Abstract Pigments absorbing 350–1,050 nm radiation have had an important role on the
Earth for at least 3.5 billion years. The ion pum** rhodopsins absorb blue and green …

A growing concern for overall health is driving a global market of natural ingredients not only
in the food industry but also in the cosmetic field. In this study, a screening on potential …

Polar seaweeds typically begin to grow in late winter–spring, around the time of sea-ice
breakup. They can grow under very low light enabling distributions to depths of 40 m …

Macroalgal (seaweed) beds and forests fuel coastal ecosystems and are rapidly
reorganizing under global change, but quantifying their functional structure still relies on …

Background Despite a global prevalence of photosynthetic organisms in the ocean's
mesophotic zone (30–200+ m depth), the mechanisms that enable photosynthesis to …

The red macroalgae Hydropuntia cornea, Gracilariopsis longissima and Halopithys incurva
were cultured for 14 d under laboratory conditions, in enriched seawater with a high nutrient …

Lessonia nigrescens and Durvillaea antarctica, two large sub-Antarctic brown algae from the
southern Chilean coast, were exposed to solar UV radiation in an outdoor system during a …

Current knowledge about the performance of floating seaweeds as dispersal vectors comes
mostly from mid latitudes (30–40), but phylogeographic studies suggest that long-distance …

Sargassum fusiforme is often adversely affected by epiphytic algae during its cultivation.
However, the biological differences between S. fusiforme and the epiphytic algae have not …

Giant kelp Macrocystis pyrifera is a brown alga with extensive global distribution, however,
recent evidence suggests that its dynamics presents high degree of regional variability. In …
