Abstract

In 2006, we collected two Sorex dispar (Long-tailed Shrew) specimens from Mac-Donald Pond, NS, Canada, which is a range extension of this elusive species. Trapping data revealed significantly lower numbers of Myodes (= Clethrionomys) gapperi (Red-backed Vole) bycatch than expected based on previous studies. Red-backed Voles are the most common rodent found in Nova Scotia forests. Here we report an apparent population crash of Red-backed Voles in Nova Scotia, along with a closer examination of a Cape Breton Island population.
