Abstract: 4 figures. ["An apparatus is described for simulating the natural environmental conditions relating to large thallose lichens, to enable their rates of nitrogen fixation to be estimated using 15N2 enriched nitrogen gas." Long term 15N2 incorporation can be compared with short term acetylene reduction measurements.]
