“…The predicted areas of suitability for acidophilous beech forests were mainly correlated with the interaction of precipitation and temperature, which is consistent with the ecological preferences known for these communities (Leuschner, Ellenberg, & Sutcliffe, 2017) and their predicted distribution at regional extents (e.g.…”

Aim We investigate whether (1) environmental predictors allow to delineate the distribution of discrete community types at the continental scale and (2) how data completeness influences model generalization in relation to the compositional variation of the modelled entities. Location Europe. Methods We used comprehensive datasets of two community types of conservation concern in Europe: acidophilous beech forests and base‐rich fens. We computed community distribution models (CDMs) calibrated with environmental predictors to predict the occurrence of both community types, evaluating geographical transferability, interpolation and extrapolation under different scenarios of sampling bias. We used generalized dissimilarity modelling (GDM) to assess the role of geographical and environmental drivers in compositional variation within the predicted distributions. Results For the two community types, CDMs computed for the whole study area provided good performance when evaluated by random cross‐validation and external validation. Geographical transferability provided lower but relatively good performance, while model extrapolation performed poorly when compared with interpolation. Generalized dissimilarity modelling showed a predominant effect of geographical distance on compositional variation, complemented with the environmental predictors that also influenced habitat suitability. Main conclusions Correlative approaches typically used for modelling the distribution of individual species are also useful for delineating the potential area of occupancy of community types at the continental scale, when using consistent definitions of the modelled entity and high data completeness. The combination of CDMs with GDM further improves the understanding of diversity patterns of plant communities, providing spatially explicit information for mapping vegetation diversity and related habitat types at large scales.

“…Floodplain forests are highly productive and biodiverse forest ecosystems that provide a variety of important ecological services including buffering of stream flow and improvement of water quality (Kozlowski, 2002;Schnitzler et al, 2005;Leuschner and Ellenberg, 2017). Trees in floodplain forests have access to both surface and groundwater to cover their water needs (Cunningham et al, 2011).…”

“…In Central Europe, the higher parts of hardwood floodplain forests are dominated by pedunculate oak (Quercus robur L.) (Leuschner and Ellenberg, 2017). Owing to their very fertile soils and the less frequent occurrence of floods, the majority of these forests have been converted to agricultural land in the last centuries (Hughes, 2003;Leuschner and Ellenberg, 2017). Remaining fragments of oak dominated floodplain forests in Europe are of crucial importance because of the multiple economic and ecological services they provide (Eaton et al, 2016;Leuschner and Ellenberg, 2017).…”

“…Gradients from the tree base to the crown in microclimate, pH, nutrient availability, CO 2 concentration and structural characteristics of the substratum strongly influence epiphytic cryptogam species richness and composition (Campbell & Coxson, 2001;Coxson, McIntyre, & Vogel, 1992;Hauck, 2011;Leuschner & Ellenberg, 2017;Ódor & van Hees, 2004;Pach & Podlaski, 2015). Chemical site conditions vary with height above the ground as the result of differences in exposure to the atmosphere, nutrient inputs from animals, concentration effects along the stemflow path, and vertical gradients in bark texture, which is in turn an important site characteristic itself (Kermit & Gauslaa, 2001).…”

Question Biodiversity surveys of epiphytic bryophytes and lichens on standing trees are mostly restricted to the lowermost 2 m, since sampling above this level is time‐consuming and therefore expensive. However, sampling only the stem base is likely to result in underestimation of forest epiphyte diversity, because microclimate and physico‐chemical site conditions, both of which vary with height above the ground, play important roles for poikilohydric organisms. We investigate variation in epiphyte diversity and composition along the vertical gradient in forests and discuss factors that may potentially account for height‐dependent distribution patterns. Location Montane primeval beech forest Havešová in the Carpathians, eastern Slovakia. Methods Ten circular plots, each 500 m2, were selected randomly in an area severely affected by windfall. Epiphytes were sampled along the stems of recently uprooted trees, from base to the canopy. Mean Ellenberg indicator values (EIV) for light, moisture, acidity and nitrogen availability were used as surrogate variables for environmental interpretation of compositional patterns for sampling segments of 2 m along the stem. Results By sampling only the lowest 2 m, 10% of the total bryophyte and 48% of the lichen species would have been missed. We detected systematic patterns of compositional variation for both groups along the vertical gradient. While pleurocarpous mosses and liverworts were mostly restricted to the stem base, acrocarpous mosses and crustose lichens occurred along the stem almost to the top. Foliose and fruticose lichens were concentrated at intermediate heights and in the upper canopy. Patterns of variation in EIVs suggested that increasing light availability, decreasing moisture and increasing inputs of acidic and nitrous substances are responsible for the compositional shifts along the vertical gradient. Conclusions Sampling only the stem base implies severe underestimation of the epiphyte diversity in temperate broad‐leaved forests. The middle and the upper parts of tree stems have distinctive compositions of epiphytic cryptogams, because microclimate and physico‐chemical site factors vary with height above the ground.
