The life history of any given individual is defined by its ability to survive and reproduce over the course of its lifetime. Differences in life history traits can determine how animals acquire resources in the form of energy and allocate them towards different life history traits such as growth and reproduction. Most organisms store their energy within lipids and this becomes particularly important in the Arctic, where seasonal variation influences resource availability and energy utilisation. For example, during periods of limited prey availability, organisms may have to depend on internal energy reserves in order to sustain themselves through a winter season.

Energy release from lipid storages is especially important to consider when it comes to the bioaccumulation of contaminants. While some contaminants are associated with proteins, many contaminants are lipid soluble, including persistent organic pollutants (POPs).

A new pan-arctic study indicates that Calanus copepods do not necessarily descend deep for diapause in winter; instead, parts of the population remain active. Moreover, the deeper distribution of the larger and more conspicuous Calanus hyperboreus indicates that predation pressure is a key trigger for diapause at depth. In the central Arctic Ocean where visual predation pressure is lower, copepods might be relieved from the incentive to descend and can remain closer to the surface in winter.

For the final class of my Masters, I applied to Arctic Marine Molecular Ecology at the University Centre in Svalbard (UNIS). UNIS offers classes for undergraduate, graduate and postgraduate students in biology, geology, geophysics and technology. Once accepted, I booked tickets to the land of polar bears, northern lights, and the nautical polar night for an exciting five week educational adventure.
