Interactions of plants with arbuscular mycorrhizal fungi (AMF) may range along a broad continuum from strong mutualism to parasitism, with mycorrhizal benefits received by the plant being determined by climatic and edaphic conditions affecting the balance between carbon costs vs. nutritional benefits. Thus, environmental conditions promoting either parasitism or mutualism can influence the mycorrhizal growth dependency (MGD) of a plant and in consequence may play an important role in plant-plant interactions.

Adaptive traits ensuring efficient nutrient acquisition, such as extensive fine root systems, are crucial for establishment of pioneer plants on bare sand. Some successful pioneer species of temperate, European sand ecosystems are characterised as obligate mycorrhizals, thus likely substituting fine roots with arbuscular mycorrhizal fungi (AMF). However, it is not clear whether AM fungal-mediated acquisition of scarce and immobile nutrients such as phosphorus (P) is an advantageous strategy on bare sand over foraging via roots.
