Morphological and functional peculiarities of saltmarsh plants and epilithic lichens in tidal conditions of Russian Arctic Seas
Vol.4,No.2(2014)
Ecological plasticity in the tidal zone, specifically the effects of daily and seasonal dy-namics of environmental factors on the dominant species of vascular plants and epilithic lichens has been studied. 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.
