Aim of study: Topography and climatic conditions have effected in determining the processes of the streams of the micro-watershed. Nowadays, the management plans were made for water and soil protection measures in the basins.
Area of study: This study was carried outto characterize and prioritize the streams of the Gumushane upper Harşit micro-watershed using a GIS-based spatial approach.
Material and methods: Fundamental watershed characteristics including drainage density, slope, land use types, and stream class were evaluated and interpreted for the Gumushane micro-watershed. Calculatea comprehensive value for each parameter, drainage density (Dd), flow frequency (Fs), slope (S), length of land flow (Lg), and land use (Lu) was used.
Main results: The drainage density, stream flow frequency, and form factor of the microwatershed are from -4 to 26. Finally, the weighted rankings were summarized, and all micro-watersheds were categorized to five classes based on the risk index as very low risk, low risk, medium risk, high risk, and very high risk. This risk map overlaid to land use type maps in GIS where risk areas were evaluated in the finalrisk results. The 739 ha productive forest area within very high-risk areas was changed to non-risk parameters.

Aim of study: Climate change triggers many problems, such as loss of biodiversity on land and sea, destruction of forest areas, poverty, inequality, and economic development. One of the most vital indicators of quality of life and sustainable development is temperature, humidity, and wind conditions, which are in the range of bio-climatic comfort values. The changes in these parameters due to global warming threaten vitality and affect the use of space and quality of life in cities. The study aimed to model the evolution of bioclimatic comfort zones with the effect of climate change in the research area. Area of study: The research was carried out in the Burdur Basin of Türkiye, which is an area that includes the underground and surface water bodies and the lakes region within its borders. Material and Methods: Models were produced at 20-year intervals until 2100. The spatio-temporal variations are generated according to the IPCC's SSPs 245 and SSPs 585 scenarios. The discomfort index (DI) and Effective warming wind speed (ETv) were used to determine bioclimatic comfort. Main Results: According to the DI, 87.4% of the area will be in the cold zone today, while in 2100, 50.5%, according to the SSP245, and 98.3%, according to the SSP 585 will be in the comfort zone. According to ETv, 92.7% of the area is quite cool today; by 2100, 90% of the site will be classified as slightly cool according to SSP 245, and 89.3%, according to SSP 585 will turn into mild areas. Research highlights: The results of the research reflect the spatial impact of climate change and are significant in terms of holistic risk management at the basin scale

Aim of study: The friendship between humankind and nature ended with the mechanization process initiated by the Industrial Revolution. Today, we are faced with the problems of global warming and climate change due to human factors such as fossil fuel consumption and the destruction of vegetation. These two problems promise us a warmer world, melting glaciers, burning forests, and thousands of dead people in the future. Research indicates that people’s awareness is the most important factor in combating the disastrous consequences of global warming and climate change. Based on this fact, this study aims to examine individuals’ perceptions of global warming and climate change in terms of various variables. Material and methods: The research was conducted with 2022 participants in line with the screening model. A perception scale on global warming and climate change was used as a data collection tool. The obtained data were analyzed with descriptive statistics, Mann Whitney U, and Kruskal Wallis Tests. Main results: As a result of the research, it has been determined that female participants have a positive attitude towards global warming and climate change compared to male participants, and as the age level of individuals increases, their perceptions of global warming and climate change increase. Research highlights: Awareness of people is the most important factor in the fight against the consequences of global warming and climate change. As a result of the data collected from 2022 participants, it was determined that female participants' perceptions of global warming and climate change were more positive than male participants

Aim of study: This study investigates the estimation success of using day and night segments in producing Forest Canopy Cover (FCC) maps with the Canopy Cover Estimation Model (CCEM) for the years 2020 and 2022. Area of study: The study area covers 17 interconnected counties situated in the southeastern part of Texas state, adjacent to the state of Louisiana, and near the southern coastlines, known for their extensive forested areas. Material and methods: This study incorporated both day and night acquisition segments from Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) data for a comprehensive comparison of their effectiveness in mapping the forest canopy cover using the CCEM. Main results: The study’s findings reveal that night segment-derived FCC maps outperform those derived from day segments, showing higher kappa coefficients of 0.77 and 0.83 for the years 2020 and 2022, respectively. In addition, notable differences were observed among classes of FCC estimations successes for day and night segment-derived maps. Research highlights: This study introduces a significant finding that the FCC maps derived from night segments yield more accurate results than those derived from day segments. The study further discovers a notable difference in the forest canopy cover classification success, particularly with a lower accuracy observed in the Moderate Forest Canopy Cover (MFCC) category.

Aim of study: Fire impacts biodiversity and ecosystems, and is crucial for understanding fire causes. This paper aimed to assess burned areas and severity levels in Sikkim's forest fire incidence data from 2004-2019. Area of the study: The study area for the work is the state of Sikkim, situated in the Himalayan Mountain's North-eastern region. Material and methods: Landsat 8 and Landsat 5 satellite image were used for the study and Standard vegetation indices like Delta Normalized Burn Ratio (dNBR) and Relativized Burn Ratio (RBR) are computed. Also, a linear regression analysis was performed between weather parameters like temperature (℃), wind (Km/h), rainfall (mm) on burn severity (dNBR classes) of forest fires in Sikkim between the year 2009-2019. Main results: According to the findings, out of 557 numbers forest fire incidents in Sikkim between 2004 and 2019, 250 numbers were classified as Unburned (46.21 %), 199 numbers as Enhanced Regrowth, Low (35.72 %), and 43 numbers as Enhanced Regrowth, High (7.94 %), while 32 numbers were classified as Low Severity (5.92 %), 9 numbers as Moderate-Low Severity (1.66 %), 5 numbers as Moderate-High Severity (0.92 %), and 2 numbers as High Severity (0.36 %). It was found that the wind (r=0.80, Slope=0.57, SD=0.70) and rainfall (r=0.77, Slope=-0.18, SD=7.00) showed a strong positive and strong negative linear relationships respectively in influencing the burn severity (dNBR). While, temperature (r=0.69, Slope=0.74, SD=0.01) plays a moderate positive role in influencing the burn severity (dNBR). Highlights: The study has shown the effectiveness of burn area mapping and remote sensing data products in analyzing forest fire regions with limited resources and diverse landforms and vegetation. Researchers will be able to identify the regions affected by forest fires and those that have not recovered since the fire. Goal of this research is to improve forest fire planning and management by fostering aid to the responsible authorities to evaluate the pattern of vegetation degradation in burn regions and estimate the impact of forest fires

Aim of study: In this research, the surface of Fagus orientalis (beechwood) was chosen as a substrate due to its widely used strong biostructure in the wood industry. It was functionalized with ZnO, TiO2, and FAS-17 nanoparticles to enhance its service life. Material and methods: FAS-17 (Trimethoxysilane) and ammonium hexafluorotitanate were purchased from Sigma-Aldrich, and zinc borate from Etimine S.A. Methanol, ethyl alcohol, hydrochloric acid, sodium hydroxide, and zinc oxide were provided by TEKKIM. Characterization methods included FTIR, TG/DTA, XRD, SEM, and EDX. Hydrophobicity was determined by water contact angle using KSV Cam101. UV-Vis analysis used a Shimadzu UV-160 spectrophotometer, surface roughness was measured with a Marsurf M 300 device (ISO 4287), and color analysis was performed with a Datacolor Elrepho 450 X spectrometer (ASTM 2021). Main results: The thermal stability of wood was significantly improved through the hydrothermal deposition of ZnO/TiO2 nanoparticles. Additionally, hydrophobization was achieved using Triethoxy-1H,1H,1H,2H,2H,2H-perfluorodecylsilane (C14H19F13O3Si), referred to as FAS-17. Research highlights: The study demonstrated that the introduction of ZnO/TiO2 nanoparticles improved the thermal stability of wood. Furthermore, the use of FAS-17 resulted in effective hydrophobization. The thermal stability of wood was improved with ZnO/TiO2 nanoparticles. In addition, hydrophobization was supplied by FAS-17.

UV-Vis analysis used a Shimadzu UV-160 spectrophotometer, surface roughness was measured with a Marsurf M 300 device (ISO 4287), and color analysis was performed with a Datacolor Elrepho 450 X spectrometer (ASTM 2021). Main results: The thermal stability of wood was significantly improved through the hydrothermal deposition of ZnO/TiO2 nanoparticles. Additionally, hydrophobization was achieved using Triethoxy-1H,1H,1H,2H,2H,2H-perfluorodecylsilane (C14H19F13O3Si), referred to as FAS-17. Research highlights: The study demonstrated that the introduction of ZnO/TiO2 nanoparticles improved the thermal stability of wood. Furthermore, the use of FAS-17 resulted in effective hydrophobization. The thermal stability of wood was improved with ZnO/TiO2 nanoparticles. In addition, hydrophobization was supplied by FAS-17.","PeriodicalId":17816,"journal":{"name":"Kastamonu University Journal of Forestry Faculty","volume":"36 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139349468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim of study: In this study, the effects of plant growth regulators (PGRs) on shoot multiplication of Crepis bithynica Boiss. (Asteraceae), an endangered rare species in Türkiye were investigated. Area of study: The plant samples were collected from Kastamonu Ilgaz Mountain National Park. Material and method: The nodal segments were used as explant and they were cultured on Murashige and Skoog (MS) basal media supplemented with different plant growth regulators. Morphological changes of propagated plants were monitored during 21 days in vitro cultures. Main results: All plant growth regulators induced shoot growth and development without callus formation. Additionally, the highest shoot number and length of shoot per explant were achieved in MS media supplemented with 4.4 µM 6-BA plus 0.5 µM NAA, and 4.9 µM 2iP plus 0.5 µM IBA, respectively. Highlights: This study is the first study on the effects of PGRs in shoot multiplication of C. bithynica, and the results obtained can be used micropropagation for the species.

Aim of study: This study determined whether locals’ perception of bushfire impact on rubber trees matched or mismatched with empirical data. Area of study: This investigation was conducted in Rubber Research Institute of Nigeria (RRIN) and six neighboring communities (Uhie, Iyanomo, Obaretin, Obayantor I, Ogbekpen and Obagie) in Edo State, Nigeria. Material and methods: Quantitative data on tree height, canopy, diameter at breast height (DBH) and bark were obtained by direct measurements and field observation in burnt and unburnt rubber plantations. Locals’ perceptive data were obtained through the administration of questionnaire. Descriptive statistics were used to examine data on perception of locals’ while Student-t test was adopted to determine significant differences of tree parameters in burnt and unburnt rubber plantations. Main results: There were significant differences in height, canopy and DBH of rubber trees. Besides incidences of fissured tree bark; reduction in height, canopy and DBH of trees were detected in burnt rubber plantation. Majority of the local’s agreed that bushfire negatively impacted rubber tree parameters and natives’ perception aligned with the experiential results. Highlights: Locals’ perception of bushfire effect on rubber trees accessed through the Likert-type format of questionnaire matched with empirical data.
