High-frequency broadband acoustics can provide fine spatial resolution for near-range fish measurements, but the performance and limitations of beam-position-resolved backscatter measurements require careful evaluation. This proof-of-concept study examined one commercially sourced, dead, previously frozen specimen of each of three cultured fishes: golden pompano (Trachinotus ovatus; 24.4 cm), mandarin fish (Siniperca chuatsi;...

Climate change is reshaping the distributions of marine species and disrupting functional connectivity among protected areas, yet few studies have quantified how these shifts alter the performance of marine protected area (MPA) networks. This study assessed climate-driven changes in functional connectivity for eight economically important fish species across 193 coastal MPAs in China under current conditions and two end-of-cen...

Understanding how climate change and anthropogenic stressors jointly affect threatened marine species is critical for conservation planning, yet integrated assessments remain scarce in China’s coastal waters. Using an ensemble species distribution modelling framework (Biomod2) with six algorithms, we projected habitat suitability for ten threatened marine species under climate-only and global-change scenarios for 2040–2050 und...

Accelerating climate change and chronic anthropogenic pressures demand connectivity-based design of marine protected area networks (MPANs). Yet integrating dynamic species responses and cumulative human pressures into spatial planning remains a key challenge, particularly in marginal seas at the land–ocean interface. As a biodiversity hotspot under intensive development, the Yellow and Bohai Seas (YBS) exemplify this complexit...

CO2-assisted steam huff and puff is an effective method to improve oil recovery and store CO2 in heavy oil reservoirs. However, few studies focused on complex geological formations, such as bottom water. The bottom water condition not only complicates the process of oil production and CO2 sequestration, but also makes migration and distribution of oil, water and CO2 unclear. In this paper, a numerical geological model of an of...

Multistep-ahead forecasting of chlorophyll concentration is of great significance in red tide early warning systems. Existing methods often neglect the potential adverse interactions between non-predictive variables and chlorophyll while failing to fully utilize the effective information in historical decoder units. To address these issues, this paper proposes a Dynamic Collaborative Attention Network (DCAN) model for chloroph...
