Short‐term atrazine exposure at breeding has no impact on Blanchard's cricket frog (Acris blanchardi) reproductive success

Studies of endocrine‐disrupting contaminants have focused on early‐life exposures, but later exposures could impact fitness. We exposed adult frogs (Acris blanchardi) at reproduction to ecologically relevant atrazine concentrations (0, 1, or 10 µg/L) in outdoor arenas. We measured likelihood of bree...

Description
Summary:Studies of endocrine‐disrupting contaminants have focused on early‐life exposures, but later exposures could impact fitness. We exposed adult frogs (Acris blanchardi) at reproduction to ecologically relevant atrazine concentrations (0, 1, or 10 µg/L) in outdoor arenas. We measured likelihood of breeding and number of resulting tadpoles. Atrazine impacted neither the probability of breeding nor the number of tadpoles produced, suggesting anuran reproductive success may not be impacted by short‐term exposure to low concentrations.
