First Report of Fomitopsis Marianiae as a Causal Agent of Brown Wood Rot in Hazelnut (Corylus Avellana) Worldwide
(John Wiley and Sons Inc, 2026) Türkkan, M.; Özer, G.; Bozoglu, T.; Erper, İ.; Derviş, S.
Hazelnut (Corylus avellana L.) is a cornerstone of Türkiye's agricultural economy, accounting for over 60% of global production. In 2022, a wood decay disease was observed in orchards of Samsun Province, affecting 3% (15 of 500) of surveyed trees. Symptoms included branch dieback and canopy chlorosis, while internal inspection revealed extensive brown rot of the xylem. Fungal isolates consistently produced white, fast-growing colonies with clamp connections. Multilocus sequencing of the internal transcribed spacer (ITS), large subunit (LSU) and small subunit (SSU) ribosomal DNA regions, and the partial translation elongation factor 1-alpha (tef1) gene identified the pathogen as Fomitopsis marianiae. Phylogenetic analysis of ITS + tef1 datasets placed the Turkish isolate within the F. marianiae clade. Pathogenicity was confirmed by inoculating 1-year-old hazelnut seedlings, which developed necrotic lesions averaging 3.88 ± 0.22 cm within 3.5 months; the fungus was successfully reisolated, fulfilling Koch's postulates. This study represents the first report of F. marianiae as a pathogen of hazelnut and, more broadly, its first documentation in any agricultural system. These findings identify F. marianiae as an emerging threat to a globally important nut crop and highlight the need for targeted disease surveillance and management strategies. © 2026 Wiley-VCH GmbH.

Operationalizing Smart Service Experience: Guest Engagement, Value, Memories, and Behavioral Intentions in Hotels
(Elsevier Ltd, 2026) Ali, F.; Şener, G.; Petkovic, Z.; Cavusoglu, M.; Alotaibi, S.
This study investigates the impact of Smart Service Experience (SSE) on guest engagement, memories, smart service value, and behavioral intentions in the hotel industry. Drawing on the Stimulus-Organism-Response (SOR) theory, the study explores how smart technologies, such as AI-powered room customization and digital concierge services, influence guest perceptions and their subsequent behaviors. Data collected via Amazon mTurk from 244 hotel guests who recently experienced SSE was subjected to Partial Least Squares based Structural Equation Modeling (PLS-SEM). Results reveal that SSE positively influences engagement, which in turn affects memories and perceived value. These outcomes contribute to guests’ loyalty, revisitation intentions, and word-of-mouth recommendations. This paper is the first to operationalize the concept of SSE in the context of smart hotels, offering novel empirical insights into how SSE influences guest engagement, memories, perceived service value, and long-term behavioral intentions such as loyalty and revisitation. © 2026 The Authors
Mechanistic Insights Into the Anticancer Effects of Lavandula Stoechas L. Via Apoptosis and Autophagy Regulation
(Elsevier B.V., 2026) Tukenmez Emre, U.; Nigdelioglu Dolanbay, S.; Şirin, S.; Aslím, B.
This study aimed to evaluate the chemical composition and antioxidant, genotoxic, antigenotoxic, and anticancer properties of the methanolic extract of Lavandula stoechas L. (LSME). Total flavonoid content was determined spectrophotometrically, and total phenolic content was measured using Folin–Ciocalteu reagent. The phenolic compounds were identified and quantified by high-performance liquid chromatography (HPLC). The antioxidant activity was assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, metal chelation, and plasma lipid peroxidation assays. Genotoxicity/antigenotoxicity was evaluated using the comet assay, and cytotoxicity was determined using the MTT assay in MCF-7, SK-BR-3, and MCF-12A cell lines. Gene expression related to apoptosis, autophagy, and the AMPK/mTOR signaling pathway was analyzed using quantitative real-time PCR (qRT-PCR). Phytochemical analysis revealed that LSME is rich in phenolics (294.6 mg/g) and flavonoids (7.50 mg/g). HPLC profiling identified 23 phenolic constituents, with rosmarinic acid, chlorogenic acid, and luteolin as the predominant compounds. LSME exhibited strong antioxidant activity in all assays. Genotoxicity assays showed no significant DNA damage, while antigenotoxicity assays demonstrated a protective effect against H₂O₂-induced DNA damage in human lymphocytes. In vitro cytotoxicity assays revealed dose-dependent antiproliferative effects in MCF-7 and SK-BR-3 cells, without cytotoxicity toward normal breast epithelial cells (MCF-12A). Molecular analyses indicated activation of intrinsic apoptotic and autophagic pathways and modulation of the AMPK/mTOR signaling axis. Molecular docking supported interactions between major phenolic compounds and key target proteins. These findings demonstrating that LSME exerts selective anticancer effects in HER2+ and HER2- breast cancer cells and highlighting its potential as a plant-based therapeutic candidate. © 2026 SAAB
Sex-Based Differences in Triacylglycerol and Phospholipid Subclasses of Gonadal Fatty Acids in the Freshwater Fish Capoeta Umbla
(Japan Oil Chemists Society, 2026) Kaçar, S.; Kaya, H.K.; Başhan, M.
The extraction and separation of polar, triacylglycerol (TAG) and phospholipid (PL) subclasses—phosphatidylcholine (PC), phosphatidylserine (PS), Lipid subclasses phosphatidylinositol (PI), and phosphatidylethanolamine (PE)— were carried out in the gonads to determine fatty acid (FA) compositions using gas chromatography. The major FAs identified in the ovary and testis were palmitic acid (16:0), stearic acid (18:0), oleic acid (18:1n9), arachidonic acid (20:4n6, AA), eicosapentaenoic acid (20:5n3, EPA), docosapentaenoic acid (22:5n3), and docosahexaenoic acid (22:6n3, DHA). In the PL fraction, the proportions of saturated fatty acids (∑SFAs), monounsaturated fatty acids (∑MUFAs), and palmitoleic acid (16:1n7) were higher in the ovary than in the testis, whereas EPA, polyunsaturated fatty acids (∑PUFAs), and the n3/n6 ratio were higher in the testis than in the ovary. In the TAG fraction, ovaries contained higher levels of 16:0 and ∑SFA, whereas the testes contained higher levels of ∑PUFA. This result indicates that ovaries were more dominant in saturated fatty acids and testes are more dominant in polyunsaturated fatty acids. © ©2026 by Japan Oil Chemists’ Society.

(Elsevier Ltd, 2026) Ercan, L.; Calıskan, C.G.
Verbascum andrusii is an endemic species that grows in the Southeastern Anatolia Region. This study sought to figure out the total amount of phenolic molecules, the total amount of carotenoids, phenolic compounds, volatile compounds, antioxidant and antimicrobial activity, the inhibition effect on xanthine oxidase and elastase enzymes of V. andrusii, and to examine its cytotoxic effect on A549 (lung carcinoma) cells. For this, V. andrusii's volatile and phenolic components were analyzed employing the HS-SPME technique and UHPLC-Orbitrap®-HRMS, respectively. Additionally, the antibacterial behavior by the disc diffusion method and the in vitro antioxidant capacity by four distinct techniques (DPPH, ABTS, CUPRAC, and DMPD) were assessed. Furthermore, the inhibitory effect of its on the enzymes elastase and xanthine oxidase was assessed both in vitro and in silico. Pharmacokinetic features and activities of bioactive components of V. andrusii were assessed in silico by ADME/T, molecular docking, and density functional theory (DFT). As a result, it was revealed that V. andrusii showed a cytotoxic effect on A549 cells (IC50: 130.40 μg/mL) and had antioxidant, antimicrobial (on the microorganisms E. coli, K. aerogenes, P. aeruginosa, C. albicans, S. aureus, and K.pneumoniae), antiaging (antielastase IC50: 450.10 μg/mL), and antihyperuricaemia (antixanthinoxidase IC50: 239.02 μg/mL) properties. In addition, the effect of the components of this plant on the biological properties of the plant was evaluated by in silico studies. It was concluded that in silico investigations of diosmetin, luteolin, luteolin 7-rutinoside, apigenin, quinic acid, benzoic acid, anethole, and D-limonene, which are the main components of V. andrusii, confirmed the experimental studies. © 2026 Elsevier Ltd
Assessment Of Genetic Diversity Among Fusarium Species Isolated from Wheat Using SCoT Markers
(Namik Kemal University - Agricultural Faculty, 2026) Özer, G.; Yeken, M.; Derviş, S.; Palacıoğlu, G.
Fusarium species pose significant threats to wheat cultivation by inducing root rot, crown rot, and head blight. Understanding the genetic variations within these species is pivotal for effective disease management strategies. This investigation aimed to evaluate the genetic variation among isolates of Fusarium culmorum, F. graminearum, and F. pseudograminearum following their identification via cultural and species-specific PCR assays. The application of species-specific PCR facilitated the precise identification of these species by generating bands of distinct sizes (F. culmorum: 570 bp, F. pseudograminearum: 520 bp; F. graminearum: 420 bp), aligning with morphological classifications. A total of 36 Start Codon Targeted (SCoT) markers were employed to characterize the genetic variability among Fusarium isolates. Among the selected SCoT primers, 181 bands were amplified, with 131 exhibiting polymorphism (72.37%). The percentages of polymorphic bands in primers varied between 61.54 and 89.29. The highest polymorphism locus was observed in Fusarium culmorum with 12.71%, followed by F. pseudograminearum and F. graminearum. The average polymorphism information content and resolving power for the SCoT markers were calculated as 0.26 and 10.04, respectively. Utilizing the unweighted pair group method with arithmetic mean (UPGMA) clustering analysis employing Dice's method, the SCoT data delineated the Fusarium isolates into three distinct clusters corresponding to species. The study which focused on specifically evaluating the genetic diversity of Fusarium culmorum, F. graminearum and F. pseudograminearum, recognized as primary threats to global wheat cultivation, with SCoT markers, substantial genetic variations were revealed among Fusarium isolates at both inter-and intra-species levels. This investigation represents the initial endeavor to elucidate the genetic diversity of Fusarium isolates obtained from wheat utilizing SCoT markers. © 2026, Namik Kemal University - Agricultural Faculty.

Hybrid Machine Learning Approach for Enhanced Fault Detection and Power Estimation in Photovoltaic Systems
(John Wiley and Sons Inc, 2026) Alpsalaz, F.; Özüpak, Y.; Aslan, E.; Uzel, H.
Accurate power prediction and fault detection in photovoltaic (PV) systems are essential for improving energy efficiency and enabling predictive maintenance. This study proposes a novel hybrid regression model based on a stacking ensemble architecture, which integrates multiple machine learning algorithms: histogram-based gradient boosting (HGB), k-nearest neighbors (k-NN), decision tree (DT), random forest (RF), and LightGBM as base learners and employs Ridge regression as the meta-learner. The model was designed to detect complex fault conditions such as partial shading and module-level failures using SCADA-type input features. The performance of the proposed model was evaluated using standard regression metrics (R2, RMSE, MAE), achieving superior results with an R2 of 0.9939, RMSE of 12.0184, and MAE of 8.0544. Paired t-tests confirmed the statistical significance of performance improvements over baseline models (p < 0.05). To ensure transparency, explainability analyses were conducted using SHapley Additive exPlanations (SHAP) and local interpretable model-agnostic explanations (LIME), which revealed that fault-related features had the greatest influence on model predictions. Comparative evaluation with recent state-of-the-art approaches demonstrated that the proposed hybrid model is scalable, computationally efficient, and robust under varying environmental and operational conditions. The findings suggest that the model can serve as a reliable and interpretable solution for real-time power forecasting and fault detection in PV systems. © 2026 The Author(s).

(AVES, 2026) Aktar Karakaya, A.A.; Unal, E.; Yıldırım, R.; Özalkak, Ş.; Taş, F.F.; Özbek, M.N.
Objective: Turner syndrome (TS) is the most common sex chromosome abnormality in girls. Short stature is the most distinctive feature. This study aimed to evaluate factors affecting final height (FH) in patients with TS who received growth hormone (GH) therapy and achieved their final height (FH). Materials and Methods: About 48 patients with TS who received GH therapy and reached their FH were included and examined retrospectively. Initial height, standard deviation score (SDS), FH, and FH SDS measurements of the patients were obtained. Additionally, factors affecting FH were analyzed. Results: Growth hormone was administered at a dose of 45.6 ± 6.2 (min-max: 34-69) μg/kg/day at a mean age of 11.7 ± 2.9 years. The duration of therapy was 4.3 ± 1.4 years. The mean FH of the patients was 147.80 ± 5.98 cm. About 29.2% (n=14) of the patients reached a height above the thirdpercentile. It was observed that GH therapy was initiated in these patients at a mean age of 10.3 ± 3.1 years; the initial height SDS was better. FH of 45,X and non-45,X cases were similar. Conclusion: In the study, GH therapy that was initiated at an early age in patients with good initial height SDS increased the gain of FH and FH SDS. Therefore, initiating GH therapy at an early age in patients with TS is important for height gain. ∆ Height SDS was better in cases that underwent late pubertal induction. Karyotype did not have a predictive effect on height prognosis. © 2026, AVES. All rights reserved.
Occurrence of Fusarium Ananatum on Marketed Pineapples: First Report of Fruitlet Core Rot and Crown Rot in Türkiye
(John Wiley and Sons Inc, 2026) Türkkan, M.; Bozoglu, T.; Özer, G.; Alkan, M.; Derviş, S.
Pineapple is an increasingly important tropical fruit crop in Türkiye; however, its quality is threatened by significant postharvest diseases. In June 2025, symptomatic pineapples were observed in central retail markets in Ordu Province, Türkiye. To identify the causal agent of the observed fruit and crown decay, affected fruits displaying distinct crown necrosis, bract browning, and cottony white to cream mycelial growth were collected. A fungus was consistently isolated from these tissues, producing floccose white colonies and fusiform macroconidia typical of the Fusarium fujikuroi species complex (FFSC). For molecular identification, partial sequences of the translation elongation factor 1-alpha (tef1) and RNA polymerase II second-largest subunit (rpb2) genes were analysed. The results confirmed that the Turkish isolates clustered with Fusarium ananatum isolates with high bootstrap support. Pathogenicity was confirmed using the toothpick inoculation method on fruits and detached crown leaves. These assays successfully reproduced the characteristic symptoms of fruitlet core rot and crown rot, and the pathogen was re-isolated, fulfilling Koch's postulates. This study constitutes the first report of F. ananatum in Türkiye. These findings highlight the emergence of this pathogen in the Mediterranean region and emphasise the urgent need for stringent phytosanitary monitoring to safeguard fruit quality and prevent postharvest losses in the domestic market. © 2026 Wiley-VCH GmbH.

Emergence of Severe Stemphylium Leaf Blight on Leek (Allium Porrum) During Seed Production in Türkiye
(John Wiley and Sons Inc, 2026) Polat, Z.; Beşirli, G.; Gültekin, M.A.; Derviş, S.; Özer, G.
A severe leaf blight epidemic caused by Stemphylium vesicarium was observed on cultivated leek (Allium porrum L.) in a commercial seed production field in Türkiye. The disease occurred in early summer 2025 during the second year of a biennial seed production cycle, where incidence reached 50%–75%. The extended cultivation period characteristic of seed production (12–18 months) likely served as a key epidemiological driver, enabling pathogen overwintering and extensive inoculum accumulation, in contrast to the shorter cropping period of annual vegetable production systems. The pathogen was identified as S. vesicarium based on morphological features and confirmed by maximum likelihood phylogenetic analysis of combined internal transcribed spacer (ITS) and glyceraldehyde-3-phosphate dehydrogenase (gapdh) gene sequences. Pathogenicity was verified through fulfilment of Koch's postulates using two representative isolates on healthy leek plants. This report constitutes the first confirmed occurrence of S. vesicarium on leek in Türkiye and demonstrates a shift in its epidemiological importance from a minor foliar pathogen in annual systems to the causal agent of a severe epidemic under biennial seed production conditions, highlighting the need for targeted surveillance and management strategies to mitigate disease risk in both seed and commercial leek production. © 2026 Wiley-VCH GmbH.

(Elsevier, 2025) Atay-Polat, M.; Arslan, F.
The aim of this study is to examine the impact of green finance on environmental quality. In this context, a panel of data covering 21 developing countries has been created. This data set includes carbon dioxide (CO2) emissions, green finance (GF), the share of renewable energy in total energy consumption (REN), per capita GDP (GNI) and international capital flows (FINANCE) to developing countries. The Panel Cantile Regression model was used to evaluate the relationship between the variables included in the analysis. The findings suggest that there is a long-term relationship between the variables. According to the cantile regression results, it has been observed that green finance has a negative impact on CO2 emissions, but this effect varies according to income levels. It has also been found that renewable energy improves environmental quality. © 2025 Elsevier Inc.

Acoustic-Based Fault Diagnosis of Electric Motors Using Mel Spectrograms and Convolutional Neural Networks
(Nature Portfolio, 2025) Uzel, Hasan; Ozupak, Yildirim; Alpsalaz, Feyyaz; Aslan, Emrah; Zaitsev, Ievgen
This study presents a comprehensive deep learning framework for diagnosing acoustic faults in electric motors. The framework uses Mel spectrograms and a lightweight convolutional neural network (CNN). The method classifies three motor states, engine_good, engine_broken, and engine_heavyload, based on audio recordings from the IDMT-ISA-ELECTRIC-ENGINE dataset. To prevent data leakage and ensure a robust evaluation, the study employed file-level splitting, session separation, 5-fold cross-validation, and repeated trials. The raw audio signals were transformed into Mel spectrograms and processed through a CNN architecture that integrates convolutional, pooling, normalization, and dropout layers. Quantitative metrics, including THD, spectral entropy, and SNR, further characterize the acoustic distinctions between motor states. The proposed model achieved a test accuracy of 99.7%, outperforming or matching state-of-the-art approaches, such as ResNet-18, CRNN, and Transformer classifiers, as well as traditional MFCC-based baselines. Noise robustness and sensitivity analyses demonstrated stable performance under varying SNR conditions and preprocessing settings. Feature-importance maps revealed that low-frequency regions (0-40 Mel bins) were key discriminative components linked to physical fault mechanisms. Computational evaluation confirmed the model's real-time feasibility on embedded hardware with low latency and a modest parameter count. Though primarily validated on one motor type, external-domain testing revealed strong adaptability. Future work may incorporate transfer learning or multimodal fusion. Overall, the proposed framework provides a highly accurate, interpretable, and efficient solution for real-time motor fault diagnosis and predictive maintenance in industrial environments.
Associations of Dietary Omega-3 and Omega-6 Fatty Acids, Obesity, and Psychological Stress With Fatigue in Patients With Chronic Obstructive Pulmonary Disease: A Cross-Sectional Study
(MDPI, 2026) Selen, Halime; Atabek, Beste; Gegez, Berfin; Sag, Aysenur; Gulbahar, Burcu Nur; Dogdu, Ibrahim Ethem; Akgun, Metin
Background/Aim: Fatigue is a common symptom in individuals with chronic obstructive pulmonary disease (COPD) and is associated with reduced quality of life. The aim of this study was to evaluate the relationships between dietary omega-3 (n-3) and omega-6 (n-6) fatty acid intake, obesity, and stress with fatigue in patients with COPD. Materials and Methods: This descriptive cross-sectional study was conducted between 1 February and 31 July 2025, in the pulmonary outpatient clinics of A & gbreve;r & imath; Training and Research Hospital in A & gbreve;r & imath; and Atat & uuml;rk University Research Hospital in Erzurum, T & uuml;rkiye. Study data were collected using a General Information Questionnaire, the COPD and Asthma Fatigue Scale (CAFS), the Perceived Stress Scale (PSS), and an Adult Semi-Quantitative Food Frequency Questionnaire. Higher CAFS scores indicate greater fatigue severity, while higher PSS scores reflect higher perceived stress. Results: CAFS scores correlated strongly with perceived stress (r = 0.718, p < 0.001) and moderately with COPD exacerbation frequency (r = 0.426, p < 0.001). Although higher n-3 intake was inversely associated with fatigue in univariate analyses, this association weakened after adjustment, suggesting that fatty acid composition was not an independent determinant of fatigue. The n-6/n-3 ratio showed a weak positive correlation with fatigue (r = 0.184, p = 0.024). Female reported higher fatigue levels than male (mean [SD], 60.2 [19.3] vs. 51.9 [19.8]; p = 0.042), and patients with comorbid conditions had higher fatigue scores than those without comorbidities (58.1 [18.3] vs. 46.8 [19.4]; p = 0.001). Smoking status was not significantly associated with fatigue (p = 0.788). In backward multiple linear regression analysis, perceived stress emerged as the strongest independent predictor of fatigue (beta = 0.519, p < 0.001). Comorbidity presence (beta = 0.206, p = 0.030) and smoking status (beta = 0.178, p = 0.026) were also significant, while exacerbation frequency (p = 0.062) and female (p = 0.053) showed borderline associations. Conclusions: These findings indicate that fatigue in COPD is primarily influenced by psychosocial stress and multimorbidity, highlighting the importance of integrative management approaches that address mental health burden and comorbid conditions alongside respiratory treatment.
GC–MS and LC–MS/MS-Based Phytochemical Profiling and Bioactivities of Salvia Montbretii and S. Hydrangea: Antioxidant, Cytotoxic and Enzyme Inhibitory Potential
(John Wiley and Sons Ltd, 2026) Kolak, U.; Cavusoglu, M.; Akdeniz, M.; Yener, I.; Yılmaz, P.; Fırat, M.; Ertaş, A.
Salvia species are valuable natural resources due to their rich essential oils and bioactive compounds with applications in medicine, food, and cosmetics. In this study, essential oils and aroma components of S. montbretii and S. hydrangea were analyzed using GC–MS/FID and headspace GC–MS. Terpenoids were identified by GC–MS, while phenolic and flavonoid compounds were quantified by LC–MS/MS. Total phenolic and flavonoid contents, antioxidant capacities, and enzyme inhibitory activities were also evaluated. Caryophyllene was the dominant compound in S. montbretii essential oil and aroma samples, and camphor in S. hydrangea. GC–MS results indicated high levels of ursolic (54,675.22–1583.23 μg/g) and oleanolic acids (100,567.85–2592.11 μg/g), while LC–MS/MS revealed abundant rosmarinic acid (up to 27,0857–587.85 μg/g). All extracts exhibited moderate to strong antioxidant activities and notable inhibitory effects against urease and cholinesterase. Cytotoxic effects were observed on colon (Caco-2) and ovarian (SkOV3) cancer cell lines, along with toxicity in healthy cells (PDF). In conclusion, S. montbretii and S. hydrangea may serve as potential natural sources for pharmaceutical and cosmetic applications; however, detailed safety and dosage assessments are required prior to practical use due to the observed cytotoxic effects. © 2026 John Wiley & Sons Ltd.

(Elsevier, 2026) Baran, Ayse; Baran, Mehmet Firat; Yildiz, Resit; Eftekhari, Aziz; Ozkan, Ahmet Ismail; Kesharwani, Prashant
Selenium nanoparticles are highly valuable materials. A multitude of methods is available for obtaining these items. Green synthesis methods are attracting significant attention, and due to the therapeutic characteristics of selenium, these advantageous compounds will become more prominent. This study entailed the rapid, uncomplicated, and cost-effective production of selenium nanoparticles (Se NPs) employing the herb "evelik" from Eastern Anatolia. The properties of the synthesized Se NPs were examined using Ultraviolet-Visible Spectroscopy (UV-Vis), Fourier-transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Scanning Transmission Electron Microscopy (STEM), X-ray Diffraction (XRD), and Energy-Dispersive X-ray Spectroscopy (EDX). Se nanoparticles, mostly spherical in shape, demonstrated a peak absorbance wavelength of 230 nm and a crystalline dimension of 62.7 nm. Their antibacterial effectiveness against pathogenic strains was evaluated using microdilution methods. The application demonstrated efficacy against Candida albicans ATCC 10231, Staphylococcus aureus ATCC 25923, and Escherichia coli ATCC 11229 within a dose range of 2.00-8.00 mu g mL- 1. Se NPs were analyzed on Prostate Carcinoma cells and Retinal Pigment Epithelial cells via the Methylthiazol Tetrazolium assay. The anticancer impact was shown to be substantial at a concentration of 62.5 mu g mL- 1, exhibiting a rate of 79.78%.
How Do Crop And Livestock Production Affect Carbon Emissions? Empirical Evidence From Türkiye
(Turkish Journal of Agricultural Economics, 2025) Kartal, N.; Bayar, İ.; Dabakoğlu, T.M.; Doru, Ö.
Purpose: The main purpose of this study is to reveal the role of agricultural activities on environmental quality by analysing the effects of renewable energy use, trade openness, gross domestic product and crop and livestock production on CO2 emissions in Türkiye for the period 1980-2022. Design/Methodology/Approach: In the study, the ARDL bounds test approach, known for providing reliable results even in small samples, is employed to examine the factors affecting CO2 emissions and to reveal the model’s short and long-run relationships. During the analysis process, the stationarity of the variables is first evaluated with ADF and PP tests, and then long-term relationships is determined. The reliability of the model is verified with various diagnostic tests, and the effects of the variables on CO2 emissions is revealed. Findings: The ARDL test results indicate that there is a long-run cointegration relationship between the variables. According to the calculated long-run coefficient results, renewable energy consumption, crop production and livestock production have a decreasing effect on CO2 emissions. On the other hand, gross domestic product and urbanisation are determined as factors that increase CO2 emissions. Originality/Value: It is noteworthy that studies on the impact of crop and livestock production on CO2 emissions in Türkiye are limited. It is estimated that the inclusion of factors such as renewable energy, GDP per capita and urbanisation in the model will provide a projection for both the literature and policy recommendations for improving environmental quality in Türkiye. © 2025, Turkish Journal of Agricultural Economics.

2023–2024 Excavations at Boğaziye Höyüğü: a Recently Discovered Mound Settlement in the Upper Khabur Region
(Istanbul University, 2025) Genç, B.; Şahin, M.; Işık, S.; Abakay, A.; Kaya, Ş.; Konyar, E.; Tan, A.
Boğaziye Höyüğü lies at the northwestern end of the vast and fertile Upper Khabur Region, which stretches along the southern foothills of the Kašiari Mountains. Material culture remains unearthed at the mound by two seasons of excavations (2023–2024) shows significant similarities to assemblages known from other Upper Khabur sites. Our excavations in Trenches BE18–BE17 and BF18 on the northern slope of the mound focused on revealing the stratigraphic sequence in this area. Architectural remains of Building Levels I and II and finds from these contexts in Trench BE18 are dateable to the mid-3rd millennium BC. In Trench BE17, Building Level I also revealed finds that can be dated to the 3rd (especially mid-3rd) millennium BC, and in Trench BF18, ceramic sherds dateable to the 3rd millennium BC were found in Building Level III. This article presents new findings from Boğaziye Höyüğü and discusses their significance in comparison with the results of surveys and excavations in the Upper Khabur Region, which have continued increasingly since the mid-1930s. We evaluate the significance of Boğaziye Höyüğü as a regional center within the Upper Khabur basin, and we elucidate its habitation sequence and building levels in the light of our recent excavations. Based on a comparative evaluation of its material culture remains within a regional perspective, we contextualize Boğaziye Höyüğü in relationship to the cultural horizons of the early and mid-3rd millennium BC in the Upper Khabur Valley. © 2025.

A Methodological Approach To Redefining Spatial Relations as a Result of Archaeological Excavations: Dara
(University of L'Aquila, Department of Civil Construction, Building and Architecture, Environmental Engineering, 2025) Simsek, D.; Kutlu, I.
Spatial relationships play a fundamental role in the emergence, development, and transformation of cities. Especially in the context of ancient cities, the relation and spatial hierarchy between the locations of spaces such as necropolis, agora, forum, acropolis and living spaces reveal the functional distinction of spaces. Some ancient cities were discovered as a result of excavations in rural or isolated areas far from settlements, while others were found just below or within actively inhabited residential areas. The ancient city of Dara-Anastasiopolis, one of the most significant settlements in Mesopotamia, is an interesting study area for analysing and explaining these relationships. This study aims to examine the transformation of the spatial relationships between the ancient city of Dara and the present rural settlement before and after the excavations. The study consists of a five-stage process involving a systematic literature review, fieldwork, data generation, modelling, space syntax analysis, and evaluation. The findings reveal that spatial relations transformed significantly after the excavations uncovered the ancient city. After the excavations, a new relational network emerged with the exposed spaces, and it has been determined that this new situation affects pedestrian and vehicle circulation. As a result, the study provides a unique contribution to the literature by providing a basis for the digital representation and management of cultural heritage sites in rural areas and analysing spatial relationships with data-based and interdisciplinary methods. © 2025 University of L'Aquila, Department of Civil Construction, Building and Architecture, Environmental Engineering.
