The value of the ITS2 region for the identification of species boundaries between Alloxysta hyperparasitoids (Hymenoptera: Charipidae) of aphids

open access: yesEuropean Journal of Entomology, 2003
1) Alloxystinae are major secondary parasitoids of aphids, important in both their ecology and pest management. 2) Two radically differing views of alloxystine taxonomy exist in the literature, in one of which the group is very diverse, in the other it ...

First DNA analysis of pill scarabs (Coleoptera: Hybosoridae: Ceratocanthinae) reveals multiple paraphyly of Afrotropical Philharmostes

open access: yesEuropean Journal of Entomology, 2019
This paper is the first attempt to resolve relationships among the Ceratocanthinae: Ceratocanthini pill scarab beetles using DNA sequences. It is focused on the Philharmostes group of seven Afrotropical genera: Baloghianestes (3 spp.), Callophilharmostes

Ancient DNA from coral-hosted Symbiodinium reveal a static mutualism over the last 172 years. [PDF]

open access: yes, 2013
Ancient DNA (aDNA) provides powerful evidence for detecting the genetic basis for adaptation to environmental change in many taxa. Among the greatest of changes in our biosphere within the last century is rapid anthropogenic ocean warming.

ITS2 data corroborate a monophyletic chlorophycean DO-group (Sphaeropleales) [PDF]

open access: yesBMC Evolutionary Biology, 2008
Abstract Background Within Chlorophyceae the ITS2 secondary structure shows an unbranched helix I, except for the 'Hydrodictyon' and the 'Scenedesmus' clade having a ramified first helix. The latter two are classified within the Sphaeropleales, characterised by directly opposed basal bodies in their flagellar ...
