De Novo Transcriptomic Response of Pirenella cingulata (Gastropoda) Infected with Acanthotrema tridactyla (Trematoda)
(Springer, 2025)Pirenella cingulata- a snail from an intertidal mudflat serves as the first intermediate host of digenean trematode parasites. These trematode parasites castrate their host and alter the host's physiology for their own ... -
Measurement of soluble aerosol trace elements: inter-laboratory comparison of eight leaching protocols
(European Geosciences Union, 2025)A range of leaching protocols have been used to measure the soluble fraction of aerosol trace elements worldwide, and therefore these measurements may not be directly comparable. This work presents the first large-scale ... -
Subsurface phytoplankton community dynamics in the North Eastern Arabian Sea and their response to elevated light intensities under ocean warming scenario
(Springer, 2025)Phytoplankton are essential components of the earth’s ecosystem, forming the basis of the marine food chain. Variations in environmental conditions across the vertical scale in the ocean profoundly impact phytoplankton ... -
Source and Distribution of Organic Matter in the Andaman Backarc Basin Sediments: Insights from Rock-Eval Pyrolysis and Palynofacies Analysis
(Geological Society of India, 2025)The present research characterises the organic matter composition in sediments from the Andaman Backarc Basin using a combined approach of Rock-Eval pyrolysis and palynofacies analysis. The integration of these techniques ... -
Recent oxygenation of oxygen minimum zone in the Arabian Sea and possible causes
(Elsevier, 2025)Dissolved oxygen (DO) in the ocean is crucial for the survival of marine organisms and a prolonged exposure to sub-optimal levels impacts their life and species distribution. The oxygen minimum zones (OMZs) are the regions ... -
Microplastic contamination in water and organs of Deveximentum insidiator (Ponyfish) from a potential fishing zone off Mangalore, southeastern Arabian Sea
(Elsevier, 2025)This study investigates microplastic (MP) contamination in Deveximentum insidiator (pony fish or silverbellies), a commercially important species in the Indo-West Pacific, with samples collected from a Potential Fishing ... -
Polycyclic aromatic hydrocarbons in surface sediments of a highly dynamic estuarine-coastal ocean continuum on the southwest coast of India: Seasonal distribution, source apportionment, and toxicological implications
(Elsevier, 2025)The contamination status and ecological implications of polycyclic aromatic hydrocarbons (PAHs) from the river and estuarine systems are widely reported. However, information on their seasonal dynamics, contamination status ... -
Photoinhibition and β-carotene production from Dunaliella sp. isolated from salt pans of Goa
(Springer, 2025)The microalgae Dunaliella is a commercially viable species and is well known for its extreme environmental tolerance and ?-carotene production under stressful conditions. We examined the effect of salinity and light intensity ... -
Sibling species differently distributed around a CO2 vent show transplantation proteomic remodelling, while displaying metabolomic signatures associated with their origin
(Springer Nature, 2025)The cellular homeostatic response (CHR) and cellular stress response (CSR) work together to maintain homeostasis. Studying phylogenetically closely-related species inhabiting different environments can help investigate the ... -
Distribution and climatological trajectories of plastic debris released from the major rivers along the east coast of India using the Lagrangian particle tracking model
(Springer Nature, 2025)Marine plastic pollution predominantly originates from rivers, yet the extent of its return to shorelines remains uncertain. This study employs a Lagrangian particle tracking model to simulate the trajectories of plastic ... -
Taxa specific grazing-induced phytoplankton chlorophyll breakdown pathway: implication in algal bloom monitoring and mitigation programs
(Taylor and Francis Online, 2025)The roles of biotic factors (grazing/senescence) in chlorophyll a (Chl a) breakdown (CB) to non-fluorescence derivatives in a multistep pathway are frequently reported. In aquatic microalgae, the information on CB-pathway ... -
Functional Redundancy as an Indicator of Potential Ecosystem Stability: a Case Study on Macrobenthic Polychaete Communities from a Highly Urbanized Coast
(Springer Nature, 2025)In urban coastal habitats, prolonged intensified human activities significantly alter global ecological communities by losing species and their associated functions, resulting in a regional species pool where different ... -
Unraveling the bacterial composition of a coral and bioeroding sponge competing in a marginal coral environment
(Frontiers, 2025)The newly described bioeroding sponge Cliona thomasi, part of the Cliona viridis complex, is contributing to coral decline in the central eastern Arabian Sea, the West Coast of India. While its morphological and allelopathic ... -
Atmospheric Deposition, Shelf Sediment Supply, Riverine Input, and Redox Conditions Control Dissolved Manganese in the Indian Ocean
(Wiley Online Library, 2025)Abstract Dissolved manganese (dMn) is an essential bioactive element required for marine organisms. Redox condition determines its solubility and its solid phase removal from seawater. It displays a typical scavenging type ... -
Seismic chimneys as gas migration pathways and their role in hydrate accumulation: AVA insights from the Cauvery-mannar basin
(Elsevier, 2025)Gas hydrates have been identified in the Cauvery-Mannar Basin, a passive rift setting largely devoid of recent tectonic activity as evidenced by seismic data. This study provides novel insights into gas migration pathways ... -
Pre-requisite conditions for the intensification of pre-monsoon cyclones over the Bay of Bengal
(Springer Nature, 2025)The intensification of pre-monsoon cyclones in the northern Bay of Bengal, particularly Cyclone Yaas (2021), is increasingly attributed to the rising influx of freshwater from the Ganges and Brahmaputra rivers. Cyclone ... -
Global marine plastic pollution: Sources, distribution, implications on human health and mitigation strategies
(Elsevier, 2025)Plastic pollution has emerged as a pressing environmental crisis, with global production surging from 2 million tonnes per year in the 1950s to a staggering 460 million tonnes in 2019. A substantial portion of this plastic ... -
Responses of zooplankton (copepods) in the Indian mud bank-upwelling region
(Elsevier, 2025)In 2014 and 2016, the ecology and composition of zooplankton in the Alappuzha mud bank-upwelling area along the southwest (Kerala) coast of India were studied using biweekly sampling from the Pre-Monsoon (PRM) in April to ... -
Shift in the phytoplankton composition associated with reversal in east India coastal currents in the Bay of Bengal
(Elsevier, 2025)The alteration of phytoplankton composition due to variations in physical mixing, salinity, nutrient concentrations and their stoichiometric ratios would impact the overall ecosystem, affect the food web and influence the ... -
Marine biofilm microbial communities on deep-sea moorings as indicators of a changing environment
(Elsevier, 2025)Marine biofilms developed on buoys encasing Acoustic Doppler Current Profilers (ADCPs), deployed on deep-sea moorings for current measurements, were characterized for the first time along the continental slope of the west ...
