Interactive Effects of Rising Temperature, Elevated CO2 and Herbivory on the Growth and Stoichiometry of a Submerged Macrophyte Vallisneria natans

Global climate changes are affecting organisms and their interactions in terrestrial aquatic ecosystems, such as the increase temperature CO2 concentration. Herbivory interaction is a very important part of nutrient cycle energy flow freshwater ecosystem, may directly or indirectly affect plants, herbivores interactions. In this study, we explored effects rising temperature, elevated concentrations herbivory by an herbivorous snail (Radix auricularia L.) on submerged plant (Vallisneria natans L.). Our results showed that herbivory, had specific growth, statistically there was only one interaction-a reduction leaf number. Under different experimental conditions, always has negative biomass accumulation growth V. natans. Moreover, increases also inhibited its growth. Snail reduced content total carbon nitrogen all treatments, while phenols increased. findings indicate have interactive stoichiometry macrophytes, but further research needed between plants to aid prediction impact change ecosystems.
