"behavioral variation" is a correct and usable phrase in written English.
You can use it when referring to changes in behavior between individuals of the same species. For example, "The behavioral variation among different species of chimpanzees is an important area of study in the field of primatology".
An assumption of typical adaptive behavior models is that behavioral variation among individuals is negligible or such variation does not affect community dynamics.
Although there is a heritable basis for many animal behaviors, the genetic architecture of behavioral variation in natural populations remains mostly unknown, particularly in vertebrates.
There were also some unexplained reactions, affirming LSD's capacity to trigger infinite behavioral variation.
Sometimes, however, the researcher must experimentally enhance behavioral variation where too little exists in nature.
And although humans do not dig burrows, that, said the leader of the three-person research team, Hopi E. Hoekstra of Harvard, could "tell us something about behavioral variation in humans".
However, the mechanisms that give rise to this behavioral variation are often unclear.
Behavioral variation is often accompanied by morphological adaptations that increase the efficiency of a given tactic.
In doing this, we have attempted to emphasize that behavioral variation and fitness have a necessary relationship.
Furthermore, elasmobranchs exhibited significant behavioral variation towards magnetically-treated baits, in comparison to baited controls and procedural controls.
Insects and other arthropods provide ideal model systems to study how intraspecific behavioral variation affects phenomena in ecology.
Archaeology is a sub-discipline of anthropology, which is the study of people, particularly human biological and behavioral variation in the present, as well as the past.
