[Objectives] The introduction of Silver Foxes (Vulpes vulpes) as a natural predator is one of the biological control measures against Plateau Pika (Ochotona curzoniae). Investigating the survival status of artificially released Silver Foxes is crucial for assessing their effectiveness in rodent control. [Methods] This study was conducted in the Plateau Pika distribution areas of Xiahe, Luqu, and Maqu counties in Gannan Prefecture, China. In October 2019 and October 2022, a total of 13 Silver Foxes equipped with GPS+VHF tracking collars were released in the field. The abiotic factors (climatic factors, terrain factors, and distance from water source) and biotic factors [normalized difference vegetation index (NDVI) and human disturbance factors] were obtained from the location data transmitted by the tracking devices. Correlation and multivariate stepwise regression analyses were performed to analyze the survival duration of Silver Foxes and clarify the relationships between their survival duration and ecological factors. ArcGIS 10.2, SPSS 27, Origin 2022, and Excel 2019 were used for data analysis and chart production. [Results] (1) Among the 13 released individuals, five (38.46%), six (46.15%), and two (15.38%) survived less than one month, 2 ~ 3 months, and more than six months, respectively (Table 2). (2) The survival duration was positively correlated with mean annual temperature (r = 0.62, P < 0.05, Fig. 3a) and negatively correlated with elevation (r = -0.62, P < 0.05, Fig. 2a) and humidity (r = -0.70, P < 0.05, Fig. 3b). Although survival duration was negatively correlated with NDVI, distance from water source, distance from residential area, and distance from road, these relationships were not statistically significant (Figs. 4, 5). (3) Multivariate stepwise regression analysis further identified humidity as the key ecological factor, which explained 56.60% of the variation in survival duration (Table 3). [Conclusion] The survival capacity of artificially released Silver Foxes is relatively limited, and under winter (October) release conditions, ambient humidity is the main factor constraining their survival duration.
