Chris,
I am comparing individuals with very different home range sizes.
I can see 4 ways (not mutually exclusive) that animals can
increase home range size: Individuals could (1) spend more time
traveling, (2) travel faster (3) travel in a straighter path at a
small scale, and (4) travel in a straighter path at a larger scale
(of course, I'm assuming that there are only 2 scales of
interest).
I can estimate (1) by classifying active vs inactive time periods, I can estimate (2) with speed, and (3) with Tau velocity. But what would be a good estimate for (4)? It would have to be independent of the other 3.
Thanks, Vilis

Chris,
Thanks, these are helpful.
Also, what you said about the the structure of the movement
models is interesting. If the OUF is fractal as you resolve
coarser than tau[velocity], then what happens at >=
tau[position]?
Thanks, Vilis

Chris,
What parameter(s) determine the tortuousity of the fractal path
between the resolutions of tau[velocity] and tau[position]?
Hi Vilis,

Chris,
tau[velocity] affects tortuousity, but it is also the timescale
for persistence of motion. These two seem to be different things -
i.e. could there be a specific tau[velocity], below which the path
is straight, but above which there are different values of path
toruousity?
Thanks, Vilis
