Insects are the most speciose group of animals, but the phylogenetic relationships of many major lineages remain unresolved. We inferred the phylogeny of insects from 1478 protein-coding genes. Phylogenomic analyses of nucleotide and amino acid sequences, with site-specific nucleotide or domain-specific amino acid substitution models, produced statistically(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)
Island radiations have played a major role in shaping our current understanding of allopatric, sympatric and parapatric speciation. However, the fact that species divergence correlates with island size emphasizes the importance of geographic isolation (allopatry) in speciation. Based on molecular and morphological data, we investigated the diversification(More)
The amplified fragment length polymorphisms (AFLP) method has become an attractive tool in phylogenetics due to the ease with which large numbers of characters can be generated. In contrast to sequence-based phylogenetic approaches, AFLP data consist of anonymous multilocus markers. However, potential artificial amplifications or amplification failures of(More)
Several pitfalls can mislead phylogenetic analyses based on molecular data, including heterogeneous base composition. Previous work has revealed conflicting topologies in analyses of the land snail genus Theba Risso 1826 based on mitochondrial cytochrome oxidase subunit I (COI) and nuclear AFLP data, respectively. However, the third codon positions of COI(More)
