The diurnal patterning of locomotion, stereotypy, grooming, eating, drinking, sleeping, postural readjustment, and inactivity was studied in 14 species of muroid rodents in the laboratory using a visual observation technique. Microtus canicaudus, M. montanus, M. ochrogaster, and M. pennsylvanicus exhibited acyclic activity patterns, while Peromyscus eremicus,

Open-field behavior was observed in 10-min tests of 10 males of each of eight taxa of muroid rodents. Results parallel those of an earlier study of muroid rodents by Wilson, · Vacek , Lanier, and Dewsbury (1976). Considerable variation among species was found for measures of locomotion, boli deposited, and most other behavioral patterns recorded. As in the Wilson et a1. (1976) study, animals displayed a strong tendency to seek walls. Correlation coefficients between measures of locomotor-exploratory behavior and number of boli are presented for 20 taxa of muroid rodents; no support is found for a negative correlation between these measures for these taxa.
