Diel colour changes in male Sapphirina
nigromaculata (Cyclopoida, Copepoda)
We are delighted to welcome to our Biosciences seminar series a visitor from The University of Tokyo, Prof Kazutaka Takahashi. Kazutaka is based at the Department of Aquatic Bioscience at the Graduate School of Agricultural and Life Sciences. Kazutaka has a keen interest in zooplankton dynamics, especially the ecology, behaviour and physiology of copepods.
apparent contradiction, we conducted detailed observations of colouration patterns in Sapphirina nigromaculata, which has been previously described as both iridescent and non-iridescent.
The synchronization of iridescence in concert with upward migration is considered to be an adaptation for increasing the likelihood of encountering a mate. Observations using a video plankton recorder revealed that the transparent phase is an adaptation for decreasing predation risk by making the copepods more difficult to distinguish while they are associated with doliolids.
Hope to see many of you - everyone most welcome to attend!
