Investigating the distributional response of the rare and endangered plant Fritillaria przewalskii to climate change based on optimized MaxEnt model.

ABSTRACT: Climate change will lead to changes in the suitable ranges of certain species and accelerate the decline of global biodiversity, with alpine plants are particularly sensitive to these changes. Fritillaria przewalskii, a primary source for the traditional Chinese medicine Fritillariae Cirrhosae Bulbus, thrives in alpine meadows at altitudes of 2,800 to 4,400 m. In recent years, the rapid decline of wild plant populations, driven by rising market demand and global warming, has led to its classification as a rare and endangered species. This study utilized 83 distribution records of F. przewalskii and 39 climatic variables to assess its distribution range across different historical periods using an optimized MaxEnt model and analyzed the environmental factors affecting its distribution.
