Fig. 4 — The relationship between thallus water holding capacity (WHC; from Gauslaa & Coxson, 2011) and permanent depression in F_v/F_m measured in this study as a percentage of the start values after a 7-d combined drying and light exposure ( = 0.469; P = 0.005). Open symbols, the chlorolichens Platismatia glauca (triangles apex up) and Lobaria pulmonaria (circles). Closed symbols, Pseudocyphellaria anomala (squares), Lobaria scrobiculata (triangles apex down), L. hallii (triangles apex up) and L. retigera (circles). Each error bar (vertical as well as horizontal) represents ± 1SE (n = 39–40 for WHC and n = 19–20 for F_v/F_m) from each type of habitat (see Table 3).
