چکیده
Woody vegetation growth conditions have marked effects on hemicellulose, cellulose and lignin formation. In this study, the climatic responses of these major cell wall polymers in Betula tortuosa Ledeb. were analyzed. 35 annual rings (1980–2015) trees growing alpine forest-tundra Kuznetsk Ala Tau studied using Fourier-transform infrared (FTIR) spectroscopy pyrolysis–gas chromatography–mass spectrometry (Py–GC/MS). Analysis correlation resulting spectra Py–GC/MS values with mean air temperature precipitation showed that polymeric composition was mainly determined by June–August climate. The factor limiting development “unique” polymer found a deficit heat. At end season, had largely negative impact formation walls. authors believe combining FTIR is an effective approach to quantifying consequences current climate trends for Siberian forest ecosystems.

Seasonal changes in an alpine soil bacterial community in the colorado rocky mountains.
The period when the snowpack melts in late spring is a dynamic time for alpine ecosystems. The large winter microbial community begins to turn over rapidly, releasing nutrients to plants. Past studies have shown that the soil microbial community in alpine dry meadows of the Colorado Rocky Mountains changes in biomass, function, broad-level structure, and fungal diversity between winter and earl...

Analysis of inter-decade changes in trends and spatial patterns of annual and seasonal precipitation, case study: West of Iran
The present research about the spatial changes of precipitation is mainly focused on western areas of Iran. Precipitation data for three seasons of fall, winter, and spring have been obtained from Esafzari Database, with 15*15 km spatial resolution in the form of a Lambert Cone Image System for the period from 1986 to 2015. To examine the prevailing pattern of precipitation in west of Iran, we ...
