Determinácia, šírenie a vplyv inváznych rastlín na prirodzené ekosystémy: príkladové štúdie na rodoch Centaurea, Fallopia a Solidago
Determination, spreading pattern and impact of invasive plants on native ecosystems: case studies on Centaurea, Fallopia and Solidago
Program: VEGA
Zodpovedný riešiteľ: RNDr. Skokanová Katarína PhD.
Annotation: The project aims to study taxonomically problematic and hardly distinguishable invasive taxa and cytotypes of Centaurea stoebe agg., Fallopia japonica agg. and Solidago canadensis agg. occurring in central Europe. By combination of biosystematic approaches (morphometrics, flow cytometry, chromosome counting) we will determine particular taxa and cytotypes. Thanks to extensive field survey and revision of herbarium specimens we will contribute to the knowledge on current and past distribution of F. japonica agg. and S. canadensis agg. in central Europe and cytotypes of C. stoebe agg. in mixed-ploidy populations. Further, we will analyse ecological demands of particular taxa and cytotypes and model their future potential spreading within the studied area. To reveal and to compare impact of invasive taxa of F. japonica agg. and S. canadensis agg. on natural biotopes we will use a combined approach including analyses of soil properties, seed bank, diversity of plants, fungi and molluscs in invaded biotopes.

Systematika a fylogenéza rodu Dermoloma v Európe a Severnej Amerike
Systematics and phylogeny of the genus Dermoloma in Europe and North America
Program: VEGA
Zodpovedný riešiteľ: Mgr. Adamčík Slavomír PhD.
Annotation: Dermoloma is insufficiently known genus of basidiomycetes classified in the order Agaricales (Agaricomycotina). More than 30 species are described worldwide, but only few of them are generally accepted. Opinions about morphological delimitation and number of the species are very variable in the current literature. Traditionally, up to eight species are recognised, although more than 30 European species were described. Our preliminary phylogenetic study suggest existence of more than 25 molecular operation units in Europe that probably represent independent species. Aim of the project is to define European and North American Dermoloma species by means of molecular and morphological methods and to assign them correct names. Fungi of the genus Dermoloma are essential part of grassland ecosystems and accordingly this project will deal with studies of environmental soil samples. We will look for suitable metabarcode for identification of species using next generation sequencing (metagenomics).
