Comparative limnology of lakes in the Southern Rocky Mountain Trench, British Columbia
Bibliographic record
Abstract
Within a restricted geographical area of British Columbia, a detailed examination was conducted in I960 and 1961 of 9-lakes having similar morphometric and climatic influences, but exhibiting a wide dissolved nutrient range (50 to 1460 ppm). Attempts were made to relate total dissolved solids as well as other chemical and physical indices, to biological factors indicating or influencing lake productivity. Measurements were made of standing crops of plankton, bottom fauna and fish as well as hypolimnial oxygen deficits, sedimentation rates and gross primary productivity. Standing crops of plankton appeared related to oxygen deficits and perimeter to area ratios. Furthermore, total dissolved solid content correlated with gross primary productivity estimates based on Light and Dark Bottle techniques. Total dissolved solid content of lakes was not correlated with standing crops of plankton, bottom fauna or fish. Ranking of selected physical or chemical indices of productivity failed to agree with ranking based on standing crops or other biological measurements of productivity. A number of possible factors which interact to modify the expression of primary correlates of productivity are discussed.
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.
