At least 488 relevés belonging to the class Festuco-Brometea were analyzed using the TWINSPAN algorithm, and 8 distinctive clusters were obtained, recognized as alliances of the order Stipo pulcherrimae-Festucetalia pallentis. A new alliance, Bromopsido cappadocicae-Asphodelinion tauricae, was ascribed to the Crimean Mountains and the presence of two alliances, Diantho lumnitzeri-Seslerion albicantis and Genisto tetragonae-Seselion peucedanifoliae, was confirmed as new for this vegetation in Ukraine. Unlike in the Pannonian Basin, Bromo pannonici-Festucion csikhegyensis alliance communities mentioned in the literature do not occur in Ukraine. Centaureo carbonatae-Koelerion talievii has been provisionally transferred from Festucetalia valesiacae to the order Stipo pulcherrimae-Festucetalia pallentis.

Evaluation of the habitat conservation importance based on multitaxon studies allows for optimizing selection of priority sites. Botanical research of xerothermic habitats in the Kryvorizkyi Iron Ore Basin has been conducted since 2012, while spiders were investigated for the first time in 2017. In the four study sites, we recorded 265 vascular plant species (23 under protection) and 95 spider species (19 are rare). Both vegetation and spider communities of the site Zelena Gully are well preserved and rich in rare and threatened species (18 plant and 11 spider species), which confirms its value as a priority site of the Emerald Network. Chervona Gully and the Slate Rocks should be included in the network. Frequent fires and intensive grazing in Khrystoforova Gully affect the spider diversity, decreasing the number of specialist and rare species, while early flowering plants benefit from this disturbance. Nevertheless, its vegetation is poorer than in Zelena and Chervona gullies. Inclusion in the Emerald Network is critically important to the investigated sites, since expansion of mining activities is constantly threatening natural habitats in industrial regions.","PeriodicalId":39239,"journal":{"name":"Hacquetia","volume":"20 1","pages":"225 - 242"},"PeriodicalIF":0.5,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43318490","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}

During this period, Covid-19 allowed only one live event, the 14th EDGG Field Workshop to the alpine vegetation of Switzerland, organised ad hoc as a replacement for the cancelled Field Workshop in the Ukrainian steppes. The cancelled Eurasian Grassland Conference in Spain found a partial replacement in “Talk Grasslands!”, a series of online talks during winter 2020/2021. EDGG’s own diamond open access periodical, Palaearctic Grasslands, is a novel combination of scientific journal, photo magazine and member newsletter. With five issues during the reporting time it contributed much to EDGG’s attractiveness. EDGG edited four Special Features in international journals (Tuexenia, Hacquetia, Flora) and contributed 13 chapters on grasslands and shrublands of the Palaearctic biogeographic realm to the Encyclopedia of the world’s biomes. EDGG’s vegetation-plot database GrassPlot with multi-scale and multi-taxon diversity data of grasslands and other open habitats of the Palaearctic is now integrated into the EDGG website with the GrassPlot Diversity Explorer.","PeriodicalId":39239,"journal":{"name":"Hacquetia","volume":"20 1","pages":"171 - 176"},"PeriodicalIF":0.5,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47112781","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}

The genus Sesuvium has not yet been studied in detail in the Southern Cone (Argentina, Southern Brazil, Chile, Paraguay and Uruguay), which has led to a misidentification of numerous specimens as S. portulacastrum. As part of the ongoing floristic, taxonomic and ecologic studies in Argentina, we revise the genus Sesuvium for the Southern Cone. This study is based on field investigation, examination of herbarium specimens, and revision of literature. The taxonomic treatments, maps of distribution, detailed descriptions, photographs, an illustration, a dichotomous key and a comparative table to differentiate the species of the genus Sesuvium occurring in the Southern Cone are presented. Finally, ecological, morphological, and taxonomic aspects of the species are discussed. The new combination of S. americanum (≡ Trianthema americanum Gillies ex Arn.; = S. verrucosum Raf.) is proposed. Lectotypes for three names are here designated (S. revolutifolium Vahl ex Willd.; S. revolutifolium Lam., and S. parviflorum DC.). Four species should be accepted for the Southern Cone: S. americanum, S. humifusum, S. mezianum and S. sessile. Furthermore, S. portulacastrum is excluded from the flora of the Southern Cone.","PeriodicalId":39239,"journal":{"name":"Hacquetia","volume":"20 1","pages":"33 - 48"},"PeriodicalIF":0.5,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46783241","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}

We conducted an analysis of the plant species that grow on the Elbasan, Albania fortress walls. Walls vary in age from 4th to 21st century, and in composition. On 71 walls we assessed 2787 plants of 35 species and recorded plant size, presence of flowers or fruits, height from the ground, crevice depth, wall aspect, wall age and composition, and distance to nearest opposing wall. Eleven species, two of which were ferns, composed 93.8% of the plants. The vast majority of plants flowered and fruited on the walls. Plant density ranged from 0.1–70 plants/m2. Species distributions varied significantly based on height on the wall, crevice depth, aspect and distance to the opposing wall. These differences may be influenced by dispersal mechanisms, moisture, substrate composition, and other important environmental factors. For example, Antirrhinum majus was generally found high on south facing walls in deep cracks whereas Umbilicus rupestris was found lower on north facing walls in shallower cracks. It is important that older walls colonized by plants be maintained such that a native flora can persist where natural rocky features are lacking.","PeriodicalId":39239,"journal":{"name":"Hacquetia","volume":"20 1","pages":"81 - 90"},"PeriodicalIF":0.5,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45875925","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}
