Лесная опытная дача Российского государственного аграрного университета - МСХА имени К.А. Тимирязева является неотъемлемой частью становления и развития экспериментального лесоводства в России. Первые работы по изучению лесных насаждений начались здесь в 1862 г. В 2022 г. исполняется 160 лет со времени первого обустройства лесного массива и закладки первых постоянных пробных площадей, поэтому цель исследования - подведение основных итогов научно-исследовательских работ в Лесной опытной даче РГАУ - МСХА за 160 лет непрерывных наблюдений (1862-2022 гг.). С 1862 г. на опытной даче было заложено 258 постоянных пробных площадей в сосновых, лиственничных, березовых, дубовых и еловых насаждениях. Здесь проведены исследования по изучению роста чистых и смешанных древостоев, эффективности лесохозяйственных мероприятий и др., а также проанализирована гидрологическая роль лесных насаждений, их воздействие на перераспределение атмосферных осадков, поверхностный сток и испаряемость. Результаты исследований нашли отражение в научных работах лесоводов, почвоведов, экологов, ботаников, географов и специалистов других естественно-научных направлений. Насаждения Лесной опытной дачи имеют бесценное научное и производственное значение, позволяют формировать теоретические обобщения и разрабатывать практические рекомендации производству, проверенные временем.
Forest Experimental Station of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy is connected with the formation and development of experimental forestry in Russia. The first work on the study of forest stands began here in 1862. 2022 marks another anniversary since the first arrangement of the forest area and the laying of the first permanent trial plots, so the purpose of the study is to sum up the main results of research work in the Forest Experimental Station of the RSAU-MTAA for 160 years of continuous observations (1862-2022). Since 1862, 258 permanent trial plots in pine, larch, birch, oak and spruce stands have been established in the Forest Experimental Station. The results of studying the growth of pure and mixed forest stands, the effect of fertilization, economic activities, the origin of seeds on the dynamics of forest stands were obtained. Studies of the hydrological role of forest stands have been carried out, showing their influence on the redistribution of atmospheric precipitation, water runoff and evaporation. In addition, the results of research are reflected in the scientific work of foresters, soil scientists, ecologists, botanists, geographers and specialists in other natural sciences. The stands of the Forest Experimental Station are of inestimable scientific and industrial importance, they allow making theoretical generalizations and developing time-tested practical recommendations for production.

Рассматривается влияние копытных животных на состояние дубовых культур, созданных на вырубках в нагорных дубравах зоны лесостепи. В культурах разных лет создания проанализированы повреждения двух типов - погрызы стволов деревьев и объедание крон косулями и лосями. Анализ повреждений показал, что одновременное использование лесохозяйственными и охотничьими организациями лесных территорий с участками дубовых культур разного возраста приводит к их массовому повреждению вплоть до полного уничтожения. В регионах естественного ареала произрастания дуба черешчатого в зоне лесостепи предлагается исключить многоцелевое использование лесных участков, так как это создает угрозу уничтожения ценных искусственно созданных дубовых насаждений.
The article examines the influence of ungulates on the state of oak crops created on the cutting down of ripe and overgrown forests of upland oak forests in the forest-steppe zone. In cultures of different years of creation, two types of damage were analyzed - gnawing of tree trunks and overeating of crowns by roe deer and moose. Damage analysis showed that when forestry and hunting organizations simultaneously use forest territories with oak crop plots of oak cultures of different ages, their massive damage was revealed up to complete destruction by ungulates. In the regions of the natural range of the growth of the petiolate oak in the forest-steppe zone, it is proposed to exclude the multipurpose use of forest plots. Multi-purpose use poses a threat of destruction of artificially created valuable oak plantations.

Рассматриваются новые возможности применения авиации для охраны лесов от пожаров. Предложены варианты оптимизации обнаружения и тушения лесных пожаров, возникающих на заданном участке земель лесного фонда, в рамках методологии интегрированных авиационных систем, в качестве целевой функции которых выбраны суммарные потери/затраты государства. Целевая функция вводится с учетом разработанной упрощенной модели распространения и тушения лесного пожара. Проведено сравнение различных парков пожарных воздушных судов: существующих Ил-76, Бе-200, Ка-32, а также перспективных с гипотетическими характеристиками. Показано, что в рамках введенных моделей наиболее рациональным обликом интегрированной авиационной системы тушения лесных пожаров с применением авиационных пожарных танкеров является разделение земель лесного фонда на зоны ответственности отдельных подразделений, в состав которых входит авиапарк на основе беспилотных летательных аппаратов двух типов: малых патрульных и более крупных дежурных. Несмотря на то что проведенное моделирование носит качественный характер, применение подхода интегрированных авиационных систем для задач пожарной авиации позволяет сформировать обоснованные выводы о перспективных направлениях ее развития.
New possibilities of using aviation to protect forests from fires are being considered. Variants of optimization of detection and extinguishing of forest fires arising on a given plot of forest fund lands are proposed within the framework of the methodology of integrated aviation systems, the total losses/costs of the state are selected as the target function of which. The target function is introduced taking into account the developed simplified model of spreading and extinguishing a forest fire. The comparison of various fleets of fire-fighting aircraft is carried out: existing Il-76, Be-200, Ka-32, as well as promising aircraft with hypothetical characteristics. It is shown that within the framework of the introduced models, the most rational appearance of an integrated aviation system for extinguishing forest fires using aviation fire tankers is the division of forest lands into areas of responsibility of individual units, which include an air fleet based on two types of unmanned aerial vehicles: small patrol and larger duty firefighters. Despite the fact that the conducted modeling is of a qualitative nature, the application of the integrated aviation systems approach for fire aviation tasks allows us to form reasonable conclusions about the promising directions of its development.

Проанализировано генетическое разнообразие и структура 5 популяций сосны обыкновенной (Pinus sylvestris L.) из северной части Республики Карелии с использованием 13 микросателлитных локусов. Установлено высокое аллельное разнообразие популяции сосны обыкновенной на исследованных участках, несмотря на то что по степени равномерности распределения аллельных вариантов внутри выборок все исследуемые популяции достаточно однородны. Результат AMOVA-анализа показал относительно невысокий уровень межпопуляционной дифференциации: внутрипопуляционная изменчивость составляет 93 %, а межпопуляционная – 7 %. По результатам кластерного анализа, проведённого на основе матрицы генетических расстояний М. Неи, установлена популяционная структура P. sylvestris в северной части Карелии. Все изученные популяции подразделены на две большие группы.
In this study, we assessed the genetic diversity and population structure of Scotch pine (Pinus sylvestris L.) using 13 microsatellite loci in 5 populations from the northern part of the Republic of Karelia. Our analysis showed a high allelic diversity of the Scots pine population in the studied areas. Although, in terms of the degree of uniformity of the distribution of allelic variants within the samples, all the studied populations are quite homogeneous. The result of the AMOVA analysis showed a relatively low level of interpopulation differentiation, within the population the variability is 93 %, and the interpopulation share of variability is 7 %. According to the results of cluster analysis carried out on the basis of the matrix of genetic distances by M. Nei, we revealed the population structure of P. sylvestris in the northern part of Karelia. All studied populations were divided into two large groups.

Приведены результаты исследования влияния ростовых пудр, содержащих индолил-3-масляную кислоту (ИМК) в разных концентрациях, на корнеобразование у полуодревесневших черенков можжевельника Пфитцера ‘Pfitzeriana Glauca’ (Juniperus × pfitzeriana ‘Pfitzeriana Glauca’). Черенки заготавливали с 8-летних маточных растений в фазе окончания вынужденного зимнего покоя. Показано стимулирующее влияние ростовых пудр с концентрацией ИМК 2,5 г/кг на укоренение черенков данного сорта, что заключалось в повышении укоренямости в 2,0–2,19 раза и значительном улучшении качества корневой системы. С увеличением содержания ИМК в ростовых пудрах от 2,5 до 20 г/кг происходило усиление фитотоксичности регуляторов роста и снижение укореняемости черенков.
The results of a study of the effect of growth powders containing indolyl-3-butyric acid (IBA) in various concentrations on root formation in semi-hardwood cuttings of Juniperus × Pfitzeriana ‘Pfitzeriana Glauca’ are presented. Cuttings were harvested from eight-year-old mother plants at the end of forced winter dormancy. A stimulating effect on the rooting of cuttings of this variety of growth powders with a concentration of IBA of 2.5 g/kg was shown, which consisted in an increase in the percentage of rooting of cuttings by 2.0–2.19 times and a significant improvement in the quality of the root system. With an increase in the concentration of IBA in growth powders from 2.5 g/kg to 20 g/kg, there was a decrease in the percentage of survival and an increase in signs of phytotoxicity of the growth regulators on cuttings.
Challenges of Eco-physiological Interpretation of the Climatic Signal in Dendrochronological and Dendroisotope Time Series
Authors: Чуракова О.В. , Румянцев Д.Е. 
Published: July 2024

Важной проблемой современной дендроклиматологии является интерпретация выявленных статистически достоверных связей между изменчивостью метеорологических переменных (среднемесячная и дневная температура воздуха, ежемесячные суммы осадков текущего и предшествовавшего формированию годичного кольца календарного года) и вариацией дендрохронологических параметров (ширина годичного кольца, максимальная плотность поздней древесины, анатомические характеристики годичного кольца и композиционный состав стабильных изотопов в кольце). Адекватная интерпретация необходима, чтобы понимать, какие экофизиологические механизмы определяют выявленные статистические связи, какую смысловую нагрузку, прогностическую и познавательную ценность имеет эта информация в экологическом, экофизиологическом и экогидрологическом аспектах. Наиболее простым путем надежной интерпретации обнаруженных зависимостей является проведение прямых наблюдений за внутрисезонной динамикой формирования годичного кольца и динамикой окружающей экологической обстановки, что, однако, в большинстве случаев невозможно. В качестве одного из вариантов решения этой научной задачи предлагается применять экофизиологические модели в сочетании с прямыми измерениями δ13C, δ18O и δ2H в древесине и целлюлозе годичных колец.
Interpretation of statistically significant relationships between meteorological parameters like average or daily monthly air temperature, the sum of precipitation of the previous and current year of the tree-ring formation versus variability of dendrochronological parameters (e.g., tree-ring width, maximum latewood density, anatomical parameters of tree rings, and variability of stable isotopes in tree rings) is crucial for the modern dendroclimatology. After the identification of statistically significant correlations, it is necessary to interpret them in a biologically competent manner to adequately understand what eco-physiological mechanisms are behind them, and what meaningful load, prognostic, and cognitive value this information has in ecological, eco-physiological, and eco-hydrological aspects. Like any separately taken biological object, trees of temperate latitudes have their specificity, which differs in connection with hereditary properties of species and physiographic tree growth conditions. The simplest way to reliably interpret the discovered dependencies is to conduct direct observations of the intra-seasonal dynamics of annual tree-ring formation and the dynamics of the surrounding environmental conditions, which is impossible in most cases. Eco-physiological models combined with direct measurements of δ13C, δ18O, and δ2H 18 in wood and tree-ring cellulose are proposed as one of the options for solving this scientific problem.

Abstract

OBJECTIVE
To describe and evaluate the use of preoperative percutaneous ultrasound-guided anchor wire placement to aid intraoperative localization of superficial foreign bodies and abscesses in dogs.

ANIMALS
11 dogs.

CLINICAL PRESENTATION
In a retrospective observational study, the medical records of dogs that underwent surgical exploration of superficial abscesses, guided by anchor wire, between 2018 and 2023 were reviewed for clinical and histopathological findings and complications. Owners or veterinarians were contacted to collect long-term follow-up information.

RESULTS
11 dogs were included. Superficial swelling was the most common clinical presentation. Computed tomography and ultrasound revealed an abscess cavity and suspected foreign body in 9 dogs and an abscess cavity without evidence of a foreign body in 2 dogs. Anchor wires were placed in close proximity to the foreign body or inside the abscess. All documented foreign bodies were successfully located and retrieved. Two dogs suffered minor postoperative complications. No major intra- or postoperative complications were documented. One dog displayed recurrence of clinical signs, but no further surgical management was required.

CLINICAL RELEVANCE
Preoperative percutaneous placement of an anchor wire via ultrasound guidance was successful in aiding intraoperative localization of nonpalpable abscesses and retrieval of foreign bodies. This technique may decrease surgical time, minimize the surgical approach required, and increase the likelihood of successful localization.

Published: July 2024

Abstract
Accompanied by the continuous development of Internet information technology and the promotion of technologies such as big data, artificial intelligence, and machine learning, AI-enabled services are gradually integrated into daily life, and remediation in the face of AI service interactions has also become an inevitable research issue. This study examines the impact of remediation in the event of service failures, particularly in the context of intelligent robot service failures that lead to negative customer experiences. Through the dissection of service failure remediation methods, combined with the customer satisfaction index model, a theoretical research model is constructed from the two aspects of willingness to use and satisfaction, and five hypotheses of remediation are proposed, and then experiments are designed to test them. The results of regression analysis indicated that the mean values of perception and willingness to use in the low anthropomorphism group were 4.875 and 5.052. The mean values of perception and willingness to use in the high anthropomorphism group were increased by 0.718 and 0.649 compared to those of the low anthropomorphism group. The customer’s satisfaction in terms of robot anthropomorphism in the high anthropomorphism was 4.055, and in the low anthropomorphism was 3.410, which indicated that there were positive correlations between the degree of anthropomorphism and both willingness to use and satisfaction have a positive effect, and all five hypotheses of this paper are proved. The purpose of this study is to provide an in-depth analysis of the use of AI anthropomorphization in service failure and service remediation and to offer guidance and references for AI services and related development and design decisions.

Published: July 2024

Abstract
Along with the continuous development of multimedia technology and the deepening of teaching information, virtual reality design factors are crucial to enhancing the impact of the teaching experience. The purpose of this paper is to address traditional art education’s transformational needs and develop an art education teaching system that utilizes virtual reality technology. It also uses the eye-tracking instrument to collect student eye movement data, and after preprocessing the data, such as missing data and noisy trajectory points, it counts the results of each eye movement index in the teaching process. The study showed that some of the students’ eye movement indicators during teaching had a strong correlation with the level of cognitive engagement in learning (P<0.05), and there was no covariance between the indicators. Following the implementation of the teaching mode, the students teaching art under multimedia exhibited a significantly higher level of cognitive engagement in learning (9.74 points) compared to those in the traditional teaching mode (7.14 points). Meanwhile, the eye movement experiment found that the difference in students’ attention concentration in the artwork and work introduction sections was not significant (P > 0.05) when the design elements of the teaching interface were paired with the top of the bottom of the picture and the middle size and the top of the picture and the bottom of the picture and the large size. This paper provides references and their significance for related research, as well as the design of a virtual simulation platform for art teaching.
