Sarah E. Hobbie. 2008. Nitrogen effects on litter decomposition: a five-year experiment in eight temperate sites. Ecology 89:2633–2644.

Appendix B. A table showing results of ANCOVAs for each site–substrate combination of the proportion initial N at all harvests with N fertilization as a main effect and the proportion initial mass remaining as a covariate.

TABLE B1. A table showing results of ANCOVAs for each site–substrate combination of the proportion initial N at all harvests with N fertilization (N) as a main effect and the proportion initial mass remaining (MR) as a covariate. When MR was significantly related to proportion initial N, the relationship was positive except where indicated (-).
