Acoustic recognition of tilapia feeding intensity via LoRA-fine-tuned multimodal large language models

Real-time assessment of fish feeding intensity is essential for demand-based feeding in intensive aquaculture, yet existing methods rely on external spectrogram preprocessing and large annotated datasets, limiting practical deployment. This study proposes an end-to-end approach t...

Climate change and extreme hydroclimatic events primarily regulate sedimentary organic carbon sequestration in an alpine lake on the Tibetan Plateau

Long-term carbon sequestration dynamics of alpine lakes on the Tibetan Plateau under dual pressures from ongoing climate warming and frequent climatic extremes remain poorly understood. Here, we reconstructed century-scale organic carbon burial dynamics and identified organic car...
