Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Sporobolus cryptandrus A.Gray, 1848 Résumé : For the effective control of an invasive species, gathering as much information as possible on its ecology, establishment and persistence in the subjected communities is of utmost importance. We aimed to review the current distribution and characteristics of Sporobolus cryptandrus (sand dropseed), an invasive C4 grass species of North American origin recently discovered in Hungary. We aimed to provide information on (i) its current distribution paying special attention to its invasion in Eurasia; (ii) the characteristics of the invaded habitats in Central Europe; (iii) seed bank formation and germination characteristics, crucial factors in early establishment; and (iv) the effects of its increasing cover on vegetation composition. Finally, we aimed to (v) point out further research directions that could enable us to understand the invasion success of this potential invasive species. Field surveys uncovered large stands of the species in Central and Eastern Hungary with most of the locations in the former, especially the Kiskunság region. The species invaded disturbed stands of dry and open sand grasslands, closed dune slack grasslands and it also penetrates into natural open sand grasslands from neighbouring disturbed habitats. Increasing cover of Sporobolus cryptandrus caused a decline in species richness and abundance of subordinate species both in the vegetation and seed banks, but a low density of Sporobolus cryptandrus can even have a weak positive effect on these characteristics. Viable seeds of Sporobolus were detected from all soil layers (2.5 cm layers measured from the surface to 10 cm in depth), which indicates that the species is able to form a persistent seed bank (1,114 to 3,077 seeds/m2 with increasing scores towards higher abundance of the species in vegetation). Germination of Sporobolus cryptandrus was negatively affected by both litter cover and 1 cm deep soil burial. To sum up, Sporobolus cryptandrus can be considered as a transformer invasive species, whose spread forms a high risk for dry sand and steppe grasslands in Eurasia. We can conclude that for the effective suppression of the species it is necessary: (i) to clarify the origin of the detected populations; (ii) to assess its competitive ability including its potential allelopathic effects; (iii) to assess its seed bank formation potential in habitats with different abiotic conditions; and (iv) to assess the possibility of its suppression by natural enemies and management techniques such as mowing or livestock grazing.

[CBNPMP-Thématique] TaxonomieMots-clés : Sporobolus cryptandrus A.Gray, 1848 Résumé : The paper presents new records for 20 vascular plant species from 13 Eurasian countries. Four taxa (Calamagrostis sichuanensis, Klasea dissecta, Ptilagrostis milleri and Stipa klimesii) are reported from China, four (Aconogonon valerii, Carex siderosticta, Poa tanfiljewii and Potamogeton × subobtusus) from Russia, three (Amorpha fruticosa, Carduus acanthoides and Plantago minuta) from Tajikistan, two (Achillea sergievskiana and Delphinium barlykense) from Kazakhstan, one (Calamagrostis effusiflora) from Bhutan and India, one (Campanula wolgensis) from Mongolia, one (Orobanche coerulescens) from Georgia, two (Dysphania geoffreyi and Ptilagrostis milleri) from Nepal, one (Stipa × alaica) from Afghanistan, one (Stipa × manrakica) from Kyrgyzstan, one (Ranunculus × gluckii) from Poland and one (Sporobolus cryptandrus) from Italy. Four of the taxa presented (Amorpha fruticosa, Carduus acanthoides, Carex siderosticta and Sporolobus cryptandrus) are regarded as alien to the studied areas, whereas the remaining 16 are native elements to the flora of the countries. For each species synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition and differentiation of the species from the most similar taxa occurring in a given country, as well as a list of recorded localities (often far from the previously known areas) are presented. Based on the spikelet morphology, we have proposed in Ptilagrostis a new section Barkworthia M. Nobis, A. Nobis & A. Nowak, which comprises two species Ptilagrostis yadongensis and Ptilagrostris milleri, with distinctly unequal glumes, lemmas and paleas.
