“…However, of note is an increase in the diversity of the benthic flora on the rocky substrates of the open shores of Lake Baikal compared to that at the end of the past century. Not only the Spirogyra algae but also Oedogonium have become frequent in the benthic algal flora [ 51 ].…”

“…The latter species is a mass of algae that develops at the bottom of the bay at depths of >3 m. Overgrowth of the bottom with the filamentous Spirogyra algae (the algal thallus is represented by unbranched filaments) has effects on communities in the water column. Its cells have hydraulic characteristics similar to planktonic algae and can enhance autotrophic productivity in the surface water of the Baikal ecosystem [ 51 ]. In benthic communities of Listvennichny Bay, filamentous algae inhabiting a wide range of aquatic environments replaced endemic species dominant in the biomass.…”

Recent studies have revealed how the freshwater biota of Lake Baikal responds to climate change and anthropogenic impacts. We studied phyto- and zooplankton, as well as phyto- and zoobenthos, in the open coastal waters of the southern basin of the lake and of Listvennichny Bay. A total of 180 aquatic organism taxa were recorded. The response of the Baikal ecosystem to climate change can be traced by changes in the species composition of planktonic communities of the lake’s open coasts in summer. The key species were thermophilic the Anabaena lemmermannii P. Richt. (Fij = +0.7) blue-green algae, the Asplanchna priodonta Gosse (Fij = +0.6) rotifers in 2016, the Rhodomonas pusilla (Bachm.) Javorn. (Fij = +0.5) cold-loving algae, and the Cyclops kolensis Lilljeborg (Fij = +0.9) copepods in the past century. The proportion of Chlorophyta decreased from 63% to 17%; the Cyanophyta increased from 3% to 11% in the total biomass of phytoplankton; and the proportion of Cladocera and Rotifera increased to 26% and 11% in the biomass of zooplankton, respectively. Human activity makes an additional contribution to the eutrophication of coastal waters. The Dinobryon species, the cosmopolitan A. formosa and F. radians, dominated phytoplankton, and filamentous algae, Spirogyra, dominated at the bottom in the area with anthropogenic impact. The trophic level was higher than at the unaffected background site: the saprobity index varied from 1.45 to 2.17; the ratio of eutrophic species to oligotrophic species ranged from 1:2 to 3:1, and the ratio of mesosaprobiont biomass to endemics biomass ranged from 2:1 to 7:1. Currently, the boundaries of eutrophication zones of shallow waters in Lake Baikal are expanding, and its coastal zone has acquired features typical of freshwater bodies of the eutrophic type.

“…Spirogyra species were found in freshwater habitats under moderately eutrophic or mesotrophic conditions (Novis 2004, Stancheva et al 2013, Sherwood et al 2018. They mostly occurr in benthos (Volkova et al 2018) but they can also be found in plankton (Kravtsova et al 2020).…”

Although planktonic algae are a basic component of freshwater ecosystems, studies on their diversity and species distribution are still not in satisfactory numbers. This study aims to contribute to Turkish freshwater algal flora particularly with the new records reported. A total of 158 Charophyta taxa were determined in the study conducted from 2017 to 2019 in 25 river basins of Turkey. In this study, while the highest Charophyta taxon was found in Sakarya and Batı Akdeniz basins with 50 and 42 taxa, respectively, Burdur basin was the only basin where we did not find the Charophyta species. The highest Charophyta diversity was observed in Girdev Lake (Batı Akdeniz basin) and Işık Dağı Karagöl Lake (Sakarya basin) among the lakes of Turkey's 25 river basins. Thirty-one of these Charophyta taxa represent new records for the freshwater algal flora of Turkey. Of these, 13 species are commonly distributed, while 18 species have rare distribution areas. Morphology, ecology, and distribution of each taxon were also discussed in details.Özet: Planktonik algler tatlı su ekosistemlerinin temel bir bileşeni olmasına rağmen, onların çeşitliliği ve tür dağılımları konusundaki çalışmalar hala tatmin edici sayılarda değildir. Bu çalışma, özellikle raporlanan yeni kayıtlarla Türkiye tatlı su alg florasına katkıda bulunmayı amaçlamaktadır. 2017-2019 yılları arasında Türkiye'nin 25 nehir havzasında yapılan bu çalışmada toplam 158 Charophyta taksonu tespit edilmiştir. Bu çalışmada, en yüksek Charophyta taksonuna sırasıyla 50 ve 42 takson sayısıyla Sakarya ve Batı Akdeniz havzalarında rastlanırken, Charophyta türüne rastlamadığımız tek havza Burdur olmuştur. Türkiye'nin 25 akarsu havzasındaki göller arasında en fazla Charophyta çeşitliliği Girdev Gölü (Batı Akdeniz havzası) ve Işık Dağı Karagöl (Sakarya havzası)'de görülmüştür. Tespit edilen bu Charophyta taksonlarının 31'i Türkiye'deki tatlısu alg florası için yeni kayıt niteliğindedir. Bunlardan 13 tür yayılış alanı olarak yaygın iken, 18 tür nadir yayılış alanına sahiptir.

“…In conditions of increased load on the ecosystem of the lake, which has already led to a change in the species composition of its inhabitants (Kravtsova et al, 2020), there is an urgent need for regulatory measures on the part of the competent authorities. Quantitative information, even in hypothetical scenarios such as those presented in the report, may be useful.…”
