N:P Ratio and the Nature of Nutrient Limitation in Calluna-Dominated Heathlands There is growing evidence from different sources that prolonged high N deposition causes a shift from nitrogen (N.) limitation to nitrogen and phosphorus (... GV Oheimb,SA Power,K Falk,... - 《Ecosystems》 被引...
Other sources were the stocked animals, precipitation, and the initial water used. The N output sources in the different culture systems were the stocked animals, sediment accumulation, water accumulation, and absorption and volatilization by the enclosure cloth, which accounted for 62.80%–77.15%, ...

During evolution, mycorrhizal fungi have refined their biotrophic capabilities to take advantage of their hosts as food sources and protective niches, while plants have developed multiple strategies to accommodate diverse fungal symbionts. Intimate associations with pervasive ecological success have originated ...
