Data from: Abiotic conditions mediate intraguild interactions between mammalian carnivores ...
1. Intraguild (IG) interactions are common among mammalian carnivores, can include intraguild predation (IGP) and interspecific killing (IK), and are often asymmetrical, where a larger more dominant species (IGpredator) kills a smaller one (IGprey). According to ecological theory, the potential for...

| Summary: | 1. Intraguild (IG) interactions are common among mammalian carnivores, can include intraguild predation (IGP) and interspecific killing (IK), and are often asymmetrical, where a larger more dominant species (IGpredator) kills a smaller one (IGprey). According to ecological theory, the potential for a IGpredator and IGprey to coexist depends on whether the direct consumptive benefits for the IGpredator are substantial (IGP) or insignificant (IK), the extent to which the IGprey is the superior exploitative competitor on shared prey resources, and overall ecosystem productivity. 2. We used resource selection models and spatially-explicit age and harvest data for two closely related mesopredators that engage in IG interactions, American martens (Martes americana; IGprey) and fishers (Pekania pennanti; IGpredator), to identify drivers of distributions, delineate areas of sympatry and allopatry, and explore the role of an apex predator (coyote; Canis latrans) on these interactions. 3.
