Heliodiaptomus viduus Morphometric, Truss-Network, Statistical and COI Supporting Data

This dataset contains the supporting data for the study “When Shape Meets Sequence: Geographic and Sexual Variation in Heliodiaptomus viduus (Crustacea: Copepoda: Calanoida: Diaptomidae)”. The repository includes supplementary tables (S1–S20), morphometric, meristic and truss-network data, statistical analysis outputs, and original mitochondrial COI gel images supporting the morphological and molecular characterisation of Heliodiaptomus viduus collected from 18 localities across Madhya Pradesh, Haryana and Maharashtra, India. The dataset is intended to provide transparent access to the data underlying the published analyses and to facilitate reproducibility and future comparative research.
