Estimates <strong>of</strong> mean wood and leaf supply rates, macroinvertebrate production, and<br />
crayfish demand in Hering, Limrock, and Tony Sinks caves. All values are g ash<br />

Estimates <strong>of</strong> biomass (g ash -ree dry mass [AFDM] m -2 ), production (g AFDM<br />
m -2 yr -1 ) and production:biomass ratios (P:B) from surface and cave crayfish<br />
populations. Dry weight was assumed to be 30% <strong>of</strong> wet weight and AFDM as<br />
64% <strong>of</strong> dry mass. <strong>The</strong> AFDM conversion factor was estimated using data from<br />
