Streams are sensitive sentinels for environmental change by their integration of processes in terrestrial and aquatic systems. Upland headwater streams in the north Swedish tundra show seasonally exceptional high concentrations of uncolored dissolved organic carbon (DOC) and high carbon dioxide concentrations.
Tundra P - Phosphorus transformation across Pan-Arctic tundra ecosystems
Phosphorus (P) constrains the activity of plants and decomposers, and therefore carbon storage in many arctic ecosystems, yet our understanding of P availability in the tundra lags behind understanding of the carbon and nitrogen cycles.
Phosphorus efficient agriculture with arbuscular mycorrhizal fungi
Phosphorus (P) is an essential element for all living organisms, and without P we cannot produce food. Most P that is used in agriculture comes from mines in Northern Africa, which are about to be depleted.
Nutrient availability along two arctic successional gradients
Understanding how plant succession is influenced by climate warming is a key issue for understanding how arctic landscapes will change in the future. At high latitudes, low temperature drives disturbance and the consequent primary succession (e.g., cryoturbation, glacier advance and retreat).
