Factors associated with parasite dominance in fishes from Brazil

Abstract: The present study used regression models to evaluate the existence of factors that may influence the numerical parasite dominance with an epidemiological approximation. A database including 3,746 fish specimens and their respective parasites were used to evaluate the relationship between parasite dominance and biotic characteristics inherent to the studied hosts and the parasite taxa. Multivariate, classical, and mixed effects linear regression models were fitted. The calculations were performed using R softwa… Show more

“…Simpson index (D) was calculated to determine dominance trends among species of parasites, dominance being accepted when D > 0.25 (Daly, Baetens & De Baets, 2018). Relative dominance (RD) was estimated by the Berger-Parker index (Amarante, Tassinari, Luque, & Pereira, 2016). In ecological analysis, only species with a prevalence greater than 10% were included (Bush et al, 1997).…”
