The role of ultraviolet radiation and fish in regulating the vertical distribution of Daphnia
The role of ultraviolet radiation fish in regulating vertical distribution of Daphnia
2014/4/2
Previous studies have demonstrated independent effects of both solar ultraviolet radiation (UV; 280–400 nm) and planktivorous fish on the vertical distribution of Daphnia. We examined the behavioral r...

Toward a more comprehensive theory of zooplankton diel vertical migration: Integrating ultraviolet radiation and water transparency into the biotic paradigm
comprehensive theory zooplankton diel vertical migration Integrating ultraviolet radiation water transparency biotic paradigm
2014/4/4
The current prevailing theory of diel vertical migration (DVM) of zooplankton is focused largely on two biotic drivers: food and predation. Yet recent evidence suggests that abiotic drivers such as da...
