Abstract

fetched live from OpenAlex

:Forest expansion (afforestation) is one of the main vegetation changes currently observed in peatlands worldwide in response to natural and anthropogenic disturbances. We examined the relationships between plant and bird richness and frequency and extent of the forest cover in bogs of southeastern Québec to evaluate the impact of forest expansion on typical bog species. A total of 154 plant species and 36 bird species were recorded in the 16 peatlands studied (2-189 ha). Richness and frequency of ombrotrophic plant species were negatively associated with an increase in forest cover. Yet, minerotrophic and minerotrophic-ombrotrophic species did not appear to take advantage of this decline. Afforestation influenced bird species composition by altering the vegetation structure in all strata of the bogs (fewer mosses and shrubs, more trees) and by homogenizing the spatial distribution of plant communities (open patches progressively replaced by forested patches). Peatlands of southeastern Québec remain islands of boreal vegetation in a matrix of deciduous forests and agricultural fields, but afforestation appears to progressively reduce the diversity of peatland habitats. Afforestation does not imperil plant or bird species across their entire range, but it contributes to impoverishing regional biodiversity.

Teacher imitation

Not 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.
