Microbial keystone players and biogeochemical impacts of Noctiluca scintillans bloom in Mandovi estuary on west coast of India
(Elsevier, 2025)A sporadic outbreak of the bioluminescent dinoflagellate Noctiluca scintillans (NS) occurred in the Mandovi estuary along the Goa coast of the Central Eastern Arabian Sea on 24th May 2023, prompted by pre-monsoon upwelling, ... -
Anthropogenic stressors of black clam distribution in Kochi backwaters on the Indian west coast
(Springer, 2025)The black clam (Villorita cyprinoides Gray, 1825) is the most commercially important clam in India and the major share of its landing (around 25,000 tonnes/year) comes from Kochi backwaters (KBW), the largest estuarine ... -
Seasonal dynamics and environmental drivers of productivity in the Cochin Estuarine System: Insights from estuarine turbidity maxima
(Elsevier, 2025)The Cochin estuarine system, characterised by its Estuarine Turbidity Maximum (ETM) zones, undergoes significant seasonal variations influenced by riverine input and tidal forces. This study examined the seasonal shifts ... -
Dinoflagellate cyst and nannofossil imprints in the middle Eocene Kirthar transgressive strata from the western Garo Hills, South Shillong Plateau, India
(Elsevier, 2025)One of the global characteristic features of the Eocene is the extensive development of carbonate platforms in various regions of Tethys. Paleogene sequences of the Shillong Plateau from west to east are exposed in the ... -
Bacterial communities and their functional profiles from mangroves, a blue carbon ecosystem and terrestrial forest habitats
(Springer, 2025)Microorganisms play a crucial role in the biogeochemical cycling of organic matter through their heterotrophic activity. This study delves into comparing the sediment bacterial communities from the mangrove habitats of ... -
Thermal desiccation and relative gene expression of HSP90 in an acorn barnacle, Amphibalanus amphitrite
(Elsevier, 2025)Sessile and sedentary invertebrates respond to various magnitudes of thermally desiccated stress during tidal emersion, and regulation of body temperature plays a crucial role in survival during an intraday aerial exposure. ... -
Spatial and temporal dynamics of prokaryotes in the Eastern Arabian sea
(Springer, 2025)This study resolves the spatial and seasonal variations in prokaryotic abundance (PA) and biomass concerning physicochemical parameters during Spring Inter-Monsoon (April–May), Summer Monsoon (June–September), and Winter ... -
Environmental magnetism linked to weathering processes: A study on surface soils from an East Antarctic oasis,
(Elsevier, 2025)We determined and discussed the mineral magnetic properties of the soil samples (n = 78) from the Schirmacher Oasis, East Antarctica. Environmental magnetism analysis was conducted to identify the mechanisms controlling ... -
Central Indian Ocean Basin micrometeorite collections: Type, flux, etching and its implication to ocean biogeochemistry
(Elsevier, 2025)Extraterrestrial phenomena have influenced Earth’s processes throughout geological history. Evaluating the impact of extraterrestrial material on the environment is crucial for understanding the evolution of Earth and life. ... -
Do you believe in “new” fungal species?
(Association of Fungal Biologists, 2025)Fungal taxonomy has undergone a transformation in recent decades, propelled by the advent of molecular methodologies that have fundamentally reshaped traditional morphology-based species delineation. This paper examines ... -
Tidal control of heavy metal loading in the nearshore of the northwestern Indian coast
(Elsevier, 2025)Heavy metals accumulate in the marine food chain and their excessive amounts are hazardous to aquatic and human lives. The current study presents the role of ecosystem variables especially tides in deciding the presence ... -
Deciphering top-down impact of cerithiid gastropods on meiobenthic assemblages: insights from tropical estuaries along the central west coast of India
(Elsevier, 2025)Macro-epifaunal grazers influence the infaunal communities through top-down control in intertidal estuarine ecosystems. The present study aimed to investigate the influence of cerithiid gastropod Pirenella cingulata ... -
Carbon dynamics in the intertidal rockpools along the central west coast of India
(Elsevier, 2025)Shallow inter-tidal ecosystems such as rockpools provide important insights into the ongoing climatic changes and their consequences. We studied the diurnal and seasonal variations in carbon chemistry and associated ... -
Comparative Assessment of Heavy Metal Contamination and Pollution Trends in Indian Estuarine Sediments: Insights from East and West Coasts of India
(ACS Publications, 2025)This study presents a comparative assessment of heavy metal contamination in sediments from major Indian estuaries in recent decades. Metal concentration data were compiled from published literature and analyzed for Pb, ... -
Island mass effect alters the biogeochemistry of the coastal waters around Grande Island in the Eastern Arabian Sea
(Springer, 2025)Coastal oceans are highly dynamic regions of ecological and economic importance that are vulnerable to different stressors. We investigated the spatio-temporal variations in the biogeochemistry of the coastal waters ... -
Impacts of climate change on the morphodynamics of embayed beaches along the Central West Coast of India
(Elsevier, 2025)This study investigates the morphodynamics and climatic influences on twenty-seven embayed beaches along the central west coast of India utilizing a comprehensive framework that combines in-situ field observations and ... -
Metagenomic reconstruction of microbial genomes and biogeochemical pathways: insights into carbon and nitrogen flux dynamics in the eastern Arabian Sea
(Elsevier, 2025)The eastern Arabian Sea (EAS) experiences seasonal nutrient availability and productivity shifts driven by the Indian monsoon, influencing microbial contributions to biogeochemical cycles. This study explores carbon, ... -
Cost-effective copper nanoparticles for enhanced photocatalytic degradation of triarylmethane (TAM) dyes in direct seawater
(Elsevier, 2025)In recent years, the environmental impact of triarylmethane dyes (TAMs) has become an ever-increasing concern, as their widespread use in various industries has led to their persistent presence in wastewater, causing serious ... -
Community guidelines to increase the reusability of marine microfossil assemblage data
(The Micropalaeontological Society, 2025)Data on marine microfossil assemblage composition have multiple applications. Initially, they were primarily used for (chrono)stratigraphy and palaeoecology, but these data are now also widely used to study evolutionary ... -
Fatty acid and sterol biomarkers as indicators of symbiont activity in chemosynthetic organisms from a methane seep ecosystem (Krishna-Godavari basin, Bay of Bengal)
(Springer, 2025)In the present study, an attempt was made to characterize the bacterial symbionts present in the organisms, their carbon sources and assess tissue-specific isotope variability within the organisms in Bathymodiolus, ...
