The work was carried out at the Scientific Centre for Zoology and Hydroecology, National Academy of Sciences, Republic of Armenia in the period 2019–2023. The material was from our own collections, as well as from collections of insects and mollusks of the Institute of Zoology. The identification and collection of insects and mollusks were done using standard methods.   Results. An overview of some groups of invertebrates in the Erebuni State Reserve is here provided for the first time. As a result of the research, 35 species of Diptera, 15 species of Coleoptera, 44 species of Lepidoptera,10 species of aphids and 12 species of mollusks were identified. Some species are listed in the “Red Book” of Armenia and are under the protection of the state, and there are rare species and species found in the Republic of Armenia only in the reserve. 15 species of insects identified by us develop on 4 plant species included in the “Red Book” of Armenia.   Conclusion. The Erebuni State Reserve is represented by a rather diverse and valuable fauna of invertebrates studied by us, including a number of rare and protected species. Species of invertebrates associated in their development with valuable wild, economically important and protected plants have been identified in the reserve. Identification of species diversity and trophic relationships of some groups of insects that develop on rare and protected plants of the reserve is relevant for natural areas under state protection, of which the Erebuni State Reserve is one.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"18 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140512158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such integrated studies of these groups of organisms are poorly known. Fungi, including lichenized fungi, are essential components of forest ecosystems. Data on their diversity and substrate distribution can provide important information on the condition and biological value of the forests studied.   Material and Methods. The main method of the fieldwork was the \"1‐ha method\". For the alpha‐diversity study, two 1‐ha sample plots were established in well‐preserved forest areas: the first one in a site of mixed broad‐leaved forest with lianas, and the second one in communities dominated by Carpinus betulus and Quercus robur. The specimens were collected from all variety of woody substrate within plots in spring and autumn 2023.   Results. We have revealed 89 species of lichens and 60 species of aphyllophoroid fungi. The lichen families Arthoniaceae, Lecanoraceae, Physciaceae, Ramalinaceae and Roccellaceae contain 47.2 % of all species. High proportion of lichens with Trentepohlia photobiont (29.2 %), significant number of Arthoniomycetes (Arthoniaceae, Lecanographaceae, Roccellaceae) and crustose lichens (75.3 %) have been noted. Among the aphyllophoroid fungi identified in the sample plots, 11 species are new to Dagestan, including three species (Antrodia leucaena, Coronicium gemmiferum, Steccherinum litschaueri) recorded for the Caucasus for the first time. Fourteen species are new to the Samursky National Park.   Conclusion. The study of alpha diversity and substrate preferences of xylobionts revealed the richest and most specific phorophytes, as well as some ecological features of the surveyed plots. Most of the species were found on the bark and wood of Carpinus betulus, Populus alba and Quercus robur. The majority of species reported for the first time for the region have been recorded on these tree species. We expand the number of known species on Populus alba, on which only few species were previously known. High proportion of lichens with the Trentepohlia photobiont and the predominance of crustose species were revealed. In terms of basidiomata morphology, corticioid fungi dominated over polypores and clavarioids in general. The leading ecological and trophic group of aphyllophoroid fungi are saprotrophs. Revealed features indicate a significant contribution of the wood of the main forest‐forming tree species to the preservation of the species richness of myco ‐and lichen biota.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140512197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
