Effects of ocean acidification on Antarctic marine organisms: A meta‐analysis

open access: yesEcology and Evolution, Volume 10, Issue 10, Page 4495-4514, May 2020., 2020
Antarctic waters are among the most vulnerable in the world to ocean acidification due to their cold temperatures, naturally low levels of calcium carbonate and upwelling that brings deep CO2‐rich waters to the surface. This meta‐analysis demonstrates groups of Antarctic marine biota in waters south of 60°S have a range of tolerances to ocean ...

First record of Okenia pellucid Burn, 1967 (Mollusca: Nudibranchia) from India

open access: yesJournal of Threatened Taxa, 2012
There are very few records of opisthobranchs in comparison to the vastness of Indian coasts. The published records are very patchy and limited to a few areas such as Gulf of Kutch, Gulf of Mannar, Lakshadweep and Andaman Nicobar Islands.
