“…Z kolei Krzewicka i Galas (2006) prowadziły badania nad wymaganiami siedliskowymi dwóch gatunków z rodzaju Verrucaria w Tatrach, uwzględniając wielkość kamieni i głazów preferowanych do zasiedlania przez te taksony, jak i głębokość zanurzenia plech w wodzie. Cieki wodne w ostatnich latach stały się przedmiotem zainteresowań lichenologów (Kiszka 1998a, b;Krzewicka & Hachułka 2008;Hachułka 2011;Matura & Krzewicka 2015;Matura 2016; Krzewicka i in. 2017).…”

The study presents the results of lichenological research conducted in 2012–2016, based on my fieldwork carried out in mountain streams in the Polish Western Carpathians, revision of herbarium materials, and published data on lichen species in freshwater habitats in the study area. Field work was performed on 98 research plots divided into three zones related to duration of immersion (294 sampling sites in total). As the result of the work, 94 freshwater lichen species were found (91 based on my field work and/or revision of herbarium material), including 56 aquatic species. For all species, detailed descriptions of morphological and anatomical characters, information on their habitat, occurrence in the study area, worldwide and country distribution, and brief taxonomic notes are given. A key for species identification is also provided. From the present lichenological study, Verrucaria acrotella is reported as new for the Polish Western Carpathians. In total, 30 new species were recorded in particular mountain ranges in the study area. New records of Sarcogyne privigna and Thelidium fontigenum, very rare species in Poland, are given. The streams of the Polish Western Carpathians are characterized by high species diversity in various mountain ranges. The richest lichen biota was observed in streams of the Tatra Mts, where 76 species were found, representing more than 80% of the total number of freshwater lichens known from the Western Carpathians. In the Beskidy Mountains, species diversity in the streams remains within the range of 38–46 species. Two mountain ranges are distinguished by the presence of more species: the Beskid Sądecki Mts (60) and Beskid Żywiecki Mts (57). Thirtysix taxa were noted in the Carpathian foothills. A frequency analysis of lichens shows that very rare species (38 taxa; 40%) and rare species (32; 35%) dominate in the study area. Frequent lichens are the poorest group in the Polish Western Carpathians, accounting for only 4 species (slightly over 4%). Of all the lichens noted in the study area, 34 (~36%) are on the red list of the lichens in Poland. In the case of Carpathian streams, the substrate and the duration of inundation seem to be the most important factors for the occurrence of freshwater lichens. The duration of immersion also affects the species distribution. The submerged zone was the least diverse, in the terms of both number of species and represented families. The only species found there exclusively in the submerged zone were Ionaspis lacustris, Sporodictyon cruentum, Staurothele fissa, Thelidium submethorium, Verrucaria devensis and V. pachyderma. The splash zone provides a habitat transitional between the submerged and riparian zones. Lichens in this zone are constantly exposed to frequent changes between periods of inundation and desiccation. In the splash zone, both species found in the submerged zone as well as those occurring in the riparian zone were found. Species typical for the splash zone included Bacidina inundata, Gyalidea rivularis, Thelidium fontigenum, T. pluvium, Verrucaria humida and V. sublobulata. The most diverse group of lichens was associated with the riparian zone. Many lichens found in this zone are terrestrial lichens commonly found in non-freshwater habitats. They are considered to be rare in aquatic and semi-aquatic habitats but frequent in terrestrial habitats.

“…Aquatic lichens, especially freshwater ones, are one of the least studied groups (Tierno de Figueroa et al 2013). The occurrence of species is usually reported, but rarely data on their habitat preferences and distribution are available (Rosentreter 1984, Gilbert 1996, Thüs 2002, Harada & Wang 2006, Nascimbene & Nimis 2006, Krzewicka & Hachułka 2008, Krzewicka 2009. Lichens constitute a symbiotic association of two units, a lichen-forming fungus (mycobiont) and an alga and/or a cyanobacterium (photobiont), forming a combined organism (Ahmadjian 1993).…”

Lichens associated with aquatic and semi-aquatic habitats are a specific ecological group of symbiotic organisms. Distribution patterns, especially those of freshwater lichens and factors determining their occurrence, are poorly recognized. The species richness and composition of lichens were studied in the splash and submerged zones of Carpathian mountain streams. Habitat parameters, including pH, water conductivity, dissolved oxygen content, silting and light intensity at sampling sites, were used in the analysis. The streams differed greatly in terms of the species composition; only three lichens (Thelidium minutulum, Verrucaria hydrophila and V. praetermissa) of the entire pool of 29 recorded species were found in all streams. This fact does not directly relate to the habitat parameters measured either at the level of individual streams or considering all the streams studied. Instead, the differences in the species composition of lichens increased with the geographical distance between streams, even locally. This means that the occurrence of lichens in mountain streams is strongly site-dependent and the variability in the habitat is of less importance for species presence. Presumably lack of effective natural vectors and weak dispersal ability are strong limiting factors for freshwater lichens. Nevertheless, increased ion concentration in water can considerably promote the development of the thalli of some species of lichens, as in the case of Verrucaria praetermissa, while it can be a limiting factor for others, as in the case of V. hydrophila.

“…It was found in the Szczawniczek stream on submerged stones in a sunny place at an altitude of 900 m. It is widespread in the mountainous regions of southern Poland, where it has many localities, especially in the Western Carpathians, where it occurs in nearly all mountain ranges [11]. This species was also recorded from lower altitudes at scattered localities in central and northern Poland [11,12]. In Europe, it is widespread from sea level to alpine areas [9].…”
