Published: March 2022

The impact of warming and wetting on the ecological environment of the Qinghai-Tibet Plateau (TP) underthe background of climate change has been a concern of the global scientific community. In this paper, the optimizedinterpolation variational correction approach is adopted for the analysis of monthly high-resolution satellite precipitationproducts and observations from meteorological stations during the past 20 years. As a result, the corrected precipitationproducts can not only supplement the“blank area”of precipitation observation stations on the TP, but also improve theaccuracy of the original satellite precipitation products. The precipitation over the TP shows different spatial changes inthe vegetation growing season, known as the time from May to September. The precipitation in the vegetation growingseason and leaf area index (LAI) in the following month show a similar change pattern, indicating a“one-month lag”response of LAI to precipitation on the TP. Further analysis illustrates the influence of water vapor transport driven bythe Asian summer monsoon. Water vapor derived from trans-equatorial air flows across the Indian Ocean and ArabianSea is strengthened, leading to the increase of precipitation in the central and northern TP, where the trend of warmingand wetting and the increase of vegetation tend to be more obvious. By contrast, as a result of the weakening trend ofwater vapor transport in the middle and low levels in southern TP, the precipitation decreases, and the LAI shows adowntrend, which inhibits the warming and wetting ecological environment in this area.

Published: March 2022

The aim of this study was to describe in ewes and dairy cows, uterine, cervical and vaginal aspect in a physiological context, using cytological and histological techniques as a gold standard. Reproductive tracts of slaughtered cows and ewes were collected from a commercial slaughterhouse in the region of batna. The reproductive phase of each tract was estimated by ovarian performance. Cytobrush samples from the uterus and cervix were prepared. The smears were stained and examined for differential cellular counts. Furthermore, biopsy samples fixed in 10% buffered formaldehyde, embedded in paraffin, sectioned and stained with hematoxylin and eosin. The results showed no significant difference (P≥0.05) for cellular densities between cervical and uterine in different phases of estrus cycle (follicular and luteal phases) of the ewes and cows. However, there were significant differences in the percentage of neutrophil cells of uterine and cervix smears in tracts with a corpus luteum (CL) or without a CL. in spite of, the following histological changes were observed during the estrous cycle in cows and ewes. Histological examination was a useful diagnostic method that provided rich detail on endometrial inflammation, and allowed evaluation of different components of the tissue such as the epithelium, lamina propria, endometrial glands, and blood vessels. Therefore, in cows and ewes cervical smears may be used for evaluation of uterine condition.

Authors: Stoynova Anna , Bonev Borislav
Published: March 2022

This paper discusses the applicability of pulsed and lock-in thermography using Fourier transform processing to diagnose specific types of defects in Multilayer FR-4 Substrates. Digital thermal models of test specimens with different types of defects have been created. Based on the obtained results, the methods are compared in terms of applicability and reliability in defect detection. The results show that by these methods can be detected and characterized in terms of geometric dimensions and type of certain types of specific defects arising in the production of FR-4 multilayer substrates. The presented results show that there is no obstacle to the detection of defects in different layers of the multilayer substrate within the same measurement, as well as the possibility of detecting many types of defects.
Learning Mathematics through WhatsApp Groups in University Preparatory Program during the COVID-19 Pandemic
Authors: Ofori-Kusi Daniel , Tachie Simon Adjei
Published: March 2022

This study examined the impact of learning through social media (WhatsApp learning groups) on university students' mathematics achievements in the first-year university preparatory program when they engaged in some form of social media learning interaction compared with students who did the same module with a traditional face-to-face interaction learning approach. The study was undertaken using a quantitative research method. It employed a randomised Post-Test-Only with a Non-equivalent Groups design to investigate the only statistically significant difference between university students who studied through the traditional face-to-face lecturing approach and students who utilised a blended approach to learning mathematics. The study population comprised first-year university students enrolled for the university extended programme offered by all universities in South Africa. The sample consisted of 192 experimental groups and 341 control group students conveniently sampled from a university in South Africa. The main instruments used in this study were two standardised semester exams. These tests were checked and moderated by senior mathematics lecturers to ensure they conformed with the module content and satisfied all assessment policies of the university. The Cronbach alpha coefficient was used to measure the consistencies in these two-semester exams. The study's main finding showed no statistically significant difference in results between students who studied Mathematics through a face-to-face lecturing approach and students who studied mathematics through a blended learning approach. The study concludes that the latter performed slightly better than students in the former, confirming that a WhatsApp learning group can be a viable alternative to the teaching and learning at the university when face-to-face learning is not possible, as for an example in the Covid-19 era. The study recommends that more profound research be conducted to identify and analyse positive indicators when learning is done through social media interaction.
Time Divested or Time Invested? Freshmen’s Perspectives and Reflective Experiences on Interactive School Learning
Authors: Tachie Simon Adjei , Kariyana Israel
Published: March 2022

This study sought to research first-year South African university students’ attitudes towards interactive school learning and then to determine their perspectives and reflective experiences regarding interactive learning. Data was gathered during the first week of their first university lectures. The sample was 129 freshmen. The study adopted a mixed-method approach that utilized a sequential explanatory research design. Data was gathered through questionnaires and interviews. Quantitative data was coded and analysed through descriptive statistics using SPSS version 23, while qualitative data was thematically analysed through content analysis. Permission to conduct the study was granted by the lecturers and the participants. It emerged from the study that, though participants were positive about the provision of interactive school learning, their school experiences told different stories about such activities. Participants valued interactive school learning as it improves learners’ socialization experiences, communication skills, and thinking skills. Interactive school learning also promotes teamwork and personal engagement, which are necessary to improve the quality of education. The study concluded that, while interactive school learning added value to education, most schools did not offer such opportunities to enhance learning experiences. The study recommends that schools offer school-based opportunities and teaching practices that accommodate learners’ varied learning styles across all subjects.

Published: March 2022

Para entender os motivos pelos quais acadêmicos buscam através de atividades físicas, esportivas e de lazer a satisfação de suas necessidades intrínsecas e extrínsecas, faz-se necessário aprofundar-se na temática motivação de acadêmicos para preencher lacunas na literatura e favorecer a atuação dos profissionais de educação física para esse grupo em específico. O objetivo do estudo foi verificar os principais motivos associados à prática de atividades físicas, esportivas e de lazer por acadêmicos da Universidade Federal de Juiz de Fora (UFJF). Para tanto, 484 acadêmicos da UFJF, com média de idade de 21,1 ± 2,9 anos, responderam um questionário com questões sobre pratica de atividades físicas e motivos para essa prática. Dos entrevistados, 94,21% já praticaram alguma modalidade de esporte ou lazer, destes 42,4% praticam atualmente alguma atividade física, esporte ou lazer. Os motivos mais citados para a prática de atividades físicas, esporte ou de lazer, foram saúde, prazer e estética. A maioria dos acadêmicos da UFJF já praticaram alguma vez atividades físicas, esportivas ou de lazer, mas apesar disso, nem metade dos entrevistados continuam praticando tais atividades, e essas parecem ser motivadas por preocupações com a qualidade de vida dos indivíduos, tanto no aspecto físico, psicológico e social.

Authors: Dantas Estélio Henrique Martin , Dantas Karollyni Bastos Andrade , Carvalho Paula Esteves , Costa Frederico Barros , Lugão Elizabeth Carvalho
Published: March 2022

Introdução: O Rendimento Esportivo é usado para classificar atletas, atribuir pontuações, visando equilibrar as competições. Por exemplo, a Classificação Funcional do Esporte Paralímpico para determinar elegibilidade, classifica paratletas de acordo com suas deficiências, em subcategorias das modalidades esportivas, para manter a equanimidade de oportunidades. O Brasil patrocina atletas e paratletas para se dedicarem aos treinos e competições, oferecendo cinco categorias de bolsas: Base, Estudantil, Nacional, Internacional e Olímpico/Paralímpico. A Bolsa Atleta Categoria Pódio é a mais alta e pretende patrocinar atletas com chances de medalha. O atleta para se candidatar deve cumprir os pré-requisitos do programa. Objetivo: Elaborar uma proposta de instrumento para mensurar o Rendimento Esportivo (Instrumento Dantas de Avaliação do Rendimento Esportivo – IDARE). Metodologia: Partindo-se de uma revisão integrativa da literatura bibliográfica disponível e de um Brainstorming chegou-se à conclusão de que o mais adequado seria utilizar os critérios de concessão do Bolsa Atleta, hierarquizando-os e atribuindo valores ponderados distintos, capazes de quantificar o currículo esportivo individual. Resultados: O IDARE é formado por uma tabela com valores quantitativos relacionados ao rendimento esportivo do atleta. O quadro tem seis categorias de rendimento esportivo: Base, Estudantil, Nacional, Internacional, Olímpico e Pódio. Cada categoria de desempenho apresenta itens que atribuirão pontos ao avaliado, corrigidos por um fator de correção específico de cada categoria. Conclusão: O IDARE pretende suprir a ausência de informações sobre o rendimento esportivo para realização de pesquisas em ciências do esporte, possibilitando comparar distintas modalidades e atletas.

Published: March 2022

En el entrenamiento deportivos es necesario incursionar en instrumentos de fácil acceso y de alta confiabilidad que puedan ser de ayuda a entrenadores. Si bien que en la actualidad la tecnología es un medio indispensable para el perfeccionamiento de cualquier disciplina deportiva, muchos entrenadores tienen que afrontar el no tener acceso a equipamientos tecnológicos para evaluar y controlar el nivel láctico de un corredor. Los índices de resistencia establecen indicadores para determinar el nivel de resistencia láctica que permiten establecer una dependencia entre diferentes dúos de distancias competit6ivas cercanas. Es por esto que se parte del siguiente problema: ¿Cómo establecer los índices de resistencia en corredores ecuatorianos en categoría senior? A fin de determinar esos índices en  los corredores ecuatorianos senior se procesaron  los resultados de distancias entre 100-200, 200-400, 400-800 y 800-1500 metros, de un total de 381 corredores, seleccionados de la base de datos de la Federación Ecuatoriana de Atletismo y mediante fórmulas de correspondencia, aplicando los   percentiles fueron determinados tres índices de resistencia: ∆XT, ∆XP y ∆XV para dúos de pruebas, que se constituyen en baremos de control del nivel de la resistencia láctica de esos corredores.

Authors: Alanis Francisco de Borja Rodríguez , Moya Luis Roberto Garza , Rosas Claudia Rocío Tovar , Burciaga Josué Mizraim Arreola , Barraza Daniel Pérez
Published: March 2022

En la actualidad, es una preocupación para las universidades la falta de visón de los estudiantes, al no identificar por ellos mismos, la importancia en asignaturas con trascendencia curricular. La presente investigación plantea la problemática existente en la educación superior, particularmente en carreras relacionadas con la gráfica y el arte, como lo son Diseño Gráfico, Diseño de Interiores, Diseño de Modas, y más recientemente la Ingeniería en Animación y Efectos Visuales, en donde ciertas asignaturas son invariablemente estigmatizadas como “de relleno” por los propios alumnos y por lo tanto ubicadas como desvinculadas del curriculum formal en relación con el sector productivo. La presente investigación plantea el empleo del juego de rol (RPG por sus siglas en inglés) como estrategia didáctica para mejorar los aprendizajes significativos en dichas asignaturas, una herramienta que ayude en el desarrollo de competencias (habilidades, conocimientos y actitudes) empleando a su vez las Tics como parte integral de dicho esfuerzo y mediante la autogestión que le permita al participante académico enfrentar las necesidades del mercado laboral actual.

Published: March 2022

In this paper we introduce the concept of $P_1$ property of sequences, consisting of positive integers and prove two criteria revealing this property. First one deals with rather slow increasing sequences while the second one works for those sequences of positive integers which satisfy certain number theoretic condition. Additionally, we prove the unboundedness of common divisors of distinct terms of sequences of the form $(2^{2^n} +d)^\infty_ {n=1}$ for integers d≠1.

SENSITIVITY ANALYSIS OF THE FIRST CIRCUIT OF COLD CHANNEL PIPELINE RUPTURE SIZE FOR WWER 440/270 REACTOR
Authors: Hovsepyan A.D.
Published: March 2022

This calculation describes an accident to analyze and study the emergency instructions in case of fracture in the airtight zone of the first circuit. Sensitivity analysis was performed to determine the extent of the fracture, when a highpressure feeder pump remains 100 N/cm2 higher than the saturation pressure in case of emergency pressure of the circuit (the pressure drop allows the main circulating pumps work). The conventional diameter of the fracture is 29 mm and the schedule of the development of events is given in the study.
ON A POSSIBLE INFLATIONARY MODEL OF THE EARLY UNIVERSE
Authors: Avagyan R.M. , Harutyunyan G.H. , Sushkov S.V.
Published: March 2022

We consider the inflationary regime of the expansion of the Universe within the framework of the modified Jordan theory. In this model, a specific cosmological scalar is an analog of the Einstein cosmological constant L, which is connected with the Hubble parameter by the power-law $\varphi(\Phi) = \alpha H^4$. As a result, a stage of hybrid inflation is obtained, at the end of which the acceleration parameter becomes zero.
HYPERNUCLEAR MATTER IN COMPACT STARS
Authors: Sedrakian A.D.
Published: March 2022

We discuss the recently developed energy density functional for hypernuclear matter, which is based on simultaneous calculation of heavy single-$\Lambda$ hypernuclei and compact stars containing hypernuclear core. The nucleonic matter is described in terms of a density-dependent parametrization of nucleon-meson couplings, whereas the hyperonmeson couplings are deduced from the octet model. We identify the parameter space of hyperon-meson couplings for which massive stellar configurations with $M \leq 2.1 M_\odot$ exist and at the same time the laboratory $\Lambda$-hypernuclear data can be described.
ON A CONJECTURE IN BIVARIATE INTERPOLATION
Authors: Toroyan S.Z.
Published: March 2022

Denote the space of all bivariate polynomials of total degree n$\leq n$ by $\Pi_n$. We are interested in n-poised sets of nodes with the property that the fundamental polynomial of each node is a product of linear factors. In 1981 M. Gasca and J. I.Maeztu conjectured that every such set contains necessarily $n+1$ collinear nodes. Up to now this had been confirmed for degrees $n \leq 5$. Here we bring a simple and short proof of the conjecture for $n = 4$.

ON CANONICAL NOTION OF $\delta$-REDUCTION AND ON TRANSLATION OF TYPED $\lambda$-TERMS INTO UNTYPED $\lambda$-TERMS
Authors: Nigiyan S.A. , Khondkaryan T.V.
Published: March 2022

In the paper typed and untyped $\lambda$-terms are considered. Typed $\lambda$-terms use variables of any order and constants of order $\leq$1. Constants of order 1 are strong computable functions with indeterminate values of arguments and every function has an untyped $\lambda$-term that $\lambda$-defines it. The so-called canonical notion of $\delta$-reduction is introduced. This is the notion of $\delta$-reduction that is used in the implementation of functional programming languages. For the canonical notion of $\delta$-reduction the translation of typed $\lambda$-terms into untyped $\lambda$-terms is studied.

We prove that the free Burnside groups $B(m,3)$ of period 3 and rank $m\geq1$ have Magnus's property, that is if in $B(m,3)$ the normal closures of $r$ and $s$ coincide, then $r$ is conjugate to $s$ or $s^{-1}$. We also prove that any automorphism of $B(m,3)$ induced by a Nielsen automorphism of the free group $F_m$ of rank $m$. We show that the kernel of the natural homomorphism $\text{Aut}(B(2,3)) \rightarrow GL_2(\mathbb{Z}_3)$ is the group of inner automorphisms of $B(2,3)$.

Published: March 2022

El mucílago del nopal (Opuntia ficus-indica) es un hidrocoloide que ayuda a regular el contenido de agua celular en la planta para sobrevivir durante períodos largos de sequía. Está compuesto principalmente de azúcares neutros y ácidos y la concentración de estos puede cambiar debido a las etapas de madurez de los cladodios o nopales. Por esta razón, la hipótesis de este trabajo fue que los estados de madurez del nopal producen cambios en la composición química del mucílago, y el objetivo de este estudio fue caracterizar el mucílago de nopal de tres diferentes estados de madurez, a saber, tierno, joven, maduro según su composición química proximal, análisis de grupos funcionales, identificación y cuantificación de azúcares, así como el microanálisis elemental de los respectivos nopales. Los resultados mostraron que el mucílago de nopal maduro presentó mayor contenido de cenizas, fibra y azúcares totales, 34.8, 47.5 y 14.32 g 100 g-1 respectivamente, y de ácido urónico con 34.5 %, respecto a los demás mucílagos. Los grupos funcionales identificados en los tres mucílagos (O-H, C-H de metileno, C=O de carboxílico, C-N de aminas, y enlaces C-O de alcohol primario y secundario) fueron iguales. Sin embargo, mostraron diferencias en la intensidad de la banda entre los tres mucílagos. En las diferentes muestras de nopal se identificaron elementos químicos (minerales) como potasio, magnesio, calcio, fósforo, azufre, silicio y cloro. Los azúcares totales, fibra, cenizas, cristales de calcio y ácidos urónicos aumentaron con el estado de madurez del nopal. Los resultados generados podrían ser un potencial relevante para su aplicación en la remoción de metales pesados presentes en cuerpos de agua.

How to correctly make medical certificates? Avoid pitfalls!

Making medical certificates is an important part of the administrative work of physicians. A medical certificate is based on a physician’s examination to establish that a patient can obtain a benefit or does not need to fulfil an obligation. Deontologically, a physician draws up this certificate truthfully, objectively, carefully and discreetly. Since certificates are intended for third parties, it is important to take patient-physician confidentiality into account, as well as the GDPR privacy regulation (General Data Protection Regulation). The date of editing is stated on the certificate, possibly another date can be stated retrospectively while taking into account the obligatory or optional communication with another physician with an extra-curative assignment. When a certificate is purely based on a patient’s statement, this is referred to as a ‘dixit certificate’. To limit the impact of (long-term) absence certificates, it is important to enter into a dialogue with the patient about the length of the absence. Closer cooperation with a physician of a student guidance centre (SGC) or an occupational physician can lead to an adjustment of the learning and working conditions of the person concerned. Insurance certificates may only state the current state of health. When in doubt, a physician specialized in insurance medicine can be asked for advice.

O conhecimento detalhado das paisagens em microbacias hidrográficas são fundamentais para avaliação dos impactos ambientais causados por ação humana e tomada de decisões sobre os recursos naturais. Nesse contexto, objetivou-se com o presente estudo analisar e disponibilizar informações sobre as características geométricas, topográficas, hidrográficas e a dinâmica de cobertura do solo da microbacia do rio Jaçanã. Para a análise dos dados, foi utilizado geotecnologias e equações. A microbacia tem área de 149,94 km2, perímetro de 79,30 km, formato alongado, baixa susceptibilidade a enchentes (ponto de vista geométrico), altitudes entre 181 a 247, predominância de relevos suave ondulado e plano, rede de drenagem de 129,82 km, padrão dendrítico de 4ª ordem, densidade de nascentes baixa e densidade de drenagem média, canal principal reto, coeficiente de manutenção de  1.155 m2 m-1 e tempo de concentração de 11,63 h. Entre 1988 a 2021, a cobertura de floresta nativa foi reduzida de 140,09 km2 (93,43%) para 84,35  km2 (56,26%) na microbacia e, de 15,29 km2 (63,18%) para 10,88 km2 (44,6%) na zona ripária, em função do avanço da agropecuária. A microbacia tem potencial para o desenvolvimento da agropecuária, contudo, considerando a legislação vigente que trata da proteção da vegetação nativa no país e expansão de áreas antropizadas, concluímos que há uma necessidade imediata na execução de planos de recuperação da vegetação nativa na microbacia, especialmente na zona ripária, para garantir a manutenção, qualidade e a disponibilidade dos recursos naturais.

GIS Assessment of Munich's Urban Forest Structure for Urban Planning
Authors: Pauleit Stephen , Duhme Friedrich
Published: March 2022

A geographic information system (GIS) was developed and applied to assess the spatial pattern and environmental functions of the urban forest in the city of Munich. Urban land cover types were delineated as the underlying spatial units, characterized by physical and landuse attributes such as the percentage cover of built-on land and vegetation. The urban forest was described as the cover of trees and shrubs and the maximum age of trees. The survey was coupled with statistical databases and environmental data such as a habitat survey and thermal infrared photography. Trees and shrubs covered approximately 5,400 ha (13,300 ac) of land, or 18% of Munich's surface area. The spatial pattern of the urban forest was closely linked with the general zoning of different land use and building density. The relationship between cover, size, and age of woody vegetation and the incidence of woodland indicator birds was used to assess the role of the urban forest for urban nature conservation, and potential habitat links of closely neighboring woodlands were identified by means of the GIS. Furthermore, it was shown that the urban forest can effectively reduce air temperatures during hot summer days. Specific urban forestry programs and quantitative targets were proposed for urban zones. These would increase the forest cover to 22% of the city's surface area. An estimate for the overall costs for the establishment of the additional forest areas is given.
Urban Forestry Research in Europe: An Overview
Authors: Konijnendijk Cecil , Randrup Thomas , Nilsson Kjell
Published: March 2022

A comprehensive European overview of recent and ongoing research in Europe was carried out within the framework of COST Action E12, "Urban Forests and Trees," a pan-European research network. This paper presents some of the main findings of a comparative analysis of 20 individual country reports. The analysis shows that research on urban forests and urban trees in Europe has a wide scope and is rather fragmented and uncoordinated. Universities and state research institutes, mostly with a forestry or horticultural background, dominate the research. Relevant research is primarily funded from state and municipal sources. Significant differences exist between countries with regard to the level of activity, research topics and institutions involved.
Fertilizer Rate and Type Impacts Magnolia and Oak Growth in Sandy Landscape Soil
Authors: Gilman Edward , Yeager Thomas , Kent Donald
Published: March 2022

Southern magnolia (Magnolia grandiflora) planted as 3-L (1-gal) liners into sandy soil did not respond to nitrogen applications above 20 g N/m2 (4.2 lb N/ 1,000 ft2) per year the first 2 years after planting. The 40 g N/m2 (8.3 lb N/1,000 ft2) per year rate resulted in greater height than the 20-g (4.2-lb) rate in the third year and greater height and trunk diameter the fourth year after planting. Nitrogen rates greater than 40 g N/m2 did not result in more growth. Seedling magnolia and 10- to 13- cm (4- to 5-in.) caliper field-grown live oak (Quercus virginiana) trees receiving nitrogen soon after transplanting responded the first year of application by growing faster than those that received no nitrogen. Nitrogen source had little impact on growth or tissue nitrogen concentration (1.4%) of 10- to 13-cm-caliper live oak in the first 3 years after field transplanting, and there was no N source effect on root extension from the trunk. All fertilizers containing nitrogen promoted growth. Nitrogen applications increased trunk growth on 23-cm (9-in.) caliper live oak beginning about 16 months after transplanting with a tree spade. Potassium and/or phosphorus, when applied in conjunction with nitrogen, had no effect on growth.
Expenditures Associated with Conflicts between Street Tree Root Growth and Hardscape in California, United States
Authors: McPherson E. Gregory
Published: March 2022

A survey of 18 California cities indicated that approximately $70.7 million (se $11.1 million) was spent annually statewide due to conflicts between street tree root growth and sidewalks, curbs and gutters, and street pavement. The largest single expenditure was for sidewalk repair ($23 million, se $9.5 million), followed by curb and gutter repair ($11.8 million, se $2.6 million), and trip and fall payments and legal staff time ($10.1 million, se $2.2 million). Property owners paid 39% and 17% of tree-related sidewalk and curb and gutter repair costs, respectively. Substantial funds were invested to remove and replace trees in conflict with hardscape ($6.8 million, se $3.6 million), and for inspection and repair administration programs ($5.9 million, se $1.3 million). Root pruning ($2.5 million, se $2.0 million) and root barriers ($676,854, se $175,655) were the most important mitigation and prevention measures. Restricted planting space and the type of tree species selected were reported as the most important factors responsible for hardscape damage.
Induction of Systemic Acquired Disease Resistance in Plants: Potential Implications for Disease Management in Urban Forestry
Authors: Percival Glynn
Published: March 2022

Systemic acquired resistance (SAR) is the phenomenon whereby a plant's own defense mechanisms are induced by prior treatment with either a biological or chemical agent. The concept of SAR has been widely recognized and studied for the past 100 years in relation to increasing resistance to fungal, bacterial, and viral pathogens of economically important crop plants. The use of SAR as part of a disease management strategy in relation to urban forestry has received little scientific investigation despite offering some potential for tree pathogen control. The objectives of this paper are to discuss the concepts of SAR and, where applicable, indicate how SAR may be incorporated into a disease management system by urban foresters. Areas discussed include historical background, persistence of SAR, mechanisms of SAR, induction of SAR by biological organisms and chemicals, interplanting with flowering woody plants to promote an SAR response, and SAR in woody plants.
Effect of Urban Expansion on Arbuscular Mycorrhizal Fungal Mediation of Landscape Tree Growth
Authors: Stabler Linda , Martin Chris , Stutz Jean
Published: March 2022

Field and glasshouse pot studies were conducted to determine effects of urban expansion on arbuscular mycorrhizal fungal (AMF) populations and AMF impact on landscape tree growth. Soil and root segments were collected and evaluated for root colonization by AMF of trees at remnant Sonoran Desert sites and nearby, formerly desert, drip-irrigated residential landscape sites in the Phoenix, Arizona, USA, metropolitan area. Native desert trees had greater colonization by AMF than residential landscape trees, and AMF species composition differed at the two site types. A glasshouse pot experiment using AMF inocula from the desert or residential sites was used to evaluate AMF effects on growth and carbon fluxes of three landscape trees in 12-L (3-gal) polyethylene containers relative to non-AMF controls. Growth and P nutrition of Acacia smallii and Fraxinus uhdei were increased by AMF colonization. Acacia carbon assimilation was increased by AMF root colonization. Soil respiration by Acacia and Fraxinus tree roots was decreased by AMF root colonization. Growth and carbon fluxes of Parkinsonia microphylla were not affected by AMF. We conclude that AMF might significantly increase landscape tree carbon storage potential depending on tree species, AMF population characteristics, soil water availability, and improved P uptake.
