Numerical analysis of Saxifraga in Iran was carried out on the basis of morphological and chorological data. The cluster analysis confirmed that the genus in Iran includes two distinct groups: Group one consists of two subgroups, a) alpine Irano-Turanian endemic species (S. ramsarica, S. iranica, S. wendelboi, S. koelzii), and b) Euxino-Hyrcanian species (S. paniculata subsp. Cartilaginea, S. k...

Research Highlights: Fine roots play an important role in plant growth as well carbon (C) and nutrient cycling terrestrial ecosystems. Gaining a wider knowledge of their dynamics under forest gap opening would improve our understanding soil input below-ground stock accumulation. Single-tree selection is increasingly recognized alternative regime cutting sustaining biodiversity stock, along with...

the Quaternary climatic oscillations and persist today in isolated refugial areas is crucial for maintaining the global diversity of plants, especially considering the current climate trend of increasing temperatures and water stress ( Petit et al., 2005 ; Kozlowski et al., 2012 ). The Arcto-Tertiary relict fl ora, that covered large parts of the northern hemisphere during the Eocene but since ...
