A high-density brown bear population on the Shiretoko Peninsula, Japan, was found to have between 128 and 173 breeding females and 66 and 91 breeding males, with a minimum total population size of 449 individuals in 2019. This estimate was derived using DNA-based pedigree reconstruction, which relied on long-term genetic sampling (1998–2020) followed by intensive noninvasive surveys (2019–2020). Researchers successfully assigned parentage for 330 bears and partial parentage for an additional 123 individuals using microsatellite markers. The study demonstrates that combining extensive historical data with short-term intensive sampling can yield reliable demographic estimates for elusive species, providing critical insights for conservation efforts.

A significant linear decrease in canopy Leaf Area Index (LAI) and Normalized Difference Vegetation Index (NDVI) with increasing altitude was observed in Sri Lankan tropical rainforests, highlighting the impact of elevation on forest structure. The study found that LAI decreases by 0.396 units per 1,000 meters of altitude rise, with second-order polynomial functions providing a better fit for data than linear models. Two predictive models were developed using NDVI metrics and canopy architectural properties, achieving adjusted-R² values up to 0.544. The research utilized hemispherical photography and satellite imagery from Landsat 8 to analyze LAI and NDVI across seven forest reserves spanning altitudes from 117 to 2,132 meters.

Research demonstrates that Formosat-5 (FS5) satellite images can effectively estimate total suspended matter (TSM) concentrations in coastal waters, including UNESCO World Heritage Site Ha Long Bay, Vietnam. The study developed a linear regression model to correct atmospheric effects in FS5 data by comparing it with Landsat-8 OLI reflectance, achieving high accuracy (R²: 0.87–0.96). Applying existing TSM algorithms to the corrected FS5 images yielded results comparable to those derived from OLI (R²: 0.86–0.95) and validated against in situ measurements. Cross-comparisons with OLI-derived TSM data confirmed the reliability of FS5 for coastal water monitoring, offering a cost-effective alternative for high-resolution TSM estimation.
