A baseline is a hypothesis of historical relationship between the origin
and evolution of a track (individual or standard) and the baseline feature
crossed by the track.

Perhaps the best way to address this problem is to apply the method. I can
answer specific questions at the point where there is a perceived problem.

I don' think ecological screening is an assumption in panbiogeography.
