Sažetak
Biodiversity protection and sustainable management of freshwater karstic ecosystems require a set of good governmental policies and measures based on competent decision-making, and establishment of relevant practices founded on the best available technologies and high quality knowledge. Traditional monitoring systems have several substantial drawbacks, like tediousness and expensiveness, difficult automation of processes and doubtful sensitivity, as well as inability to provide prompt, immediate information about the ecological status of a lake. To overcome these deficiencies new innovative methods and alternative rapid monitoring tools, such as environmental DNA metabarcoding (eDNA), pigment analyses and automatic monitoring systems for high-frequency measuring and real-time management based on development of the Information and Communications Technology (ICT), were developed in recent years. The current study, carried out during August 2018 on Lake Visovac (Croatia), provides results of taxonomic analyses, phytoplankton biomass, in situ measuring of physical and chemical parameters, chlorophyll a concentration and eDNA analyses, all in correlation with data collected from the in situ water sensor installed on the buoy. In contrast to single point measurements of the water sensor, phytoplankton composition and biomass were investigated in vertical profiles on 10 sampling points along the limnetic and littoral zone of the Lake. A strong separation between limnetic and littoral zone samples was recorded, together with statistically significant differences in the ecological status based on phytoplankton as biological quality element (BQE). Grouping of buoy sensor data with samples from the littoral zone revealed that buoy data were not comparable with data from the monitoring site in the limnetic zone. Moreover, analyses of chlorophyll a and eukaryotic eDNA have shown comparable results with traditionally obtained ecological status based on BQE phytoplankton and can be successfully used in biomonitoring.
