Abstract

fetched live from OpenAlex

We monitored American dipper populations over two years at stream sites with and without Run-of-River (RoR) dams across three watersheds in coastal British Columbia, Canada. From September to November of 2014 and 2015, 99 adult dippers (n=48 in 2014 and n=51 in 2015, plus 3 recaptures from 2014) were banded at 13 (7 regulated, 6 unregulated) of the 14 study streams. Blood and feathers were collected during banding for mercury and stable isotope analysis. Streams were surveyed after initial banding attempts in the fall of 2014, during the spring of 2015 (before and after the freshet), and again during the fall of 2015. Density surveys followed the unreconciled independent double-observer approach to target American dippers, whereby each observer keeps a separate tally of all observations to facilitate an estimation of detection probability. We also applied the same method to other aquatic bird species and counted them during each survey. Survey data was used to compare density, seasonal occupancy, and assess differences in year-round residency and philopatry in dippers at regulated and unregulated streams.

Not 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.
