argh. Not sure if I addressed this right the first time - apologies if
you get this twice...

True, although to be fair they authors were attempting to hold
resource distribution constant (and fairly plentiful).  If you have to
walk anyways between bites, then a long neck is even less useful for
browsing.

This is true if you have a mean spacing between plants longer than the
neck, but not necessarily if the mean spacing is lesser than the neck
of the long-necked animal but longer than the neck of the
short-necked.
For the productivity available to the sauropods to limit their energy
expanditure you not only need to invoke habitats with low plant
density, you may also take into account limited distributions with

Or low quality?
