Published: Oct. 13, 2023

Primula filchnerae, an endangered plant endemic to China, has drawn people’s attention in recent years due its ornamental value flower. It was rarely recorded since being described 1902, but it rediscovered 2009 and is now known from a limited number of sites located Hubei Shaanxi Provinces. Since the species still poorly known, unanswered questions arise related it: How P. filchnerae responded past climate change how might respond future? Why filchmerae so collected during century? We assembled geographic coordinates for through field surveys website searches, then used maximum entropy model (MaxEnt) simulate potential suitable distribution six periods with varied carbon emission levels by combining bioclimatic environmental factors. MaxEnt showed that Min Temperature Coldest Month (bio6) Precipitation Quarter (bio19) affected filchnerae’s most, aggregate contribution >60% ranges above −5 °C below 40 mm, respectively. also analyzed habitat various differing impacts compared today’s habitats, most cases, Sichuan remained stable areas possible expansion north under scenarios, 2050s SSP5-8.5 scenario may be exception. Moreover, we evaluate population shifts, scenarios indicating geometric center would concentrated Province China. Finally, conservation strategies are suggested, including creation protected areas, long-term monitoring, raising public awareness conservation, situ measures, assisted migration, introduction.

Mountain apricot (Prunus sibirica) is an important fruit tree variety, and has a wide range of planting application value in China even the world. However, current research on suitable distribution area P. sibirica still inconclusive. In this study, we retrieved data for from Global Biodiversity Information Facility (GBIF), identified six key environmental factors influencing its through cluster analysis. Using these selected climate points China, applied maximum entropy model (MaxEnt) to evaluate 1160 candidate models parameter optimization. The final results predict potential under as well two future scenarios (SSPs126 SSPs585). This study shows that optimized with (AUC = 0.897, TSS 0.658) outperforms full using nineteen 0.894, 0.592). Under high-emission scenario (SSPs585), highly habitat expected gradually shrink towards southeast northwest, while expanding northeast southwest. After 2050s, habitats are projected completely disappear Shandong, new areas may emerge Tibet. Additionally, total increase future, more significant expansion (SSPs585) compared low-emission (SSPs126) (7.33% vs. 0.16%). Seasonal changes precipitation most influential factor driving sibirica.
