This study examines whether regional infrastructure can predict economic resilience in European regions, focusing on resistance, recovery, and reorientation during the COVID-19 crisis. While infrastructure is widely recognized as a key factor influencing regional resilience, its explicit role has been underexplored in the European context. Using a comprehensive literature review and spatial econometric models applied to NUTS-2 level data from 2017 to 2024, we investigate the direct and spatial spillover effects of various infrastructure types—transportation, healthcare, tourism, education, and digital access—on regional resilience outcomes. We apply OLS and four spatial models (SEM, SLX, SDEM, SDM) under 29 spatial weighting matrices to account for spatial autocorrelation. Results show that motorway density, early school leaving, and healthcare infrastructure in neighbouring regions significantly affect resistance. For recovery, railway density and GDP per capita emerge as key predictors, with notable spatial spillovers. Reorientation is shaped by population structure, railway density, and tourism infrastructure, with both positive and negative spatial dynamics observed. The findings underscore the importance of infrastructure not only in isolation but also within regional systems, revealing complex interdependencies. We conclude that policymakers must consider spatial externalities and coordinate infrastructure investments to enhance regional economic resilience across interconnected Europe. Full article

Understanding the entrepreneurial profile is essential for developing effective regional policies that promote business growth. The path of an entrepreneur is shaped not only by individual decisions but also by the inherent risks of managing a business. This study aims to identify the characteristics of entrepreneurs at the regional level, specifically highlighting the impact of accumulated experience in their fields. Our central hypothesis asserts that entrepreneurial experience significantly influences how business owners perceive and respond to economic challenges. Utilizing survey data from 120 entrepreneurs in Romania’s Center Region (a NUTS 2 area), we reveal that entrepreneurial experience profoundly affects perceptions of key business challenges, such as legislative instability, taxation predictability, governmental support strategies, and access to SME financing. Importantly, our findings demonstrate that entrepreneurs with less than 10 years of experience express greater concerns about these challenges compared to their more seasoned peers. This novel insight highlights the need for tailored policy interventions aimed at enhancing regional economic resilience and fostering entrepreneurial sustainability. By addressing the specific needs of less experienced entrepreneurs, our study contributes to a deeper understanding of how experience shapes business dynamics in the region. Full article

Sustainable Development Reserves are organized units in the Amazon that are essential for the proper use and sustainable management of the region’s natural resources and for the livelihoods and economy of the local communities. This study aims to provide a climatic characterization of the Madeira River Sustainable Development Reserve (MSDR), offering scientific support to efforts to assess the feasibility of implementing adaptation measures to increase the resilience of isolated Amazon communities in the face of extreme climate events. Significant statistical analyses based on time series of observational and reanalysis climate data were employed to obtain a detailed diagnosis of local climate variability. The results show that monthly mean two-meter temperatures vary from 26.5 °C in February, the coolest month, to 28 °C in August, the warmest month. Monthly precipitation averages approximately 250 mm during the rainy season, from December until May. July and August are the driest months, August and September are the warmest months, and September and October are the months with the lowest river level. Cold spells were identified in July, and warm spells were identified between July and September, making this period critical for public health. Heavy precipitation events detected by the R80, Rx1day, and Rx5days indices show an increasing trend in frequency and intensity in recent years. The analyses indicated that the MSDR has no potential for wind-energy generation; however, photovoltaic energy production is viable throughout the year. Regarding the two major commercial crops and their resilience to thermal stress, the region presents suitable conditions for açaí palm cultivation, but Brazil nut production may be adversely affected by extreme drought and heat events. The results of this study may support research on adaptation strategies that includethe preservation of local traditions and natural resources to ensure sustainable development. Full article

The purpose of this study was to evaluate the energy and environmental potential of waste biomass in the form of hazelnut shells from selected Turkish varieties of Corylus avellana L. Eight commercial varieties (Çakıldak, Foşa, İnce Kara, Kalın Kara, Palaz, Tombul, Yassı Badem and Yuvarlak Badem) grown in different regions of the Black Sea coast of Turkey were analyzed. The scope of this study included whole nut and shell weight determination, technical and elemental analysis, higher heating value (HHV) and lower net heating value (LHV), as well as emission factors (CO, CO₂, NO_x, SO₂, dust) and flue gas composition based on stoichiometric calculations. The results showed a significant effect of varietal characteristics on all analyzed parameters. The share of shell in the total weight of the nut ranged from 43.5% (Tombul) to 55.3% (İnce Kara). HHV values ranged from 18.37 to 19.20 MJ·kg⁻¹, and LHV from 17.05 to 17.90 MJ·kg⁻¹. The İnce Kara and Yassı Badem varieties showed the most favorable energy properties. Elemental analysis confirmed a low nitrogen and sulfur content, which translated into low NO_x and SO₂ emissions. NO_x emissions were lowest for the Tombul variety (1.43 kg·Mg⁻¹), and SO₂ emissions were close to zero in each variety. The results confirm that Turkish hazelnut shells are a valuable energy resource and can be used as solid fuel or supplementary biomass. In particular, the İnce Kara variety was identified as the most promising due to its high shell weight, very good fuel properties, and high yield potential. This study underscores the importance of selecting the right variety to optimize agricultural waste utilization strategies within a circular economy. Full article

The walnut (Juglans regia L.) holds a significant position among Kazakhstan’s nut crops, both in terms of cultivation and consumption. Although genetic resources of walnut are accessible within the country, they remain underexplored, yet they represent a valuable foundation for breeding initiatives and the development of locally adapted varieties. Currently, a comprehensive genetic profile of these resources is lacking, which hampers their effective utilization. The aim of this research was to evaluate the genetic diversity within a collection of walnut accessions collected from the southern and southeastern regions of Kazakhstan, including Almaty and Turkestan regions. To achieve this, eight SSR molecular markers were employed, providing insights into the genetic structure and relationships among the germplasm. All markers exhibited a high degree of polymorphism, with the WGA276 locus standing out as the most informative, displaying the greatest number of alleles and a high Shannon diversity index. The average expected heterozygosity (He) was 0.704 and was significantly higher than the observed heterozygosity (Ho = 0.547), which was confirmed by t-test (t = −6.426, p < 0.05). The findings indicated substantial genetic variation and intra-population polymorphism: on average, 5.875 alleles per locus were identified, and the Shannon index was 1.444. The population from Turkestan region (population 1, Sairam-Ugam) demonstrated the highest levels of diversity. Analyses of genetic structure, conducted through STRUCTURE, PCoA, and UPGMA methods, confirmed the existence of two genetically distinct groups exhibiting considerable diversity. Future research should focus on conserving the highly diverse populations in the Turkestan region to facilitate the development of stress-tolerant varieties. These findings highlight the importance of conserving and harnessing the genetic resources of Kazakhstan’s J. regia populations for future breeding efforts. Full article

The growing demand for healthy and sensorially pleasing foods is accompanied by increasing sustainability concerns among consumers and industry. Therefore, exploring native and underutilized resources for traditional preparations is important. This study evaluated the incorporation of Moringa oleifera leaves and baru almonds (Dipteryx alata) in pesto sauce, comparing them to the traditional recipe regarding composition, color, total phenolics, volatiles, sensory characteristics, and acceptability. The following four formulations were developed: basil with cashew nuts (B/CN); basil with baru almonds (B/BA); and two versions with 50% basil replaced by moringa, combined with cashew (BM/CN) or baru (BM/BA). BM/BA presented the highest protein content (9.0%), compared to B/CN (7.9%). BM/CN showed a greener color. BM/CN and BM/BA showed total phenolics and antioxidant capacities similar to B/CN. BM/BA showed elevated condensed tannins (113.28 mg CE/100 g). All samples contained 1,8-Cineole and linalool, key to the aroma of basil. Pesto with moringa and/or baru showed good sensory acceptance, rated as “liked moderately”, with no difference from the conventional version (p > 0.05). There were no differences in the basil aroma, nutty flavor, or greasiness. Pesto sauce is a promising matrix for incorporating regional, underused ingredients such as moringa leaves and baru almonds, expanding their potential in new food development. Full article

The Amazon rainforest hosts a diverse array of forest types, including those where Brazil nut (Bertholletia excelsa) occurs, which plays a crucial ecological and economic role. The Brazil nut is the second most important non-timber forest product in the Amazon, a symbol of development and sustainable use in the region, promoting the conservation of the standing forest. Understanding the vertical structure of these forests is essential to assess their ecological complexity and inform sustainable management strategies. We used terrestrial laser scanning (TLS) to assess the vertical structure of Amazonian forests with the occurrence of Brazil nut (Bertholletia excelsa) at regional (Amazonas, Mato Grosso, Pará, and Amapá) and local scales (forest typologies in Amapá). TLS allowed high-resolution three-dimensional characterization of canopy layers, enabling the extraction of structural metrics such as canopy height, rugosity, and leaf area index (LAI). These metrics were analyzed to quantify the forest vertical complexity and compare structural variability across spatial scales. These findings demonstrate the utility of TLS as a precise tool for quantifying forest structure and highlight the importance of integrating structural data in conservation planning and forest monitoring initiatives involving B. excelsa.

Micro-enterprises are vital to the European economy, including in Croatia, where they make over 88% of the total number of businesses. Despite their significance, they face substantial energy vulnerability due to factors like small size, limited financial resources, and high energy costs. This paper investigates the determinants of energy vulnerability among Croatian micro-enterprises, employing a survey of 470 micro-enterprises. The study covers firms across all Croatian NUTS2 regions and ensures geographic and sectoral representativeness. Key findings reveal that enterprises with higher energy expenditures relative to revenue are most susceptible to energy vulnerability, which is aligned with our assumption. On the other hand, businesses that own their premises, have more employees, and have been operational longer are more likely to invest in energy efficiency measures, thereby reducing vulnerability. Notably, a significant proportion of micro-enterprises report that energy costs adversely affect their household finances, highlighting the nature of business and personal economic stability. The paper underscores the need for targeted policies and support mechanisms to enhance the energy-related resilience of micro-enterprises, considering their unique structural and financial constraints.

Areca nut/betel quid (AN/BQ), a stimulant consumed across the Asia and Pacific region, has been associated with metabolic risks including obesity. This study investigated the association between AN/BQ use and obesity in Guam. Participants included 120 men and women 18+ years old. Recruitment and interviews were conducted at a central dental clinic in Guam between July 2013 and October 2014. Multivariate general linear models were utilized to estimate the association of AN/BQ chewing with body mass index (BMI). Of the participants with a mean BMI of 30.4 (SD 6.9) kg/m², 82.5% reported ever chewing AN/BQ. The mean adjusted BMI among AN/BQ chewers was 4.53 kg/m² (95% CI 1.19, 7.87) higher than among non-chewers in the minimally adjusted model; 4.72 kg/m² (95% CI 1.09, 8.35) higher with additional adjustment for annual household income, tobacco smoking, and alcohol use (n = 108); and non-significantly higher by 0.55 kg/m² (95% CI −3.92, 5.02) after additional adjustment for ethnicity. Although AN/BQ chewing was not associated with BMI after considering ethnicity, our results do not exclude the possibility that AN/BQ chewing can be considered a risk factor for obesity.

Colletotrichum fructicola is a member of the gloeosporioides complex and can act as a pathogen, causing anthracnose in various plants and as an endophyte residing in healthy plants. As a plant pathogen, C. fructicola has been frequently reported to cause anthracnose in chili fruit and tea plants, bitter rot in apples and pears, crown rot in strawberries, and Glomerella leaf spot in apples, which are the most common diseases associated with this pathogen. Over the years, C. fructicola has been reported to infect a wide range of plants in tropical, subtropical, and temperate regions, including various types of fruit crops, ornamental and medicinal plants, tree nuts, peanuts, and weeds. Several reports have also been made regarding endophytic C. fructicola recovered from different plant parts. Endophytic C. fructicola has the ability to switch to a pathogenic state, which may contribute to the infection of host and other susceptible plants. Due to the economic importance of C. fructicola infections, the present review highlighted C. fructicola as a plant pathogen and endophyte, providing a summary of its infections in various plants and endophytic ability to inhabit plant tissues. Several control measures for managing C. fructicola infections have also been provided. Full article

Italy and Greece share many structural and economic similarities, including high regional disparities and marked asymmetries between dynamic metropolitan areas and structurally weaker regions. Both countries also face high public debt and an aging population, conditions worsened by recent economic crises. These challenges have significant implications for sustainability, as economic hardship often leads to inefficient resource use, underinvestment in green infrastructure, and socially unsustainable outcomes. Promoting socio-economic and environmental sustainability thus requires addressing territorial inequalities through integrated policies that balance growth, equity, and ecological responsibility. This study introduces a spatiotemporal application of the Peña Distance (DP2) method, allowing for a dynamic and multidimensional analysis of socio-economic deprivation at the NUTS 1 level. The results confirm persistent disadvantages in remote Greek regions and Southern Italy, where youth outmigration and limited development opportunities are prevalent. These regions are affected by multiple, interconnected forms of vulnerability that compromise their prospects for long-term sustainable development, underlining the need for timely and coordinated interventions across different policy levels.

This study explores the regional disparities in the tourism sector in Portugal between 2012 and 2022 with the aim of understanding how the spatial distribution, typology, and scale of tourism enterprises relate to regional wage dynamics. Using a quantitative approach, the analysis draws on secondary data from the Ministry of Labour and the Bank of Portugal, incorporating information on business characteristics and average employee remuneration across NUT II or regions. A combination of descriptive statistics, linear mixed-effects regression models, time series analysis, and ANOVA tests were employed to capture both temporal and territorial variations. The findings reveal a notable concentration of larger tourism enterprises in Lisbon, the North, and the Algarve, coupled with persistent wage disparities that tend to favour these same regions. Although average wages have increased, they remain insufficient in areas with high living costs, raising concerns about tourism’s redistributive potential. The study provides empirical evidence that tourism may exacerbate rather than reduce regional inequalities. By highlighting the territorial dimension of economic outcomes, this research offers valuable insights for policymakers and contributes to a more nuanced theoretical understanding of tourism-led development.

Xyloglucan endotransglucosylases/hydrolases (XTHs) are key enzymes involved in cell wall remodeling by modifying xyloglucan–cellulose networks, thereby influencing plant growth, development, and secondary cell wall formation. While the roles of XTHs have been extensively studied in primary and secondary growth, their functions in the formation and thickening of lignified nut shells remain largely unknown. Pecan (Carya illinoinensis), an economically important nut crop, develops a hard, lignified shell that protects the seed during fruit maturation. In this study, we performed a comprehensive genome-wide characterization of the XTH gene family in pecan and identified 38 XTH genes, which were categorized into four distinct phylogenetic groups. Structural analyses of the deduced proteins revealed conserved catalytic residues alongside divergent loop regions, suggesting functional diversification. Expression profiling across various tissues and among pecan cultivars with contrasting shell phenotypes indicated that specific XTH genes may play critical roles in shell structure formation. Moreover, gene regulatory networks in thin- and thick-shelled pecans provided new insights into the molecular mechanisms underlying shell development and thickness regulation. These findings lay a foundation for future genetic improvement strategies targeting nut shell traits in woody perennials. Full article

Understanding alcohol consumption patterns is critical for developing effective public health strategies, particularly in countries like Spain where cultural and regional drinking norms vary widely. This study examined sociodemographic factors affecting alcohol consumption patterns across Spain, employing a cross-sectional design. A total of 22,181 Spanish adults over 18 years of age were recruited between August 2020 and November 2021, using non-probabilistic snowball sampling through social media networks. Data were gathered via a validated questionnaire (NutSo-HH Scale) encompassing sociodemographic details, health indicators, and lifestyle habits, with a focus on alcohol use. The sample included n = 22,181 participants, 80.8% women, with a mean age of 34.9 years. Most respondents (48.2%) reported no or very occasional alcohol consumption, 33% drank 2–4 times per month, 13.8% consumed alcohol 2–3 times weekly, and 5% drank daily or nearly daily. Alcohol consumption was significantly higher among men (72.1% consuming fermented beverages) and individuals with higher income and education (p < 0.001 for all variables). Regional differences were also notable, with the highest percentage of regular drinkers in Asturias (80.9%) and the Valencian Community (73.3%) as revealed by a Kruskal–Wallis test (p < 0.001). Fermented beverages were the most popular, with 68.4% of alcohol consumers preferring these, compared to distilled beverages (18.8%), fortified beverages (15.1%), and liqueurs (3.3%). A Gaussian graphical model was used to explore conditional relationships between alcohol consumption and other beverages in the Spanish population. Alcohol showed strong positive associations with fermented and distilled beverages, and with the habit of getting drunk. Weaker negative correlations were observed with water and soft drinks, suggesting contrasting consumption patterns. These findings underscore significant sociodemographic and regional variations in alcohol consumption patterns across Spain, suggesting the need for public health interventions tailored to different population segments.

Decarbonizing the transportation sector is critical for sustainable development, particularly in rapidly urbanizing countries like Turkiye. This study analyzes fuel demand elasticities for diesel, gasoline, and LPG across 12 NUTS-1 regions of Turkiye in 2022, using a panel random effects SUR approach. The model accounts for regional variation and fuel interactions, producing robust estimates that uncover significant spatial and temporal differences in consumption patterns. Uniquely, diesel demand displays a significantly positive price elasticity, challenging the conventional assumption of inelasticity. Gasoline demand is moderately price-sensitive, while LPG appears relatively unresponsive. Strong cross-price elasticities—especially between diesel and gasoline—point to substitution effects that can inform more adaptive policy frameworks. Seasonal fluctuations and Istanbul’s outsized impact also shape national trends. These findings underscore the need for differentiated region- and fuel-specific strategies. While higher gasoline taxes may effectively reduce demand, lowering diesel and LPG use will require complementary measures such as infrastructure upgrades, behavioral incentives, and accelerated adoption of alternative fuels. The study advocates for regionally adjusted carbon pricing, removal of implicit subsidies, and targeted support for electric and hybrid vehicles. Aligning fiscal tools with actual demand behavior can enhance both the efficiency and equity of the transition to a low-carbon transportation system. Full article
