PhD project title:

Small copepods in high latitudes.

PhD project description:

My PhD will focus on different aspects of the zooplankton population dynamics in the high latitude ecosystems, with emphasis on the small copepod group. My interest is to comprehend their seasonal variation and ecological importance. For that purpose, I will use a combination of both field and laboratory studies to enlarge the shortage of information available for small copepods in the Northern waters.

Start date: May 2015

PhD Project title:

Reproduction in Polar Cod: a study of the potential effects of anthropogenic activity on the reproductive success of an Arctic keystone species.

PhD Project description:

The first part of my study will primarily investigate reproductive strategy of polar cod, a keystone species in the Arctic ecosystem, and characterize physiological changes and reproductive development of polar cod in relation to their environment.  The second part will be expanded to a circumpolar scale as polar cod are found in every shelf sea of the Arctic, clearly demonstrating a successful strategy for Arctic domination. The ability of polar cod to reproduce during the cold, dark and food limited Arctic winter is believed to be a major factor in their success. This begs the question of how polar cod and their reproductive success will fair as the Arctic ecosystem is under pressure from climate change, human activities, and poleward moving competitors. This study will be focused in the Arctic and Atlantic influenced waters around Svalbard and expand to the American and Canadian Arctic waters.

An ecotoxicological component will also be included to explore the sensitivity of early life stages chronic levels of waterborne petroleum on important developmental checkpoints. This work expands upon two studies on adult polar cod sensitivity to acute and chronic exposure to crude oil, dispersed oil and burned oil residues.

Start date: September 2016
Planned submission date. June 2020
