“…Both physiological data (Gauslaa and Solhaug, 2000) and distributional data at multiple spatial scales (McCune, 1993;Goward and Arsenault, 2000;Sillett and Antoine, 2004) have shown that epiphytic cyanolichens tend to be dependent on high moisture conditions, and intolerant of high light conditions. Thus, forest harvesting is likely to affect the cyanolichen communities of the inland rainforest indirectly by forest fragmentation, as well as directly by removal of their substrates.…”

“…Distributional data at multiple spatial scales have shown that cyanolichens are less tolerant of desiccation than chlorolichens (containing only green-algal photobionts) (Sillett and Antoine, 2004). In British Columbia, cyanolichen diversity on conifer branches increases along a gradient of increasing summer precipitation (Goward and Arsenault, 2000).…”

“…Key factors at a tree scale include tree species, canopy height, branch size, tree age, and nutrient availability (Esseen et al 1996;Ellis 2012). Important stand factors include horizontal and vertical distributions of the canopy, stand age, and microclimate (Coxson and Coyle 2003;Sillett and Antoine 2004).…”

Broad-scale distribution of epiphytic hair lichens correlates more with climate and nitrogen deposition than with forest structure

Hair lichens are strongly influenced by forest structure at local scales, but their broad-scale distributions are less understood. We compared the occurrence and length of Alectoria sarmentosa (Ach.) Ach., Bryoria spp., and Usnea spp. in the lower canopy of > 5000 Picea abies (L.) Karst. trees within the National Forest Inventory across all productive forest in Sweden. We used logistic regression to analyse how climate, nitrogen deposition, and forest variables influence lichen occurrence. Distributions overlapped, but the distribution of Bryoria was more northern and that of Usnea was more southern, with Alectoria's distribution being intermediate. Lichen length increased towards northern regions, indicating better conditions for biomass accumulation. Logistic regression models had the highest pseudo R 2 value for Bryoria, followed by Alectoria. Temperature and nitrogen deposition had higher explanatory power than precipitation and forest variables. Multiple logistic regressions suggest that lichen genera respond differently to increases in several variables. Warming decreased the odds for Bryoria occurrence at all temperatures. Corresponding odds for Alectoria and Usnea decreased in warmer climates, but in colder climates, they increased. Nitrogen addition decreased the odds for Alectoria and Usnea occurrence under high deposition, but under low deposition, the odds increased. Our analyses suggest major shifts in the broad-scale distribution of hair lichens with changes in climate, nitrogen deposition, and forest management.Key words: climate change, epiphytic lichens, forest structure, nitrogen deposition, temperature.
