Grasshopper susceptibility to predation in response to vegetation cover and patch area
Journal of Orthoptera Research 5, 175-184
Abstract: An individual's risk to predation is influenced by the foraging strategies of its predators, its own anti-predator mechanisms, and the physical characteristics of its habitat. In this study, three grasshopper species (Amphitornus coloradus, Ageneotettix deorum, and Melanoplus sanguinipes) were tethered and placed in single grasshopper species patches of 10, 20, and 30 individuals in two different habitats to examine factors that affect grasshopper susceptibility to predation. Species tended to be less susceptible to vertebrate predation in areas most similar to their naturally chosen microhabitats. M. sanguinipes was less susceptible to vertebrate predation than either A. deorum or A. coloradus.
