[Espèces (in biblio)] Corynephorus canescens (L.) P.Beauv.Mots-clés : succession végétale Résumé : "The succession of vegetation on acidic sandy fields after abandonment was studied and obtained results were compared with similar data from eastern part of Europe. the vegetation changes head towards oligotrophic Corynephorus-grasslands, because nutrients from the upper layer of soils are gradually washed out. Dry, occasionally blowing sand enables the growth of psammophytes very well. The paper compares the succession models on abandoned sandy fields, and semi-natural acidic sandy dunes in western part of Slovakia, southern Moravia, Hungary and Croatia. In spite of amazing similarities, some differences are displayed using spectra of life forms and presentation of weeds."

Titre : Distribution and Ecology of Corynephorus canescens (L.) p. Beauv. (Poaceae) in the left bank Forest-Steppe of Ukraine Auteurs : Denis A.

Mots-clés : découverte floristique nouvelle espèce végétation psammophile zone forêt-steppe Résumé : "The article summarizes data about the distribution of Corynephoruscanescens(L.) P.Beauv.in the Left Bank Forest-Steppe of Ukraine. This species which is native for Europe and North Africa was firstly found on the research territory. Currently nine localities of this vascular plant species are known within Kyiv (seven locations) and Poltava (two locations) administrative regions. Based on the analysis of geobotanical relevés made by authors on psammophytic vegetation plots with the participation of Corynephoruscanescensit was found that studied sand areas within Kyiv region belong to the associationCorniculario aculeatae-Corynephoretum canescentis Steffen1931 from the classKoelerioglaucae-CorynephoreteacanescentisKlikainKlika& Novak1941 (allianceCorynephorioncanescentisKlika1931, orderCorynephoretaliacanescentisKlika1934); they have clear two-layered structure with the substantive complicity of moss and lichen species. On the other hand, similarpsammophytic communities within Poltava region have the simplified one-layered composition with the tenuous herb cover and the absence of moss and lichen layers; they are treated by authors as a separate community –comm. CorynephoruscanescenswithintheclassKoelerioglaucae-Corynephoreteacanescentis. Based on these ecological data,Corynephoruscanescensis considered as a species with dissimilar status in different parts of the research territory. Found localities of this species within Poltava region are to be treated as alien and associated with human activity,but in the southern part of Kyiv region,the autochthonous (or atleast simultaneously mixed indigenous and antropogenic) dispersal of its diaspors by anemochory is quite reliable. The phytosociological tables of geobotanical relevés made by authors in Kyiv and Poltava administrative regions in 2017–2020 are presented. The status of Corynephoruscanescens on other territories near the eastern border of the area of its distribution is discussed.Keywords: floristic finding, new species, psammophytic vegetation, the Forest-Steppezone."

[Thèmes] VégétationMots-clés : suivi à long-terme restauration Spergulo-Corynephoretum Résumé : "Open sand vegetation on inland dunes is among the most endangered vegetation types of Central Europe. Weakly competitive pioneer species with subatlantic distribution, such as the grey-hair grass (Corynephorus canescens), are the first colonizers. In two restoration areas in the border zone of meanders of the Hase river (Emsland, NW Germany), in part formerly under intensive agricultural management, Corynephorus pioneer vegetation (Spergulo vernalis-Corynephoretum canescentis) has been established by restoration measures. Newly created dune areas (“neodunes”) with low soil-nutrient conditions were created, inoculated and extensively grazed mainly by cattle (seldom horses). Inoculation was implemented by the transfer of mown and raked plant material from a target area (nature reserve area nearby). Ten years after the restoration measures C. canescens is still growing on all inoculated sites of the new dune systems and on old dune fragments, but the plant communities differ. A new settlement of C. canescens was observed on one open sandy site near the river. Differences in coverage of open sand, humus content of substrate as well as number and composition of competing plant species influence the vitality of Corynephorus individuals and the size of their populations. The tufts vary in frequency, size, vitality and number of dispersal units. With regard to these parameters the inoculated newly created dune areas differ significantly from the old dune fragment and the site with new spontaneous settling. The size of the tufts is correlated with the number of inflorescences and dispersal units. Tuft size corresponds to current growing conditions. Long-term persistence depends on a complex interacting network of several factors. High individual phytomass guarantees successful dispersal by influencing the numbers of inflorescences and diaspores. Long-term persistence of C. canescens populations in the complex of the new dune systems cannot be ensured under the current conditions (e. g. competition with other plant species, relatively high humus accumulation, lack of stronger dynamics). A higher grazing impact should enhance redynamization."

Titre : Relationship Between Compositions of Grey Hair-Grass (Corynephorus Canescens (L.) P. Beauv.) Tissues and Soil Properties During Primary Vegetation Succession Auteurs : Oimahmad Rahmonov, Auteur ; Jacek Rozkowski, Auteur ; Artur Szymczyk, Auteur Article en page(s) : 012009 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Corynephorus canescens (L.)

[Thèmes] Pédologie (sol)Mots-clés : pédogenèse arénosol Résumé : "This study focuses on the concentration of trace-, microelement- and organic components in initial horizons of sandy soil (Arenosole) and of the tissues of Corynephorus canescens, a pioneer species typical of unstable environments that initiates pedogenic processes by enriching poor quartz sand in organic- and mineral matter from its own tissues. Soil samples were taken from a root-zone humus horizon (A) averaging ∼15 cm in thickness and from parent rock. Concentrations of Ca, Mg, K, Na, Fe, Si, Al, Zn, Mn, Co, Cd, Pb, Sr, Mo, C, N and P in plant material and soil were analyzed. High concentrations of Si (6368-16.3 mg•kg-1), K (2310-165.2), Ca (302-24.6 mg•kg-1), Fe (2196-316.3) are found in the above-ground part of the plant whereas Si (9150-20), Fe (5948- 43), K 3752-3.21) and Al (2370-52.6 mg•kg-1) dominate in the roots. Soil organic carbon (OC) contents in the humus horizon and in parent rock are 0.276-0.041 and 0.206-0.041%, respectively. The concentration of nitrogen in the humus horizon shows a high (0.92) correlation with OC. The soil shows both acid (4.2-0.51 in KCl) and low-acid (5.1-0.23 in H2O) characteristics. Heavy-metal contents differ significantly among the study sites. Organic compounds of Corynephorus canescens and of soil organic matter (SOM) were investigated by pyrolysis-GC/MS (Py-GC/MS). In the organic content of the grey hair-grass tissues, typical compounds such as normal chain aliphatics (29%), and furane- and pyrane derivatives (12%), dominate. Nitrogen-containing substances such as amines, nitro compounds, heterocycles and amines are also important (27%). The main ecopedological role of C. canescens involves the fixing of loose sand thanks to its well-developed root system. The xeromorphic structure of stems and leaves allows it to function in such extreme open areas of unstable ground and high insolation. The initial stage of the formation of a humus horizon involving Corynephores canescens is documented."

[Thèmes] VégétationMots-clés : phytosociologie communauté végétale Résumé : "In Italy, Corynephorus communities are distributed along the medium course of the Ticino river and Sesia river and the internal sand dunes of Lomellina (through the Vercelli, Novara and Pavia provinces); these stations represent the southern limit of European distribution of this habitat. A phytosociological study was carried out to gain better knowledge of their composition; of their affinity or diversity against the central European communities; of their distribution and of the main threats to their conservation. Original and literature relevés (114) were elaborated producing a cluster analysis; correspondence analysis (CA), principal component analysis and Kruskal–Wallis test were carried on to characterize the clusters of relevés taking into consideration biological forms, chorological groups, Ellenberg indicator values and floristic groups. Italian Corynephorus communities can be attributed to the following syntaxa: Spergulo vernalis-Corynephoretum canescentis, Spergulo vernalis-Corynephoretum canescentis cladonietosum, Spergulo vernalis-Corynephoretum canescentis silenetosum nutantis and Spergulo vernalis-Corynephoretum canescentis artemisietosum campestris. Italian Corynephorus communities are included in the Habitat 2330 of the EU Habitat Directive. They are threatened by different factors (such as restricted areas of occurrence, alien plant invasion and natural dynamics) and they need to be managed if we want to conserve them."
