Laboratory Tests of Species Discrimination in Three Species of Peromyscus
Species discrimination by Peromyscus boy Hi (brush mouse), P. manicu- latus (deer mouse), and P. californicus (California mouse) was investigated in the laboratory using a computerized data collection system that recorded time spent adjacent to each of two stimulus mice. In tests between P. maniculatus and P. boylii, male and female P. boylii chose significantly to spend more time adjacent to the conspecific stimulus mice. Other groups of test mice did not spend signif- icantly more time next to either stimulus mouse. Behavioral differences in relation to captivity may be correlated with differences in tendency to associate with conspecifics in laboratory experiments.
