Panayiotis Trigas

TL;DR: A revised description of the species is provided and its taxonomic position is re-evaluate, proposing to treat the taxon guicciardii at the subspecific rank of S. marschallii.

TL;DR: In this paper , the authors investigate how climate and land-cover change may alter the distribution of four single mountain endemics and three very rare Peloponnesian endemic taxa of the National Park via a species distribution modelling approach, and estimate the current and future extinction risk of the aforementioned taxa based on the IUCN Criteria A and B, in order to investigate the need for designing an effective plant micro-reserve network and to support decision making on spatial planning efforts and conservation research for a sustainable, integrated management.

TL;DR: In this article , nine Hypericum species were studied for their antimicrobial activity and their total phenolic and flavonoid content, and the highest phenolic content was found in Hypericum perforatum extract (86 ± 12.90 mg GAE/g dry plant material).

TL;DR: The analyses showed that all currently known species from Greece (P. graminea, P. phthiotica and P. saxifraga) represent distinct taxonomic entities, and two recently collected populations from SE Peloponnisos represent a fifth Petrorhagia species, which is first described and illustrated here as P. laconica.

TL;DR: Allium stamatiadae from Andros island (Cyclades, Aegean archipelago, Greece) is described and illustrated and its closest relatives are A. orestis and A. dirphianum.
