Chromosome-scale genome assembly of three-spotted seahorse (Hippocampus trimaculatus) with a unique karyotype.
Sci Data

Laboratory of Aquatic Genomics, College of Life Sciences and Oceanography, Shenzhen University, Shenzhen, 518057, China.
Three-spotted seahorse (Hippocampi trimaculata) is a unique fish with important economic and medicinal values, and its total chromosome number is potentially quite different from other seahorse species. Herein, we constructed a chromosome-level genome assembly for this special seahorse by integration of MGI short-read, PacBio HiFi long-read and Hi-C sequencing techniques. A 416.

Acanthopagrus latus (yellowfin seabream) is an economically important fish in the southeast coastal sea of China. Its slower growth rate makes it more prone to diseases in the cultivation period, leading to substantial economic losses. Epidemiological investigations have indicated that Streptococcus agalactiae is one of the most common Gram-positive pathogens, which has garnered increasing attention due to its high contagion and lethality rates in A.

Summer Arctic black carbon (BC) predominantly originates from boreal wildfires, significantly contributing to Arctic warming. This study examined the impact of MODIS-detected extensive East Siberian wildfires from 2019 to 2021 on Arctic BC and the associated radiative effects using GEOS-Chem and SNICAR simulations. During these years, Arctic surface BC aerosol concentrations rose to 46 ng m, 43 ng m, and 59 ng m, nearly doubling levels from the low-fire year of 2022.

East China Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Shanghai 200090, China. Electronic address:
Arsenic is a pervasive environmental pollutant that can bioaccumulate in Antarctic krill through the food chain, posing potential risks to human health. This study investigates the toxic effects of arsenic in Antarctic krill oil (AKO) on Caco-2 cells, focusing on oxidative stress and apoptosis induction. AKO is nutrient-rich and contains various arsenic species, including arsenite (As³⁺), arsenate (As⁵⁺), dimethyl arsinic acid (DMA), and arsenobetaine (AsB), each exhibiting different toxic potencies.

The increasing demand for sustainable alternatives to conventional plastics has propelled the interest in bioplastics. A few papers reported on the effects of plastics on crustaceans, but no indication about biodegradable polymers is available. Hippolyte inermis Leach, 1816 is a protandric shrimp commonly living on leaves of the seagrass Posidonia oceanica, in the Mediterranean Sea.
