Public Citation [article]  inPreslia > 84 (2012) . - 257-309 Titre : Inventory of the alien flora of Slovakia Type de document : Électronique Auteurs : Jana Medvecka ; Jan Kliment ; Jana Májeková (1980-) ; Ľuboš Halada ; Marica Zaliberová ; Ema Gojdičová ; VIera Feráková ; Ivan Jarolímek Année de publication : 2012 Article en page(s) : 257-309 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes [CBNPMP-Géographique] Slovaquie Résumé : This is the first complete inventory of alien vascular plant taxa for the Slovak Republic. The presented database contains information on family affiliation, residence status, invasion status, time of introduction, mode of introduction, planting purpose, abundance and distribution within phytogeographic regions, types of invaded habitats and syntaxa, and life forms and geographical origin of the alien taxa. In total, 21.5% of the total flora is made of up of alien taxa, comprised of 282 archaeophytes that make up 6.6% and 634 neophytes 14.9% of the total number of taxa, respectively. The majority of the alien taxa are casuals (57.6%), 39.1% are naturalized and 3.3% invasive. Most of them come from Europe (32.8%) and Asia (32.8%), followed by Africa (12.2%) and North America (10.8%). The database contains members of 98 families of which the Asteraceae, Brassicaceae, Fabaceae, Poaceae, Amaranthaceae and Rosaceae are the most represented. Almost 50% of the alien taxa are therophytes. Hemicryptophytes (26.3%) and phanerophytes (15.6%) are also abundant. More of the alien taxa were introduced deliberately (49.0%) than unintentionally (43.9%), and the majority were introduced as ornamental plants (55.9%). Of the total number of alien taxa, 45.2% are recorded from less than five localities. Most of them prefer human-made habitats; they are found in 137 phytosociological alliances, with those richest in alien taxa categorized as synanthropic vegetation.

Weed vegetation of arable land in Slovakia: diversity and species composition / Jana Májeková in Acta Societatis Botanicorum Poloniae, 88 (4) (2019) 

Public Citation [article]  inActa Societatis Botanicorum Poloniae > 88 (4) (2019) . - 3637 Titre : Weed vegetation of arable land in Slovakia: diversity and species composition Type de document : Imprimé Auteurs : Jana Májeková (1980-) ; Marica Zaliberová ; Iveta Škodová Année de publication : 2019 Article en page(s) : 3637 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Messicole Résumé : Arable fields are among the most widespread habitats in Slovakia, but recently, there have been no studies regarding species composition and structure of weed vegetation in these fields. Therefore, we studied the structure of arable weed vegetation and detected α- and β-diversity. The dataset of 507 phytosociological relevés in different crop types contains 407 plant taxa in 46 plant families. Native plants dominated over aliens, archaeophytes dominated over neophytes, and 14 plants belonged to invasive taxa. The most common species in the dataset were Tripleurospermum perforatum, Cirsium arvense, and Viola arvensis. Weeds were mostly therophytes, b- and a-euhemerobic, competitors, and ruderals, reproducing by seeds and pollinated by insects. The β-diversity of weed vegetation decreased with elevation and temperature and was higher in the Pannonicum than the Carpaticum region. The highest β-diversity was established in fodder+fallow fields, followed by that in cereals and root-crop fields, and the smallest diversity was found in stubble. Beta-diversity increased from spring to summer and slightly decreased again in fall. Detrended correspondence analysis indicated that the major compositional turnover of weed vegetation was related to light, temperature, moisture, and elevation. Weed vegetation constitutes an important habitat in the landscape that provides refuge to many threatened plants, and this vegetation has important functions in the agro-ecosystem food chain.
