Understanding the ecological effects of fire is important for biodiversity conservation in flammable ecosystems. To this end we quantified the winter and spring diet of silky mice (Pseudomys apodemoides) and heath rats (P. shortridgei) at 20 woodland sites ranging from 2 to 55 years post-fire. We tested the hypothesis that diets would differ (shift) between very recently burnt (2-3 years old) and mature (≥17 years old) parts of the landscape. Analyses based on faecal material collected in winter (June) and spring (October) demonstrated that both species ate a broad range of foods, but the diets of silky mice and heath rats differed substantially with respect to monocot, seed and invertebrate..View full abstract
