“…The pH varies depending on the season, in the epilimnion from May to September it varies between 8.0-8.6. The lakes are characterized by a low mineralization of water, i.e., 0.1-0.3 g/L, with the predominance of hydrocarbonate ions and a rich microelement water composition (Krupnova 2014;Krupnova 2017).…”

Mashkova IV, Krupnova TG, Kostryukova AM, Vlasov NE. 2018. Short Communication: Distribution of dragonflies (Odonata: Insecta) in South Ural lakes, Russia. Biodiversitas 19: 202-207. This paper studies the diversity and distribution of Odonata (Insecta) in the South Urals region lakes such as Lake Large Miassovo, Lake Small Miassovo, Lake Ilmenskoe, Lake Savelkul and Lake Baraus. We revised dragonflies in five lakes during May-September 2014-2016. Dragonflies and larvae were identified up to the species. As results, 36 species (12 Zygoptera and 22 Anisoptera) belonging to 15 genera were recorded. To compare the similarities of dragonfly communities of different lakes we used the Canonical Correspondence Analysis (CCA) according the Jaccard index. Comparing the number of records of odonate species for selected lakes in our study, we found that the small richness of species was typical for lakes Savelkul and Baraus (22% and 25% of the total number of species, respectively) and the large values of the species richness was obtained for lakes Small Miassovo, Ilmenskoe and Large Miassovo (50%, 72%% and 80% of the total number of species, respectively).

“…Lake Ilmenskoe is more studied than Lake Argayash and Lake Savelkul. There are several earlier reports on the phytoplankton of Lake Ilmenskoe, which explore its species composition, quantitative and eco-geographical characteristics (Krupnova et al 2014, Krupnova et al 2017. There are also studies on the zooplankton communities, macrophytes and mollusks a, b, Kostryukova et al 2016.…”

Kostryukova AM, Krupnova TG, Mashkova IV, Gavrilkina SV, Nikita O. Egorov NO. 2018. Phytoplankton diversity in threelakes of South Ural, Russia. Biodiversitas 19: 1459-1467. Preservation of water ecosystems in their natural state is of great significance.Phytoplankton is one of the biotic indicators of the lake trophic status and ecological state. This study deals with phytoplankton diversityof three lakes of South Ural, Russia. The studied lakes represented different trophic states: Lake Savelkul was oligo-mesotrophic, LakeIlmenskoe was mesotrophic and Lake Argayash was eutrophic. The species composition of common phytoplankton was recorded inJune-July months during 2015 and 2016. The Cyanophyta (blue-green algae) species were dominant in Lake Ilmenskoe(42-64%) andLake Argayash(55-70%). The Bacillariophyta (diatom algae) species were dominant in the Lake Savelkul(40-66 %). The most commondiversity indices namely the Shannon Index, Simpson Index and Margalef Index were determined and the data was also analysed usinggraphs. The graphs were constructed by the similarity calculating method on the basis of the Sorensen-Czekanowski coefficient.Diversity indices confirm the higher species richness of the microalgal community of Lake Ilmenskoe, classified as mesotrophic. It wasshown that the lakes have sufficiently high biodiversity and high ecosystem resilience. Further, statistical analysis (CCA) revealed thatorthophosphate-phosphorus, nitrite-nitrogen and pH were the most significant environmental factors influencing phytoplanktoncommunity of the lakes studied.

“…Aquatic organisms population recovery (National Research Council 1992) is an important factor of lake ecosystem recovery. Mollusks are an important part in food chains of freshwater lake ecosystems (Runck 2007) and they play a major role in distributing elements between the lake water and bottom sediments (Hussain and Pandit 2012;Krupnova et al 2015;Krupnova et al 2017). There is no study of mollusks and limited studies (Jenderedjian et al 2012;Shcherbina 2013) of benthic macroinvertebrate community in Lake Sevan during reсent years.…”

Mashkova IV, Krupnova TG, Kostryukova AM, Harutyunova LJ, Varuzhan HS, Egorov NO. 2018. Short Communication:Mollusks biodiversity of Lake Sevan, Armenia. Biodiversitas 19: 1509-1513. The paper considers mollusks biodiversity in the freshwaterlakes of Lake Sevan, Armenia. Lake Sevan is the largest water body in Armenia and one of the largest freshwater lakes in Eurasia. Since1930 it has been actively used for irrigating Ararat plain and in hydropower. So, its water level fell by 20 m, and its volume became40% less. Since mid-2000 when two tunnels had been built water level started to grow. For the last 6 years, water level was reported togrow. As a result of our study, 11 aquatic mollusks species (10 gastropod and 1 bivalve taxa) were currently found living in the Sevanlake. We found Lymnaea stagnalis (Linnaeus, 1758), Radix auricularia (Linnaeus, 1758), R. tumida (Held, 1836), R. balthica(Linnaeus, 1758), R. lagotis (Schrank, 1803), Galba truncatula (O. F. Müller, 1774), Planorbis planorbis (Linnaeus, 1758),Bathyomphalus contortus (Linnaeus,1758), Gyraulus acronicus (Férussac, 1807), Valvata piscinalis (O. F. Müller, 1774), Euglesacasertana (Poli,
