Table 3. Average (± standard error) of δ 13 C (‰) values for consumers and organic matter in the control and manipulation reaches post-litter addition in Bluff River Cave. Percent of consumer biomass composed of carbon from the amended corn litter as estimated from a standard linear mixing model (two-source, single-isotope). FPOM = fine particulate organic matter (≥250 to 500 µm). CPOM: C3 plants = coarse particulate organic matter (≥500 µm) that is only of C3 plant origin.
