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.

Flóra Slovenska – čeľaď Asteraceae (1. časť): biosystematické štúdium kritických taxónov
Flora of Slovakia – Asteraceae family (first part): biosystematic study of critical taxa
Program: VEGA
Zodpovedný riešiteľ: RNDr. Mereďa Pavol PhD.
Annotation: The project is focused on taxonomic and chorological revision of selected representatives of the Asteraceae family in Slovakia, or in the wider Central European region, respectively. The main result of the project will be the next series of multivolume work Flora of Slovakia, volume VI/2 (Part 1). Due to the high species richness of this family in Slovakia only its initial tribes, namely Anthemideae, Astereae, Caleduleae, Gnaphalieae, and Senecioneae (with about 50 genera and 165 species) will be addressed in the project. Each taxon will be treated in terms of nomenclature, morphology, karyology, ecology, and chorology. Important part of the publication will be the identification keys (in Slovak and English), original drawings of plants, and maps showing distribution of taxa in Slovakia. Special attention will be paid to taxonomically complex groups of the genera Achillea, Aster s. l., Senecio s. l., Solidago, and Tephroseris, where we plan more detailed systematic, biogeographic, and evolutionary studies published in separate papers.
