    Status, Issues, and Challenges of Biodiversity: Marine Biota
    (Springer Nature, 2022-09-15T00:00:00) Yadav, Digvijay Singh; Rani, Alka; Dubey, Sheetal; Bast, Felix
    India is one of the mega biodiversity countries, owing to its tropical location and warm climate. With more than 7500 km, India is blessed with a long coastline-one of the longest in the world. However, marine biodiversity remains poorly documented compared with that of terrestrial biodiversity. On top of it, the threats from climate change are imminent and have already started wreaking havoc on species diversity, for instance, ocean acidification causing coral bleaching in the atolls of the Laccadive Islands. A systematic approach to acquiring complete and exhaustive knowledge about marine biodiversity may help us understand the extent of anthropogenic damage and take appropriate actions and policies to prevent further loss. Currently, we merely know the tip of the global biodiversity iceberg; with merely 1.3 million species characterized yet, estimates suggest there might be around 9 million species of eukaryotes alone. Conserving biodiversity is crucial not only for ecosystem services but also for future generations as a possible revenue generator-the so called bequest value. This chapter reviews the status of marine biodiversity along India�s coasts, efforts on its economic utilization, and the impact of climate change. � Indian National Science Academy 2022.

    Arctic biodiversity amidst looming climate apocalypse: Current status and way forward
    (Elsevier, 2021-08-27T00:00:00) Rani, Alka; Gupta, Kriti; Saini, Khem Chand; Narwal, Sahil; Bast, Felix
    Arctic region is at the forefront of climate crisis; this is where the planet is warming maximally and the effects of climate change are most obvious. In this review, we introduce the topic in broader perspective by discussing first on why Arctic biodiversity matters, and scientific evidences for a changing Arctic biodiversity due to climate change. The Arctic then dwells into the current status of Arctic biodiversity covering species diversity and its conservation status with an emphasis on species important for bioprospecting. Subsequently, threats to Arctic biodiversity will be reviewed including climate change, shipping, oil exploration, overfishing, and overharvesting. This essay would then further deliberate why Arctic matters to India in particular. Himadri-Indian research station at Svalbard, Norway-will be briefed followed by an overview of Svalbard Global Seed Vault and why signing a pact with this international facility would benefit the country. The essay concludes with final thoughts and way forward including strategies to minimize Arctic biodiversity loss, UN SDGs (Ssustainable Ddevelopment Ggoals), and climate action. � 2021 Elsevier Inc.
