Third-year marine sciences major Ian Jones of Canton, Conn., is studying how ocean acidification impacts lobster larvae, an important resource for the Maine economy.
Jones works with American lobsters raised at UMaine’s Aquaculture Research Center (ARC). The lobster larvae were raised last summer at various pH levels, replicating natural environments and the impact of ocean acidification. Jones weighed and photographed approximately 700 lobster larvae to monitor their growth in these different environments. The hypothesis: slower growth and more irregular development occur at lower pH. This creates adaptation problems for lobsters dealing with increased environmental CO2 levels.
“We will certainly see greater ocean acidification in the future as an effect of climate change. As atmospheric levels of CO2 continue to increase from human input, so do the CO2 levels of the upper ocean,” says Jones.
Along with lobster larvae, Jones also monitored seahorses in Tim Bowden’s lab. The seahorses, which were dealing with a mycobacterial infection, were in the care of Jones while an antibiotic treatment was created. He also raised juvenile seahorses last year. Through this experience, Jones learned about seahorse aquaculture, proper feeding protocols, tank chemistry and more.
“Not much is known about seahorse aquaculture relative to raising other fish, so although information on raising newborns was limited, it was a fun challenge figuring out our own system that worked.”
This fall, Jones will travel to the Darling Marine Center on the Damariscotta River, where he and other UMaine students will further the hands-on work they do in the classroom through the Semester By the Sea program.
Jones plans to attend graduate school to study sensory biology and/or the effect of climate change on marine animals.
Why is your lobster research important?
Research on American lobster growth at lowered pH is incredibly important first, because there has been little climate change study on this particular species and second, any slowing or other adverse effects on lobster growth could have serious impacts on the health of the lobster fishery, which Maine, of course, greatly depends on. Delayed lobster larvae development means it will take longer for lobsters to get to market size, and predation risk may increase as well, causing fewer individuals to grow into adults and lowering the overall abundance of adult lobsters. Changes in lobster abundance can in turn upset ecosystem balance by changing the abundance of organisms that depend on lobster as prey and organisms lobsters prey on. These trophic cascades have the power to reduce the presence of many species in addition to just the lobster, consequently reducing biodiversity.
Are you excited about heading to the Darling Marine Center in the fall?
I am really excited to be able to SCUBA dive in the area on the weekends; there is a dive locker on campus. I’m also excited for many of the courses offered this fall, such as the scientific diving course and the marine invertebrate biology course. I look forward to the seminar class, which teaches students how to tackle job interviews and graduate school applications for pursuing a career post graduation. Generally, I look forward to interacting with the marine environment on a near daily basis as I learn more about it and gain skills for marine research.
Why did you choose UMaine?
My primary reason for choosing UMaine was their excellent marine science program, which was more attractive than those at other colleges due to its emphasis on hands-on experience, such as through their Semester by the Sea program, expert faculty and it covers fundamentals of marine biology, chemistry and physics, not just the area you choose to concentrate in. Also driving me to UMaine were the strong nondiscriminatory policies and minority services on campus, making me confident that I can be myself at UMaine and face minimal to no prejudice, especially from faculty and administrators.
Have you worked closely with a mentor, professor or role model who has made your UMaine experience better, if so how?
Working with Tim Bowden has greatly improved my experience here, and the opportunities he’s granted me to assist with seahorse aquaculture and lobster larvae research have not only been very enjoyable but have helped define my research interests and add to my qualifications for future research experience. Additionally, his constructive feedback on my performance in his lab has allowed me to improve as a researcher.
What difference has UMaine made in your life, helping you reach your goals?
My professors at UMaine have made a major impact on what it means to have a career in science and beyond. They share advice on the mentality, skills and process necessary toward being successful in particular research fields. Also, the abundance of research facilities here, such as the Aquaculture Research Center, has allowed me to build a lot of hands-on experience that I can apply to future positions in marine biological research.
What advice do you have for incoming students?
I advise students to get involved with at least a couple student organizations that suit their interests. There’s a club for almost anything you could think of, from fencing to SCUBA diving to various political, academic and religious and social groups. Also I recommend science students look for work in a faculty member’s lab as soon as possible, even if it’s just volunteer work. You don’t need to know what your interests are yet, but any research and lab experience gained early can really help you in the long run. Just ask around.
What is your favorite place on campus?
My favorite place is the Littlefield Garden on the north end of campus. The garden is especially nice to study in, or to just hang out and have a picnic at — given warm weather of course.
Have you had an experience at UMaine that has shaped the way you see the world?
Unrelated to marine science, I took the Intro to LGBT studies course offered by the Women’s, Sexuality and Gender Studies department, which vastly increased my understanding of the complexity of the LGBT community. I knew a fair amount about LGBT culture and identities going into the course but I did not realize how much I didn’t know until taking the class. For example, I didn’t know that there is opposition to same-sex marriage within members of the LGBT community and that historically there has been plenty of conflict of interest between feminist and lesbian organizations, as well as lesbian and gay people who have spearheaded “LGBT” movements that often leave the B (bisexual) and T (transgender) out of the equation. I now view the LGBT community differently than before, recognizing that people won’t always get along or share common goals just because they all belong to a minority. I also better understand the importance of full inclusiveness in LGBT organizations, due the diversity and intersectionalities with race, class, etc., of LGBT people.
