Development of Nestedness: Host Biology as a Community Process in Parasite Infracommunities of Yellow Perch (Perca flavescens (Mitchill)) From Garner Lake, Alberta
Bibliographic record
Abstract
Infracommunity data from 60 perch collected from Garner Lake, Alberta, in 1992 were examined to determine whether ontogenetic shifts in host diet or habitat could produce a nested subset pattern of infracommunity structure. The host by parasite matrix showed significant nesting. Host idiosyncratic temperatures, which are indicative of differing "biogeographic histories," were determined primarily by the presence of Ergasilus caeruleus in depauperate communities, or its absence in richer communities, and covaried positively with host age and the associated variables of host length, mass, and infracommunity richness. Idiosyncratic host temperatures did not differ significantly between male and female perch when the effect of age was controlled for by analysis of covariance. Although an ontogenetic diet shift can be ruled out as producing the observed nested pattern, it is possible that the observed nested subset pattern is the result of an ontogenetic habitat shift.
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.
