Short-term tissue decomposition alters stable isotope values and C:N ratio, but does not change relationships between lipid content, C:N ratio, and Δδ13C in marine animals
Fig 2
Significant relationships between (a) lipid content and Δδ13C (b) C:N ratio and lipid content and, (c) C:N ratio and Δδ13C of fish muscle tissues were not affected by exposure to air or ice over 120 h. Per (a), (b) and (c), modelled slopes and raw data for each exposure time (0, 60 and 120 h) in air (red lines) and ice (blue lines) are shown, although they do not significantly differ from one another. Model estimates of slopes, intercepts and model variance explained (R2) are also given.
