Growth and vitality of epiphytic lichens : II. Modelling of carbon gain using field and laboratory data.

 Photosynthetic and respiratory CO gas exchange was measured under controlled climate conditions in the laboratory in two epiphytic lichens, Lobaria pulmonaria and Platismatia glauca, with the aim of modelling their net productivity using field microclimate data. For both, the thallus water content (WC) and the light intensity had the greatest impact on photosynthesis. L.

Growth and vitality of epiphytic lichens : I. Responses to microclimate along a forest edge-interior gradient.

 We tested the hypothesis that changed microclimate at induced forest edges causes reduced growth of epiphytic lichens. Two foliose, green algal lichens were transplanted to the lower canopy of a mature Picea abies forest at six distances (2, 6.25, 12.
