The present results were compared with data on L. dortmanna and I. lacustris. It is demonstrated that the community of L. natans differs from the other two communities with respect to habitat conditions despite the fact that they have been reported to occur jointly and alongside in Lobelia lakes. It appears that significant differences between the communities are found not only regarding their waters, but also their substrates. L. natans dominated phytocoenoses are confined to oligotrophic, extremely soft waters, markedly poor in Ca2+, but richer in Na+ and SO4 2- than those of Lobelia and Isoëtes. Luronium natans develops best on acidic, highly hydrated substrates rich in organic matter, NO3 − and total N. The results obtained indicate that L. natans and the phytocoenoses formed by it are characterized by their narrow ecological amplitude in Poland as opposed to those occurring in western Europe, which tolerate a relatively wide range of habitats. The present findings confirm the data from numerous works, which point to the weak competitive ability of the species compared with species typical of eutrophic waters."

Succession is threatening the large population of Lycopodiella inundata (L.) Holub. on anthropogenic site / Marcin Szankowski in Ecological Questions, vol. 22 (2015)  

Public [article]  inEcological Questions > vol. 22 (2015) . - pp. 67-73 Titre : Succession is threatening the large population of Lycopodiella inundata (L.) Holub. on anthropogenic site Type de document : texte imprimé Auteurs : Marcin Szankowski, Auteur ; Monika Bogdanowicz, Auteur ; Anna Sliwinska-Wyrzychowska, Auteur Année de publication : 2015 Article en page(s) : pp. 67-73 Langues : Anglais (eng) Catégories : [ZG] Pologne [Espèces (in biblio)] Lycopodiella inundata (L.) Holub Mots-clés : habitat  succession végétale  espèce végétale protégée Résumé : "Lycopodiella inundata is an endangered, wetland species, able to occur in secondary, anthropogenic habitats. The article presents five-year changes in the occurrence of Lycopodiella inundata on the one of the largest stands in Central Poland. Chosen parameters of population were examined in different stages of vegetation succession. In open thickets the number of fertile stems was near three times higher and amounted above eight hundred fertile stems per square meter. In contrast, in patches with dense herb- and shrub-layer, the low number of fertile stems of L. inundata, have been observed. At anthropogenic sites, where L. inundata occurs, active protection should be made for the inhibition of succession and for the rejuvenation of habitat."
