Understanding patterns of residency and space use of Arctic Skates (Amblyraja hyperborea) in Scott Inlet, Canada to inform indigenous fisheries
Bibliographic record
Abstract
Understanding residency patterns and space use of a species is key to the implementation of effective conservation and management practices. The characterization of movement patterns of species within an ecosystem can provide insight into why animals use particular habitats, such as for feeding or reproduction, and how movements are influenced by various biotic and abiotic factors. Furthermore, by describing the fine scale movements of a species within an ecosystem, patterns of habitat use, movement corridors, and focal areas can be identified, at both the population and individual level. These types of studies have historically been limited in polar ecosystems compared to lower latitude ecosystems, due to the logistical challenges of working in polar regions. In this study, we used a large acoustic telemetry array consisting of 83 receivers to study patterns of movement and residency of Arctic Skates (Amblyraja hyperborea) in Scott Inlet, Canada, a location of particular interest for the Canadian Government due to the impacts of climate change affecting the Arctic as well as its significance to the development of the community fishery for Greenland Halibut. (Reinhardtius hippoglossoides). Over the six years of this long-term acoustic telemetry study, we found that arctic skates exhibit variability in the residential behavior between males and females with females being detected at more consistent rates throughout the annual cycle while males exhibit increased detection rates between the months of April and November. Arctic Skates generally remained within or in the vicinity of Scott Inlet, exhibiting limited large scale movements away from the area, and showed strong site fidelity towards a secondary channel that runs perpendicular to the main Scott Inlet channel. This secondary channel also represented a key core activity area of the inlet for a majority of the skates. Due to the limited movement range and small activity space exhibited by the Arctic Skates, this population, and the species more broadly, may be at an increased risk for localized anthropogenic disturbances.

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.
