Element concentrations in tissues reveal spatial structure of Atlantic walrus management stocks
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.Differences in tissue element concentrations confirm geographic differentiation between 2 of Canada's walrus management stocks but reveal additional spatial structure within the largest stock that may have management implications. Abstract Ensuring harvested animal populations are managed at appropriate scales requires an understanding of underlying ...
