ÖgeExamining 4600 years of human-environment interaction:climate and vegetation history around lake burdur(Southwestern Türkiye) through palynological analysis(Graduate School, 2024-06-10) Elmas, Ümit Cevher ; Biltekin, Demet ; 603211011 ; GeoanthropologyBurdur, located at the intersection of the Mediterranean, Aegean, and Central Anatolia, boasts a rich history of continuous human habitation spanning millennia. Despite extensive scholarly focus on the region's historical and archaeological development through various methods, a significant research gap persists regarding ancient climate, vegetation, and the intricate relationships between humans and the environment. To address this comprehensively, sediment core BRDR-2, retrieved from Lake Burdur and dating back approximately 4,600 years BP (around 2650 BC), underwent palynological analysis. This analysis integrates multiple approaches, including the examination of various proxy records around the study region and the incorporation of paleoclimatic data from sources like CHELSA and Paleoview, as well as historical accounts. By merging diverse scientific approaches, this research aims to illuminate the complex interactions that have shaped the historical landscape of the Burdur Basin and offer insights into its enduring significance. According to the pollen analysis, the basin is dominated by Quercus ilex-coccifera type (evergreen Quercus), Olea (olive), Juglans (walnut), and pine trees (Pinus brutia and Pinus nigra). Additionally, among coniferous trees, Cedrus libani (cedar) stands out, indicating the long-distance transportation of this species from the Taurus mountain ranges. The fossil pollen analysis shows that alongside salient climatic changes during the Early Bronze Age, settlement expansion and population growth had a noticeable impact on vegetation, resulting from a significant increase in agricultural activities. This analysis also indicates the signals of the Beyşehir Occupation Phase (BOP), marked by increased agricultural activities and a significant trend toward extensive deforestation, a pattern commonly observed in pollen sites across the Eastern Mediterranean. Notably, this phase occurred in Burdur within a distinct timeframe, beginning during Roman expansion and persisting until the Early Modern Ottoman Period, compared to other sites in the region. While other regions experienced similar anthropogenic influences, Burdur's unique timeline of these events highlights a distinct pattern. During the Roman period, significant agricultural intensification and deforestation were evident, continuing into the Early Modern Ottoman period. This contrasts with other areas where such activities might have started later or ended earlier. Considering the amplification of this anthropogenic activity alongside corroborating proxy data and paleoclimate models in the area, it can be suggested that the climatic influence on this trend might be relatively indirect, while humans may have had a more significant impact on the landscape. The distinct pattern observed in Burdur underscores the region's unique response to broader climatic and human-induced changes, offering a valuable case study for understanding human-environment interactions over millennia.

Öge3D modeling in archaeology Reşitköy Dam excavations(Graduate School, 2025-01-31) Tok, Kalin ; Özcan, Orkan ; 603211009 ; Geoanthropology3D (3 Dimensional) modeling has profoundly transformed archaeology by introducing innovative methods for documenting, analyzing, and presenting data. This technology surpasses traditional techniques that rely on sketches, photographs, and physical records by offering dynamic, precise, and interactive means of preserving archaeological sites and artifacts. The integration of 3D technologies addresses the limitations of conventional practices, enriching the scope and depth of archaeological studies and fundamentally enhancing the discipline's ability to safeguard cultural heritage. The primary advantage of 3D modeling is its ability to create detailed digital replicas of archaeological sites. These models capture intricate features with remarkable precision, ensuring that valuable information is preserved and accessible without damaging fragile originals. Furthermore, digital reconstructions enable archaeologists to visualize and analyze historical structures in their original context. This capacity for digital preservation is particularly critical in the face of environmental degradation, conflicts, or other threats to physical resources heritage such as, illegal excavations, environmental factors, or urbanization. 3D modeling provides numerous benefits that make it essential in modern archaeology. It greatly improves the capability to preserve and share archaeological data worldwide, encouraging collaboration among researchers and enhancing public engagement. Techniques like photogrammetry and laser scanning capture fine details often missed by traditional methods, allowing for more accurate measurements and analyses. In educational settings, 3D models offer immersive experiences, including virtual tours of ancient sites, which enrich learning and create a deeper connection to history. These models also play an essential role in restoration efforts, serving as templates for accurately reconstructing damaged or incomplete artifacts and structures. Moreover, employing 3D modeling can shorten the time and reduce costs related to fieldwork and analysis, boosting efficiency without sacrificing accuracy. In comparison to traditional methods, 3D modeling represents a significant advancement. Conventional documentation often lacks the spatial and textural detail provided by digital technologies and is prone to inaccuracies and deterioration over time. Physical replicas, while valuable, are expensive and frequently fail to replicate fine details necessary for comprehensive analysis. By contrast, 3D models ensure exhaustive documentation, integrating spatial, material, and geospatial data into cohesive digital formats that are easily analyzed, stored, and shared. Overall, 3D modeling represents a technological advancement in archaeology, addressing the limitations of traditional documentation while enhancing preservation, research, and public access. Its integration into archaeological practice ensures that cultural heritage is meticulously documented and widely accessible, providing an invaluable resource for future generations and the global community.

ÖgeA multidisciplinary approach to sustainable agriculture: the impact of microbial and organomineral fertilization on soil bacteria, crop yield, and farmer adoption(Graduate School, 2025-05-25) Doruk Alat, Ceyda ; Arıkan, Bülent ; 603211001 ; GeoanthropologySoil health and microbial diversity are critical components of sustainable agriculture, directly influencing crop productivity and environmental stability. However, conventional agricultural practices, particularly the excessive use of chemical fertilizers, have led to soil degradation, microbial imbalance, and long-term ecological concerns. These issues have highlighted the urgent need for alternative approaches to fertilization that promote soil sustainability without compromising crop yield. In recent years, microbial inoculants and organomineral fertilizers have gained attention as potential ways to improve soil health and support plant growth. They also offer a safer alternative to chemical inputs by reducing their environmental impact. This study investigates how evidence from microbial, organomineral, and combined application of fertilizers affects soil microbial diversity, soil quality, and crop yield in agricultural fields in Çumra, Konya. To achieve this, 16S rRNA gene sequencing was used to analyze the dynamics of microbial compartments under different fertilization methods, both before and after planting. Sequencing results revealed clear shifts in microbial composition, particularly highlighting the dominance of Vibrio species after harvest and in continuously cultivated areas, likely linked to irrigation. Some bacterial genera known for their stress tolerance, like Rubrobacter and Microvirga were dominant in previously uncultivated soils before planting. In addition to microbial profiling, soil physicochemical analyses revealed that organic matter and potassium levels were positively correlated with bacterial diversity, especially in the combined treatment group, where organic matter content reached the highest levels. The research results show that the combined use of microbial and organomineral fertilizers stabilizes soil bacterial diversity, improves nutrient availability, and promotes better plant growth compared to using microbial or organomineral fertilizers alone. The interaction between microbial inoculants and organomineral fertilizers maintains a more balanced soil bacterial community compared to application of these fertilizers alone. These findings suggest that adopting a combined fertilization approach may be important to increase agricultural productivity while reducing dependence on synthetic fertilizers, which are associated with negative environmental impacts such as groundwater pollution and greenhouse gas emissions. Farmers face challenges in implementing sustainable fertilization techniques due to economic constraints, lack of knowledge, and limited access to biofertilizers. Although this research highlights the advantages of microbial and organomineral fertilizers, widespread adoption requires policy support, financial incentives, and technical support to encourage farmers to transition to more sustainable agricultural practices. Addressing these barriers through educational/training programs and government subsidies can accelerate the adoption of biofertilization methods and thereby increase agricultural productivity in an environmentally sustainable manner.
