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...
通过实验生态学和生物化学的方法, 研究了 UV-B辐射对杜氏盐藻、小角毛藻的生长、叶绿素含量、可溶性蛋白含量、超氧化物歧化酶活力的影响. 结果表明: (1) UV-B 辐射对小角毛藻的生长起促进作用, 高剂量 UV-B辐射对盐藻的生长具有一定抑制作用. (2) 2 种微藻叶绿素含量均低于对照组, UV-B 辐射使盐藻叶绿素含量先下降后升高, 而小角毛藻则随辐射剂量的增加呈现下降趋势. (3...
Zooplankton vertical migration and plasticity of pigmentation arising from simultaneous UV and predation threats
Zooplankton vertical migration plasticity of pigmentation arising simultaneous UV predation threats
2014/4/17
We assessed how zooplankton (copepods) handle the simultaneous threats of predators and ultraviolet (UV) radiation and whether they respond with changes in pigmentation, vertical migration, or both. W...
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...
Zooplankton accumulate several groups of photoprotective compounds to shield against damaging ultraviolet radiation (UV). One of these groups, the carotenoids, makes the animals more conspicuous to vi...
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...
Picophytoplankton cell death induced by UV radiation: Evidence for oceanic Atlantic communities
Picophytoplankton cell death induced oceanic Atlantic communities
2014/4/23
We analyzed the effect of ambient levels of visible and ultraviolet radiation (UVR) on picophytoplankton cell
death by exposing natural communities of picophytoplankton (Prochlorococcus, Synechococcu...
Effect of UV-B and different PAR intensities on the primary production of the mixotrophic planktonic ciliate Stentor araucanus
UV-B different PAR intensities primary production mixotrophic planktonic ciliate Stentor araucanus

Contribution of absorption and scattering to the attenuation of UV and photosynthetically available radiation in Lake Biwa
absorption and scattering attenuation of UV photosynthetically available radiation Lake Biwa
2014/5/26
Underwater ultraviolet (UV) attenuation is typically modeled using correlative relationships between UV attenuation and dissolved organic carbon (DOC) concentration or colored dissolved organic matter...
The distribution of the planktonic crustacean Daphnia and the occurrence of ultraviolet (UV)-protective melanin pigmentation in its body wall were studied in relation to the UV transparency in subarct...
Zooplankton survival and reproduction responses to damaging UV radiation: A test of reciprocity and photoenzymatic repair
Zooplankton survival reproduction responses damaging UV radiation A test of reciprocity photoenzymatic repair
2014/6/9
As stratospheric ozone concentrations are reduced, exposure of organisms to damaging ultraviolet radiation (UVR) reaching the earth increases. Many organisms can repair DNA damaged by UVR through phot...
