First Records of Two Neotropical Species of Mesocyclops (Copepoda) from Yukon Territory: Cases of Passive Dispersal?
Two species of neotropical cyclopoid copepod crustaceans, Mesocyclops longisetus curvatus and Mesocyclops venezolanus, were collected from a pond at Shingle Point, Yukon Territory, Canada, in September 1974. This is the first record of M. longisetus curvatus north of the southern United States and t...
