The mass and speed of quadrupedal rodents


In an investigation of the relationship between mass (kg) and speed (km/hr) in mammals, Garland (1983) collected information from published articles on these two variables for a large number of different species. These measurements are given below for a variety of four-footed rodents. (The common names of the species are taken from Corbet & Hill (1986).) Notice that the measurements are not all recorded to the same level of accuracy since the results have been collated from the work of a number of different scientists.

The data are used in rp.cartoons.
