Due to the deep valleys, steep mountains and influence of Indian monsoon on Mainri Mountains (Yunnan Province, China), it is difficult estimate glacier change from microwave optical remote sensing. To bridge gap between low-quality space-borne sensing scarce in situ measurements, airborne sensing, such as unmanned aerial vehicles (UAVs), may provide a remarkable opportunity monitor with high-qu...

Cousinia glochidiata (Sect. Pseudactinia) and C. albiflora (Bornm. & Sint.) Bornm. (Sect. Stenocephalae), two narrow endemics to Kopetdagh mountains, are newly recorded for the flora of Iran from Razavi and North Khorassan provinces near the borders of Turkmenistan. The presence of C. apiculata Tscherneva in Iran is confirmed. New localities and additional notes on the distribution and conserva...

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

It has been known for over a century that the Uinta Mountains contained numerous alpine glaciers during parts of the Quaternary Period, yet until recently, the glacial record on the south side of the range had received little scientifi c attention. Results of recent 1:24,000-scale fi eld mapping of surfi cial deposits in the southern Uinta Mountains indicate that glaciers in the southwestern an...

Zapadnyy Bulganak, Alma, Kacha, Belbek, Chernaya rivers belong to the of north-western slope Crimean Mountains. The sources are located on slopes Main Ridge Mountains, then flow from east west almost parallel each other. Up about middle their course, they have a character typical mountain streams (except for Bulganak River). river valleys in upper reaches V-shaped, narrow, dissected by numerous...

Mountains of Anatolia are one of the main Mediterranean biodiversity hotspots and their richness in endemic species amounts for 30% of the flora. Two main factors may account for this high diversity: the complex orography and its role as refugia during past glaciations. We have investigated seven narrow endemics of Centaurea subsection Phalolepis from Anatolia by means of microsatellites and ec...

Imagine a world without mountains! Temperature, wind and rainfall patterns would differ greatly from what we know. In Asia, the very high Tibetan Plateau exerts a strong influence on climate. Heated directly by intense solar radiation during summertime, the temperatures in June– August form a regional maximum. Lhasa at 3.65 km above sea level, for example, has an average comfortable 15°C during...

During the last century, the socio-economic conditions of European mountain areas have completely changed, particularly in locations far from industrial areas. As a consequence of the migration of workers towards densely inhabited valleys and close-to-mountains lowland areas offering better income opportunities, the population of many small mountain villages has been declining and ageing. The t...
