“…For example, in a study involving also some of the sites considered in this paper, Dirnböck et al (2013) found that "in European forests oligotrophic species are decreasing in cover, although a decline in species richness is not yet detectable". Similar results were obtained for lichens by Giordani et al (2014). In this paper, however, we concentrate on N deposition effects on tree nutrition and growth and results will be discussed accordingly.…”

“…Species of Sticta play a crucial role in the calculation of Indices of Ecological Continuity for woodland habitats in the British Isles (Coppins and Coppins 2002), as well as in the Pacific Northwest in North America (Tønsberg and Goward 2001;Doering and Coxson 2010;Radies and Coxson 2004;Radies et al 2009). They also indicate very low levels of nitrogen deposit in forests throughout Europe (Giordani et al 2014) and were recently included in newly designed indices for air quality in the Pacific Northwest (Root et al 2015). However, the role of several ecological drivers (woodland extent and continuity, air pollution regime and climate) at regional scale and their interaction are complex, and no single and simple model can be designed to explain the composition and richness of epiphytic lichen vegetation, especially in the framework of climate change (Ellis 2012(Ellis , 2013.…”

In the framework of a worldwide project on the phylogeny of the lichen genus Sticta, dedicated sampling was performed in four regions of Western Europe, roughly along an east-west line between N 48°02′ E 07°01′ and N 52°01′ W 09°30′, ranging from France/Vosges to Ireland/ Kerry. Five clearly distinct ITS haplotypes were detected for isidia-producing species where only two were expected. Subtle anatomical and morphological characters, together with a strongly supported 4-loci molecular phylogeny, permit distinguishing, besides the easily recognized S. canariensis and S. limbata: 1) the two well-known S. fuliginosa and S. sylvatica, whose type collections have been carefully reassessed; the former is widespread in both hemispheres, while the latter is correctly identified only from continental Europe and the Andes in Colombia. The barcode ITS of S. fuliginosa differs by a single substitution from S. limbata (with a single exception), and the 4-loci phylogenetic tree does not resolve them as distinct lineages, most probably highlighting a very recent divergence and incomplete lineage sorting. 2) Three species that were formely included in S. fuliginosa: the resurrected S. ciliata Taylor, belonging to a complex group yet to be disentangled and occurring in the Neotropics, Africa, Macaronesia, and Western Europe, and two species described as new to science, S. fuliginoides, found in continental Europe, the Canary Islands, eastern North America, and Colombia, and S. atlantica only known from Ireland and the Azores archipelago. Molecular inferences demonstrate active divergence and dispersion within S. ciliata that may require recognition of further species. Fresh material can be identified with a morphological and anatomical preliminary key provided here. We propose that the taxonomy of all lichen species be urgently reviewed in the light of molecular data in an evolutionary context, particularly those used as bioindicators of environmental change and woodland management.

“…For example, found PCA scores derived from the ground vegetation at these monitoring plots to be related to tree diameter differentiation and basal area, while epiphytic lichen diversity was strongly correlated with the Clark-Evans index (Giordania et al 2014). However, the assessed indexes of forest structure may be limited in describing the complex requirements of different biota, which is still a major issue (Neumann & Starlinger 2001, Hinsley et al 2002.…”

On the European level, the implementation of sustainable forest management by specific criteria and indicators is strongly promoted by the Ministerial Conference on the Protection of Forests in Europe (MCPFE, now Forest Europe). Within this context, dead wood and certain features of stand structure are recognized as important preconditions for biological diversity of forests at stand level (Schäfer 2001, Larsson 2001, MCPFE 2003. In the last decades, biodiversity-oriented management practices have been proposed to increase the quantity of dead wood and the presence of veteran trees; these include prolonging the rotation period, leaving dead trees in forests or even creating artificial high stumps from living trees (e.g., Jonsell et al. 2004, Ranius et al. 2005, Abrahamsson & Lindbladh 2006, Keeton 2006, Bauhus et al. 2009).Because of its ecological importance and its role in C sequestration, surveys of dead wood have recently been included in most National Forest Inventories (NFIs) and monitoring programmes (e.g., Geburek et al. 2010, Corona et al. 2011, Weggler et al. 2012). However, protocols for dead wood assessment differ among European NFIs, and data are difficult to compare (Herrero et al. 2013). Schuck et al. (2004) analysed inventory methods for 22 countries and found differences among attributes measured, diameter thresholds and sampling design. Furthermore, there is also a need for standardized indices of stand structure, that have been shown by Neumann & Starlinger (2001) to be suitable indicators to asses biodiversityrelated aspects of forest management. Since, similar investigations with the aim of proposing methods for harmonizing results from NFIs and probably adjusting NFIs' field methods have been undertaken. These activities resulted in bridging functions for parameters among NFIs , McRoberts et al. 2009, Woodall et al. 2009, Rondeux et al. 2012.Up to now, the relationships between silviculture, stand structure, dead wood and other aspects of biodiversity have rarely been studied in an integrated manner on a large scale. This study investigates the relationships between dead wood and stand structure based on a survey at 90 intensive monitoring plots across Europe. The survey was carried out in 2004 on plots in the Czech Republic, Denmark, Finland, Germany, Greece, Italy, The Netherlands, Slovakia, Spain, Switzerland, and Ukraine. The objectives of this large-scale evaluation were to: (i) identify a sets of variables suitable to characterise dead wood structures and a set to characterise stand structures; (ii) detect the relations...
