Variation in resource allocation strategies and environmental driving factors for different life‐forms of aquatic plants in cold temperate zones

Resource allocation, including biomass allocation and nutrient between different organs in a plant, reflects the trade-off partitioning above-ground below-ground growth adaptation strategies of plants changing environment. Although varied resource patterns among functional groups terrestrial have been found, few studies focused on freshwater ecosystems. In this study, to clarify their responses environmental factors, we collected analysed 2,162 samples from 262 aquatic plant communities (including emergent plants, floating-leaved submerged plants) various habitats north-eastern China. The results showed that root/shoot (R/S) ratios three life-forms were significantly different, trend ratio values for occurred following order: > plants. There obvious scaling relationships biomass, N (or P or N:P ratios) ratios), but exponents changed life-forms. nutrients organ factors was not consistent partial least squares path model revealed stoichiometric characteristics are important direct drivers production.

Our study demonstrates global climate change may nutrients, influence growth, further altering community structure biogeochemical cycles.
