Are volatile unsaturated aldehydes from diatoms the main line of chemical defence against copepods (2002, background): “However, the liberation of free EPA from lipids was found to act as a defence against grazers, and elevated concentrations of this fatty acid were acutely toxic to the anostracan grazer Thamnocephalus platyurus (Jüttner 2001).”
Fatty acid composition of several wild microalgae and cyanobacteria, with a focus on eicosapentaenoic, docosahexaenoic and α-linolenic acids for eventual dietary uses (2011, background): “tricornutum against both Gram-positive and -negative bacteria has been attributed to EPA (Ward & Singh, 2005); this PUFA is found chiefly as a polar lipid species in such structural cell components asmembranes, and apparently plays a role inmicroalgal defense— as it is toxic to grazers (Jüttner, 200”
ALLELOCHEMICALS OF BOTRYOCOCCUS BRAUNII (CHLOROPHYCEAE) 1 (2004, background): “Some active compounds have been isolated and identified (Gross et al. 1991, Bagchi 1995, Papke et al. 1997, Jüttner 2001, Mundt et al. 2003).”
Chemical defense in the microplankton II: Inhibition of protist feeding by β‐dimethylsulfoniopropionate (DMSP) (2003, background): “…acids and their aldehyde reaction products causing acute toxicity or reduced reproduction rates in crustacean zooplankton (Miralto et al. 1999; Pohnert 2000; Juttner 2001), there appear to be no previously published reports of phytoplankton-derived defense compounds active against protist grazing.”
Consumer effects decline with prey diversity (2004, methodology): “To assess the importance of algal diversity as an explanatory variable of grazer effect size, we used an informationtheoretic approach to judge the relative likelihood of models with and without algal diversity terms included (Burnham & Anderson 2002; Johnson & Omland 2004 ).”
Ecological functions of volatile organic compounds in aquatic systems (2007, background): “These substances probably function as ‘warning cues’, since upon cell damage, the diatoms release high amounts of the polyunsaturated eicosapentaenoic acid (EPA) which is highly toxic for crustacean herbivores (Jüttner 2001).”
LIPID, FATTY ACID, AND STEROL COMPOSITION OF EIGHT SPECIES OF KARENIACEAE (DINOPHYTA): CHEMOTAXONOMY AND PUTATIVE LIPID PHYCOTOXINS 1 (2007, background): “Jüttner (2001) showed that low levels of FFA were released by diatom biofilms, which provided protection against grazing by fairy shrimp.”
Harmful Algal Blooms (2015, background): “…deterrents at low-moderate levels (as would be encountered in close proximity to a bloom; Jüttner, 2005; Watson et al., 2007b), and toxins or tetarogens at higher doses (e.g., released from diatom biofilms or ingested material in grazer guts; Jüttner, 2001; Ianora et al, 2003; Watson et al., 2010).”
Antibacterial free fatty acids: activities, mechanisms of action and biotechnological potential (2010, background): “Therefore, the toxic FFAs act to 11 reduce grazer numbers and ultimately grazing pressure (Jüttner 2001).”
