Figure 1From: Strategies for monitoring and managing mass populations of toxic cyanobacteria in recreational waters: a multi-interdisciplinary approachGAM for predicting the biovolume of toxic cyanobacteria in UK lakes. The response of log cyanobacterial biovolume to log alkalinity and log colour respectively with dashed lines to indicate ±2 standard errors, edf indicates the estimated degrees of freedom used to fit each variable.Back to article page
