Solar UVR-induced DNA damage and inhibition of photosynthesis in phytoplankton from Andean lakes of Argentina
(E. Schweizerbart'sche Verlagsbuchhandlung, 2004-10)
During January 1999, studies were carried out in temperate lakes of the Andean region of Argentina (41° S, 71° W) to determine the short-term effects of solar ultraviolet radiation (UVR, 280 – 400 nm) upon natural phytoplankton ...
Effects of N supply on the accumulation of photosynthetic pigments and photoprotectors in Gracilaria tenuistipitata (Rhodophyta) cultured under UV radiation
(SPRINGER, 2011)
We have studied the effects of nitrate supply under photosynthetic active radiation (PAR) plus ultraviolet radiation (UVR) exposure on photosynthetic pigments (chlorophyll a and carotenoids), photoprotective UV screen ...

Vulnerability and acclimation of Mediterranean Sea macroalgae to environmental stress related to climate change: use of physiological state indicators
(2015)
In this thesis, the vulnerability and capacity of acclimation to environmental stress related to Climate change mainly in Cystoseira tamariscifolia and other species as Ellisolandia elongata, Cystoseira compressa and Padina ...
Differential responses of Nostoc sphaeroides and Arthrospira platensis to solar ultraviolet radiation exposure
(Springer, 2006-04)
During October to December 2003 we carried out experiments to assess the impact of high solar radiation levels (as normally occurring in a tropical region of Southern China) on the cyanobacteria Nostoc sphaeroides and ...
UVR-induced photoinhibition of summer marine phytoplankton communities from Patagonia
(Springer, 2008-07)
During austral summer 2006, experiments were carried out to evaluate the effects of ultraviolet radiation (UVR, 280-400 nm) on carbon fixation of natural phytoplankton assemblages from Patagonia (Argentina). Surface water ...
Photoreceptor Signaling Networks in Plant Responses to Shade
(Annual Reviews, 2013-04)
The dynamic light environment of vegetation canopies is perceived by phytochromes, cryptochromes, phototropins, and UV RESISTANCE LOCUS 8 (UVR8). These receptors control avoidance responses to preclude exposure to limiting ...
Solar UV radiation modulates daily production and DNA damage of marine bacterioplankton from a productive upwelling zone (36°S), Chile
(Elsevier Science, 2007-04)
In upwelling ecosystems, such as the Humboldt Current system (HCS) off Concepción, the effects of solar radiation on bacterioplankton incorporation rates have been related to previous light acclimation and responses to ...
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 ...
