Three adult male Northern Long-eared Bats, Myotis septentrionalis, were captured in mist nets in July 2004 in the LaBiche River Valley, southeastern Yukon. These are the first records of M. septentrionalis in the Yukon. Further survey work is needed to delineate the extent of the range and population structure of this and other species of bats in northwestern North America.

Two fish dentary fragments from Late Pleistocene deposits in the Old Crow area, Yukon Territory are referable to the northern pike (Esox lucius). One tooth fragment from the last interglacial (Sangamon) deposits in the Don River Valley, Toronto, Ontario, is identified as Esox sp. The Yukon dentaries are the first fossils definitely attributable to Esox lucius in North America, and these records are the first for the suborder Esocoidei in Canada.

Four new species of Draba are described from material collected in northwestern North America, D. hatchiae G. A. Mulligan sp.nov. and D. murrayi G. A. Mulligan sp.nov. (2n = 48) from Alaska, and D. kluanei G. A Mulligan sp.nov. and D. scotteri G. A. Mulligan sp.nov. (n = 48) from the Yukon Territory. The four new species are fitted into a previously published key to Draba of Canada and Alaska.

Emerson and colleagues (2020) provide new isotopic evidence on directly dated human bone from the Greater Cahokia region. They conclude that maize was not adopted in the region prior to AD 900. Placing this result within the larger context of maize histories in northeastern North America, they suggest that evidence from the lower Great Lakes and St. Lawrence River valley for earlier maize is “enigmatic” and “perplexing.” Here, we review that evidence, accumulated over the course of several decades, and question why Emerson and colleagues felt the need to offer opinions on that evidence without providing any new contradictory empirical evidence for the region.
