Short summary

We determined the isotopic composition of chlorophyll a in periphytic algae attached to a streambed substrate (periphyton). Although the bulk isotopic composition of periphyton is recognised as a surrogate for the photosynthetic algal community, our results indicate that the bulk periphyton matrix at the study site consists of 89 to 95% algal carbon and 5 to 11% terrestrial organic carbon. We show that the chlorophyll a isotopic composition is a useful tracer for the aquatic food web studies.
