Quantifying the drivers of zooplankton vertical migration: what are the relative roles of ultraviolet radiation and visual predator avoidance?
Leach T. Quantifying the drivers of zooplankton vertical migration: what are the relative roles of ultraviolet radiation and visual predator avoidance?. Research Permit and Reporting System
Every day zooplankton in lakes migrate up and down in the water column. The current explanation of zooplankton DVM is largely focused on two biotic drivers: food availability and visual predation. However, recent experiments in high ultraviolet radiation (UV) transparency, fishless lakes suggest that UV radiation and temperature are also important. Using a combination of observational data and field experiments we assessed the role of UV in driving these migrations.
