Potential absorption distance for Rb+ by Stipa purpurea and Leontopodium nanum in an alpine steppe

doi:10.7523/j.ucas.2020.0039

Abstract

Abstract: Micro-patches are basic spatial units of steppe vegetation, which cause redistribution of soil nutrients during the formation and break of the patches. To what extent the resources in inter-patch bare ground could be utilized by plants is of an important issue to be answered. In this study, we injected rare elemental tracer Rb⁺ into the soil at different distances from the vegetation patch. By measuring the amount and distance of Rb⁺ being absorbed by vegetation micro-patches, we found that:1) the average potential absorption distance of Rb⁺ by the dominant species Stipa purpurea is 5.6 cm, which almost equals the average interval of 5.7 cm among patches; 2) the average potential absorption distance by companion species Leontopodium nanum is 34.2 cm, which is much larger than that of S. purpurea and average interval among patches; 3) the total amount of Rb⁺ absorption is significantly positively correlated (P<0.001) with the biomass/size of the micro-patches in both species. These results indicate that the nutrient resources in the bare soil are accessible to adjacent plant patches and that large patches have higher utilization potential and broader foraging area than small ones.

Key words: vegetation micro-patches, absorption distance, Rb⁺ tracer, Stipa purpurea, Leontopodium nanum
