This study examines the occurrence, impact and implications of tamarisk invasion in the Finke River. We consider that the key factors in maintaining or changing the composition and structure of the
Effect of grazing by cattle on the abundance of grasshoppers on fescue grassland.
If different intensities of grazing affect the densities of various species of grasshoppers on native fescue rangeland is determined to determine if changes in the vegetative cover should result in changes in grasshopper populations.
Utilization of Food Plants by the Migratory Grasshopper, Melanoplus Bilituratus (Walker) (Orthoptera: Acrididae), with Some Observations on the Nutritional Value of the Plants
Grasshoppers were fed individually on either wheat, western wheat grass, or oats for 40 days after hatching, and the various criteria indicate that wheat is a good food; that oats is a poor food only because the grasshoppers do not eat enough; and that western Wheat grass is apoor food, possibly because of a deficiency in nutrients.
