1/15/2014 Ordovician Atlas expands!  

 

I am always seeking motivated students, both undergraduates and potential graduate students, to join my research group.

Research projects are available in GIS-based paleobiogeography, phylogenetic systematics of brachiopods, and taphonomy and evolution of crustacean taxa. Interested students should contact me directly at stigall@ohio.edu.

Graduate funding through Teaching and Research Assistantships is available through the NSF grant funding and the Department of Geological Sciences. More info.

 
The Stigall lab (or as we sometimes call them: the Stig-All Stars) have been working super hard to populate species and higher taxa page in the Ordovician Atlas with a goal of having all the top 50 species up by the end of the month. They are doing a tremendous job! There are currently 32 species--in 5 phyla live!      
       
1/1/2014 New year, new publications      
Lots of exciting new research is coming out from the Stigall lab this month: more niche modelling, more brachiopod phylogenetics, and even a new species of conchostracan!      
       
10/15/2013 Geological Society of America      
As usual, Ohio University's paleontology program was well represented at the GSA meeing-11 presentations total! Five involved members of the Stigall lab. Perhaps most excitingly, we rolled out our new outreach website on Cincinnatian fossils: www.ordovicianatlas.org      
       
7/15/2013 New PLoS ONE paper on Ordovician speciation
Now that the phylogenetic analyses from Davey's thesis are in press (with Journal of Paleontology and Journal of Systematic Palaeontology), we were able to publish the phylogenetic biogeography paper that builds on those analyses. This analysis uncovered a dramatic shift in speciation style (from vicariance to geodispersal) associated with the M4/M5 sequence boundary, shift in tectophases, and GICE excursion. Really interesting stuff! We hope to expand this analysis with more phylogenies as they become available from our lab and others (paging alumnus Rob Swisher...)
 
6/24/2013 SILAS workshop
This week, I had the priviledge to work with a group of 22 science teachers in a program co-led by OU Department of Education faculty to enhance science literacy in Appalachian Ohio. I developed units based on deep time, fossils of ohio, and plate tectonics. It was inspiring to spend time with such dedicated educators.

 

6/10/2013 IGCP 591 Meeting: Lund, Sweden
This year, the annual meeting for IGCP 591 (Early to Middle Paleozoic Revolution) was held in Lund, Sweden. I spoke about our work on niche evolution during the Richmondian Invasion. The talk was well recieved and the opportunities to engage with international colleagues at the meeting was tremendous. So many talented brachiopod workers! (sad that there are so few of us in the US...)
 
7/5/2013 Exciting spring and summer

I am woefully behind on reporting the truly exciting goings on in the lab. This spring I was on sabbatical, but my students "held down the fort" in impressive fashion!

Hannah completed her thesis, won the outstanding graduating student award, submitted and had her thesis research accepted for publication in Paleobiology. She also completed digitizing the Kallmeyer collection, with the assistance of Diane and Cody, and has spent the summer building incredible content for the bryozoan pages of the Digital Atlas of Ordovician Life. I will really miss her enthiastic presence and general awsomeness in the lab.

Jen made visited the Peabody Museum and National Museum of Natural History Collections (twice) to gather data for her revision of Eochonetes/Thearodonta. She also recieved a very prestigious teaching award from Ohio University, the outstanding TA award, and three grants to fund her research. Congratulations, Jen!

 
2/11/2013 AAAS Meeting and Ithaca's Darwin Days

11/15/2012 Busy and productive fall!
The Stigall lab has been busy this fall. We welcomed our new grad student, Jennifer Bauer, to the group. Hannah and I traveled to Kansas for a PaleoNICHES working group meeting. We have been designing and implementing a new museum database for our collections. We presented a talk and two posters at GSA in Charlotte. One new paper was published. And we've been busy analyzing data, revising text, and teaching classes. Busy, busy, busy.
 
6/1/2012 End of year accolades
The Stigall lab typically shines at the Geological Sciences end of year picnic, but the lab's showing year was particuarly strong. Davey won the Outstanding Graduate Student Award. Hannah was presented the Outstanding TA Award. Sierra won Oustanding graduating senior, and new lab member Diane Estes was awarded the Distinguished Professor Scholarship. Working with these talented students is the key reason that I was able to walk away with the Outstanding Faculty Research Award.
