Use of lichen as a roosting substrate by<i>Perimyotis subflavus</i>, the tricolored bat, in Nova Scotia
Bibliographic record
Abstract
Abstract: An apparently disjunct population of tricolored bats (Perimyotis subflavus) exists in southwest Nova Scotia. During the summers of 2003–2004 and 2007–2008 we trapped bats in mist nets set at a bridge over the Mersey River in Kejimkujik National Park. In total we captured 42 tricolored bats (41 female and 1 male) and fitted 32 females and the single male with radio transmitters and tracked them to their roost sites daily. Characteristics of roost sites were compared to those of randomly selected, potentially available roost sites using an a priori—selected candidate set of models and ranked using AICC for model selection. In total we found 99 unique roost trees in 9 spatially distinct (8 female, 1 male) roosting areas. On average, bats spent 2.5 d in a roost tree. While conspecifics from other parts of the species' range typically roost in tree foliage, maternity colonies of tricolored bats in Nova Scotia roosted exclusively in Usnea trichodea lichen, typically in conifers (of which 91% were spruce; Picea spp.) that were on average 212 m from water. Only 4% of the 300 random trees from the landscape contained Usnea trichodea. These trees were a mixture of softwood and hardwood (58% and 42%, respectively) and were, on average, 550 m from water. These findings represent an apparently unique relationship between lichens and bats that likely impacts many aspects of the species biology, including distribution, social structure, and parasite prevalence.

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.
