Dataset for "climatic gradient drives energy flow and consumer production in streams"
Bibliographic record
Abstract
As climate change disrupts precipitation patterns, its impact on ecosystems remains uncertain. Rainfall drives the ecology of rivers shaping flow regimes and riparian zones with potentially profound effects on productivity. Leveraging the steepest non-montane rainfall gradient in the continental United States, we conducted the first ever study of secondary production of both fish and invertebrates across multiple streams through multiple years. We found that fish productivity, biomass turnover rates, and annual variability in production doubled in drier regions, while invertebrate production and biomass also increased with decreasing rainfall. Additionally, food webs in arid regions shifted from detritus-based systems, driven by dense riparian vegetation, to algae-based systems, where open canopies and high light availability boosted algal growth and herbivore production. These findings reveal that changes in rainfall patterns due to climate change could dramatically reshape river ecosystems altering their productivity and food web structure and affecting ecosystem services and biodiversity.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
