Abstrakt: Rampant urbanization in coastal environments turns areas close to the seafront into a highly impacted ecosystem, possibly affecting the health and well-being of resident animal species. The tuco-tuco Ctenomys flamarioni is an endemic and endangered subterranean mammal from southern Brazil, and the anthropic influence was considered one of the main threats to the species. In this context, the present study aimed to investigate the patterns of oxidative status of the species in natural areas with different levels of anthropogenic disturbance. We evaluated two populations of C. flamarioni, one located in an area with intense anthropogenic impact due to urbanization and tourist activity, and the other in a non-impacted area. Oxidative injury parameters (lipid peroxidation and carbonylated protein levels), and the activities of the antioxidant enzymes superoxide dismutase, catalase, glutathione peroxidase, glucose 6-phosphate dehydrogenase, glutathione S-transferase and carboxylesterase were measured. Individuals inhabiting the impacted area had lower G6PDH activity and higher levels of carbonylated proteins. This combination of higher level of oxidative damage and lower antioxidant activity is an indication that the oxidative status of animals in the impacted population is possibly being affected as a consequence of anthropogenic activities in this environment. The values of the parameters obtained in the current study can be used as a reference of the oxidative state of C. flamarioni in future studies with tuco-tucos.
