Denoting or involving a period of twenty-four hours:tidal and diel cycles...
Two additional cruises were conducted during calm periods to determine diel variation in the vertical distribution of C. concholepas competent larvae.
Water movement and diel cycles of internal water distribution between water-storage hydrenchyma and photosynthetic chlorenchyma has also been demonstrated for A. deserti, Ferocactus acanthodes and Opuntia ficus-indica.
Specimens were collected over a broad range of times to ensure that foods consumed throughout the diel cycle were represented.
