Integrated Ecosystem Study

Outline
  • Seasonal
  • Broad scale
  • Trophic
  • interactions
  • People

4
Seasonal
  • Lower trophic level production
  • Fish winter survival

5
Seasonal Surveys
  • Abundance, bioenergetics
  • Biophysical moorings
  • Ocean conditions

6
Broad scale
7
Pollock ( ) respond to changes in ocean
temperature, as do fur seals ( )
Location matters

Scale
  • Prey abundance and quality
  • Foraging location
  • Reproductive success

10
Trophic interactions
Arrowtooth flounder abundance is increasing in
the Bering Sea
  • Piscivorous fish, birds and seals
  • Planktivorous fish and whales

11
People
  • Local and Traditional Knowledge
