Speciation in ancient lakes: Insights from the copepods of Sulawesi
Bibliographic record
Abstract
One of the fundamental questions in biology is the origin of species. Considerable insights into the processes that drive speciation have come from ancient lake systems. In this thesis, I present insights into speciation processes by investigating the species radiations of the ancient Malili Lakes of Sulawesi, Indonesia. The nature of adaptive radiations in the lakes suggests that intraspecific competition for extremely limited resources has driven taxa to adapt to specific habitats and food sources. The copepod populations of Sulawesi reveal that colonization order governs the geographic distribution of zooplankton in freshwater ecosystems. In many Malili Lakes taxa, hybridization between closely related lineages drives diversification, likely by increasing phenotypic diversity within populations. Furthermore, hybridization may be much more common in planktonic taxa than previously thought. Future research in these remarkable habitats is sure to reveal much about the role of hybridization and the origins of biodiversity on earth.

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.
