The species of winter- and spring emerging plecopterans inhabiting the northern slopes of the Central Caucasus (territory of the Republic of North Ossetia-Alania, Russia) were examined. A total of 33 species were found at 59 sites. These findings expand the knowledge of ecology and phenology of six species for which we knew little. New localities were detected for a few rare stoneflies: Filchneria balcarica Balinsky, 1950, Plesioperla sakartvella (Zhiltzova, 1956), P. brachystyla Zhiltzova, 1988 and others.
This dataset contains the digitized treatments in Plazi based on the original journal article Cherchesova, S. K, Shioloshvili, M. N, Yakimov, A. V., Nemno, E. V., L`vov, V. D., Kovilyaeva, N. E. (2012): Stoneflies (Insecta, Plecoptera) Of Kabarda-Balkarian Republic (The Central Caucasus). Illiesia 8 (19): 174-181, DOI: http://doi.org/10.5281/zenodo.4753237
The paper provides information about the fauna of amphibious insects that live in the river Tsraudon, discusses the ecology of species, the dynamics of species diversity. The collected material in the classes Turbellaria (Tricladida), Crustacea (Amphipoda), Arachnida (Hydracarina), Insecta (Ephemeroptera, Plecoptera, Trichoptera, Odonata, Diptera), Gastropoda (Pulmonata), is represented by 55 species from 29 families; among zoobenthos, Insecta dominates (87 %). All insects except the order Odonata are represented by litoreophilic, stenothermic species.
The article is devoted to the project on creation of a digital database on flora and fauna of North Ossetia. The paper discusses the need for biodiversity databases and digitalisation of biological collections. Information on existing biological databases is given, and the experience of developing an interactive web portal “Nature of Ossetia”, its functionality and the structure of the created database is described.
The fauna of Karachay-Cherkessia has also been studied [Brekhov, 2009].Studies on the fauna of water beetles of such regions as Stavropol Krai and North Ossetia have not been published yet.Moreover, there are only scattered records of species in Chechnya and Ingushetia.This shows the importance of the current study.Several papers present insufficient data on the fauna of the water beetles of North Ossetia [Zaitsev, 1927[Zaitsev, , 1928;;Shatrovsky, 1984; Fery, 2009].Tarnogradsky and Popov [1932-1933], as a result of their expedition (9.VIII-9.X.1930), studied the fauna of the waterbodies of Ossetia, Ingushetia and Georgia as a potential habitat of Lymnaea truncatula Müll., the intermediate host of Fasciola hepatica L., 1958.They provided detailed lists of hydrobionts (diatoms, green algae, protists, rotifers, mollusks, crustaceans, aquatic and semiaquatic insects) for 33 types of waterbodies of montane and submontane regions.However, only orders of aquatic and semiaquatic insects were given for specific localities (except Diptera, which were identified to genus).Thus, the mentioned paper records 24 species of water beetles of North Ossetia without specified localities.North Ossetia is located on the northern slopes of the Central Caucasus Mountain and adjacent plains.Despite the small area, the territory of North Ossetia has a variety ABSTRACT.An annotated species list of water beetles on the territory of North Ossetia is provided (65 species of seven families): Dytiscidae (31 species), Noteridae (2), Gyrinidae (5), Haliplidae (8), Hydrophilidae (17), Hydrochidae (1) and Spercheidae (1).New sampling sites are given for 55 species.A total of 30 species are recorded for the first time in North Ossetia.РЕЗЮМЕ.Приведён аннотированный список водных жесткокрылых, выявленных на территории Северной Осетии -65 видов из 7 семейств: Dytiscidae (31 вид), Noteridae (2), Gyrinidae (5), Haliplidae (8), Hydrophilidae (17), Hydrochidae и Spercheidae по 1 виду.Приводятся новые пункты сборов для 55 видов.30 видов впервые указываются для фауны Северной Осетии.
The study is devoted to the study of individual indexes saprobity larvae of caddisflies (Trichoptera) from water bodies of Kabardino-Balkaria (Central Caucasus). The results of the work are based on years of in-situ observa-tions, qualitative and quantitative samples of hydrobionts from the rivers and streams of the CBD. Sampling was performed with the help of water nets (qualitative test) and bentometra Sadovsky (quantitative samples). It is established that the fauna of caddisflies Kabardino-Balkaria are endemics and subendemics Caucasus. This cir-cumstance did not allow to use them for biological assessment of water quality in rivers and streams. Our studies have clarified the indicator weight of about 50 species of caddisflies. It was found that the majority of species of caddisflies dwells in spring the rivers and streams, and only a small part of it inhabits rivers with glacier power. All types with very few exceptions belong to the group of xenosaprobic and oligosaprobic. The work gives the individual the saprobity index for most species of caddisflies. The results of investigations are used for creation of the system of surface water quality biomonitoring in the North Caucasus.
The caddisfly Plectrocnemia latissima Martynov 1913 inhabits springs, streams and rivers of the northern slopes of the Central Caucasus. Aspects of the biology of this species are reported here. Its larvae require a high oxygen concentration and can be used as a good indicator of water quality.
