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...

Roles of phosphorus ultraviolet radiation
2014/4/17
Ultraviolet solar radiation (UVR) and atmospheric nutrient inputs associated with aerosols are major
worldwide stressors that simultaneously affect species and the interaction among them. A 2 3 5 fie...

We carried out field experiments in two clear mountain lakes of both hemispheres (Lake Los Ca′ ntaros,Patagonia, Argentina, and Lake La Caldera, Sierra Nevada, Spain) performing a full factorial desig...
Photoprotection mechanisms against ultraviolet radiation in Heterocapsa sp. (Dinophyceae) are influenced by nitrogen availability: Mycosporine-like amino acids vs. xanthophyll cycle
Heterocapsa sp Photoprotection mechanisms
2014/4/16
The photoprotective and acclimation capacity against ultraviolet radiation (UVR) was assessed for the
