The Effect of Seasonal Vegetation Changes on Habitat Suitability and Predation Risk of the Vancouver Island Marmot
Bibliographic record
Abstract
Vancouver Island marmots (Marmota vancouverensis) are a critically endangered species with a small and fragmented population. They live in subalpine meadows, exclusively on Vancouver Island, Canada, but will also colonize logged habitats at lower elevations, which become population sinks for the species. Tree encroachment and vegetation shifts in these habitats are likely affecting seasonal vegetation cover and reducing the ability of marmots to visually detect predators, thereby increasing their risk of predation. Most marmot mortalities occur during the late summer, which may be related to peak vegetation growth during that period. This study assessed how these seasonal changes to vegetation in Vancouver Island marmot habitat is affecting habitat suitability and predation risk and involved the quantitative analysis of field data collected at the Mt. Washington marmot colony. Seasonal growth of herbaceous plant species significantly decreased line of sight visibility throughout active periods, likely decreasing marmots’ ability to detect predators. Climate change and shifts in alpine ecosystems are expected to reduce suitable habitat and increase predation risk for this threatened species.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
