Abstract:
Southern grasshopper mice (Onychomys torridus) were allowed to junt buried mealworms in a laboratory arena. The prey were arranged in two patterns, one aggregated and one relatively dispersed. Mice captured more prey from the dispersed treatment in the 2 h experiment, a result that can be attributed to both the greater ease of finding the first prey and a more efficient style of search for dispersed prey.
