In this paper, we review the literature and present some new data to examine the occurrence
and photophysics of the diverse hypericin‐like chromophores in heterotrichs, the …

Utraviolet radiation has provided an evolutionary challenge to life on Earth. Recent
increases in surficial ultraviolet B fluxes have focused attention on the role of UV radiation in …

The in situ Raman microspectroscopic properties of an Antarctic fungus are investigated to
assess the nature and the spatial localization of the main chromophores and to study their …

In photoresponsive ciliates, like Blepharisma japonicum and Stentor coeruleus, the
photoreceptor pigments responsible for photomotile reactions are hypericin‐type …

Abstract Analysis with 15 N NMR revealed that alanine, a universal cellular stress signal,
accumulates in etiolated duckweed plants exposed to 15‐min pulsed UV light, but not in the …

For life to exist, there must be an input of energy. Radiation, the movement of energy through
space, is the critical source of energy for life because visible radiation in the 400 to 700 nm …

We combined two‐photon fluorescence microscopy and spectroscopy to provide functional
images of UV‐B (280–315 nm) induced stress on an Antarctic fungus. Two‐photon …

The optical fluorescence properties of whole Antarctic fungal spores have been investigated
in order to evaluate the effects of artificial enhanced UV irradiation. The spores suspension …

Fabrea salina is a motile ciliate marine protozoan that belongs to the order Heterotrichida,
and which exhibits photomotile reactions. We report here the results of a study on motility …

A key question to answer studying the biological effects of ultraviolet radiation on planktonic
micro-organisms is whether they can perceive UV-B radiation as a sensory signal, likewise …
