Figure 1

Isotopic biplot of the benthic community (a) before (November–December 2016) and (b) after (January–February 2017) sea-ice breakup in Tethys Bay (Terra Nova Bay, Ross Sea). Each point represents a specimen. Full symbols represent basal food sources, empty symbols represent consumers. The isotopic space is divided into ITUs (Isotopic Trophic Units, i.e. 1 × 1‰ intervals of δ15N and δ13C) in accordance with Rossi et al.9. Dashed-red line polygons delimit the convex hull (Total Area) of consumers. For the detailed list of species contributing to each sediment fraction, refer to Tables S1 and S2.
