Diatoms as Indicator Tool for Climate and Environmental Changes and Research Imperatives for Tropical Asia
Journal Title: International Journal of Oceanography & Aquaculture - Year 2018, Vol 2, Issue 2
Abstract
Diatoms are microscopic autotrophic algae belonging to the Bacillariophyceae class. They may be planktonic, benthic, and epiphytic or epipelic etc., found in a wide range of habitats - freshwater, marine water and oceans. Their size ranges from 2 microns to several millimeters. Due to a silicified body wall, diatoms are preserved for long epoch of time as fossil forms. The fossil evidence shows that these tiny organisms originated close to Permian-Triassic boundary 250 Mya and the estimated number of extinct and extant diatom species may well be over 50.000 [1].
