Climate change is affecting tree growth and vitality, including potentially accelerating growth rate or exacerbating drought stress. Physiological and phenological changes of a tree may eventually disrupt the beneficial effects that it provides to the ecosystem (‘ecosystem services’). This research examined how the urban forest in Canberra has responded to climate change in the last 20 years. A road

ABSTRACT Tricholoma matsutake is an ectomycorrhizal fungus found in Pinaceae forests in Japan. It produces the “matsutake” mushroom, which has been consumed as an important part of Japanese cuisine since ancient times. Domestic matsutake are among the most valuable special forest products; however, their production in Japan has decreased over the past several decades. In the present study, to facilitate

ABSTRACT Teratosphaeria stem canker is one of the most important diseases to have emerged on non-native plantation-grown Eucalyptus trees cultivated globally. The study assessed the pathogenicity of two Teratosphaeria species associated with Teratosphaeria stem canker and the susceptibility of Eucalyptus grandis and six commonly grown Eucalyptus hybrids to these fungal species in Uganda. The inoculation

The reaction between hypochlorous acid and chlorite ions is the rate limiting step for in situ chlorine dioxide regeneration. The possibility of increasing the speed of this reaction was analyzed by the addition of tertiary amine catalysts in the system at pH 5. Two amines were tested, DABCO (1,4-diazabicyclo[2.2.2]octane) and its derivative CEM-DABCO (1-carboethoxymethyl-1-azonia-4-aza-bicyclo[2.2

Thermo-hydro-mechanical (THM) processing can improve the intrinsic properties of wood, produce new materials, and give desired form and function to new applications. THM treatments change the mechanical properties of wood and may change its viscoelastic properties as well. Therefore, the objective of this study was to assess the viscoelastic properties of THM-treated wood at several humidity and load

The southeastern US has experienced an increase in the number of extreme heat events since the 1970s, due in part to global change. Despite rising temperatures, greater variability in weather has also led to more freeze events across parts of the Southeast, particularly during El Niño winters. Structural variation in forest stands and plant functional diversity can lead to localized micrometeorological

The brown planthopper, Nilaparvata lugens (Stål), is one of the most notorious pests of rice throughout Asia. The brown planthopper have developed high resistance to imidacloprid, a member of neonicotinoid insecticides. Several genes and mutations conferring imidacloprid resistance in N. lugens, especially in eastern and southeastern Asia populations, have been reported. Thus, the key mechanisms of

The development of a feasible and effective method to liquefy soybean protein with the potential to prepare particleboard for wood furniture remains challenging. In this work, different novel liquefaction technologies were proposed to prepare four different soybean protein liquefied products (noted as LSP-Ӏ, LSP-ӀӀ, LSP-ӀӀӀ, LSP-ӀV) that could be used as the matrix of the adhesives to satisfy spraying

The present study investigated the effect of maceration of different species of wood (oak, acacia, chestnut, apricot, mulberry, plum, cherry and grape vine) in three stages of toasting (110, 175, and 200 °C) on the antioxidant capacity, total polyphenol content, changes in color and sensory acceptability of the wine spirit. The addition of different kinds of wooden fragments to the wine spirit led

Aboveground biomass (AGB) is a fundamental indicator of forest ecosystem productivity and health and hence plays an essential role in evaluating forest carbon reserves and supporting the development of targeted forest management plans. Here, we proposed a random forest/co-kriging framework that integrates the strengths of machine learning and geostatistical approaches to improve the mapping accuracies

The assessment of a company’s financial condition is an effective tool, which supports the management system. Nowadays a number of models are available, most often multi-branch ones, which are able to predict the financial situation of an enterprise. Models solely intended for just one line of business are a rarity. As far as the wood sector is concerned, no homogenous model suited to the sector has

This correction stands to correct the listed errors in the original article:

How plant–plant interactions will interact with global change drivers such as increased drought during the regeneration phase is a key question to forecast future vegetation dynamics. Chemical interaction and especially allelopathy and drought have been suggested to affect plant performance synergistically, i.e., that plant under drought stress would be more sensitive to allelochemicals and that exposure

The mechanical behaviour of bamboo is greatly influenced by its transverse properties, which are not easily measured by experiment. This study develops a framework and the computational tools required to evaluate the material and mechanical properties of bamboo in its full-culm form. A numerical model of bamboo as a transversely isotropic material with functionally graded material properties in the

Knowing how evapotranspiration (ET) is mediated by abiotic and biotic pathways is essential to understanding how water affects ecosystem productivity. Recent studies have investigated the average transpiration fraction (T/ET) across sites and biomes, but the temporal variability of the partitioning and its controls are less understood. Here, we examine how water availability may regulate the seasonal

Isoxaflutole (IXF), as a kind of 4‐hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, has been widely used in many kinds of plants. IXF could cause injury in corn included leaf and stem bleaching, plant height reduction or stunting, and reduced crop stand. Safeners are co‐applied with herbicides to protect crops without compromising weed control efficacy. With the ultimate goal of addressing Zea

Transgenic crops producing insecticidal proteins derived from Bacillus thuringiensis are used globally to kill key insect pests and provide numerous benefits, including improved pest management, increased profits, reduced insecticide use, and increased biological control. Unfortunately, such benefits are rapidly being lost by the evolution of Bt resistance by pests.

Cercospora leaf spot caused by Cercospora beticola is the most relevant foliar disease in sugar beet cultivation. In the last decade a decreasing sensitivity of C. beticola towards demethylation inhibitors (DMIs) occurred. Different mechanisms mediating a reduced sensitivity towards DMIs were identified in different plant pathogens so far, such as target site mutations, over‐expression or active excretion

Citrus greening disease (Huanglongbing, HLB) has infected over 90% of Florida's oranges and thus growers are desperate to improve pest management strategies. In this field study, insecticide application efficacy was investigated with liquid chromatography mass spectrometry to determine if insecticide concentration and distribution were effective at killing the target pest Asian citrus psyllids (ACP)

Drosophila suzukii (Matsumura), spotted‐wing drosophila (SWD), is a major invasive pest of soft‐skinned fruits in North America and Europe. Although insecticides are currently the primary method of SWD control, it is imperative to develop alternative management approaches, such as behavioral control through the use of repellents and attractants. This study explores the repellent properties of 2‐pentylfuran

Lack of fitness cost have been reported for multiple herbicide resistance traits, but the underlying evolutionary mechanisms are not well understood. Compensatory evolution that ameliorates resistance costs, has been documented in bacteria and insects but rarely studied in weeds. Dicamba resistant IAA16 (G73N) mutated kochia was previously found to have high fecundity in the absence of competition

The impact on the Profile of Mood States (POMS) of both walking in forest environments and viewing forest landscapes has already been demonstrated in previous research conducted by the authors of this paper. In both walking and viewing, decreases in tension-anxiety (T-A), depression-dejection (D), anger-hostility (A-H), fatigue (F), and confusion (C) were observed and an increase in vigor (V) was observed

Central Himalayan forested catchments provide fresh water supply and innumerable ecosystem services to millions of people. Hence, the understanding of linkages between forests and water is very crucial for availability and quality of water at catchment scale. Therefore, the present study aims to understand the hydrological response of two forested catchments (namely, Arnigad and Bansigad) in the Central

The year 2020 marks the 75th edition of Grass and Forage Science. From its beginnings as the Journal of the British Grassland Society, the journal has grown to be the major international journal with a primary emphasis on grasslands society. In this paper, to mark this anniversary we note the contributions of the editorial team, past and present, and the legacy of the journal by noting some of the

In low‐intensity grazing systems, patch grazing leads to a mosaic structure of short (frequently defoliated) and tall (rarely defoliated) patches, with the stocking rate determining the proportion of these patch types on the pasture. Little is known about the long‐term effects of patch grazing on the productivity of contrasting sward height patches developed under varying stocking rates. On a 12‐year

Seed production is an important grassland feature, as it affects its persistence and botanical composition, and plays an essential role in complex plant–animal interactions. Species‐rich seed mixtures from grasslands can be utilized for ecological restoration. Previous studies used different methods to characterize seed production and did not consider all the main aspects involved; hence, they did

Grassland management impacts ecosystem functioning and is critical for livestock production and biodiversity conservation. Decreasing the stocking rate usually benefits biodiversity but also decreases production per unit area. Here, we assessed the combined effects of cattle herd and pasture size on sward structure, diet quality and daily grazing time while maintaining a constant stocking rate. The

Measurement and monitoring of pasture have been identified as foundations for profitable and sustainable grazing systems. The value that farmers place on pasture assessment in feed management is difficult to ascertain and has seen limited research. The objectives of this study were to test a survey to quantify the perceived value of pasture assessment and identify key criteria for design of pasture

Geopolymer was used as a multifunctional mineral binder to produce laminated veneer lumber (LVL). The main aim of the study was to characterize the various geopolymer binder formulations based on natural kaolin, metakaolin and silica fume. The effect of different combinations of aluminosilicate powder in geopolymer binder was characterized via FTIR, XRD and TGA analysis. The mechanical (shear, bending

Beech laminated veneer lumber (LVL) circular hollow sections for use as nails in temporary geotechnical soil nailing systems were developed within this research. For the soil wall stability, beside a sufficient load carrying capacity of the nail cross section, a load carrying connection between the cement annulus and the nail is necessary. As cement grout ensures the bond between the nails and soil

Wood is an indispensable building material for modern structures. As a kind of biological material, it is more likely than other materials to be affected by the environment. It has been shown that the effect of long-term exposure to humidity will accelerate the decrease in mechanical properties and long-term strength of wood and wood-based products. The most commonly used methods for studying the deterioration

Droughts pose a major risk to agricultural production. By comparing the outputs from an ecophysiological crop model (Sirius) with four drought severity indicators (DSI), a comparative assessment of the impacts of drought risk on wheat yield losses has been evaluated under current (baseline) and two future climate scenarios. The rationale was to better understand the relative merits and limitations

Canopy wetness is a common condition that influences photosynthesis, the leaching or uptake of solutes, the water status and energy balance of canopies, and the interpretation of eddy covariance and remote sensing data. While often treated as a binary variable, ‘wet’ or ‘dry’, forest canopies are often partially wet, requiring the use of a continuous description of wetness. Minor precipitation events

The field population of Spodoptera exigua, an intermittently occurring polyphagous pest, has developed resistance to chlorantraniliprole, while whether or not such resistance carries fitness costs remains poorly understood. Here we selected six generations of the Leshan population (LS‐P) by two‐way selecting method, and obtained a highly resistant strain (CH‐RE) and resistant degnerated strain (CH‐SE)

The present study evaluated the role of having plants at home during the confinement period as a result of the COVID-19 pandemic that deprived people of freely visiting open green spaces. Preferences concerning the quantity of the desired vegetation as well as the ways in which the COVID-19 crisis affected the change of perceptions with regard to having plants at home were also evaluated. A questionnaire

Managing tree health in urban environments is complicated due to the disconnect that exists between novel environmental conditions created by urbanization and those under which tree species evolved. Soils influence tree health and growth, but optimal nutrient and pH recommendations are often informed by agricultural and horticultural norms which do not typically include norms for forest tree species

The aim of the study was to develop a simple and cost-effective method to improve thermal insulation and hydrophobicity of wood. Herein, we attempted to use commercially available silica aerogel powders suspended in ethanol to treat the wood by a simple vacuum impregnation process. The effects of particle size (20 µm and 40 nm) of silica aerogels and the number of impregnation cycles (1, 3, and 5 cycles)

ABSTRACT The effects of early selection in a nursery on field performance were studied in an experiment comprising 2665 cutting-propagated clones of Picea abies (L.) Karst, deriving from 151 half-sib families. The clones were selected from 13,050 seedlings that were evaluated genetically using a randomized block design and measurements of height and growth rhythm in the nursery. The selected clones

ABSTRACT The aim of this study was to analyze and compare the performance of Norway spruce seed sources from Swedish stands of East European origin (SweEast) with material from Swedish (SweSO) and East European (EastSO) seed orchards, and with material from Swedish (SweS) and East European (EastS) unimproved stands. The seed sources were field tested at six locations in southern Sweden and assessed

ABSTRACT Several insect species, including those belonging to Geometridae, pose serious threats to oak stands, primarily by causing cyclic defoliation and increasing the vulnerability of trees to adverse secondary factors. Our major study goal was to compare the effectiveness of two types of pheromone traps, funnel vs. bucket traps, for capturing Operophtera brumata males, and the effectiveness of

ABSTRACT Human intervention in global nitrogen cycling has led to excess reactive nitrogen (Nr) flows to the environment, impacting terrestrial ecosystems as well as the quality of the atmosphere and waterbodies. This paper presents the results of a study that quantified and compared the main flows of Nr through forest land and wetlands in Latvia and Estonia using substance flow analysis approach based

ABSTRACT The effect of site preparation (mixed mounding and removal of the humus layer) under a shelterwood of mixed boreal forest along a forest interior-edge gradient on Norway spruce (Picea abies) seedlings was studied two years after planting. Mounds had a positive effect on root development, ectomycorrhiza formation and the absorption of nitrogen (N) and phosphorus (P) in the seedlings, and augmented

ABSTRACT In 2018, global crude steel production was approx. 1.8 gigatonnes while its direct CO2 emissions stood at 2 giga tonnes (2017), representing 23.5% of all direct industrial emissions. Globally iron and steel industry (ISI sector) is the second largest emitter after the cement industry while in Finland and Sweden the ISI sector is the largest industrial source of fossil CO2. Biocarbon received

ABSTRACT Forest road network plays a key role in shortening the response time of firefighting activities. Therefore, evaluation and improvement of the ability of firefighting of the forest roads are essential. The widely used travel time criterion evaluation showed that firefighters can reach the areas of fires by walking and carrying portable fire equipment. However, the firefighting capability provided

ABSTRACT Dahurian larch (Larix gmelinii Rupr.), Korean spruce (Picea koraiensis Nakai), and Manchurian fir (Abies nephrolepis Maxim) are valuable tree species of northeast China. Management tools are required for these species to support the industrial and ecological development of forest ecosystems of China. This study aimed to develop taper equations for these species. Five well-known taper equations

ABSTRACT The share of women among forest owners is growing in the traditionally masculine family forest sector. The present study continues the research on women who own forest in the Nordic setting. The focus is on the behaviour and role of rural female forest owners in Finland, as well as on the benefits of peer learning when building self-efficacy as a forest owner. The qualitative data consist

ABSTRACT Women have been historically underrepresented in the forest sector. Given a graying workforce, there is a significant opportunity to diversify the sector via a younger generation entering the industry. To a large extent, the gender situation in the forest sector is influenced by the education of employees in the sector. Therefore, it is beneficial to know the perceptions of women student leaders

Cities in sub-Saharan Africa are rapidly growing and transforming. This leads to increased demand for accessible urban green spaces (UGSs). In order to address these issues, various efforts have been made. Despite the abundant scientific literature available on the accessibility of UGSs in many parts of the world, only a few studies have been conducted in sub-Saharan Africa and particularly in Ethiopia

In the United States, urban forests represent 35% of all urban land cover, and deliver benefits to nearly two-thirds of the population. As global urban populations continue to rise, however, redevelopment is continually reported as a major factor in reduced canopy cover. While urban trees provide us with measurable benefits when adequately maintained, their costs when not cared for remains poorly understood

Urban green space is an important element of well-being. It is still, however, lacking of research on green space demand analyzing based on social platform data. This research uses social platform data to evaluate people's demand for urban green space under the background of the global COVID-19 pneumonia. Using the micro-blog database of geographical markers and keywords, this research quantified the
