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.

To understand an evolutional route of the loss of the IP3 receptor gene, conservation of the IP3 receptor gene in algae was examined in silico based on the accumulating information of genomes and expression sequence tags. Results clearly demonstrated that the lack of the gene was observed in Rhodophyta, Chlorophyta except for Volvocales and Streptophyta. It was therefore hypothesized that the plant IP3 receptor gene was eliminated from the genome at multiple occasions; after divergence of Chlorophyta and Rhodophyta and of Chlorophyta and Charophyta.

Ponds are highly dynamic and challenging environments and display a wide range of trophic conditions. In farms affected by vibriosis, phytoplankton biomass and composition are highly variable. These conditions may promote the development of harmful algae increasing shrimp susceptibility to bacterial infections. Phytoplankton compartment before and during mortality outbreaks was monitored at a shrimp farm that has been regularly and highly impacted by these diseases.

Porém, algumas pessoas/instituições foram fundamentais nestes quatro anos de doutorado, sendo imprescindível agradecê-las nominalmente: Aos meus pais, Euclinir e Lidia, por terem sempre acreditado em mim e por me incentivarem a continuar na área que escolhi. Agradeço imensamente pela melhor herança que uma pessoa pode receber que é o exemplo de humildade e dignidade que vocês têm.

    Jihočeská universita v Českých Budějovicích Přírodovědecká fakulta Bakalářská práce Heterocytozní sinice rodu Scytonema, Calothrix a Scytonematopsis z oblasti Great Smoky Mountains National Park, USA Jarmila Michálková Školitel: Doc. RNDr. Jan Kaštovský, Ph.D. České Budějovice 2014 MICHÁLKOVÁ, J. (2014): Heterocytozní sinice rodu Scytonema, Calothrix a Scytonematopsis z oblasti Great Smoky Mountains National Park, USA. [Heterocytous cyanobacteria from genera Scytonema, Calothrix and Scytonematopsis in Great Smoky Mountains National Park, USA., Bachelor thesis, in Czech] – University of South Bohemia, Faculty of Science, České Budějovice, Czech Republic, 68 pp. Anotace: The aim of this thesis was to isolate and morphologically determine heterocytous cyanobacteria of taxonomically obscure genera Scytonema, Calothrix and Scytonematopsis from samples collected in the Great Smoky Mountains National Park, USA. Optimal cultivation practices were used and five species were identified - Scytonema (Scytonema hofmanii, Scytonema cf. millei and Scytonema subgelatinosum), Calothrix (Calothrix fusca) and Scytonematopsis (Scytonematopsis sp.).
