Effect of UV-B radiation on the contents of UV-B absorbing compounds and photosynthetic parameters in Parmotrema austrosinense from two contrasting habitats
(Wiley Blackwell Publishing, Inc, 2018-09)
We studied the resistance of Parmotrema austrosinense to UV-B stress. We focused on the effects of a high dose UV-B radiation on the content of chlorophylls, carotenoids and UV-B screening compounds. Photosynthetic parameters ...
Absorbance detector for high performance liquid chromatography based on a deep-UV light-emitting diode at 235 nm
(2017-08-25)
In this communication, we describe a flow-through optical absorption detector for HPLC using for the first time a deep-UV light-emitting diode with an emission band at 235 nm as light source. The detector is also comprised ...
Ecophysiological strategies in response to UV-B radiation stress in cultures of temperate microalgae isolated from the Pacific coast of South America

UV-radiation effects on photosynthesis, photosynthetic pigments and UV-absorbing substances in three species of tropical lotic macroalgae
(Brazilian Soc Plant Physiology, 2018-09-01)
Freshwater algae inhabiting shallow waters are most effectively affected by UV radiation. The aim of this study was to analyze the photosynthetic performance (parameters derived of chlorophyll fluorescence), chlorophyll a ...
Functional acclimation to solar UV-B radiation in Gunnera magellanica, a native plant species of southernmost Patagonia
(Wiley Blackwell Publishing, Inc, 2003-12)
The ecosystems of Tierra del Fuego (in southern Patagonia, Argentina) are seasonally exposed to elevated levels of ultraviolet-B radiation (UV-B: 280-315 nm), due to the passage of the 'ozone hole' over this region. In the ...

Combined effects of UVR and temperature on the survival of crab larvae (Zoea I) from Patagonia: The role of UV-absorbing compounds
(Molecular Diversity Preservation International, 2010-05)
The aim of our study was to assess the combined impact of UVR (280-400 nm) and temperature on the first larval stage (Zoea I) of three crab species from the Patagonian coast: Cyrtograpsus altimanus, C. angulatus, and ...
UV-absorbing compounds in Porphyra haitanensis (Rhodophyta) with special reference to effects of desiccation
(Springer, 2008-08)
The intertidal red alga Porphyra haitanensis Chang et Zheng is episodically desiccated and exposed to high levels of solar radiation at low tide during emersion. However, little has been documented on the relationship ...
