Hair mineral levels as indicator of wildlife demographics?:a pilot study of muskoxen
The tight linkage between mineral status and health and demographics in animals is well documented. Mineral deficiencies have been coupled to population declines in wildlife. Current practices typically rely on liver, kidney and/or serum samples to assess mineral levels. Such destructive sampling st...
