A dataset of individual wet weights of benthic macroinvertebrates
Limnology and Oceanography Letters, Volume 9, Issue 6, Page 696-715, December 2024.Abstract Biomass estimates are crucial for modeling and understanding energy flow through ecosystems. Many modeling frameworks rely on published body weights of organisms to convert density estimates to biomass. However, published body weight data are limited to few taxa in a limited number of systems. Here we present mean individual weights for common
