Applying the BFQ normalizes the data allowing for fair comparison between species of different sizes in much the same way as an encephalization quotient normalizes data for brain size to body mass comparisons. Consequently, small species would be expected to bite harder for their size than large species if a simple ratio of bite force to body mass is used, resulting in bias. All else being equal, it would be expected to follow a 2/3 power rule. Because body mass is proportional to volume the relationship between bite force and body mass is allometric. The authors predicted bite forces using beam theory, based on the directly proportional relationship between muscle cross-sectional area and the maximal force muscles can generate. Results showed that predators that take relatively large prey have large bite forces for their size, i.e., once adjusted for allometry. (2005) in a paper comparing bite forces, body masses and prey size in a range of living and extinct mammalian carnivores, later expanded on by Christiansen & Wroe (2007). The BFQ is calculated as the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms. Wikipedia Rate this definition: 0.0 / 0 votesīite force quotient (BFQ) is a numerical value commonly used to represent the bite force of an animal, while also taking factors like the animal's size into account.
