Abstract

fetched live from OpenAlex

Leymus chinensis was sampled in the two routes of different vegetation types at the five different altitudes(1000m-2000m) in Daqing Mountain region of Inner Mongolia in order to investigate the effect of altitude on its plasticity.The results showed that the plasticity of Leymus chinensis in biomass and rhizome morphological characteristic were significantly in response to altitude.The biaomass of Leymus chinensis,the total biomass of community,the biomass ratio of Leymus chinensis to community and the biomass ratio of rhizome to pogoniasis root increased with the increase of altitude.This means that altitude can change the biomass allocation.The change patterns of the biomass ratio of root to shoot were in a quadratic curve when the altitude increased,which decreased in the former three altitude,then were on the raise in the following ones.In morphological respect of rhizome,the length of ryizome and average internode were also significantly increased when altitude increased,but there wasn't significant difference in ramet distance.

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.

Not 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.
