Using a five-gene phylogeny to test morphology-based hypotheses of Smittium and allies, endosymbiotic gut fungi (Harpellales) associated wit...
Smittium, one of the first described genera of gut fungi, is part of a larger group of endosymbiotic microorganisms (Harpellales) that live predominantly in the digestive tracts of aquatic insects. As a diverse and species-rich taxon, Smittium has helped to advance our understanding of the gut fungi...

Phylogeny of Tunicata inferred from molecular and morphological characters
I (cox1) and 18S rDNA sequences were obtained for 14 and 4 tunicate species, respectively. 18S rDNA sequences were aligned with gene sequences obtained from GenBank of 57 tunicates, a cephalochordate, and a selachian craniate. Cox1 sequences were aligned with the sequence of two ascidians and a ceph...
ITS2 rRNA evolution and its congruence with the phylogeny of muricid neogastropods (Caenogastropoda, Muricoidea)
Molecular phylogenies support multiple morphological reductions in the liverwort subclass Marchantiidae (Bryophyta)
The phylogeny of one of the putative basal-most group of land plants, the Marchantiidae, is estimated with morphological characters and with sequences of the nuclear (LSU) rDNA gene (first four domains of the 5′ end of the 26S rRNA and four subsequent regions) from 34 species and 27 genera. Molecul...
Cloning and sequencing of wsp encoding gene fragments reveals a diversity of co-infecting Wolbachia strains in Acromyrmex leafcutter ants
We detected an unusually high diversity of nine Wolbachia strains in queens of three species of leafcutter ants. Up to four strains co-occurred in a single ant. Most strains occurred in two clusters (InvA and InvB), but the social parasite Acromyrmex insinuator hosted two additional infections. The...
Phylogeography of the Eurasian Willow Tit (Parus montanus) based on DNA sequences of the mitochondrial cytochrome b gene
Our data suggest that the mono-frequency song type may be ancestral and was retained over a long evolutionary time in certain populations, but was altered or camouflaged by learning processes in others....
Molecular phylogenetic analysis of Fringillidae, “New World nine-primaried oscines” (Aves: Passeriformes)
We present phylogenetic hypotheses of 44 fringillids that represent the overall diversity of the family, based on 3.2kb of mitochondrial DNA sequences, and phylogenetic analyses for a subset of fringillids based on new and published mitochondrial cytochrome b sequences. Monophyly of Fringillidae and...
Molecular phylogeny of the Eichhorni group of Delias Hu¨bner, 1819 (Lepidoptera: Pieridae)
I and II. Moreover, they also indicate that the initial diversification of the eichhorni group involved separation of the D. catisa+D. toxopei clade, followed by the divergence of other species including the eichhorni complex. Based on these findings, it is supposed that this group first appeared cl...
The evolutionary history of maternal plant-manipulation and larval feeding behaviours in attelabid weevils (Coleoptera; Curculionoidea).
I genes. Our analyses indicated that the attelabid weevils form a monophyletic group, and that maternal plant-cutting behaviour originated in a common ancestor of Attelabidae, but was subsequently lost in several lineages. Monophyly of the subfamily Attelabinae was also recovered with high support,...
