The purpose of this study was to measure the effects that toxicosis had on the hamster's predatory behavior and to compare these results with those found in previous studies with grasshopper mice. A 0.15 M LiCl injection caused hamsters to develop a greater aversion and to inhibit their feeding and attack responses more frequently toward a house cricket(More)
This study examined the grasshopper mouse's use of visual cues to recognize a potential prey. The mouse's latency of attack was measured in response to models presented in five experiments. The mice responded to the contrast, movement and relative size of a visual stimulus, but did not respond to different orientations or shapes. Furthermore, the mice did(More)
The responses toward denatonium saccharide and quinine by three rodent species differ from those exhibited by humans. This study measured the relative aversiveness of these two compounds in grasshopper mice (Onychomys leucogaster) to determine if this species responded similarly to or differently from these other rodents. In a choice test, the mice clearly(More)
This study examined the relative importance that olfaction, audition and vision played in the spiny mouse's localization of insect prey. These three senses were blocked singly or in various combinations so that a mouse was tested under 8 different situations with a tethered live cricket and four with a dead cricket. The mice did not rely on one particular(More)
This study examined the effect that toxicosis paired with the presence of a distinctive texture had on the inhibition of the grasshopper mouse's predatory attack. The first experiment measured the context in which tactile cues would be most effective by presenting prey with various combinations of added stimuli. The combination of distinctive tactile,(More)
This study examined the relative importance vision, audition and olfaction played in the localization of prey in the golden hamster (Mesocricetus auratus ). These three senses were blocked singly or in various combinations so that a hamster was tested under eight different situations with a tethered cricket and four situations with a dead cricket. Vision,(More)
This study examined the development of olfactory recognition of an insect prey by the northern grasshopper mouse. The approach was to feed different groups of mice a certain amount of house crickets, may beetles or mealworm larvae or varying numbers of house crickets and then measure a mouse's preference for discovering that particular species when(More)
