Advancing Understanding Of Invasion Ecology With Pines
Bibliographic record
Abstract
Pine species have been introduced around the world for timber, soil stabilization and wind breaks. Selection for highly productive species and provenances has led to productive forestry but also to species that can readily spread and become invasive in otherwise productive pasture land, or biodiverse native grass- or shrub-land. Our research uses Pinus contorta as a model species to investigate mechanisms that underpin invasion ecology. Our international network of field sites enables us to compare native (USA and Canada), introduced and invaded ranges (New Zealand, Chile and Argentina). In order to disentangle the relative effects of genetics, abiotic nutrients and microbial community on seedling growth we performed an experiment that combined sterilization treatments, provenances and measurements of soil nutrients and fungal communities of soil and roots while keeping environmental conditions stable in a growth chamber u2018home-versus-awayu2019 design. Our research allows us to compare multiple hypotheses at once, advancing understanding of invasion ecology.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
