This paper aims to synthesize the studies conducted over time both on Ligularia sibirica species and Ligularia genus. The main objective of the paper is to identify the following research steps necessary for the optimal characterization, monitoring and conservation of the studied species and of its related populations. Ligularia genus includes species adapted to different climatic and environmental conditions from the European and Asian continent. Following the collected scientific material which holds data about L. sibirica, the author found a total of 166 bibliographic sources, of which 107 belong to Romania. The number of scientific materials found in Romania is correlated with the distribution of the L. sibirica species in the country. At European and Asian level, have been carried out phytosociology, genetics, biochemistry, biotechnology and phytopathology studies on Ligularia, while in our country taxonomic studies predominate, being part of some floristic surveys, monographs, etc., which need to be updated and completed.

  • Finnish Botanists and Mycologists in the Arctic1
    525 ARTICLE Finnish botanists and mycologists in the Arctic1 Henry Väre Abstract: Finnish botanists and mycologists have studied Arctic areas and timberline regions since the beginning of the 18th century. Most expeditions to the Kola Peninsula were made between 1800 and 1917 and until 1945 to Lapponia petsamoënsis on the western rim of the Kola Peninsula. Since those years, these areas have been part of the Soviet Union or Russia. Svalbard and Newfoundland and Labrador have been studied repeatedly as well, Svalbard since the 1860s and Newfoundland and Labrador since the 1930s. This article focus- es on Finnish collections. These are deposited in the herbaria of Helsinki, Turku, and Oulu universities, except materials from the Nordenskiöld expeditions, which were mainly deposited in Stockholm. Concerning the Kola Peninsula, collections at Helsinki are the most extensive. The exact number of specimens is not known, but by rough estimation, the number is about 60 000, with an additional 110 000 observations included in the data- base. These expeditions have provided material to describe 305 new taxa to science, viz. 47 algae, 78 bryophytes, 25 fungi, 136 lichens, and 19 vascular plants. This number is an underestimate, as many new species have been described in several separate taxonomic arti- cles. At least 63 persons have contributed to making these collections to Finnish herbaria. Of those, 52 are of Finnish nationality. Key words: bryophytes, fungi, vascularplants, Finnish, Arctic. Résumé : Les botanistes et les mycologues finlandais ont étudié les régions arctiques et les régions de limite forestière depuis le début du 18ème siècle. La plupart des expéditions à la presqu’île de Kola ont été faites entre 1800 et 1917 et jusqu'à 1945 à Lapponia petsamoënsis For personal use only.

  • Present State of Rare Species Ligularia Glauca in Northern Romania
    https://doi.org/10.15551/pesd2019132021 PESD, VOL. 13, no. 2, 2019 PRESENT STATE OF RARE SPECIES LIGULARIA GLAUCA IN NORTHERN ROMANIA Ciprian Claudiu Mânzu1, Cezar Valentin Tomescu2, Alina Georgiana Cîșlariu1 Key words: relict species, nature reserve, historical data, population size, xero- mesophilous grasslands. Abstract. Although the taxonomic issue of Ligularia glauca remains a subject for further research, the "Fânațele seculare de la Calafindeşti" Nature Reserve, maintains its scientific relevance. Dependent on different author’s opinion, this site preserves either the only L. glauca population from Romania, or the only L. carpatica population from the lower altitude xero-mesophylic meadows from Romania. Vegetation description dates from the last 40 years ago and is lacking information regarding the size of L. glauca population. Therefore, within the aim of our study is to inventory L. glauca population from Calafindesti and to highlight the main factors of anthropic origin with a negative effect on this population. Introduction Throughout history, all species experienced periodical range restrictions and expansions. Among the climate relict species, whose geographic distribution has reduced mainly because of changes in climate, the glacial relicts had a wider spread in the cold period of the Quaternary and since the LGM (Last Glacial Maximum) they suffered significant restraints (Hampe and Jump 2011). The habitat fragmentation processes following glaciations affected the characteristics of the remnant glacial relict populations. Their ability to withstand repeated climate changes (Ronikier et al. 2012) determined the relict populations to be of particular interest for studies of phylogeography or genetic diversity conservation (Hampe and Petit 2005). Climate relicts are important components of local and regional biodiversity (Eriksson 2000), serving as models for understanding the effect of climate changes on the actual flora (Thuiller et al.

General Part by Hiroshige KoyAMA Botanical Institute, College of Science, University of Kyoto Abstract This is thefirst part of the taxonomical revision of the Tribe Senecioneae in Eastern Asia. There occur fourteen genera of that tribe. An attempt is made to clarify the relationships among the members from the standpoints of comparative morphology and chromosome study. In the following parts of this paper, the enumeration will be glven concermng to respectlve taxa. Int"roduction • The Senecioneae have custornarily been considered as a distinct tribe of the Compositae, though there are some genera of doubtful position. Fourteen genera a're known in Eastern Asia. All of these genera have correctly been placed in the Tribe Senecioneae, but their definitions are given variously according to the authors concerned. The distribution of inost of these genera is not restric- ted within one botanical region, extending widely to the tempercate Eurasia. [l"he numbeir of the species is naost abundant in Southwest China, ancl accordingly, we can find various forms there. We are at present interested in the taxonomi- cal problems to be settled about the relationship within the members of Eastern Asia, Comprehensive contributions have been made on the classification of these genera." No z-evision has yet been given covering all the members in question.

Some floral micromorphological characters of this species, including shape of anther bases, configuration of anther collars, and anther endothecial tissue cell wall thickenings, are confirmed to perfectly match those of Senecio and this has obviously resulted in the placement of the species within that genus. Chromosome counts indicate S. kumaonensis has 2n = 40, a number common to Senecio and Synotis but not occurring in Parasenecio (the cor- rect generic name for the Asian species previously referred to Cacalia), which has 2n = 52, 58, and 60. The presence of six subterminal-centromeric (st) chromosomes in the karyotype of S. kumaonensis, however, lends strong support to the close relationship of this species to Synotis.

RNDr. Zuzana Münzbergová, Ph.D. Rok obhajoby: 2012 Abstrakt: Dobrá znalost populační biologie, genetické variability a stanovištních charakteristik je nezbytná pro efektivní ochranu vzácných druhů rostlin. Pro svou studii jsem si zvolila kriticky ohrožený druh chráněný směrnicí o stanovištích (příloha II), Ligularia sibirica (L.) Cass.. Hlavním cílem studie bylo stanovit genetickou variabilitu, hlavní stanovištní charakteristiky lokalit studovaného druhu a zhodnotit jejich význam spolu s velikostí populací pro populační dynamiku L. sibirica v České republice a na Slovensku. Populační dynamika byla studována pomocí populačních přechodových matic po dobu čtyř let. Většina sledovaných populací prospívá dobře a pouze populace rostoucí na odvodněných stanovištích mají klesající trend. Analýzy elasticity ukázaly, že přechody, které nejvíce přispívají k růstové rychlosti populací, se liší dle zachovalosti stanoviště. Genetická variabilita byla stanovena pomocí metody isoenzymů.
