Cells of euglenoid Trachelomonas Ehrenb. vary in the size, shape and appearance of the external envelope’s ornamentation, as well as internal structure. The loricae are generally similar in color, ranging from light (hyaline, yellowish, golden, reddish, brownish) to dark (brown, black). This study examined the loricae of twelve trachelomonad species, some light (yellow to golden) and some dark (brown). There were no black loricae, suggesting that little or no Mn was taken up by the cells. Though the envelopes differed in surface ornamentation and color, comparative SEM-EDS analyses of all the material studied showed high iron content, silicon mineralization, and no manganese. The degree of iron and silicon mineralization varied. Some loricae had high silicon content (e.g., T. compacta Middelhoeck) and others were more saturated by iron ions (T. manginii Deflandre, T. lacustris Drezep.).

This paper presents the first Polish collections of the species. Hitherto unknown in Poland, R. subarctica is reported from two localities in subalpine belts of the West Tatra Mts and Karkonosze Mts. The morphology of newly collected basidiomata of the fungus is described, illustrated and commented, and some basic chemical parameters of its habitat in the Karkonosze Mts are given.

An examination identified the rust fungus as Puccinia tiliaefolia T. S. Ramakr. & Sundaram. This finding represents a new record for the northwestern Himalayas and the first finding of Puccinia tiliaefolia in India in the last 46 years. A geographical distribution map of P. tiliaefolia is presented.

The paper reports the first comprehensive study of microalgal species composition in four lakes of Volhynian Polissya (northwestern Ukraine), in which 271 species (279 intraspecific taxa) of 11 microalgal phyla were identified. 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. Klebs, Eunotia myrmica Lange-Bert. and E. tetraodon Ehrenb. The lakes, which are almost pristine or are recovering, maintain diverse and valuable algal floras, making them important sites in the Pan-European ecological network.
本文首次对乌克兰西北部Volhynian Polisya四个湖泊的微藻物种组成进行了全面研究，共鉴定出11个微藻门的271种（279个种内分类群）。为每个湖泊确定了四种主要浮游植物组合。Bacillarophyta和Charophyta占分类列表的一半以上（59.2%），分别占94种和66种。Desmidiaceae是最具多样性的科，有44种（47个种内分类群）微藻。这四个湖泊的物种丰富度和组成极不相同，只有8个（2.9%）物种是共同的。切伦斯克湖的藻类种类最多，为137种（144种）。比尔湖、索米恩湖和雷迪奇湖的多样性要低得多，分别有105种、79种（80种）和75种（78种）。提供了许多物种的形态描述、原始显微照片和数字，包括一些以前在乌克兰没有记录的物种：铬藻（Chromulina cf.verrucosa G.a.Klebs）、Eunotia myrmica Lange Bert。和E.tetraodon Ehrenb。这些湖泊几乎是原始的或正在恢复的，保持着多样而有价值的藻类群落，使其成为泛欧生态网络中的重要地点。

Structural transformation of mechanical tissues during the shift from a freestanding to a climbing habit is a characteristic of lianas, which are increasingly abundant in tropical forests. 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.

Rosa rugosa Thunb. is an invasive alien plant which was introduced from East Asia to Europe in the 19th century. 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.
Rosa rugosa Thunb。是一种外来入侵植物，于19世纪从东亚传入欧洲。几十年来，它沿着芬兰海岸蔓延，包括波罗的海的群岛。这种灌木特别生长在沙滩、多石海岸和海滨草地上。在那里，它导致了沿海生态系统的严重变化，并取代了当地的植物物种。本文介绍了芬兰西南部群岛海国家公园及其附近的褐沙鼠的分布和生境偏好。研究区共有205个林分，其中58%位于保护区。系统的调查没有覆盖整个研究区域，所以很可能还有几十个林分未被发现。该物种的林分集中在群岛最具特色的植物群和动物群所在的外岛。收集了所有林分的滨岸类型和面积数据。2008年开始防治工作前，绿僵菌覆盖总面积为7277平方米。最大的林分发生在Örö岛上，被消灭前林分面积约2500 m2，所有林分的中位数为6 m2。六个最大的林分中有五个位于沙滩上，但石质海岸是最常见的栖息地类型。

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.

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}
