Building natural classifications for genera with complex morphological variations such as Centaurea needs the support of molecular analysis and knowledge character diversification. Here we use parsimony Bayesian analyses nuclear ribosomal ITS sequences to gain insight into sectional relationships evolution in sections Chartolepis, Cheirolepis, Cynaroides, Grosheimia, Microlophus, Paraphysis, Ph...

Hexane, chloroform, ethyl acetate and ethanolic extracts of the aerial parts of Centaurea austro-anatolica Hub.-Mor. (Asteraceae) were evaluated against microorganisms, including multiresistant bacteria, using a paper disc diffusion method. The chloroform extract exhibited significant antibacterial activity toward all bacteria tested. The chemical composition of the chloroform extract was deter...

" Agapeta zoegana oviposited significantly more on rosette and one-stem plants. " 2 plants had significantly greater A. zoegana larval density than 4 plants. " Significant correlation between the number of larvae infesting plant roots and Centaurea stoebe root diameter. " Cyphocleonus achates fed more frequently on multiple-stem 4 plants. " Arion lusitanicus had a strong feeding preference for ...

We show that the Bayesian star paradox, first proved mathematically by Steel and Matsen for a specific class of prior distributions, occurs in a wider context including less regular, possibly discontinuous, prior distributions.

Centaureaziganensis Yüzb., M. Bona & İ. Genç, a new species is described and illustrated from Gümüşhane province, NE Turkey. The new species grows in rocky places on the south face of Zigana Mountains, and is closely related to Centaureadrabifolioides, from which it differs mainly in stem, achene and phyllary appendage characters. Micromorphological structures of achenes and karyological featur...
