Metabolic and behavioral responses of the reef fish Patagonotothen cornucola to ultraviolet radiation: Influence of the diet
(Elsevier Science, 2016-01)
Most of the studies devoted to assess the effects of ultraviolet radiation (UVR) on fishes have been done with early life stages (i.e., eggs and larvae) as they are the most vulnerable to these wavelengths; however, the ...
Photosensitivity of Cucumber (Cucumis sativus L.) Seedlings Exposed to Ultraviolet-B Radiation
(Instituto de Investigaciones Agropecuarias, INIA, 2010)
Sex-dependent effects of ultraviolet radiation on the marine amphipod Ampithoe valida (Ampithoidae)
(Elsevier Science, 2015-03-09)
The combined effects of solar radiation and diet on the marine amphipod Amphitoe valida were investigated exposing individuals to two solar radiation treatments: PAB (>280 nm, PAR+UV-A+UV-B) and P (>400 nm, only PAR), and ...
In situ Responses of Phytoplankton from the Subtropical Lake La Angostura (Tucumán, Argentina) in Relation to Solar Ultraviolet Radiation Exposure and Mixing Conditions
In situ experiments were conducted at various depths in the water column to determine the effects of solar ultraviolet radiation (UVR, 280–400 nm) on photosynthesis of natural phytoplankton assemblages from the subtropical ...
Photosensitivity of cucumber (Cucumis sativus L.) seedlings exposed to ultraviolet-B radiation Fotosensibilidad de plantines de pepino de ensalada (Cucumis sativus L.) expuestos a radiación ultravioleta del tipo B
The intensity of ultraviolet-B radiation (UV-B) has increased on the Earth́s surface due to the stratospheric ozone depletion, causing an adverse effect on a wide range of species, such as morphological, physiological, and ...
Improving the detection limits of near infrared spectroscopy in the determination of aromatic hydrocarbons in water employing a silicone sensing phase
(Elsevier Science SaLausanneSuíça, 2007)
Effects of ultraviolet-B radiation on common bean (Phaseolus vulgaris L.) plants grown under nitrogen deficiency
This work reports on the significance of UV-B absorbing compounds and DNA photorepair in protecting bean plants from UV-B radiation under nitrogen restriction. Bean plants grown in sterile vermiculite and irrigated ...
Sensitivity of yellow passion fruit plants to ultraviolet-B radiation
The objective of this work was to evaluate the effects of UV-B radiation on the vegetative growth and on the gas exchange characteristics of passion fruit plants (Passiflora edulis) grown in greenhouse. The average unweighted ...
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 ...
