Wagner, meanwhile, is entering her fourth year in a genome biology and physiology program and is a member of&nbsp;St. Michael鈥檚 College.</p> <p>鈥淭his has been my first real experience doing research,鈥 says Peters. 鈥淚'm planning to do a master鈥檚 degree or PhD, so I wanted to see if research was for me and see what type of research I liked. I wanted to get a feel for how this type of research is done.鈥</p> <p>Wagner, for her part, says she is interested in genomics and wants to pursue a career in genetic counseling.&nbsp;鈥淥ur project is related to uncovering how different characteristics correlate with different gene variations and how common these variations are in a population 鈥 so it was just what I was looking for,鈥 she says.</p> <p>The students鈥&nbsp;REP supervisor is&nbsp;<strong>Arthur Weis,</strong> a professor in the Faculty of Arts &amp; Science鈥檚&nbsp;department of ecology and evolutionary biology. Weis studies natural selection 鈥 one of the mechanisms by which species evolve 鈥 in particular, when evolution occurs over a short period of time.</p> <p><img alt src="/sites/default/files/wagner-629-crop.jpg" style="width: 750px; height: 500px;"></p> <p><em>Abigail Wagner 鈥渂ags鈥 a gall to protect it from parasitic wasps&nbsp;(photo by Kemeisha McDonald)</em></p> <p>The goldenrod fly is a parasite that lays its eggs on goldenrod plants. After about 10 days, a larva emerges from the egg and burrows into the plant鈥檚 stem, triggering the growth of a gall 鈥 a round, tumour-like sphere measuring a half-inch to an inch in diameter. The larva survives the winter inside the gall and in the spring, the adult fly emerges, ready to start the cycle over.</p> <p>Peters and Wagner are helping Weis in his research into the genetic connection between individual flies and the size of the galls their larvae produce.</p> <p>Gall size is important. Larvae in small galls are vulnerable to parasitic wasps that lay eggs in galls which then hatch into larvae that prey on the fly larvae. Larger galls offer protection from wasps but larger galls are preyed upon by woodpeckers for the larvae within. The researchers鈥 goal is to shed light on the natural selection forces that favour a gall that is neither too small nor too large 鈥 and the genes that may be the basis for determining size.</p> <p>The students began by finding goldenrod plants with galls. Their next step was to protect the fly larvae from wasps by wrapping the galls in mesh. Over the summer, Peters and Wagner 鈥渂agged鈥 over 700 galls.</p> <p>The students then collected galls and sorted them by size.</p> <p>&nbsp;</p> <p><img alt src="/sites/default/files/peters-609-crop.jpg" style="width: 750px; height: 500px;"></p> <p><em>The students collected goldenrod flies that have emerged from galls&nbsp;(photo by Kemeisha McDonald)</em></p> <p>鈥淣ext, we鈥檒l sequence all the flies to figure out whether all the big-gall flies have a similar section of their genome,鈥 says Wagner. 鈥淭hen, we鈥檒l look to see if some of the genes in this section play a role in causing a specific size of gall.鈥</p> <p>For Weis, the program&nbsp;is rewarding as both an instructor and a scientist.</p> <p>鈥淭his is what it's all about 鈥 working with students in the lab or in the field,鈥 he says. 鈥淪tudents who are curious, enthusiastic and want to learn. And in the process, it extends my own research and helps me answer the questions I'm curious about.鈥</p> <p>For Wagner and Peters, the experience has provided them with much more than an opportunity to do research.</p> <p>鈥淚t鈥檚 really added context for me for when I鈥檓 reading a research paper,鈥 says Wagner. 鈥淏ecause now, I've experienced the entire research process, hands-on.鈥</p> <p>Peters, meanwhile, says she鈥檚 planning to pursue a PhD,&nbsp;鈥渟o, it's been cool seeing and talking with other researchers up here and learning about what they're doing for their masters and PhDs.</p> <p>鈥淎nd working outside in the field all day has been amazing. I鈥檝e seen so many things 鈥 like my first porcupine! It鈥檚 been a really great experience that鈥檚 shown me how amazing field work is. It鈥檚 really solidified in my mind that this is what I want to do for the rest of my life.鈥</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 14 Sep 2022 13:22:07 +0000 Christopher.Sorensen 176556 at John M.
