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 (2. časť): biosystematické štúdium kritických taxónov
Flora of Slovakia – Asteraceae family (Part 2): biosystematic study of critical taxa
Program: VEGA
Zodpovedný riešiteľ: RNDr. Hodálová Iva, CSc.
Annotation: The project is focused on taxonomic and chorological revision of selected representatives of Asteraceae family (tribes Cardueae, Eupatoriae, Heliantheae, Inuleae) in Slovakia or Central Europe, respectively. The main result will be publishing of the next volume of book series Flora of Slovakia, namely Volume VI/2 (Part 2). Each taxon (cca 140 species, 55 genera) will be treated in terms of nomenclature, morphology, karyology, ecology, and chorology. Identification keys (in Slovak and English), original drawings of plants and distribution maps will be also included. Results of the study of taxonomically complex groups from genera Centaurea, Colymbada, Cyanus and Helianthus will be published in separate papers. As part of the project we will published also a book with revised Slovak vascular plant names (Slovak Nomenclature of Vascular Plants; cca 25,000 headings) and anextended and supplemented electronic edition of the biographical dictionary Botanical Personalities of Slovakia (cca 630 personalities).

PLANTin – Votrelci medzi nami: Časovo-priestorová dynamika rastlinných invázií a ich nepriaznivý dopad na ekosystémy
Aliens among us: Spatio-temporal dynamics of plant invasions and their adverse impact on ecosystem
Program: APVV
Zodpovedný riešiteľ: Ing. Hrivnák Richard, PhD.
Annotation: Plant invasions are an ongoing process threatening biodiversity at the species, habitat and landscape levels. The unique composition of alien flora at a regional level is mainly influenced by climate and cultural factors. The proposed project focuses on the environmental background of plant invasions in Slovakia (covers a substantial part of the Western Carpathians and an adjacent part of the Pannonia) which has been studied in this region only marginally so far. Dynamics of plant invasions will be studied in riparian vegetation along rivers that play a dominant role in the natural spreading of invasive plants. Using time series of vegetation, seed bank, and soil properties, we will reveal spatio-temporal changes in riparian ecosystems which will be further linked with environmental and human factors. Based on field and revised herbarium data, we will reveal the ecological demands of model invasive plant groups (Fallopia japonica agg. and Solidago canadensis agg.) and estimate their potential distribution under current and future climate conditions. An integrative approach will be used to study the impact of plant invasions on semi-natural grasslands which represent the most invaded non-anthropogenic habitats in Slovakia. We will compare multiple-taxa diversity (plants, bryophytes, fungi – by environmental DNA sequencing, molluscs and soil invertebrates) in non-invaded plots and in plots invaded by F. japonica agg. or S. canadensis agg. Further analyses of soil properties, seed bank, microbial activity, and fungal trophic structure will shed light on changes of belowground ecosystem processes at studied plots. We will also conduct a field experiment to study the impact of invasive plants on the decomposition of leaf litter. Such a study with exceptionally broad coverage of taxonomic and methodological approaches will provide a unique look at the plant invasion process and enable us to reveal, besides general trends, also species or group-specific patterns
