Density of amphibian tail fin, and conversion into the fin surface required to produce 100 μg of freeze-dried matter (i.e. the minimum mass required for nitrogen-rich biological material for stable isotope measurements).
|Species||Number of individuals||Freeze-dried matter density (µg mm−2)||Fin surface required (mm−2)|

|Agile frog||17 (62)||13.7 ± 4.7||6.9–22.7||9.0 ± 2.8||5.5–16.7|
|European tree frog||10 (39)||7.9 ± 2.4||5.1–12.4||14.4 ± 4.1||9.0–20.8|
|Marbled newt||29 (139)||55.3 ± 9.1||23.1–89.4||2.0 ± 0.4||1.0–4.4|
|Palmate newt||7 (23)||37.7 ± 4.2||25.4–62.2||3.0 ± 0.2||1.8–4.0|
