The intensity and character of the overtone harmonic series is different depending on scale length. Longer scaled basses emphasize the overtone series more than shorter scaled basses. So, generally, the fundamental will be more pronounced on a short scale bass compared with a longer scaled bass.
The loudest part of a note played in first position on a 34" scale bass comes from the second order harmonic, and not from the fundamental. This largely explains why longer scaled basses sound clearer and more mid-rangey than shorter scaled basses that sound more deep, dark, and muddy.
The band Brazilian Girl's bass player Jesse Murphy plays a Fender Mustang bass, short-scaled, and it is a really great example of the unique deep tone that a shorter scale provides, IMHO.

Pickup placement plays a big part in this as well. If a pickup is nearer to the node for the second order harmonic for a specific note being fretted, then that tone will be quieter than it would be if the pickup was located at the trough for the second order harmonic for that same fretted note.
