Multi-tracer evaluation of cesium-137 bioaccumulation and trophic transfer in marine organisms off Jeju Island, Korea

Radionuclides accidentally released from nuclear facilities into the marine environment may affect ecosystems far from their original sources, yet their ecological behavior in such regions remains poorly understood. Using a multi-tracer approach, we evaluated 137 Cs bioaccumulati...

Interactive dynamics of particulate and dissolved organic matter under sustained hypoxia conditions in a semi-enclosed bay (Jinhae Bay)

We investigated the isotopic variation of particulate and dissolved organic matter (OM; δ 13 C POC , δ 15 N PN , δ 13 C DOC ) associated with the frequent occurrence of hypoxia in a semi-enclosed bay (Jinhae Bay, South Korea). During the hypoxic period (August–October 2024), surf...

Growth and reproduction of Japanese seabass, Lateolabrax japonicus , in the southern waters off the Korean Peninsula

Abstract Japanese seabass ( Lateolabrax japonicus ) is a commercially and ecologically important species found in Korean waters, which functions as a top predator in coastal marine ecosystems. However, research on the reproduction and growth of L. japonicus in Korean waters remai...

Inactivation of Escherichia coli and Bacillus cereus in Myungran jeotgal (Korean traditional salted pollack roe) using floating electrode-dielectric barrier discharge plasma

Nonthermal plasma technology has garnered significant attention for its food preservation capabilities. However, the applicability of floating electrode–dielectric barrier discharge (FE-DBD) plasma in this regard has not been explored. Therefore, the effects of FE-DBD plasma (1.1...

Mitogenomic characterization and phylogenetic placement of the mottled wood-owl strix ocellata with gene rearrangement patterns in strigiformes

Abstract Owls (order Strigiformes) represent a highly specialized lineage of nocturnal raptors, within which the genus Strix (family Strigidae) comprises several widely distributed species despite the limited availability of comprehensive mitogenomic data. In this study, the comp...

Comparative Evaluation of SELECT and Generalized Additive Models for Estimating Gillnet Selectivity of Snow Crab (Chionoecetes opilio) in the East Sea of Korea

This study evaluated snow crab (Chionoecetes opilio) gillnet selectivity using the traditional Share Each Length’s Catch Total (SELECT) framework and a generalized additive model (GAM). Comparative fishing experiments were conducted in the East Sea of Korea using four stretched m...

Micromorphology of the Aristotle’s Lantern in the Sand Dollar, Scaphechinus mirabilis (Echinoidea: Echinolampadacea): Insights from Scanning Electron Microscopy and Three-Dimensional X-Ray Microscopy

The morphology and micromorphology of Aristotle’s lantern, the feeding apparatus of Scaphechinus mirabilis, were examined using light microscopy, scanning electron microscopy, and X-ray microscopy. S. mirabilis had food grooves on the ventral side, which extended to the mouth. Ar...

A retrospective study on the diseases of roe deer in Jeju (2008-2011)

This study was carried out using 58 roe deer carcasses in Jeju from April 2008 to October 2011. According to necropsy and laboratory examinations such as pathologic, parasitic, and bacterial tests, 17 (29.3%) bacterial infections, 49 (84.5%) parasitic infections, and 14 (24.1%) n...

Cellular Toxicity of Short‐ and Long‐Term Exposures to Polystyrene Nanoplastics and Microplastics in Fish Skin Cell Derived From Fathead Minnow ( Pimephales promelas )

ABSTRACT The ubiquitous presence of microplastics and nanoplastics (MNPs) is raising concerns about their impact on the health of humans and other living organisms. Due to its tiny size, this particle can accumulate and circulate in the body after uptake, resulting in a variety o...

Age Structure and Growth of the Japanese Spanish Mackerel (Scomberomorus niphonius) in Korean Waters

In this study, we estimated the age and growth of S. niphonius using otolith-based age determination. Five hundred and thirty individuals were sampled from commercial fisheries and the National Institute of Fisheries Science research vessels in Korean waters between January and D...
