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...

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

2010/3/17
Plants have evolved mechanisms to avoid and repair UV radiation damage; it is not surprising that photomorphogenic responses to UV-B and UV-C are often assumed to be adaptations to harmful radiation. ...
