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 ). WebMay 21, 2024 · The sum of the biomass of these phyla represents our estimate of the total biomass of animals. We give estimates for most phyla and estimate bounds for the …

Biomass Estimation Methods for Tropical Forests with Applications …
WebFor total, aboveground, and belowground biomass estimation, methods 1, 2, 4, and 5 were found to be in the group of unbiased estimators, while methods 3 and 6 were in the class of slightly biased estimators. The unbiasedness or slight bias occurred independently of the sample sizes studied. Within each group, the same estimates were obtained. WebThe biomass is the mass of living biological organisms in a given area or ecosystem at a given time. Biomass can refer to species biomass, which is the mass of one or more species, or to community biomass, which is the … WebMar 29, 2024 · Subsequently, we employed linear and non-linear regression models to estimate LAI and biomass. The correlation analysis indicates that GRVI derived LAI and biomass have the lowest RMSE and high R2 values compared to CpRVI and DpRVI. The DpRVI in VV-VH mode also provided promising accuracy for these biophysical … birthstone for february 14
