Response of distribution patterns of two closely related species in Taxus genus to climate change since last inter‐glacial

Climate change affects the species spatio‐temporal distribution deeply. However, how climate affects the spatio‐temporal distribution pattern of related species on the large scale remains largely unclear.

Description
Summary:Climate change affects the species spatio‐temporal distribution deeply. However, how climate affects the spatio‐temporal distribution pattern of related species on the large scale remains largely unclear. Here, we selected two closely related species in Taxus genus Taxus chinensis and Taxus mairei to explore their distribution pattern. Four environmental variables were employed to simulate the distribution patterns using the optimized Maxent model. The results showed that the highly suitable area of T. chinensis and T. mairei in current period was 1.616 × 105 km2 and 3.093 × 105 km2, respectively. The distribution area of T. chinensis was smaller than that of T. mairei in different periods. Comparison of different periods shown that the distribution area of the two species was almost in stasis from LIG to the future periods. Temperature and precipitation were the main climate factors that determined the potential distribution of the two species. The centroids of T. chinensis and T. mairei were in Sichuan and Hunan provinces in current period, respectively. In the future, the centroid migration direction of the two species would shift towards northeast. Our results revealed that the average elevation distribution of T. chinensis was higher than that of T. mairei. This study sheds new insights into the habitat preference and limiting environment factors of the two related species and provides a valuable reference for the conservation of these two threatened species. For T. chinensis and T. mairei, temperature and precipitation are the dominant factors limiting their distribution area. The distribution region of the two species was almost in stasis from LIG to the future periods. T. chinensis is mainly distributed in Sichuan Basin and surrounding mountains, and T. mairei occupies most of the mountain areas in eastern and central China.
