Unsupervised learning for detection of possible sexual dimorphism in larvae of Belgica antarctica Jacobs (Diptera, Chironomidae)
Belgica antarctica is one of the two native chironomid species of the Antarctic Peninsula. In this species, adult males and females are considerably different, yet the question of larval sex differences in morphometric parameters remains unanswered. In this paper, we analyze five morphometric parame...
