Digital field work: the next step?

Bill Frank has already been doing some very clever detective work in and around Jacksonville, Florida on the occurrence of Bulimulus aff. sporadicus (e.g., here and here). Today his next message read: “Was using Google Street View this afternoon on my computer to “drive” or maybe I should say “mouse” around Jacksonville looking for Bulimulus sporadicus. Much to my surprise I found a location where it appeared that Bulimulus were present but the Google imagery wasn’t high enough in resolution to be absolutely sure plus the imagery was dated April, 2013.

Although in the past I have used Street View to view snails after I had first visited the location and confirmed their presence, today’s find, if confirmed by an on site visit, would be the first time that snails would were found solely based upon street view. So I jumped in the car and drove downtown to the location in question which is on Deer Street underneath the US-1 overpass. Upon arrival I found Bulimulus in the exact location as depicted in Street View on the concrete wall in somewhat modest numbers. However on the other side of the road live specimens were present in large numbers on another concrete wall. After looking around for a bit I changed my estimation from hundreds to probably tens of thousands of snails being present. The ground was just white with empty shells and represents the most specimens I have ever seen at a single location which is really saying something. This location within the past couple of  years has undergone a complete transformation due to road/overpass construction which makes the find all that more impressive (i.e. the snails had accomplished this in a relatively short period of time)”.

So one might ask, will malacological field work turn into a digital exercise? Perhaps the saying of football coach Johan Cruijff may be apt in this context… “Je ziet het pas als je het doorhebt” [you see it when you get it]. Bill’s previous experience undoubtedly helped him a lot, but still: Chapeau for this digitally savvy malacological detective!
