Macroalgae can incorporate the isotopic signature (δ 15 N) of their external environment
and be used as 'bioindicators' to map and identify between multiple sources of
anthropogenic nitrogen. However, evidence suggests that the isotopic signature of their
tissues can also be influenced by a range of other factors, which could confound their use as
a monitoring tool. Hence, this study aimed to better understand the factors affecting
macroalgae isotopic signatures, using Chondrus crispus as a model species. This was …
