“…Additionally, the geochemistry of different rock types along the basin has been referred from several research studies. The nearby localities are explored by different researchers mainly (Narasimha and Kapfo, 2016;Babeesh , 2018). In the present work, V, Ni, Y, Ba are found to have higher values.…”

Heavy metal enrichment in urban soils demarcates a major ecological concern. The emerging industries, settlements and agricultural lands in bank of Kabini River resulted in prominent changes in water and soil geochemistry. In present work, a total of 20 soil samples from Kabini Basin have been checked for trace metals concentration and assessed following multivariate statistical approach. The PCA has been conducted to characterize the trace metals as per the common source of origin. The factors distinguished the heavy metals into 3 components with overall variance of 82.53%. Higher loading of various heavy metals indicates natural and anthropogenic interferences in soil. The baseline data generated from the present study provides the insight over the concentration of heavy metals, which would further be helpful in conservation and management of soil resources of the basin. Keywords: Heavy Metal, PCA, Urban Soils, Kabini Basin

“…Hence, the coastal margin along the west can play a key role in understanding the dynamics of continental and marine climatic trends. The west coast of India represents highly dynamic environment and ecosystem that is continuously undergoing pronounced changes through the Holocene to the present time (Babeesh et al, 2016; Chamyal & Merh, 1995; Lakhmapurkar & Bhatt, 2010; Pant & Juyal, 1993; Raj, 2007; Sridhar et al, 2014; Thakur et al, 2019).…”

“…Vembanad Coastal Wetland: The Vembanad coastal wetland (Ramsar site) is one of the largest tropical estuary and lies on the southwest coast of India between 9°00' and 10°40'N latitude and 76°00' and 77°30'E longitude that is presently located in the humid tropics, has a semidiurnal tidal cycle and receives generally consistent temperatures between 21°C and 36°C (Figure 2). The region receives average precipitation of 3,200 mm per year surrounded by marshes and is recognised for endemism-rich ecological habitats (Babeesh et al, 2016;Remani et al, 2010). Dhadhar Estuary: The Dhadhar River drains the region between the rivers Mahi and Narmada and has its source close to Shivrajpur at 22°30'N latitude and 73°45'E longitude in the Aravalli range (Figure 2).…”

Coastal margins and their ecological setting are one of the magnificent landforms on globe. The complex interaction among the different biotic and abiotic components through ages has addressed that due to climatic changes the coastal regions, one of the pioneer regions, have been getting affected and this may continue in the future also. The role of microfossils through ages has helped in delineating the past climatic manifestations and global changes and amongst them diatoms also provide a valuable tool for inferring past climate and ecological variability in the dynamic coastal system. In the study, a modern set of 77 samples from different climatic zones along the west coast of India has been studied to gain knowledge about the present-day climate status and record environmentally susceptible diatoms to form a modern analogue for coastal settings. The study shows various associations of planktic and benthic diatoms that hitherto provide precious information about the diatoms and their relation to the climatic regions and ecological status. The change in the frequency of planktic and benthic diatoms inculcate the water levels, pH, salinity changes, tidal variability and trophic status. Hence, the study aims to provide a robust database on diatoms for the various climatic zones from the west coast of India and would inevitably fill knowledge gap in terms of primary productivity for broad implications. The study also aims to provide background for transfer-based function for the reconstruction of long-term palaeoclimatic records for the transition zone of terrestrial and oceanic realms.

“…Similarly, chemical weathering indices in sediment cores from Kukkal Lake (Rajmanickam, Achyuthan, & Eastoe, 2016) offered insights into the southwest (SW) monsoonal fluctuations. Geochemical studies of sediments from Karlad (Babeesh, Achyuthan, & Sajeesh, 2018), Vellayani (Nair & Achyuthan, 2017), and Yercaud Lakes (Gopal, Achyuthan, Shah, & Jayaprakash, 2020) have focussed on aspects of palaeo-weathering and provenance.…”
