Research in our group also involves theoretical work related to searching behavior and foraging modes (The American Naturalist 168: 350-357; The American Naturalist 172: 596–598; Evolutionary Ecology 23: 245-259; Population Ecology 54: 187-196), interference competition among foragers (Population Ecology 50: 319-324), effects of individual size variation on population dynamics (The American Naturalist 170: 719-733; Journal of Orthoptera Research 17: 283-291) and on community structure (Ecological Modelling 206: 119-130), and consequences of variation in male harem size on population persistence of Bengal tigers (Biological Conservation 147: 22–31).
