[apologies for crossposts!]
Dear colleagues:
Hello! By way of introduction, I am a graduate student at Florida State
University in Tallahassee. My research revolves around the evolution and
ecology of commensalism, and I'm using pea crabs (Brachyura:
Pinnotheridae) as a model system. Several species of pea crabs are
annelid symbionts, and I write to you with the hope that you might be able
to help me collect pea crab specimens for gene sequencing and
phylogenetic analysis.
Several pea crab species in the genus Pinnixa are associated with
annelids, typically polychaetes. Most live as inquiline residents of worm-
constructed burrows. It is my hope that some of you will be familiar with
these crabs, even simply as "incidental" symbionts of the vermiferous taxa
with which you work.
If you would be willing to collect crabs, or know of someone who might,
please contact me. I've included a complete list of "wanted" taxa below,
with hosts and species ranges where known. I've included the genera
Dissodactylus, Clypeasterophilus, and Fabia as well, even though they are
bivalve or echinoderm symbionts; please feel free to distribute this list to
colleagues who work with other host taxa!
Thank you in advance for any help you can offer! Ideally, collected
specimens should be 'fixed' in 70-100% ethanol (formaldehyde makes
genetic work impossible). I would be happy to reimburse you for the cost
of materials and shipping, and I would be more than willing to 'trade' local
molluscan specimens from the northern Gulf of Mexico. Good advice -
particularly about other researchers who might be able to help me - would
also be most welcome!
With best regards,
