Community structure of intestinal adult trematodes (Platyhelminthes) in six species of Haemulon (Osteichthyes) in Puerto Morelos Reef National Park, Quintana Roo, Mexico

Haemulids (grunts) represent one of the most diverse families marine fishes. Even though haemulids are well represented in Mexico along Pacific and Gulf coasts, as Caribbean Sea, their trematode fauna has been scarcely studied. Here, 8 species Haemulon from Puerto Morelos Reef National Park (PMRNP), Quintana Roo were analyzed to describe composition patterns community structure at both, infracommunity component levels. Eleven trematodes gastrointestinal tract hosts identified. Overall, 16 new host records reported this study. Eight 11 PMRNP for first time. All considered rare species, with prevalence values < 20%. Species accumulation curves showed that 3 6 i.e., H. flavolineatum, plumierii, sciurus , reached an asymptote, only was analyzed. Communities species-poor dominated by a single low diversity Trematode communities differ among grunts study, indicating ecological factors such feeding habits, geographic distribution, vagility play major role structuring these communities.
