Phylogeography of the micro-endemic<i>Pedicia staryi</i>group (Insecta: Diptera): evidence of relict biodiversity in the Carpathians
Bibliographic record
Abstract
The Carpathian region is recognized as one of the most important hotspots for aquatic biodiversity in Europe. In the present study, 658-bp long nucleotide sequences from the mitochondrial cytochrome c oxidase subunit I (mtCOI) gene were used to study the phylogeographical patterns of the Carpathian endemic dipteran species belonging to the Pedicia staryi group. Molecular data support the taxon status of the allopatric sibling pairs of the morphologically highly similar Pedicia apusenica, Pedicia staryi, and Pedicia lobifera. This pattern is most likely the result of long-term isolation in so-called cumulative microrefugia in the Carpathians, caused by aridification and forest fragmentation in the Miocene-Pliocene period, in combination with the specific habitat requirements of these species (i.e. the wet and humid environments of forested headwater springs). Furthermore, molecular data reveal an important cryptic diversity in the case of the most wide-spread Carpathian P. staryi, as represented by highly divergent, allopatric populations from distant mountainous ranges, already recognized as important centres of endemism for aquatic insects. In addition, an unexpectedly high genetic diversity was identified in populations from the Rodnei Mountains, where the northern and southern slopes harbour highly divergent genetic lineages. This highlights the importance of this mountain range in the preservation of autochthonous diversity in the Carpathians. The present study provides important new evidence regarding the persistence of relic species in spring habitats in the Carpathians, with ancient divergence events that predate Quaternary glaciations and confirm their continuous presence during the Last Glacial Maximum in multiple isolated refugia, leading finally to a high genetic complexity in these particular aquatic ecosystems.

How this classification was reachedexpand
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.
