Dynamic Changes in Plant Resource Use Efficiencies and Their Primary Influence Mechanisms in a Typical Desert Shrub Community

Understanding plant resource use efficiencies (<i<RUE</i<s) and their tradeoffs in a desert shrub community, particularly as it concerns the usage of water, light, and nitrogen, remains an ecological imperative. Plant <i<RUE</i<s have been widely used as indicators to underst...

Plant <i<RUE</i<s have been widely used as indicators to understand plant acclimation processes to unfavorable environmental conditions. This study aimed to examine seasonal dynamics in <i<RUE</i<s in two widely distributed plant species in a typical desert shrub community (i.e., <i<Artemisia ordosica</i< and <i<Leymus secalinus</i<) based on in-situ measurements of leaf photosynthesis, specific leaf area (<i<SLA</i<), leaf nitrogen concentration (i.e., <i<N</i<<sub<mass</sub< + <i<N</i<<sub<area</sub<), and several site-related abiotic factors. Both species exhibited significant seasonal variation in <i<RUE</i<s, with a coefficient of variation (CV) <30% and seasonal divergence among the various <i<RUE</i<s. Seasonal divergence was largely controlled by variation in stomatal conductance (<i<G</i<s), which was in turn influenced by variation in soil water content (<i<SWC</i<) and water vapor pressure deficit (<i<VPD</i<). <i<RUE</i<s between species converged, being positively correlated, yielding: (i) <i<r</i<<sup<2</sup< = 0.40 and <i<p</i< < 0.01 for <i<WUE;</i< (ii) <i<r</i<<sup<2</sup< = 0.18 and <i<p</i< < 0.01 for <i<LUE</i<; and (iii) <i<r</i<<sup<2</sup< = 0.25 and <i<p</i< < 0.01 for <i<NUE</i<. <i<RUE</i<s for <i<A. ordosica</i< were mostly larger than those for <i<L. secalinus</i<, but less reactive to drought. This suggests <i<A. ordosica</i< was more conservative in its usage of available resources and was, therefore, better able to adapt to arid conditions. Resource use strategies between species differed in response to drought. Desert shrubs are projected to eventually replace grasses, as drought severity and duration increase with sustained regional climate change.

This study aimed to examine seasonal dynamics in <i<RUE</i<s in two widely distributed plant species in a typical desert shrub community (i.e., <i<Artemisia ordosica</i< and <i<Leymus secalinus</i<) based on in-situ measurements of leaf photosynthesis, specific leaf area (<i<SLA</i<), leaf nitrogen concentration (i.e., <i<N</i<<sub<mass</sub< + <i<N</i<<sub<area</sub<), and several site-related abiotic factors.

abstract	Understanding plant resource use efficiencies (<i<RUE</i<s) and their tradeoffs in a desert shrub community, particularly as it concerns the usage of water, light, and nitrogen, remains an ecological imperative. Plant <i<RUE</i<s have been widely used as indicators to understand plant acclimation processes to unfavorable environmental conditions. This study aimed to examine seasonal dynamics in <i<RUE</i<s in two widely distributed plant species in a typical desert shrub community (i.e., <i<Artemisia ordosica</i< and <i<Leymus secalinus</i<) based on in-situ measurements of leaf photosynthesis, specific leaf area (<i<SLA</i<), leaf nitrogen concentration (i.e., <i<N</i<<sub<mass</sub< + <i<N</i<<sub<area</sub<), and several site-related abiotic factors. Both species exhibited significant seasonal variation in <i<RUE</i<s, with a coefficient of variation (CV) <30% and seasonal divergence among the various <i<RUE</i<s. Seasonal divergence was largely controlled by variation in stomatal conductance (<i<G</i<s), which was in turn influenced by variation in soil water content (<i<SWC</i<) and water vapor pressure deficit (<i<VPD</i<). <i<RUE</i<s between species converged, being positively correlated, yielding: (i) <i<r</i<<sup<2</sup< = 0.40 and <i<p</i< < 0.01 for <i<WUE;</i< (ii) <i<r</i<<sup<2</sup< = 0.18 and <i<p</i< < 0.01 for <i<LUE</i<; and (iii) <i<r</i<<sup<2</sup< = 0.25 and <i<p</i< < 0.01 for <i<NUE</i<. <i<RUE</i<s for <i<A. ordosica</i< were mostly larger than those for <i<L. secalinus</i<, but less reactive to drought. This suggests <i<A. ordosica</i< was more conservative in its usage of available resources and was, therefore, better able to adapt to arid conditions. Resource use strategies between species differed in response to drought. Desert shrubs are projected to eventually replace grasses, as drought severity and duration increase with sustained regional climate change.
