Molecular Characterisation of Natural Organic Matter in Lacustrine Systems

Autochthonous production sustains food webs in large perialpine lakes, independent of trophic status: Evidence from amino acid stable isotopes

“…Replicate measurements across laboratories can differ significantly, e.g., see Stücheli (2018) with an interlaboratory offset of −0.6 ± 1.6‰ using external samples. Although it is hard to tease apart differences due to different species or phyla, it appears that some studies had consistent C fingerprinting offsets (e.g.…”
