length_to_mass: Converts length measures to body mass for bees and Carabids

Description Usage Arguments Value Examples

Description

For Bees, the conversion is done as per Cane et al. 1987 (Estimation of bee size using intertegular span (Apoidea). Journal of the Kansas Entomological Society 60:145–147). The correlation between IT and body mass is 0.96. For Carabids the conversion is done from Jelaska et al. 2011 (Carabid beetle diversity and mean individual biomass in beech forests of various ages. ZooKeys 100:393-405) which in turn is based on Szyszko J (1983) book.
