Members of several genera of Asteraceae, belonging to the tribes Mutisieae, Cardueae, Lactuceae (all subfamily Cichorioideae), and of Astereae, Senecioneae, Helenieae and Heliantheae (all subfamily Asteroideae) have been analyzed for chemodiversity of their exudate flavonoid profiles. The majority of structures found were flavones and flavonols, sometimes with 6- and/or 8-substitution, and with...

High-resolution pollen analysis of a sediment core recovered from Paliouras lagoon (Greece) allowed us to reconstruct the environmental dynamics Halkidiki peninsula during last 4000 years. Palynological results have been interpreted and compared with detailed historical data, showing distinct phases human-landscape interactions Bronze Age until recent times. Pollen spectra revealed an environme...

A new genus, Caucasoseris, is established to accommodate Prenanthes abietina, a species of hitherto uncertain systematic position distributed in the western Caucasus and northeasternmost Turkey montane conifer mixed forests. Agreement has existed that belongs somewhere Crepidinae or Lactucinae but its morphological features do not match any genus previous molecular phylogenetic analyses could e...

To study synanthropic plants (weeds), weeds need to be separated from non-weeds, a difficult task due the existing gradient in nature. A representative family of Mexican flora (Asteraceae) and state very rich species (Michoacán) are used as model for this additional analyses. total 357 listed based on critical review specimens bibliographic information, well defined criteria. In addition, tribe...
