Lichtverfügbarkeit, Baumwachstum und Nachhaltigkeit im Dauerwald auf Buchenstandorten
Authors: Brüllhardt Martin , Rotach Peter , Bugmann Harald
Published: October 2022

Die Lichtverfügbarkeit prägt die Verjüngungsdynamik in Wäldern auf Böden mit guter Wasser- und Nährstoffversorgung wesentlich. In der Dauerwaldbewirtschaftung wird die Verjüngung unter dem Schirm der Altbäume eingeleitet. In der Regel bleibt die Beschattung über einen längeren Zeitraum erhalten. Um die Wachstumsmuster unter diesen Verhältnissen auf Buchenstandorten hinsichtlich der Mischungsmöglichkeiten im Dauerwald besser zu quantifizieren, wurden Buchen (Fagus sylvatica L.) und Bergahorne (Acer pseudoplatanus L.) der Dickungs- und Stangenholzklasse für das vorliegende Forschungsprojekt einer Stammscheibenanalyse unterzogen. Während sowohl Höhen- wie Durchmesserentwicklung beider Baumarten stark von der Lichtverfügbarkeit abhingen, hat sich gezeigt, dass der Höhenzuwachs der Buche bei Dichtstand grösser ist. Der Bergahorn profitierte von einer längeren Krone, die pflegerisch ausgebaut werden sollte, zeigte aber bereits bei kleinem Durchmesser mit zunehmendem Alter verringerte Höhenzuwächse. Im demografischen Gleichgewicht, das im Buchendauerwald bei einer Grundfläche von 21 bis 25 m2 liegt, ist daher vor allem in kleinen Lücken (<270 m2) bei weniger als 10% der Freiland-Lichtverfügbarkeit der Aufwuchs des Bergahorns in die Kronenschicht stark infrage gestellt. Unter diesen Verhältnissen ist sein Anteil in der Verjüngung kleiner als 25%, und die Durchwuchszeit durch die ersten beiden Brusthöhendurchmesser-Klassen (1–8 cm BHD) beträgt durchschnittlich 51 Jahre. Um ein demografisches Gleichgewicht zu erhalten, sind in der BHD-Klasse 8–12 cm pro Hektare 90–120 Bäume anzustreben. Damit auch wesentliche Anteile von Bergahorn in der Mischung sichergestellt werden können, sollte dieser in Lücken von mindestens 400 m2 verjüngt werden. Durch räumlich heterogene Eingriffe und gruppenweise Entnahmen kann im Dauerwald ein vielfältiges Mosaik an Verjüngungsnischen geschaffen werden. Dadurch entstehen Möglichkeiten für den Erhalt oder die Schaffung von Baumartenmischungen.

Published: October 2022

Kindergärten und Schulen nutzen die Schweizer Wälder vermehrt als Klassenzimmer. Die pädagogische und sozialwissenschaftliche Forschung beschäftigt sich seit vielen Jahren intensiv mit den Auswirkungen des Waldunterrichts auf die persönliche und schulische Entwicklung der Kinder. Es fehlt aber an Forschung und Literatur, die den Einfluss dieser Waldnutzung auf die Vegetation des Waldes und den Erhalt sowie die Entwicklung der Bäume im Bestand untersucht. Im Rahmen einer Bachelorarbeit wurde diese Thematik mittels Feldaufnahmen und Interviews analysiert. Fazit: Der Waldunterricht sollte immer an den gleichen Stellen durchgeführt werden, um negative Einflüsse auf den Wald zu minimieren. Zudem sollten Synergien zwischen den einzelnen pädagogischen Angeboten besser genutzt werden.

A User Location Prediction Method Based on Similar Living Patterns
Authors: Hu Jiali , Chen Hongmei , Xiao Qing
Published: October 2022

With the development of fifth-generation mobile communication technology, a huge volume of mobile data have been generated which enable a wide range of location-based services. As a result, user location prediction has attracted attention from researchers. However, existing methods have low accuracy due to the sparsity of user check-ins. In order to address this issue, we propose a method for user location prediction based on similar living patterns. We first obtain a vector representation of each user’s living habits to cluster users with similar living patterns. Then, embedded vectors of POI category and POI location are learned. Finally, we construct activity prediction model and location prediction model for each user cluster by using Gate Recurrent Unit (GRU). The experimental results for real user check-ins show that the proposed method outperforms the baseline methods in most cases.

Affective Analysis and Visualization from Posted Text, Replies, and Images for Analysis of Buzz Factors
Authors: Amitani Reishi , Matsumoto Kazuyuki , Yoshida Minoru , Kita Kenji
Published: October 2022

In this study, we propose a method to visualize the factors that contribute to the buzz phenomenon triggered by Twitter posts. The analysis included tweets, images, and replies. Replies are after-the-fact responses posted in response to a posted tweet and therefore cannot be used to predict buzz phenomena. Therefore, they cannot be used to predict the buzz phenomena. In this study, the tweet body, images, and reply text were feature vectors, and an affective analysis model was constructed. Visualization of the relationship between the sensibility features output from this model and the number of RTs and likes (echo index), which represent the scale of the buzz, will be useful for analyzing the factors behind the popularity. Consequently, the subjective sensibility information with the most likes also tended to have a higher degree of similarity among the sensibility vectors.

Published: October 2022

The main problems of the traditional perceptron learning algorithm (PLA) is that there are too many iterations and it is difficult to generate a model quickly, and more iterations are needed when the boundary between the two classes is closed. In this paper, we improve PLA by introducing the current weight into the updating formulation, which can significantly accelerate the iteration. The experiments on different public datasets show that our proposed method can greatly improve the speed of the traditional PLA.

Authors: Lezin Mihail , Lezina Vera
Published: October 2022

Abstract. The purpose of this scientific study is the production testing of apricot varieties of different origin away from industrial areas and settlements that can have a softening effect on temperature decrease to critical values for culture and the identification of abiotic factors affecting the productivity and regularity of fruiting of apricot varieties of different origin. The study was conducted according to the classical methods of the state strain testing of fruit crops. The planting scheme is 3 × 5 m, the rootstock is sand cherry (Prunus pumila L.). Results and practical significance. The apricot varieties most adapted to specific soil and climatic conditions, capable of bearing fruit 4–5 years out of 7 to varying degrees, have been identified. It has been established that frosts during flowering and ovary growth have the greatest effect on productivity and regularity of fruiting. To the greatest extent, it was possible to unlock the potential of productivity only in the year when frosts on flowering and ovaries did not reach the critical mark of –3 °C. In adapted varieties, the death of flower buds in winter was observed only 1 time in 9 years due to recurrent frosts after thaws. The delay in the beginning of flowering by 2–4 days provided a higher yield for late-flowering varieties in 1 accounting year. The self-fertility of the variety provided an additional 1 year to a yield. Scientific novelty. For the first time in the conditions of the Urals and Siberia, the sensitivity of apricot culture to abiotic factors in production conditions far from industrial and residential areas was demonstrated based on the materials of the state competitive strain testing.

The purpose of the study was to establish the productivity and grain quality of winter bread wheat sown after sunflower, when using nitrogen additional fertilizing. Ammophos and ammonium sulfate were applied under seedbed cultivation; ammonium nitrate, urea and carbamide-ammonia mixture were used as additional fertilizing at different periods of active winter wheat vegetation. Methods. The research was conducted at the Agricultural Research Center “Donskoy” in 2017–2019. When laying and conducting the experiment, taking into account the yield, generally accepted methods were used; the technology of winter wheat cultivation and the dose of nitrogen fertilizing corresponds to the Zonal farming systems of the Rostov region. Scientific novelty. For the first time there have been determined the best terms, methods and doses of nitrogen additional fertilizing with various types of fertilizers for winter bread wheat in the southern part of the Rostov region. Results. There was established a significant effect of the terms of nitrogen fertilizing on productivity, as well as on winter wheat quality. Portioned application of ammonium nitrate at a dose of N90 contributed to obtaining the maximum productivity of 6.15 t/ha in the trial, and productivity increase in comparison with the control variant was 2.34 t/ha or 61.4%. In other variants of the trial, productivity increase due to the use of nitrogen fertilizers ranged from 0.90 to 2.26 t/ha. Autumn application of ammonium sulfate at a dose of N30 under seedbed cultivation was an effective agricultural method that contributed to an additional productivity improvement on 0.55–0.64 t/ha. The high efficiency of nitrogen additional fertilizing was due to an improvement of the indicators of yield structure elements, namely, ‘kernel weight per head’ and ‘number of productive stems’. Nitrogen additional fertilizing improved qualitative characteristics of the product. There has been found out that under a portioned application of ammonium nitrate at a dose of N90, there were yielded the highest economic indicators, such as 30117 rubles/ha of conditional net income and 112.9 % of production profitability.

Abstract. The purpose of the research is to develop a comprehensive assessment system with new indicators of feed behavior and feed conversion in Duroc pigs based on a selection index. Research methods. The Herdsman database was used, which includes the processing of data on fattening characteristics and feeding behavior of 764 heads of Duroc pigs that have passed test fattening at automatic feeding stations. 13 indicators were evaluated, of which 7 indicators of feeding behavior and 6 – fattening characteristics. The evaluation of breeding value animals according to studied traits was carried out using the BLUP Animal Model methodology. Results. When determining the weight coefficients of final index equation, which included all the studied traits, we relied on the chosen principle, according to which 50 % was given to weight coefficients of feeding behavior traits and 50 % to the weights of the fattening indicators. Also, in accordance with this principle, in feeding behavior indicators, 25 % was allocated for feed conversion, and the same amount in fattening indicators – for the average daily weight gain. The obtained values of the coefficients presented the general structure of the selection index: Itotal = 0.5I1 + 0.5I2 = 0.0241 (TPD) + 0.0439 (ADFI) – 0.0376 (NVD) – 0.0322 (TPV) – 0.0074 (FR) + 0.0376 (FPV) – 0.5343 (FCR) + 0.0531 (Age1) + 0.0778 (Age0) + 0.1217 (BW1) + 0.1027 (BW0) + 0.0331 (BWG) + 0.4557 (ADG). The results obtained showed the difference between the minimum and maximum index, which was 76 sigma points. Also, according to distribution according the categories of RBV (relative breeding value) among 14 pigs with an index greater than 120 units, 30.8 % have the category “unconditional improver” and 25.8 % – the category “improver”. Scientific novelty. These results show the direct impact of feeding behavior and feed conversion on the refinement of animal’s genetic potential, which will improve the system of selection and genomic evaluation of animals.

Abstract. Pig breeding is inevitably accompanied by an attack on animals by a large number of flies. Effective fly control requires biological information about the dynamics of the fly population over the seasons. The aim of the study was to determine the number and species composition of flies in the conditions of the Khatas pig farm in the winter. Methods. In the Khatas pig farm, during the technological cycle of production in December 2021, studies were carried out to determine the number of flies. To count the number of flies in the pigsties of the breeding, reproduction and fattening shops, traps were installed in the form of sticky tapes 84 cm long. There were 15 pigsties in three workshops of the pig farm. In each pigsty, one trap was placed at a height of 1.5 m from the floor. The number of insects caught on the glue trap was counted after 24 hours under laboratory conditions. Data analysis was carried out according to the method of V. N. Beklemishev. A trap with an exposure of 24 hours was taken as the unit for counting the number of flies. Results. For the first time, research has established the spread of flies in winter during the technological cycle of production at Khatas pig farm LLC. During the day, 1102 flies were caught by traps in three workshops. The species composition of flies in winter was represented by one species of Musca domestica L .The abundance index of adult flies in the rearing shop was 30.25 ± 7.56 flies per trap-day, and in the reproduction and fattening shops – 34 ± 5.78, and 57.2 ± 8.55 flies per trap-day, respectively. The scientific novelty lies in the fact that the number of adults of flies and their species composition in the Khatas pig farm of Yakutia in the winter period were determined for the first time in the obtained materials.
Multilocus genetic analysis of two-breed chicken hybrids
Authors: Tyschenko Valentina
Published: October 2022

Abstract. Background. Due to the fact that now many new forms of poultry are created by crossing existing breeds and populations, a comprehensive genetic analysis of hybrid chickens as a ground for further breeding work is of particular importance. Aim. To study the features of the population and genetic organization of the genomes of inter-breed chicken hybrids. Materials and methodology. The experimental work was based on the use of an oligonucleotide probe (GTG)5, which was labeled with digoxygenin. The probe was hybridized with genomic DNA on a nylon filter, and then labeled DNA fragments were visualized using a streptavidin-alkaline phosphatase conjugate chemistry. The number and distribution of DNA fragments was highly specific for each individual. These parameters under study include similarity coefficient (BS), genetic distances between groups (D) and average heterozygosity levels (H). Scientific novelty. For the first time, marker DNA fragments characterizing individual groups of birds have been identified; these fragments can be used in the certification of populations. The novelty of the work also lies in the determination of the main genetic characteristics in new groups of hybrid chickens, which will be used to consolidate the desired breeding traits. Results. Based on the data obtained, it can be concluded that there are relatively small genetic differences between various hybrid forms, which is the result of using the same source breeds. Brahma × Sussex Light and Uzbek Game × Amrock hybrids were relatively distant from each other (D = 0.070). Sussex Light× Amrock hybrids were the most genetically diverse according to the criterion of average heterozygosity (P = 0.66).
