Effect of latitude and mountain height on the timberline (Betula pubescens ssp. czerpanovii) elevation along the central Scandinavian mountain range
Previously published isoline maps of Fennoscandian timberlines show that their highest elevations lie in the high mountain areas in central south Norway and from there the limits decrease in all directions. These maps are assumed to show differences in “climatic forest limits”, but the isoline patterns indicate that factors other than climate may be decisive in most of the areas. Possibly the e...
متن کاملContrasting Effects of Extreme Drought and Snowmelt Patterns on Mountain Plants along an Elevation Gradient
Despite the evidence that increased frequency and magnitude of extreme climate events (ECE) considerably affect plant performance, there is still a lack of knowledge about how these events affect mountain plant biodiversity and mountain ecosystem functioning. Here, we assessed the short-term (one vegetation period) effects of simulated ECEs [extreme drought (DR), advanced and delayed snowmelt (...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

متن کاملDiversity of Plants and Animals in Mountain Ecosystems in Tajikistan
Tajikistan is a hotspot of plant and animal species diversity and endemism andis important for the conservation of biodiversity on a global scale. The country is located ata biological crossroads. Species from Central and Northern Europe, Central Asia, theMiddle East, and North Africa mingle here with endemics found nowhere else. Therichness of Tajikistan‘s biodiversity shows up at the genetic,...
