This project aims to advance model predictions to generate novel insights into the triggers of freshwater harmful cyanobacteria blooms. Current models are poorly adapted for this purpose because they fail to account for antecedent environmental forcing. The project is expected to create new knowledge of cyanobacteria dynamics from simulating the adaptive responses of individual cyanobacteria cells, colonies or filaments to temperature, light and nutrient history. Three field studies will be used to validate a new individual based model. The outcomes of this project will be valuable for managing freshwater ecosystems that are increasingly subject to blooms in a warming climate, and for testing suitable mitigation and control strategies.

该项目旨在推进模型预测，以产生新的见解触发淡水有害蓝藻华。目前的模式不能很好地适应这一目的，因为它们没有考虑到之前的环境强迫。该项目预计将创造新的蓝藻动力学知识，从模拟个体蓝藻细胞，菌落或细丝对温度，光和营养历史的适应性反应。三个实地研究将用于验证一个新的基于个人的模型。这个项目的成果对于管理在气候变暖的情况下日益受到水华影响的淡水生态系统，以及测试适当的缓解和控制战略，将是有价值的。
