The trophic structure of a pipefish community (Pisces: Syngnathidae) from a western Mediterranean seagrass meadow based on stable isotope analysis

2004

Syngnathus abaster and S. typhle (Pisces. Syngnathidae) from a dense Cymodocea nodosa meadow in the western Mediterranean Stagnone di Marsala (Italy) were studied using δ13C and δ15N analysis. Because of the presence of these two species in the same habitat and the specialized parental care by the male, the effect of species and sex on the isotopic composition was also studied to investigate the different feeding strategies between and within species. S. abaster and S. typhle exhibited enriched 13C and 15N values throughout the sampling period (δ13C mean ± s.e. = -10.5 ± 1.8‰ and -10.8 ± 2.0‰, δ15N mean ± s.e. = 11.9 ± 0.7‰ and 10.6 ± 1.0‰ respectively), suggesting that these species receiv…
