Year in Review: ACE Basin

In September and in December, Kirk and students of Conservation of Marine Resources conducted a quarterly census of blue crabs in the ACE Basin.


The crab catch is down almost 40% from this time last year.


But so is the frequency of the Hematodinium sp. parasite. It appears that above average rainfall this year may have dramatically altered the distribution and frequency of both crabs and parasites.

Year in Review: Florida Keys

In October, our creative inquiry team, Conservation of Marine Resources, conducted a field research project in the Florida Keys National Marine Sanctuary.


I think everyone had a great time, but don't take my word for it. Check out their own blog postings on the CMR web blog at http://clemsonconservation.blogspot.com


TJ finished his field work on octopus behavioral syndromes.


He even got a few more movies of octopus in action while at the lab.


Kaighn and Michael captured a non-native asian swimming crab. This was the first record of this species in the Florida Keys.


It was a perfect place to celebrate a couple of birthdays (Kaighn 21 and Michael 45).

Year in Review: Yellowstone

In May Margaret, Jean and I revisited Yellowstone National Park.


The Druid Peak wolves were back on their ancestral territory in the Lamar Valley. We saw the pack nearly everyday during our visit.


As a result, most of the elk, sheep and mule deer remained vigilant when grazing in the valley.


However, this young moose had a different strategy choosing the safety of a back-yard salt-like in Cooke City.


Did I mention that we also saw a lot of bears? Fortunately, not the one that made this track on the trail we were hiking.

Year in Review: Hawaii

In May, I spent three weeks helping Margaret and Kristine with their incredible waterfall-climbing goby research on the Big Island of Hawaii.


On our days off, we explored the coast on snorkel, by kayak and on SCUBA.


We were treated to many wonderful marine invertebrates...


amazing reef fishes...


green sea turtles...


and acrobatic manta rays!

2009 Benthic Ecology Meeting


The strong, warm winds blowing off the Gulf of Mexico brought a spring-like atmosphere to Corpus Christi and the 2009 BEM. Kirk, TJ and Michael all gave presentations, played some animated racketball, and enjoyed the banquet aboard the USS Lexington.

It's good to be back in the Keys

Ah, back in the Keys again for the summer. After a long and harrowing trip down last Saturday, TJ and I arrived to bright sunny skys, azure blue water, and fish looking at us pleadingly from the water (please fish for me, please). Before we could go fishing though (okay, after we went fishing, but only once. . . ), we needed to to do a bit of work to start off the summer, namely check the collectors for baby lobsters (or puerulus postlarvae as we lobster nerds like to say). We picked up our intrepid leader (Michael) from the airport in Miami on Tuesday and headed out to check the collectors on Friday, which had been floating on the ocean side of Long and Matecumbe Keys since late March of this year, accumulating lots of algae, sediment, and yes, tiny, clear, and exceedingly cute baby lobsters like the one you see on my finger above. Forget baby dolphins, baby lobsters are way cuter. . .


Checking collectors, such as the one you see above could be construed as hard work, even on a gorgeous sunny day like yesterday. First the boat approaches the collector, moving into the wind. Next Pete reaches down with a giant bag and captures the collector, which is floating about a foot under the water. TJ unhooks the whole shootin' match from the anchor and Pete hauls it all on board. Next, each section of the collector (sheets of genuine hogs hair filter material made for industrial air handling units) is checked meticulously for little lobsters, many of which are completely transparent.


Some, like those you see above, are a bit easier to spot. The little stripy lobsters are 1st, 2nd, and 3rd stages, which have probably been on the collectors for over a month now. After checking, the collectors go back into the water for another few days, before they are pulled again. After 28 collectors, my arms felt like they were about to fall off. But it was all worth it for the little buggers you see below.


The striped pattern on the lobster helps it hid in the algae habitat it normally would settle in, but makes it stand out a bit against the blue hogs hair. All the better for us. We had a pretty good haul and ended up with about 450 lobsters total in two buckets.


What can I say. I was a hot day and I was really dirty. . . not a bad time for a swim once that 28th collector was back in the water. After we got back to the house, we tagged all the lobsters with a little magnetic piece of wire. A very expensive and delicate machine injects these through the needle you see below into the tail of the lobster. We can then release these tiny modified Robo-lobsters back on to our sites. Every month, we will take the metal detector and check each lobster to see if it is one that we released.


Not bad for a day's work. Tomorrow we seed the lobsters onto the sites, should be fun!
