Amy Marcarelli: Distinguished Teaching & MASU Distinguished Professor of the Year Nominee

Amy Marcarelli
Amy Marcarelli

Congratulations to Amy Marcarelli! She is one of the 2023 Distinguished Teaching Award winners. She also is a nominee for the 2023 University’s MASU Distinguished Professor of the Year.

Amy is an ecosystem ecologist with interests in energy and biogeochemical cycles in freshwaters. Her research program blends basic and applied research and integrates across aquatic habitats, including stream, river, wetland, lake littoral zones, and the nearshore regions of the Great Lakes. Marcarelli’s past and future research trajectory is governed by an interest in understanding the role of small, poorly quantified fluxes or perturbations on ecosystem processes and in linking those ecosystem processes to the underlying structure of microbial, algal, macrophyte and animal communities.

Since 1982, a Michigan Tech Distinguished Teaching Award has been presented annually in each of two categories: Associate Professor/Professor and Assistant Teaching Professor/Associate Teaching Professor/Teaching Professor/Professor of Practice/Assistant Professor. The award nomination and review processes have always been student-driven; an explicit student nomination process was discontinued in 1999 when it was determined that too few students were participating to identify the best candidates.

Since 1999, a group of five finalists in each of the two categories is selected based on student ratings of instruction completed during a calendar year. All instructional personnel who received at least 35 student ratings during spring and fall semesters within that calendar year are eligible except for those who are previous winners, department chairs, teaching assistants, temporary hires, etc. Eligible faculty are ranked by their cumulative average of the 7-Dimensions on the survey for the given year. The top 5 in each category are selected as finalists.

The Michigan Distinguished Professor of the Year award recognizes the outstanding contributions and dedication exhibited by the faculty from Michigan’s 15 public universities to the education of undergraduate students. Each university was invited to nominate a faculty member who has had a significant impact on undergraduate student learning through various activities, particularly classroom instruction, applied research, experiential learning, innovation and mentoring.

Nursing Nuggets: Allison’s Advice for Nursing Newbies

Clinicals are a key component of any nursing program. students will spend as much as 180 hours in a healthcare setting like a hospital, urgent care, or long-term care facility, getting hands-on experience. We spoke with Allison Cooper, who talked about her clinical experience. She also discussed the benefits of academic families, a key way incoming nursing students are supported by their peers. Allison also offers advice to students interested in pursuing this degree.

Allison Cooper

Why did you choose to go into nursing? Was there a life experience you had?

My mother was a nurse before she got chronically sick with Chronic Fatigue Syndrome (CFS) when I was about two years old. Originally I thought I wanted to go into nursing because of her being a nurse. However, that was not the case. What drew me to nursing was my love for science but with a human twist. I remember always looking up CFS to learn more about something that still does not have a cure. I also was able to watch my own surgery and thought that it was the coolest thing ever to see my tendons and how they move.

I also love the direct patient contact nursing has to offer. Nurses are one of the biggest support persons for patients who are, sometimes, at the lowest part of their lives because of being sick. For me specifically, I wanted to be able to give back to the men and women in the military and work as a nurse within the military.

The concept of an academic family enhances the learning experience. How did your academic family help you in your first years in the program?

The first year of the nursing program can be difficult because of learning how to balance school, work, and social life. My academic family was not only a mentor but a massive support system when figuring this out. I was able to go to them with any questions I had about classes and how to time manage everything. They were also my family away from home, and I was able to do non-nursing activities and build lasting friendships with them!

In what way did the academic family concept help you as an upperclassman mentoring newer students?

I loved the academic family even more as an upperclassman. I actually found a passion for teaching, which is something I never saw myself doing. It was a great way to ease the sophomores’ nerves as they went through their first year in the program. It was also a great refresher for information as I began studying for the NCLEX!

Where did you complete the majority of your clinical hours?

We completed the majority of the clinical hours at the local hospitals- Portage and Aspirus. But, we had a lot of different experiences. We went to the local clinics. We went to Marquette for more specialty areas, such as psychiatric and neonatal intensive care nursing.

I had the opportunity to visit many settings. The majority of it was in the hospital setting between medical-surgical, emergency room, intensive care unit, surgery, and labor and delivery. But, I was able to go to Marquette for more critical care in their intensive care and emergency room. I also did a couple semesters with rotations in hospice, oncology, pediatrics clinic, and pediatric cardiology, and family practice clinics!

My favorite clinical experience was in the emergency room in Marquette. I was able to see a trauma in the ER which I always thought would be a setting I’d like. So, it was great to be able to be in the midst of it helping. It definitely solidified that as an area I could see myself in! I also really enjoyed labor and delivery because it was something that I didn’t think I’d have an interest in. But, with that rotation, I was able to see and do the nursing care for deliveries of newborns. That was when I realized that I also enjoyed that area of nursing as well.

What are some of the things you did during nursing clinicals? What did you enjoy the most about the experience?

Throughout my three years of clinical experience, I was able to practice many nursing skills, like IV inserts, inserting Foley catheters, and suctioning! I feel going through the clinical rotations, a student learns the fundamentals of nursing and how to be a nurse. I learned how to effectively communicate with patients therapeutically and how to put into practice the concepts we learned in the classroom. What I enjoyed the most about my clinical experience was being able to physically be in the different specialties. This helped me narrow down the things that I liked and did not like. I also really enjoyed being able to practice my skills in a real-life setting.

What did you learn about yourself from the clinical experience?

The clinical experience allowed my passion for nursing and compassion for people to really shine through. It made me realize nursing was the best choice I could have chosen for myself! In addition, I learned that I am able to persevere through challenges and problem-solve.

How do you think the clinical experience has set you up for success in your after-graduation plans?

The program has us go through a detailed clinical. We spent 180 hours a semester at sites and had paperwork to fill out for the rotations. I feel this prepared me very well for life after graduation because of all the in-person time I had in a setting where I would be working while practicing my skills. The paperwork, although sometimes tedious, was well worth it. As I filled it out, it made me think about diseases and how it affects a person. It made me feel comfortable and confident going into my career.

What advice do you have for students getting ready to go through clinical?

The biggest advice I have for students going through clinicals is to always ask questions and get involved in as much as possible. This is the only way you will get the most out of your experience and benefit your education. It was what I did, and I felt I got more out of the clinicals, enhanced my knowledge bank, and practiced skills I know I will need when I graduate.

Allison, what advice do you have for high schoolers who are considering getting a bachelor’s of science in nursing?

Deciding whether or not you want to pursue a BSN can be difficult. I feel shadowing nurses or becoming a certified nursing assistant can really help you decide if it would be a good fit. I did both of these, and it really showed me that I had a passion for nursing and solidified my choice. If that isn’t a doable option if you really enjoy science and anatomy and physiology, this could be a great fit, and I would suggest you give it a try! A BSN also gives you many leadership experiences! It allows you to go into management and other avenues that nursing has to offer other than bedside in hospitals!

NOTE: Allison Cooper received her BSN from Finlandia University in May of 2023. Finlandia University closed in June 2023. The Nursing program (including most faculty and staff) moved to Michigan Technological University shortly thereafter. Tech will incorporate many of the same components Allison mentions in the interview, including clinicals, academic families, coursework, and NCLEX prep. As of the date of this post, the Bachelor of Science in Nursing (BSN) degree is in the process of obtaining accreditation by the Commission on Collegiate Nursing Education (CCNE) and The Higher Learning Commission (HLC). The program has been approved by the Michigan State Board of Nursing. Check back this fall for more detailed information on this exciting new program coming to Michigan Tech.

1. Exciting findings that genome size can affect resource requirements and genomic/transcriptomic functional trait trade-offs. 

Abstract

Premise: Increased genome-material costs of N and P atoms inherent to organisms with larger genomes have been proposed to limit growth under nutrient scarcities and to promote growth under nutrient enrichments. Such responsiveness may reflect a nutrient-dependent diploid versus polyploid advantage that could have vast ecological and evolutionary implications, but direct evidence that material costs increase with ploidy level and/or influence cytotype-dependent growth, metabolic, and/or resource-use trade-offs is limited.

Methods: We grew diploid, autotetraploid, and autohexaploid Solidago gigantea plants with one of four ambient or enriched N:P ratios and measured traits related to material costs, primary and secondary metabolism, and resource-use.

Results: Relative to diploids, polyploids invested more N and P into cells, and tetraploids grew more with N enrichments, suggesting that material costs increase with ploidy level. Polyploids also generally exhibited strategies that could minimize material-cost constraints over both long (reduced monoploid genome size) and short (more extreme transcriptome downsizing, reduced photosynthesis rates and terpene concentrations, enhanced N-use efficiencies) evolutionary time periods. Furthermore, polyploids had lower transpiration rates but higher water-use efficiencies than diploids, both of which were more pronounced under nutrient-limiting conditions.

Conclusions: N and P material costs increase with ploidy level, but material-cost constraints might be lessened by resource allocation/investment mechanisms that can also alter ecological dynamics and selection. Our results enhance mechanistic understanding of how global increases in nutrients might provide a release from material-cost constraints in polyploids that could impact ploidy (or genome-size)-specific performances, cytogeographic patterning, and multispecies community structuring.

2. Finding that tetraploid Giant Goldenrods may be pre-adapted to be good invaders but that polyploidy per se does not increase phenotypic plasticity. 

Abstract

Polyploidy commonly occurs in invasive species, and phenotypic plasticity (PP, the ability to alter one’s phenotype in different environments) is predicted to be enhanced in polyploids and to contribute to their invasive success. However, empirical support that increased PP is frequent in polyploids and/or confers invasive success is limited. Here, we investigated if polyploids are more pre-adapted to become invasive than diploids via the scaling of trait values and PP with ploidy level, and if post-introduction selection has led to a divergence in trait values and PP responses between native- and non-native cytotypes. We grew diploid, tetraploid (from both native North American and non-native European ranges), and hexaploid Solidago gigantea in pots outside with low, medium, and high soil nitrogen and phosphorus (NP) amendments, and measured traits related to growth, asexual reproduction, physiology, and insects/pathogen resistance. Overall, we found little evidence to suggest that polyploidy and post-introduction selection shaped mean trait and PP responses. When we compared diploids to tetraploids (as their introduction into Europe was more likely than hexaploids) we found that tetraploids had greater pathogen resistance, photosynthetic capacities, and water-use efficiencies and generally performed better under NP enrichments. Furthermore, tetraploids invested more into roots than shoots in low NP and more into shoots than roots in high NP, and this resource strategy is beneficial under variable NP conditions. Lastly, native tetraploids exhibited greater plasticity in biomass accumulation, clonal-ramet production, and water-use efficiency. Cumulatively, tetraploid S. gigantea possesses traits that might have predisposed and enabled them to become successful invaders. Our findings highlight that trait expression and invasive species dynamics are nuanced, while also providing insight into the invasion success and cyto-geographic patterning of S. gigantea that can be broadly applied to other invasive species with polyploid complexes.
