[NEWS] Contaminants in Colonial Waterbird Eggs – Wood Buffalo National Park

Description:

監測海鷗和燕鷗蛋中的污染物是深入了解當地環境條件的有用工具,因為海鷗和燕鷗是食物網中較低水平的過程的集成者,而且它們的蛋通常是用當地食物來源形成的。 因此,雞蛋的化學成分將反映飼養菌落附近區域的化學特徵,包括汞等污染物的含量。

Monitoring contaminants in gull and tern eggs is a useful tool for gaining insights into local environmental conditions because gulls and terns are integrators of processes occurring at lower levels in the food web and their eggs are generally formed using local food sources. Therefore, the chemical composition of the egg will reflect the chemical characteristics of the region in the vicinity of the breeding colony, including level of contaminants, such as mercury.
