Photosynthesis in Marine Macroalgae (2003, background): “During this time, algal spores were found to be the most light-sensitive life history stage of the studied brown algae and are strongly affected by increased UV-B radiation, both in respect to their photosynthetic performance and their susceptibility to DNA damage (Wiencke et al. 2000).”
Susceptibility of zoospores to UV radiation determines upper depth distribution limit of Arctic kelps: evidence through field experiments (2006, background): “Under ambient solar radiation, over various time intervals, about 10 times lower UVBR doses were recorded compared with those in standard laboratory experiments (data taken from Wiencke, Clayton & Schoenwaelder 2004), probably explaining lower laboratory germination under PAB filters than under PA c”
The genus Laminaria sensu lato : recent insights and developments (2008, background): “This has been shown in a number of kelps from the Arctic, the N Atlantic and the S Pacific (Table 7; Roleda et al., 2005, 2006d,e; Véliz et al., 2006; Wiencke et al., 2000, 2007).”
PAR and UVBR effects on photosynthesis, viability, growth and DNA in different life stages of two coexisting Gigartinales: implications for recruitment and zonation pattern (2004, methodology): “Only 1 study has investigated DNA damage on macroalgal spores (Wiencke et al. 2000).”
Sensitivity of Laminariales zoospores from Helgoland (North Sea) to ultraviolet and photosynthetically active radiation: implications for depth distribution and seasonal reproduction (2005, background): “The impact of UVR on the germination capacity of brown algal zoospores inhabiting different water depth has been demonstrated for Laminariales from Spitsbergen and from southern Spain (Wiencke et al. 2000, 2004).”
Effects of UV radiation and temperature on growth of germlings of three species of Fucus (Phaeophyceae) (2003, background): “Wiencke et al. (2000) observed a direct relationship between DNA damage and mortality of zoospores of kelp species, and also suggested that the motility or phototaxis of these biflagellate zoospores might be affected by UVR as in the flagellateEuglena gracilis(Ekelund, 1996).”
INTERACTIONS BETWEEN UV RADIATION AND TEMPERATURE LIMIT INFERENCES FROM SINGLE‐FACTOR EXPERIMENTS 1 (2003, background): “Total emergence time (Doty 1946, Druehl and Green 1982, Swinbanks 1982) and UVR (Dring et al. 1996, Swanson and Druehl 2000, Wiencke et al. 2000) both have been suggested as possible causes of zonation.”
EFFECTS OF UV RADIATION ON GROWTH AND PHLOROTANNINS IN FUCUS GARDNERI (PHAEOPHYCEAE) JUVENILES AND EMBRYOS 1 (2004, background): “Early developmental stages of intertidal algae can be particularly vulnerable to UV stress (Major and Davison 1998, Wiencke et al. 2000, Coelho et al. 2001, Hoffman et al. 2003).”
Ultraviolet radiation shapes seaweed communities (2006, background): “The zoospores e.g. of the more advanced families of the Laminariales, the Alariaceae, Laminariaceae and Lessoniaceae only contain one small chloroplast (Henry and Cole 1982), with comparatively low photosynthetic activity (Amsler and Neushul 1991; Wiencke et al. 2000).”
Seaweed Biology (2013, background): “During this time, algal spores were found to be the most light-sensitive life history stage of the studied brown algae and are strongly affected by increased UV-B radiation, both in respect to their photosynthetic performance and their susceptibility to DNA damage (Wiencke et al. 2000).”
Interactive effects of UV radiation and temperature on microstages of Laminariales (Phaeophyceae) from the Arctic and North Sea (2008, result): “Conformingly to UV-B susceptibilities of Arctic zoospores at 12°C (Table 2), similar results were obtained in laboratory UV experiments at 10°C (Wiencke et al. 2000, 2004, Roleda et al. 2006), as well as in field exposures at fjord temperature (Wiencke et al. 2006).”
Photoprotective substances in Antarctic macroalgae and their variation with respect to depth distribution, different tissues and developmental stages (2001, background): “MAA accumulation in different developmental stages Spores are the most sensitive developmental stages against UV stress in the life history of macroalgae, as shown for various brown algae (mostly Laminariales) (Wiencke et al. 2000).”
