ABSTRACT
Diatom frustules have been found to play a vital role in corroborating evidence, emphasizing the need for morphological studies. Hence, the present study was aimed at comparing the seasonal variation in diatoms in the Ganga and Yamuna rivers of Delhi. The phytoplankton study observed that diatom identification based on the valve view was comparatively easier and can be matched with known databases. However, identification becomes challenging when examining the girdle view of diatoms. To address this issue, a comprehensive study of the girdle views of diatoms from the Ganga and Yamuna rivers was conducted during the years 2021-22. The findings of this study provide valuable insights for scientists, experts and researchers working in the field of forensic diatomology and other related areas, aiding them in the identification of diatoms based on their girdle view.
