Taxonomical studies on selected species of Russula sect. Xerampelinae

 
Principal investigator: S. Adamcík   Top

Scientific co-workers: S. Ripková (Comenius University in Bratislava, Faculty of Natural Sciences, Department of Botany)

Duration: 01/2008 - 12/2010
Grant agency: VEGA 2/0140/08
Key words: mycology, taxonomy, macrofungi, Russula

Project summary:
Members of the genus Russula are important ectomycorrhizal symbiots of woody plants and they contribute to ecological stability of forest ecosystems. More than 200 species are known from the area of Europe and members of the genus are much more numberous worldwide. The project emphasis to the taxonomical studies of selected members of Russula sect. Xerampelinae (Russulaceae, Basidiomycota, fungi). Morphological studies of recently collected material are the most important part and comparison of results with studies on type and other original material of known taxa. The measured data will be statistically evaluated and compared with sequences of DNA.

Goals of the project:
The main aim is to morphologically delimitate taxa associated with oak, to specify valid names and synonymy and to designate types. Other important aim is to verify morphological and genetic homogenity of Russula faginea and R. clavipes.

Results:
Material recently collected from Europe, North and Latin America has been classified to the morphological groups based on microscopical observations. Delimitation of the morphological groups has been verified by molecular studies on several genes of DNA. The studies include also observations on original material of all known representatives of the section. In total, 16 American and 9 European members of the Russula sect. Xerampelinae have been recognised. Only 6 of American species have been identified with previously described taxa. The studies have not confirmed occurrence of any European species in the area of America. Several species considered as related have been excluded from the section based on studies on original material and, moreover, several of them have been identified with recently collected material. One American species Russula texensis has been described as new for science and other 9 prepared for publication. Except of improvement of delimitation of known European taxa, two additional species R. amemoides and R. nuoljae (not accepted in the recent literature) have been recognised.

Key words: botany, mycology, taxonomy Oomycetes, Ascomycetes, Basidiomycetes, Deuteromycetes

Project summary:
The goal of this project is the study of species spectrum, variability and chorology of selected taxonomic groups of phytopathogenic fungi and their host plants in Slovakia. The basic taxonomicaly-chorological research of the natural vegetation of phytopathogenic micromycetes on the Slovak territory will contribute to the knowledge on species and genus diversity of selected fungi Oomycetes, Ascomycetes, Basidiomycetes and Deuteromycetes (Taphrinales, Erysiphales, Exobasidiomycetes, Uredinales, Ustilaginales, Hyphomycetes) of the studied area. The taxonomical revision of problematical polymorphic groups will be realized, including nomenclature, typification, morphometrics and distribution of differentiated taxa. The study will be focused on selected species of microscopic fungi of the mentioned taxa, their occurrence and distribution in Slovak territory will be elaborated.

Scientific goals:
Creation of annotated checklist of micromycetes taxa and their hosts (including localities) from selected areas in Slovakia.

Species structure of lichens as important biodiversity components of selected areas in Slovakia

 
Principal investigator: A. Guttová   Top

Research team: A. Lackovičová, E. Lisická, I. Pišút

Duration: 01/2007 – 12/2009
Grant agency: VEGA 2/7068/27

Synopsis of the project:
The project is targeted to complex research of lichens, species structure, taxonomic questions and phytogeography within selected areas in Slovakia. Substantial contribution of the project is acquisition of unique information on lichen species structure. The information will be gathered by personal field work. All relevant historical entries on the occurrence of lichens will be summarized as a complement to the knowledge of total lichen diversity within the selected areas. Significant contribution from lichenological viewpoint will be to solve relevant taxonomic problems, which will refine hitherto knowledge on representation of particular species in Slovakia. The obtained results will be applied for habitat status assessment in Slovakia and for solving of further obligations of Slovakia resulting from its memeberhship in European Union.

Goals: 1st period

  • assessment of standing representation of particular components of lichen-flora in selected areas in Slovakia
  • safeguard complementation of distributional data of components of lichen-flora in selected areas in Slovakia
  • clarifying actual taxonomic problems and relevant nomenclatorial inacuracies
  • refinement of territorial borders of phytogeografically specific taxa
  • summing up the occurrence of lichens on some anthropogenic substrates
  • preliminary summaries of gathered results, standardisation of result compilation, drawing up drafts of the manuscripts of scientific studies

Goals: 2nd period

  • follow-up data completion (distribution of particular components of lichen-flora in selected areas in Slovakia)
  • synthesis of gathered data and their analysis with an emphasis on identification of species structure
  • result processing, drawing up manuscripts of scientific studies and submission of manuscripts to home and away scientific journals
  • drawing up manuscript of monographs

Lowland and submontane bryophyte flora and bryocoenoses
in Slovakia – present state and threat

 
Principal investigator: A. Kubinská   Top

Scientific co-workers: K. Janovicová, K. Kresáňová, R. Šoltés

Duration: 2007 – 2009
Grant agency: VEGA 2/7070/27
Key words: bryophytes, Slovakia, biodiversity, bryocoenosis

Project summary:
Since the habitat protection is a presumption for the bryophyte conservation policy, the mapping of bryologically important habitats is crucial, especially ancient forests, wet meadows and peatlands, agrocoenosis and biorefugia in urbanneous environment. While studying the chorology, ecology, biology and phenology, the investigation will be focused on the species included in the Appendix I of the Bern Convention, Habitat Directive, on the European important species, relic and endemic species of Slovakia.

Scientific goals:
The submitted project includes 3 main goals

  • Monitoring and mapping of bryologically important habitats in selected areas of Slovakia– Borská nížina lowland, Podunajská nížina lowland and Spišská Magura Mts;
  • Distribution of poorly known and rare bryocoenoses, especially hygrophilous, epiphytic, epixylic and antropogenous bryophyte communities;
  • Chorology and dynamics of rare and endangered bryophytes.
