The insidious effect of diatoms on copepod reproduction
The structure of the three aldehydes isolated from diatoms that are responsible for this biological activity are reported, and it is shown that these compounds arrest embryonic development in copepod and sea urchin bioassays and have antiproliferative and apoptotic effects on human carcinoma cells.

Induced defences in marine and freshwater phytoplankton: a review
The categorization of inducible defences in phytoplankton in terms of the responsible induction mechanism provides guidance for future work, as hardly any of the available studies on marine or freshwater plankton have performed all the treatments that are required to pinpoint the actual cue(s) for induction.

Aldehyde suppression of copepod recruitment in blooms of a ubiquitous planktonic diatom
A transgenerational plant–herbivore interaction could explain the recurringly inefficient use of a predictable, potentially valuable food resource—the spring diatom bloom—by marine zooplankton. Expand
Growth inhibition of cultured marine phytoplankton by toxic algal-derived polyunsaturated aldehydes.
Concentrations used in this study are in a significant range for affecting growth and performance of phytoplankton living in close vicinity of PUA-producing algae, suggesting that PUAs may act as allelochemicals by mediating interactions among planktonic organisms. Expand
A marine diatom-derived aldehyde induces apoptosis in copepod and sea urchin embryos
DD induced apoptosis and also activated a caspase-3-like protease in sea urchin embryos, indicating that α,β-unsaturation of the molecule, coupled with the aldehyde group, is responsible for the greater biological activity of DD. Expand
The paradox of diatom-copepod interactions*
Analysis of the reproductive response of a number of copepod species to different diatom species in a variety of temperate and subarctic freshwater, estuarine, and coastal ocean environments presents strong evidence that diatom diets are in fact inferior forCopepod reproduction. Expand
Variability in the Hydrographic and Biological Features of the Gulf of Naples
. Recent observations of physico-chemical and biological parameters in the Gulf of Naples are summarized. The water masses present within the Gulf during the various periods of the year areExpand
Gene expression patterns and stress response in marine copepods.
The data indicate high inter- and intra-species variability in copepod response, depending on the type of stressor tested, the concentration and exposure time, and the enzyme isoform studied. Expand
Age and nutrient limitation enhance polyunsaturated aldehyde production in marine diatoms.
The plasticity of PUA production with age of the culture supports the hypothesis of a direct link between toxin production and cell physiological state and holds true during blooms, grazers feeding at the end of a bloom would be more affected than early-bloom grazers. Expand
