Brodo, IM 1986: Interpreting chemical variation in lichens for systematic purposes. - The Bryologist89: 132-138. [RLL List # 128-11 / Rec.# 2468] Keywords: CHEMISTRY/ SYSTEMATICS/ INTERPRETATION/ REVIEW/ PROBLEMS
Abstract: 1 figure. [Application of chemistry to lichen systematics is inconsistent and many are reluctant to use chemical criteria because of "1) practical problems (e.g. difficulty in demonstrating certain compounds), 2) biological factors (e.g. chemical variation due to the nature of the lichen), and 3) philosophical differences (e.g. having to do with various species concepts and character weighting)."]
