Аннотация: An introduction is given to the geography of Russian forests and to the specific conditions of the study sites located along the 60degrees latitude east of Moscow (Fyedorovskoe) near the Ural Mountains (Syktivkar) and in Central Siberia near the Yennisei river (Zotino). The climatic conditions were similar at all three sites. The main ecological parameter that changes between European Russia and Siberia is the length of the growing season (230 d above 0 degreesC NE Moscow to 170 d above 0 degreesC in Central Siberia) and to a lesser extent precipitation (580 mm NE Moscow to 530 mm in Central Siberia). The experimental sites were generally similar to the regional conditions,. although the Tver region has less forest and more grassland than the central forest reserve, and the Komi region has slightly less wetland than the study area. The Krasnoyarsk region reaches from the arctic ocean to and central Asia and contains a significant proportion of non-forest land. The boreal forest of west and east Yennisei differs mainly with respect to wetlands, which cover almost half of the land area on the west bank. All sites are prone to disturbance. Heavy winds and drought or surplus water are the main disturbance factors in European Russia (a 15-20 yr cycle), and fire is the dominating disturbance factor in Siberia (220-375 yr for stand replacing fires).

Аннотация: Northern Eurasian ecosystems play an important role in the global climate system. Northern Eurasia (NE) has experienced dramatic climate changes during the last half of the 20th century and to present. To date, how evapotranspiration (ET) and water availability (P-ET, P: precipitation) had changed in response to the climatic change in this region has not been well evaluated. This study uses an improved version of the Terrestrial Ecosystem Model (TEM) that explicitly considers ET from uplands, wetlands, water bodies and snow cover to examine temporal and spatial variations in ET, water availability and river discharge in NE for the period 1948-2009. The average ET over NE increased during the study period at a rate of 0.13 mm year(-1) year(-1). Over this time, water availability augmented in the western part of the region, but decreased in the eastern part. The consideration of snow sublimation substantially improved the ET estimates and highlighted the importance of snow in the hydrometeorology of NE. We also find that the modified TEM estimates of water availability in NE watersheds are in good agreement with corresponding measurements of historical river discharge before 1970. However, a systematic underestimation of river discharge occurs after 1970 indicates that other water sources or dynamics not considered by the model (e.g., melting glaciers, permafrost thawing and fires) may also be important for the hydrology of the region.
