    A mast-seeding desert shrub regulates population dynamics and behavior of its heteromyid dispersers 

    Auger, Janene; Meyer, Susan E.; Jenkins, Stephen H. (2016)
    Granivorous rodent populations in deserts are primarily regulated through precipitation-driven resource pulses rather than pulses associated with mast-seeding, a pattern more common in mesic habitats. We studied heteromyid ...

    Orienting the Interaction Compass: Resource Availability as a Major Driver of Context Dependence 

    Pringle, Elizabeth G. (2016)
    Life on earth is enormously diverse, in part because each individual engages in countless interactions with its biotic and abiotic environment during its lifetime. Not only are there many such interactions, but any given ...
