Linkages between stratospheric ozone, UV radiation and climate change and their implications for terrestrial ecosystems

摘要: Exposure of plants and animals to ultraviolet-B radiation (UV-B; 280–315 nm) is modified by stratospheric ozone dynamics climate change. Even though stabilisation projected recovery expected curtail future increases in UV-B at the Earth's surface, on-going changes are increasingly exposing novel combinations other change factors (e.g., ultraviolet-A visible radiation, water availability, temperature elevated carbon dioxide). Climate also shifting vegetation cover, geographic ranges species, seasonal timing development, which further modifies exposure radiation. Since our last assessment, there has been increased understanding underlying mechanisms perceive eliciting growth, development tolerances abiotic biotic factors. However, major questions remain on how interacting with modify production quality crops, as well important ecosystem processes such plant animal competition, pest–pathogen interactions, decomposition dead matter (litter).
