Lichens are recognized as bioindicators of ecosystem processes associated with environmental disturbances. However, its evaluation in the time requires systematic records of biodiversity which are non-existent in the Katalalixar National Reserve. The aim of this study was to catalog the richness and distribution of lichen biota of Katalalixar National Reserve, not only by identifying the species but interpreting them in their ecological and biogeographic context. By random sampling in Nothofagus nitida, Pilgerodendron uviferum forests and peat bogs 70 species were identified, belonging to 32 families and 65 genera. A high number of endemism was found, with 34% of the species endemic to Southern South American and the Chilean endemic Pseudocyphellaria guzmanii constitutes a new record for the Aisen Region.

Abstract Alien invasive woody plant species, particularly those associated with nitrogen-fixing bacteria, are of special concern, because they may cause drastic changes in entire ecosystems. Although most of invasive species of Lithuania originate from other continents, one of these, Cytisus scoparius, is native to Europe. Fast spread of this species in Lithuania and its invasion to forest, coastal and continental sand, occasionally grassland habitats, stimulated us to study demographic structure of its populations. The aim of this research was to evaluate density, life stage and age structure of the populations, and to analyse relationships of the age of individuals with their life stages, height and stem diameter. Five populations were studied in the western, southern and eastern parts of Lithuania in July–August 2017. For the study, we selected stands of this species occupying at least 0.1 ha in a uniform habitat. We applied sampling plot method, and studied at least 100 individuals in each population, excluding seedlings. The age, life stage, height and stem diameter of 583 individuals were studied. The average density of individuals ranged between 5.15 individuals/m2 and 15.40 individuals/m2. Juvenile individuals reach the stage of vegetative adults on the second or third growth season, occasionally on the third year they reach even the stage of generative adults. The average age of juveniles was 1.10 years, of vegetative adults it was 2.99 years and 6.26 years of generative adults. The oldest generative individual was 28 years old. Linear regression analysis of the relationship between the plant age and the stem diameter revealed that the age predetermined the stem diameter variance by 81.0% in the studied populations. This study revealed that densities of C. scoparius individuals of all life stages in disturbed and undisturbed habitats were sufficient to sustain longevity and further expansion of populations. Therefore, appropriate measures for control and eradication of this species should be applied, particularly in the habitats of high conservation value.

Abstract The paper presents the data on taxonomical diversity and distribution patterns and dynamics of the Corispermum species in the Baltic States over the last hundred years. Field studies and the herbarium material analyses were carried out. The distribution dynamics was analysed by comparing all known localities of the Corispermum species in two time periods: by 1990, and from 1991 to the present. Analysis of the herbarium material confirmed that currently there are four species in the Baltic States: Corispermum hyssopifolium, C. declinatum, C. intermedium and C. pallasii. The only endemic species to the Eastern Baltic Region, C. intermedium, is considered as typical for annual vegetation on embryonic shifting dunes and other coastal habitats. In Lithuania, this species is considered extinct or almost extinct, as has not been found for more than 30 years, only its hybrids with C. pallasii. The largest and most stable population of C. intermedium has been found on the eastern shore of the Gulf of Rīga in Latvia. Other species such as ephemerophytic C. hyssopifolium and C. declinatum also prefer dry and disturbed habitats. Both have become less frequent in recent years. However, potentially invasive C. pallasii has been observed in the region with increasing distribution dynamics. The Estonian and Latvian herbaria analysis confirmed that all specimens previously identified as C. algidum after re-examination were identified as C. pallasii or C. intermedium and more often as hybrid C. intermedium × C. pallasii.
摘要:本文介绍了近百年来波罗的海国家草属植物的分类多样性、分布格局和动态。进行了野外研究和植物标本室材料分析。通过比较到1990年和1991年至今这两个时期的所有已知地点，分析了其分布动态。对植物标本馆资料的分析证实，目前在波罗的海国家有四种:Corispermum hyssopifolium, C. declinatum, C. intermedium和C. pallasii。东波罗的海地区唯一的特有种是C. intermedium，被认为是在胚胎移动沙丘和其他沿海生境上的典型一年生植被。在立陶宛，这个物种被认为已经灭绝或几乎灭绝，因为30多年来没有发现过，只有它与C. pallasii的杂交。在拉脱维亚的Rīga湾东岸发现了最大和最稳定的中间C.种群。其他种类，如短生植物C. hyssopifolium和C. declinatum也喜欢干燥和受干扰的栖息地。近年来，这两种情况都变得不那么频繁了。然而，该地区已观察到潜在入侵的pallasii，其分布动态不断增加。爱沙尼亚和拉脱维亚的植物标本分析证实，所有在重新检查后被鉴定为C. algidum的标本都被鉴定为C. pallasii或C. intermedium，更常见的是C. intermedium × C. pallasii的杂交品种。

Abstract A study of the impact of short-term abandonment on the structure and functions of semi-natural dry grasslands in Lithuania was performed. Data on the abundance of vascular plant species, hay and litter samples were collected. At the same time, plant functional traits and Ellenberg indicator values were used to evaluate the effect of abandonment on the structure and functions of semi-natural dry grasslands. The results showed that litter layer was significantly heavier in unmanaged plots compared to that in managed plots. The vascular plant species pool was higher in managed plots, where 62 vascular plant species were identified, while in unmanaged plots 46 species were identified. The species richness was significantly higher in managed semi-natural dry grasslands. Unmanaged plots had 12.3 ± 0.6 species, while managed plots had 17.7 ± 1.2 species per one square metre. Functional plant traits were similar in mowed and abandoned communities, while functional diversity was lower in unmanaged communities. These results are a clear indicator that the managing of semi-natural dry grasslands creates heterogeneity of the environment.

Abstract The aim of the study was to investigate the potential beneficial effects of exogenous application of methyl jasmonate (MeJa) and phenylurea cytokinin (4PU-30) on zucchini (Cucurbita pepo L.) cotyledons subjected to high temperature (HT) and combined HT plus excess copper (Cu2+) stress. Compared to HT stressed zucchini cotyledons, exposure to excess Cu2+ prior to HT treatment inhibited the growth, decreased superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GR) activities, increased glutathione-Stransferase (GST) and peroxidase (Px) total activities, and induced new enzyme isoforms (GST4, GST8, and Px4). The effect of MeJa on the double-stressed plants was to increase SOD, GPx and Px total activities and stimulate the activity of GST8, GST9, GST10, SOD5, Px3 and Px8 isoenzymes. In addition to SOD, GPx and Px, 4PU-30 increased GST total activity, up-regulated Px1 and GR1, and had a higher stimulatory effect on SOD5, Px3, GPx3, GST9 and GST10 activities. Copper, 4PU-30 and MeJa treatments changed the abundance and pattern (MeJa) of soluble zucchini polypeptides in a specific manner. MeJa and especially 4PU-30 applied alone, or in combination, stimulated the growth of later HT-treated cotyledons. 4PU-30 counteracted better than MeJa in the HT+heavy metal-caused inhibition of the growth. The data indicated that both MeJa and 4PU- 30 may protect the zucchini plants from high temperature and combined high temperature plus excess copper stress, but 4PU-30 was more effective; the protective effect was related to the changes in the gene expression, total antioxidant enzyme activities and the activity of individual isoforms of the enzymes.

Abstract We conducted this study to determine and compare the content of phenolic compounds and flavonoids in the argan and olive leaves as well as their antioxidant capacity in aqueous, methanolic, and ethyl acetate extracted fractions. In vitro antioxidant activity was evaluated in comparison with synthetic antioxidants by assessing DPPH• radical scavenging capacity, ferric reducing antioxidant power, scavenging ability by inhibiting the β-carotene/linoleic acid emulsion oxidation, and by the ABTS radical scavenging activity assay. Total phenolic content in argan samples ranged from 221.69 ± 2.07 to 1.32 ± 0.01 mg GAE/g DW and in olive samples from 144.61 ± 0.82 to 1.21 ± 0.02 mg GAE/g DW. Total flavonoids content in argan samples varied from 267.37 ± 1.12 to 25.48 ± 0.02 mg QE/g DW, while in olives from 96.06 ± 0.78 to 10.63 ± 0.05 mg QE/g DW. In vitro antioxidant studies strongly confirmed the antioxidant potency of argan and olive leaves and their richness in secondary metabolites that are effective in free radicals scavenging and metal chelating capacities, indicating their antioxidant power.

Abstract The floristic survey of the desmids in lakes of the southern part of Middle Urals revealed nine species representing the genus Euastrum and eight taxa belonging to the genus Micrasterias. Among them, four taxa (Euastrum germanicum, E. verrucosum var. alatum, Micrasterias fimbriata, M. mahabuleshwarensis var. wallichii) were new records to the Ural Region, whereas the other four taxa (Euastrum verrucosum, Micrasterias americana, M. furcata and M. truncata) were found for the first time in Middle Urals. Canonical correspondence analysis, which was performed to assess habitat preferences of the studied algae, showed that most species were more abundant in slightly acidic water and occurred predominantly in benthic habitats.

Abstract Molecular autograph of trn/mat-K gene was used as one of the important candidate marker in addressing the questions of systematics and barcoding of medicinal plants. Features of trn/mat-K gene in Isodon rugosus (Lamiaceae) were assessed for the first time (NCBI GenBank Accession Number: MH939199.1). Sequence of 756 bp length was amplified by the universal matK primers (matK472F and matK1248R) in the cpDNA of the plant. It was reported to contain trnK gene (>1…..50; >746…..756), partial sequence; and matK gene (>51…..745), partial coding DNA sequence. Alignment search and analysis showed that only nine different Isodon species are currently available for matK sequences with repeated copy of submissions in GenBank. The matK sequences of I. rugosus was reported with 34.2 (G + C)% and 17 variable sites (VS), out of which seven were singleton (ST) and 10 sites were species-specific parsimoniously-informative (PI) that could be used to differentiate I. rugosus from other species as well as to authenticate the taxon. Phylogenetic analysis resulted into monophyletic clustering of I. rugosus near to the clade having I. coetsa by both maximum likelihood (ML) and maximum parsimony (MP) methods. Clades obtained in ML tree were more informative as compared to MP tree.

Alignment search and analysis showed that only nine different Isodon species are currently available for matK sequences with repeated copy of submissions in GenBank. The matK sequences of I. rugosus was reported with 34.2 (G + C)% and 17 variable sites (VS), out of which seven were singleton (ST) and 10 sites were species-specific parsimoniously-informative (PI) that could be used to differentiate I. rugosus from other species as well as to authenticate the taxon. Phylogenetic analysis resulted into monophyletic clustering of I. rugosus near to the clade having I. coetsa by both maximum likelihood (ML) and maximum parsimony (MP) methods. Clades obtained in ML tree were more informative as compared to MP tree.","PeriodicalId":55127,"journal":{"name":"GAYANA BOTANICA","volume":"107 1","pages":"100 - 95"},"PeriodicalIF":0.3,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76844712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract The paper presents a brief biography of Professor Povilas Snarskis, and discusses the importance of his work for Lithuania. After defending PhD at Vytautas Magus University, P. Snarskis was able to collect invaluable data on the Lithuanian floristic diversity and distribution. He actively participated in the development of the Lithuanian higher education. In 1947, he became a professor and taught botany at Vilnius University and Vilnius Pedagogical Institute. During his professional career, P. Snarskis has published about 60 research and popular science works. He was a co-author of Flora of Lithuanian SSR and his three guides to native vascular plants still have their high value. The number of Snarskis’ herbarium specimens deposited at Vilnius University Herbarium (WI) and the Nature Research Centre, Institute of Botany Herbarium (BILAS) exceeds 20.000. P. Snarskis was an innovator, who used his logic and creativity, and constructed guidelines to achieve his goals in difficult historical times.
