Four dominant phytoplankton assemblages were determined for each lake. Bacillariophyta and Charophyta formed more than half (59.2%) of the taxonomic list, accounting for 94 and 66 species respectively. Desmidiaceae was the most diverse family, with 44 species (47 intraspecific taxa) of microalgae. The four lakes are highly dissimilar in species richness and composition, having only 8 (2.9%) species in common. Lake Cheremske had the highest number of algal species – 137 (144). Lake Bile, Lake Somyne and Lake Redychi were much less diverse, with 105, 79 (80) and 75 (78) species respectively. Morphological descriptions, original micrographies and figures are presented for a number of species, including some not previously documented in Ukraine: Chromulina cf. verrucosa G. A.

The modification of mechanical tissue and the evolution of a new growth pattern serve to increase stem flexibility and conductive efficiency. In Ipomoea turbinata Lag. (Convolvulaceae), the stem thickens via the formation of two distinct types of successive cambia: functionally normal successive cambia (producing xylem centripetally and phloem centrifugally), and inverse cambia (producing xylem centrifugally and phloem centripetally). The former originates from pericyclic derivatives (parenchyma cells located outside the primary phloem), while the latter originates from the conjunctive parenchyma located on the inner margin of the secondary xylem formed from vascular cambium. The secondary xylem produced by normal cambia is significantly more abundant than the xylem formed by inverse cambia. During primary growth, intraxylary primary phloem differentiates concomitantly with the protoxylem at the periphery of the pith; additional intraxylary secondary phloem is added from adjacent parenchyma cells as the plant ages. During initiation of every successive cambium, middle cells in the meristem give rise to cambium, and cells on either side of it serve as sites for initiation of future cambia. The functional role of inverse cambia remains unknown and awaits further experimental studies.","PeriodicalId":56362,"journal":{"name":"Polish Botanical Journal","volume":"62 1","pages":"87-97"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/PBJ-2017-0003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49001923","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}

Over the decades it has spread along the Finnish coast, including the archipelagos of the Baltic Sea. The shrub grows particularly along sandy beaches, stony shores and seashore meadows. There it leads to serious changes in coastal ecosystems and replaces native plant species. This paper presents the distribution and habitat preferences of R. rugosa in and near Archipelago Sea National Park in SW Finland. We identified 205 stands in the study area, 58% of them in protected areas. Systematic inventories do not cover the whole study area, so it is likely that dozens of stands remain undiscovered. Stands of the species were concentrated on the outer islands, where the archipelago’s most characteristic flora and fauna occur. Data on the shore type and area of all stands were collected. The total area covered by R. rugosa was 7277 m2 before control work started in 2008. The largest stand occurred on Örö Island, covering ca 2500 m2 before its eradication, and the median size of all stands was 6 m2. Five of the six largest stands were on sandy beach, but stony shore was the most common habitat type.","PeriodicalId":56362,"journal":{"name":"Polish Botanical Journal","volume":"62 1","pages":"99-115"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/PBJ-2017-0009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42951271","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}

(Cephaloziellaceae, Marchantiophyta) in Asia, the new species Cephaloziella konstantinovae Mamontov & Vilnet, sp. nov ., from the eastern regions of Russia and from the Republic of Mongolia was discovered. The new species is formally described and illustrated here. Morphologically it is similar to C. divaricata var . asperifolia (Taylor) Damsh. , but differs in its leaf shape and thin-walled, inflated stem and leaf cells. The new species can be distinguished from other Cephaloziella taxa by the following characters: ( i ) female bracts entirely free from each other and from bracteole, ( ii ) perianth campanulate, ( iii ) cells of perianth mouth subquadrate, ( iv ) capsule spherical, ( v ) seta with 8–10 + 4–6-seriate morphology, and ( vi ) elaters with 1–2 spiral bands. Molecular phylogenetic analyses of nrITS1-5.8S-ITS2 and chloroplast trn L-F sequences from 63 samples (34 species, 23 genera) confirm the taxonomical status of the new species. Five specimens of C. konstantinovae form a clade placed sister to a clade of C. elachista (J. B. Jack) Schiffn. and C. rubella (Nees) Warnst.","PeriodicalId":56362,"journal":{"name":"Polish Botanical Journal","volume":"62 1","pages":"1-19"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/PBJ-2017-0001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43583310","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}
