Measurements of photosynthesis, germination capacity and assessment of DNA damage
were carried out in the laboratory to determine the effect of different conditions of ultraviolet …

The importance of solar ultraviolet radiation (UVR, 290 to 400 nm), and UVB (290 to 320 nm)
in particular, as an environmental factor affecting the biology and ecology of coral reefs has …

Emiliania huxleyi (Lohm.) Hay et Miller is an important component of the phytoplankton in
open ocean waters. The sensitivity of this cosmopolitan alga to natural levels of UVB …

Most studies of the effects of UV radiation (radiation with wavelength,,: 400 nm) on biological
and chemical processes include some component that distinguishes how response varies …

The effects of herbivory and light on epilithic periphyton from Minor Creek (2,200 m above
sea level), a Swiss alpine stream, were examined by manipulating light intensity and the …

Summary 1 This laboratory study examined the effect of a gradient of UV‐B radiation (280–
320 nm) on photosynthesis and food quality of periphyton, the trophic base of many …

We performed in situ experiments during the austral summer of 1998 to quantify the mortality
of the freshwater copepod Boeckella gracilipes as a function of the UV dose. The copepods …

The effect of UV B radiation on photosynthesis and nitrogen uptake by an estuarine
phytoplankton community was investigated during a week long experiment, conducted in 8 …

The thesis reports studies of stabile instruments that are capable of detecting small
alterations in ultraviolet irradiation over a long period. A central theme in the work has been …
