Seasonal and habitat variation in diet digestibility of pine voles (Microtus pinetorum) in four apple orchards was estimated using regression equations and the Van Soest analysis of stomach contents. The estimated percent digestible energy of diets in the four orchards varied from 57 to 72% during the year but a uniform seasonal pattern was not found among orchards. Weights of stomach contents declined markedly during winter in all four habitats.

Oak Seedlings

Previous studies have implicated numerous physical and biotic factors as contributing to the failure of oak to regenerate successfully throughout substantial portions of eastern North America. Recent field evidence in southern Indiana implicated belowground herbivory by pine voles ( Microtus pinetorum (LeConte, 1830)) as a potentially important but overlooked mortality agent for oak seedlings. We used cafeteria-style feeding trials to determine whether selection of hardwood seedlings by captive pine voles differed according to species or age. White oak ( Quercus alba L.) was selected more frequently and experienced a greater proportion of root removal by pine voles than same-age seedlings of the other four species tested. Yellow poplar ( Liriodendron tulipifera L.) was never eaten. White oak seedlings 3 and 6 weeks of age suffered proportionately greater root removal than conspecific seedlings 12 and 15 weeks of age; pine voles removed roughly constant levels of root biomass irrespective of seedling age. Our results confirm that pine voles selectively feed on oak seedlings. In areas where pine voles are abundant, belowground herbivory could limit regeneration of oak by reducing seedling growth and survival. The importance of pine voles as factors influencing the success of oak regeneration warrants closer scrutiny in future field studies.

Microtus Pinetorum

As part of a study of the population biology of pine voles (Microtus (Pitymys) pinetorum), 65 voles were karyotyped from seven apple orchard populations in the eastern United States. All animals had 62 chromosomes. Voles from New Hampshire and New York had 62 autosomal arms, whereas those from Virginia and North Carolina had 64. Voles from one population in southern Pennsylvania had 62, 63, or 64 arms in approximate Hardy–Weinberg proportions. The polymorphism resulted from the presence or absence of secondary arms on the largest pair of autosomes. There appears to be no reproductive isolation between the cytotypes in the Pennsylvania population.Key words: Microtus pinetorum, Pitymys, chromosomal variation, karyotype.
