Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Lichens are keystone species ubiquitous around the world. Lichens are important air quality indicators across urban and natural ecosystems. The biodiversity of lichens can be great, but as species sensitive to air-pollution, the biodiversity in urban ecosystems does not always match the biodiversity of surrounding natural areas. For this work I used the citizen science tool iNaturalist to compile a list of the most frequently observed lichen species in the Portland-Vancouver Metro Region. Public tools like iNaturalist make lichen surveys accessible to more people. I present details about how to identify the five most frequently observed lichen species, and summary statistics about the twenty most observed species which span 11 fungal families. Parmeliaceae is by far the most common family representing 7 of the top 20 observed lichen species (35%), with Hypogymnia representing the genus of the most species (3 of 20). The most frequent type of thallus (lichen body) is foliose, representing 60% of the top observed species. I will give a brief overview of lichen biology and their ecology. Becoming familiar with lichens is the first step to promoting the conservation of these important organisms. The persistent nature of lichens enables the study of these organisms in any season. I aim to show that anyone can be a lichenologist.

Full frame distilled prediction

Teacher imitation

Not 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.
