• Ultraviolet radiation shapes seaweed communities (2006, background): “The results show that Antarctic macroalgal recruits are particularly sensitive to UV-exposure during their first month of development, but that effects change during succession.”
• Patterns of photosynthesis in 18 species of intertidal macroalgae from southern Chile (2004, background): “Those results indicated values as high as 10 mg g–1 DW, exceeding maximal MAA contents measured in species from other geographical locations (<7.8 mg g–1 DW; Karsten et al. 1998, Hoyer et al. 2001).”
• Chloroidium, a common terrestrial coccoid green alga previously assigned to Chlorella (Trebouxiophyceae, Chlorophyta) (2010, background): “Although not systematically investigated, SAG 2061 (Cd. ellipsoideum comb. nov.) contained the so-called 324 nmMAA (Karsten et al. 2005b), which was previously described in Prasiola crispa ssp. antarctica (Hoyer et al., 2001).”
• Induction of sunscreen compounds in Antarctic macroalgae by different radiation conditions (2002, methodology): “The MAA-containing species of this study belong to the two physiological groups II and III, classified by Hoyer et al. (2001) .”
• MYCOSPORINE‐LIKE AMINO ACIDS AND PHYLOGENIES IN GREEN ALGAE: PRASIOLA AND ITS RELATIVES FROM THE TREBOUXIOPHYCEAE (CHLOROPHYTA) 1 (2005, methodology): “…was done by spectra, retention time, and co-chromatography with standards extracted from the marine green macroalga Prasiola crispa ssp. antarctica (Hoyer et al. 2001), the red macroalgae Chondrus crispus Stackhouse (Karsten et al. 1998a), and Porphyra umbilicalis (L.) Kützing, the lichen Lichina…”
• Ultraviolet-absorbing mycosporine-like amino acids in red macroalgae from Chile (2004, background): “A third group included species that possess a basic MAA level, which is adjusted in relation to changes in irradiation (Hoyer et al. 2001).”
• Enzymatic defences against photooxidative stress induced by ultraviolet radiation in Arctic marine macroalgae (2002, background): “In Prasiola crispa ssp. antarctica from Antarctica, high amounts of two new, so far chemically uncharacterized, mycosporine-like amino acids (MAAs) have been reported (Hoyer et al. 2001).”
• Seasonal variation in ecophysiological patterns in macroalgae from an Arctic fjord. II. Pigment accumulation and biochemical defence systems against high light stress (2002, background): “While experimental evidence for the role of MAAs as UV protectants in macroalgae is still circumstantial (Hoyer et al. 2001), studies on photosynthesis of unicellular microalgae proved that MAAs indeed act as spectrally specific UV sunscreens (Neale et al. 1998).”
• Life strategy, ecophysiology and ecology of seaweeds in polar waters (2007, background): “Red algae from both polar regions have been shown to produce mycosporine-like amino acids (MAA) as photoprotective substances (e.g., McClintock and Karentz 1997; Hoyer et al. 2001; Aguilera et al. 2002).”
• Large scale importance of sea ice biology in the Southern Ocean (2004, result): “This is consistent with previous results showing that MAA content per cell decreases with the depth of the water for both phytoplankton and macroalgal communities (Jeffery et al. 1999, Hoyer et al. 2001).”
• AMMONIUM AND UV RADIATION STIMULATE THE ACCUMULATION OF MYCOSPORINE‐LIKE AMINO ACIDS IN PORPHYRA COLUMBINA (RHODOPHYTA) FROM PATAGONIA, ARGENTINA 1 (2004, background): “The location in the water column, and thus the amount of solar radiation, is also important because it was demonstrated that the accumulation of MAAs was greater in intertidal than in subtidal algae (Karsten et al. 1998b, Karsten and Wiencke 1999, Hoyer et al. 2001).”
• Antarctic marine chemical ecology: what is next? (2008, background): “They are mainly present in red algae, and only in some green algae, while being scarce in brown algae (Karentz et al. 1991; Karentz 1994; Hoyer et al. 2001; Rautenberger & Bischof 2006).”
• Mycosporine-like amino acids and related Gadusols: biosynthesis, acumulation, and UV-protective functions in aquatic organisms. (2002, background): “Some deep-water species of Rhodophyta seemingly lack the capacity to produce MAAs, whereas some littoral species have constitutively high concentrations (94).”
