Abstract

fetched live from OpenAlex

The distributions of Picea abies (L.) Karst. and other European forest trees have continuously changed since the last glaciation. Static and dynamic bioclimatic simulation models are used to estimate the degree of climatic control operating on the southern Scandinavian range limits of Picea during the last 1000 years. The results show that the range limit has begun to track climate change more closely than in the past, and a future projection predicts a rapid northward contraction of the present limit. Contracting ranges track climate change more closely than do expanding ranges that are limited by seed dispersal. The physiological mechanism of the climatic control is unclear, but Picea planted beyond its current climatic range limit was seriously damaged during a recent storm. Planting trees beyond their natural climatic range limits can only be advised in areas that become suitable for colonization under a changed climate.

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 distilled prediction

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.
