Effects of Spatial and Temporal Variation in Resource Availability on the Growth Rates and Survival of Dunlin (Calidris Alpina Hudsonia) Chicks
Bibliographic record
Abstract
Long-distant migrants nesting in the Arctic experience condensed breeding seasons and shorter periods of high arthropod availability due to climate change. Shorebirds have precocial chicks which may compensate for food shortages by responding to spatial and temporal variation in arthropod availability. I hypothesize that shorebirds capitalize on this mobility to select quality foraging habitats to maximize chick growth and survival. I monitored arthropod biomass during chick rearing in Churchill, Manitoba and East Bay, Nunavut to document variation in habitat use, growth and survival in relation to variation in arthropod biomass. Movements of Dunlin (Calidris alpina hundsonia) chicks were observed from hatch until fledging to investigate whether chicks responded to resource hotspots. Dunlin chicks, however, did not significantly respond to hotspots of arthropod biomass. Despite potential asynchronies between chick rearing and food resources from climate change, flexibility of foraging behaviour among Arctic-breeding shorebirds may contribute to reducing vulnerabilities for other 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.
