    The most serious problem of intergeneric and interspecific hybridization is related to overcoming the reproductive isolation of different species. We assessed the efficiency of reproduction under in vitro conditions and the ex vitro growth capacity of interspecific hybrids of Vaccinium uliginosum (V. corymbosum V. angustifolium). The percentage of seed germination in in vitro culture was 88% for V. uliginosum, form No. 8 (V. corymbosum V. angustifolium), SC5-8, while it was 42% for V. uliginosum, form No. 8 (V. corymbosum V. angustifolium), ‘Northcountry’. The analysis of mean value showed that the multiplication rate increased and the shoot height decreased as the 2-isopentenyl adenine (2iP) concentration was increased in the nutrient medium of the studied hybrids. The maximum rate was achieved using 15 M 2iP. A detailed analysis of the hybrids indicated that the hybrid variant reliably affected growth and development indicators. Inter simple sequence repeat analysis demonstrated that all analyzed hybrids inherited DNA fragments of the parent plants in various combinations, confirming their hybrid nature. Thus, the use of in vitro methods for the propagation and further selection of genotypes is demonstrated as being an effective approach for developing interspecific hybrids of V. uliginosum (V. corymbosum V. angustifolium)

    The abstract presents the initiative to develop the Fungal Literature-based Occurrence Database for Southern West Siberia (FuSWS), which mobilizes occurrences of fungi from published literature (literature-based occurrences, Darwin Core MaterialCitation). The FuSWS database includes 28 fields describing species name, publication source, herbarium number (if exists), date of sampling or observation, locality information, vegetation, substrate, and others. The initiative on digitization of literature-based occurrence data started in the northern part of Western Siberia two years ago (Filippova et al. 2021a). The present project extends the initiative to the south and includes eight administrative regions (Sverdlovsk, Omsk, Kurgan, Tomsk, Novosibirsk, Kemerovo, Altay, and Gorny Altay). The area occupies the central to southern part of the West Siberian Plain. It extends for about 1.5 thousand km from the west to the east from the eastern slopes of the Ural Mountains to Yenisey River, and from north to south—about 1.3 thousand km. The total area equals about 1.2 million km2.Currently, the project is actively growing in spatial, collaboration and data accumulation terms. The working group of about 30 mycologists from 16 organizations dedicated to the digitization initiative was created as part of the Siberian Mycological Society (informal organization since 2019). They have created the most complete bibliographic list of mycology-related papers for the Southern West Siberia, including over 800 publications for the last two centuries (the earliest dated 1800). At abstract submission, the database had been populated with a total of about 10K records from about 100 sources. The dataset is uploaded to GBIF, where it is available for online search of species occurrences and/or download (Filippova et al. 2021b) Fig. 1. The project's page with the introduction, templates, bibliography list, video-presentations and written instructions is available at the website of the Siberian Mycological Society (https://sibmyco.org/literaturedatabase).The following protocol describes the digitization workflow in detail:The bibliography of related publications is compiled using Zotero bibliographic manager. Only published works (peer-reviewed papers, conference proceedings, PhD theses, monographs or book chapters) are selected. If possible, the sources are digitized and added to the library as PDF files. The template of the FuSWS database is made with Google Sheets, which allows simultaneous use by several specialists, in a common data format provided. The simple Microsoft Excel template is also available for the offline databasing. The Darwin Core standard is applied to the database field structure to accommodate the relevant information extracted from the publications.From the available bibliography of publications related to the region, only works with species occurrences are selected for the databasing purpose. The main source of occurrences is annotated species lists with exact localities of the records. However, different sorts of other species citations are also extracted, provided that they had the connection to any geography. All occurrences are georeferenced, either from the coordinates provided in the paper, or from the verbatim description of the field work locality. The georeferencing of the verbatim descriptions is made using Yandex or Google map services. Depending on the quality of georeference provided in publications, the uncertainty is estimated as follows: 1) the coordinate of a fruiting structure or a plot provided in the publication gives the uncertainty about 3-30 meters; 2) the coordinate of the field work locality provided in publication gives the uncertainty about 500 m to 5 km; 3) the report of the species presence in a particular region gives the centroid of the area with the uncertainty radius to include its borders.The locality names reported in Russian are translated to English and written in the «locality» field. Russian descriptions are reserved in the field «verbatimLocality» for accuracy.When possible, the «eventDate» is extracted from the annotation data. Whenever this information is absent, the date of the publication is used instead with the remarks in the «verbatimEventDate» field.The ecological features, habitat and substrate preferences are written in the «habitat» field and reserved in Russian.The original scientific names reported in publications are filled in the «originalNameUsage» field. Correction of spelling errors is made using the GBIF Species Matching tool. This tool is also used to create the additional fields of taxonomic hierarchy from species to kingdom, to fill in the «taxonRank» field and to synonymize according to the GBIF Backbone Taxonomy.To track the digitization process, a worksheet is maintained. Each bibliographic record has a series of fields to describe the digitization process and its results: the total number of extracted occurrence records, general description of the occurrence quality, presence of the observation date, details of georeferencing and the name of a person responsible for the digitization

    The paper presents the initiative on literature-based occurrence data mobilisation of fungi and fungi-related organisms (literature-based occurrences, Darwin Core MaterialCitation) to develop the Fungal literature-based occurrence database for the southern West Siberia (FuSWS). The initiative on mobilisation of literature-based occurrence data started in the northern part of West Siberia in 2016. The present project extends the initiative to the southern regions and includes ten administrative territories (Tyumen Region, Sverdlovsk Region, Chelyabinsk Region, Omsk Region, Kurgan Region, Tomsk Region, Novosibirsk Region, Kemerovo Region, Altai Territory and Republic of Altai). The area occupies the central to southern part of the West Siberian Plain and extends for about 1.5 K km from the west to the east from the eastern slopes of the Ural Mountains to Yenisey River and from north to south—about 1.3 K km. The total area equals about 1.4 million km . The initiative is actively growing in spatial, collaboration and data accumulation terms. The working group of about 30 mycologists from eight organisations dedicated to the data mobilisation was created as part of the Siberian Mycological Society (informal organisation since 2019). They have compiled the almost complete bibliographic list of mycology-related papers for the southern West Siberia, including over 900 publications for the last two centuries (the earliest dated 1800). All literature sources were digitised and an online library was created to integrate bibliography metadata and digitised papers using Zotero bibliography manager. The analysis of published sources showed that about two-thirds of works contain occurrences of fungi for the scope of mobilisation. At the time of the paper submission, the database had been populated with a total of about 8 K records from 93 sources. The dataset is uploaded to GBIF, where it is available for online search of species occurrences and/or download. The project's page with the introduction, templates, bibliography list, video-presentations and written instructions is available (in Russian) at the web site of the Siberian Mycological Society. The initiative will be continued in the following years to extract the records from all published sources. New information The paper presents the first project with the aim of literature-based occurrence data mobilisation of fungi and fungi-related organisms in the southern West Siberia. The full bibliography and a digital library of all regional mycological publications created for the first time includes about 900 published works. By the time of paper submission, nearly 8 K occurrence records were extracted from about 90 literature sources and integrated into the FuSWS database published in GBIF

    Climate, host and geography shape insect and fungal communities of trees

    13 Pág.Non-native pests, climate change, and their interactions are likely to alter relationships between trees and tree-associated organisms with consequences for forest health. To understand and predict such changes, factors structuring tree-associated communities need to be determined. Here, we analysed the data consisting of records of insects and fungi collected from dormant twigs from 155 tree species at 51 botanical gardens or arboreta in 32 countries. Generalized dissimilarity models revealed similar relative importance of studied climatic, host-related and geographic factors on differences in tree-associated communities. Mean annual temperature, phylogenetic distance between hosts and geographic distance between locations were the major drivers of dissimilarities. The increasing importance of high temperatures on differences in studied communities indicate that climate change could affect tree-associated organisms directly and indirectly through host range shifts. Insect and fungal communities were more similar between closely related vs. distant hosts suggesting that host range shifts may facilitate the emergence of new pests. Moreover, dissimilarities among tree-associated communities increased with geographic distance indicating that human-mediated transport may serve as a pathway of the introductions of new pests. The results of this study highlight the need to limit the establishment of tree pests and increase the resilience of forest ecosystems to changes in climate.We gratefully acknowledge the financial support of the Swiss National Science Foundation (Project C15.0081) Grant 174644 and the Swiss Federal Office for the Environment Grant 00.0418.PZ/P193-1077.

    No full text
    A new species, Nitraria iliensis sp. nov., is described from the Ili basin, Almaty region, Kazakhstan. It belongs to section Nitraria ser. Sibiricae and is morphologically similar to N. sibirica Pall. An integrative taxonomic approach based on molecular, biochemical and morphological analyses, along with palynological data, was used to delimit this new species. The studied species of the genus are illustrated, and photographs of authentic specimens of the new species, as well as a distribution map of the new species and segregate taxa, are provided. Morphological characters were investigated, more important traits for identification were found, and a new key to distinguish between all species of the genus was prepared
