The health of freshwater and marine ecosystems is critical to life on Earth. The impact of
solar UV-B radiation is one potential stress factor that can have a negative impact on the …

Polar Regions are unique and highly prolific ecosystems characterized by extreme
environmental gradients. Photosynthetic autotrophs, the base of the food web, have had to …

Microalgae are a novel source of sustainable natural antioxidants with various applications,
including food preservation. To optimize antioxidant production in microalgae, we …

Nanoscale zero-valent iron particles (nZVI), with sizes smaller than 100 nm, are promising
for environmental remediation of polluted water, soil and sediments. nZVI particles have …

Solar radiation represents a key abiotic factor in the evolution of life in the oceans. In
general, marine, biota—particularly in euphotic and dysphotic zones—depends directly or …

This chapter reviews the nature of pigment variations in phytoplankton in response to
changes in light regime (irradiance, spectral composition and daylength). These changes …

The cosmopolitan coccolithophore Emiliania huxleyi is a unicellular eukaryotic alga
responsible for vast blooms in the ocean. These blooms have immense impact on large …

Kelps, brown algae of the order Laminariales, dominate rocky shores and form huge kelp
beds which provide habitat and nurseries for various marine organisms. Whereas the basic …

We studied the interactive effects of pCO2 and growth light on the coastal marine diatom
Thalassiosira pseudonana CCMP 1335 growing under ambient and expected end-of-the …

A natural marine phytoplankton assemblage from a coastal environment of Antarctica was
experimentally exposed to low salinity sea water (30 vs 34 in the control) during 8 days in …
