Lichens of the Supraśl town (Podlasie, north-eastern Poland)

Abstract

A paper presents a list of 89 species found in Supraśl town (Podlasie, NE Poland). The investigations in the area of Supraśl were carried out in 2013-2014, on 41 research stands. Eighteen species are considered to be threatened in Poland. The lichens occur on all substrate types: soil, decaying wood, bark of all trees and shrubs species, boulders, concrete, foundation, mortar, plaster and bryophytes. Valuable components of the lichen biota belong mostly to the group of threatened species not only on the regional, but also on the national scale. There are: Anaptychia ciliaris, Pleurosticta acetabulum, Ramalina fastigiata and others.

Synecological structure of the lichen synusiae within forest natural reserves from the Moldavian Plateau (Romania)

“…The rhytidome of Quercus species is acidic (Laundon, 1963;Oran and Öztürk, 2012), but this situation is contrary to the preferences of Physconia enteroxantha for eutrophic substrata (Zedda and Sipman, 2001;Matwiejuk, 2008;Riddell et al, 2012). Grazing is the main source of eutrophication of lichen substrata in the Bădeana Forest Reserve (Sârbu et al, 2007).…”

Notes on the distribution of lichen biota of Podlasie. III. Nowosady village, Podlaskie province (north-eastern Poland)

“…This kind of climatic conditions would negatively influence the growth of lichens. The number of species established in Nowosady is poorer than in Białowieża (94 epiphytes lichen species) [7], Olsztyn (63) [2], Boćki (57) [6], Mielnik (47) [5] and Drohiczyn (43) [4].…”

“…Matwiejuk [6], for example, has observed 41 taxons from epixylic lichens in Boćki. In other towns and small localities on Podlaskie Province different number of epixylic lichens was observed: 26 species in Mielnik [5], 24 species in Białowieża [7], and only six species in Drohiczyn [4]. Kiercul [10] has observed 26 species representing this type of lichens in Klewinowo and 12 in Hermanówka [11].…”

“…In contrast higher species richness of epilithic lichens was noted in Boćki [6] and Mielnik [5] (38 species) as well as in Drohiczyn [4] and Białowieża [7] (32 and 24 species respectively). An interesting phenomenon of the present study is the tendency for colonization of atypical substrates such as eternit roof slates by lichen species Lecanora muralis and Phaeophyscia orbicularis.…”

“…The lichen species inhabiting smaller towns on Podlasie, like Drohiczyn [4], Mielnik [5], Boćki [6] and Białowieża [7] have been also described. The diversity of lichen biota of orchards in different towns has been studied in Slovakia, Italy and Poland [8], and in several Polish villages or rural areas, including Warmia Plain [9], Klewinowo [10] and Hermanówka [11].…”
