COVER PHOTO: Davies et al. (this issue; Article e03319; doi:10.1002/ecy.3319) investigated how African wild dogs, which are competitively inferior to lions and frequently killed by them, coexist with lions in a landscape where both carnivores are present at exceptionally high densities. They found wild dogs are able to exploit the heterogeneous landscape of the study region to avoid detection by lions, providing evidence for spatial heterogeneity being a mechanism for carnivore coexistence.
