The insidious effect of diatoms on copepod reproduction
The productive regions of the ocean are characterized by seasonal blooms of phytoplankton which are generally dominated by diatoms. This algal class has, therefore, traditionally been regarded asExpand

A Stress Surveillance System Based on Calcium and Nitric Oxide in Marine Diatoms
Diatoms are an important group of eukaryotic phytoplankton, responsible for about 20% of global primary productivity. Study of the functional role of chemical signaling within phytoplanktonExpand

Aldehyde suppression of copepod recruitment in blooms of a ubiquitous planktonic diatom
The growth cycle in nutrient-rich, aquatic environments starts with a diatom bloom that ends in mass sinking of ungrazed cells and phytodetritus. The low grazing pressure on these blooms has beenExpand

A marine diatom-derived aldehyde induces apoptosis in copepod and sea urchin embryos
SUMMARY The diatom-derived aldehyde 2-trans-4-trans-decadienal (DD) was tested as an apoptogenic inducer in both copepod and sea urchin embryos, using terminal-deoxynucleotidyl-transferase-mediatedExpand

The paradox of diatom-copepod interactions*
Traditionally, diatoms have been associated w ~ t h productive pelagic food chains that lead, through suspensionfeeding planktonic copepods, to top consumers and important fisheries Here, 15Expand

The role of complex lipids in the synthesis of bioactive aldehydes of the marine diatom Skeletonema costatum.
Diatoms are unicellular plants broadly present in freshwater and marine ecosystems, where they play a primary role in sustaining the marine food chain. In the last 10 years, there has beenExpand

LOX‐Induced Lipid Peroxidation Mechanism Responsible for the Detrimental Effect of Marine Diatoms on Zooplankton Grazers
Some marine diatoms negatively affect the reproduction of dominant zooplankton grazers such as copepods, thus compromising the transfer of energy through the marine food chains. In this paper, theExpand

Age and nutrient limitation enhance polyunsaturated aldehyde production in marine diatoms.
Skeletonema marinoi produces 2,4-heptadienal, 2,4-octadienal, and 2,4,7-octatrienal, the latter only in traces. In nutrient-replete cultures, the production of potentially defensive polyunsaturatedExpand

A comparative study of the inhibitory effect of diatoms on the reproductive biology of the copepod Temora stylifera
Egg production and viability in the copepod Temora stylifera (collected in the Bay of Naples, Italy in 1992) were strongly dependent on food type. A flagellate (Isochrysis galbana) diet induced theExpand

Decoupling of copepod grazing rates, fecundity and egg-hatching success on mixed and alternating diatom and dinoflagellate diets
Experiments were conducted over 10 to 20 d periods to study the grazing and repro- ductive success of the copepod Temora stylifera fed on unialgal cultures of the diatom Thalassiosira rotula (THA) orExpand
