“…New Zealand has a very rich assembly of Lobariaceae macrolichens, a family that has been identified as containing potentially excellent bioindicators of forest health (Rose 1974(Rose , 1976(Rose , 1992Galloway 1985Galloway , 1988Galloway , 1992Galloway , 2007Galloway , 2009Søchting & Christensen 1989;Gauslaa 1994;Selva 1994Selva , 1996Wolseley et al 1994;McCune 2000;Zedda 2002;Campbell & Fredeen 2004;Kalwij et al 2005;Jüriado & Liira 2009;Scheidegger 2009;Nascimbene et al 2010;Gustafsson et al 2013;Simijaca-Salcedo et al 2014;Cansaran-Duman et al 2015;Giorgio et al 2015;Ramírez-Morán et al 2016). However, despite the fact that New Zealand is currently regarded as the best studied area when it comes to the taxonomy of Lobariaceae (Galloway 2009), our results show that species delimitations are far from settled, which has implications for our understanding of species-level ecology.…”

We present a phylogenetic revision of the Sticta filix morphodeme in New Zealand. This non-monophyletic group of early diverging clades in the genus Sticta is characterized by a stalked thallus with a green primary photobiont and the frequent formation of a dendriscocauloid cyanomorph. Traditionally, three species have been distinguished in New Zealand: S. filix (Sw.) Nyl., S. lacera (Hook. f. & Taylor) Müll. Arg. and S. latifrons A. Rich., with two cyanomorphs separated under the names Dendriscocaulon dendriothamnodes Dughi ex D. J. Galloway (traditionally associated with S. latifrons) and D. dendroides (Nyl.) R. Sant. ex H. Magn. (traditionally associated with S. filix). Sticta lacera was not included in the present study due to the lack of authentic material (all specimens originally identified under that name and sequenced clustered with S. filix); S. filix was confirmed as a distinct species whereas S. latifrons s. lat. was shown to represent two unrelated species, S. latifrons s. str. and the reinstated S. menziesii Hook. f. & Taylor. The cyanomorphs of S. filix and S. latifrons are not conspecific with the types of the names D. dendriothamnodes and D. dendroides, respectively; the D. dendriothamnodes cyanomorph belongs to the Australian taxon Sticta stipitata C. Knight ex F. Wilson, which is not present in New Zealand, whereas the D. dendroides cyanomorph corresponds to a previously unrecognized species with unknown chloromorph, recombined here as Sticta dendroides (Nyl.) Moncada, Lücking & de Lange. Thus, instead of three species (S. filix, S. lacera, S. latifrons) with their corresponding cyanomorphs, five species are now distinguished in this guild in New Zealand: S. dendroides (cyanomorph only), S. filix (chloro- and cyanomorph), S. lacera (chloromorph only), S. latifrons (chloro- and cyanomorph) and S. menziesii (chloro- and cyanomorph). A key is presented for identification of the chloromorphs and the dendriscocauloid cyanomorphs of all species. Semi-quantitative analysis suggests that species in this guild are good indicators of intact forest ecosystems in New Zealand and that the two newly recognized species, S. dendroides and S. menziesii, appear to perform particularly well in this respect. The use of lichens as bioindicators of environmental health is not yet established in New Zealand and so, based on our results, we make the case to develop this approach more thoroughly.

“…The conservation of epiphytic lichens depends on the understanding of the main factors influencing their distribution, abundance, dispersal, establishment, growth and reproduction (Benesperi et al 2018). Lobaria pulmonaria is an indicator of valuable forest habitats (Nascimbene et al 2010(Nascimbene et al , 2013c and important sites for the conservation of cryptogamic species belonging to understudied groups (e.g., bryophytes -Scheidegger & Werth 2009, Brunialti et al 2015. In our case, to mitigate further potential damages due to logging, several Lobaria-trees and patches (islands) with uneven-aged trees were preserved in the investigated stand (Fačkovcová et al 2019), without a negative impact on the activity of woodcutters.…”

“…This fully applies to the epiphytic forest lichen Lobaria pulmonaria Hoffm., which has suffered a general decline throughout Europe as a consequence of global change and forestry (Otálora et al 2011, Nascimbene et al 2016, whose effects are expected to be further exacerbated by climate change (Nascimbene et al 2016). Its occurrence and abundance are used as indicators of forest ecological con-tinuity (Rose 1976, Nadyeina et al 2014 and for mapping forest sites worthy of conservation (Campbell & Fredeen 2004, Bergamini et al 2005, Nascimbene et al 2010, Brunialti et al 2015. Currently, L. pulmonaria is a red-listed species in several European countries (Scheidegger et al 2002, Krause et al 2017.…”

“…The negative effects of silviculture on L. pulmonaria were early reported at the beginning of the last century (Lettau 1912) and outstanding works summarize the interactions between different forest management practices and L. pulmonaria populations (Scheidegger & Werth 2009, Aragón et al 2010, Nascimbene et al 2013a, Brunialti et al 2015. Intensive forest management may threaten L. pulmonaria, and in general sensitive forest lichens, causing habitat fragmentation, degradation and loss, that impact local populations structure, size and dynamics (Scheidegger & Werth 2009, Benesperi et al 2018.…”

This study was conceived in March 2016, as soon as we were informed about an authorized logging for timber within a Mediterranean mixed oak forest in Tuscany (central Italy), which threatened a large population of the forest macrolichen Lobaria pulmonaria (L.) Hoffm., composed of hundreds of fertile thalli. Lobaria pulmonaria is often used as an ecological indicator of high quality habitats hosting rare lichens, and in general, cryptogams worthy of conservation. The species has suffered a general decline throughout Europe as a consequence of air pollution and intensive forest management, and currently it is red-listed in several countries, where it is considered also as a "flag species". We estimated that 40% of the lichen biomass (8.5-12.3 kg ha-1) has been lost due to logging operations (in the core area, up to 1.8 kg every 100 m 2), in particular large and fertile thalli. One year after the conclusion of logging operations, the analysis of chlorophyll fluorescence emission (indicator of the photosynthetic performance of the lichen photobionts), revealed a significant reduction of the vitality of the thalli on retained-isolated trees. The article provides issues for conservation in Mediterranean oak forests and outlines the outmost importance of ensuring the safeguard of forest ecosystems hosting fertile populations of this model species, especially in the case of unprotected forests.

Abstract:The population structure of the lichen Lobaria pulmonaria (L.) Hoffm. was analyzed in the Vodlozersky National Park (Karelia, Russia), for middle boreal forest stands having a time-since-disturbance spanning 80 to 450 years. To estimate the age of the last disturbance, a method of evaluation for the tree population structure was applied. The forest stand communities belonged to a successional series: middle-aged aspen -mixed aspen-spruce -pre-climax spruce -climax (old-growth) spruce forest. All thalli (1055) of L. pulmonaria from all substrate units (165, separately standing or lying trees and shrubs) were described within 7 sample plots of 1 ha. For each thallus, the area (cm 2 ) and the functional-age group were determined. The number of Lobaria thalli per ha, number of substrate units, number of substrate types (living, standing dead and lying dead trees of different species) colonized by L. pulmonaria, as well as number of substrate types on which the lichen had completed its life cycle increased with time-since-disturbance.
