Reflections on lichenology: achievements over the last 40 years and challenges for the future
Bibliographic record
Abstract
In June 2000, at the joint meeting of the Canadian Botanical Association and the Canadian Society of Plant Physiologists, the author of this review was presented with the George Lawson Medal for lifelong contributions to botany and was invited to prepare a special contribution for the Canadian Journal of Botany. Subsequently, an invitation was received to give the Swinscow Lecture to the British Lichen Society and the Linnean Society in London. This commentary is a written version of that January 2001 lecture and presents a personalized view of developments in those areas of lichenology studied by the author during a career in Canada and other parts of the world. Aspects touched upon include lichen identification, spore dispersal, nutrient transfer between the symbionts, water relations, and lichen strategies in particular climatic regions. The value of lichens for monitoring pollutants is noted, and the developing problem of lichen conservation is discussed. Finally, a plea is made regarding the value of field teaching and field excursions with respect to recruiting the next generation of lichenologists.Key words: lichens, asci, carbohydrate transfer, ecophysiology, pollution, old-growth forests, lichen societies.

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.
