Yevhen Maltsev ECOLOGICAL FEATURES OF ALGAE COMMUNITIES IN FOREST FLOOR OF PINE PLANTATIONS OF DIFFERENT TYPES OF LANDSCAPES IN STEPPE AREA OF UKRAINE ISSN 2225-5486 (Print), ISSN 2226-9010 (Online). 3 Biological Bulletin 331 The steppe zone of Ukraine features a large variety of types of natural landscapes that together significantly differ in microclimatic, soil, hydrological and geobotanic conditions. Such a diversity of forest conditions affects not only the trees, but also on all biotic components of forest ecosystems including algae. Purpose of the study was establish systematic position of species, dominant and subdominant, leading families of algae for plantings in forest floor of pine plantations of the valley-terrace and inundable-terrace landscapes in steppe area of Ukraine. In general, in the forest floor of Samara pine forest marked 34 species of algae with 4 divisions, most of which related to green: Chlorophyta 22 (65%), Xanthophyta 8 (23%), Bacillariophyta 2 (6%) and Eustigmatophyta 2 (6%). Among the leading families of the greatest number of species belonged to: Pleurochloridaceae (7 species), Chlorococcaceae (5), Chlamydomonadaceae (4). During all studied seasons in base of algae communities were species resistant to extreme values of all climatic conditions. Total in forest floor of pine forest in Altagir forest marked 42 species of algae with 5 divisions: Chlorophyta - 23 (55 %), Xanthophyta - 9 (21 %), Cyanophyta - 5 (12 %), Bacillariophyta - 3 (7%) and Eustigmatophyta 2 (5%). Systematic structure of list species determine three family, which have the number of species in excess of the average number (2): Pleurochloridaceae, Chlamydomonadaceae and Myrmeciaceae. The base of algae community are moisture-loving and shade-tolerant species, which may be the result of favorable moisture regime. In the forest floor of pine plantings in forest floor of pine plantations of the valley- terrace (Samara pine forest) and inundable-terrace (Altagir forest) landscapes found 64 species of algae with 5 divisions, which are dominated by green algae - 37 species (58%), that exceed xanthophytes - 15 (23%), blue-green 5 (8 %), eustigmatofites 4 (6%) and diatoms 3 (5%). From an ecological point of view algal flora forest floor of studied plantings characterized by a predominance of species of soil-inhabiting algae from X-life forms.
