Response of plankton communities to whole‐lake Ca(OH)<sub>2</sub> and CaCO<sub>3</sub> additions in eutrophic hardwater lakes
Bibliographic record
Abstract
1. The impact of whole‐lake lime (slaked lime, Ca(OH) 2 , and/or calcite, CaCO 3 ) addition on plankton communities was evaluated in eutrophic hardwater lakes on the North American Boreal Plain. 2. Two lakes received a single treatment of lime (Ca(OH) 2 at 74 or 107 mg L –1 ), two lakes received multiple treatments with Ca(OH) 2 and/or CaCO 3 (5–78 mg L –1 ), and four lakes were untreated and served as reference systems. 3. Over the long‐term (> 1 year), phytoplankton biomass was reduced in multiple‐dose lakes, but not in single‐dose lakes. Cyanobacteria typically dominated the algal community in the years before, during and after lime treatment in both single‐ and multiple‐dose lakes. 4. In the single‐dose lakes, randomized intervention analysis showed no significant change in the biomass of zooplankton after lime addition.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
