Arctic Food Webs Ask A Biologist
As our planet's climate warms, its most rapidly changing region is the Arctic Ocean and surrounding seas. Warming causes many changes, including the melting of sea ice and a decline in the amount of water that is covered by ice. These changes impact organisms at every level of the food web.

Those animals got 20 to 50 percent of their dietary energy from algae that had been embedded in sea ice. The researchers described their findings July 8 in Limnology and Oceanography. Scientists have yet to look for markers of algae higher up in the food web — in bigger animals that may have dined on the zooplankton.

Feb 12, 2018. (Photo: Paul J. RichardsAFP/Getty Images) Scientists have pinpointed how crucial the microscopic algae that grow under and around sea ice are to the survival of polar bears, underscoring the ways in which climate change is upending the region's food web. As sea ice melts in the Arctic, multiple studies have documented the ice's.

The arctic II food web contains four poleward moving fish: cod (Gadus morhua), haddock (Melanogrammus aeglefinus) and two redfish species (Sebastes norvegicus and Sebastes mentella). The last two columns show the percentage difference for each food web metric between the boreal and the arctic (Diff B-A) food web and between the arctic II and.

A densely linked arctic food web. Many descriptions of arctic food webs have been focused on a relatively few vertebrate taxa (e.g., Summerhayes and Elton 1923; Krebs et al. 2003; Legagneux et al. 2012), but recent studies have exposed the diversity of arthropod nodes within these webs (Coulson and Refseth 2004; Jónsdóttir 2005; Fernandez.

In 2018, missing sea ice in the Bering Sea messed with the timing of the algal blooms, which make up the base of the region's food web. Cases of paralytic shellfish poisoning have increased seven-fold in Alaska over the past 40 years. The state now has one of the highest incidences of shellfish poisoning in the world.
