  • Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

    Creator:
    Coblentz, Kyle E.
    Abstract:
    Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

  • Quantifying predator dependence in the functional response of generalist predators

    Creator:
    Novak, Mark, Wolf, Christopher, Coblentz, Kyle E., and Shepard, Isaac D.
    Abstract:
    A long-standing debate concerns how functional responses are best described. Theory suggests that ratio dependence is consistent with many food web patterns left unexplained by the simplest prey-dependent models. However, for logistical reasons, ratio dependence and predator dependence more generally have seen infrequent empirical evaluation and then only so in...

    Simulations of combustion and reacting flows often encounter stiffness in the equations governing chemical kinetics. Explicit solvers for these ordinary differential equations offer low computational expense, but typically cannot efficiently handle stiff systems. In contrast, implicit methods demand greater expense but offer unconditional stability—as a result, most reactive-flow solvers rely...
