Discussion
In our study, ensemble models were developed for A. annua . With good accuracy, potential distributions were simulated and suitable habitats were estimated under present and future climate scenarios. The simulations indicated that the mean temperature of driest quarter was the dominant bioclimatic variable. It also showed that a huge change both on its range and location which would be caused by climate change. This result clearly pointed out that this herb would be dramatically influenced by climate change. Its future conservation and utilization must consider the impact of climate change.
