Oxygen-deficit history predicts biological recovery debt after dissolved-oxygen compliance in managed freshwaters

The study combines high-frequency dissolved-oxygen monitoring, a controlled prior oxygen-history recovery experiment in juvenile bighead carp and grass carp, and independent managed-waterbody low-oxygen–reoxygenation event validation. The repository contains processed data, source tables, model outputs, codebook files and R scripts used to reproduce the oxygen-history descriptors, recovery-debt indices and external validation model comparison reported in the manuscript.

The deposited files include field dissolved-oxygen logger summaries, oxygen-deficit duration and cumulative deficit-load metrics, achieved exposure and water-quality tables, respirometry-derived recovery-debt data, systemic physiological records, metabolic and branchial recovery-debt summaries, targeted protein-level stress-response summaries, integrated recovery-debt index outputs, independent external validation stage-level input data and Table 3 model-comparison outputs.
