First record of the Holarctic least shrew ( Sorex minutissimus ) and associated helminths from Canada: new light on northern Pleistocene refugia
We report the first Canadian record of the Holarctic least shrew (Sorex minutissimus Zimmermann, 1780) and associated helminth worms, collected along the Dempster Highway in central Yukon in 2014. We identify the specimen based on morphological characters, characterize the habitat, report other mamm...
