- Abstract
The wetting burst, resaturation respiration and basal respiration in <em>Peltigera polydactyla, P. proetextata</em> and <em>Nostoc commune</em> has been examined using both infrared gas analysis and oxygen electrodes. The physical nature of the wetting burst is further confirmed by drying replicates in CO2-free air, after which the burst is eliminated. The data also shows that resaturation respiration is very dependent on prior events in the field. A prior fast drying rate produces higher resaturation respiration rates than does slow drying. However the length of time a lichen remains fully saturated is largely responsible for the amplitude of maturation respiration and induces a very evident seasonal component in <em>P. polydactyla</em>. The extent of carbon loss and its potential ecological impact is questioned.
