The Contrasting Role of Marine- and Land-Terminating Glaciers on Biogeochemical Cycles in Kongsfjorden, Svalbard.

This case study of Kongsfjorden, western coastal Svalbard, provides insights on how freshwater runoff from marine- and land-terminating glaciers influences the biogeochemical cycles and distribution patterns of carbon, nutrients, and trace elements in an Arctic fjord system. We collected samples from the water column at stations along the fjord axis and proglacial river catchments, and analyzed concentrations of dissolved trace elements, together with dissolved nutrients, as well as alkalinity and dissolved inorganic carbon. Statistical tools were applied to identify and quantify biogeochemical processes within the fjord that govern the constituent distributions.

Peripheral B Lymphocyte Serves as a Reservoir for the Persistently Covert Infection of Mandarin Fish Ranavirus.

Mandarin fish ranavirus (MRV) is a distinctive member among the genus of the family . The persistently covert infection of MRV was previously observed in a natural outbreak of MRV, but the underlying mechanism remains unclear. Here, we show that mandarin fish peripheral B lymphocytes are implemented as viral reservoirs to maintain the persistent infection.

In this comprehensive study, we utilized a multiomics approach to characterize neuropeptide precursors and to assess the expression profiles of neuropeptide-encoding genes across various tissues and developmental stages in the Pacific white shrimp, . Additionally, we explored the differential expression of neuropeptide genes in the eyestalk before and after the RNA interference-mediated suppression of crustacean hyperglycemic hormone (CHH) and vitellogenesis-inhibiting hormone (VIH) gene expression.

How does globally accumulated tropical cyclone energy vary in response to a changing climate?

How tropical cyclone (TC) activity varies in response to a changing climate is widely debated. The accumulated cyclone energy (ACE) is one of the indicators of TC activity and has attracted considerable attention because of its close relationship with the damages caused by TCs. Previous studies have focused on detecting long-term trends in global ACE; however, the results are inconclusive.

Coral-Symbiodiniaceae symbiotic associations under antibiotic stress: Accumulation patterns and potential physiological effects in a natural reef.

Antibiotics threaten scleractinian corals, but their accumulation patterns and physiological effects on corals in natural reefs remain unclear. This study investigated antibiotic occurrence in seawater and two coral species, Galaxea fascicularis and Pocillopora damicornis, and explored the physiological effects of bioaccumulated antibiotics in a fringing reef of the South China Sea. Nineteen antibiotic components were detected in seawater, with total antibiotic concentrations (ΣABs) ranging from 17.

plecoglossicida infection induces neutrophil autophagy-driven NETosis in large yellow croaker .

Neutrophil extracellular traps (NETs) are crucial for the immune defense of many organisms, serving as a potent mechanism for neutrophils to capture and eliminate extracellular pathogens. While NETosis and its antimicrobial mechanisms have been well studied in mammals, research on NETs formation in teleost fish remains limited. In this study, we used the large yellow croaker () as the study model to investigate NETosis and its role in pathogen defense.

Comparative genomics analyses of Actinobacteriota identify Golgi phosphoprotein 3 (GPP34) as a widespread ancient protein family associated with sponge symbiosis.

Background: Sponges harbor microbial communities that play crucial roles in host health and ecology. However, the genetic adaptations that enable these symbiotic microorganisms to thrive within the sponge environment are still being elucidated. To understand these genetic adaptations, we conducted a comparative genomics analysis on 350 genomes of Actinobacteriota, a phylum commonly associated with sponges.

Palmitoylation-mediated NLRP3 inflammasome activation in teleosts highlights evolutionary divergence in immune regulation.

NLRP3 inflammasome activation is pivotal for cytokine secretion and pyroptosis in response to diverse stimuli, playing a crucial role in innate immunity. While extensively studied in mammals, the regulatory mechanisms governing NLRP3 activation in non-mammalian vertebrates remain largely unexplored. Teleosts, as basal vertebrates, represent an ideal model for exploring the evolutionary trajectory of inflammasome regulation.

The DnaJ-Hsp70-Hsp90 co-chaperon networks in scallops under toxic Alexandrium dinoflagellates exposure.

Heat shock proteins (Hsps) are highly conserved molecular chaperones with essential roles against biotic and abiotic stressors. A large set of co-chaperons comprising J-domain proteins (DnaJs) regulate the ATPase cycle of Hsp70s with Hsp90s, together constituting a dynamic and functionally versatile network for protein folding/unfolding and regulation. Marine bivalves could accumulate and tolerate paralytic shellfish toxins (PSTs), the well-noted neurotoxins generated during harmful algal blooms.

Polystyrene microplastics exhibit toxic effects on the widespread coral symbiotic Cladocopium goreaui.

Within the coral reef habitat, members of the Symbiodiniaceae family stand as pivotal symbionts for reef-building corals. However, the physiological response of Symbiodiniaceae on microplastics are still poorly understood. Research conducted in this investigation assessed the harmful impact of polystyrene microparticles (PS-MPs) on Cladocopium goreaui, a Symbiodiniaceae species with a broad distribution.

The physiological stress response of juvenile nurse sharks (Ginglymostoma cirratum) to catch-and-release recreational angling.

Nurse sharks (Ginglymostoma cirratum), especially juveniles, are often encountered by near-shore and shore-based recreational anglers and are suggested to exhibit minimal behavioral and physiological responses to capture, largely based on studies of adults using commercial or scientific fishing methods. To quantify the sub-lethal effects of recreational angling on juvenile nurse sharks, 27 individuals (across 31 angling events) were caught using hook-and-line fishing methods. Over a 30-min period, 4 blood samples were taken with variable time intervals between sampling (i.

Cross-kingdom regulation of plant microRNAs: potential application in crop improvement and human disease therapeutics.

Plant microRNAs (miRNAs) are small non-coding RNA molecules that usually negatively regulate gene expression at the post-transcriptional level. Recent data reveal that plant miRNAs are not limited to individual plants but can transfer across different species, allowing for communication with the plant, animal, and microbial worlds in a cross-kingdom approach. This review discusses the differences in miRNA biosynthesis between plants and animals and summarizes the current research on the cross-species regulatory effects of plant miRNAs on nearby plants, pathogenic fungi, and insects, which can be applied to crop disease and pest resistance.

A mechanosensitive circuit of FAK, ROCK, and ERK controls biomineral growth and morphology in the sea urchin embryo.

Biomineralization is the utilization of different minerals by a vast array of organisms to form hard tissues and shape them in various forms. Within this diversity, a common feature of all mineralized tissues is their high stiffness, implying that mechanosensing could be commonly used in biomineralization. Yet, the role of mechanosensing in biomineralization is far from clear.

Microenvironmental modulation breaks intrinsic pH limitations of nanozymes to boost their activities.

Functional nanomaterials with enzyme-mimicking activities, termed as nanozymes, have found wide applications in various fields. However, the deviation between the working and optimal pHs of nanozymes has been limiting their practical applications. Here we develop a strategy to modulate the microenvironmental pHs of metal-organic framework (MOF) nanozymes by confining polyacids or polybases (serving as Brønsted acids or bases).

Ecology of endolithic bryozoans: colony development, growth rates and interactions of species in the genus Immergentia.

Boring bryozoans dissolve calcium carbonate substrates, leaving unique borehole traces. Depending on the shell type, borehole apertures and colony morphology can be diagnostic for distinguishing taxa, but to discriminate among species their combination with zooidal morphology is essential. All boring (endolithic) bryozoans are ctenostomes that, along with other boring taxa, are common in benthic communities.
