“…Similar to other researchers, determination of lichen zones was based on tidal rhythm, the presence of marker species, and structure of lichen communities additionally. From zone 1 to 4 (from the waterline to land), the structure of the lichen community changes from simple mono-species groups (e.g., Verrucaria ceuthocarpa or Hydropunctaria maura in zone 1) to complex multispecies groups, which include lichens of different life forms (mainly non-halophytic species in zone 4) (Sonina 2012).…”

“…Due to larger diversity of habitats, six types of ecotopes were identified within these zones, which were inhabited mainly by eurybiont species. Sonina (2012Sonina ( , 2014, based on the analyzed literature as well as on the pairwise comparison of partial lichen flora in the zones on the coasts of the Barents and White Sea, suggested that the lichen cover of the coasts in the lichen zone 1 can be attributed to the azonal type of lichen flora (Table 1).…”

“…According to the author (Sonina 2012(Sonina , 2014, for the lichens of the lichen zone 1 on different continents, similar ecological and topographic conditions are formed (periodic flooding with salt water and the presence of rocky substrate on the coast) that are mostly related to tidal dynamics of the sea. During the researches in the African continent on the Atlantic coast of the Namib Desert the species lichen diversity was described, and the influence of stone surface exposure on lichen distribution was shown (Wirth et al 2007).…”

“…They occupy various ecological niches that are unsuitable for colonization by higher plants. Lichens have to withstand the strong effect of abiotic factors, such as fluctuations in solar radiation, waves and wind, daily drying and humidification cycles, contrasting temperature, and salinity (Markovskaya et al 2010;Sonina 2012). In the littoral zone, lichens need to adapt to the frequency of flooding with salt water, while in the supralittoral zone, lichens withstand irrigation with sea moisture and wave splash (Fletcher 1980).…”

Lichens are a symbiotic complex of autotrophic (algae, Cyanobacteria) and heterotrophic (fungi) components that have developed during evolution in coastal ecosystems in the process of adaptation of algae and fungi to terrestrial habitats. Lichens are highly adapted to extreme habitats including the littoral (or intertidal) zones of coasts. In this chapter, we present developmental stages of aquatic lichen investigations: freshwater and marine lichens. The issues of species diversity of coastal lichens, their ecology, and adaptations to the coastal marine environment are described. The leading factors affected the epilithic lichen cover of coasts, and freshwater habitats are at a distance from the waterline and substrate characteristics. Substrate characteristics, especially near the waterline, depend on the wave rhythm. On the coasts of freshwater bodies, four zones are recognized based on flooding duration and lichen ecology. Lichen zones of fresh and marine coasts are distinguished by their species composition: on sea coasts halophytes are predominant and on freshwater shoreshydrophilic lichens. Marker species of lichens were identified for each zone. For the littoral zone, the intrazonal structure of lichen flora was shown. In the adaptation of symbiotic organisms, such as lichens, both symbionts take part: mycobiont and photobiont. Morphological and structural adaptations are mainly associated with mycobiont variability: the presence

“…On rocky shores a variety of interacting factors across this gradient (e.g. salinity (Grube & Blaha 2005;Delmail et al 2013), light (Sonina 2012), grazing (Higgins et al 2015) and water availability (Kranner et al 2008)) have led to the formation of lichen 'zones'. These zones correspond to distinctive coloured bands that begin at the top of the regularly submerged intertidal (black) and pass through parts of the shore exposed to regular sea spray/splashing (orange), to the upper zone that is influenced only by sea spray/splashing during storms (grey), before extending to fully terrestrial (i.e.…”
