A successful OU BIO EXPO yesterday!

Our lab group was one of many Biology Department labs that participated in the 1st annual OU BIO EXPO held in the Beaird Lounge of the Oklahoma Memorial Union.   We want to thank the dedicated staff of the Dept. of Biology for organizing such a great outreach event!

Matt Wersebe, Kaylee Gibbons and Juliet Agadagba show interested students the type of work we do in our lab at the OU BIO EXPO – 7 Nov. 2019.

2019 ESA Simberloff Award to Emily Kiehnau!

 

 

We want to share some exciting news from Emily Kiehnau. She just received word that she is the recipient of the Ecological Society of America (ESA) Invasion Section’s 2019 Simberloff Award for Outstanding Student Presentation (oral presentation) at the 2019 meeting, which was held last month in Louisville. She presented results from her 2nd Chapter of her dissertation (entitled “Morphological changes of native Daphnia species in response to the invasive predator Bythotrephes longimanus“).  Please join us in congratulating Emily on a job well done!

Welcome to all the new members of the lab!

We would like to welcome our new lab members, Juliet Agadagba, Kaylee Gibbons, and Amber Woolley, who will all be conducting Independent Research in our lab, this academic year!

Congratulations to Rachel Hartnett!

Former lab member/doctoral student, Dr. Rachel Hartnett has published a paper in Royal Society Open Science entitled “Variation in life-history traits among Daphnia and its relationship to species-level responses to phosphorus limitation”.  This represents a portion of her dissertation (“Theoretical and empirical studies on hierarchical effects of size distributions: Linking the individual to its community”).  Please visit Rachel’s website  for more information about her current research projects.  Congratulations again, Rachel!

Fun with mud in Minnesota!

We just returned from an intense week of sediment core sampling of lakes around the Twin Cities (MN) region, as part of the dissertation research of Matt Wersebe.  Now, the fun begins with analyzing all of the mud samples.  We thank our collaborator/colleague Dr. Mark Edlund for his kind hospitality during our stay at the St. Croix Watershed Research Station (Science Museum of Minnesota).

Another successful academic year comes to an end!

Another successful OK Science Fest outing!

Just wanted to thank everyone again for their hard work at the 2019 OK Science Fest yesterday at the State Fairgrounds in OKC.  I think our “Life-in-a-Pond” live display, along with the “Predator-Prey Game-of-Tag”, was a resounding success (see the Outreach Page for more photos).
