Abstract
Aquatic fungi play key roles in organic matter decomposition and nutrient cycling, but the effects of lake conditions and food web interactions on fungal diversity are still largely unknown. Our study is the first to assess mycoplankton along a broad lake trophic gradient based on total phosphorus (TP) (2-2500 μg/L) using DNA metabarcoding data from 369 Canadian lakes. Zoosporic fungi, Chytridiomycota in particular, dominated mycoplankton assemblages. Mycoplankton diversity declined ∼15 % along the trophic gradient. Community composition varied the most between oligotrophic and hypereutrophic lakes, with pH, TP and water temperature as main drivers. Notably, mycoplankton communities showed stronger correlations with eukaryotic phytoplankton than with physicochemical variables, underlining the importance of phytoplankton hosts and substrates. Chytrid taxa associated with Chrysophyta in acidic lakes differed from those associated with Chlorophyta and Cryptophyta in lakes within agricultural lands. Overall, our study highlights the essential role of phytoplankton in shaping mycoplankton diversity and communities.

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 it
