Nutritional quality of prey influences consumer communities including their nutritional quality, so shifts in nutrition at the food web base can be transferred up the food chain to affect fish, seabirds, and mammals. \u00a0Zooplankton are the main link between primary producers and higher trophic levels, and display variable nutrition based on their taxonomy, prey sources, and physical environment. Therefore, zooplankton nutritional quality and its drivers are key to understanding how nutrition influences pelagic food webs. One component of nutrition, essential fatty acids, must be obtained by consumers through their diet. They are produced at the base of the food web by phytoplankton, bacteria, and protists, and are passed on to consumers, leaving a tracer of the food sources that support higher trophic levels. Using time series from the northern Strait of Georgia, I investigate variation within, and connections between, particulate organic matter at the food web base and zooplankton consumers across seasonal and inter-annual time scales. Shifts at the base of the food web influence the prey consumed by zooplankton\u2014causing changes to their trophic resources and nutritional quality for predators.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n

Dr. McLaskey is a zooplankton ecologist and biological oceanographer who researches the lower trophic levels of marine food webs\u2014from phytoplankton, through zooplankton, to fish. She\/they grew up on San Juan Island, WA and joined the Pelagic Ecosystems Lab at IOF in 2019 after completing her\/their PhD at the University of Washington. In graduate school, she\/they studied the effects of ocean acidification and hypoxia on zooplankton, using a combination of experiments and field work. Now much of her\/their research focuses how ocean conditions affect food web structure and nutritional quality, including a new project on thiamine deficiency in Chinook salmon and the potential food web drivers of low thiamine in BC food webs.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
