    "abstract": "We explore the complex dynamical behavior of simple predator-prey models of\nbiological coevolution that account for interspecific and intraspecific\ncompetition for resources, as well as adaptive foraging behavior. In long\nkinetic Monte Carlo simulations of these models we find quite robust 1/f-like\nnoise in species diversity and population sizes, as well as power-law\ndistributions for the lifetimes of individual species and the durations of\nquiet periods of relative evolutionary stasis. In one model, based on the\nHolling Type II functional response, adaptive foraging produces a metastable\nlow-diversity phase and a stable high-diversity phase.",
