GEOSPATIAL AND STATISTICAL ANALYSIS OF IRRAWADDY DOL-PHIN MORTALITY IN BANGLADESH (2000-2024) ⋆

This dataset contains geospatial and statistical analysis results from a comprehensive study of Irrawaddy dolphin (Orcaella brevirostris) mortality patterns in Bangladesh (2000-2024). The study analyzed 29 mortality events representing 135 dolphin fatalities using integrated spatial statistical methods including Ripley's K-function, Global and Local Moran's I, Getis-Ord Gi* hotspot analysis, and composite risk modeling. The dataset includes processed spatial data (shapefiles of mortality event locations, port infrastructure, protected areas, and river networks), statistical outputs (correlation matrices, temporal trend analyses), and conservation priority zonation maps identifying critical zones covering 96 km² that contain 49.6% of total mortality.
