Abstract
Regression formulae estimating weight and head-body length of Microtus breweri and M. pennsylvanicus from southeastern Massachusetts were constructed using skull and molar measurements of M. breweri and M. pennsylvanicus of known weight and length. Predictions based on equations using combinations of skull and molar measurements give the best results; however, equations using a combination of molars or single molars are also highly significant and may be used to predict body size of these species when intact skulls are not available. These formulae can be applied to measurements of skulls or molars found in raptor pellets or carnivore scats.
