The first association is confined to the southern tundra subzone of the West Siberian sector of the Arctic, while the second one to the East European sector of the Arctic, where the subassociations alternate along a gradient from the north of the typical tundra subzone to the south of the southern tundra subzone. The new association Arctagrostio latifoliae–Eriophoretum vaginati Lavrinenko O. et Lapshina ass. nov. has been categorized as zonal tundra vegetation.

A marker sign of changes of seed-cones structure is the appearance of an aril from under the scales. At this time, there is an active thickening of the cuticle of the epidermic cells of the seed, sclerenchymatization of zone I of mesotesta cells and obliteration of zone II, differentiation of cells in the chalaza area. The nucellus is reduced, the endosperm and embryo grow, and oil droplets appear in the cells of the endosperm.

The syntaxonomic analysis resulted in the description of two associations of the order Agropyretalia intermedio–repentis, the class Artemisietea vulgaris, which are new both for science and the Southern Urals region: Lactucо tataricaе–Psathyrostachyetum junceae ass. nov. and Sisymbrietum volgense ass. nov. They are found in the steppe zone of the Republic of Bashkortostan, Orenburg and Chelyabinsk Regions, along the roadsides of transport routes, less often in wastelands in settlements. Communities dominated by Psathyrostachys juncea are encountered along the roadsides and slopes of highways in the southern part of the Trans–Urals region of the Republic of Bashkortostan. A characteristic feature of the communities of the association Sisymbrietum volgense is the dominance of the invasive Sisymbrium volgense, which settles actively along the transport routes throughout the entire South Urals region. The DCA ordination of the communities of the order Agropyretalia intermedio–repentis confirmed the results of the syntaxonomic analysis and demonstrated significant differences in the ecology of various cenoses by the following ecological factors: moistening, soil texture and structure, soil fertility, and the thermo-climatic factors. The described syntaxa form the most xerophytic branch of the order Agropyretalia intermedio–repentis in the Southern Urals.","PeriodicalId":37724,"journal":{"name":"Botanica Pacifica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67436423","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}
