Abstract

Ecologia da comunidade de helmintos gastrointestinais de tartarugas-verdes (Chelonia mydas) recolhidas no litoral do Espírito Santo 4,29 ± 2,19 (1-10) and the mean intensity of infection was 315,64 ± 281,83 (2-994)

Helminth Fauna of Juvenile Green Sea Turtles (Chelonia mydas) from Rio de Janeiro State, Brazil

“…The mean intensity was 536 (95% CI = 362 -853) (range: 1 -2831), the mean abundance was 536 (95% CI = 364 -850), and the species richness was 7.86 (95% CI = 6.46 -9.21) (range: 1 -17). The present study reports the highest prevalence, mean intensity of infection and species richness when compared to other studies on juvenile green sea turtles in Brazil Binoti et al, 2016;Gomes et al 2017). The present results were also similar to those found in adult females of green sea turtles studied in Costa Rica (Santoro et al, 2006).…”

“…The present results were also similar to those found in adult females of green sea turtles studied in Costa Rica (Santoro et al, 2006). This finding together to different component community than previous studies Binoti et al, 2016;Gomes et al 2017) suggest that the northern region of the state of Rio de Janeiro could have different environmental conditions that make richer the parasite fauna of the juvenile green sea turtles. That in the study area there is the coastal upwelling system with the highest intensity of the Brazilian coast (Coelho-Souza et al, 2012).…”

“…Cricocephalus albus was the most prevalent species (89.3 %), followed by M. invaginatum (82.1 %), P. obliquus (82.1 %), and R. uterocrescens (53.6 %). Similar results were observed from the coast of the state of Espírito Santo (northernmost state) (Binoti et al, 2016;Gomes et al, 2017), and from São Paulo (southernmost state) and the south of the state of Rio de Janeiro . Sixteen (57 %) carcasses were in poor body condition; the remaining turtles were in good or fair condition.…”

“…In Brazil, there are still few studies detailing on the parasite fauna of juvenile stages of sea turtles. Only recently, in the state of São Paulo and south of Rio de Janeiro, and Binoti et al (2016) and Gomes et al (2017) in the state of Espírito Santo investigated the parasite fauna of juvenile green sea turtles. Aiming the fulfi llment of knowledge gaps in the fi eld, we report the gastrointestinal parasite fauna of juvenile green sea turtles from the coast of Rio de Janeiro, Brazil.…”
