The effects of ultraviolet radiation in the biological relevant wavebands of UV-A (315–
400nm) and UV-B (280–315nm) on algae have become an important issue as a man-made …

Antarctic terrestrial ecosystems experience some of the most extreme growth conditions on
Earth and are characterized by extreme aridity and subzero temperatures. Antarctic …

We report a meta‐analysis of data from 34 field studies into the effects of ultraviolet B (UVB)
radiation on Arctic and Antarctic bryophytes and angiosperms. The studies measured plant …

Global warming is a critical issue and has great impact on all living organisms, including
algae. Generally, algae play significant roles in aquatic ecosystems and employ diverse …

Main conclusion We introduced a novel combination of chromatographic techniques for the
purification and analysis of a new UV-sunscreen mycosporine-like amino acid (MAA) in the …

The determination of physiological tolerance ranges of photosynthetic species and of the
biochemical mechanisms underneath are fundamental to identify target processes and …

Despite considerable research attention during the last 10 years, the distribution and
biogeography of protists remain as highly controversial issues. The presumably huge …

Microscopic green algae are among the most widespread microrganisms occurring in
terrestrial environments. For more than two centuries, generalizations on the diversity and …

Trebouxiophytes of the genus Prasiola are well known in Antarctica, where they are among
the most important primary producers. Although many aspects of their biology have been …
