Acceleration of cyanobacterial dominance in north temperate‐subarctic lakes during the Anthropocene
Abstract Increases in atmospheric temperature and nutrients from land are thought to be promoting the expansion of harmful cyanobacteria in lakes worldwide, yet to date there has been no quantitative synthesis of long‐term trends. To test whether cyanobacteria have increased in abundance over the pa...
