This transitional area between the forest-steppe biome of the Pannonian biogeographical region and the temperate forest biome hosts scattered patches of natural steppe embedded in forests, especially in rugged landscapes. The unique geographical position is reflected in the plant assemblages, which are composed of species of different origins, mainly central-European, continental, Mediterranean and sub-Mediterranean. We sampled sites with well-preserved forest-steppe vegetation on different substrates across this region. At each site, we sampled the vegetation in three habitats: steppe, forest and ecotone. We then attempted to disentangle the influence of geographical location, climate and substrate on the species composition of forest-steppe landscapes and the percentage of the species with a particular type of distribution. We found that substrate is the main factor determining species sorting. Substrate is also largely responsible for the percentage of species with particular types of distribution. While continental species are most frequent on loess, Mediterranean species are mainly found on andesite. Sub-Mediterranean species are most frequent on dolomite and rare on loess. The distributions of these species can be explained by the environmental conditions in the core of their native ranges. The complexity of the distribution patterns of species in the north-western Pannonian forest-steppe shown in this study should be considered in the discussion of the environmental history of the region and conservation planning.","PeriodicalId":20501,"journal":{"name":"Preslia","volume":"42 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78564766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New data accumulated in the last decade are incorporated and the listing and status of some taxa are reassessed based on improved knowledge. Alien flora of the Czech Republic consists of 1454 taxa listed with information on their taxonomic position, life history, geographic origin (or mode of origin, distinguishing anecophyte and hybrid), invasive status (casual; naturalized but not invasive; invasive), residence time status (archaeophyte vs neophyte), mode of introduction into the country (accidental, deliberate), and date of the first record. Additional information on species performance that was not part of the previous catalogue, i.e. on the width of species’ habitat niches, their dominance in invaded communities, and impact, is provided. The Czech alien flora consists of 350 (24.1%) archaeophytes and 1104 (75.9%) neophytes. The increase in the total number of taxa compared to the previous catalogue (1378) is due to addition of 151 taxa and removal of 75 (39 archaeophytes and 36 neophytes), important part of the latter being the reclassification of 41 taxa as native, mostly based on archaeobotanical evidence. The additions represent taxa newly recorded since 2002 and reported in the national literature; taxa resulting from investigation of sources omitted while preparing the previous catalogue; redetermination of previously reported taxa; reassessment of some taxa traditionally considered native for which the evidence suggests the opposite; and inclusion of intraspecific taxa previously not recognized in the flora. There are 44 taxa on the list that are reported in the present study for the first time as aliens introduced to the Czech Republic or escaped from cultivation.","PeriodicalId":20501,"journal":{"name":"Preslia","volume":"38 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78522355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we study Solidago ×niederederi, which originated and became established in Europe as a result of a cross between the alien S. canadensis and native S. virgaurea. The recent increase in the number of records of S. ×niederederi in Europe has highlighted the need to monitor its occurrence, spread and behaviour. In the present study, we tested the effectiveness of flow cytometry for detecting hybrid plants of S. ×niederederi. Sequences of the ITS region of nrDNA and the rpS15-ycf1 spacer of cpDNA were used to confirm the hybrid origin of analysed plants and to identify the maternal species. Our study included 60 single-species populations of S. canadensis, S. gigantea and S. virgaurea, and 16 mixed populations with the presence of hybrid S. ×niederederi sampled from six countries in central Europe and adjacent areas. All individuals of S. canadensis, S. ×niederederi and S. virgaurea investigated were diploid (2n~2x~18) but differed in their relative DNA content values. The DNA content of S. ×niederederi was intermediate between S. canadensis and S. virgaurea with no overlaps, with the differences between the species being statistically significant. Therefore, we conclude that flow cytometry is a reliable and efficient method for detailed screening for hybrids within mixed Solidago populations and for identifying non-flowering or morphologically ambiguous Solidago plants. Since both parental species varied only negligibly in their DNA content, it may also be applicable across a broader geographic scale. Genetic, flow cytometric and distributional data suggest that the hybrids are to a large extent early generation (likely F1) hybrids as very few cases of supposed introgressants were also inferred. The results from chloroplast rpS15-ycf1 spacer showed that hybridization has occurred in both directions.","PeriodicalId":20501,"journal":{"name":"Preslia","volume":"52 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73622446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
