Abstract

fetched live from OpenAlex

The aim of this research has been to reveal the seasonal dynamics of lipids in freshwater ecosystem of Lake Bohinj (Slovenia).Different pools of lipids, ranging from natural seston, zooplankton and fish, were used to reveal the main lipid groups there and to reveal the trophic interactions and energy transfer across the food web within a growing season.Along with the improved techniques used to analyze the lipid classes, we tentatively indicated several compounds as potential taxonomic biomarkers.The results of the research on Lake Bohinj show that analyzed aquatic organisms are subjected to seasonal effects and they have distinct fatty acids' profiles by which can be detected down to the species level.In the second part of the thessis, the focus was on the recent discovery of polymethylene interrupted fatty acids in freshwater ecosystems, characteristic for invasive and native mollusks of the Laurentian Great Lakes (Canada).For the first time, the existence of these fatty acids was proven in freshwater molluscs and their transfer into higher trophic levels confirmed.

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.

Not 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.
