During their visit to FSUCML, Randall took the SciGirls to the small marsh next to the lab. One SciGirl found this fiddler crab carrying her eggs.
This video is part of the WFSU SciGirls project. SciGirls, for those who haven’t heard of it, addresses an unfortunate reality in the world of science- there are a lot more men doing research than women. It’s a problem that needs to be addressed as interest in science as a career has been waning overall. Every Summer, the SciGirls camp takes groups of teen and preteen girls into labs and into the field with scientists. After visiting Dr. Randall Hughes at the Florida State University Coastal & Marine Laboratory last Summer, a couple of SciGirls returned to conduct this interview.
Randall is a good role model for young aspiring female scientists. Aside from the fact that she herself is a female scientist, most of her lab- and that of her colleague Dr. David Kimbro- are females as well. If you’ve been following this blog, you’ve read about Emily Field’s graduate work on seagrass wrack and Kattie Lotterhos’ graduate work in genetics. In David’s lab, we’ve heard from Tanya Rogers, a lab technician who keeps David’s lab organized, and who is crucial in the planning and implementation of their large field experiments. We have more recently started hearing from Hanna Garland, Tanya’s fellow lab tech who is starting graduate school in the fall and who is looking into the abnormal levels of crown conchs on Randall and David’s Saint Augustine reefs. And we have also heard from Cristina Lima Martinez, an intern who comes to the Kimbro lab from Spain to study the Bay Mouth Bar ecosystem.
We spent one day learning about invasive Hydrilla and alligators at Wakulla Springs, and then of course had to cool off!
For most of the month of May, I was busy teaching an undergraduate course at FSUCML. The course – Marine Biodiversity and Conservation in Florida – was a new offering, and it was lots of fun to put together. And, at least from my perspective, it went pretty well! (I guess you’d have to poll my students to get the true picture of how it went down.)
One of the best aspects of the course, for me, was to learn so much about the special part of Florida that we call home. We spent one day trying our hand at tonging oysters in Apalachicola, Continue reading →
A little over a year ago, when the FSU Coastal & Marine Laboratory and WFSU-TV – a TV station – started this online enterprise, the understanding was that at some point this would end up being a show. And so here we are. As you may have gathered from that video up there, this will be about predators and prey: who’s eating whom, and who’s scaring whom. We will of course be doing this through the prism of David and Randall’s studies: the consumptive and non-consumptive effects of predators in salt marshes and oyster reefs, and the methods used to shine a light on these interactions.

Emily holds a net that will soon be full of marsh bugs. Later, at the lab, she will identify the many insect species that live amongst fiddlers and periwinkles, species more often associated with the habitat.
Several weeks ago, I went to Houston to meet Thomas Decker, a tech in Steve Pennings’ lab at the University of Houston. Thomas graciously offered up his time to help me with my insect identifications. I have absolutely zero background in entomology, the study of bugs and other creepy crawlies most people squirm about. So how did I end up spending hours puzzling through an identification book on insects, a book with so many unfamiliar terms that I was constantly flipping to the glossary and various diagrams? Silly me, I decided that I needed to include the terrestrial part of my salt marsh community. Which meant I have spent quite a bit of one-on-one time with a dichotomous key on insects. A dichotomous key is a “choose your own adventure” style guide to identification. Continue reading →
Where did my winter of catching up on work go? And why is spring quickly hurtling into summer? YIKES!
…Okay, I feel better. All of us here feel a little behind on things, because this past winter and spring have been full of other projects (in addition to the oyster one) such as investigating how the oil spill affected marshes throughout the west coast of Florida and examining what all of those snails are up to out on Bay Mouth Bar. But now that summer is almost upon us, it’s time to move all hands on deck back towards the ambitious summer oyster goals.
Environmental vs. Predator Effects.
To lay the ground work for this summer’s oyster research, I spent a few days in St. Augustine, Florida, which is where we will conduct our colossal field experiment. As a recap of the oyster objectives, we spent year 1 monitoring the oyster food web at 12 estuaries between Florida to North Carolina. Well, we found some cool patterns regarding the food web and water-filtration/ nutrient cycling services on oyster reefs (see the 2010 wrap-up). So, now we want to know what’s causing those patterns. Are differences in oyster reefs between NC to FL due purely to differences in water temperature, salinity, or food for oysters (phytoplankton)? Or, do we have a higher diversity of predators down south that are exerting more “top-down” pressure on the southern reefs? Or, is it a combination of the environment and predators?

It kind of looks like one of those vintage ’80’s jackets adorned with mirrors and sequins- mollusk style. This horse conch’s got a little bit of everything on it, the result of an interesting reversal of roles in this seagrass bed on Bay Mouth Bar.
When I heard it was supposed to rain on Saturday, I was a little bummed. I was planning on taking the family to the FSU Coastal and Marine Lab Open House followed by the FSU Spring Game (where my 12-week old son could attend his first football game featuring my two favorite teams). Luckily, the storms rolled through early in the morning and made for a nice day at the coast.
I started off by visiting my friends at the Randall Hughes and David Kimbro labs. Robyn and Emily held down the fort in the Hughes lab, where kids watched a very peculiar sport. As Randall’s previous post promised, there were indeed periwinkle snail races. As you can see from the photo at the right here, the snails were color coded (white and blue) and numbered so that they could be told apart. Some crown conchs (periwinkle predators) were placed into the tubs to give the smaller snails some incentive to climb. The fastest climbers won. Let’s watch part of one race:
Writing grants, collecting field data, looking at samples in the lab- activities such as these occupy the majority of a researcher’s time. But sharing why the subject of the research is cool and interesting with the public is an important part of the job as well.

If you’ve been holding back your comments and questions as you read the blog, then this weekend is your chance to ask them in person! David and I, along with our graduate students and technicians, will be participating in the FSU Coastal and Marine Lab Open House on Saturday from 10:00am to 3:00pm.
I have known John Spohrer since the late 1980’s, when he was introduced to me as one of the locals who lived year-round on St. George Island. I often rented houses with friends for weekends on the island back in those wacky 80’s and 90’s and he was always a welcome addition to whatever revelry would breakout in our kitchen, on our deck or on the beach.

When we look at a salt marsh, we see thousands of stems of cordgrass. But in reality, the coastline may be made up of only a few different genetic individuals. This is because Spartina can spread by growing clones of itself, with the exact same genetic code (a genotype). Why does it matter if we know whether or not a salt marsh is made up of one or many different genotypes? Well, different genotypes will have different abilities to resist pests or disease, or they may be tastier to eat for the little marsh critters like snails and grasshoppers. Since some genotypes will be better than others in different situations, we care about genetic diversity because it can be a buffer against an uncertain environment.
