Understanding the effects of pesticide exposure on organisms throughout their life cycle is critical to predict population-level effects. For many taxa, including amphibians, juveniles are the main dispersal stage and are disproportionally important to population persistence when compared with other life stages. In the present study, we examined the effects of a single 24-h exposure to the insecticide carbaryl or the herbicide atrazine on locomotor performance (endurance, distance traveled, speed, and fatigue) in the laboratory and terrestrial growth and survival through overwintering in field enclosures using recent metamorphs of spotted salamanders (Ambystoma maculatum). We found that neither atrazine nor carbaryl impacted endurance, but fatigue increased with carbaryl exposure, which could leave salamanders less able to escape repeated attacks by predators. Terrestrial growth and overwinter survival were not affected by short-term exposure to carbaryl or atrazine, suggesting that when individuals can overcome acute effects, no long-term consequences result for the endpoints measured.
