Molecular phylogenetics and biogeography of <i>Bunodera</i> spp. (Trematoda: Allocreadiidae), parasites of percid and gasterosteid fishes
Bibliographic record
Abstract
The genus Bunodera Railliet, 1896 is represented by five freshwater species: the holarctic B. luciopercae (Müller, 1776) in percids; the endemic North American B. sacculata VanCleave and Mueller, 1932 in percids; B. eucaliae (Miller, 1936) and B. inconstans (Lasee, Font and Sutherland, 1988) in freshwater sticklebacks; and the trans-Pacific B. mediovitellata Tsimbaliuk and Roytman, 1966 in the threespine stickleback (Gasterosteus aculeatus L., 1758). Partial sequences of the 28S ribosomal RNA gene were combined with morphological data for a phylogenetic analysis of Bunodera spp. Parsimony analysis of the combined data yielded a tree (consistency index = 0.84) that supports the following resolution: ((((B. luciopercae(((B. sacculata((B. mediovitellata(B. eucaliae + B. inconstans)))). The basal position of B. luciopercae is consistent with its holarctic distribution and a basal percid as its main host. The relatively basal positions of two typical perch parasites and the association of a more derived clade (B. mediovitellata + B. eucaliae + B. inconstans) with sticklebacks indicate host shifting from percids to sticklebacks. The sister relationships and North American endemicity of the two most derived species, B. eucaliae and B. inconstans, are also consistent with the more derived position of their typical host, the freshwater brook stickleback (Culaea inconstans (Kirtland, 1841)).
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.
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.
