Hazard and Risk of Anticoagulant Rodenticides to Predatory and Scavenging Wildlife

Invasive mammalian predators are the most damaging group of animals affecting global biodiversity.  When introduced on remote islands, alien rodent species can devastate local biota and have been linked to approximately 30% of all extinctions. In addition, rodents can also consume and spoil crops, and serve as disease vectors that affect humans.  Starting in the 20th century,...
