About Kristie Rigby
PhD Student in the Signals in the Sea group. My main research interest is to explore the chemical signalling between zooplankton and phytoplankton. More specifically the signals from marine copepods, which are known to produce a group of polar lipids known as copepodamides. Copepodamides are known to initiate defensive characteristics in various phytoplankton. From previous studies, we know that phytoplankton sense copepodamides and respond with defensive traits such as toxin production, altered swimming behaviour, increased bioluminescence and splitting of colonies. As a wide variety of phytoplankton respond to copepodamides, these predator cues may aid in the structuring of plankton communities. By using behavioural, ecological and biochemical perspectives I aim to understand the role of the copepodamides in nature to better understand the links between predator and prey.
