    Linking spatial patterns of terrestrial herbivore community structure to trophic interactions

    Jakub Witold Bubnicki et al.
    The spatial interactions between humans, large carnivores and herbivores cascade down in a complex but predictable way to lower trophic levels affecting regeneration of tree species in a temperate forest.

    First bone-cracking dog coprolites provide new insight into bone consumption in Borophagus and their unique ecological niche

    Xiaoming Wang et al.
    Fossilized feces (coprolites) of extinct bone-crushing dogs, Borophagus parvus, from late Miocene (6 million years ago) of California demonstrates consumption and preservation of bones in digestive tracts and potential social hunting behavior by these predators.

    Tooth fracture frequency in gray wolves reflects prey availability

    Blaire Van Valkenburgh et al.
    Despite risks of infection and reduced fitness, tooth fracture frequency in gray wolves increases rapidly when prey are scarce because they must consume carcasses more completely.
