MAPPING THE SALINITY STATUS OF AGRICULTURAL SOILS BETWEEN KIRIKHAN-KUMLU IN THE EASTERN MEDITERRANEAN REGION OF TURKEY WITH GEOGRAPHIC INFORMATION SYSTEMS (GIS)

In this study, it was aimed to determine the salinity status of agricultural soils between Kırıkhan-Kumlu in the Eastern Mediterranean region of Turkey by mapping with Geographic Information Systems (GIS). For this purpose, a total of 60 soil samples were taken from 0–20 and 20–40 cm depths and from 30 different points to represent the agricultural soils of Kırıkhan-Kumlu region in the Eastern Mediterranean region of Turkey. In the soil samples, pH, cation exchange capacity (CEC) and exchangeable cation (ECC) values were determined to determine some soil properties. Total salt, salinity class, sodium adsorption rate (SAR), exchangeable sodium percentage (ESP) and soluble cations (Na, Ca and Mg) were determined to determine the salinity status of the soils. According to the results of the research; as a result of the analysis carried out to determine the salinity status of the soils; pH values were determined between 6.91–7.98; total salt content between 0.02–0.13%; SAR values between 0.023–0.044 me/100 gr; ESP values between 0.35–2.96%; soluble Na content between 0.019–0.034 me/100 gr; soluble Ca content between 0.018–0.245 me/100 gr and soluble Mg content between 0.037–0.113 me/100 gr. In addition, by applying the ESP-SAR regression relationship of the soils, it was revealed that the soils tended to alkalize towards the lower layers. The salinity values obtained as a result of the study were transferred to the Geographic Information Systems (GIS) environment and interpolated by Kriging method and a salinity map of the study area was created. In conclusion, as a result of the research conducted in the soils of the study area in the Eastern Mediterranean region, it was determined that all of the agricultural soils of Kırıkhan-Kumlu region were classified as non-saline and that the soils did not have any problems in terms of salinity.

Factors affecting fruit damage caused by Thrips hawaiiensis (Morgan) (Thysanoptera: Thripidae) in citrus lemon groves in Turkey

The Hawaiian flower thrips, Thrips hawaiiensis (Morgan) (Thysanoptera: Thripidae) is an economically important invasive species in citrus grown in the eastern Mediterranean region of Turkey. The diverse impacts of temperature on arthropods are well documented. This study was conducted with the aim of determining the influence of day-degree on insect population dynamics and crop damage levels in Mersin Province, Turkey during 2018–2019. In 2018, the first damage caused by T. hawaiiensis was observed at 300 degree-days (DD), while in 2019, it occurred at 800 DD. The damage percentage was recorded as 28% in the lemon grove, where the population of second instar larvae briefly reached a high level (approximately 2 individuals per fruit). During 2019, the average temperature remained relatively low, and the initial population density of thrips was below the 33-day development threshold (10.4 °C) from January to April. This pattern was observed even during the mild spring season. Additionally, in both sampling locations, the high adult densities, mainly adult females, led to the shedding of a limited number of flowers that had formed in June.

REE and trace element mobility during the transformation of basalt to laterite and bauxite, Payas Province, Türkiye

The bauxites of the Payas area in the eastern Mediterranean region of Turkey occur as a stratigraphically continuous layer between Early and Late Cretaceous shallow marine carbonates. The laterites represent an in situ formation and mark a key stratigraphic layer in the region. Bauxite pockets are also present in the laterites, formed from the reworking of the laterites and accumulated in depressions in the karst terrain. Therefore, bauxite occurrences are found locally in this stratigraphic layer. The parental rock was a Ti-rich basalt that is compositionally similar to Hawaiian basalts, as indicated by petrographic features and distinctive trace element composition (Zr/TiO2 and Nb/Y). The behavior of elements during the lateritization and bauxitization processes was interpreted using the composition of the Hawaiian basalts with the iron laterite and Ti-rich bauxites of the Payas Region. During lateritization, Fe, Al, Ti, Cr, Nb, and Ta, were largely immobilie while REE and other trace elements, except for Rb, Ni, Co, and Pb were significantly removed. Approximately 75 % of the REE were removed at the end of the bauxitization and/or transportation of the lateritic soil into the karstic depressions. REE were not equally mobile with La to Ce and Lu to Yb having a relatively lower mobility than highly mobile middle REE. During the transformation of laterite to bauxite, low mobility elements such as Ti, Nb, Th, Cr, Hf, and Sn were enriched in the bauxite phase. In comparison to other elements, Rb, As, Pb, Mo, and Ni were strongly removed from the lateritic material during the bauxitization processes. The transfer of MREE during lateritization and bauxitization would have resulted in the enrichment of both light and heavy REE (concave pattern) in contemporaneous seawater. In other words, silicate weathering periods on land should be marked by a concave REE pattern with positive Eu anomaly in marine sediments throughout the geological period.

(), H. kankilicorum sp. nov. () and H. yanardagi sp. nov. () are described from the eastern Mediterranean region of Turkey. Among three new species of Dasumia, D. antalyaensis sp. nov. and D. capacii sp. nov. are related to other congeners known from Turkey, while D. yagmuri sp. nov. is quite different from other known Dasumia species. Among five new species of Harpactea, three species; H. bilecenoglui sp. nov., H. elvericii sp. nov. and H. yanardagi sp. nov., due to their spiniform emboli, are close to H. sanctaeinsulae and H. isaurica, previously described from Turkey. Two other new speciess, H. bilgenur sp. nov. and H. kankilicorum sp. nov., exhibit the characteristics of the rubicunda species group like almost all of the Turkish Harpactea. However, these two new species have a more complex palp structure.

Design and performance analysis of a green house based on hybrid and passive energy systems: A case study

ABSTRACT The energy standard in buildings depends on reducing energy consumption and saving energy. Therefore, enhancing the energy efficiency of buildings may be achieved by low-energy passive or hybrid systems. In this study, a passive and hybrid system is designed, and electrical energy generation is provided by a photovoltaic (PV) solar panel and wind turbine (WT). Moreover, the Trombe Wall (TW) is used as a passive system for heating the building, and solar collectors are used to provide hot water for the building. According to the results of the analysis, the total annual energy production from PV solar panels and WT is 15.968 kWh and 2832.4 kWh, respectively. Furthermore, it is estimated that the PV solar panel system will provide an average annual financial saving of 81.62%, and the investment cost of the WT will pay for itself in approximately 4 years. The results showed that the amount of electrical energy obtained from WT and PV solar panels is significantly increased by using clean and renewable energy sources in the designed system. Considering these results, the total annual energy production for the system is a good indication that grid-connected system installations in Osmaniye, which is located in the eastern Mediterranean region of Turkey, are applicable energy solutions for other areas and government buildings.

INVESTIGATION OF WETLAND AWARENESS OF GIFTED STUDENTS

Wetlands such as lakes, reeds, marshes and deltas are in danger of extinction in the world and in Turkey. The aim of this study is to examine the wetland awareness of gifted students. Wetland awareness of gifted students was examined according to gender and grade level variables. The research was carried out with 120 secondary school students studying in a science and art center in the eastern Mediterranean region of Turkey in the 2022-2023 academic year. In the study, the survey model, which is one of the quantitative research methods, was used. “Children's Wetland Awareness Scale” was used to collect data. The scale includes two sub-dimensions: awareness of the importance of wetlands and the problems experienced, and awareness of wetlands in terms of bird species diversity. As a result of the research, it was concluded that the wetland awareness of the gifted students was at a high level. It was determined that there was no statistically significant difference according to gender and class level in the wetland awareness scale from the eyes of the children, the importance of wetlands and the awareness of the problems experienced, and the wetland awareness dimensions in terms of bird species.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0001/a.php" alt="Hit counter" /></p>

Comparing actual evapotranspiration estimations by METRIC to in-situ water balance measurements over an irrigated field in Turkey

ABSTRACT Estimating actual evapotranspiration (ETa) rates in large-scale irrigation schemes is of great importance to improve water use efficiency. Crop types can be determined by employing remote sensing techniques coupled with ground truth data. This study aimed to: (a) conduct a water balance study by making in-situ water balance measurements, (b) derive cropping pattern maps, (c) acquire crop evapotranspiration (ETc), (d) generate fully distributed ETa maps, and (e) compare ETa estimations with ETc and in-situ water balance. Landsat 7 and 8 satellite data, and meteorological data were used to estimate ETa in the Eastern Mediterranean Region of Turkey in the 2021 hydrological year. Crop types were classified using Sentinel 2A–2B satellite images. The change in catchment storage was +67.08 mm with a 3.34% water balance closure error. The correlation between ETa and ETc for irrigated wheat, potato, lettuce, corn-1, peanut-1, soybean-2, and citrus was significant in the growing season.

Human papillomavirus vaccine administration among women in the Eastern Mediterranean region of Turkey: prevalence and barriers.

Human papillomavirus (HPV) vaccines are very effective in preventing HPV infection and related diseases. This study aimed to determine the prevalence of the HPV vaccine administration and barriers to vaccination among women aged 15-49 years. This cross-sectional study was conducted on 401 women aged 15-49 years. The prevalence of women who received the HPV vaccine, their knowledge about HPV in general, HPV screening tests, HPV vaccine and the current HPV vaccination program were evaluated. Barriers to getting the HPV vaccine were questioned. The mean age of women who had received the HPV vaccine was 30.87±8.89 and the mean age at the first sexual intercourse was 22 years. 3.2% of women received HPV vaccine. The most important factor impeding the vaccination was unawareness of the HPV vaccine and the high cost of the vaccine. If the vaccine was free, most (81.2%) of the participants stated that they would vaccinate themselves and their children (72.8%). The highest lack of information was observed about the vaccination program and vaccinated women were more informed about HPV, HPV screening tests, HPV vaccine and the vaccination program. The increase in the knowledge about the HPV vaccination program increased the probability of getting vaccinated by an odds ratio (OR) of 4.43 times. The most important barriers to HPV vaccination were the lack of public funding for vaccines and the lack of information. We recommend increasing educational activities on the HPV vaccination program and public funding of vaccination.

First Record of the Predatory Insects, Androthrips ramachandrai (Karny) (Thysanoptera: Phlaeothripidae) and Montandoniola indica Yamada (Hemiptera: Anthocoridae) on the Pest Thrips, Gynaikothrips ficorum (Marchal) (Thysanoptera: Phlaeothripidae) in Turkey

The Cuban laurel thrips, Gynaikothrips ficorum (Marchal) (Thysanoptera: Phlaeothripidae), is widely distributed to the eastern Mediterranean region of Turkey and causing damage to Ficus microcarpa var. nitida plants. Biological control of G. ficorum has a crucial role to maintain the population density of this pest insect at an acceptable level on Ficus trees. For this reason, to determine the potential biological control agents of this pest, survey studies have been done in Adana and Mersin provinces. The Androthrips ramachandarai (Karny) (Thysanoptera: Phlaeothripidae), and the Montandoniola indica Yamada (Hemiptera: Anthocoridae) were reported for the first time in Turkey in 2020 on G. ficorum that damaging young leaves of the F. microcarpa. Brief diagnoses of G. ficorum and both predatory species were provided. A total of 249 adults of A. ramachandrai and 461 individuals of M. indica were detected in the galled leaves infested with G. ficorum. Moreover, 1959 adults, 1335 immatures and 11851 eggs of G. ficorum were also recorded. There was a positive relationship between pest eggs-A. ramachandrai adults and pest larvae-M. indica adults. Ratios of prey/predatory insects indicated that the predators might have the capability in suppressing the pest thrips on Ficus trees.

Cropping pattern classification using artificial neural networks and evapotranspiration estimation in the Eastern Mediterranean region of Turkey

Determination of cropping pattern is a very important factor in quantifying irrigation water requirements at a catchment scale. In this regard, remote sensing is a robust tool for generating spatial-temporal variation of crops. This study focuses on crop classification by using remotely sensed data coupled with ground truth data. Therefore, this study aimed at both classifying each crop type and calculating crop evapotranspiration (ETc) based on reference evapotranspiration (ETo) by using the Penman-Monteith evapotranspiration model and crop coefficient (Kc). ETo was estimated by using data from two meteorological stations located in the study area. To this end, this study was conducted in Akarsu Irrigation District (≈95 km2), a sub-catchment in the Lower Seyhan Plain (LSP), in the 2021 hydrological year. Ground truth data were collected in the two growing seasons. The ENVI program was used to classify crop types from Sentinel 2A-2B satellite images with 10-m by 10-m spatial resolution. Image analysis results demonstrated that bare soil and citrus made up more than half of the area in the winter season, while corn and citrus were preponderant in summer. In addition, the total reference evapotranspiration and crop evapotranspiration were about 1308 mm and 890 mm, respectively in the 2021 water year. ETc values for second crop soybean, first crop corn, wheat, and citrus showed agreement with previous studies of direct methods of evapotranspiration in the Cukurova region. Furthermore, research findings led us to conclude that using remotely sensed satellite data in cropping pattern determination is promising in identifying the crops grown in large agricultural lands. Moreover, remote sensing images can be used to classify accurately crops in the winter and summer seasons, and this study has expanded the application value of remotely sensed data in large-scale irrigation schemes.

Wildfire susceptibility mapping can be affected by several factors. One of the most influential factors is inventory data, its extent, format, and reliability. This study aims to evaluate if the Support Vector Machine (SVM) has the capability to detect and map the forest fire susceptible areas under limited training data conditions. To test this hypothesis wildfires in Mugla province located in the Eastern Mediterranean Region of Turkey have been selected as a pilot study area. The wildfire started in Mugla, on 29 July 2021, that considerably affected the residential areas, animals, and vast areas of forests. Fourteen wildfire influential variables have been used in the analysis as independent variables. Accuracy assessment has been implemented using the Area Under the Curve (AUC) technique. Success rate and prediction rates were (91.42%) and (87.69%) respectively. According to the prediction rate, SVM successfully recognized other burnt areas as the most susceptible regions.

Detection and the Prevalence of Prune Dwarf Virus (PDV) in Important Cherry Plantations of the Eastern Mediterranean Region by DAS-ELISA and RT-PCR Analyzes

In this study, the prevalence of PDV, which infects cherry (Prunus avium L.) trees and is among the important viral pathogens in Adana, Kahramanmaraş and Osmaniye provinces where cherry is extensively produced in the Eastern Mediterranean region of Turkey, was investigated. A total of 173 cherry leaf samples with and without symptoms collected from Adana, Kahramanmaraş and Osmaniye provinces were tested by DAS-ELISA and RT-PCR methods. PDV was not detected in all samples tested by the DAS-ELISA method. As a result of the tests performed with RT-PCR, 874 bp long nucleotide sequences belonging to the coat protein gene region of the 15 samples were obtained and found positive. After the sequences were obtained, they were compared with the sequences from Turkey and the sequences of PDV reference isolates registered in GenBank. As a result of BLASTn analysis, it was determined that the Turkish PDV cherry isolates showed similarity between 89.58-99.32% at the nucleotide level with the PDV reference sequence. Phylogenetic analysis of the nucleotide sequences of the obtained isolates was performed and their relationship with PDV cherry isolates in the world and Turkey was determined.

Deciphering the quality and yield of heteromorphic seeds of marigold (Calendula officinalis L.) under high temperatures in the Eastern Mediterranean region

Seed heteromorphism, which has different dormancy and germination behavior, is vital under hostile environments such as high temperatures and drought. Seed morphs of marigold were investigated in order to examine the seed heteromorphism, which correlates with environmental variability. A field experiment was conducted on 3 different planting dates (March 1st, March 15th, and April 1st, 2020) in the hot ecological conditions of the eastern Mediterranean region of Turkey. The results of this study revealed significant variations in the agronomic traits and fatty acid composition of heteromorphic marigold seeds. When the general averages were considered, the highest values for all of the studied traits were obtained from the March 1st planting date, except for the seed oil content. The seed yields and the number of seeds decreased significantly on late plantings that were more exposed to high-temperature stress. Six distinct morphs were found in the marigold seeds, comprising balloon-like, balloon-like with spines, insect-leg, winged, curved, and ring-like. The findings clearly indicated that the seed oil yield was highest in the balloon-like with spines and ring-like seed shapes. The major oil components of the heteromorphic marigold seeds were linoleic acid (37.55%–41.47%), oleic acid (21.04%–27.37%), and α-calendic acid (15.54%–22.09%). The most common seed, ring-like shaped, may play a key role in the intensive agriculture of the plant in terms of some features such as dormancy, dispersal, and cultivation techniques. As a consequence, even if multiple gradual harvests can be made in this region where global warming and climate change is felt more clearly, the marigold plants exhibited fewer capitula for the late planting dates and the ratio of seed heteromorphism changed.

Life goals and proactive career behaviors: The mediating role of visions about the future and the moderating role of intolerance of uncertainty.

Dominated by uncertainties, today’s work world pushed university students to exhibit proactive career behaviors. Thus, this created a need for more research conducted to determine the variables associated with proactive career behaviors, on the grounds that additional research may contribute to an increase in proactive career behaviors. In this context the study explored the mediating role of visions about the future and the moderating role of intolerance of uncertainty in the relationship between university students’ life goals and their proactive career behaviors. The study was carried out with 519 students (299 females and 220 males) studying at a university in the Eastern Mediterranean Region of Turkey. The Scale of Setting Life Goals with Respect to Positive Psychotherapy, the Visions about the Future Scale, the Career Engagement Scale, and the Intolerance of Uncertainty Scale were employed as data collection tools. Data were analyzed using correlation analysis, structural equation modeling methods, and regression analysis based on the bootstrap method. The correlation analysis revealed a positive relationship between proactive career behaviors, life goals and visions about the future, and a negative relationship between proactive career behaviors and intolerance of uncertainty. Furthermore, the analyses put forth that visions about the future have a mediating role in the relationship between life goals and proactive career behaviors and that intolerance of uncertainty has a moderating role in the same relationship. Increasing university students’ life goals and their visions about the future and reducing their intolerance of uncertainty will help them exhibit proactive career behaviors.
