Effect of environmental conditions on species composition of macrophytes – study from two distinct biogeographical regions of Central Europe
The relationship between macrophytes and environmental conditions of lotic and lentic habitats was studied within two distinct biogeographical regions (Pannonian and Carpathian) represented by two model areas (Borská nížina lowland and Turčianska kotlina basin) in 2011....

| description | The relationship between macrophytes and environmental conditions of lotic and lentic
habitats was studied within two distinct biogeographical regions (Pannonian and
Carpathian) represented by two model areas (Borská nížina lowland and Turčianska kotlina
basin) in 2011. Altogether, 72 taxa of macrophytes were found within both studied
biogeographical regions, while almost a third of them grew only in one from the regions.
Species-environmental variables relationship was studied by Canonical Correspondence
Analysis (forward selection), which revealed that three and seven environmental variables
explaining 10.35% and 24.45% of variance of species data had significant effect on species
composition of macrophytes in the Pannonian and Carpathian region, respectively. Flow
regime and the portion of fine substrate on the bottom are the main drivers of species
composition-environmental condition relationships and explained 3.57% and 6.21% of
variance in the Pannonian and Carpathian region, respectively. However, the highest values
of pure effect on species composition was detected in case of Altitude (Pannonian region;
3.81%) and Connectivity (Carpathian region; 3.19). Based on the variation partitioning,
landscape variables (including geographical variables; Pannonian region; 6.8%) and
hydrological variables (including morphological variables of the bottom; Carpathian
region; 11.3%) explained a bigger portion of the variability of macrophytes in regions
than the other groups of environmental variables. |
