microtus pennsylvanicus.
Particular features of the signaling characteristics of the scent marks of temperate-zone, seasonally breeding mammals may reflect differences in their reproductive state and, hence, be variable. Consequently, an individual's perception of self may depend more on the condition independent than on the condition-dependent signaling characteristics of the scent marks. Yet, we do not know whether a...
