Thermal refuge modeling: a short review
Bibliographic record
Abstract
Thermal refuges in river systems play a vital role in safeguarding aquatic organisms, particularly cold-water poikilotherms, during extreme temperature events. These refuges are characterized by localized temperature anomalies under the influence of different natural meteorological, hydrological, and geomorphological factors or human activities. The identification, prediction, and protection of thermal refuges have gained importance due to the rising impact of climate change and anthropogenic activities on river temperatures. Models have become increasingly used for addressing related concerns and applied questions in river science. This review examines various modeling approaches of thermal refuges, focusing on deterministic and statistical/stochastic models applicable in river environments. Deterministic models provide a process-based understanding of thermal dynamics, while statistical/stochastic models offer insights into spatial and temporal patterns by correlating thermal refuges/plumes to different controlling parameters. By analyzing the strengths and limitations of these methodologies, this review highlights their complementary roles in advancing thermal refuge research and management. Emerging opportunities, such as integrating thermal infrared imagery and machine-learning algorithms, underscore the potential for enhancing predictive capabilities in this critical field.

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.
