У доминантных видов в лишайниковом покрове супралиторали (Umbilicaria deusta, Umbilicaria torrefacta, Physcia caesia) в двух точках: Филипповские садки и бухта Кислая Большого Соловецкого острова, а также у вида Rusavskia elegans, доминирующего в лихенопокрове на стенах монастыря и прибрежных камнях на Филипповских садках, определено содержание фотосинтетических пигментов в талломах. Анализ содержания пигментов показал, что диапазон варьирования суммы хлорофиллов у исследованных видов в прибрежных экотопах составляет от 0,2 до 1,0 мг∙г–1 сухой массы, а каротиноидов – от 0,1 до 0,3 мг∙г–1. Наиболее высокие значения содержания суммы хлорофиллов и более значительные различия по содержанию каротиноидов выявлены у видов рода Umbilicaria. Низкие значения содержания как хлорофиллов, так и каротиноидов получены в талломах Physcia caesia. У вида Rusavskia elegans, обитающего на стенах мо...

The investigations were conducted on the Pomorian coast of the White Sea (Republic of Karelia) during two growing seasons (2012-2013). The studies of the morphological and anatomical characteristics of dominant individuals in the plant and lichen cover types have been made along the model transect through different substrate types. Determination of plasticity of plants and lichens was made by the method of Cornelissen exploiting coefficient of variation (CV). The obtained data showed that the investigated groups of vascular plants and lichens on the tidal zone on all measured morphological and anatomical parameters have a high level of plasticity

During 2009-11 years the lenthic ecosystems of Northwest of Russia (Karelia)-the second-largest lake in Europe-Onego Lake and the lothiс ecosystems-the rivers Suna and Lososinka, differing on level of their exploitation and water composition have been investigated. The state of pigment apparatus at 5 species of vascular plants-3 hydrophytes-Potamogeton crispus, Sagittaria sagittifolia, Nuphar luteum and 2 hygrophytes-Carex acuta, Carex visicaria-is analyzed. At Carex visicaria the change touches all parameters of the pigment apparatus while at Carex acuta the changes concern only the ratio of chlorophylls and do not influence on the values of light-gathered complex. At Nuphar lutea and Sagittaria sagittifolia the pigment apparatus only at underwater leaves has shown the significant response to change of Mg 2+ contents. The pigment apparatus of surface leaves at Nuphar lutea has not shown the significant answer to chromaticity of water. At Potamogeton crispus the contents of pigments in surface and underwater leaves decreased at the increase in the contents of nitrogen. The analysis of the general projective covering and floristic composition of lichen cover has shown, that with the increase in the water the nitrogen and phosphorus contents, the number of species of lichens decreases. Thus, the coastal plants and the lichen cover can be used for the express trainanalysis at specification of trophic characteristics of freshwater reservoirs of the north of Russia.

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

A total of 82 species are new for the mainland area of Arkhangelsk Region. The species Bryoria glabra has been reported for the first time for European Russia. Two recorded lichen species, Cladonia bellidiflora and Lobaria pulmonaria, are in the Red Data Book of Arkhangelsk Region. The occurrence of old-growth forests, high heterogeneity of conditions, presence of an altitudinal gradient and the proximity to the sea lead to the rich diversity of lichens in this area.

The distribution of epilithic lichens on the coasts was studied and zoning was suggested. Lichens on the coasts of the White and Barents Seas are clearly divided into two groups  halophytes (species in the upper intertidal zone regularly covered by sea water) and non-halophytes (species in the supralittoral zone that are not influenced regularly by sea water, but splashed during heavy storms). The number of species of epilithic lichens increases with the distance from the low-tide mark from 2-4 to 12-40. Four lichen zones were distinguished on the coast based on such criteria as the distance from the low-tide mark and the development of lichen cover

Schrader and U. deusta (L.) have been studied. The study took place on the supralittoral zone on the coast of the White Sea in two points: Kolezhma village and Keret village in 2014 and 2015. Ecological plasticity of mycobiont which contacts the environment and gives a niche to the photobiont have been revealed, based on the analysis of variance in the study of anatomical structures of two different types of habitats and between different samples of the same species. Coastal conditions provide favorable levels of humidity and light for the U. torrefacta and U. deusta species. This allows symbiotic organism to maintain a symbiotrophic balance due to the plasticity of the fungal symbiont which contacts the abiotic environment. At the same time these adaptation mechanisms do not include functional changes, s...

Morphological analysis of aboveground and underground parts of the clones was performed on virginal plants. Anatomical analysis of leaf sheaths of the current year shoots, rhizomes and adventitious roots was carried out. The viability of pollen was assessed by determining the relative share of normally developed and malformed pollen grains. The content of heavy metals was determined in the soil, sea water and plant samples. The study was carried out on a model transect in the littoral zone on three test plots representing the lower littoral; the middle and the upper littoral zones. Adaptation to wave and storm impact was manifested in a well-developed system of underground organs. In the lower littoral, underground part surpasses the aboveground vegetative organs in terms of the mass and the formation of mechanical ...
