Abstract Increasing human activities and climate change have resulted in significant changes net primary production (NPP) of the marginal sea past several decades. The Bohai Sea (BHS) is a shallow semi‐enclosed North China, knowledge relative impacts on NPP BHS remains limited. This study primarily aimed to elucidate interannual variability its influencing factors during 2002–2021 period by synthesizing four widely‐used global models, namely vertically generalized model (VGPM), Eppley‐VGPM, size‐fractioned phytoplankton pigment absorption‐based (SABPM), carbon, absorption, fluorescence euphotic‐resolving (CAFE). multi‐model average showed variation, with an increasing trend from 2002 2012 decreasing 2021. concentration DIN was affected atmospheric nitrogen deposition. structural equation demonstrated that chlorophyll‐a (Chl‐a) concentration, influenced had important effect NPP. In brief, deposition impacted thus controlled Chl‐a BHS. Furthermore, potential ecological red tide features. These findings hold valuable implications for future marine resource planning management

Mariculture is currently experiencing rapid growth in response to the rising global food demand, while simultaneously posing significant challenges environmental issues, such as pollution stress and ecological degradation. To achieve a balance between ecosystem maintenance seafood supply, marine ranching has flourished sustainable approach through implementation of artificial reef construction, stock enhancement, strategic releasing. However, few studies have evaluated impacts comparison situ survey data across geographical areas. Phytoplankton are vital organisms ecosystems that function essential indicators seawater quality biological diversity, reflecting health sustainability. In this study, we investigated species community structure, co-occurrence network phytoplankton based on 175 samples collected from 75 sites encompassing all 26 areas, along with their corresponding surrounding areas Yantai’s coastal sea. A total 112 were identified three phyla diatoms, dinoflagellates, chrysophytes; among them, diatoms dominated notably high proportion 98.83%. Their diversity structure exhibited variations different seasons geographic locations. Moreover, no preference was observed Nevertheless, analysis demonstrated lower values for average degree, clustering coefficient, path length ranching, indicating aquaculture activities reduced connectivity potential interactions. Additionally, it showed stability indicated by remaining nodes natural indices, regardless removed. These findings illustrate processes can mitigate losses maintaining they still alter association reduce overall stability. This research recommends scientifically informed expansion necessitates robust monitoring datasets systematic validation ensure holistic

Dust deposition can supply nutrients to the upper ocean, and subsequently affect primary production biodiversity in planktonic ecosystem, but differential response among taxa their interactions are not fully understood. Here, we performed 7-day onboard incubation experiment amended with different dust loadings (0, 0.2 2 mg L -1 ) Kuroshio-Oyashio transition region of Northwest Pacific Ocean characterized community structure microbial network a microbiome addition. Chlorophyll nutrient analysis indicated that dust-derived nitrogen promoted growth phytoplankton (165.8–293.6%) size shifted towards larger cells (>3 μm). Metabarcoding sequencing, targeting prokaryotic eukaryotic microbes, revealed changes co-occurrence induced shift from dinoflagellate dominance toward diatom phytoplankton, favored members Cercozoa, Labyrinthulomycetes Saprospirae, which showed positive correlation diatom. Temporal patterns were categorized into five clusters, collectively pointed more sensitive microeukaryotic than one dust. The turnover during was dominated by moderate 55.71-62.26% OTUs transitioning abundant or rare taxa, addition stimulated transitions taxa. Moreover, biotic factors shaped abiotic factors, particularly cross-domain interaction significantly affected community. Notably, enhanced complexity, number keystone increased, suggesting interspecies With integrated analysis, our findings highlight sensitivity effects could pass on other organisms through interaction.
