Accounting for food availability reveals contaminant-induced breeding impairment, food-modulated contaminant effects, and endpoint-specificity of exposure indicators in free ranging avian populations
It remains unclear how sub-lethal effects of contaminants play out in relation to other stressors encountered by free-ranging …
