  Keywords: Tulipa; comparative morphology; morphology based phylogeny; cladistic analysis

  Abstract The Tian Shan and Pamir-Alay mountains of Central Asia are generally regarded as the primary center of diversity of Tulipa species, but a comparative morphological description of Central Asian Tulipa species is still lacking. To fill the existing gap, we studied 48 Tulipa species found in Central…

  Keywords: biodiversity; conservation strategy; restoration; threatened species

  Abstract Continuing wide-scale habitat degradation and species extinctions indicate that existing plant conservation practices are inadequate and new approaches are needed. I briefly summarize the major principles of a previously proposed concept called conservation- oriented restoration and compare it…
