WebMar 1, 2024 · Invertebrate biomass is considered one of the main factors driving processes in ecosystems. It can be measured directly, primarily by weighing individuals, but more often indirect estimators are used. WebJan 25, 2024 · A first approach based on structure from motion was used to generate a volumetric-based biomass estimation model (R 2 of 0.93 and 0.94 for fresh biomass [FM] and dry biomass [DM], respectively). This approach is not very sensitive to low vegetation levels but is accurate for FM estimation greater than 0.5 kg/m 2 (0.1 kg DM/m 2 ).
