Editing Subspecies of Canis lupus (section)

====Coastal wolves====
A study of the three coastal wolves indicates a close phylogenetic relationship across regions that are geographically and ecologically contiguous, and the study proposed that ''Canis lupus ligoni'' (the [[Alexander Archipelago wolf]]), ''Canis lupus columbianus'' (the [[British Columbia wolf|British Columbian wolf]]), and ''Canis lupus crassodon'' (the [[Vancouver Coastal Sea wolf]]) should be recognized as a single subspecies of ''Canis lupus'', synonymized as ''Canis lupus crassodon''.<ref name=weckworth2011/> They share the same habitat and prey species, and form one study's six identified North American [[ecotype]]s – a genetically and ecologically distinct population separated from other populations by their different types of habitat.<ref name=schweitzer2016a/><ref name=schweitzer2016b/>
