Intra‐strain Variability in the Effects of Temperature on UV‐B Sensitivity of Cyanobacteria
Abstract Stratospheric ozone depletion is mostly marked over the Antarctic and to a lesser extent over the Arctic, though recent reports have revealed that this also occurs at lower latitudes. Continued depletion of ozone in the lower stratosphere allows more UVR to reach the Earth's surface. F...
