Flora of Algae and Cyanobacteria of Continental Waters of Israel in the XXI Century: Taxonomy, Autecology and Water Quality Indicators

The article presents a list of algal species and cyanobacteria found in the continental waters of Israel in 1898-2022. Research progressed in 2000-2022 by increasing the list from 1261 to 1628 species belonging to fourteen phyla. Taxonomic analysis shows that diatoms, cyanobacteria, and green algae predominated. The first-time data has been synthesized to identify the indicator properties of Israel's aquatic flora carried out on algae and cyanobacteria, which can be used to monitor water quality. The species' ecological preferences are given for ten environmental variables: substrate preference, temperature, oxygen saturation with water mobility, water pH preferences, water salinity, organic pollution according to Watanabe and Sladecek with species-specific index of saprobity S, trophic state, and type of nutrition (autotrophic or heterotrophic). This list of species with indicator values for each species is used to characterize the water properties in Israel. In addition, it can be applied to assess the state of aquatic ecosystems and monitor water quality based on bioindication methods.

Automated summary

The article provides a list of algal species and cyanobacteria found in the continental waters of Israel from 1898 to 2022. The research shows an increase in species diversity, with diatoms, cyanobacteria, and green algae being dominant. The data synthesis identifies indicator properties that can be used for water quality monitoring and assessment of aquatic ecosystems.
