Trace element concentrations and gastrointestinal parasites of Arctic terns breeding in the Canadian High Arctic
Baseline data on trace element concentrations are lacking for many species of Arctic marine birds. We measured essential and non-essential element concentrations in Arctic tern (Sterna paradisaea) liver tissue and brain tissue (mercury only) from Canada's High Arctic, and recorded the presence/...
