PhD project title:
Biological responses in Arctic marine fauna: life cycles, resource use, and trophic links during a period of sea ice decline.
PhD project description:
The overarching goal of my thesis is to investigate how organisms respond to changing environmental conditions. How important are ice-derived food sources in Arctic food webs? And how relevant are these food sources during the polar night, a time of biological activity?
To answer these questions, I use a fatty acid and compound specific stable isotope analysis approach to estimate how primary producers (ice algae and phytoplankton) support various members within Arctic food webs.
In the face of wide-scale ecosystem changes in the Arctic Ocean, it is imperative to better understand how ice-associated species may potentially adapt to variable and changing ice conditions. Investigating how Arctic sea ice matters biologically during this time of ecosystem change will further support what is already known about this complex polar ecosystem.
