Impacts of host phylogeny, feeding styles, and parasite attachment site on isotopic discrimination in helminths infecting coral reef fish hosts

Abstract: 27Stable isotopes of carbon and nitrogen characterize trophic relationships in predator-prey 28 relationships, with clear differences between consumer and diet (discrimination factor, Δ 13 C, 29 Δ 15 N). However, parasite-host isotopic relationships remain unclear, with Δ 13 C and Δ 15 N 30 remaining incompletely characterized, especially for helminths. In this study, we used stable 31 isotopes to determine discrimination factors for 13 parasite-host pairings of helminths in coral 32 reef fish. Δ 15 N differen… Show more

“…5, 6) that is likely not solely a result of feeding style differences. These large variations in Δ 15 N values between relatively closely related parasitic species has been observed previously (Riekenberg et al 2021a). They are not unique to nematodes as Deudero et al (2002) found that different species of parasitic copepods on the same host exhibited very different δ 15 N values.…”

“…Several mechanisms potentially contribute to variability in TDFs for parasitic relationships: 1) mismatch between measured tissue type and tissue use by parasite, 2) incorporation of multiple materials depending on parasite feeding style and 3) differing abilities in directly acquiring, anabolizing or metabolizing amino acids between parasites (Riekenberg et al 2021a). Many studies examining parasite-host isotopic differences used host muscle tissue despite local parasite attachment to or inhabiting another organ or tissue.…”

“…5 & 6) that is likely not solely a result of feeding style differences. These large variations in Δ 15 Ν values between relatively closely related parasitic species has been observed previously (Riekenberg et al 2021) and are not unique to nematodes as Deudero, Pinnegar and Polunin (2002) found that different species of parasitic copepods on the same host exhibited very different δ 15 N values. Atypical 15 N enrichments in parasites may potentially be explained by metabolic processes unique to each parasite taxon and Kamiya et al (2019) and Thieltges et al (2019) indicated Δ 15 Ν variations in parasite-host pairings may be related to parasite phylogenetic histories.…”
