Method for Field Measurements of CO2-Exchange. The Diurnal Changes in Net Photosynthesis and Photosr respective habitats may lead to a better understanding of habitat preferences and species distributions. However, the necessary photosynthetic CO. exchange measurements are difficult to accomplish in the field. Thus, only a few examples of diurnal courses of photosynthetic CO. uptake by poikilohyd

Many data have been published from field and laboratory measurements on Signy Island, although much less about lichens (Lindsay, 1978; Hooker, 1980a,b,c)

Photosynthetic Capacity Changes in Lichens and their Potential Ecological Significance,. Because they lack stomata it is possible to control diffusive resistances for CO. both throughout short-term experiments and seasonally The expression of metabolic rates on a biomass (usually dry weight) basis is not complicated by significant growth during experiments. At least in ., photorespira

Studies on the Nitrogen Metabolism of the Lichens , and ,,w occur in symbiotic association with a variety of eukaryotes. Those which occur in symbiotic association are, almost invariably, N.-fixing heterocystous forms (see Stewart et al., 1980; 1983 for recent reviews). In this paper we will consider aspects of the fixation, transfer and assimilation of ni

Nitrogen Losses from Diazotrophic Lichens,ly investigations were concerned with the total input of nitrogen into an ecosystem and naturally follow the realisation that since a number of lichens contain a member of the Cyanophyceae they might therefore be capable of fixing atmospheric nitrogen. This valuable feature was first definitely demo
