“…Because planktonic algae and cyanobacteria may quickly respond to changing environmental factors (Brettum & Andersen, 2005;Laplace-Treyture & Feret, 2016;Napiórkowska-Krzebietke, Stawecki, Pyka, Zdanowski, & Zebek, 2016;Padisák et al, 2006;Reynolds et al, 2002), phytoplankton is an important element of the ecological monitoring of aquatic ecosystems and is included in the EU Water Framework Directive (WFD 2000/60/EC;EC Parliament Council, 2000). The similarity in composition of phytoplankton assemblages in similar lakes and at similar times is easier to explain than the differences in assemblage structure in lakes of different types, hydromorphology, or catchments (Reynolds, 2006).…”

Impact of lake‐catchment processes on phytoplankton community structure in temperate shallow lakes

Research on lake-catchment and biological processes is still innovative. Few reports on this topic exist in the scientific literature. This paper presents species richness, diversity, biomass composition of phytoplankton, and occurrence of cyanobacterial blooms in relation to complex lake-catchment processes in four shallow lakes. The results revealed that phytoplankton species richness increased with increasing lake trophic state, whereas the opposite relationship was observed for phytoplankton biodiversity. In less eutrophic and deeper lakes, the majority of dominant taxa were representatives of mixed, meso to eutrophic small-and medium-sized lakes. In highly eutrophic lakes, the dominant taxa were common representatives of shallow, very rich in nutrients, turbid, mix layers, and eu-hypertrophic environments. Redundancy analysis showed that lake depth, flushing time, and conductivity were the most significant factors for phytoplankton development and composition. The hypertrophic, polimictic, and flow-through Lake Syczyńskie was the most dynamic ecosystem among the lakes. Water mixing and high concentrations of P-PO 4 were beneficial for heavy blooms of the cyanobacterium Planktothrix agardhii observed in Lake Syczyńskie despite the high rate of water exchange. Contrary to the findings of some previous studies, P. agardhii seems to be resistant to flushing at very high loads and concentrations of nutrients (mostly of P-PO 4 and N-NO 3 ). Phytoplankton assemblages reflected the lakes' habitats, trophic status, and lake-catchment processes and revealed complex factors that influenced the lakes' functioning. The use of phytoplankton as an indicator of lake-catchment processes may help understand ecosystem dynamics, essential for the proper selection of management practices protecting aquatic systems against eutrophication.

“…Planktonic algae are the main oxygen producers and components of food chains, particularly in eutrophic ecosystems. Phytoplankton development and structures closely reflect the ecological and trophic status of freshwaters . Thus, phytoplankton is also an important element of ecological monitoring and is included in the EU Water Framework Directive (WFD) .…”

Although water quality has been the main concern of ecologists over the last decades, a deterioration of both the quality and quantity of water has been observed worldwide. Understanding the dominant processes shaping eutrophication processes is crucial to sustainable water management in lake catchments. The aim of the study was to determine the importance of elements of lake‐catchment system structures in the processes of shaping lake water quality. The values of loads delivered to the lake basins from their catchments as well as nutrient output were calculated on the basis of stream discharge and nutrient concentration. A range of hydro‐chemical influences of each stream was presented by means of a range of a radius. A model of nutrient transport (prepared in GIS software) was used in the catchment of a lake without tributaries. Additionally, phytoplankton abundance and water quality indices were calculated. The results showed a clear pattern for the following lakes, Syczyńskie > Pniówno > Chuteckie > Tarnowskie, in terms of nutrient load as well as water quality. The hydro‐chemical influence of lake tributaries was determined by runoff processes, which reflected catchment geology, relief, and flushing time. The Q index showed a good ecological status for lakes Chuteckie and Tarnowskie, moderate for Lake Pniówno, and poor for Lake Syczyńskie.
