Relationships of Phenological and Inter-Annual Landscape Dynamics with Biodiversity in Farmlands
Bibliographic record
Abstract
The response of eastern Ontario farmland species diversity to landscape dynamics was modeled at multiple spatial and temporal scales using metrics derived from MODIS and Landsat data in random forest and multiple regression analyses. For the seven taxa studied, significant positive gamma diversity responses to MODIS-derived start of season NDVI and its spatial coefficient of variation over 3 km ×3 km landscapes were found for beetles and birds. Butterfly diversity was positively related to mean growing season NDVI. Plant diversity was found to be greater in landscapes where the start of the growing season is earlier. Landsat data analysis found that beetle and plant diversity is lower when Tasseled Cap brightness increases and wetness decreases, while butterfly and bird diversity increased with increasing NDVI. Initial inter-annual analysis showed that variation in NDVI over the period of 1985-2011 was not related to biodiversity measured in 2011-2012; i.e. no effect of interannual landscape vegetation dynamics on biodiversity was found.

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.
