Environmental Characteristics and Anthropogenic Impact Jointly Modify Aquatic Macrophyte Species Diversity
2018
Species richness and spatial variation in community composition (i.e. beta diversity) are key measures of biodiversity. They are largely determined by natural factors, but also increasingly affected by anthropogenic factors. Thus, there is a need for a clear understanding of the human impact on species richness and beta diversity, the underlying mechanisms, and whether human-induced changes can override natural patterns. Here, we dissect the patterns of species richness, community composition and beta diversity in relation to different environmental factors as well as human impact in one framework: aquatic macrophytes in 66 boreal lakes in Eastern Finland. The lakes had been classified as h…
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.
