Data for: Scale-dependent responses of understory vegetation to the physical structure of undisturbed tundra shrub patches
Bibliographic record
Abstract
These data were collected in order to explore relationships between the physical structure of tundra shrubs and local vegetation and abiotic conditions. In order to do this we established 3 x 3 m sampling plots at the top, middle, and bottom of ten Alnus alnobetula (green alder) patches. All patches were situated on south-southeast facing hillslopes within 2 km of the Tail Valley Creek Research Station. Within each of these plots we selected two sub-plots for vegetation community composition. We also measured several abiotic variables within 50 cm of each 3 x 3 m plot. At each patch a 9 m belt was established from 13 m above the top edge to at least 12 m below the bottom edge, encompassing all 3 x 3 m sampling plots. Within this belt we mapped the relative location of all mature alder individuals and recorded their height and canopy width. These data were used to derive the structural data associated with each sampling plot and the data used for analysis of topographic trends in structural characteristics.
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.
