Melissa Giresi is currently a PhD candidate in the Department of Biology at Texas A&M University interested in using genetic methods to assess population structure, connectivity and biodiversity of exploited marine fishes and invertebrates. For her dissertation, she is testing the null hypothesis that the dusky smoothhound shark, Mustelus canis, is a single genetically-panmictic population in U.S. waters and utilizing molecular and morphological markers to assess how many smoothhound species are present in the Gulf of Mexico. She is also involved with projects to investigate population connectivity in fine tooth sharks, black nose sharks, cobia, and amberjack.

On Thursday, I tweeted “Name the most influential female ecologist (alive today) that you can think of.” After it was re-tweeted by several of my much more twitter-savvy colleagues and friends, I received an overwhelming number of responses. In retrospect, I should have created a hashtag to keep track of the responses. Forty-five influential female ecologists were named in this search, some of whom responded to the question themselves, naming their colleagues (but never naming themselves). The most influential female ecologists (alive today) according to the twitter-verse are listed in the table below in alphabetical order by last name.

This past Tuesday, the draft bill to reauthorize the Magnuson-Stevens Act was released by the U.S. House. The Magnuson-Stevens Act is a big deal because this is the law that lays out how fisheries management works in the United States. This time, a number of changes have been proposed by Representative Doc Hastings, some of which could fundamentally change fisheries management and fisheries science in U.S. waters. The proposed changes immediately became controversial, garnering overwhelming support from witnesses to the House Natural Resources Committee hearing of the bill (witnesses included representatives from the recreational and commercial fishing industries as well as the Mid-Atlantic Fishery Management Council) while the Pew Charitable Trust strongly opposed the bill, calling it the “Empty Oceans Act” (translated into GIFs by Upwell for your viewing pleasure).
How might the Hastings bill affect your favorite marine species (both in the water and on your dinner plate)? Read on to see the good, bad, and ugly aspects of these proposed changes, at least according to this particular fisheries scientist.

Hello, dear internets! Thank you for the warm welcome. I am extremely excited to be joining Southern Fried Science—talk about being in good company! For those of you who don’t know me, I am a student at the University of Oregon, where I study marine biology and journalism. I love all things science, but I have a small (ok, not so small) love for shark biology. I look forward to promoting ocean outreach through kick-ass science communication with the rest of the team, here at SFS.
Enough about me, on to some animal insides.
In honor of #unshark week’s end, I return to the awesome that is shark science. Like skates and rays, sharks are chondrichthyans, cartilaginous fishes whose skeletons are made primarily of cartilage rather than bone. Ever wonder what a mostly-boneless skeleton looks like? Sure you have (and if not, you are now thinking about it and the suspense is killing you, I say).
Shark skeletons are complex, beautiful, and thanks to Dr. Gavin Naylor, and his team at College of Charleston Naylor Lab, they are here for you to see.

For more than 5 years, Southern Fried Science has shared incisive, clever, humorous, informative, and educational ocean science and conservation stories. Our content has always been free, and, with the exception of one brief experiment, ad-free. Our writers are volunteers. Our tech support donates his time and expertise to keep the site running smoothly (for transparency’s sake, Andrew does the site maintenance and conducted the recent complete redesign of the site) . Our most senior members pay our server hosting fees out of pocket. Southern Fried Science occupies an important niche in the marine science and conservation community.
We’ve grown. Last year we brought in over 1,000,000 unique visitors. Growth comes with additional costs, in both hosting fees and maintenance time. Our budget isn’t huge, but it is tight.
If you enjoy this site, please consider contributing a few dollars to help cover our costs. We’ve set up a few different option on the Support Southern Fried Science Page. You can subscribe to make a recurring monthly payment (expires after 12 months) or a one-time donation. Donations will go towards server hosting costs, compensating our tech support for his time, and funding exciting new projects.

I am participating in the 4th SciFund Challenge, a crowdfunding event for scientific research! My project, part of my Ph.D. dissertation research, is looking at the feeding ecology of local species of sharks with the goal of generating data that can help managers to conserve and protect these species. I’d appreciate any assistance you can provide in terms of either donating funds to the project or helping to spread the word.
A donation of any size is helpful, but larger donations have rewards associated with them, including the opportunity to join us for a day of shark research, or the opportunity to name one of our satellite tagged sharks and track it on Google Earth.
I’ll post frequent updates here, on twitter, and on my Facebook page. Please let me know if you have any questions about the project!
My project can be found here.

Almost four months ago, I sat down at my computer with a puzzle to solve: is there an easy way to model sea level rise without using expensive GIS programs. I found that solution in Google Earth and, after a few days of experimenting and tweeking, #DrownYourTown was born.
1 meter of sea level rise would make for a very soggy superbowl.
#DrownYourTown is a tool for exploring sea level rise through real-time, interactive, GIS modeling. Anyone can submit a request via twitter or tumblr and receive a custom, 3D model of sea level rise anywhere in the world. The system allows users to produce dramatic visuals of both plausible and implausible climate change scenarios. The project is ongoing, with user generated content, an active tumblog, and a vibrant twitter community centered around the hashtag. I am constantly exploring new ways to reach a broader audience. Currently, #DrownYourTown is on a virtual road trip, visiting a new coastal state each day, and cruising through towns after 5 meters of sea level rise.
#DrownYourTown has been an exciting and sometimes humbling journey. Here are four lessons about climate change outreach I learned from drowning your town.

Dr. Steve Palumbi studies the genetics, evolution, conservation, population biology and systematics of a diverse array of marine organisms. Along with Tony Palumbi he is the author of the forthcoming book The Extreme Life of the Sea. UnShark Week is a week long celebration of the ocean’s extremes.
Dr. Palumbi, enjoying a day at the beach.
Since 1987, the Discovery Channel’s annual Shark Week pumps up the thrill of encountering a dangerous shark. Teeth, danger, lunging predation, more teeth: this is what the week is mostly about. But most of the extreme species in the sea are not sharks. Sharks are not the biggest, the deepest, the fastest, even the deadliest. This week is exactly midway between Shark Weeks, 26 weeks till the next one; 26 weeks since the last. And because there are so many other thrilling species in the sea, we declare this week as UnShark Week – and dedicate it to the truly extreme animals in the ocean.
The fastest fish in the sea is not a shark. Sailfish have the unofficial record at 60 mph, and well documented speed trails have clocked tuna and wahoo at nearly 50 mph. By contrast the most celebrated human swimmers manage 6-7 mph. Billfish like marlin and sailfish feed at such high speeds that their brains and eyes can not operate fast enough. So as an adaptation to speed, these fish have evolved heaters in the brains and eyes so they can form and process images fast enough to snap up prey in high velocity sorties.

Aquaman #27. DC Comics.
It’s been more than 2 months since we last discussed the patron saint of Southern Fried Science, the one and only Aquaman. The Atlantean übermensch has a new lead writer, Jeff Parker, who’s teamed up with Aquaman veteran Paul Pelletier to produce an engaging and visually stunning story. After the epic conclusion to Throne of Atlantis, Aquaman is off on an entirely new adventure. Unfortunately, this new quest puts our hero in the path of a gargantuan guardian of ancient Atlantis, the Karaqan!
The Karaqan is big, but just how big is it? How does the Karaqan stack up against living sea creatures? Could an arthropod ever get as big as the Karaqan? Most important, if Aquaman does successfully slay the Karaqan, just how much Old Bay would we need to steam it?
