There are errors in the eleventh and twelfth sentences of the Feeding Rate subsection of the Materials and Methods section. The correct sentence should be: This concentration was chosen to mimic a level close to that used in Edmunds [11], ca. 1.6 x 104 nauplii L-1, in order to provide corals with ad libitum access to zooplankton in order to see any potential differences in feeding due to therma...
In this study, the structure and ultrastructure of the digestive system are compared in the early larval stages (nauplii I and II) of two copepod calanoid species, Acartia clausi Giesbrecht, 1889 and Hemidiaptomus roubaui Richard, 1888. The nauplii I of both species have no functional digestive tract, which is represented initially only by a blind esophageal slit and yolky endodermal cells, whi...
The effects of sublethal concentrations of phenol and cadmium on the phototactic responses of the stage II nauplii of the barnacle Balanus amphitrite were investigated. Increased toxicant concentrations caused a reduction in phototactic responses. Balanus amphitrite nauplii exposed to nominal phenol concentrations of 100 ppm and higher for 1–12 h failed to exhibit phototactic responses, while l...
