The survey recorded over 3000 epiphytes from 334 trees (Fraxinus excelsior) representing 74 lichen, 14 moss, 7 fungal and 3 algal species. There was a significant inverse relationship between diversity and NO(x). Diversity declined where NO(x) exceeded 70 microg m(-3) and NO2 exceeded 40 microg m(-3), suggesting a phytotoxic effect. However, there was a significant positive relationship between NO(x) and lichen abundance due to the ubiquitous distribution of pollution tolerant species, mainly associated with eutrophication. A scale of lichen sensitivity to NO(x) has been derived.}, author = {Davies, L. and Bates, J.W. and Bell, J.N.B. and James, P.W. and Purvis, O.W.} } @article {495, title = {Changes in oak epiphytes monitored for 21 years along an air quality gradient into London}, journal = {Eurasap}, volume = {41}, year = {2001}, pages = {8-9}, author = {Bates, J.W.} } @article {498, title = {Effects of sulphur dioxide and ozone on lichen colonization of conifers in the Liphook forest fumigation project.}, journal = {New Phytologist }, volume = {132}, year = {1996}, pages = {653-660}, author = {Bates, J.W. and McNee, P.J. and McLeod, A.R.} } @book {496, title = {Bryophytes and Lichens in a Changing Environment.}, year = {1992}, publisher = {Clarendon Press}, organization = {Clarendon Press}, address = {Oxford}, author = {Bates, J.W. and Farmer, A.M.
