Prediction of the potential geographic distribution of the ectomycorrhizal mushroom Tricholoma matsutake under multiple climate change scenarios

ABSTRACT

Effective conservation and utilization strategies for natural biological resources require a clear understanding of the geographic distribution of the target species. Tricholoma matsutake is an ectomycorrhizal (ECM) mushroom with high ecological and economic value. In this study, the potential geographic distribution of T. matsutake under current conditions in China was simulated using MaxEnt software based on species presence data and 24 environmental variables. The future distributions of T. matsutake in the 2050s and 2070s were also projected under the RCP 8.5, RCP 6, RCP 4.5 and RCP 2.6 climate change emission scenarios described in the Special Report on Emissions Scenarios (SRES) by the Intergovernmental Panel on Climate Change (IPCC). The areas of marginally suitable, suitable and highly suitable habitats for T. matsutake in China were approximately 0.22 × 106 km2, 0.14 × 106 km2, and 0.11 × 106 km2, respectively. The model simulations indicated that the area of marginally suitable habitats would undergo a relatively small change under all four climate change scenarios; however, suitable habitats would significantly decrease, and highly suitable habitat would nearly disappear. Our results will be influential in the future ecological conservation and management of T. matsutake and can be used as a reference for studies on other ectomycorrhizal mushroom species.

Mentions: The model results indicated two main regions of T. matsutake distribution (Fig. 2): northeastern China, which includes Heilongjiang and Jilin provinces, and southwestern China, which includes Yunnan Province, Sichuan province, the Tibet Autonomous Region, and Guizhou province. The calculated areas of the marginally suitable, suitable, and highly suitable habitat of T. matsutake in China are approximately 0.22 × 106 km2, 0.14 × 106 km2, and 0.11 × 106 km2, respectively. The suitable and highly suitable habitats are mainly located in southeastern Heilongjiang, northeastern Jilin, central and southern Sichuan, southeastern Tibet, northern and central Yunnan and their surrounding areas. The largest area of highly suitable habitat occurs in Sichuan and Yunnan and covers an area of approximately 0.094 × 106 km2, accounting for 87% of the highly suitable habitats in China.
