Short-term effect of UVR on vertical distribution of Cyrtograpsus altimanus and Alexandrium tamarense from Atlantic Patagonia

Many marine species spend part of their development in upper layers of the water column, where they may be exposed to solar ultraviolet radiation (UVR). For many of these species, light is one of the key environmental clues which triggers behaviorally-mediated adjustments in vertical distribution. W...
