Comprehensive Analysis of the Impact of Climate Change and Human Activities on the Distribution of Five <i>Fritillaria</i> Species Using the Optimized Maxent Model.

ABSTRACT: With climate change and the influence of human activities, species are likely to migrate or even go extinct. Five Fritillaria species, a well-known traditional Chinese medicinal plant, are rarer due to overharvesting. This study employed the Maxent model to identify suitable areas for the plant, determine key environmental factors, and project future shifts under three climate change scenarios. The analysis showed F. przewalskii and F. delavayi might migrate to higher elevations, while F. taipaiensis was expected to move to lower elevations. There were differences in the dominant environmental factors among different origins: F. cirrhosa (elevation, bio7, bio9, bio12, hfp); F. unibracteata (elevation, bio4, bio15, bio19, hfp); F. przewalskii
