| Background: Dicrocoeliasis, caused by Dicrocoelium dendriticum, is a significant parasitic disease with a complex life cycle that affects livestock worldwide, particularly in temperate and Mediterranean regions. Objectives: This study investigates the relationship between topographic and bioclimatic variables and the parasite's distribution to identify key factors influencing disease occurrence. Methods: During the fall of 2022, 1,030 fecal samples were collected from four climatic zones in Iran: cold and semi-arid, cool and sub-humid, warm and hyper-arid, and mild and humid. The samples were analyzed using the McMaster flotation technique, and the results were further examined with ArcGIS and MaxEnt modeling to assess spatial and environmental patterns. Results: The highest infection rate (52.31%) was observed in the cold and semi-arid climate. while the lowest (30.09%) was recorded in the warm and hyper-arid climate. Jackknife analysis identified the Normalized Difference Vegetation Index (NDVI) as the most significant topographic factor influencing parasite distribution in three of the four climatic zones. The mean temperature of the coldest quarter (Bio 11) was the most influential bioclimatic variable. Slope emerged as the most critical topographic factor in the mild and humid climate. At the same time, the precipitation of the driest quarter (Bio 17) and the precipitation of the driest month (Bio 14) were the most impactful bioclimatic variables. These patterns show how topographic and bioclimatic factors affect the distribution of D. dendriticum in various climate zones. Conclusion: The study also provides helpful information for creating better control strategies and improving livestock management in affected areas, leading to more effective control of this parasite. | ||
