Mr. Rice,
I contacted you some time ago, probably nearly a
year ago by now, concerning F. cingulatus, F. rubrifrons, F.
auroguttatus. A colleague, Bob Cashner, and I had been working on
comparative genetic studies of the morphologically-based hypothesis that several
species were encompassed by the name F. cingulatus. We had collected very
strong genetic support for recognizing F. auroguttatus and F. rubrifrons and
were hoping to complete our work by increasing our sample sizes slightly, which
is what prompted me to contact you. I learned through the Native Fish
Conservancy that you were an expert on the ecology and distribution of these
species and had hoped that you could help identify potential collecting
localities.
What seemed to be a simple project that was
destined for rapid completion took an unexpected turn when I decided to
investigate alternative genetic markers that are more sensitive to population
divergence. Initially, this second data set confirmed what we had seen
with the first. However, I had difficulty completing the data set; western
Florida samples would not sequence. After manipulating my protocols and
finally generating sequences for the western populations, I discovered the
source of my problem - something completely unexpected and very exciting.
The western populations are genetically divergent, not to the same degree as
Apalachicola vs. peninsular populations but more than would have been
expected.
To make a long story shorter, we need additional
samples, more now than when I first contacted you. We would greatly
appreciate your help in identifying potential collecting localities for these
exquisite little killifishes, particularly in the central and western portions
of the panhandle and anything around the Suwannee R. drainage
basin.
Thank you for your assistance.
