Titre : Abundance of Coleanthus subtilis in relation to nutrient concentrations in pond soils – A case study of localities in Poland Type de document : texte imprimé Auteurs : Zygmunt Dajdok, Auteur ; Agnieszka Klink, Auteur ; Ludmila Polechonska, Auteur ; Maegorzata Dambiec, Auteur ; Remigiusz Pielech, Auteur Année de publication : 2017 Article en page(s) : pp. 41-50 Langues : Anglais (eng) Résumé : "Coleanthus subtilis is a rare ephemeral plant species that grows on exposed river banks or pond bottoms. Its natural European localities are considered to be historical ones; however, new localities in man-made habitats have been increasingly reported. Although C. subtilis is protected under international agreements, little is known about the influence of soil chemistry on this species, thus we ask the following questions: i) what is the range of basic soil chemistry parameters for sites colonised by C. subtilis in Poland; ii) how does the soil chemistry influence population density and biomass production of the species; and iii) what is the influence of the soil chemistry on the species composition of plant communities with C. subtilis. We analysed the chemistry of the bottom sediments (pH and concentrations of N, P, K, Ca, Mg, Na, Mn, Fe, Cd, Co, Cr, Cu, Ni and Pb) of 11 fishponds; population density and biomass production were analysed on 47 plots, from which the species composition was determined on 24 samples. The chemistry of the bottom sediments significantly influenced the population density and biomass production of C. subtilis. It was restricted to acidic and neutral substrates and preferred soils rich in N, K, Ca, Mg and Na but poor in P. In such habitats higher biomass production was obtained by C. subtilis, but none of the factors significantly influenced the species composition in its communities."

Titre : Rare wetland grass Coleanthus subtilis in Central and Western Europe - current distribution, habitat types, and threats Type de document : texte imprimé Auteurs : Elke Richert, Auteur ; Roland Achtziger, Auteur ; Zygmunt Dajdok, Auteur ; André Günther, Auteur ; Hermann Heilmeier, Auteur ; Annette Hübner, Auteur ; Henriette John, Auteur ; Katerina Sumberova, Auteur Année de publication : 2016 Article en page(s) : pp. 1-16 Langues : Anglais (eng) Mots-clés : EU Habitats Directive fishponds Isoëto-Nanojuncetea management species protection temporary wetland vegetation Résumé : "The moss grass Coleanthus subtilis (Tratt.) Seidl is a rare, diminutive grass which grows on wet muddy bottoms of drained water bodies displaying a high degree of water level dynamics, such as fishponds or water reservoirs. Due to the temporal character of its habitat, C. subtilis has a very short life cycle of only a few weeks. Therefore, the species and its habitats are legally protected on both national and international levels. This paper focuses on habitats and the conservation of C. subtilis in Central and Western Europe. For the period of 2000–2013, the Czech Republic with more than 200 sites represents the main distribution area of this species in Central and Western Europe. During the same period, C. subtilis was recorded from 45 sites in three regions of Germany (33 Lusatia, 11 Ore Mountains, 1 Mid-Elbe River), 16 sites in France, 13 sites in Poland, and four sites in Austria. Since 2000, the number of records within these seven regions seems to have followed different trends: whereas two regions (Lusatia, Germany and southern Poland) became newly colonized and many populations established, in one region (Ore Mountains, Germany) the number of records diminished. Owing to its specific life cycle, both reproduction success and maintenance of C. subtilis populations are closely linked to the prevailing water level regime, mainly dependent on the management of the water body. Management for the conservation of C. subtilis populations should consider the entire complex of water bodies, as well as individual ponds. For the preservation of the species, at least one pond in each complex should be drained every year and each pond should be drained at least once within 5 years. Depending on local climatic conditions, ponds should be drained for 8–10 weeks during the time period from mid-March to mid-November."
