“…The present dataset provides the most comprehensive information on genomic parameters ever provided for a flora of a particular country. These data are now incorporated into the Database of the Czech Flora and Vegetation (Pladias; www.pladias.cz, Wild et al 2019) and will be updated when new measurements become available. This dataset will enable robust tests of the effect of individual genomic parameters on species anatomy, physiology, morphology and ecology (e.g.…”

“…Because of its important ecological consequences, information about genome size and/or ploidy level is included in modern biological floras and trait databases such as the Ecological Flora of the British Isles (Fitter & Peat 1994; http://www.ecoflora.co.uk), the Database on Biological and Ecological Traits of the Flora of Germany (BiolFlor; Klotz et al 2002, www.biolflor.de) and the Global Plant Trait Database (TRY; Kattge et al 2011, http://www.try-db.org). Information about genome size will also be included in the Database of the Czech Flora and Vegetation (Pladias; www.pladias.cz, Wild et al 2019). However, there is no genome size data for many widespread species, and the data reported in the literature are sometimes difficult to use for a variety of reasons (see below).…”

“…The goal was to prepare comprehensive and cross-comparable data on genome sizes, genomic GC contents and associated metrics (ploidy level and monoploid genome size) of Czech vascular plants. This work will (i) serve as the base for the genomic and karyological traits section of the Database of the Czech Flora and Vegetation (Pladias; www.pladias.cz, Wild et al 2019) and will (ii) enable the testing of hypotheses about the evolution and biological relevance of these parameters.…”

Genome sizes and genomic guanine+cytosine (GC) contents of the Czech vascular flora with new estimates for 1700 species.-Preslia 91: 117-142. The content of DNA in the somatic, unreplicated cell nuclei (genome size) and DNA base composition (GC content) are the basic genomic parameters that can be measured by flow cytometry. Genome size, or ploidy level, can affect many plant properties and are therefore included as important features in modern biological floras and plant trait databases. However, genomic data are still largely measured mainly for taxonomic and biosystematic purposes, and despite the popularity of flow cytometry in the Czech Republic, this information is still missing for many of the vascular plants in the Czech flora. The biological significance of the GC content is less clear compared to the genome size, which, along with the greater difficulty in measuring it, results in the absence of such information for the vast majority of species. Here, we measure these two genomic parameters for 1908 samples of 1700 species in the Czech vascular flora. Here for the first time are reported the genome sizes of more than 1000 species and GC contents of more than 1500 species, which more than doubles the amount of information on the GC content of vascular plants. Together with the published data obtained in our laboratory using the same methods and flow cytometers, this information is now available for 1910 species that occur in the Czech Republic (~83% of this country's permanent flora, excluding apomicts). They are summarized in a table, accompanied by information about assumed chromosome number, ploidy level and an estimate of the monoploid genome size. We further provide a descriptive analysis of this dataset, list extreme values and comment on some cytogeographically interesting findings. This dataset is the largest and most comprehensive set of genomic data covering almost the entire flora of a country. It will serve as the basis of the karyological traits section of the Czech plant trait database Pladias (www.pladias.cz) and for testing of hypotheses about the evolution and biological relevance of these genomic parameters.

“…Integration of all available records on the distribution of vascular plants in the Czech Republic into a single central database and initiation of mapping their distributions were two of the aims of the PLADIAS project funded by the Czech Science Foundation in 2014-2018. The plant occurrence module within a new Pladias database (www.pladias.cz) was launched in 2014 and now contains more than 13 million records of almost 5 thousand taxa of various ranks (Wild et al 2019). This database and an associated web-based mapping interface serve as a basic platform for mapping plant distributions within this country.…”

Closely related species differ in their traits, but competition induces high intra‐specific variability

Theories explaining community assembly assume that biotic and abiotic filters sort species into communities based on the values of their traits and are thus based on between‐species trait variability (BTV). Nevertheless, these filters act on individuals rather than on species. Consequently, the selection is also influenced by intraspecific trait variability (ITV) and its drivers. These drivers may be abiotic (e.g., water availability) or biotic (e.g., competition). Although closely related species should have similar traits, many of them coexist. We investigated the relative magnitudes of BTV and ITV in coexisting closely related species and how their individual traits differ under different drivers of ITV. We manipulated conditions in a greenhouse pot experiment with four common Carex species, where individuals of each species originated from four source localities. Individuals were grown in factorial combinations of two moisture levels, with and without a competitor (grass species Holcus lanatus, a frequent competitor). We analyzed the variability of six morphological traits on individuals in the greenhouse and three morphological traits in the source localities. Species identity was the main determinant of differences in most traits. Competition exerted a greater effect than water availability. For leaf dry matter content (LDMC) and vegetative height, competition's effect even exceeded the variability among species. On the contrary, for specific leaf area (SLA) and clonal spread, the interspecific differences exceeded ITV induced by experimental treatments. SLA measured in the greenhouse closely correlated with values measured in field populations, while LDMC did not. The variability caused by source locality of ramets in the greenhouse was small, although sometimes significant. Closely related species differ in their traits, but for some traits, ITV can exceed BTV. We can expect that ITV can modify the processes of community assembly, particularly among coexisting closely related species.
