ABSTRACT Soil organic carbon (SOC) in cropland is a critical component of the global cycle, representing most dynamic segment pool, and vital to addressing both “dual‐carbon” goals food security challenges. However, current research on SOC China's croplands has limitations timeliness, continuity, accuracy. This study constructed machine learning model assess spatial–temporal distribution changes across China. It maps annual China over past four decades (1980–2020), leveraging data from 2399 sampling points collected second soil census integration multi‐platforms combined with 22 environmental excoriates. The model's accuracy ( r = 0.82) could meet needs analysis perform reliably predicting China, high uncertainty only some areas, such as northeast. reveals that while there have been fluctuations stocks years, overall trend upward, increasing at rate 0.012 Pg C y −1 , generally functions sinks. Furthermore, Shapley additive explanations indicate temperature strongly correlates croplands, followed by precipitation topography. outcomes this provide essential support for formulating policies protection, land degradation, peak strategies

Abstract It is critical that fish's habitat uses of benthic habitats are understood, to inform effective fisheries management and predict the impacts human activities climate change. In this study, landers were used collect long-term high-temporal resolution data gain insights into use sponge grounds by fish at Sambro Bank Conservation Area. An integrated ecosystem-based monitoring approach was used, involving collected on biology, food supply, oceanography. Fish abundance, behaviour complex benthopelagic interactions analysed over spatial extended temporal scales (i.e., 30-minute intervals from 2021–2023). A total 21 different planktivorous benthivorous taxa found utilise seafloor. We show can act as a nursery, feeding shelter for commercially important fish. In-depth analyses Redfish, urophycid hakes, Silver Hake revealed distinct diel seasonal patterns showed how food, density current speed drivers their abundance behaviour. Supported fishery trawl survey reports, ecosystem importance environmental Such information crucial developing implementing robust, evidence-based policy management.
