Severe photobiont injuries of lichens are strongly associated with air pollution
The photobiont ultrastructure of the epiphytic lichens Bryoria fuscescens and Bryoria fremontii was studied along the pollution gradient from two Cu‐Ni smelters in Nikel and Monchegorsk in northern Finland and north‐western Russia. The relationship between ultrastructural characteristics of B. fusce...
