“…But, this range was higher than in boreal environments (Kuusinen, 1996), probably in relation to specific climate conditions in cold regions. Indeed, the diversity data from the literature are not always comparable since the sampling methods used can sometimes lead to discrepancies between the observations (e.g., Kuusinen and Siitonen, 1998;Selva, 1994).…”

Evaluation of lichen species resistance to atmospheric metal pollution by coupling diversity and bioaccumulation approaches: A new bioindication scale for French forested areas. Ecological Indicators, Elsevier, 2017Elsevier, , 72, pp.99-110. <10.1016Elsevier, /j.ecolind.2016 b s t r a c tIn order to evaluate the metal resistance or sensitivity of lichen species and improve the bioindication scales, we studied lichens collected in eight plottings in French and Swiss remote forest areas. A total of 92 corticolous species was sampled, grouped in 54 lichen genera and an alga. Various ecological variables were calculated to characterize the environmental quality -including lichen diversity, lichen abundance, and Shannon index -, as well as lichen communities. Average ecological features were estimated for each study site and each of the following variables -light, temperature, continentality, humidity, substrate pH, and eutrophication -and they corresponded to lichen communities. Based on lichen frequencies, we calculated the index of atmospheric purity (IAP) and lichen diversity value (LDV). These two bioindication indices were closely related to lichen diversity and lichen abundance, respectively, due to their calculation formula. It appeared that LDV, which measures lichen abundance, was a better indicator of metal pollution than IAP. Coupling lichen diversity and metal bioaccumulation in a canonical correspondence analysis, we evaluated the resistance/sensitivity to atmospheric metal pollution for the 43 most frequent lichen species. After validation by eliminating possible influences of acid and nitrogen pollutions, we proposed a new scale to distinguish sensitive species (such as Physconia distorta, Pertusaria coccodes, and Ramalina farinacea) from resistant species (such as Lecanactis subabietina, Pertusaria leioplaca, and Pertusaria albescens) to metal pollution, adapted to such forested environment.

“…The plot with the highest value of 49 species, representing almost 20% of the total flora investigated, was located in this belt, too. Beside the suboceanic climate of this belt, forests with low anthropogenic influence (such as forest management and air pollution) promote a rich lichen flora (Rose 1976;Selva 1994). In contrast to the subalpine belt with the lowest overall species richness, Fagus sylvatica and Abies alba are frequent tree species along with the dominant Picea abies.…”

Abstract:To identify representative quantitative criteria for the creation of a future Red List of epiphytic lichens, 849 trees in 132 long-term ecological observation plots in the Swiss Central Plateau and the Pre-Alps were surveyed by standard sampling. Based on the trees, frequency data of the lichen taxa observed are described by the log series model, indicating the controlling effect of few ecological factors. Based on the plots, four classes of scarcity, each comprising 25% of the species, were established. As a contribution to the development of a national, representative survey of lichens, (/-diversity (species richness, species density) and p-diversity (dissimilarity) were calculated in terms of region, vegetation formation, vegetation belt and for their combinations. Differences in lichen diversity between the Central Plateau and the Pre-Alps were caused by the bigger elevational range in the Pre-Alps, which resulted in a higher species richness. a-Diversity of forest and non-forest were similar, whereas each vegetation formation showed one third of its species restricted to it. The contributions to the total lichen diversity of crustose, foliose and fruticose as well as of generative and vegetative species was calculated. Specific features along the altitudinal gradient of vegetation belts emerged: the percentage of crustose and generative lichens declined with every altitudinal step, increased in fruticose and vegetative lichens, and was the same m foliose species.( 1997 The British Lichen Society
