- ... The inability to maintain signal detection performance with time on task, or response decrement, has been widely studied. In animals with small brains, the ability to filter out repetitive, irrelevant stimuli may prevent the nervous system from being saturated with information. However, animals must be particular to which stimuli they attend and those to ignore, as mistakes may be costly. We explo ...

- ... Ecological performance in animals is considered to be constrained by trade-offs between structural and physiological features. Some of the best anatomical and physiological data in support of this perspective are based on findings from canines, in which researchers have demonstrated skeletal shape trade-offs between running efficiency and strength. There has, however, actually been little examinat ...
