Contemporary and afterlife effects on ecosystem processes.

NA – not applicable.Results of generalized linear models relating growing season biomass to decomposition rate (k) and nitrogen (N) and phosphorus (P) dynamics are shown. Contemporary effects are factors directly tied to leaf litter decomposition, and afterlife effects are pre-senescence plant traits that may indirect affect decomposition. Neighbor genotype identity is known to have a significant impact on all listed “biomass” factors. All data points are means (N = 16) of a genotype-neighbor genotype pairs (e.g., mean of genotype A1 grown with genotype G2). The slope is the parameter estimate that relates the factors to the ecosystem-level responses, and indicates a positive or negative relationship between the factor and response. Italicized, bolded values are significant at α = 0.05.
