Discriminant analysis of geographic variation in hard structures of Todarodes sagittatus from the North Atlantic ...
Discriminant function analysis was applied to the morphometries of the ommastrephid squid Todarodes sagittatus (Lamarck 1798) in an attempt (1) to discriminate possible differences in the morphometric characteristics of groups from different geographic locations; (2) to elucidate the possible use of...
