4.2 Improve understanding of basic life history of Arctic marine species to support multi-agency decision-making.

Life history data are fundamental to understanding existing relationships in ecosystems, potential feedback loops, and anticipating biological responses. This effort will benefit from engaging with Indigenous subsistence communities through co-management agreements and community meetings because biological sampling of organisms harvested by subsistence hunters provides efficient and cost-effective access to information that might not be otherwise available to several Federal agencies. Many of these projects are conducted in collaboration with State agencies and nongovernmental collaborators. 

Performance elements from the Arctic research plan

  • 4.2.1 Assess feeding ecology of Arctic species and fill seasonal data gaps. One such project will identify walrus prey based on an innovative approach using molecular markers.
  • 4.2.2 Determine basic life history information on age and growth rates of key links in the food web.
  • 4.2.3 Assess the value of recent interdisciplinary programs and synthesis efforts to guide management decisions and allocation of resources.
