    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 ...
