Data from: Drivers of temporal beta diversity of a benthic community in a seasonally hypoxic ocean fjord
Bibliographic record
Abstract
Global expansion of oxygen deficient (hypoxia) waters will have detrimental effects on marine life in the Northeast Pacific Ocean (NEP) where some of the largest proportional losses in aerobic habitat are predicted to occur. However, few studies have accounted for the high environmental variability in this region while including natural community-assembly dynamics. Here, we present results from a 14-month deployment of a benthic camera platform tethered to the VENUS cabled observatory in the seasonally hypoxic Saanich Inlet. Our time series continuously-recorded, natural cycles of deoxygenation and reoxygenation that allowed us to test whether a community from the NEP showed hysteresis in its recovery compared to hypoxia-induced decline and to address the processes driving temporal beta diversity under variable states of hypoxia. Using high-frequency ecological time series we reveal (1) differences in the response and recovery of the epibenthic community are rate-limited by recovery of the sessile species assemblage, (2) both environmental and biological processes influence community assembly patterns at multiple time-scales, and (3) interspecific processes can drive temporal beta diversity in seasonal hypoxia. Ultimately, our results illustrate how different time scale dependent drivers can influence the response and recovery of a marine habitat under increasing stress from environmental change.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
