Jill Olin was co-author of a paper that recently appeared in the Journal of Fish Biology. The co-authors argue that research about sharks and their populations needs to be expanded in the face of recent spikes in shark-human interactions in the coastal areas of New York. In addition, ECO Magazine recently mentioned the paper in a story about shark attacks along the New York coast.

O-fish-ally Fin-tastic Research!

Tessa Tormoen is a fourth-year student majoring in ecology and evolutionary biology with a minor in fish biology. She is one of the most adventurous people you’ll ever meet. You can often find her cross-country skiing on the Swedetown and Tech Trails. Not only is she a fan of heart-racing adventures, but her curiosity has also led to her getting involved in undergraduate research. Throughout Tessa’s classes, she learned the basic skills and processes needed in the lab. Her confidence grew. She was ready to put these skills into practice and take on an independent project. In the fall of 2021, she discussed her interest with Dr. Kristin Brzeski, assistant professor at Michigan Tech.

Fishing for DNA

Dr. Brzeski put Tessa to work observing Golden and Blueline Tilefish. She extracted DNA from the digestive tracts of predator fish and constructed what the taxonomic group looks like by using a method called Metabarcoding, which is a process of DNA sequencing and identification. Using this technique she was able to characterize the dietary composition of the two different tilefish species to better determine the species’ niche breadth (or use of food resources in this case) and degree of similarity. This is one factor showing how the two species co-exist.

Like any craft, it’s a continual learning process. Working alongside graduate students and mentors, she developed her independent problem-solving and management technique. Learning the ins and outs of research was a steep learning curve, but Tessa was able to gain valuable skills and knowledge during her time as a researcher. “It’s a joy to have an undergraduate like Tessa in the lab. She brings passion, intelligence, and a genuine interest in research and natural resource conservation to every interaction,” said Dr. Brzeski.

Tessa exhibited her research at the 2023 Undergraduate Research Symposium, winning the third place GLRC award. She also won a merit award at the Ecosystem Science Center poster session. And she presented her findings at the Wildlife Society National Conference in Spokane, Washington with others in her lab.

A Close-Net-Bunch

Tessa believes that her experiences in research have helped shape the future for the better. “I’m a lucky person. I’ve had an incredible four years. Jill Olin and Kristin Brzeski [have] built me into an independent scientist. They taught me how to solve problems, how to be independent and confident in my abilities,” she says. She credits both graduate and undergraduate colleagues in the lab with perpetuating the culture Drs Brzeski and Olin cultivated. “It was a welcoming and hopeful atmosphere.”

That feeling extends to the department. “Everyone is extremely kind, no matter who you talk to! All of my professors throughout my coursework have been very approachable and extremely passionate about what they study. I love that the biological sciences department is so personal and you can build relationships with the faculty. It truly makes the department’s environment so incredible. The support I have received from my advisor and my professors has been a valuable part of my education. I also love how the biological sciences department is a bit smaller compared to other departments like engineering. Each semester I recognize many familiar faces. I’ve been able to create great relationships with my peers through this,” Tessa said.

The Water is Just Right at Michigan Tech

Like many before her, Tessa chose to study ecology and evolutionary biology at Michigan Tech because she fell in love with this area. “I realized that I have a passion for understanding the world around me and this is a beautiful place to do that,” she said. “Plus, the experiences you’re able to have in this degree are fantastic, and I was compelled by the sheer amount of opportunities available to me.”

Tessa appreciated the flexibility the ecology and evolutionary biology degree program offered. “A lot of the coursework is electives that you get to choose from, so you can tailor your education to what you are most interested in. Thus, I was able to take courses like Mammalogy, Tropical Island Biology, Valuing the Great Lakes, Botany, and more!” Tessa said. “Sometimes you get to go outside for classes; one of my biggest memories from my degree is my Tropical Island Biology course, where we stayed in the Bahamas over Spring Break. This degree program has given me such a strong foundation and a whole list of interests that I can build upon with secondary education and post-education work experience.”

In addition to research and the degree program, Tessa took advantage of other opportunities on campus. She served as vice president of the Ski and Snowboard Club. Tessa also coordinated activities as part of the Women’s Leadership Council.

Leaving the School: Tessa’s Post-Graduation Plan

Following commencement this month, Tessa plans to “go with the flow.” This summer, you’ll find her on Isle Royale working as a fisheries technician, performing limnological assessments and fish surveys on their inland lakes. “I’m excited about this opportunity as it honestly feels like a dream job,” she said.

After taking one year to work in the field and gain more experience, Tessa wants to return to school for her master’s degree and potentially a Ph.D. “I think my experience at Michigan Tech has helped me greatly in understanding the opportunities available to me after graduation. I think that my education, research experience, and relationships at Tech have set me up for success once I leave,” she said.

We are certain her future will go swimmingly well!

Congratulations to Jill Olin and her postdoctoral fellow, Jim Junker, who recently published a paper titled “Can biodiversity of preexisting and created salt marshes match across scales? An assessment from microbes to predators” in the Ecosphere Journal. You can learn more about the research on the LSU website.

Abstract: Coastal wetlands are rapidly disappearing worldwide due to a variety of processes, including climate change and flood control. The rate of loss in the Mississippi River Delta is among the highest in the world and billions of dollars have been allocated to build and restore coastal wetlands. A key question guiding assessment is whether created coastal salt marshes have similar biodiversity to preexisting, reference marshes. However, the numerous biodiversity metrics used to make these determinations are typically scale dependent and often conflicting. Here, we applied ecological theory to compare the diversity of different assemblages (surface and below-surface soil microbes, plants, macroinfauna, spiders, and on-marsh and off-marsh nekton) between two created marshes (4–6 years old) and four reference marshes. We also quantified the scale-dependent effects of species abundance distribution, aggregation, and density on richness differences and explored differences in species composition. Total, between-sample, and within-sample diversity (γ, β, and α, respectively) were not consistently lower at created marshes. Richness decomposition varied greatly among assemblages and marshes (e.g., soil microbes showed high equitability and α diversity, but plant diversity was restricted to a few dominant species with high aggregation). However, species abundance distribution, aggregation, and density patterns were not directly associated with differences between created and reference marshes. One exception was considerably lower density for macroinfauna at one of the created marshes, which was drier because of being at a higher elevation and having coarser substrate compared with the other marshes. The community compositions of created marshes were more dissimilar than reference marshes for microbe and macroinfauna assemblages. However, differences were small, particularly for microbes. Together, our results suggest generally similar taxonomic diversity and composition between created and reference marshes. This provides support for the creation of marsh habitat as tools for the maintenance and restoration of coastal biodiversity. However, caution is needed when creating marshes because specific building and restoration plans may lead to different colonization patterns.
