Pesticide triggers a food chain cascade
A new study shows how sublethal concentrations of malathion can indirectly hurt frog populations by altering the food chain in aquatic ecosystems.
When it comes to pesticides’ effects on frogs, sublethal concentrations do not preclude lethality. That’s the conclusion of a new study published in the October issue of the journal Ecological Applications. After dosing wood frogs and leopard frogs with very small concentrations of the popular pesticide malathion, the researchers discovered that the chemical did not kill the frogs directly—instead, they died from the indirect effects of the pesticide ...
