FIGURE 6.
Pairwise comparisons of dietary niche breadth (effective number of taxa; 1D; Hill, 1973) of salt marsh harvest mouse (Reithrodontomys raviventris; RERA), western harvest mouse (R. megalotis; REME), house mouse (Mus musculus; MUMU), and California vole (Microtus californicus; MICA). Comparisons were conducted pairwise because sample sizes of non‐RERA were inconsistent throughout space and time, therefore only allowing valid comparisons at a different suite of sites/seasons for each species pair. RERA/REME comparisons were conducted at Goodyear Slough (GYS) in summer, fall, and winter; RERA/MUMU comparisons were conducted at GYS (summer and fall), Hill Slough wildlife area ponds 1&2 (summer) and EDEN landing ecological reserve (EDEN; spring); and RERA/MICA comparisons were conducted at GYS (summer and spring) and EDEN (spring)
