Growth, dark respiration rate, photosynthetic parameters, and chemical composition were determined for Emiliania huxleyi (Lohmann) Hay et Mohler acclimated to different combinations of day length (12, 18, 24 h) and irradiance (30, 100, 200, 800 μmol

Light-saturated photosynthesis (Pmax) of Emiliania huxleyi (Lohmann) Hay et Mohler is known to be carbonlimited at natural concentrations of dissolved inorganic carbon (DIC). In the present study, light-limited and light-saturated photosynthetic rate

The fccal pellet production of Abra alba was measured during exposure to different concentrations of diesel oil, drilling muds with different base fluids, oil-based cuttings and barite. For oil-based drilling muds a curvilinear regression ( y = ax +

Mature Mytilus edulis were exposed to copper (concentration range 1–40 μg l ) and microencapsulated diesel oil (concentration range 200–5,000 μg l ) for 30 days and induced to spawn. EC 50 values for spawning frequency were approximately 2 μg

The carotenoid composition is reported of the ichthyotoxic phytoplankton Chrysochromulina polylepis (Prymnesiophyceae), grown in pure cultures. Carotenoid yields correspond to ca 1 mg/20 I culture. The carotenoid composition consisted of (3S, 5R,6S,3

Heritabilities are estimated for growth in shell length in larvae and juveniles of Mytilus edulis, based on a nested design, involving 27 families (27 females, 9 males). Very high heritabilities (hD2 > 0.6 and hS2 > 0.5) were found for growth in both

Shell-length growth is measured several times in 5–7 wk of temperature exposure during spring (12–20 °C) and autumn (8–20 °C). The acute response to temperature exposure is an increase in shell-length growth with temperature. During the accli
