TL;DR: In this article, the authors used 867 vegetation samples above the treeline from 60 summit sites in all major European mountain systems to show that ongoing climate change gradually transforms mountain plant communities.

TL;DR: Recent changes in vascular plant species richness observed in a standardized monitoring network across Europe’s major mountain ranges are presented and indicate that high-altitude species, and in particular the rich endemic alpine flora of many Mediterranean mountain ranges, will come under increasing pressure in the predicted warmer and drier climates in this region.

TL;DR: In this article, the authors present recent (2001 to 2008) changes in vascular plant species richness observed in a standardized monitoring network across Europe's major mountain ranges, showing that European mountaintop flower species richness is increasing on northern summits but decreasing on southern summits.

TL;DR: In this article, the authors assess the impacts of climate change on 2632 plant species across all major European mountain ranges, using high-resolution (ca. 100 m) species samples and data expressing four future climate scenarios.

TL;DR: Of the two elicitors, SA was more effective in stimulating the accumulation of hypericins and pseudohypericin in shoot cultures of Hypericum hirsutum and H. maculatum, and it is suggested that culture of shoots on MS medium supplemented with BA or Kin enhanced production ofhypericins in H. Maculatum and hyperforin inH.
