Come out and see the Gray Lab if you are headed to the ICBF Conference this upcoming week! Dr. Suzanne Gray presents her research on the visual detection thresholds in walleye and their prey in algal and sedimentary turbidity in MacEwan Hall A on Tuesday, July 17th at 2:40 pm. Followed by Chelsey Nieman at 3:00 pm in MacEwan Hall A discussing her research on visual performance being impaired by elevated sedimentary and algal turbidity in Walleye (Sander vitreus) and Emerald Shiner (Notropis atherinoides). Tiffany Atkinson discusses the role of turbidity and diet on the reproduction traits of an African cichlid fish during her talk in the Bianca presentation room on Thursday, July 19th at 10 am. And lastly, Richard Oldham gives his talk on divergence in visual performance and morphology in an African cichlid found in divergent environments on Thursday, July 19th at 2:20 pm in the Bianca presentation room. Come out and listen!
One of my favorite parts of visiting Uganda is getting to work with local primary schools with our Water Across the World project. This project aims to teach students the importance of wetlands, forests, and aquatic organisms, and the role they play in water quality. This year we worked closely with the students and teachers from both St. Hildegard Primary School and the Lake Nabugabo Community Learning Center. They were all very excited to have us back to explore their water sources. We have also arranged the program to continue throughout the year, not just while we are there doing our fieldwork. Our amazing field staff, Mutebi, Kiberu, Ssegoya, and Geoffrey, will be working with these schools frequently so that they can begin to compile longer-term data from their local water sources. Some of the data they collect include: temperature, flow, water color, turbidity, and aquatic macro-invertebrates. I hope that by engaging students in this experiential learning process, I might be able to inspire some to become future scientists!
We spent yesterday with Nicole Hafer and her Muskingum Soil and Water Conservation District’s summer camp students! We have been working with these students for about four years now with our Water Across the World project where we connect them with grade school students in Uganda through videos and letters. Yesterday, we got to teach them a bit about water quality and aquatic organisms in the US as well as Uganda. We even had them lift a Jerri can to experience what retrieving water is like in Uganda vs. just turning on your tap at home. We also talked about the microsystis blooms that are currently plaguing Lake Erie and how it can affect Ohio’s water quality. Afterwards, we got to sample stream invertebrates and do a little fishing! Thanks so much Nicole and students for such a great experience!
We currently have Jeremy sampling differently managed agricultural ponds for water quality and fish and macroinvertebrate biodiversity; Bethany just returned from Uganda where she was investigating mate-choice between two populations of cichlids; Tiffany has been working on her cichlid diet analysis; Shib is dissecting eyes and brains of Round Gobies to look for parasites that cause cataracts; Chelsey is working closely with Lake Erie Charter captains to determine lure color choice of Walleye in different water conditions; Taylor has now reared 400 cichlids in the lab for behavioral studies under turbid and clear conditions; Andy is studying the optokinetic response of large Walleye under turbid conditions at Stone Lab; and Harrison is studying the swim performance of Emerald Shiners at Stone lab for his REU project. Quite the busy summer for the Gray lab! Stay tuned for weekly research spotlights on each project!
Our very own Dr. Gray was awarded the Alumni Award for Distinguished Teaching so CFAES interviewed her. Check out her interview here to find out more about her!
Congratulations to Richard Oldham who just had his first paper accepted in Current Zoology, “Behavioral differences within and among populations of an African cichlid found in divergent and extreme environments”. Richard performed this experiment as an undergraduate Research with Distinction project with The Gray Lab and The Pintor Lab!
Congratulations to Dr. Gray for receiving the Alumni Award for Distinguished Teaching! There were 200 nominations and only 10 professors were given the award this year. You work so hard everyday for all of your students and are so deserving of this award. You’re such a great role model for all of us!
Our very own undergraduate, Harrison Fried, presented his Honors thesis proposal, “How do algal and sedimentary turbidities affect the long-term physiology of Emerald Shiners in Lake Erie?” Great job Harrison! Outstanding undergraduate students in the School of Environment and Natural Resources at OSU are able to join our Honors program which allows students to complete an independent research project and defend a thesis which helps to prepare them for graduate studies!
