The resolving power and statistical support provided by two protein-coding (RPB1 and RPB2) and three ribosomal RNA-coding (nucSSU, nucLSU, and mitSSU) genes individually and in various combinations were investigated based on maximum likelihood bootstrap analyses on lichen-forming fungi from the class Lecanoromycetes (Ascomycota). Our results indicate that the optimal loci (single and combined) ...
Recent DNA-based phylogenetic analyses of the family Thamnophilidae have shown that the genus Myrmotherula is polyphyletic. Traditional plumage-based taxonomy has been misleading in terms of identifying independently evolving lineages within the complex. Here, we integrate a molecular phylogeny with morphometric information and ancestral reconstruction of syringeal character states of the Muscu...
Biological invasions are a major conservation threat for biodiversity worldwide. Islands are particularly vulnerable to invasive species, especially Mediterranean islands which have suffered human pressure since ancient times. In the Balearic archipelago, reptiles represent an outstanding case with more alien than native species. Moreover, in the last decade a new wave of alien snakes landed in...

Introduction
 Poplars and aspens (Populus sp.) are common in forest stands, shelterbelts, rural landscaping, special plantations as short-rotation woody crops; they promising tree species for biofuel bioenergy production. Wood-boring insects browse galleries a stem or branches that interrupt sap circulation promote infestation by plant pathogens. Some of these can additionally weaken trees...
