Impact of a Chytrid-related mortality event on a population of the Green and Golden Bell Frog <i>Litoria aurea</i>
Bibliographic record
Abstract
Chytridiomycosis is considered a key threatening process under Commonwealth legislation. Little is known of the impact of this pathogen within wild populations. The Green and Golden Bell Frog Litoria aurea is a threatened species that is thought to be affected by this disease. Here we present an example of a chytrid related mortality event within an apparently healthy population of this species. The individuals were found to be carrying chytrid and we suggest that this was the proximal cause of mortality. Monitoring was conducted across Sydney Olympic Park between 1998 and 2005. In a small group of ponds in 1999, 23 individuals were found dead with 17 of these confirmed to have died as a result of chytrid infection within a short period of time. However, the number of frogs located within the complex remained at similar levels for the duration of the monitoring program. Management of wild populations of the Green and Golden Bell Frog should maximise the area of available habitat for this species and the connectivity between habitats in an attempt to minimise the impact of disease outbreaks.

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.
