The lichens of forest rocky communities of the hill Muroigora (Arkhangelsk Region, Northwest Russia)

Thirty-one lichen-forming fungi, 12 lichenicolous fungi, and 5 non-lichenized fungi are reported as new for Arkhangelsk Region; 7 species are new for its mainland area. Micarea fallax is reported for the first time for Russia; M. laeta and M. pusilla are new for the European part of Russia. The second finding of Nicropuncta rugulosa for Russia is recorded; microconidia are first observed in this species. The records of ten species which have been included in the new edition of the Red Data Book of the Arkhangelsk Region (2020) are presented. Nephromopsis laureri from the Red Data Book of the Russian Federation (2008) and Leptogium rivulare from the IUCN Red List are reported for the first time for Arkhangelsk Region.

“…Our earlier publications (Tarasova et al, 2015(Tarasova et al, , 2016 contain detailed overview of history of lichenological studies in the territory of Arkhangelsk Region. Currently, diversity of lichens and allied fungi in Arkhangelsk Region is becoming increasingly studied (Konoreva et al, 2019b;Tarasova et al, 2019).…”

“…Continued lichen inventories are necessary to increase knowledge about the biodiversity of such an reference area with high conservation value communities. The lichen studies on the ridge Windy Belt began recently, nonetheless, they have revealed a high species diversity (269) of lichens and allied fungi in this area (Tarasova et al, 2015(Tarasova et al, , 2016. For example, the oceanic lichen Platismatia norvegica was found on the ridge top (Olovgora Mountain) for the first time for the territory of the European part of Russia (Tarasova, 2014).…”

The paper presents the results of continuing research of lichen diversity in rocky communities of Windy Belt Ridge (Arkhangelsk Region, NW Russia). Using the method of sample plots and linear routes, the communities of the mountain Vysokaya (Volda) were examined, and 270 species and 2 subspecies of lichens and allied fungi were recorded there. A total of 18 lichens are new for the mainland area of Arkhangelsk Region, 35 species are new to the Vodlozersky National Park (Arkhangelsk part) and 9 species are in the Red Data Book of Arkhangelsk Region (2020). Within sample plots (altogether 0.2 ha), 230 species were found, with 41–50% of total species number being presented within one sample plot (0.04 ha). Along the linear route (2 km), 190 taxa were recorded: 43 species were found only on the route (outside the sample plots), which is 16% of the total lichen species number in studied communities. Comparative analysis of the lichen diversity between currently studied mountains (Olovgora, Muroigora, Vysokaya) of the Windy Belt Ridge showed that the high degree of community conservation, rocky type of communities with significant rocky outcrops, as well as landscape heterogeneity determine conditions for a high species diversity of lichens. In total, 343 species of lichens and allied fungi have been found for the studied mountains of the Windy Belt Ridge.

“…Recently 188 species were also reported from the Muroigora, which is located in the Arkhangelsk portion of the Park (Tarasova et al, 2016).…”

The population structure of the lichen Lobaria pulmonaria in the middle boreal forests depends on the time-since-disturbance

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.
