What Have Seagrasses Done For Me Lately?

Episode 6: Blue Carbon Where the Stingray Meets the Horse Conch

At the beginning of September, Randall and David had a visit from Dr. Peter Macreadie of the University of Technology, Sydney.  In this video, Randall takes Dr. Macreadie for a snorkel in St. Joseph Bay.

We now focus our attention to seagrasses, which as it turns out, often don’t get a lot of attention, at least in comparison to other marine habitats like coral reefs or even salt marshes.

In part, this lack of attention is due to the fact that seagrasses typically live completely underwater, except at very low tide, and so they are not as noticeable as marshes are. In addition, seagrasses often occur in shallow estuaries not known for their great visibility (and thus not as ideal a location as coral reefs for snorkelers or scuba divers). And, although I disagree, some people just don’t find them very pretty.

Last week as I was starting to think about this post, there was a small uptick in the number of media articles related to seagrasses, at least in Australia. The increased interest was in response to a proposal by the Environment Minister, Tony Burke, to require greater seagrass protection from mining and development projects (read more in this article from the Brisbane Times). As justification for the increased financial burden on companies, Mr. Burke cited the many benefits that seagrasses provide. And just what are those?

Scallop in St. Joseph BaySeagrasses (like salt marshes and oyster reefs) provide habitat for many, many fishes and invertebrates. Studies have found that the number of animals living in seagrasses beds can be an order of magnitude higher than the number living in adjacent coastal habitats. Many of these animals rely on the seagrass beds as a “nursery” that protects them from predators until they grow larger. And lots are recreationally and commercially important species that we like to eat. (Scallops, anyone?)

Seagrasses are also incredibly productive plants, sometimes growing more than 1cm per day, and rivaling our most productive crop species like corn. Because a significant portion of this plant material (particularly the roots and rhizomes below ground) stays in place once the plants die, seagrasses can also serve as important ‘carbon sinks’, or buried reservoirs of carbon. In fact, a recent study estimates that the carbon stored in the sediments of seagrass beds is on par with that stored in the sediments of forests on land!

Although lots of the productivity of seagrass beds makes its way underground, some of it does get eaten. Major consumers of seagrasses include urchins and fishes, as well as the more charismatic dugongs, manatees, and sea turtles.

Spider Crab in St. Joe BaySeagrasses (like salt marshes) also play an important role in reducing nutrients that run off from land into the water. Unfortunately, these nutrients can also lead to the loss of seagrasses, by promoting increased growth of algal “epiphytes” that grow on the blades of the seagrasses themselves. When there are not enough small fishes and invertebrates around to eat these algae, they can overgrow and outcompete the seagrass, leading to its decline. And when the seagrasses become less abundant, the animals that rely on them are also often in danger.

The Big Bend and Panhandle of Florida are home to expansive seagrass beds that also often go unnoticed. But they contribute to the productivity, diversity, and beauty of this area in many ways, as anyone who has been scalloping recently has surely realized!

Lionfish

Lionfish 3For the next year, harvesting lionfish will no longer require a fishing license when using certain gear. The recreational and commercial bag limits have also been removed. These changes are effective through August 2013. The Florida Fish and Wildlife Conservation Commission is hopeful that the changes will increase harvest opportunities of this nonnative invasive species in the Gulf of Mexico.  For more information on lionfish and the new harvest regulations view this FWC news release.

Lucky for us, these invasive lionfish are delicious. Give these Hot Lionfish Poppers a try after a long day of harvesting.

Crab Trap Closures

Derelict crab trap 3Blue crab trap closures began last week for Florida. These two 10-day trap closures give the Florida Fish and Wildlife Conservation Commission the opportunity to identify and retrieve lost or abandoned traps that could become a problem for the marine environment. The scheduled closures vary by region. For more information on  the closures or the trap-retrieval program visit this FWC news release.

 Inspiring Adventures

Author Peter Heller sat down with Fresh Air host Terry Gross for an interview about his debut novel, The Dog Stars. An expedition kayaker, Heller explains how he draws inspiration through his often-dangerous adventures and how he relates his experiences to those of his characters. To learn more about Heller’s new novel and his paddling journeys, listen to the full interview on the NPR Books blog.

Safe Sun

Scientists from the University of Strathclyde are looking to put an end to outdoor clock-watching and blistered skin. They’ve created an ultraviolet-ray-detecting wristband that will give a visual warning that you’ve been in the sun long enough, using an acid detecting trigger that will turn the band from yellow to pink. Partners in the project are hopeful that the wristband will be available in spring 2013. Read more about the wristband, and the technology behind it, here.

On WFSU-TV

This Wednesday on WFSU-TV’s dimensions, viewers will be taken to various state parks in our viewing area. This one-tank-adventure will also bring us to Grayton Beach, near where producer Rob Diaz de Villegas shot a previous dimensions segment on the 2008 Back to Nature Festival.

FSU Coastal & Marine Lab news

Construction on a new FSUCML research vessel began in early January 2012.  The custom design is tailored for coastal and offshore research in the Gulf of Mexico. The new vessel will have more space and stability than the previous vessel, and will also allow easy adaptation for the specific needs of individual research projects. Visit the FSU Coastal and Marine Lab site to follow the construction progress. (Photo copyright FSU Coastal and Marine Lab)

Corine Samaras is an undergraduate student in the certificate program at the Florida State University. She will be working with Deep-C Consortium on an experiment to study how crude oil from the Deepwater Horizon oil spill decomposes in Gulf of Mexico sediments. You can follow her experiment through her blog on the Deep-C Consortium site.

RESTORE Act

After two years, a deal has been reached concerning potential fine money that BP will pay for its role in the 2010 oil spill. Under the RESTORE Act, 80% of the money levied will go to the Gulf Coast states-Alabama, Florida, Louisiana, Mississippi and Texas, with up to 21 billion dollars flooding into Florida’s panhandle counties.  As this Tallahassee Democrat blog post points out, this money could be a boon to our area.  Florida’s money will be distributed by the Governor’s office.  The Northwest Florida Daily News reports that officials from panhandle counties are wary of how the state will decide to divide the money.

Florida Regulators Request Standard for Mercury Levels in Fish

Mercury contamination in fish is a global problem. Florida environmental regulators are looking to set standards for the maximum amount of mercury allowed in the state’s fish to make them safer to eat. Studies show that human activity is responsible for two-thirds of the mercury contamination in Florida. Environmental officials are holding public meetings and will continue to to take public input on the issue until August 27th. They will then publish a mercury-level recommendation for approval by the U.S. Environmental Protection Agency. If you missed it, listen to this WFSU-FM story for more information.

The Combined Benefits of Research and Teaching

Dr. Randall Hughes FSU Coastal & Marine Lab

I recently completed teaching a 2-week course in Field Marine Science at FSUCML. Nine undergraduate students and one graduate teaching assistant lived in housing at the lab for the duration of the course, and we were busy from virtually sun-up to sun-down each weekday with class activities. It was a lot of fun:

PICT0102

A group of students works to complete our field survey before the sun sets.

This year, we focused on oyster reef ecosystems, taking advantage of past and ongoing projects in the Hughes and Kimbro (aka, “Hug-bro”) labs. We conducted a field experiment, field survey, and mesocosm experiment examining sediment accumulation on oyster reefs – and all in just 2 weeks!

IMG_2566

Students quantify sediment accumulation on oyster shells during our field experiment.

Students process the contents of cages from our field experiment, looking for crabs.

Well, the field experiment and survey were started ahead of time by Hugbro personnel, but the labor-intensive breakdown and sample processing tasks were handled by the class.

After all that time spent learning about, walking around on, and handling oysters, everyone was ready to eat a few by the end of the second week!

PICT0099

An underwater camera gave us a great view of the seagrass!

In addition to gaining hands-on research experience, a goal of the class was to become familiar with common coastal habitats in northern FL. So we squeezed in a few trips to seagrass beds and salt marshes as well, enjoying the opportunity to ride on a boat that didn’t require paddles.

Happily preparing to snorkel in St. Joseph Bay State Park, FL.

We observed lots of sea hares as we snorkeled in St. Joe Bay.

And we were all happy to don snorkels and masks to explore the seagrass instead of gloves and boots for the oysters!

Slide1

Results of a study by Feldon and colleagues demonstrating an increase in the quality of hypotheses included in graduate student research proposals when the students had teaching responsibilities.

As I catch up on the research projects that languished a bit while I was teaching, it is reassuring to think about the results of a recent study illustrating that teaching can increase the quality of research. Don’t get me wrong – I enjoy and value teaching for its own sake – but the tasks of teaching and research can often seem in competition with one another when time is limited (and when is time not limited?).

Slide2

Additional results from the study by Feldon et al. showing better experimental design in research proposals written by graduate students that teach and do research.

Enter the study by Feldon and colleagues in the journal Science, showing that graduate students with teaching responsibilities formed better hypotheses and generated better experimental designs in their own research proposals than graduate students without teaching responsibilities. This benefit did not result from explicit instruction in hypothesis testing or experimental design geared towards the graduate students themselves – rather, the process of teaching scientific concepts to others made them better able to conduct research. So add to the inherent fun and satisfaction of teaching a boost to my research! Time to write a (better?) research proposal…
