Abstract
This study shows that recent global analyses using the Tea Bag Index (TBI) are influenced by methodological flaws: (1) the interdependence of stabilisation factor (S) and decomposition constant (k) biases correlation analysis, (2) derivation of S and k from separate decomposition curves causes their decoupling, and most importantly, (3) the determination of k is inaccurate.
期刊介绍：
Ecology Letters serves as a platform for the rapid publication of innovative research in ecology. It considers manuscripts across all taxa, biomes, and geographic regions, prioritizing papers that investigate clearly stated hypotheses. The journal publishes concise papers of high originality and general interest, contributing to new developments in ecology. Purely descriptive papers and those that only confirm or extend previous results are discouraged.
