Field and GIS based post-tsunami assessment of Scleractinian coral cover in the Aerial Bay group of Islands, North Andaman, India

Coral Reef Health Status versus Muricid Bioindicator in the Lakshadweep Archipelago – A Multivariate Approach

“…Island ecosystems possess pristine environmental characteristics; human influence poses a serious threat to the fragile and susceptible biological processes on the islands (Sahu et al, 2013;Jha et al, 2015). Isolated oceanic islands support a highly sensitive and fragile coral reef ecosystem that offers unique possibilities to study the ecological changes and consequences that come with human settlement (Jha et al, 2011;Connor et al, 2012;Jha et al, 2013). Coral reefs are vital and core economic assets for any country that lies in the tropical and sub-tropical marine environment.…”

Comparative evaluation of heavy metal concentration in different organs of the asian seabass: A multivariate approach

“…India's coastal ecosystems have been severely damaged in recent years as a result of increased urban and industrial development (Dheenan et al, 2014;Dheenan et al, 2016;Yuvaraj et al, 2018;Jha et al, 2022). The contaminants that originate from these anthropogenic actions have the potential to negatively impact various ecosystems such as corals (Jha et al, 2011;Jha et al, 2013a), mangroves (Das et al, 2014), and the ecological health and functioning of coastal regions (Pandey et al, 2022) as well as estuaries (Pandey et al, 2021). Previous studies have also shown that the areas subjected to minimal human interference generally contain better seawater quality (Jha et al, 2012;Jha et al, 2013b;Jha et al, 2015).…”

Occurrence of Euryhaline Dunaliella salina in Andaman & Nicobar Islands: Assessment and Optimization of its Total Carotenoid by Orthogonal Array Design

“…A & N has a moderate climate with a temperature ranges from 23 to 31°C but with relatively high humidity (70 to 90 %) coupled with heavy rainfall approximately more than 318 cm/year (http:// www.imd.gov.in/pages/main.php). A & N island holds 40% of coral reef coverage of entire Indian coastline, provides shelter for diverse marine creatures 11 . The present study aims at the quantification and optimization of carotenoid production in the marine microalgae D. salina by Taguchi statistical tool for enhancing the total carotenoids production after identification by 18S rDNA sequencing.…”
