Summary: Fertility variation and gene diversity in seed stands can be estimated by measuring the difference in strobilus production between female and male parents. Pooling strobilus production across different years and populations can increase the effective number of parents (N(p)), therefore increasing gene diversity. However, striking a balance between the size of N(p) and the number of years for pooling is crucial for maintaining gene diversity in natural stands.

Summary: This study aimed to determine the impact of crown closure classes and growth characteristics on cone production, fertility variation, and gene diversity in natural populations of Taurus cedar. The results showed that crown closure significantly affected cone production, fertility variation, and gene diversity. The highest cone production was observed in trees with full crown closure, while gene diversity decreased from degraded forest to full crown closure. Additionally, there were significant correlations between cone production and crown closure, as well as between diameter at breast height and cone production.

Summary: The study examined the Taurus cedar populations in southern Turkey, analyzing the relationships between reproductive traits and growth traits, and estimating genetic parameters. Despite similar growth characteristics among populations, significant differences were found in terms of reproductive traits.

Summary: Recent research has shown that assessing the wood, dormant, and phloem characteristics of Cedrus libani trees can help understand their growth conditions and vitality. The number of dormant cambial cells, widths of xylem and conducting phloem were found to be important indicators of tree vitality, while altitude did not have a direct impact on these parameters.

Summary: This study aims to investigate the metabolite profile and the mechanism of anticancer effect of Cedrus libani tar on colon cancer cells. The results show that Cedrus libani tar has a high cytotoxic effect on colon cancer cells and increases ROS production. Metabolite analysis reveals the presence of abundant fatty acids, phenolic compounds, and organic acids in Cedrus libani tar.

Summary: Ongoing climate change is affecting the growth conditions of native conifers in Central Europe, leading to the exploration of alternative conifer species that are more tolerant to novel climatic conditions. Cedrus libani (Lebanon cedar) showed the highest resistance, recovery, and resilience to climatic extremes compared to native Picea abies (Norway spruce) and Pinus sylvestris (Scots pine). The study analyzed growth responses of these tree species to climate parameters over a period of 25 years to identify their tolerance towards climate stress events.

Summary: This study investigated the impact of different Effective Microorganism (EM) varieties on the physiological characteristics of Taurus cedar seedlings, finding that EM-5 had positive effects on most physiological parameters. Applying EM at the beginning of the vegetation period was found to enhance the physiological quality of seedlings.

Summary: Research has found that the distribution range of the cedar of Lebanon has changed over time, expanding to Western and Southern Anatolia during the mid-Holocene period, and later shrinking to the Western Anatolia region. The possibility of reforestation leading to the existence of remnant forests in Northern Turkey and the substantiation of the Hittite myth are supported.

Summary: The study successfully extracted sporopollenin and loaded oxaliplatin into it for controlled drug release, demonstrating a slow release effect. Real-time cell analysis and gene expression detection confirmed that sporopollenin-mediated oxaliplatin controlled release promotes apoptosis without causing negative effects on nearby healthy cells.

Summary: This study assessed the habitat suitability for natural regeneration of Cedrus libani in the Cedar and Fire Reserve in Slenfeh region of Syria using satellite imagery and Digital Elevation Model. The results showed that a certain percentage of the area is suitable for the natural regeneration of Cedrus libani. The model predicted natural regeneration with a high accuracy of 75% in Slenfeh region.

Summary: The study investigated the population density of the aphid, Cinara cedri, on Cedar seedlings grown in four different soil treatments. It was found that cedar seedlings grown in worm-added soils had considerably less aphid colonization. Additionally, the cedar shoots grown in soils with both worms and fertilizers showed a marked increase in growth compared to other soils.

Summary: Irrigable farmland is limited in the Central Taurus Mountain region of Turkey, leading to most rain-fed land being used for wheat and chickpea cultivation. Introducing high-yield almond varieties from the US, Spain, and France offers new opportunities for local farmers. However, due to the fragmented terrain, establishing an almond orchard is expensive for low-income villagers.
