Marine and continental aerosol effects on the upwelling solar radiation flux in Southern Portugal during the ACE-2 experiment
aerosol optical depth aerosol particle size-distributions aerosol radiative properties direct aerosol radiative forcing
2015/9/16
An overall number of 447 spectral series of aerosol optical depth were determined in the 0.4-3.7 mm wavelength
range by examining the IR-RAD sun-radiometer measurements carried out at Sagres (Portuga...
Interest in the effects of ultraviolet (UV) radiation on the marine environment surged after the Antarctic ozone hole was discovered in the mid 1980s. Much of the ensuing research has focused on quant...
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...
Ocean acidification exacerbates the effect of UV radiation on the calcifying phytoplankterEmiliania huxleyi
Ocean acidification UV radiation the calcifying phytoplankter Emiliania huxleyi
2014/4/17
Increasing atmospheric CO2 concentration affects calcification in most planktonic calcifiers. Both reduced or stimulated calcification under high CO2have been reported in the widespread coccolithophor...
Roles of phosphorus and ultraviolet radiation in the strength of phytoplankton–zooplankton coupling in a Mediterranean high mountain lake
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...
Stoichiometric dietary constraints influence the response of copepods to ultraviolet radiation-induced oxidative stress
Stoichiometric dietary constraints the response of copepods ultraviolet radiation-induced oxidative stress
2014/4/17
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
dinoflagellate Heterocapsa sp. We examined the effect of UVR and N availability on photosynthetic...

Elevated CO2 increases sensitivity ultraviolet radiation lacustrine phytoplankton assemblages
2014/4/17
This study tests the effects of elevated CO2 and ultraviolet radiation (UVR) on phytoplankton photosynthesis through in situ incubations in Lake Giles, Pennsylvania. In a first experiment, CO2 was sup...
UV-enhanced fish predation and the differential migration of zooplankton in response to UV radiation and fish
UV-enhanced fish predation zooplankton
2014/4/18
The intensity and spectral composition of visible light are known to influence fish predation on zooplankton.
However, in clear-water systems, ultraviolet (UV) radiation (UVR) may also influence fish...
