Hi Gene,
My name is Matthew Johnston and I am a researcher/software developer with
the National Coral Reef Institute (NCRI) at the Nova Southeastern University
Oceanographic Center.  A colleague and I recently completed a lionfish fish
study that performed the precise analysis you are suggesting.  The resulting
article based on the results is currently available online in the journal
Marine Pollution Bulletin.
The basis for the study was straightforward; examine the temporal sequence
of historical lionfish captures/sightings and try to determine what factors
contributed to the pattern of invasion recorded in the records.  For this
study, we chose to use lionfish sighting/capture records from the USGS-NAS
(non-indigenous aquatic species) database which is the most complete
historical set of lionfish data currently available.  We then investigated
prevailing physical parameters at the locations where lionfish were found
(we used temperature, water depth, salinity, and ocean current, all obtained
from public record sets) and used a simple mathematical (cellular automata)
model to determine which of these factors had the most influence on the
spread of lionfish.  The resulting model output is a synthetic
representation of the current invasion which can then be used to predict
future invasions, or in the case of the current invasion, their eventual
trek into and throughout the Gulf of Mexico.  Our study also demonstrates
through a series of animations what would have likely occurred had the
invasion started in a different location such as the Gulf of Mexico or off
the coast of Colombia, South America.  Overall the results from our analysis
show that current was the overall largest parameter influencing the
distribution and eventual setting of lionfish.

There has been a lot of talk about connectivity lately. It was the
centerpiece of of the recent "Horizons Beyond" meeting at Mote Marine Lab.
Has anyone considered collecting all the Lion fish sightings data to use as
a metric for demonstrating connectivity? The larvae do follow the currents.
Just a thought. Gene
