  • Climate aridization and increased anthropogenic pressure pose a severe threat to natural vegetation, including coastal plant communities. Those located in river basins of the desert zone of Central Asia are among the most vulnerable. Of the variety of ecosystems of the Ili-Balkhash region of Kazakhstan, forests dominated by a rare relict species Populus pruinosa Schrenk are of particular concern. This species occupies a very narrow ecological niche associated with river banks of the arid zone, which makes it very vulnerable to adverse natural and anthropogenic factors.

  • Turkey is one of the most important temperate countries on Earth in terms of plant diversity. There is a growing interest in understanding habitat suitability and future distributions of species in the scientific world. Because climate change has impacted ecosystems with major consequences, species are shifting and declining much faster than in the past. Some global climate models used for predicting climate in the future better represent and have higher reliability for some climate types. Ferulago glareosa, which lives in Turkey, is a rare endemic plant species.

  • The biology and ecology of Orchis galilaea Schltr., a species endemic to Lebanon, Palestine, and Jordan, is poorly studied, a fact that hinders present and future management and conservation efforts concerning this species. In this paper, we report findings of a field investigation that assessed the impact of altitude, population density, and plant size on the reproductive success of O. galilaea.

  • Oxytropis glandulosa Turcz. (Fabaceae) is a rare perennial plant endemic to Buryatia (Russia). We sequenced three intergenic spacers (the psbA–trnH, trnL–trnF, and trnS–trnG) of chloroplast DNA (cpDNA) in specimens of four populations from two geographic regions (Barguzin and Yeravna depressions) within this species range.
