Seasonal variations in the epilithic diatoms of Koçan Falls (Erzincan, Turkey)
Bibliographic record
Abstract
The present study explores some physical and chemical parameters in the epilithic diatoms in the water samples obtained from two stations in Koçan Falls, Erzincan from March to November 2014. Over the course of the study, 19 taxa of epilithic diatoms were recorded. Diatom genera which had the highest number of species in the study period were Cymbella (4 species), Navicula (4 species), and Cyclotella (3 species), while the most significant diatoms in terms of prevalence and the size of their populations were found to be Cyclotella spp., Gomphonema spp., Navicula spp., and Nitzschia spp. Over the course of the study, diatoms exhibited the highest level of growth in spring and summer, when there was more light and temperatures were higher. Considering the presence of diatoms within epilithic algae communities in all seasons, it appears that diatoms are cosmopolitan and can be among the algae that are commonly found at all types of substrata. The data obtained from the epilithic diatoms of Koçan Falls were analyzed according to Shannon-Weaver Diversity Index and Sorensen Similarity Index.

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.
