Abstract

Increasing atmospheric nitrogen deposition and changing precipitation pattern due to anthropogenic activities can affect nutrient cycling of the plant-soil system. This study focused on the effects of simulative increases in nitrogen and precipitation on foliar N and P concentrations, resorption efficiency and proficiency in five dominant desert ephemeral species. Foliar nutrient concentration and resorption efficiency differed significantly among species. The averaged leaf nitrogen and phosphorus concentrations across five desert ephemeral plants were 30.1 mg·g-1 and 3.6 mg·g-1 respectively, and the N:P ratio ranged from 6.8 to 10.5. The average leaf nitrogen resorption efficiency (NRE, 34.08%) was lower than the phosphorus resorption efficiency (PRE, 73.03%); N addition had no significant effects on PRE and NRE; N addition reduced the nitrogen resorption proficiency (NRP) of Erodium oxyrrhynchum, Alyssum linifolium and Malcolmia scorpioides, increased the NRP of Leptaleum filifolium and Schismus arabicus, but had little effect on the phosphorus resorption proficiency (PRP). Different levels of N addition had significant effects on PRE rather than NRE; Meanwhile, Water addition significantly increased NRE (except for L. filifolium), but had no effects on PRE, NRP and PRP, yet the PRE (except for E. oxyrrhynchum) and NRP increased as well, the PRP changed little; N significantly interacted with water to affect PRE but did not affect NRE, and the changes of PRE were different among species. These results suggest that increased nitrogen input and precipitation can significantly affect the nutrition status and resorption processes of desert ephemeral plants, which will have an important effect on species composition of the ephemeral plant community and nutrient cycling of the desert ecosystem.
