Biography

Jessica completed her Ph.D. in Biological Oceanography at the GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany. Her Ph.D. thesis “Climate change effects on zooplankton body size: a range of experimental approaches” included experimental work with natural plankton communities using mesocosm experiments to investigate multiple and interacting environmental factors, temperature, ocean acidification and nutrient balance. Jessica found that interacting temperature and pH changes affect species- and age-specific zooplankton body size and community abundance. Further, she was able to identify that warming and ocean acidification leads to changes in the fatty acid profile in zooplankton and reduced fitness using RNA/DNA ratio. She also worked on how temperature and food chain length affects the net primary production and respiration of ecosystems extending the Metabolic Theory of Ecology in collaboration with Dr. Mary O’Connor (UBC). She has presented and published her work in international conferences and journals.
