Do fish in an urban river system use a rehabilitated and reconnected stormwater pond during the summer?
Bibliographic record
Abstract
For mobile animals such as fish, different habitat types at various life stages are required to support a broad range of ecological requirements. However, in urban areas, access to suitable habitat may be impeded. Moreover, rehabilitation efforts focused on urban waterbodies are infrequent, small-scale, and inadequately monitored. We characterized the connectivity of the fish community between the Jock River in eastern Ontario and a rehabilitated stormwater management pond during late spring. Passive integrated transponder (PIT) tags were implanted into over 800 individual fish, representing sixteen species with a wide range of body sizes and life-histories. Summer residency and behavior were assessed using detections from an array of autonomous PIT receiver stations. This research revealed that there is ecological connectivity between an adjacent rehabilitated stormwater pond and the Jock River. Some species were resident in the pond during the entire summer monitoring period while others such as sunfish ( Lepomis sp.) and rock bass ( Ambloplites rupestris ) made regular forays between the river and the pond. There was also evidence of significant movement within the pond for species such as golden shiner ( Notemigonus crysoleucas ) and northern pike ( Esox lucius ). This study demonstrates the potential for created habitats in floodplain areas initially intended for stormwater management to be rehabilitated to provide significant ecological value in urbanized watersheds.

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.
