“…2b). In addition, A. lanceolatum was considered to be a characteristic species of this association [40], which resulted in a different syntaxonomical interpretation of the name Butomo-Alismatetum lanceolati (e.g., [8,41]). Several authors also ascribed vegetation with a dominance of Butomus umbellatus and the absence or negligible abundance of A. lanceolatum to this unit (e.g., [37,42]).…”

A new marsh plant community of Eleocharito palustris-Alismatetum lanceolati (Eleocharito palustris-Sagittarion sagittifoliae alliance) in Slovakia

Open and species-poor stands with a dominance of Alisma lanceolatum were recorded in periodically flooded habitats of the southern part of central Slovakia (Ipeľ River catchment area) during the summer of 2013. Phytosociological relevés correspond to the association Eleocharito palustris-Alismatetum lanceolati (alliance Eleocharito palustris-Sagittarion sagittifoliae), which is reported and documented here for the first time from the territory of Slovakia. It inhabits predominantly temporarily flooded depressions on agricultural land -wet arable fields and extensively used pastures. Detrended correspondence analysis showed that the variability in species composition was most significantly influenced by water depth, the presence of arable fields in the contact area and water conductivity. Special attention was paid to a detailed description of the floristic composition, habitat requirements, distribution patterns and nomenclature of the community.

“…Sparganium erectum is a typical helophyte species growing in finer (silt, clay or sand) or organic substrates, in still to slow-flowing, shallow to deep, eutrophic waters; it tolerates water level fluctuation [e.g. 24,29,30]. All these conditions were fulfilled in Stream 2, where this species was among the strongly dominant ones.…”

Seasonal dynamics of macrophyte abundance in two regulated streams

2009

This study analysed seasonal dynamics of macrophyte abundance in two perennial lowland regulated streams (Stream 1 and 2) in the Danube basin (Slovakia). Assessments of macrophyte abundance and environmental characteristics were accomplished 7 times during the vegetation period in 2005 within a 100 m long section. Statistically significant differences in total abundance of macrophytes as well as an abundance of macrophyte groups (hydrophytes, amphiphytes, helophytes) and Potamogeton nodosus were detected among months within the vegetation period. Abundance fluctuations for individual macrophyte groups and species were moderate in Stream 1 and much stronger in Stream 2. Only amphiphytes showed bimodal temporal distribution in Stream 1, but the abundance of this group was low, reflecting more or less random occurrence of species in vegetation period. Multiple linear regression revealed that water depths and air temperature are the most significant environmental variables affecting the seasonal pattern of total as well as dominating group abundance in Stream 1 and 2, respectively. In all cases, abundances are significantly influenced by the abundance of the respective group in the preceding month. Culmination time differed between streams for all macrophyte groups except helophytes. Total abundance culminated 0.57 month later in the Stream 1 compared to Stream 2.

“…In relatively clean and nutrient-poor fishponds prevailing until the middle of the 20th century in climatically suboceanic regions of the Czech Republic and elsewhere in Central Europe, Potamogeton natans was a frequent co-dominant, together with Nymphaea candida Presl, of the communities belonging to the association Potamogetoneto natantis-Nymphaeetum candidae (Hejny and Husak, 1978). This association has mostly changed, as a result of an intensification of fishpond management (higher stocking densities of carp, higher doses of fertilisers, intense liming), all this bringing about an increased phytoplankton production and biomass resulting in less light and less oxygen at the bottom (Pokorny et al, 1990) into the Potamogetonetosum natantis subassociation of the same association, with little or no Nymphaea candida.…”

“…With an even more intense management, leading to a hyper-eutrophication of the fishponds (Matena and Berka, 1987 ;Korinek et al, 1987), this subassociation with dominant or pure Potamogeton natans may be strongly suppressed or eliminated, especially by dense covers of filamentous algae (mainly Cladophora spp.) in understocked ponds, or uprooted by the bottom-feeding carp in overstocked ponds (Hejny and Husak 1978). Potamogeton natans, however, appears to tolerate a wide range of nutrient supply up to a moderate level of eutrophy (Hutchinson, 1975), but sediments rich in nutrients and anaerobic organic matter, which accumulate in intensely managed fishponds, seem to be detrimental to this plant species (Hejny and Husak 1978).…”
