Geochemical constraints on the origin of ophiolitic chert from Naga HillsOphiolite, Northeast India
(Indian Geophysical Union, 2025)The uppermost part of the Naga Hills ophiolite (NHO) sequence representing vestiges of the Neo-Tethyan ocean in the Indo-Myanmar ranges, consists of Late Jurassic to Late Cretaceous cherts that carapace the ophiolitic ... -
Experimental heating of CI chondrite: Empirical constraints on the evolution of micrometeorite O-isotopes during atmospheric entry
(Elsevier, 2025)Extraterrestrial dust exhibits a wide range of textural, chemical and oxygen isotopic compositions due to the heterogeneity of their precursors and modification during atmospheric entry. Experimental heating provides an ... -
Antimicrobial Potential of Marine Sponge-Associated Bacillus velezensis and Stutzerimonas stutzeri from the Indian Coast: A Genome Mining and Metabolite Profiling Approach
(Springer, 2025)Antimicrobial resistance (AMR) is one of the leading health crises worldwide that demands new antimicrobials to enter the clinical pipeline. Marine sponges are a rich source of promising bioactive compounds. Due to their ... -
Potent targeted larvicidal activities of marine-derived Bacillus sp. bacterial extracts on mosquito vectors
(Springer Nature, 2025)Mosquito vector-borne diseases are one of the leading causes of mortality and morbidity across the globe. Current vector control strategies mainly rely on chemical insecticides, but their incessant usage has resulted in ... -
Geochemistry and mineralogy of modern fjord sediments, west Spitsbergen, Svalbard: implications for provenance and weathering
(Springer, 2025)Arctic fjords are ideal sites for studying the recent sedimentary process that affects high-latitude coastal ecosystems. High latitude Raudfjord, Magdalenefjord, and St. Jonsfjord from the west Spitsbergen, Svalbard have ... -
Distribution, sources and bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in oysters of Sal estuary Goa, India
(Elsevier, 2025)Present study aimed to unfurl occurrence and accumulation of Polycyclic Aromatic Hydrocarbons (PAHs) in water and oysters of Sal estuary (Goa, India). The highest total PAHs concentration were observed at mid estuary (SSJ2) ... -
Vertical structure of mesoscale eddies and their impact on the modulation of tracer fields in the eastern Arabian Sea
(Springer, 2025)The present study utilises a combination of observation and ocean reanalysis data to comprehend the vertical structure of mesoscale eddies and their influence on the modulation of tracer properties (temperature, salinity, ... -
First report of a giant protist Tricranastrum trinibrachium Takahashi 1991 (syn. Myelastrum trinibrachium) from the Indian Ocean
(Oxford University Press, 2025)Rhizarians play an important role in ocean biogeochemistry and are used as paleoproxies. These organisms, specifically the giant ones, which are fragile in nature, are poorly studied and understood. A rhizarian species ... -
Phthalic acid esters as an ecological hazard to the coral reef ecosystems: A case study from the coral reef waters of the Lakshadweep Archipelago, Arabian Sea
(Elsevier, 2025)Information regarding the sources, distribution and ecological implications of organic contaminants in the coral reef ecosystems is limited. Phthalic acid esters (PAEs) are toxic contaminants due to their endocrine-disrupting ... -
Baseline oxidative stress responses and cytochrome P450 gene expression in Tympanotonos fuscatus from PAH-contaminated ecosystem in the Niger Delta, Nigeria
(Springer, 2025)The pervasive contamination of aquatic ecosystems by polycyclic aromatic hydrocarbons (PAHs) poses risks to benthic macroinvertebrates. This study investigates Tympanotonos fuscatus biochemical and molecular responses to ... -
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 ...
