Comparison of rainbow trout diet models using the leave-one-out method, considering six possible sources with uniform or biomass prior assumptions, and using different TDFs.

OliV: Lumbriculus variegatus, OliT: Tubifex tubifex, OliH: Limnodrilus hoffmeisteri, Gas: Physa sp., Dap: Daphnia ambigua, Lep: Leptodiaptomus cuauhtemoci. TDF1 = (△δ13C = 0.49 ± 4.7‰, △δ15N = 4.43 ± 1.32‰), TDF2 = (△δ13C = 0.8 ± 1.1‰, △δ15N = 3 ± 2.6‰) [44, 45], TDF3 = (△δ13C = 0.91 ± 1.04‰, △δ15N = 3.41 ± 0.2‰) [46], TDF4 = (△δ13C = 1.85‰, △δ15N = 2.54‰) [41], TDF5 = (△δ13C = 2.8 ± 1.5‰, △δ15N = 5.14 ± 1.35‰) [15]. LOOic = Leave-one-out information criterion, se_LOOic = standard error of leave-one-out information criterion, dLOOic = difference leave one-out value compared with the best-fitted model, se_dLOOic = difference in the standard deviation of the leave-one-out value compared with the best-fitted model.
