ABSTRACT:
The coati (Nasua nasua, Linnaeus 1766) is a generalist species, feeding on often-discarded human food in dumpsters around ecological tourism sites. We investigated the body weight and some blood chemistry variables related to the diet of wild coatis from three parks: Parque Municipal das Mangabeiras (PM), Parque Nacional do Caparaó (PNC) e Estação Ecológica Água Limpa (EEAL). We tested the plasma of 53 coatis for high-density lipoprotein (HDL), alanine transaminase (ALT), aspartate transaminase (AST), gamma-glutamyl transferase (GGT), cholesterol (Chol), triglycerides (Trig), and alkaline phosphatase (ALP). Male and female adults did not significantly differ on the weight (P > 0.05) and blood chemistry indexes (P > 0.05). The adult coatis of the PM were heavier than the adult coatis of the other two parks. There were significant differences in HDL (P < 0.04), AST (P < 0.001), ALT (P < 0.001), and GGT (P < 0.001) between adults of the three parks. Only ALT and ALP were significantly different (P < 0.05) among the young coatis. The results suggested the coatis of the three parks have different health status. The consumption of discarded human food seems to affect body weight of the PM coatis. The coatis from PNC and EEAL had blood chemistry profiles suggestive of liver disorder. We recommend carrying on environmental education programs to visitors and additional clinical investigations on coatis from these parks.
