“…2 ). The preference of C. candelaris for drier habitats and the attachment of V. hemisphaerica to moderately moist habitats are suggested based on an overview of the data in the literature (Fabiszewski and Szczepańska 2010 ). According to Wirth ( 2010 ), both lichens are characterised by similar ecological indicator values, although the moisture value is somewhat higher for V. hemisphaerica.…”

To date, the lichens Chrysothrix candelaris and Varicellaria hemisphaerica have been classified as accurate primeval lowland forest indicators. Both inhabit particularly valuable remnants of oak-hornbeam forests in Europe, but tend toward a specific kind of vicariance on a local scale. The present study was undertaken to determine habitat factors responsible for this phenomenon and verify the indicative and conservation value of these lichens. The main spatial and climatic parameters that, along with forest structure, potentially affect their distribution patterns and abundance were analysed in four complexes with typical oak-hornbeam stands in NE Poland. Fifty plots of 400 m2 each were chosen for detailed examination of stand structure and epiphytic lichens directly associated with the indicators. The study showed that the localities of the two species barely overlap within the same forest community in a relatively small geographical area. The occurrence of Chrysothrix candelaris depends basically only on microhabitat space provided by old oaks and its role as an indicator of the ecological continuity of habitat is limited. Varicellaria hemisphaerica is not tree specific but a sufficiently high moisture of habitat is essential for the species and it requires forests with high proportion of deciduous trees in a wide landscape scale. Local landscape-level habitat continuity is more important for this species than the current age of forest stand. Regardless of the indicative value, localities of both lichens within oak-hornbeam forests deserve the special protection status since they form unique assemblages of exclusive epiphytes, including those with high conservation value.

“…We used the ecological indicator values of lichens (Wirth ) as the best available information on the optima of ecological (realized) niches. For those species for which these values were not available, indicator values were designated according to information provided by Hallingbäck (), Wirth (), Thor & Arvidsson (), Dobson () and Fabiszewski & Szczepańska ().…”

Community response to alkaline pollution as an adjusting re‐assembly between alternative stable states

Aims We hypothesize that the community response to disturbances can be interpreted as a large‐scale dynamic equilibrium between multiple alternate states stemming from different species pools within a regional meta‐pool and being limited by species’ multi‐dimensional niches. We explore this hypothesis by examining the re‐assembly of an acidophilous lichen community in response to long‐term alkaline dust pollution, assuming understorey as a potential side‐factor. Location Around a cement factory in Kunda, Estonia. Methods Lichen communities on Scots pine (Pinus sylvestris) trunks in 40 stands around a cement factory and in nine distant limestone habitats were assessed. Results The formed bark pH gradient from pH 2.4 to 8.1 was reflected in a continuum of lichen communities on pines from acidophilous to basidophilous communities. Besides suppressing species richness, understorey density more evidently caused the compositional divergence from neutral bark conditions. The effect of hidden interactions among drivers was explained through reactions of individual species – almost all species across the pollution gradient were pH‐limited, whereas species adapted to neutral or alkaline substrate were additionally sensitive to understorey conditions. The hump‐shaped distribution of pH niche ranges along the observed niche optima, rather than ecological indicator values, showed that the shape of species’ multi‐dimensional niche‐space still needs to be quantified. Conclusions Each alternative community state along the disturbance gradient represents a realization of its specific species pool within the meta‐pool. Degradation can be defined if the community state is not supported by a meta‐pool. Species infiltration during community re‐assembly can be predicted using species source communities as cost‐efficient proxies.

“…The higher scale values correspond with increased either light intensity, concentration of nutrients or pH of the habitat. A small number of lichen species that have not been previously characterised by Wirth were described using a similar 5-degree scale proposed by Fabiszewski and Szczepańska (2010) developed for species common in Poland. Note that the value '1' on this scale refers to the first two levels on Wirth's scale and the adopted value in this case was '1.5'.…”

The Index of Atmospheric Purity (IAP) is a popular tool used for the assessment of air quality in polluted urban areas, on the basis of phytosociological data of epiphytic lichen communities. We hypothesized that this indicator could also be used in less polluted forest areas to determine the quality of ecological conditions for lichens. The aim of the present study was to verify the use of IAP method in the assessment of environmental pollution, and alternatively for the assessment of general ecological conditions in protected mountain forests of Gorce National Park (Polish Western Carpathians) based on the epiphytic lichen biota associated with Picea abies. The spatial distribution of IAP values on monitored sites in GNP was compared with: 1) spatial distribution of accumulated sulfur, nitrogen, selected heavy metals, and total heavy metals in Hypogymnia physodes thalli in 1993 and 2018 (30 sites), 2) mean ecological indicator values characterizing species requirements for light (L), substrate reaction (R) and nutrients (N), in 1993, 2013 and 2018 (33 sites). Generalized linear model and redundancy analysis were performed for disclosing most influencing factors affecting lichen communities. The study revealed a few negligible relationships between IAP values and accumulation of such elements as Ni, Mn, Cd, and Cr in both monitoring periods. Simultaneously, IAP can be useful for the identification of forest areas with a high degree of naturalness.
