Relationships between allometric patterns of the submerged macrophyte Vallisneria natans, its stoichiometric characteristics, and the water exchange rate

Hydrological variation is well-known to affect the morphological plasticity of aquatic macrophytes; however, whether these responses are size-dependent (“apparent plasticity”) or not (“real plasticity”) remains unclear, particularly with respect to the water exchange rate (WER). Here, we used allome...
