Zbiorowiska roślinne z klasy Utricularietea intermedio-minoris w stawach hodowlanych południowo-zachodniej Polski
2017
Zbiorowiska z klasy Utricularietea intermedio-minoris Den Hartog et Segal 1964 em. Pietsch 1965 należą do wyspecjalizowanych pod względem ekologicznym fitocenoz, występujących w wodach oligotroficznych, mezotroficznych oraz dystroficznych na podłożu torfowym. W Polsce należą do grupy zbiorowisk bardzo słabo zbadanych. Celem pracy było przedstawienie aktualnego rozmieszczenia i charakterystyki fitosocjologicznej zespołów z klasy Utricularietea intermedio-minoris, których fitocenozy stwierdzono w latach 2000–2015 w południowo-zachodniej Polsce na terenie stawów hodowlanych województw: dolnośląskiego i opolskiego. W trakcie przeprowadzonych badań zostały wykazane dwa zespoły z tej klasy: zespó…
Wetland Restoration with Hydrophytes: A Review
2021
Restoration cases with hydrophytes (those which develop all their vital functions inside the water or very close to the water surface, e.g., flowering) are less abundant compared to those using emergent plants. Here, I synthesize the latest knowledge in wetland restoration based on revegetation with hydrophytes and stress common challenges and potential solutions. The review mainly focusses on natural wetlands but also includes information about naturalized constructed wetlands, which nowadays are being used not only to improve water quality but also to increase biodiversity. Available publications, peer-reviewed and any public domain, from the last 20 years, were reviewed. Several countrie…
The Eurasian spoonbill Platalea leucorodia in Sicily between 1972 and 2018, distribution and ecology
2020
The observations of the Eurasian spoonbill made in Sicily between 1972 and 2018 were collected and analyzed. The presences, initially scarce and referred to a few sites, have consolidated over time, and gradually have affected an increasing number of sites. The observations were concentrated in the coastal salt pans and exsalt pans systems, secondarily in the mouths and in inland waters, below 100 m a.s.l.. The greatest number of Eurasian spoonbill was found in the migration period, both post and pre-reproductive; in the summer the lowest values. The average number of birds per flock, compared to subsequent years, from November to January did not vary significantly, while it was variable in…
