Molecular dietary analysis of the Sorex cylindricauda and Sorex bedfordiae in the Mount Emei. Arthropoda

To understand the coexistence mechanism of closely related species with homologous distribution, this study used DNA metabarcoding technique to analyze the molecular diet of the stomach contents of the Sorex cylindricauda and Sorex bedfordiae in Emei Mountain, Sichuan, to analyze the characteristics and seasonal patterns of its food composition throughout the year, and to calculate and compare the interspecific food diversity, ecological niche width and overlap index
