Stable isotope analysis is used to investigate the trophic ecology of organisms and, in order to use samples from archived collections, it is important to know whether preservation methods alter the results. This study investigates the long‐term effects of four preservation methods on isotopic compositions and isotopic niche parameters of sea stars.
