We investigated effects of defoliation by gypsy moth (Lymantriadispar L.) larvae on plant fitness and on foliar nutrient dynamics in scrub oak (Quercusilicifolia Wangenh.). Complete defoliation of treatment plants in 1986 and 1987 resulted in the production of a second flush of leaves (secondary leaves) in each of those years. Insecticide effectively protected controls from herbivory. Mean radial stem growth in 1987–1988 and acorn production in 1988–1989 in plants defoliated by L. dispar were 49% and 88% less than in controls, respectively. Defoliation had little effect on the content of nitrogen, phosphorus, copper, manganese, and zinc in green leaves. However, there was significantly less nitrogen, copper, and zinc in senesced secondary leaves of treatment plants than in the primary leaves of controls. Reduced levels of copper and zinc were also evident in senesced primary leaves of defoliated plants in 1988, when no defoliation occurred. Resorption efficiencies for copper and zinc averaged, respectively, 29% and 117% higher in defoliated plants than in controls for all three years, supporting the hypothesis that resorption may be plastic in response to changes in the magnitude of internal nutrient pools. The lack of such a response in resorption of nitrogen and phosphorus may have been due to biochemical and (or) physiological limitations that prevented increased resorption, since resorption efficiencies of these elements were already high (72% and 75%, respectively).

Abstract Background Soil salinity is a major abiotic constraint to plant growth and development in the arid and semi-arid regions of the world. However, the influence of soil salinity on the process of nutrient resorption is not well known. We measured the pools of both mature and senesced leaf nitrogen (N), phosphorus (P), potassium (K), and sodium (Na) of desert plants from two types of habitats with contrasting degrees of soil salinity in a hyper-arid environment of northwest China. Results N, P, K revealed strict resorption, whereas Na accumulated in senesced leaves. The resorption efficiencies of N, P, and K were positively correlated with each other but not with Na accumulation. The degree of leaf succulence drives both intra-and interspecific variation in leaf Na concentration rather than soil salinity. Both community- and species-level leaf nutrient resorption efficiencies (N, P, K) did not differ between the different habitats, suggesting that soil salinity played a weak role in influencing foliar nutrients resorption. Conclusions Our results suggest that plants in hyper-arid saline environments exhibit strict salt ion regulation strategies to cope with drought and ion toxicity and meanwhile ensure the process of nutrient resorption is not affected by salinity.
