MPACT OF CLIMATE CHANGE ON Ambrosia artemisiifolia L.

Climate change is one of the most pressing global challenges of the 21st century, influencing various ecological processes and species distributions. One of the many species affected by these changes is Ambrosia artemisiifolia, a plant native to North America that has established itself in various regions and successfully spread to all continents except Antarctica over the last two centuries. Known for its potent allergenic pollen, common ragweed presents a significant threat to public health, agriculture, and ecosystems. As climate change continues to alter environmental conditions, its spread and impact are likely to intensify. Climatic changes have become increasingly evident in Serbia, particularly over the last two decades. In our region, we are witnessing hotter summers and a growing imbalance in rainfall during the growing season. However, these conditions did not limit the spread of ragweed, which has become increasingly common in Serbia, particularly in ruderal habitats.
