Primary production in the Arctic Ocean: Winners and losers of a rapidly changing icescape

C.J. Mundy (Biological Oceanographer, Associate Professor Chair, Graduate Studies Committee Centre for Earth Observation Science Department of Environment and Geography Clayton H. Riddell Faculty of Environment, Earth, and Resources University of Manitoba)
The Arctic is warming at twice the rate of the rest of the world. This change
is manifesting through a declining ice cover (aka icescape) with important
implications on the marine ecosystem. At the base of the food web, primary
producers fix the sun’s energy during a short bloom season into organic
matter that sustains the marine ecosystem throughout the year. In my POS
talk, I will discuss Arctic primary producers and how change is impacting the
system.

Paradoxically, lemmings also seem to be attracted to dens of Arctic foxes, their major predators. We found by fertilizing their dens through excrement and prey remains, Arctic foxes create local hotspots of productivity on the tundra, as enriched soils stimulate plant growth that attracts wildlife.
