Abstract Aim Determining which traits predispose a species to become invasive is fundamental question of invasion ecology, but affect invasiveness in concert with other factors that need be controlled for. Here, we explore the relative effects biological plant and their distributional characteristics native range on success at two stages invasion. Location Czech Republic (for species); world alien species). Methods The source pool 1218 seed plants Central Europe was derived from flora...
The Pladias (Plant Diversity Analysis and Synthesis) Database of the Czech Flora Vegetation was developed by project team in 2014-2018 has been continuously updated since then.The flora section database contains critically revised information on vascular flora, including 13.6 million plant occurrence records, which are dynamically displayed maps, data 120 characteristics (traits, environmental associations other information), divided into sections (1) Habitus growth type, (2) Leaf, (3)...
Summary Štorchová, H., Hrdličková, R., Chrtek, J., Jr., Tetera, M., Fitze, D. & Fehrer, J.: An improved method of DNA isolation from plants collected in the field and conserved saturated NaCl/CTAB solution. – Taxon 49: 79‐84. 2000. ISSN 0040‐0262. A simple for genomic wild sampled remote areas is presented. The protocol combines leaf preservation with sorbitol extraction secondary compounds which often contain inhibitors Taq polymerase activity. obtained suitable random amplified...
We present the third edition of complete catalogue alien flora Czech Republic which follows 2002 and 2012 editions. It has been updated by incorporating new data collected over last decade reassessing current status taxa based on improved taxonomic ecological knowledge. All changes in taxon listing from version are documented explained an appendix. Based comprehensive sources, including recently developed Pladias database vegetation Archaeobotanical Database Republic, we list 1576 to this...
PREMISE OF THE STUDY: The phenotype of an individual can be modified by the environment experienced its predecessors, a phenomenon called transgenerational or maternal effects. These effects are studied mostly across sexual generations and thought to mediated also epigenetic variation. However, we do not know how important asexual clonal plants. METHODS: We investigated role different drought intensities durations parental plants Trifolium repens on growth offspring ramets after...
The seventh part of the series on distributions vascular plants in Czech Republic includes grid maps 104 taxa genera Anthriscus, Callitriche, Cochlearia, Dittrichia, Egeria, Elodea, Elymus, Epilobium, Gentianella, Gnaphalium, Gymnocarpium, Hordeum, Hydrocharis, Limonium, Najas, Phleum, Phragmites, Polypodium, Pseudognaphalium, Rubus, Sedum, Senecio, Setaria, Stratiotes, Trichomanes and Woodsia. These were produced by taxonomic experts based examined herbarium specimens, literature field...
Hieracium s.str. is a complex species-rich group of perennial herbs composed few sexual diploids and numerous apomictic polyploids. The existence reticulation the near-continuity morphological characters across taxa seriously affect species determination, making one best examples 'botanist's nightmare'. Consequently, its relationships have not previously been addressed by molecular methods. Concentrating on supposed major evolutionary units, we used nuclear ribosomal (ETS) chloroplast...
Hieracium subgenus is one of the taxonomically most intricate groups vascular plants, due to polyploidy and a diversity breeeding systems (sexuality vs. apomixis). The aim present study was analyse nuclear genome size in phylogenetic framework assess relationships between ploidy, breeding system selected ecogeographic features. Holoploid monoploid sizes (C- Cx-values) 215 cultivated plants from 89 field populations 42 so-called 'basic' species were determined using propidium iodide flow...
The fourteenth part of the series on distributions vascular plants in Czech Republic includes grid maps 103 taxa genera Achnatherum, Adonis, Consolida, Corallorhiza, Cypripedium, Dianthus, Glaux, Inula, Juncus, Laser, Linum, Mahonia, Malaxis, Mercurialis, Nassella, Ononis, Pseudorchis, Pyracantha, Rosa, Rubus, Sagina, Samolus, Smyrnium, Spiranthes, Stipa and Traunsteinera. These were produced by taxonomic experts based examined herbarium specimens, literature field records. spectrum various...
Background and AimsA detailed knowledge of cytotype distribution can provide important insights into the evolutionary history polyploid systems. This study aims to explore spatial different cytotypes in Pilosella echioides at various scales (from whole distributional range population level) outline possible scenarios for observed geographic pattern.
Plants endemic to areas covered by ice sheets during the last glaciation represent paradigmatic examples of rapid speciation in changing environments, yet very few systems outside harsh arctic zone have been comprehensively investigated so far. The Galium pusillum aggregate (Rubiaceae) is a challenging species complex that exhibits marked differentiation boreal parts Northern Europe. As first step towards understanding its evolutionary history deglaciated regions, this study assesses...
• Background and Aims Genetic variability was estimated for Atriplex tatarica from 25 populations in the Czech Republic. Since its north-western range margin is central Europe, a relationship between marginality low within-population genetic diversity tested accordance with Central–Marginal Model.
Polyploidy is one of the major forces plant evolution and widespread mixed-ploidy species offer an opportunity to evaluate its significance. We therefore selected cosmopolitan Urtica dioica (stinging nettle), examined cytogeography pattern absolute genome size, assessed correlations with bioclimatic ecogeographic data (latitude, longitude, elevation). evaluated variation in ploidy level using extensive dataset 7012 samples from 1317 populations covering most species' distribution area. The...
Processes driving ploidal diversity at the population level are virtually unknown. Their identification should use a combination of large-scale screening ploidy levels in field, pairwise crossing experiments and mathematical modelling linking these two types data. We applied this approach to determine drivers frequencies coexisting cytotypes mixed-ploidy field populations fully sexual plant species Pilosella echioides. examined fecundity seeds from all possible crosses among 2x, 3x 4x...
