  Güvendı, Engın; Kahyaoğlu, Nuray; Ertuğrul, Murat Han

  Forests have been one of the most valuable resources for human survival and meeting needs from the beginning of life to the present day. Even the smallest intervention in forests can affect all living things. Therefore, forest crimes are an important issue that needs to be addressed in terms of the sustainable management of natural and forest resources. In this study, forest crimes, crime types, and the distribution of these crimes within the Trabzon Regional Forestry Directorate (OBM) and its affiliated Forestry Management Directorates (OİM) between 1997 and 2025 were examined. According to the research findings, a total of 15,879 crimes were committed in Trabzon OBM during the relevant period, of which 9131 were cutting, 2664 were clearing, 1464 were occupation, 1214 were possession, 755 were transportation, 337 were consumption, 112 were grazing, 115 were arson, 2 were hunting, and 1 was mining. The results show that the most common types of crime in Trabzon Forestry Directorate and its affiliated Forest Management Units are logging, clearing, and illegal occupation, while grazing, arson, mining, and hunting crimes remain at low levels. In conclusion, the types of crimes committed in forest areas within the jurisdiction of the Trabzon Regional Directorate of Forestry and its affiliated Forest Management Directorates, as well as the causes of these crimes, have been comprehensively evaluated; based on the findings, various recommendations have been developed to reduce the frequency of these crimes.

  Innovation and Competitive Characteristics in Local Forest Industry Enterprises: A Case Study; [Inovacijska i konkurentska obilježja lokalnih poduzeća drvne industrije: studija slučaja]

  Komut, Osman; Karabulut, Ayşenur

  The forest products industry makes significant contributions to national economies in terms of basic economic indicators such as employment, expansion into rural areas, added value, investment and exports. This study aims to measure the innovation perception, awareness and competitiveness of small and medium-sized forest products enterprises operating in local areas on the basis of different variables. Within the scope of the study, a data collection tool including on-site observation, interviews and the developed scale was used on enterprises located in a local administrative region. The data obtained were subjected to hypothesis testing and correlation analysis. The findings revealed that the perception of innovation in small and medium-sized forest products industry enterprises is affected by demographic factors related to the enterprise managers, and basic factors related to the enterprise such as the number of employees, field of activity, duration of activity, annual average income, and product distribution channels. Furthermore, it has been determined that innovation awareness decreases as the scale of the enterprises shrinks. As a result, it can be said that the innovation and competition characteristics that are valid in the global and national forest products industry market are not yet fully applicable to local-scale and low-capacity enterprises.

  Öz, Mehmet; Okan, Onur Tolga; Baltaci, Cemalettin

  Natural plants are abundant in their native habitats and are traditionally used to treat a variety of health conditions. The Rosa genus stands out as an important species rich in bioactive compounds. This study, conducted in Türkiye, aimed to analyse the antioxidant and phenolic profiles of methanolic extracts obtained from different parts of Rosa canina (R.c.) and Rosa pimpinelifolia (R.p.) collected in 2021 and 2022. The antioxidant activity values of R.c. collected in 2021 and 2022 were found to be between 5 102.31–46 396.36 mmol Fe(II)/100 g in ferric reducing antioxidant power (FRAP), 141.92–377.54 mg ascorbic acid equivalents (AA)/kg in total antioxidant capacity (TAC), 2.18–24.68 µg/g in 2,2-diphenyl-1-picrylhydrazyl [DPPH (EC50)] and 34.31–75.77% in DPPH (% inhibition). Antioxidant activity of R.p. collected in 2021 and 2022 ranged from 17 258.44–71 903.20 mmol Fe(II)/100 g, 271.69–479.19 mg AA/kg, 1.02–8.32 µg/g and 50.98–85.57% for FRAP, TAC, DPPH (EC50) and DPPH (% inhibition), respectively. The R.p. extracts generally exhibited higher antioxidant activity than those of R.c. Considering the total identified phenolic compounds achieved from different plant parts of rosehip for both years, the highest values of total phenolic compounds were determined in R.c. leaves (222.08 mg/100 g) in 2021, and R.p. leaves (5 465.95 mg/100 g) in 2021.

  Investigation of Noise Exposure Levels in Furniture Industry: The Impact of Enterprise Scale and Machine Operational States; [Istraživanje razina izloženosti buci u industriji namještaja: utjecaj veličine poduzeća i radnih stanja strojeva]

  Öztürk, Erhan; Komut, Osman; Fidan, Muhammed Said

  The furniture industry is characterized by the intensive use of cutting, shaping, and surface-treating machinery, which naturally generates high noise levels. This study aimed to assess noise exposure levels in furniture manufacturing facilities by examining the effects of enterprise scale, machine types, and working conditions (loaded and unloaded) on occupational health and safety (OHS). The study was conducted in a total of 30 enterprises, 10 at each enterprise scale level. Physical risk factor data for noise were recorded using on-site measurements for the machines and production lines used at each enterprise level, depending on various variables. ANOVA, T-test, and Correlation analyses were performed to determine the relationships between the variables. The results revealed that small-scale businesses were the riskiest group in terms of noise levels. Generally, although measured noise levels in workplaces remain below the highest exposure action value of 85 dB, critical levels have been detected under specific machinery and working conditions. In machine-based assessments, the critical machines exceeding the highest exposure value of 85 dB are: In small-scale businesses – planing machine (95.26 dB), circular saw (88.08 dB) and band saw (86.81 dB); in micro-scale businesses – CNC drilling machine (91.13 dB), CNC sizing machine (88.01 dB) and band saw (85.95 dB); and in medium-scale businesses – circular saw (85.24 dB). As a result of the study, it has been emphasized that long-term noise exposure poses a risk to employees’ hearing health and that preventive measures are therefore mandatory.

  Chemical Profiling of Stachys cretica subsp. anatolica Rech. f. (Endemic) Essential Oils and their Methanol Extracts with Evaluation as Enzyme Inhibitors, Antioxidant, and Antimicrobial Agents

  Öz, Mehmet; Fidan, Muhammed Said; Baltacı, Cemalettin; Akmeşe, Osman; Sefalı, Abdurrahman; Aygül, İmdat

  Enzyme inhibition activities, phenolic compounds, antioxidant activities, bioactive compounds, antimicrobial activities, and chemical components of essential oil and methanol extracts obtained from the aerial parts of S. cretica subsp. anatolica were investigated. The main phenolic compounds of aerial parts were catechin, oleuropein, and epicatechin. The determined enzyme inhibitor activities highlight the potential of S. cretica subsp. anatolica as a source of bioactive compounds, particularly for carbonic anhydrase and cholinesterase inhibition. The essential oil and methanol extract exhibited remarkable activities against CA-II, AChE, and BChE, although they were less potent than standard inhibitors. The essential oils generally showed stronger antimicrobial activity compared to the 30% methanol extracts across most bacterial and fungal strains, as evidenced by minimum lethal concentration (MLC) and lower minimum inhibitory concentration (MIC) values and larger inhibition zones. Chloramphenicol used alone exhibited the highest antimicrobial efficacy, with the lowest MIC and MLC values and the largest inhibition zones. The essential oils of S. cretica subsp. anatolica were determined as esters, oxygenated sesquiterpenes, and aldehydes in aerial parts. The main components were found to be hexahydrofarnesyl acetone in the aerial parts.

  Influence of Container Type and Growing Media on Seedling Growth of Pinus sylvestris in the Nursery

  Tilki, Fahrettin; Er, Omer

  Type of container and growing media are two important factors that affect seedling quality. The present study aimed to evaluate the effects of the growing media (local peat sources and Finnish peat) and Enso tube containers (type with vertical slits and rocket type) on the morphological attributes of two-year-old container-grown Pinus sylvestris L. seedlings using a completely randomised block experimental design in the nursery. Both container types and growing media significantly affected some seedling morphological attributes such as seedling height (SH), root collar diameter (RCD), the Dickson quality index (DQI), shoot and root dry weights (SDW and RDW, respectively), and sturdiness quotient (SQ) of P. sylvestris seedlings. When the containers were evaluated, the fixed Enso container type with greater volumes, which has vertical slits on the sidewalls, gave better results in terms of most measured seedling morphological characteristics than the Enso-rocket container type with smooth walls. It was also determined that the growing media significantly affected P. sylvestris seedlings’ morphological indices, and low growing media acidity because high local peat pH decreased some morphological quality attributes of P. sylvestris seedlings. The results suggest that lowering local peat pH can increase the potential of local peat as a Finnish peat substitute in container growing media for P. sylvestris seedling production.

  Chemical Profiling and Biological Activities of Methanol Extracts and Essential Oils From Ferulago Platycarpa Boiss. & Balansa (Endemic): Enzyme Inhibition, Antioxidant, and Antimicrobial Properties

  Aygül, İmdat; Öz, Mehmet; Fidan, Muhammed Said; Baltacı, Cemalettin; Akmeşe, Osman; Sefalı, Abdurrahman

  This study aimed to evaluate the phytochemical composition and biological activities of Ferulago platycarpa methanol extract (ME) and essential oil (EO). The EO was obtained via hydrodistillation and analyzed by GC-MS, revealing sesquiterpene hydrocarbons as the dominant class, with caryophyllene (65.8%) and α-pinene (9.65%) as the major constituents. The methanol extract was subjected to LC-MS/MS analysis, which identified eleven phenolic compounds, with chlorogenic acid as the most abundant. The extract showed significantly higher total phenolic (1196.22±11.64 mg GAE/100g) and antioxidant (1870.00±17.69 mg QEE/100g) contents compared to the ME. In vitro enzyme inhibition assays demonstrated that the methanol extract exhibited potent inhibitory activity against carbonic anhydrase II (CA-II, ICSO= 0.023 pg/mL), acetylcholinesterase (AChE, ICSO= 110 pg/mL), and butyrylcholinesterase (BChE, IC50= 390 pg/mL). In contrast, the EO showed higher inhibition against α-amylase (IC50= 5920±10.45 pg/mL) and BChE (IC50= 1.32±0.65 pg/mL), while its α-glucosidase showed no inhibition. Antioxidant assays indicated superior activity for the methanol extract compared to the EO. Furthermore, antimicrobial testing revealed that the EO demonstrated broader and more effective antimicrobial action, exhibiting lower MIC and MBC values against several bacterial and fungal strains. Collectively, these results highlight F. platycarpa as a valuable source of bioactive compounds with promising applications in antidiabetic, neuroprotective, antioxidant, and antimicrobial therapies.

  Örümcek ormanlarının topraküstü karbon depolama miktarlarının bazı ekolojik faktörler açısından değerlendirilmesi (Gümüşhane-Kürtün)

  Güvendı, Engın; Kahyaoğlu, Nuray; Ertuğrul, Murat Han

  Giriş ve Hedefler Ülkemizdeki farklı orman ekosistemlerinin karbon bağlama potansiyelinin belirlenmesine ve tahmin edilmesine yönelik çalışmalar incelendiğinde sadece ağaçlar üzerinde çalışmalar yapılmış olduğu görülmektedir. Ancak “Orman” deyimini sadece ağaç topluluğu olarak algılamak doğru değildir. Ormanı ağaçlarla birlikte aralarında karşılıklı etki ve ilişkiler bulunan diğer bitkiler, hayvanlar, mikroorganizma, toprak, hava, su ve iklim gibi diğer doğa faktörlerinin birlikte oluşturdukları bir sistem olarak kabul etmek gerekir. İşte bu nedenledir ki; söz konusu çalışmada, Gümüşhane-Kürtün yöresi için çok büyük öneme sahip olan Örümcek Ormanları, klimatik, edafik (toprak özellikleri), fizyografik (denizden yükseklik, bakı, eğim) ve biyotik (arazi kullanım sınıfı, bonitet) özellikler bakımından incelenerek yükselti, eğim ve bakı etmenlerine göre karbon depolama miktarlarının belirlenmesi amaçlanmıştır. Yöntemler Araştırmanın gerçekleştirilmesine yönelik gerekli veriler amenajman planlarından elde edilmiştir. Topraküstü biyokütle ve buna bağlı olarak topraküstü karbonun hesaplanması için literatür verilerinden yararlanılmıştır. Çalışmada yapılan hesaplama ve haritalama çalışmaları Coğrafi Bilgi Sistemleri ortamında gerçekleştirilmiştir. Bulgular Toplamda 30332,48 ha alanda depolanan topraküstü karbon değerleri toplamının 485249,30 ton/ha olduğu belirlenmiştir. Çalışma sonucunda; en fazla topraküstü karbon, yükselti basamaklarına göre 288247,77 ton ile 1501-2000m aralığında, eğim sınıflarına göre 464121,69 ton ile pek sarp alanlarda, bakı gruplarına göre 340870,72 ton ile kuzeyli bakılarda, bonitet sınıflarına göre 332907,65 ton ile IV. bonitet sınıfında, arazi kullanım sınıflarına göre ise 477058,26 ton ile verimli orman alanlarında olduğu belirlenmiştir. Sonuçlar Böylesine büyük bir öneme sahip olan Örümcek Tabiatı Koruma Alanı’nda yetişme ortamı koşulları ve ormanın yapısı çok iyi etüt edilmelidir.
