Table 4. Regression models for relationships between IV in Black-backed jackal diet in the Maria Moroka Nature Reserve, Free State Province: Implications for managing depredation on small stock farms

Table 4. Regression models for relationships between IV (Importance Value) values of the three major prey types used by Black-backed jackals at Maria Moroka Nature Reserve through the study period. Best-fit models have the lowest AIC c scores. Significant effects (p <0.05) are highlighted in bold typeface.
