My master´s thesis will be about the change in the diet of kittiwakes over time. With incoming Atlantic waters, Atlantic species comes further north. I will investigate how the energy content of available food/prey changes with changing species ranges. I will be taking part in the field work in Kongsfjorden, which will give me insight in the methods used to obtain these dataseries. We will collect diet samples from the birds as well as blood samples. These data will contribute to the existing timeseries and will be used in several projects.
