Summary: This study analyzed the organic carbon stocks in Thalassia hemprichii meadows near and away from mangroves in the Andaman and Nicobar Islands of India. The content of organic carbon in the top 10 cm of sediment was 1.8 times higher at mangrove sites compared to non-mangrove sites. The total carbon stocks in the seagrass meadows at mangrove sites were 1.9 times higher than in non-mangrove sites.

Summary: This study investigated the evolutionary history of the Andaman cobra (N. sagittifera) and its venom characteristics, revealing the inadequate cross-neutralizing efficacy of Thai monovalent antivenom against N. sagittifera venoms. It emphasized the critical need to manufacture region-specific Indian antivenoms.

Summary: This study presents modern pollen, non-pollen palynomorphs, and grain size data from a pristine mangrove tidal creek on South Andaman Island, India. The results highlight the relationship between local vegetation pollen and regional vegetation surrounding the depositional site, showing the importance of understanding pollen assemblages and the environmental conditions in reconstructing paleovegetation and paleoclimate.

Summary: This study integrates satellite optical images and DEM-based hydrogeomorphic features to enhance real-time identification of river flooding. The proposed integrated approach demonstrates good performance in detecting flooded areas, reducing false alarms, and allowing for rapid assessment of large areas in the aftermath of flooding events.

Summary: This study was the first-ever conducted on the prevalence of Trichomonas vaginalis (TV) in the Andaman and Nicobar Islands. The study found a 0.9% infection rate, with the majority of infected individuals having lower education levels and being unemployed. The detection of the TV G3 strain may be important for understanding the prevalence of TV infection and associated risk factors. More research is needed to understand the TV-associated risk factors among suspected patients in hospital settings.

Summary: Accurate and timely estimation of cotton yield over large areas is essential for precision agriculture, and remote sensing and crop models are effective means to predict cotton yield. This study identified the most important factors for estimating county-level cotton yield across Xinjiang Province and utilized different approaches for yield estimation, with the long short-term memory (LSTM) performing the best.

Summary: India, the world's largest cattle producer and self-proclaimed self-sufficiency in dairy production, faces a challenge as 68% of its milk is reported to be adulterated. This study presents a novel model for studying milk safety in the Andaman and Nicobar Islands and highlights the limitations of the current approach to dairy assessment. The study reveals a deficit in fluid milk production in the region and a lack of awareness among farmers regarding milk safety.

Summary: This study analyzed the natural regeneration potential of Andaman Padauk under different disturbance regimes. The species showed luxuriant growth at the leading edge of its habitat, while trees were more abundant at the trailing edge. There was a strong proportionality between the height and diameter of regenerates. These findings have important implications for assessing the natural regeneration potential of other species facing population decline.

Summary: The study explores the ichnofabrics of chalks from the Inglis Formation in the Andaman and Nicobar Islands, revealing multiple colonization, complex tiering, and multilayer tiering. Analysis suggests deposition in a lower bathyal paleoenvironment and highlights the role of organic matter, pore water, and bottom-water oxygenation as controlling factors in the formation of chalk sediments during the Early-Middle Miocene.

Summary: The study examined the abundance of various bacteria in the marine ecosystem around the Andaman and Nicobar Islands during the monsoon season, focusing on the higher counts of heterotrophic, indicator, and pathogenic bacteria near the 10 degrees channel, which is the principal route to reach the Andaman mainland. Most sampling stations were located offshore to cover shipping tracks, with the closest station 21 km away from the coast, and detected various pathogenic bacteria such as Aeromonas hydrophila, Enterobacter aerogens, and Vibrio parahaemolyticus.

Summary: Studies on zoantharians from Indian waters are scarce. Most studies focus on intertidal species, while exploration of shallow coastal waters is lacking. This study reports the first record of Sphenopus marsupialis from the Andaman and Nicobar Islands. Detailed morphological features and distributional ranges are provided.

Summary: Satellite derived bathymetry (SDB) is a significant and cost-effective method for obtaining shallow seabed topography. This study proposes an SDB approach incorporating spectral and spatial information of multispectral images to improve the accuracy of bathymetry inversion. Experimental results show that the method effectively reduces the error in bathymetry estimation caused by spatial heterogeneity of the seabed.

Summary: The study found that microseisms in the Andaman-Nicobar region are significantly influenced by local climatology and geomorphology, with long-period microseisms being associated with distant sources in the South Indian Ocean. Primary microseisms in this area are weak and not correlated with any ocean wave parameters.

Summary: This study examined the prevalence of skin diseases in the Andaman and Nicobar islands over a two-year period, identifying common disorders such as cutaneous infections and Hansen's disease. The findings can serve as valuable insight for healthcare planning on the islands and even on the mainland due to the population diversity.

Summary: Dragon fruit, a tropical fruit rich in essential nutrients, was characterized in this study using morphological, biochemical, and molecular techniques to distinguish three species well adapted to Andaman and Nicobar Island. Significant genetic variations were observed, particularly in fruit traits. Peels exhibited higher antioxidant potential compared to pulp, with key traits for distinguishing species being pulp/peel colour, number of spines, and length of areoles in cladode. Genotypes with high carotenoid and xanthophylls content may have industrial importance in addressing vitamin-A deficiency in tropical regions.
