Plankton play an indispensable role in the biogeochemical processes of marine ecosystem. However, unraveling intricate interactions among biodiversity, trophic linkages, and biotic-abiotic interplay between phytoplankton-zooplankton remains a significant challenge. Here, we conducted field studies neritic area Bohai Sea during autumn 2023 spring 2024 to explore seasonal variations both phytoplankton zooplankton through microscope. Our analysis revealed sharp decline across zooplankton, with abundance ratio being 5.5 times higher than 2024. Additionally, dominant plankton species (Y ≥ 0.02) exhibited obvious differences two seasons, diversity observed autumn. Moreover, each had distinct preferred food items Rhizosolenia setigera favored by Noctiluca scintillans Acartia pacifica. Furthermore, multivariate biota-environment indicated that unique correlation specific environmental parameters, highlighting how can fully exploit external conditions survive variations. Ultimately, our findings emphasize dynamics provide solid foundation for assessing potential impacts changes on coastal realm.

Abstract The Svalbard archipelago region is one of the fastest warming regions in world. majority has occurred wintertime, although summer season also been approximately linearly since 1980. Nevertheless, recent years, many monthly and seasonal temperature records have set summer, with 2024 breaking its mean August by largest margins measurement history. In this study, we examine 2024s extremes. stands out as falling outside climatological distribution even after accounting for trend. Our findings suggest that are a result an unprecedented combination persistent atmospheric patterns interaction seas. Given exceptional nature these extremes, recommend further research to potential increase persistence weather consequences associated

Atlantification-the northward inflow of anomalous waters and biota from the Atlantic into polar basins-has wide-ranging climatological ramifications. We present previously unknown observational evidence that atlantification processes are strengthening in eastern Eurasian Basin. The primary example is diminishing sea ice, which related to a powerful ocean-heat/ice-albedo feedback, accelerates sea-ice losses. Furthermore, we observe extending far beyond Lomonosov Ridge Makarov Basin Arctic Ocean where upper ocean ventilation creates new unique ecological environment. part Siberian still strongly stratified, but atlantification-driven shoaling warm, salty, nutrient-rich intermediate already has important consequences there. Disentangling role multiple complex high-latitude changes should be priority future modeling efforts.

Climate change is rapidly modifying biodiversity across the Arctic, driving a shift from Arctic to more boreal ecosystem characteristics. This phenomenon, known as borealization, mainly described for certain functional groups along sub-Arctic inflow shelves (Barents and Chukchi Seas). In this review, we evaluate spatial extent of such alterations well their effects on ecosystem-level processes risks. Along shelves, borealization driven by long-term strengthened increasingly warm waters south punctuated advection low sea ice extreme events. A growing body literature also points an emerging other shelf ecosystems, through “spillover” effect, local changes in environmental conditions enable movement or transport new species shelves. These modifications are leading groups, although many uncertainties remain regarding under-sampled microbes, technical challenges consistent, regular monitoring regions. There clear consensus that affecting phenology, composition, community traits, population structure essential habitats, interactions, resilience. Non-dynamic factors, depth photoperiod, thought limit complete system, may lead intermediate, “hybrid” ecosystems future. We expect current borders progress further northward ultimately reach equilibrium state with seasonal borealization. Risks system difficult estimate, adaptive capacities poorly understood.
