Nymphaeetum candidae Miljan 1933 in Poland
2011
This paper presents the distribution, floristic composition and ecological requirements of the water plant community <em>Nymphaeetum candidae</em> Miljan 1933, belonging to the <em>Potametea</em> class. Until present this community has been reported only from north-eastern Poland. During present studies it was stated also in the south-western part of the country. <em>Nymphaeetum candidae</em> is considered to be a rare and endangered plant community in several countries of Central Europe.
Nymphaeetum albae Vollmar 1947 em. Oberd. in Oberd. et al. 1967, a plant association new to Poland
2011
The paper presents a water plant community new to Poland - <em>Nymphaeetum albae</em> Vollmar 1947 em. Oberd. in Oberd. et al. 1967, belonging to the i class. It was discovered in fishponds in Pokój near Namysłów, Lasowice Małe near Kluczbork and small ponds in Staniszcze Małe near Opole in Silesia (SW Poland). Floristic composition and ecological requirements of this association are presented in the paper. <em>Nymphaeetum albae</em> is considered to be a rare and endangered plant community in Europe.
Potametum alpini Podbielkowski 1967 w starorzeczach południowo-zachodniej Polski
2018
The paper presents the distribution and habitat conditions of Potametum alpini communities (class Potametea) in oxbow lakes of south-western Poland. A study done in 2000–2015 identified 11 localities of this community in oxbow lakes. The threats to Potametum alpini in south-western Poland include changes in the levels and physicochemistry of the water.
Zespół rdestnicy wydłużonej Potametum praelongi Sauer 1937 w rezerwacie Smolnik na Śląsku Opolskim
2018
Na terenie rezerwatu przyrody Smolnik na Śląsku Opolskim fitocenozy zespołu rdestnicy wydłużonej Potametum praelongi zostały stwierdzone podczas badań geobotanicznych w 2015 r. – współrzędne geograficzne 50°83'97,62'' N, 18°24'59,79'' E. Dotychczas zespół ten nie był notowany na obszarze tego rezerwatu. W Polsce należy do bardzo rzadko notowanych zbiorowisk. W rezerwacie Smolnik płaty tego zespołu wykształciły się w wodzie o głębokości 150 – 200 cm, o pH 7,4. W większości z nich ma budowę dwuwarstwową, rzadziej jednowarstwową. Zespół ten zajmuje powierzchnie, sięgające maksymalnie 200 – 300 m2. Notowano w nich od 5 do 7, średnio 6 gatunków. Łącznie w jego fitocenozach zanotowano 8 gatunków …
Fitocenozy zespołu rdestnicy wydłużonej Potametum praelongi w starorzeczach południowo-zachodniej Polski
2018
Zespół rdestnicy wydłużonej Potametum praelongi Sauer 1937 należy do jednego z najrzadziej spotykanych zbiorowisk roślin wodnych w Polsce. Celem pracy jest przedstawienie aktualnego rozmieszczenia i charakterystyki Potametum praelongi w starorzeczach na terenie Dolnego Śląska i Śląska Opolskiego. Badania wykonano w latach 2000–2015. Stwierdzono pięć dotychczas nieznanych stanowisk tego zbiorowiska w starorzeczach Odry.
The role of Characeae in the communities of the vegetation class Potametea
2018
The stonewort vegetation is commonly classified into the phytosociological class Charetea fragilis F. Fukarek ex Krausch 1964; however, the Characeae are not exclusively found in vegetation stands ascribed to this class but also in other habitat types. In our preliminary investigations, we draw the attention to the relationship between the classes Charetea fragilis and Potametea pectinati Klika in Klika & Novák 1941 in some Sicilian biotopes. In some cases, the Charetea vegetation is ecologically and spatially distinct, although close, from that referable to the Potametea. In some other cases, one or more species of Characeae are structurally intrinsic to the vegetation of Potametea: on…
Hydrophytic vegetation aspects in the Nebrodi Mountains (Sicily).
2011
A study of the hydrophyte communities of some small ponds in the beech-wood belt of the higher Nebrodi Mts is presented. A new association of shallow stagnant water bodies, the Utriculario-Potametum natantis, is described. Its biological structure, biogeographical characteristics, syntaxonomic position, phytosociological relationships and dynamic links are discussed.
Veronico beccabungae-callitrichetum stagnalis (Oberd. 1957) Müller 1962, a plant association new to Poland - Quality of habitat
2011
The paper presents a community of water plants that is new to Poland, <em>Veronico beccabungae-Callitrichetum</em> stagnalis (Oberd. 1957) Müller 1962. This community belongs to the class <em>Potametea</em>. It was discovered in the village of Odrowąż near the town of Krapkowice in Silesia (SW Poland). <em>Veronico beccabungae-Callitrichetum stagnalis</em> in Poland occurs within an irregularly shaped shallow underwater spring, located in the distal part of the Oder River’s flood terrace. This plant community covered 0.2 ha in 2008. <em>Callitriche stagnalis</em> predominated in this community. Species such as <em>Callitriche hamulata<…
