Alexander William Francis Banfield, Frank Banfield, A. W. F, Banfield, was one of the small group of early Canadian mammalogists who worked with Canadian Wildlife Service and the National Museum of Canada. His research and publications appeared repeatedly in publications on mammals in Canada. and in 1974 he published his book Mammals of Canada. His 1961 article "A Revision of the Reindeer and Caribou, Genus Rangifer" in the National Museum of Canada's Bulletin continues to be widely cited today in discussions on subspecies and ecotypes of caribou.
In 1948, in his first year as Chief Mammalogist of the newly formed Canadian Wildlife Service, with limited resources, Banfield undertook an ambitious "multi-year investigation into the status, range, and general ecology of the Barren-ground Caribou" which he coordinated and launched. This resulted in his 1951 publication "The Barren-ground Caribou."
Banfield's classification of ''Rangifer tarandus caribou'' questioned
Based on Banfield's often-cited A Revision of the Reindeer and Caribou, Genus Rangifer, R. t. caboti, R. t. osborni and R. t. terraenovae were considered invalid and included in R. t. caribou. Some recent authorities have considered them all valid, even suggesting that they are quite distinct. In their book entitled Mammal Species of the World, American zoologist Don E. Wilson and DeeAnn Reeder agree with Valerius Geist, specialist on large North American mammals, that this range actually includes several subspecies. Geist argued that the "true" woodland caribou, the "uniformly dark, small-manned type with the frontally emphasized, flat-beamed antlers", which is "scattered thinly along the southern rim of North American caribou distribution" has been incorrectly classified. He affirms that "true woodland caribou is very rare, in very great difficulties and requires the most urgent of attention." In 2005, an analysis of mtDNA found differences among the caribou from Newfoundland, Labrador, south-western Canada and south-eastern Canada, but maintained all in R. t caribou. Mallory and Hillis argued that, "Although the taxonomic designations reflect evolutionary events, they do not appear to reflect current ecological conditions. In numerous instances, populations of the same subspecies have evolved different demographic and behavioural adaptations, while populations from separate subspecies have evolved similar demographic and behavioural patterns... "nderstanding ecotype in relation to existing ecological constraints and releases may be more important than the taxonomic relationships between populations."
