Short-term effect of UVR on vertical distribution of Cyrtograpsus altimanus and Alexandrium tamarense from Atlantic Patagonia
(Pontificia Universidad Católica de Valparaíso, 2017)
Temperature benefits the photosynthetic performance of the diatoms Chaetoceros gracilis and Thalassiosira weissflogii when exposed to UVR
(Elsevier Science Sa, 2010-12)
The aim of this study was to assess the combined effects of temperature and UVR on the photosynthesis performance of two diatoms - Chaetoceros gracilis and Thalassiosira weissflogii. In particular, we evaluated the role ...
Variability of UVR effects on photosynthesis of summer phytoplankton assemblages from a tropical coastal area of the South China Sea.
(Wiley Blackwell Publishing, Inc, 2007-12)
From June to September 2005, we carried out experiments todetermine the ultraviolet radiation (UVR) -induced photoinhibitionof summer phytoplankton assemblages from a coastal site ofthe South China Sea. Variability in ...
Plankton dynamics and photosynthesis responses in a eutrophic lake in Patagonia (Argentina): influence of grazer abundance and UVR
(Pontificia Universidad Católica de Valparaíso<BR>Facultad de Recursos Naturales<BR>Escuela de Ciencias del Mar, 2011)
Current and predicted global change impacts of UVR, temperature and nutrient inputs on photosynthesis and respiration of key marine phytoplankton groups
(Elsevier Science, 2014-12)
Multiple stressors are altering primary production in coastal and estuarine systems; however, it is difficult to predict their combined impacts due to the scarcity of multifactorial experiments. Photosynthesis, respiration, ...
Vulnerability of mixotrophic algae to nutrient pulses and UVR in an oligotrophic Southern and Northern Hemisphere lake
(Nature Publishing Group, 2017-12)
Nutrient inputs and ultraviolet radiation (UVR) are global factors affecting the structure and functioning of aquatic ecosystems, particularly clear-water ecosystems. We performed experiments in two model lakes highly ...
Ultraviolet-B-Induced Stomatal Closure in Arabidopsis is Regulated by the UV RESISTANCE LOCUS8 Photoreceptor in a Nitric Oxide-Dependent Mechanism
(American Society of Plant Biologist, 2014-02)
UV RESISTANCE LOCUS8 (UVR8) signaling involves CONSTITUTIVELY PHOTOMORPHOGENIC1, the ELONGATED HYPOCOTYL5 (HY5) transcription factor, and the closely related HY5 HOMOLOG. Some UV-B responses mediated by UVR8 are also ...
Physiological responses and toxin production of Microcystis aeruginosa in short-term exposure to solar UV radiation
(Royal Society of Chemistry, 2017-11)
The aim of this study was to evaluate the effects of short-term (hours) exposure to solar UV radiation (UVR, 280-400 nm) on the physiology of Microcystis aeruginosa. Three solar radiation treatments were implemented: (i) ...
Análisis del impacto económico de las modalidades de UVR, para adquisición de vivienda en el departamento del Magdalena

Ultraviolet studies upon phytoplankton from freshwater and marine ecosystems of Argentina
(E Schweizerbartsche Verlags, 2014-07-07)
Argentina, with its large latitudinal extent, has an important number of water bodies with different light scenarios therefore, variable responses to solar radiation are found. In this article we review the impact of UVR ...
