Home is where you hang your bat: winter roost selection by prairie-living big brown bats
Bibliographic record
Abstract
Information on the roost requirements of small, temperate-zone hibernating bats, which can spend up to 8 months in hibernation, is crucial to their conservation. We studied male big brown bats (Eptesicus fuscus) in southeastern Alberta, Canada, to investigate the physical and microclimate characteristics of hibernacula used by this species in a prairie river valley (Dinosaur Provincial Park, DPP). We monitored roosting behavior and movement, and also compared microclimate conditions (temperature and humidity) within these crevice hibernacula to those of random crevices within the study area, and to conditions inside 4 known cave hibernacula in central and northern Canada. Our results show that male E. fuscus in DPP use rock-crevice hibernacula with less variable temperatures than ambient and random crevice temperatures, with evidence of winter roost fidelity within and between years. Bats used only 3 hibernacula and, although mid-winter flight is common in our study area, there was little movement by bats between hibernacula. Rock-crevice hibernacula were warmer and more thermally stable than other available crevices in DPP, and drier but not necessarily colder than known cave hibernacula elsewhere. Our study is the first to examine crevice roost selection by bats during winter, and suggests that specific hibernacula are important for individual bats, despite the fact that numerous crevices are available.

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.
