Influence of Automobile Exhaust and Lead on the Oxygen Exchange of Two Lichens Measured by a New Oxispersion resulting from automobile emissions. Lead, added as an anti-knock agent in car fuel, has become the object of priority research for scientists and a contro versial issue for European political leaders. An estimated 100,000 tons of atmospheric Pb fall on to the Northern Hemisphere each year.

Photosynthesis, Water Relations and Thallus Structure of Stictaceae Lichens,phasis on leaf and canopy resistances. In recent years the adaptive significance of different photosynthetic pathways (C3, C4, CAM) has been extensively researched and, with this, water-use efficiency has become a central issue.

CO2 Exchange in Lichens: Towards a Mechanistic Model,ion, the enzyme activity of ribulose-1,5-biphosphate carboxylase, the enzyme controlling the incorporation of CO. should be measured... However, in practice it is much easier to measure CO. exchange, particularly when dealing with a whole plant or intact portion thereof.

In the maritime Antarctic, as the author has seen on King George Island, the abundance and variety of lichens is remarkable. In continental Antarctica, even near the coast of northern Victoria Land (Kappen, 1983b) lichens may be considered to be extremely resistant representatives of a pioneer veg
