Sammanfattning
Tannins in forest soils bind organic nitrogen into persistent complexes, impacting nutrient cycling and ecosystem productivity. Mycorrhizal fungi, especially ectomycorrhizal (EcM) and ericoid types, can degrade these complexes, releasing nitrogen for plant uptake and influencing community composition. Arbuscular mycorrhizal (AM) fungi may also assist in nitrogen acquisition via interactions with free-living bacteria. Understanding these fungal-tannin interactions reveals key mechanisms controlling nitrogen cycling (N cycling) in forest ecosystems, especially in tannin-rich temperate and boreal regions. We propose a conceptual framework to explore the feedback loops between plant chemistry, soil microbes, and ecosystem processes. Such knowledge is vital for predicting how forest communities will respond to climate change, land use, and invasive species, informing sustainable forest management strategies.
