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.
