On the evolution of shape and size divergence in Nebria (Nebriola) ground beetles (Coleoptera, Carabidae)

摘要: Ground beetles include many species of rather recent evolutionary origin that are extremely similar in their external morphology. We used geometric morphometrics to quantify the relative degree morphological divergence three closely related polytypic alpine genus Nebria, subgenus Nebriola (Nebria cordicollis, N. laticollis and fontinalis). To examine patterns, we adopted a hierarchical design, using both shape size discriminate between species, subspecies within populations subspecies. A semilandmark-based approach was describe pronotum, elytron median lobe aedeagus. The diverged significantly size. There were clear interspecific differences traits (elytron pronotum) Furthermore, also body size, (evaluated by computation static allometries). Shape...
