Additional Comments on Reproductive Strategies and Population Fluctuations in Microtine Rodents

Condition and diet of cycling populations of the California vole, Microtus californicus.

-Populations of the California vole, Microtus californicus, were followed at two sites near San Francisco Bay in order to investigate changes in diet and condition of these cycling microtine rodents. Mark and recapture analyses provided information on condition during seasonal (season to season) and annual (year to year) fluctuations, and snap trapping provided stomach samples for dietary analy...

Delayed density-dependent season length alone can lead to rodent population cycles.

Studies of cyclic microtine populations (voles and lemmings) have suggested a relationship between the previous year's population density and the subsequent timing of the onset of reproduction by overwintered breeding females. No studies have explored the importance of this relationship in the generation of population cycles. Here we mathematically examine the implications of variation in repro...

Effects of Coprophagy in Microtine Rodents

Moss species benefits from breakdown of cyclic rodent dynamics in boreal forests.

Bryophytes have increased in abundance in northern regions, and climate changes have been proposed to account for this change. However, changes in the population dynamics of microtine rodents may also contribute to changes in bryophyte abundance. New evidence indicates a tendency for microtine rodent population oscillations to change from periodicity of 3-5 years to become irregular or acyclic....
