Esteban R. Suárez, Timothy J. Fahey, Joseph B. Yavitt, Peter M. Groffman, and Patrick J. Bohlen. 2006. Patterns of litter disappearance in a northern hardwood forest invaded by exotic earthworms. Ecological Applications 16:154–165.

Appendix A (Table A1). Litter disappearance exponential rate constants (k, yr-1) for sugar maple and red oak litter samples in two exotic earthworm invasion fronts at Arnot Forest (central New York). At each invasion front, litter disappearance rates were estimated for earthworm-invaded areas, transition areas, and earthworm-free areas. For each model, the R2 value is shown in parenthesis.
