SEA Semester, a new way for college students to do field research

Erika Reiter, TriBeta PR
Humans have challenged the limits of human ingenuity by landing a man on the moon. At the same time, marine scientists have plummeted into the depths of our own oceans to unlock its evasive secrets.
The study of the oceans has become an increasingly interdisciplinary subject because researchers are realizing that it plays such a crucial part in the development of the world’s history, economy, and culture. Following this trend, a new field experience is available to undergraduate students who are interested in learning more about our oceans. 
Sea Education Association (SEA) is offering students around the world a chance to participate in their hands-on research program to broaden society’s understanding of the world’s oceans. It’s aptly named “SEA Semester” because participants spend several months involved in studying in the program while at sea. According to their website, SEA is the “only educational organization with custom-built sailing vessels” and SEA Semester has two ships that are each 134 feet long.
SEA Semester’s ports-of-call in the past have included Hawaii, Nova Scotia, Trinidad and Tobago, Palmyra Atoll and several others in the Caribbean. This year, one of their destinations includes the Polynesian Islands.
The courses offered incorporate studies of ocean exploration, resource conservation, culture of the Caribbean, world climatology, sustainability, biodiversity and energy production. The topics are approached from many different perspectives, including the social sciences, natural sciences, public policy and technology. Students take with them skills learned from working together with a team of other students to develop their own research projects in the onshore components of the program. The rest of their time is spent on the open oceans and 12-18 college credits are awarded for the completion of the program. Students on board become immersed in sea-faring life and are involved in all activities on the ship, not just in their research. 
Sea Education Association has sailed over one million nautical miles and has taught over 7,500 students in the past 40 years.

Adam Urbanski's “Glimpses into FSC Biology Research”

Adam Urbanski, TriBeta Vice President
                FSC biology students are participating in many exciting research projects this semester as members of the Ecology Research or Molecular Biology Research courses.  Their projects investigate a wide variety of biological questions and seek to create new knowledge and increase information about their topics.  Below is a glimpse into some of the ongoing research in the Molecular Biology course. 
                Seniors Jordan Campbell, Han Nguyen, and Jon Scott are investigating the DNA of the elusive Siren lacertina, a large aquatic member of the salamander family that can be found in Lake Hollingsworth.  The team is working with members of the Ecology course to capture and tag specimens in the lake and acquire DNA samples from them.  Once the molecular biology team has isolated and amplified the DNA, they will use several DNA primers to sequence a portion of the genome.  This information will be used to compare and analyze differences in DNA sequence to related salamander species Pseudobranchus.
                Jessie Fleming and Alexander Stein (also seniors), are working with Raphanus sativus:  the radish.  They will be studying radish seeds that have been exposed to specific amounts of radiation and quantifying the amount of genetic damage that is suffered from different amounts of radiation exposure.  The team plans to grow the irradiated seeds for several weeks and gather enough plant material to extract DNA from each exposure level.  The DNA will be analyzed and compared using Southern Blotting and Gel Electrophoresis techniques.  Fleming and Stein hope to use their data to predict damage done to flora exposed to radiation from the Fukushima Daiichi nuclear plant in Japan.
                Finally, seniors Byron Hu, Sebastien Parisot, and Adam Urbanski are exploring the photoreactivation mechanism of DNA repair.  Photoreactivation mends UV damaged genetic material through exposure to visible light.  The team plans on isolating the genes necessary for light production in bioluminescent bacteria and transferring them into strains of Escherichia coli (bacteria) and Saccharomyces cerevisiae (yeast) so that they will also exhibit bioluminescence.  These “glow in the dark” strains will be exposed to UV radiation and placed in dark surroundings.  The team will measure the transformed strains capability to heal their DNA through photoreactivation stimulated by their own light production.  

TriBeta President, Byron Hu, interviews Dr. Macedonia


Bryon: Where are you from originally?

Macedonia: I come from a small town in central Pennsylvania.  I found the landscape and town boring growing up, and had a desire to see and live in the western USA where the landscapes are more dramatic.   So I did that – I’ve lived in Colorado, Arizona, and California, among other places.

Byron: What classes are you teaching in the spring?

Joseph MacedoniaMacedonia: In the Spring I teach Zoology, all the lecture sections and three of the labs. I also teach a study abroad course in even years on the behavioral ecology of Anolis lizards. I only take 10 students, most of whom I invite because I’ve gotten to know them in another course that I’ve taught. I do this together with a colleague at a small college in central Michigan, so we have a total of 20 students.  Some years we go to Bermuda, like this coming May; other years we go to Jamaica.  We’re branching out, however, and we plan to do a trip to the Galapagos Islands in May 2014.  Lizards,of course.

Byron: I have read that your interests include animal signals and coloration, what do you think is the coolest example of this?

Macedonia: That’s an impossibly difficult question to answer, really, because there are too many great examples. I would probably say, an animal that can change their coloration between being inconspicuous and highly conspicuous.  Although Anolis lizards do this by extending their colorful dewlap (throat fan), and true chameleons can change their body coloration very rapidly due to innervation of the pigment cells, no animals are as accomplished at changing color patterns as cephalopods – octopus and squid family.  The cuttlefish is perhaps the most spectacular, blending in with the background one minute, sporting a black-and-white striped pattern the next that looks exactly like a zebra, and doing the “moving cloud”, flashing pattern of light across the body.

Byron: If you could be any of the animals that you have researched and published papers on, which would you be and why?

Macedonia: I suppose it would be a lemur, one of the species call “sifakas” that are leaping specialists.  I particularly like Coquerel’s sifaka.  But I have much more in common with cats than any animal I’ve studied.  Like cats, I’m aloof, am naturally nocturnal, I’m a carnivore, I can be gregarious but I tend toward being solitary…. If I were a non-primate, I am best suited to be a cat.

Byron: Which animal has the strangest mating behavior?

Macedonia: Hmmm… animals with sexual suicide, like some spiders where the male becomes a meal for the female after mating, is pretty out there.  But it all makes sense in terms of natural selection.  When the odds of getting a mate is low, and the extra nutrition provided by the male body allow females to make and fertilize more eggs with that male’s sperm, sexual suicide is in the male’s best interest: it increases his reproductive success.

Byron: Do you have any pets?

Macedonia: A cat, of course.  I only have one at present, because he isn’t big on sharing me with others.  I’ve had him for 13 years.  I’ve had multiple cats before, and I will again.

Byron: Could you give us aspiring researchers some advice for the future?

Macedonia: Get experience as early in your academic career as you can.  For example, I was doing independent study research projects as a freshman.  All Biology majors are now required to take two semesters of research, which gives you an edge at getting into professional schools and graduate schools.  But you have to have the right temperament for serious research.  Self motivation, goal orientation, being content with delayed gratification… all of these are required to be a researcher.  Most of all, I think, you have to have a passion for research.  If you don’t have a strong desire to discover the answer to a question, or at least a passion for working with a particular type of organism, the delayed gratification and frequent failures in research will probably be too frustrating for you in the long run.

Byron: I’m told you are a big caffeine junkie. What are your thoughts on the subject?

Macedonia: I no longer drink coffee as too much upsets my stomach.  So I drink a lot of Red Bull and Water Joe to get through the day. I tend to burn the candle at both ends during the regular semester… getting more than five hours of sleep on week nights is rare. I’ve been a night owl since I was an adolescent.  I have something termed DSPS, which is Delayed Sleep Phase Syndrome. The condition has been linked to being homozygous at certain loci in genes that control your circadian rhythm – your body clock.  Everyone has times of day when they are mentally at peak performance, and other times when they are at a low point.  I’m the opposite of a morning person because my body clock runs differently than it does for most people.  My father worked the graveyard shift in a hospital for 23 years, so “nocturnality” runs in the family, so to speak. I naturally begin to become very alert about 11 pm, and, if left to my own devices, I’m at peak mental performance between 1 am and 4 am. This is true if I sleep 8 hours, 4 hours, or 2 hours – I still wake up at that time of night.  It’s a bit of a crutch given that most humans are diurnal.

TriBeta President, Byron Hu, interviews Dr. Langford


Byron: Where are you from?
Langford: I consider my hometown to be Lawrence, Kansas.

Picture
Byron: So you are a big Kansas Jayhawk?
Langford: Yes. Although I spent time in Huskerland, it was hard to switch teams. I think most of the Huskers are a little crazy. The entire state is obsessed with one team. There are no pro sports, and there is only big university. Huskers who leave Nebraska are usually told, "You are a little too excited about Husker football."


Byron: What inspired you to study zoology?
Langford: I grew-up catching frogs, toads, lizards, and snakes in Kansas, and I suppose I've never stopped. I love it. I first realized I wanted to catch critters for a living after watching and working with the greatest snake biologist of all time Henry Fitch during my undergraduate at the University of Kansas. He was an amazing naturalist!


Byron: What is one piece of advice for future researchers?
Langford: Keep your eyes open! In other words, always be making observations, you never know what you might discover, especially when you are out in nature.


Byron: Do you have any pets?
Langford: 2 dogs, a Border Collie and a Collie/Australian shepherd mix; I frequently walk them on campus. I used to have 2 large Carpet pythons, but I gave them to a friend before my daughter was born.

Byron: Who is your hero of zoology?
Langford: I don't know if I have a hero, but I have been greatly influenced by Henry Fitch, Val Smith, David Nelson, and John Janovy, Jr.


Byron: What are your hobbies?
Langford: I enjoy backpacking, exploring, and playing basketball. We are going camping somewhere around Lakeland for the first time this winter. While I was in Nebraska or Kansas, we’d go camping in Colorado a lot. I’d drag my wife up and down several large mountains. We climbed the highest peak in Colorado, Mount Elbert; it’s over 14,000 feet high. We brought our dogs with us.


Byron: Please tell us an embarassing story about yourself.
Langford: I don’t find this embarrassing, but I think my wife was embarrassed by it. This happened in 2006 while I was doing my doctorate studies. While vacationing in Azul Mijares, a little island off Cancun, Mexico, I saw packs of dogs at night all over the island. They were likely infected by a intestinal parasite known as Ancylostoma, sometimes called a hookworm. It does not normally infect people, but it can penetrate human skin and gets lost because it does not recognize its host.
(Please do not attempt this at home)

Basically, I let one of these hookworms infect my toe and kept it alive by not squishing it so that I could observe it moving underneath the skin. I guessed it would live about 10 days before my immune system would naturally kill it, so I was hoping to get a photo of it at the end. One night we were taking in some margaritas and I tripped, stubbed my toe, and killed the hookworm early.

But I did have this nice path on my toe, and I show a Powerpoint picture of where it went. (Dr. Langford is teaching Parasitology next Spring) I thought it was kind of cool as a parasitologist, but my wife was really embarrassed by it.

Jen Bruno, a recent graduate from FSC, speaks about Medical School


What has inspired you to get this far?
 "As I’ve heard numerous times from my lecturers in med school, becoming a doctor is a marathon, not a sprint. In order to commit to a twelve year-plus training program (four years of undergrad, four years of medical school, and four or more years of residency) this has to be something that you really want. The quality I would deem most important in getting me to this point is a true love of learning. 

I am drawn to the medical profession because of the direct impact it will allow me to have on patients' lives, but the first years of training are very much centered on rigorous classroom learning. With the end goal still years down the line, it is easier to stay motivated if you love the science.  I was lucky to have professors in undergrad (as well as here at USF COM) who made me excited about what I was learning. 

This is so important because even after earning a medical degree, great doctors are always students. In this profession you’re never finished learning new things; there will always be new procedures to master, new drugs to prescribe, and more journals to read. With the ultimate goal of providing exceptional patient care in mind, the key for me is to appreciate that I can never know everything, but to harness the drive to always learn more."

How does it feel at this point?
"Really exciting!  Right now I have so many opportunities available to me, and I’m immersed in a culture that is structured around helping me to become the best physician possible.  Medical school is overwhelming at times, but it’s also an environment where everyone wants you to succeed and reach your full potential because in four years you’ll be responsible for people’s lives. It’s also really awesome to be surrounded by 150 other highly motivated students that share the same interests."

How did your first block go?
"USF, like many medical schools across the country, has a curriculum structured around Systems Based Learning. This means that instead of studying anatomy, physiology, genetics, biochemistry, etc. separately, for each block we focus on a specific system of the body (this block was musculoskeletal) and learn all of the subjects as they apply to that system in an integrated fashion. It was definitely an adjustment figuring out how to effectively study for information covered in this manner, just because it’s such a different way of learning than in undergrad.

Overall, this block was really about getting used to managing my time differently, meeting my new class, and becoming acclimated to a different learning environment."

 What did FSC prepare you for?
"The foundation of knowledge I gained at FSC has made me as prepared, and in some cases more prepared, than my classmates for taking an in-depth look at the basic sciences, which is the major premise of the first year of medical school. I am finding that I have at least been exposed to most of the lecture material that we’ve covered so far. There have been many times over the past couple of months that I’ve been extremely grateful to have learned as much as I did in undergrad in biochem, genetics, and cell biology. The fact that professors at FSC challenged me during their classes has made my life so much easier now!"

What didn’t FSC prepare you for?
"I wouldn’t say (at least at this point, but it’s still really early) that medical school is intellectually any more difficult than undergrad. The difference is the sheer magnitude of information that is thrown at you week after week. I don’t think that it’s possible to be prepared for covering so much material in such a short amount of time until you actually experience it. This isn’t a fault of FSC, it’s just a reality of medical school."

 What will you be up to in the months to come?
"The next few months will be particularly exciting because we are beginning our first official clinical assignment, where for a half day each week we will get hands on experience with patients. USF has a really unique program that allows students to choose a Scholarly Concentration, which is sort of like a minor. 

I’m doing mine in Business and Entrepreneurship, and in the coming months I hope to participate in some research looking at efficiency, allocation of resources, and treatment outcomes in the student-run clinic at USF. Other than that I’ll be continuing to learn anatomy in cadaver lab and completing Block 2, which is neurology."

Do you have any suggestions for pre-meds at FSC?
"I would highly suggest that anyone planning on going to medical school take cell biology, both biochemistry 1 and 2, and genetics, even if they are not required for your major. These classes cover a lot of information that you WILL see in your first year of medical school, and you’ll be at an advantage if you’ve already been exposed to it. 

While anatomy is largely memorization, I have found it to be very time consuming, which means that it detracts from the time you have to study the massive amount of lecture material you will encounter. Surprisingly, many of my classmates never took an anatomy class in undergrad. DEFINITELY take anatomy at FSC, and take the time to learn the structures now. It will make your life so much easier later. I also highly recommend Dr. Lynch’s medical terminology class because there isn’t enough time for our lecturers to stop and teach us the meaning of every term they use. You’re just expected to know the terminology, or else learn it on your own very quickly.

Second, I would say to remember that not everyone takes the traditional route into medical school. Many of my classmates took a year or more off to do research, work in another career, improve their MCAT score, or join the Peace Corps before starting medical school. While I knew that keeping the momentum going was best for me, it works best for a lot of other people to have some other experience first.

Lastly, this probably goes without saying, but make sure that you really want to make this commitment. There are far easier ways to make money and gain prestige, but I can’t imagine enjoying medical school if my heart wasn’t in it. It’s not a cake walk, but if you really want to become a doctor medical school is a lot of fun and really rewarding."

Keri McClure speaks about sustainability on the FSC campus

Keri McClure, who is part of the FSC recycling program, started a club on campus at the end of last semester that plans to take action to make our campus more sustainable. It was dubbed Students for a Sustainable Campus, or the "SSC". For anyone who is seeking a "greener" world, this is really something you should look into. I asked Keri a series of questions to give FSC students a bigger picture of how this club came about and where we plan to take it in the next few years. 


What has inspired you to become part of the green movement and your recycling program?
"I started recycling in the spring of my freshman year. I have always taken part in recycling, but never really appreciated its worth until I kind of started on my path towards Environmental Studies and really became much more conscious of my contributions to the world around me (or lack there of) when it comes to recycling. On the same note, I wanted what I did to contribute to the world, the spirit of conservation,and to inspire others with the same sense of integrity concerning their daily actions and their effect on the environment."

How does the student body react towards recycling?
"The reception we get from the campus community is give and take. Some days we hear from people who are really excited about the program and we see that people are very active in the program. On other days we get a hamburger in the bin or something along those line. That just kills the hope we have that people are really on board and just as excited about this program as we are.

Tutus is definitely our biggest contributor followed by JR and Spivey. We also get alot of paper from the religion building, communications, and advancement. I feel as though the staff at FSC is much more on board than the students are.

I think the sense of community that on campus students and staff feel is more complementary to a more active role in recycling. If students feel disconnected from the goal, they are less likely to feel an obligation to make the extra effort to recycle."



When did the SSC come about?
"SSC came about last spring with basically the same idea aforementioned in mind. I wanted more people to become aware of our program and lessen the disconnect. I wanted to start a green movement on campus. The facilities department and staff are very excited about becoming more green. Henry Haywood and Billy Hand have been behind me the whole way."


What are your goals for the SSC?
"Our goals are just to get out there and get established this year. I will graduate in the spring and must pass this group along to someone else next year. I would really love to have a big reception by the student by next year so that the SSC can present at Convocation. The major goals for my term are the reusable water bottle filling stations and the recycling competitions."

What are other colleges and universities doing?
"I learned what other colleges were doing at the Dupont Energy Conservation Conference. Oberlin College in Ohio is quickly moving completely off the gird. Other private colleges in our area are taking part in the Recyclemania competition, campus composting, community produce gardens, black out events (reduce electrical usage), and they have implemented the Presidents Climate Commitment in which they have initiated a climate action plan. One college started a community conservation core in which they helped provide energy conserving products to low income areas, installing energy saving light bulbs, for instance. And so much more!

We are behind, but we can get there and become not only the most beautiful, but the most green as well if we set our goal. The great sense of community that FSC has when directed towards a common goal is an amazing thing that can prove to be the foundation for change at this institution when it comes to sustainability."
