A common error in calculating density of invertebrates in sediment core sections of unequal lengths
Ryszard Kornijów and Krzysztof Pawlikowski

The study shows that for sediment core sections of unequal lengths (which is frequently the case because researchers expect higher variability in the surface layers compared to the deeper ones), the only correct approach is to express all density measurements per unit volume (not area). Given the high number of studies using incorrect calculations, the study paves the way for better practices in benthic sampling.
