Introduction The fungus Cordyceps cicadae is both edible and medicinal. Methods To acquire a thorough comprehension of its distribution in China, two host insects, Macrosemia pieli Platypleura kaempferi , were selected as biological factors potentially associated with distribution, the ENMTools program was utilized to ascertain principal environmental affecting suitable habitats. possible geographic distributions present well 2030s, 2050s, 2070s then predicted using optimized MaxEnt model. Results primary variables soil pH, mean diurnal range, annual precipitation, precipitation seasonality, temperature driest month. C. thrived on steep slopes. some which also significantly affect hosts. Most habitats M. currently found subtropical monsoon zone. SSP126, SSP370, SSP585 scenarios positive, stable, unfavorable impacts extent for respectively, suitability P. decreased under three different conditions. expansion observed provinces bordering middle lower reaches Yellow River, Zhanjiang, Guangdong Province, northern Yunnan Province. Conversely, habitat contraction mainly western Guangdong, southern Guangxi, Hainan, southwestern Yunnan, areas eastern Sichuan. shared regions hosts primarily located Moreover, future centroids at higher elevations than ones Jiangxi Hunan. Discussion In light climate change, this research held significance conservation sustainable utilization .

The Wushan Salamander (Liua shihi), Jinfo (Pseudohynobius jinfo), and Wenxian Knobby (Tylototriton wenxianensis) are rare national Class II protected wild animals in China. We performed MaxEnt modeling to predict analyze the potential distribution trends of these species Chongqing under current future climate conditions. Species data were primarily obtained from field surveys, supplemented by museum collections existing literature. These efforts yielded 636 records, including 43 for P. jinfo, 23 T. wenxianensis, 570 L. shihi. Duplicate records within same 100 m × grid cell removed using ENMTools, resulting 10, 12, 58 valid points shihi, respectively. optimization feature class parameters (FC) regularization multiplier (RM) applied R package “ENMeval 2.0” establish optimal model with MaxEnt. refined models simulate suitable areas three species. results indicate that habitat area shihi accounted 9.72% whole region municipality. It is projected that, 2050, proportion will increase 12.54% but decrease 11.98% 2070 further decline 8.80% 2090. jinfo 1.08% municipality, which expected 0.31%% 0.20% 2070, 0.07% wenxianensis 0.81% anticipated 0.37% 0.21% 0.06% Human disturbance, variables, characteristics primary factors influencing salamander Chongqing. proximity roads significantly impacts while conditions mainly affect distance water sources crucial wenxianensis. following suggestions made based on key variables identified each species: (1) For it imperative minimize human disturbances preserve without vegetation nature reserves ensure their continued existence. (2) conservation high-altitude habitats utmost importance, along reduction caused maintain species’ ecological niche. (3) protection aquatic crucial.
