The anticipated increase in extreme disturbance events due to climate change is likely to expose Norway spruce (Picea abies (L.) Karst.) dominated forests in northern Europe to new conditions. Empirical data on the resilience of such natural (unmanaged) forests to disturbance and the long-term patterns of regeneration in its aftermath are currently scarce. We performed a quantitative assessment of

Evaluation of the glue line in CLT panels and in other wood composite products in general is of great interest. Non-destructive methods such as determination of the velocity of ultrasound waves going through the materials are commonly applied to evaluate wood products. The present work is aimed at mapping ultrasound velocity (UV) to identify problems of glue line delamination in CLT panels of 3 and

• Key message Parametric indirect models derived from stem analysis of dominant trees were more robust than rule-based machine learning techniques for predicting Site Index of Scots pine stands as a function of climate. • Context The uncertainties derived from climate change make it necessary to develop new methods for representing the relationships between site conditions and forest growth. • Aims

• Key message Pronounced additive genetic variation and high narrow-sense heritability for lesion length caused by Neonectria neomacrospora were found in a Nordmann fir progeny test. Significant inbreeding depression was detected in traits important for Christmas tree production. Recurrent selection for multiple traits would be successful for Christmas tree quality traits. • Context The fungal pathogen

Previous Genetic Pest Management (GPM) systems in diamondback moth (DBM) have relied on expressing lethal proteins (‘effectors’) that are ‘cell‐autonomous’ i.e. do not leave the cell they are expressed in. To increase the flexibility of future GPM systems in DBM, we aimed to assess the use of a non cell‐autonomous, invertebrate‐specific, neurotoxic effector – the scorpion toxin AaHIT. This AaHIT effector

Combining both biological diversity and cultural significance, populations of big trees in Japan are considered important. Furthermore, individual specimens, often with broken and unusual tree form, are highly striking and create a ‘sense of place’ in a locale. The giant Castanopsis sieboldii trees belonging to the family Fagaceae have a trunk circumference of over 3 m. These trees are distributed

Uncertainty information associated with urban forest models are beneficial for model transparency, model development, effective communication of model output, and decision-making. However, compared with the extensive studies based on the applications of urban forest models, little attention has been paid to the uncertainty of the output from these models. In this study, bootstrap and Monte Carlo simulation

This study aims to investigate the heterogeneous preferences for ecological services, cultural services and facilities, and information-related facilities in an urban wetland park in Xixi National Wetland Park, China, and explore choice inconsistencies among individuals via a multi-profile best-worst scaling choice experiment. Face-to-face surveys were conducted in the winter 2018 and summer 2019,

Urban forests, integral to a city’s critical infrastructure, are traditionally under the mandate of local governments, yet in reality, the decision-making for their conservation is influenced by a myriad of factors operating at the neighbourhood level. In some neighbourhoods, decisions are heavily influenced by formal Resident Associations (RAs). Using a case study approach, in depth interviews were

Robinia pseudoacacia is a widely planted pioneer tree species in reforestations on barren mountains in northern China. Because of its nitrogen-fixing ability, it can play a positive role in soil and forest restoration. After clear-cutting of planted stands, R. pseudoacacia stands become coppice plantations. The impacts of shifting from seedling to coppice stands on soil bacterial community and soil

ABSTRACT Stump removal is considered as the most effective method to reduce losses caused by root rot fungi, including Heterobasidion root rot. To evaluate the persistence of Heterobasidion spp. in root fragments left on site after stump removal, and to analyse the ecological impact of stump removal, five permanent sample plots were established in Latvia and samples were taken immediately after stump

The influence of the grain angle on the cutting force when milling wood is not yet detailed, apart from particular cases (end-grain, parallel to the grain, or in some rare cases 45°-cut). Thus, setting-up wood machining operations with complex paths still relies mainly on the experience of the operators because of the lack of scientific knowledge easily transferable to the industry. The aim of the

Climate change is projected to have a major influence on forest tree populations and composition. Translocation of species outside their historic range has been suggested to maintain healthy forests and tree species. The introduction of exotic species into botanical gardens and arboretums worldwide demonstrates the ability of many trees to grow outside their natural habitat and may play an important

With ongoing rapid urbanization, urban biodiversity conservation is becoming a primary issue for the maintenance of urban ecosystem functions, and given that birds play valuable ecosystem roles, their preservation is a matter of both ecological and social importance. Although it is generally considered that urban areas have low biodiversity and ecosystem value, these areas can serve as important wintering

Urban forests affect land surface temperature (LST) within a city due to the cooling effect of transpiration. The latter depends on tree health, but it can also be affected by the structure and composition of forest, as a mono-species environment may potentially worsen the health of urban forest. The following hypotheses are therefore proposed: a) greater tree diversity within urban forest results

Water availability and conservation are among today’s top global issues, and urban irrigated landscapes have a pronounced role to play in developing solutions to water scarcity problems. Innovative approaches are needed to promote water conservation outside of the home, and social norms comprise one such type of strategy that can accelerate the use of landscape water conservation technologies and practices

Healthy Trees – Healthy People (HT-HP) is an outreach and education program created to enlist and train participants in exotic pest detection while providing them with structured opportunities to connect with urban nature and increase their physical and emotional health. HT- HP creates infrastructure to increase engagement by the urban populace in the urban tree canopy. The program solicits participants

Forest City is a new city project being built from scratch on four artificial islands off the coast of Malaysia by one of China’s largest property developers. Designed to accommodate up to 700,000 people, Forest City is created by and for Chinese nationals as a gated, luxury enclave in Malaysia. While Forest City is built on top of Malaysia’s largest seagrass field and destroys or damages coastal mangroves

Different types of structures and substrates are used for urban extensive green roofs. However, there is not enough information about the performance of these structures and substrates for growing edible plants in tropical climate conditions. This study evaluates the best combination of three different modular extensive green roof structures and two types of local substrates (compost and soil + biochar)

Growth in insect pest populations poses a significant threat to ecosystem functions and services, societal development, and food security in alpine regions under climate change. Risk assessments are important prioritization tools for pest management, which must be used to study insect pest expansion in alpine ecosystems under global warming. We used species distribution modeling to simulate the current

The hot-disk method is a transient method for the measurement of thermal properties. This method can measure both the thermal conductivity and thermal diffusivity in a short time for isotropic materials. To establish a method for measuring the thermal properties of wood by the hot-disk method, the relationship between the thermal properties of wood obtained by the hot-disk method and those obtained

The thermal degradation reactivities of cellulose and hemicellulose are substantially different in Japanese cedar (Cryptomeria japonica, a softwood) and Japanese beech (Fagus crenata, a hardwood). Uronic acid and its salts act as acid and base catalysts, respectively, and their specific placement in the cell walls has been considered a factor that influences degradation reactivity. In this study, the

In temperate Europe, oak-dominated forests are widespread, supporting high biodiversity and providing important ecosystem services. Insufficient natural regeneration has, however, been a concern for over a century. The objective of this study was to gain insights into differences in regeneration success using artificial and natural regeneration techniques for reforestation of oak (Quercus robur L.)

In the woodworking industry, detection of annual rings and location of pith in relation to timber board cross sections, and how these properties vary in the longitudinal direction of boards, is relevant for many purposes such as assessment of shape stability and prediction of mechanical properties of timber. The current work aims at developing a fast, accurate and operationally simple deep learning-based

Glucose is a widely used chemical, food and feedstock. 5-Hydroxymethylfurfural (5-HMF) is one of the platform molecules, which could be applied in chemical and fuel industries. This work presents the possibility of glucose and 5-HMF production from inedible cellulose, which is the main component of renewable plant (wood) biomass via one-pot hydrolysis–dehydration over solid acid catalysts based on

Methane (CH4) emissions from rice fields across China were estimated using the DNDC (DeNitrification-DeComposition) model. The results showed that the CH4 emissions from Chinese rice fields in 2012 were estimated to be 8.20 Tg CH4 yr−1 (ranging from 4.80 to 11.40 Tg CH4 yr−1); the values from early, late, and single cropping rice were 1.12, 2.86, and 4.23 Tg CH4 yr−1. Rice fields in AEZ (agricultural

The scale of herbicide resistance within a cropping region can be estimated and monitored using surveys of weed populations. The current approach to herbicide resistance surveys is time consuming, logistically challenging, and costly. Here we review past and current approaches used in herbicide resistance surveys with the aims of i) defining effective survey methodologies, ii) highlighting opportunities

The relationships of structural root depth, stem girdling roots, stem diameter, and boulevard width were studied on the condition of four tree species (Acer saccharum L., Celtis occidentalis L., Fraxinus pennsylvanica Marsh, and Tilia cordata Mill.) grown as street trees. The relationship between depth from the soil surface to the structural roots and development of stem encircling roots and stem girdling

The degradation and scarcity of floral resources represent one of the greatest threats to pollinators on a global scale. In a 2-year study, we aimed to assess the food resources in five members of Ranuculaceae family (Hepatica nobilis Mill., Anemone nemorosa L., A. ranunculoides L., Ranunculus cassubicus L., R. lanuginosus L.), which are common to the ground layer of the deciduous forest habitat in

Conventional centralized drainage systems are not only expensive, but their mono-function to discharge surface runoff also imposes a negative effect on the local environment while compounding regional watershed dysfunction. Sponge city initiative promoted by the Chinese government is a broader sustainable stormwater management concept that aims to use more nature-based solutions, reduce urban flooding

Urban parks have well-documented health benefits for urban residents. To increase the use of parks and enhance the physical activity level of city-dwellers, recent studies have explored the link between the amount of greenery in parks and the level of park usage. However, the results have been inconsistent, partly due to different measurements of park greenery. In this study, we developed a novel method

Wildfires are one of the major environmental concerns in Mediterranean ecosystems. Thus, many studies have addressed wildfire impacts on soil and vegetation in Mediterranean forests, but the linkages between these ecosystem compartments after fire are not well understood. The aim of this work is to analyze soil-vegetation relationships in Mediterranean burned forests as well as the consistency of these

There is an urgent need for quantifying the terrestrial carbon sink in the context of global carbon emissions. However, neither the flux measurements, nor the national wood balances fulfil this purpose. In this discussion article we point at various shortcomings and necessary improvements of these approaches in order to achieve a true quantification of the carbon exchange of land surfaces. We discuss

Education outside the classroom (EOtC) is a primary school educational approach that utilizes the school’s local environment for teaching purposes. The aims of this study are 1) to examine the provision and characteristics of regular EOtC (referred to as udeskole in Danish), in Denmark in 2019 and 2) to investigate trends in the extent of the practice of regular EOtC in Denmark from the first surveys

We review statistical approaches applicable for the analysis of data from binary mixture experiments, which are commonly used in pesticide science for evaluating antagonistic or synergistic effects. Specifically, two different situations are reviewed, one where every pesticide is only available at a single dose level and a mixture simply combines these doses, and one where the pesticides and their

The fall armyworm, Spodoptera frugiperda is a native species in the Americas. After first detected in western and central Africa in early 2016, it is one of the most serious invasive lepidopteran pests in many African and Asian countries. S. frugiperda has been spread very quickly. However, there were no molecular‐based simple and accurate diagnostic tools for this species identification in the field

Culex quinquefasciatus resistance to the binary toxin from Lysinibacillus sphaericus larvicides can occur because of mutations in the cqm1 gene that prevents the expression of the toxin receptor, Cqm1 α‐glucosidase. In a resistant laboratory‐selected colony maintained for more than 250 generations, cqm1REC and cqm1REC‐2 resistance alleles were identified. The major allele initially found, cqm1REC,

Wild pigs (Sus scrofa) cause widespread environmental and economic damage, and as a result are subjected to extensive control. Current management strategies have proven insufficient, and there is growing interest in use of toxicants to control invasive populations of this species. In 2017 a low‐dose warfarin bait was federally approved for use in controlling wild pigs in the U.S. However, no states

Although wood cross sections contain spatiotemporal information regarding tree growth, computer vision-based wood identification studies have traditionally favored disordered image representations that do not take such information into account. This paper describes image partitioning strategies that preserve the spatial information of wood cross-sectional images. Three partitioning strategies are designed

ABSTRACT Following the nuclear disaster of 1986, forests have established throughout the abandoned agricultural landscapes within Chernobyl Exclusion Zone (ChEZ). However, they are yet to be monitored properly. Their biometrical parameters need a robust assessment considering climate change mitigation potential and wildfire-induced risks. To predict basal area (BA) and growing stock volume (GSV) of

ABSTRACT Fungi play an important role in mediating soil functioning and plant nutrients absorption. Although nitrogen (N) addition and reduced precipitation can affect fungal community composition, the response of fungal taxonomic and functional groups to changes in soil N and water availability is still unclear. Here, we established a long-term field manipulations experiment of N addition and throughfall

Cuprous oxide nanoparticles (Cu2O NPs), phenol formaldehyde (PF) resin, and stearic acid (STA) were used to fabricate hierarchical core/shell structures to endow wood with superhydrophobic function, in which the preparation of Cu2O NPs and the synthesis of PF were carried out simultaneously in one system. The Cu2O NPs with the shape of a symmetrical tetrahexahedron were prepared in this work, and this

Quantitative studies on the water and nutrient enrichment of throughfall and stemflow in the Cerrado are lacking, especially among tree species. This work tested the hypothesis that the chemistry of rainfall fractions is altered after passing through the canopy and that the chemistry of stemflow can substantially change among tree species. We compared the nutrient concentrations in rainfall, throughfall

Purpose of Review Society is concerned about the long-term condition of the forests. Although a clear definition of forest health is still missing, to evaluate forest health, monitoring efforts in the past 40 years have concentrated on the assessment of tree vitality, trying to estimate tree photosynthesis rates and productivity. Used in monitoring forest decline in Central Europe since the 1980s,

The Sundarbans is a protected forest ecosystem in Bangladesh. A large number of people depend on this forest for their livelihoods and income. Many farmers in the region are now adopting fish farming—specifically, aquasilviculture (multi-purpose production system that allows production of fish and perennial plants mostly trees), one of the most profitable agroforestry systems in many countries. The

Rainfall partitioning by urban tree canopies plays an important role in urban hydrological cycles and, potentially, on stormwater runoff. While the body of research to quantify rainfall partitioning processes by urban trees is growing, there has not yet been a concerted effort to quantitatively synthesize these data. This meta-data analysis attempts such synthesis to deepen understanding of urban tree

Australia is currently grappling with a range of social and environmental challenges, many of which impact the way our public health system, and society more broadly, function. In this short communication paper we explore urban agriculture in Australia as a Nature-Based Solution (NBS) to address some of the ecological, social, economic and health challenges facing the continent. We argue that urban

Man-made landscaping materials form uppermost soil layers in urban green parks and lawns. To optimize effects of landscaping materials on biodiversity, plant growth and human health, it is necessary to understand microbial community dynamics and physicochemical characteristics of the landscaping materials during storage. In the current three-year study, the consequences of long-term storage on biotic
