Belowground carbon allocation, effects of temperature and soil moisture.

Updated 2003-04-24

Carbon allocation to, and translocation in-between, different below-ground compartments in wet and semi wet mire ecosystems are to be studied during summer 2002. The project is part of EU founded CARBOMONT, where carbon cycling in European alpine regions is studied. Stordalen mireConsidered methods were applied to dry heath ecosystems summer 2001, which successfully produced a budget over carbon allocation to belowground compartments in heath ecosystems. This year’s study is focused on wet and semi wet ecosystems, making it possible to compare below-ground carbon allocation and translocation in different ecosystems dominating Stordalen mire. Stordalen birch forest Carbon allocation to Ericoid mycorrhizae was studied under enhanced precipitation conditions, which resulted in an altered carbon allocation pattern compared to untreated ecosystems. This summer the effects of increased temperature on carbon allocation to Ericoid mycorrhizal compartments are to be studied. Temperature effects on mycorrhizal functions such as 15N labelled amino acid uptake, will also be investigated.
