| Research Abstract |
Comparative study was carried out for evaluation of future vegetation change in central Siberia, Russia, For this study, we selected typical forests on north- and south-facing slopes as present and future conditions, respectively in central Siberia. Vegetation there was clearly changed along micro-climatic conditions. Maximum photosynthetic rate of trees grown under the north-facing slope was slightly lower than that under the southfacing slope. Light acclimation was found in the composition of Chl. a/b. Shrubs showed relatively high photosynthetic rate under light saturation. Based on former and present results, we may conclude photosynthetic decline would be closely related to foliar aging which is affected by photosynthetic responses to light environments of the slopes. In conclusion, we may infer the plausible vegetation change in future based on field and lob. Studies.
