Sylvain Coq, Jean-Marc Souquet, Emmanuelle Meudec, Véronique Cheynier, and Stephan Hättenschwiler. 2010. Interspecific variation in leaf litter tannins drives decomposition in a tropical rain forest of French Guiana. Ecology 91:2080–2091

Appendix B. Structural information on tropical litter condensed tannins.

TABLE B1. Structural information on tropical litter condensed tannins, for extractable (Extract.) and non-extractable (Non-extract) condensed tannins and remaining litter mass after 312 days of field exposure (N = 4 for each species), with (coarse mesh litterbags) and without (fine mesh litterbags) animals. Percentage (%) gallate represents the percentage of epicatechin gallate monomers; percentage Prodelphinidin represents the percentage of prodelphinidin and percentage cis represents the percent cis stereochemistry at C-2–C-3.
