• Interactions between Planktonic Microalgae and Protozoan Grazers1 (2004, background): “…confirmation that a number of diatom species negatively influence the reproduction of herbivorous co- pepods (Ban et al. 1997 and references therein), and this effect has been attributed to the presence of reactive aldehydes acting as mitotic inhibitors (Miralto et al. 1999; Pohnert et al. 2002).”
• Inhibition of population growth in the copepods Acartia clausi and Calanus helgolandicus during diatom blooms (2003, background): “Pond et al. (1996) found that hatching viability for Calanus helgolandicus was consistently high, with a seasonal mean of 83%, at a coastal station in the western English Channel off Plymouth during January to September 1993, and that hatching success was not correlated with the abundance of…”
• Copepod reproduction is unaffected by diatom aldehydes or lipid composition (2008, background): “Also the earlier results of Pohnert et al. (2002) on the divergent response in the egg viability of Calanus helgolandicus to the same TR strains (TR 1647, TR 1018) could not be confirmed.”
• Ecological functions of volatile organic compounds in aquatic systems (2007, background): “However, the particular lipoxygenases and lyases are highly species- and sometimes even strain-specific (Wendel and Jüttner 1996; Pohnert et al. 2002).”
• Survey of the Chemical Defence Potential of Diatoms: Screening of Fifty Species for α,β,γ,δ-unsaturated aldehydes (2005, methodology): “…of 50 different species was investigated, with an emphasis on the family Thalassiosiraceae and the species Phaeodactylum tricornutum, because these diatoms are widely used in bioassays on the reproductive success of copepods (Miralto et al., 1999; Pohnert et al., 2002; Paffenhöfer et al., 2005).”
• GROWTH INHIBITION AND TOXICITY OF THE DIATOM ALDEHYDE 2‐TRANS, 4‐TRANS‐DECADIENAL ON THALASSIOSIRA WEISSFLOGII (BACILLARIOPHYCEAE) 1 (2005, background): “Our results present the first direct evidence that aldehydes are toxic for diatoms, supporting the hypothesis that this activated mechanism of production represents an effective way of avoiding self-toxicity (Pohnert 2000, 2002, Pohnert et al. 2002).”
