Combined effects of agricultural activity and parasites on biomarkers in the bullfrog, Rana catasbeiana
چکیده انگلیسی

Agricultural contaminants can have devastating impacts on amphibian survival and development, particularly considering their sensitivity to environmental perturbation. However, it is commonly overlooked that amphibians are infected with various parasites that can influence the overall health of the animal when exposed to a stressful environment. We investigated the interaction of agriculture and parasitism on the health of bullfrogs (Rana catesbeiana) in the field. Nine physiological and immunological biomarkers were related to naturally acquired parasite infections, along a gradient of agricultural activity. Most health biomarkers were affected by agriculture, parasitism, or both. Although bullfrogs residing in agricultural areas were infected with fewer parasite species, reflecting environmentally compromised ecosystems, certain persistent parasites interacted with agricultural disturbance to alter the physiology and immune competence of bullfrogs. The consequences of the combination for animal health highlight the importance of parasitism in ecotoxicological studies. Consideration of parasitism is warranted when evaluating the influence of anthropogenic disturbance on amphibian declines and environmental health.
