The Rybachy and the Sredny Peninsulas are the northernmost part of Murmansk Region in the European part of Russia. While the most part of the Region is covered by boreal forest, the Peninsulas are covered by tundra. The vegetation and flora of Murmansk Region are well studied at present. The Peninsulas were first studied in 1829 by a Finnish botanist Jacob Fellman. The most comprehensive research was conducted in the late 19th - early 20th century. Nevertheless, the species composition of the Peninsulas' flora has changed significantly over the past 100 years due to land use and climate change. The aim of this dataset is to make the data on species occurrences for this territory digitally available via GBIF. To date, more or less complete digital floristic data were provided only by the project for digitising the book "Flora of Murmansk Region" (1953–1966). The present dataset is a part of the project studying the vegetation of the territory. We recorded the information about species frequency and distribution using the relevé method. We present a dataset based on 991 relevés from all vegetation types, which includes 16,289 records of georeferenced plant occurrences that belong to 568 species. There are 23 species of lichens (Ascomycota), 142 species of mosses (Bryophyta), three species of liverworts (Marchantiophyta) and 400 species of vascular plants (Tracheophyta) in the present dataset. The taxonomic diversity and unevenness result from the vegetation sampling. The data were collected in 2008, 2009, 2011, 2014 and 2015. The dataset cannot be considered as a complete vegetation database or a flora checklist, but it contains the occurrences and frequencies of the species from all the vegetation types.

UDK: 581.5(497.6) The beginnings of vegetation research of Bosnia and Herzegovina (B&H), according to Braun-Blanquet’s approach, date back to early 1930s, culminated in the period of 60s-70s, and declined until the end of 20th century. Twenty years after the war B&H vegetation science hasn’t still achieved the pre-war level. The starting point for the preparation of the checklist of vegetation classes was the vegetation database of Bosnia and Herzegovina, which contains 6823 relevés, which were digitized and imported in TURBOVEG database for storage of large relevé datasets. Total of 4780 relevés were collected from 123 references (2906 regularly published, 1331 from grey literature and 543 from manuscripts), while 2043 are unpublished relevés, mainly recorded by the team of the Department of Forest Ecology at the Faculty of Forestry in Banja Luka. Analysis of this dataset suggests that vegetation of Bosnia and Herzegovina comprises 60 classes. According to the overviews of vegetation of Bosnia and Herzegovina published so far, the vegetation dominated by vascular plants numbers 33 and 39 classes respectively. This discrepancy can be partially attributed to different syntaxonomic concepts used in these overviews compared to the latest Checklist compiled at the European level (EuroVegChecklist), which was our guideline, but also to uneven level of elaboration of different vegetation types and geographical regions in B&H. Six classes of forest vegetation share almost 60% of the total number of relevés, while another six classes of various grasslands take another 25%. The other 15% is divided among the rest of 48 classes. Some of the classes without relevés are, in our own opinion, present in B&H, but still need to be confirmed, while the others, even though mentioned in literature, couldn’t be confirmed at the field after extensive research.

AbstractNon-vascular plants associating with arbuscular mycorrhizal (AMF) and Mucoromycotina ‘fine root endophyte’ (MFRE) fungi derive greater benefits from their fungal associates under higher atmospheric [CO2] (a[CO2]) than ambient; however, nothing is known about how changes in a[CO2] affect MFRE function in vascular plants. We measured movement of phosphorus (P), nitrogen (N) and carbon (C) between the lycophyte Lycopodiella inundata and Mucoromycotina fine root endophyte fungi using 33P-orthophosphate, 15 N-ammonium chloride and 14CO2 isotope tracers under ambient and elevated a[CO2] concentrations of 440 and 800 ppm, respectively. Transfers of 33P and 15 N from MFRE to plants were unaffected by changes in a[CO2]. There was a slight increase in C transfer from plants to MFRE under elevated a[CO2]. Our results demonstrate that the exchange of C-for-nutrients between a vascular plant and Mucoromycotina FRE is largely unaffected by changes in a[CO2]. Unravelling the role of MFRE in host plant nutrition and potential C-for-N trade changes between symbionts under different abiotic conditions is imperative to further our understanding of the past, present and future roles of plant-fungal symbioses in ecosystems.

The Transcarpathian plain is the northeastern part of the large Middle Danube lowland in the Transcarpathian region. The length of the plain is 80–90 km, the width is 22–23 km, the height is 102–120 m asl. Within the Transcarpathian plain stands out the Berehiv hills, represented by single volcanic mountains of 300-500 m altitude (Black Mountain – 568 m asl, Shalanka – 372 m asl. and other). The Transcarpathian plain is located mainly on the right bank of the Tisza River. Soil-forming rocks are mostly acidic. The climate of the Transcarpathian plain is humid, temperate and continental. The spontaneous flora of the Transcarpathian plain consists of 1209 species of higher vascular plants. Depending on the ecological and coenotic affiliation of flora species to the main zonal vegetation types, seven florencoenotypes were identified in the territory of the studied region: 1) Immoral (Nemoralophyton) – 375 coenoelements (33.33% of the total number of species). In the composition of the Nemoralophyton the florencoenosvites are distinguished: a) oak-hornbeam (Querceto-carpinetophytum) – 130 coenoelements (10.75%); b) helio-quercetal (Quercetophytum) – 171 coenoelements (14.14%); c) fagetal (Fagetophytum) – 74 coenoelements (6.12%); 2) Meadow (Pratophyton) – 220 coenoelements (18.2%). As a part of the Pratophyton the florencoenosvites are: а) flood-meadow (Humidopratophytum) – 92 coenoelements (8.02%); b) land-meadow (Mesopratophytum) – 132 coenoelements (10.92%); 3) Meadow-steppe (Prato-Steppophyton) – 164 coenoelements (13.56%); 4) Xerothermic shrub (Xerothamnophyton) – 32 coenoelements (2.65% ); 5) Marsh (Paludophyton) – 31 coenoelements (2.56%); 6) Hygro-hydrophilic (Hyhro-Hydrophyton) – 129 coenoelements (10.67%). As a part of the Hygro-Hydrophyton the florencoenosvites are: a) coastal-water (Hygrophytum) – 79 coenoelements (6.53%); b) aqueous (Hygrophytum) – 50 coenoelements (4.13%); 7) Synanthropic (Synantropophyton) – 285 coenoelements (23.57%). In the composition of the Syntantropophyton the florencenosvites are as follows: a) vegetative vegetation (Segetalophytum) – 132 coenoelements (10.92%) and b) ruderal vegetation (Ruderalophytum) – 153 coenoelements (12.65%). The results of the analysis of the ecological-coenotic structure of the flora of the Transcarpathian plain showed that the leading position is occupied by species of the immoral florenceonotype (Nemoralophyton) (with the predominance of the helio-quercetal florencoenosvita (Quercetophytum); meadow (Pratophyton) (with the predominance of land-meadow florencoenosvita (Mesopratophytum) and meadow-steppe (Prato-Steppophyton) florencoenotypes. The distribution of species by major ecological-coenotic groups reflect the features of the main genetic types of vegetation, climatic, edaphic conditions and terrain of the territory under study

To support invasive alien species risk assessments, the Tracking Invasive Alien Species (TrIAS) project has developed an automated, open, workflow incorporating state-of-the-art species distribution modelling practices to create risk maps using the open source language R. It is based on Global Biodiversity Information Facility (GBIF) data and openly published environmental data layers characterizing climate and land cover. Our workflow requires only a species name and generates an ensemble of machine-learning algorithms (Random Forest, Boosted Regression Trees, K-Nearest Neighbors and AdaBoost) stacked together as a meta-model to produce the final risk map at 1 km2 resolution (Fig. 1). Risk maps are generated automatically for standard Intergovernmental Panel on Climate Change (IPCC) greenhouse gas emission scenarios and are accompanied by maps illustrating the confidence of each individual prediction across space, thus enabling the intuitive visualization and understanding of how the confidence of the model varies across space and scenario (Fig. 2). The effects of sampling bias are accounted for by providing options to: use the sampling effort of the higher taxon the modelled species belongs to (e.g., vascular plants), and to thin species occurrences. use the sampling effort of the higher taxon the modelled species belongs to (e.g., vascular plants), and to thin species occurrences. The risk maps generated by our workflow are defensible and repeatable and provide forecasts of alien species distributions under further climate change scenarios. They can be used to support risk assessments and guide surveillance efforts on alien species in Europe. The detailied modeling framework and code are available on GitHub: https://github.com/trias-project.

<em>Abstract.</em>—The Willamette River is Oregon’s largest river, with a basin area of 29,800 km<sup>2</sup> and a mean annual discharge of 680 m<sup>3</sup>/s. Beginning in the 1890s, the channel was greatly simplified for navigation. By the 1940s, it was polluted by organic wastes, which resulted in low dissolved oxygen concentrations and floating and benthic sludge deposits that hindered salmon migration and boating. Following basin-wide secondary waste treatment and low-flow augmentation, water quality markedly improved, salmon runs returned, and recreational uses increased. However, water pollution remains a problem as do physical habitat alterations, flow modification, and alien species. Fish assemblages in the main-stem Willamette River were sampled systematically, but with different gear, in the summers of 1945, 1983, and 1999. In the past 53 years, tolerant species occurrences decreased and intolerant species occurrences increased. In the past 20 years, alien fishes have expanded their ranges in the river, and four native fish species have been listed as threatened or endangered. We associate these changes with improved water quality between 1945 and 1983, fish migrations, altered flow regimes and physical habitat structure, and more extensive sampling.

Alterations to the inventory of about 24 000 species and infraspecific taxa of bryophytes and vascular plants in southern Africa are reported for the year 1987. The inventory, as presently maintained in the Taxon component of the PRECIS system, contains the accepted name for each taxon, synonyms previously in use as accepted names during the past half-century, and literature references necessary to identify species in each genus and to establish the synonymy. The inventory is updated as new research affecting plant classification in southern Africa is published. During 1987 there were 678 alterations, representing about 2,8% of the total number of taxa.a

The vascular flora of Matokit Mt (Biokovo Massif) in southern Croatia was researched in different vegetation periods from 2010-2015, and a total of 604 vascular plant taxa belonging to 86 families and 337 genera were found. The studied area has never been studied in the past and these are the first detailed floristic data about grasslands in different succession stages of Matokit Mt. Collected herbarium specimens (345 sheets) were digitalized and are available at the ZAGR Virtual Herbarium. The most dominant families were legumes (Fabaceae 9.9%), grasses (Poaceae 9.1%), daisies (Asteraceae 7.4%) and mints (Lamiaceae 6.8%). The analysis of life forms shows the dominance of hemicryptophytes (39.9%) and therophytes (26.2%) on Matokit Mt that indicates a high influence of the Mediterranean climate. A total of 36 endangered and 17 invasive plant taxa across the whole studied area were recorded. Endemic are 32 plant taxa (26 endemics in a broader sense and 6 stenoendemics) and they represent new site of Croatian flora. The occurrence of some very rare endemics (Cardamine fialae Fritsch and Erysimum croaticum Polatschek) in the flora of Matokit Mt is of special interest for the national flora.

Marine Protists

&lt;p&gt;Marine protists are a phylogenetically diverse group of single-celled eukaryotes that respond sensitively to changes in environmental conditions. Yet, our understanding how long-term climate variability has shaped the taxonomic composition is mostly unknown, especially of non-biomineralizing groups, such as green algae, since traditional micropaleontological studies are limited to the analysis of microfossil remains with often hardly discernable morphological differences between species (e.g. diatoms). Here we present a sedimentary ancient DNA (&lt;em&gt;sed&lt;/em&gt;aDNA) record of the marine sediment core SO201-2-12KL, which was retrieved from the eastern continental slope of Kamchatka at 2173 m water depth (N 53.992660&amp;#176;, E 162.375830&amp;#176;) and covers the past 19.9 thousand years. We applied &lt;em&gt;sed&lt;/em&gt;aDNA metabarcoding to 63 samples using a diatom-specific, short plastid marker that is part of the &lt;em&gt;rbcL&lt;/em&gt; gene. Additionally, we used metagenomic shotgun sequencing on a subset of 26 samples to investigate the overall taxonomic composition of protists. Metagenomic shotgun sequencing revealed a variety of unicellular plankton groups mostly from green algae (especially &lt;em&gt;Bathycoccus&lt;/em&gt;) and diatoms. At 11.1 cal kyr BP only single sequences assigned to green algae, diatoms and coccolithophorids could be detected. Metabarcoding showed strong variability in the richness of diatom sequence variants, which was highest during Heinrich Stadial 1 and the Younger Dryas. From about 11.4 cal kyr BP diatom taxonomic diversity strongly decreased until about 10.7 cal kyr BP. This was associated with highest taxonomic and phylogenetic turnover recorded over the past 19.9 cal kyr. Concomitant with this we recorded sequences assigned to &lt;em&gt;Skeletonema&lt;/em&gt; &lt;em&gt;subsalsum&lt;/em&gt;, a coastal diatom associated with low salinities or freshwater. Tentatively, as we wait for the confirmation by further sequencing, we suggest that the reduced protist diversity during the Early Holocene resulted from sea surface freshening, which led to a strengthened vertical stratification which could have reduced past productivity due to limited nutrient supply from deeper waters to the photic zone.&lt;/p&gt;

A study of the taxonomic diversity of diatom algae in Holocene bottom sediments of two small water basins at the western coast of the lake Babinaskaya Imandra (Murmansk Region) has demonstrated the historical transformations of the species compositions of structures of diatom complexes associated with environmental changes in the Holocene. The water basins studied featured the predominance of the benthic and adhesive algae in the algal communities throughout the Holocene. The most drastic changes in the diatom complexes were associated with a tectonic event nearby the Imandra depression.
