Perspectives on Odonata
ثبت نشده
چکیده
This thesis considers the phylogeny of Odonata from two different viewpoints. The first article, “The Palaeoptera Problem”, is an attempt at placing Odonata in the pterygote insect phylogenetic tree. The second, “A phylogenetic perspective on larval spine morphology in Leucorrhinia (Odonata, Libellulidae)”, is an in-depth view of the whiteface dragonflies, a monophyletic group that only contains 14-15 species.
