Temporal Variation in Algal Communities in an Intermittent Pond
Bibliographic record
Abstract
ABSTRACT We examined the algal communities in an intermittent pond in southern Ontario, Canada, at one permanently wetted site and two that dried up. Samples were collected from decomposing leaves and from the water column from ice-out in April to late August. Most of the algae present were attached forms. While there were some differences at the genus level, both temporary and permanent sites were largely dominated by filamentous chlorophytes (e.g., Oedogonium genera) immediately after ice-out. Subsequent to this early season bloom, the communities became more taxon rich, with diatoms (especially Pinnularia spp.) predominating at the permanent site, which also supported the highest diversity (30 genera). At the genus level, the community composition at the intermittent sites were subsets of that found at the permanent site. Many of these genera are known to produce a gelatinous matrix, or have a partially gelatinous structure—both advantageous to surviving drought. Using cell counts, the Cyanophyta (Cyanobacteria) appeared to be the most important community constituents; however, biovolume showed that the Chlorophyta and Bacillariophyta were the dominant groups.

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.
