Although phylogenetic studies are increasingly utilizing multi-locus datasets, a review of GenBank data for the Gastropoda indicates a strong bias towards a few short gene fragments (most commonly COI, LSU rRNA, and SSU rRNA). This is particularly the case for the Rissooidea, one of the largest and most taxonomically difficult gastropod superfamilies. Here(More)
We present the first study of the warbler family Acrocephalidae based on one mitochondrial and three nuclear DNA loci, in total approximately 2900 bp, including most or all of the species in three (Acrocephalus, Hippolais and Chloropeta) of the four genera and one species in the fourth genus (Nesillas) in this family. All three genera were suggested to be(More)
BACKGROUND AND AIMS Treatment with GH in short children has focused on height development. Little is known about the concomitant changes in muscle mass, bone structure and bone strength. METHODS Muscle area as well as parameters of bone architecture (bone mineral content, BMC; volumetric cortical density, total bone area, TBA; cortical area, cortical(More)
The invasive land snail Theba pisana pisana has been widely dispersed through human activities. The Mediterranean and adjacent Atlantic coasts are considered as natural range of this species, which also occurs northwards to the Netherlands, the British Islands and in Ireland. In addition, T. p. pisana has been introduced to some Macaronesian Islands as well(More)
Condensing the information of a total of 1551 to 469 influenza A H1N1 isolates we investigated the frequency of host shifts among bird, human and swine. Phylogenies of hemagglutinin and neuraminidase as well as ancestral host reconstructions were simultaneously inferred in a Bayesian framework. The surface proteins had to be analyzed separately because of(More)
Genetic distances are increasingly being used for identification and species delimitation, especially since the introduction of "barcoding". While for phylogenetic inferences great care is generally taken to choose the best-fit evolutionary model, this is usually neglected in calculating genetic distances. Moreover, distances obtained from others than(More)
The circumscription of the avian superfamily Sylvioidea is a matter of long ongoing debate. While the overall inclusiveness has now been mostly agreed on and 20 families recognised, the phylogenetic relationships among the families are largely unknown. We here present a phylogenetic hypothesis for Sylvioidea based on one mitochondrial and six nuclear(More)
Recurrent outbreaks of H5N1 HPAIV occurred in several Central European countries in 2007. In-depth phylogenetic analyses which included full-length genomic sequences of the viruses involved were performed to elucidate possible origins of incursions and transmission pathways. Tree reconstructions as well as host-shift and ancestral area inferences were(More)
Among oceanic islands, the Canary Islands offer exceptional opportunities for studying speciation processes due to their habitat diversity and well documented geological history. Based on a combined COI+ITS1 data set for more than 140 specimens, we studied the diversification of the land snail genus Theba on the Canary Islands and adjacent African and(More)
