Generation-scale movement patterns of cutthroat trout (<i>Oncorhynchus clarkii pleuriticus</i>) in a stream network
Bibliographic record
Abstract
Movements by stream fishes have long been the subject of study and controversy. Although much discussion has focused on what proportion of fish adopt mobility within particular life stages, a larger issue involves the lifetime movements of individuals. I evaluated movements of different sizes and ages of Colorado River cutthroat trout ( Oncorhynchus clarkii pleuriticus ) using a variety of sampling methods from 1996 to 2001 in a 40 km network of main-stem and tributary segments of the North Fork Little Snake River, Wyoming, USA. The probability of movement was related to the period of observation, initial location, and possibly individual growth rate, whereas distance moved was related to fish size and initial location. Furthermore, it appeared that movements by juveniles were mostly downstream, whereas those of older fish were largely upstream. Movement of cutthroat trout in this basin appeared to be driven by ontogenetic changes in habitat use and variation in habitat productivity. Given that this stream network exemplifies the complexity typical of many mountain watersheds, movement as a life history tactic in fishes may be more common than is sometimes recognized.

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.
