Research interests

Specialisms: Gelatinous zooplankton, jellyfish blooms, zooplankton

Dr Lucas has published 39 articles and 3 book chapters in peer-reviewed literature. She has produced a new book “Jellyfish Blooms” Pitt KA & Lucas CH (eds), Springer, which has been published as an e-book in 2013 and in hard copy in 2014.

I have a broad interest in coastal and estuarine processes, in particular the interaction between biological communities and the environment, and how ecosystems function and respond to change. My main research focus is the biology and ecological role of jellyfish in pelagic food webs, in particular studies of the population dynamics, trophic impact and reproductive biology of UK species. Current research projects are focusing on the magnitude, causes and consequences of jellyfish blooms around the globe; polyp ecology and the roles of asexual and sexual reproduction in forming and maintaining jellyfish populations; phenotypic differences between populations of Aurelia; causes of, and problems associated with jellyfish stranding on beaches; and the macro-ecology of mesopelagic jellyfish.
