Trans-species relation in communities of pathogenic Polyporaceae on pedunculate oak Quercus robur L

In the process of research phytopathological and mycocenological methods were used As a result of the research, real trans-species relation were revealed in the most common and frequently occurring types of PPF on oak within various communities: Mutually positive type relationships based on the proto-operation were found between Laetiporus sulphureus and Fistulina hepatica. Neutral type relationships were found in between Fistulina hepatica and Fomitiporia robusta, Laetiporus sulphureus and Fomitiporia robust

Opportunities for the analysis of the spatial ecological structure of the mycobiota of macromycetes of a natural-territorial entity (the case of the Botanical Garden of Belgorod University, Belgorod, Russia)

On the basis of direct observations, the general principles of the organization of the mycobiota of the macromycetes of the natural-territorial formation "Botanical Garden" of Belgorod State University (Belgorod, Russian Federation) have been clarified. Based on the clarified principles, a scheme of their spatial ecological organization has been constructed: mycobiota - mycohore (mycocenosis, mycoaggregation) - mycosinium-3 - mycocenocells - mycocell. The obtained results can be used to study the spatial ecological organization of mycobiota macromycetes of other natural-territorial formation

HIERARCHICAL STRUCTURE OF PATHOGENIC POLYPORE FUNGI COMMUNITY ON PEDUNCULATE OAK IN THE OAK FORESTS OF THE SOUTHWEST OF THE CENTRAL RUSSIAN UPLAND

The article deals with the possibilities of typological classification and hierarchical subordination of the communities of pathogenic polypore fungi Polyporaceae s. l., associated with Pedunculate oak Quercus robur L. They allow to propose a schematic-model of the hierarchical structure of the regional community of pathogenic polypore fungi on Pedunculate oak (communities of pathogenic polypore fungi on Pedunculate oak) in the oak forests of the southwest of the Central Russian Upland. Based on studies, conducted in the oak forests of the Belgorod, Shebekinsky, Korochansky, Borisovsky administrative districts of the Belgorod region of the Russian Federation and the territory of Belgorod, 6 types of elementary PQ-mycopathocenosis were distinguished: four types of full-membered and two types of semicomplete. Two groups of types of elementary PQ-mycopathocenosis have been identified. Four-level scheme-model of the hierarchical structure of the regional community of pathogenic polypore fungi was proposed. It allowed not only to systematize information about this community of wooddestroying fungi, taking an active part in modern succession processes, occurring in the oak forests of the foreststeppe, but also to create prognostic models for their formation under different conditions. Keywords: hierarchical structure, community, cenosis, Pathogenic Polypore Fungi on Pedunculate oak, PPF on oak, PPF, PQ -mycopathocenosis, type of PQ -mycopathocenosis, subordination level

New trophic classification of wood-destroying fungi the case of community of pathogenic polypore fungi types on Pedunculate oak

Based on the generalization of experimental data obtained during the practical study of the trophic specialization of wood-destroying fungi from the commonness of PTH on oak in the oak forests of the south-west of the Central Russian Upland, a new ecotrophic classification has been developed, including the following groups of wood-destroying fungi: biotrophic pathogens, saprotrophic pathogens, pathogenic saprotrophs, non-pathogenic saprotroph

Cryopreservation of raspberry cultivar accessions bred in Russia from the VIR <i>in vitro</i> collection

Cryobanks use plant cryocollections for long-term preservation of crops which cannot be preserved in seed collections. These are vegetatively propagated crops, accessions of species which form either a small amount of seeds, or recalcitrant seeds. Shoot tips (apexes) of in vitro plants are used for cryopreservation for most berry crops, therefore maintenance of in vitro collections is very important. The VIR in vitro collection includes 150 accessions of Rubus L. species, 85 of them are raspberry cultivars, 59 of which were bred in Russia. These cultivars reflect a wide ecogeographic diversity. Among them, there are raspberry cultivars created at the end of the 19th – first half of the 20th centuries, including cultivars bred by I.V. Michurin and by the pioneer of northern horticulture V.V. Spirin. More than half of national raspberry varieties (33) are listed in the State Register for Selection Achievements Admitted for Usage. Raspberry cultivars from Russian breeding programs have a very limited representation in foreign genebanks. The first aim of the present work was cryopreservation of mostly folk and old Russian raspberry cultivars received by VIR from 1925 till 1950 and their transfer into the cryobank. The second aim of the work was to monitor post-cryogenic regeneration of raspberry cultivars transferred to the cryobank earlier. A modified protocol of the droplet vitrification method by “DV-biotech” was used for cryopreservation of shoot tips of in vitro plants of 10 raspberry cultivars (7 of which are folk and old Russian ones) from the VIR in vitro collection. Post-cryogenic regeneration was evaluated for 17 raspberry cultivars preserved in the cryobank from one to five years. Ten raspberry cultivars (900 apexes) with an average mean post-cryoregenic regeneration value of 38.2±3.0% determined in control tests, were placed in the cryobank for long-term storage. A statistically significant effect of the genotype on the viability of explants after cryopreservation was noted, while the post-cryogenic regeneration was genotype insensitive. Additionally, levels of post-cryogenic regeneration were evaluated for 17 raspberry cultivars (296 apexes) preserved in the cryobank from one to five years. Post-cryogenic regeneration within the 20-70% range was displayed by four raspberry cultivars preserved in the cryobank for one year, and for 8 cultivars conserved there from three to five years post-cryogenic regeneration was within the 10-50% range. According to the results of monitoring, regeneration displayed by 12 raspberry cultivars was within the 10-70% range, which can be considered as a reliable rate of apex preservation in liquid nitrogen vapors in the VIR cryobank. Monitoring of the post-cryogenic regeneration of the raspberry accessions preserved in the VIR cryobank and cryopreservation of new raspberry cultivars will be continued

Электронно-библиотечная система как средство саморазвития студентов цифрового поколения Z (на примере изучения курса «Основы вожатской деятельности»)

The digital library system of universities is examined by the example of the learning course “The basic knowledge for summer camp leaders”. The theory of generations, socio-psycological characteristics of learning styles, and corresponding pedagogical methods and technologies in education and library and information services provided to the generation Z users, are discussed. The generation’s characteristics are: hypermobility, creativity and mental quickness, realistic attitude, rapid moving into adulthood, and the fact that they are not enthusiastic about hand writing. At the same time, the young adults are characterized by clip way of thinking, lack of motivation, laziness, no love for reading, communication through mems and emojies, low tolerance and responsibility. Within the digital information environment, the generation Z processes clip information in no time and, hence, they are not able to act thoughtfully, to concentrate and to analyze facts. These characteristics are admitted by psychologists, physiologists, sociologists, and pedagogues. New teaching methods and technologies have to be designed, learning and recreational information content based on digital convergent approach to be generated. The significance of cooperation and interaction between professionals in the education, information and library spheres is emphasized. The study is accomplished within teaching the optional course “The basic knowledge for summer camp leaders”.Рассмотрена электронно-библиотечная система в вузе на примере использования учебного курса «Основы вожатской деятельности». Представлена теория поколений, обозначены социально-психологические особенности восприятия поколения Z и обусловленные ими педагогические методы и технологии, применяемые в образовательном процессе и библиотечно-информационном обслуживании представителей этого поколения. Выделены их отличительные черты: гиперподвижность, креативность и живость мышления, трезвое представление о жизни, быстрое взросление, они не пишут от руки. Вместе с тем им свойственны так называемая клиповость восприятия, отсутствие мотивации, лень, нелюбовь к чтению, общение с помощью мемов и эмоджи, плохо развитые терпеливость и чувство долга. Постоянно находясь в информационно-цифровой среде, поколение Z научилось быстро обрабатывать «клиповую» информацию, вследствие чего его представителям не свойственны вдумчивость, способность сосредоточиваться, анализировать факты. Эти особенности поколения Z признаны психологами, физиологами, социологами, педагогами. Поэтому необходимо разрабатывать новые методы и технологии обучения, создавать информационно-образовательный и информационно-рекреационный контент, основанный на электронно-конвергентном подходе. Подчёркнута важность сотрудничества и взаимодействия специалистов в области образования, информатики и библиотечного дела. Исследование проведено в процессе преподавания курса по выбору «Основы вожатской деятельности»
