As promised, here are the results of my first ever PCR. Here is some background:
I am going to be running some population genetics on sandbar shark DNA with the intention of comparing subpopulations from South Carolina with those from Virginia.
I am in the very early stages- seeing which primers work for PCR. Four primers each were tested- called A, B, C and D- on three shark DNA samples and a negative control. Ignore the samples on the bottom, they are from another student’s project. The four samples in the upper right are my negative controls.
The PCR was run yesterday (my first PCR), and I ran the gel today (my first gel).
It seems to me that Primer A is successfully copying my DNA during PCR, while B, C, and D are not.
I am pleased to present the first in a new series of posts here at Southern Fried Science- reader mail. If a reader has a question for us, shoot us an e-mail with the subject “reader mail” and we may answer it for you on the blog. Our first questions are about my new shark conservation documentary:

Edward Dorson, the Director of Conservation Strategies for the Shark Research Institute, has published an excellent editorial about CITES in the Gulf Times, which describes itself as “Qatar’s top-selling English daily newspaper”. The editorial can be found here. Here are some highlights, though I recommend reading the whole article. “All trade in a species vanishes … Read More “A cry for reason at CITES” »
One week after the world premier at the Benthic Ecology conference’s Beneath the Waves Film Festival, I am pleased to announce that my new shark conservation mini-documentary, “four things everyone needs to know about sharks”, is now available on YouTube.
Check it out here:
If you are an educator, the movie is intended to be part of a lesson plan about shark conservation. I have created a middle school version, a high school version, and a college version. Contact me at WhySharksMatter AT gmail DOT com with the subject “Shark Lesson Plan” and I’ll send you what I have, or we can discuss making a custom lesson plan that suits the specific needs of your class.
If you are not an educator but care about sharks, the movie can be a stand-alone way to educate your friends, family, coworkers, classmates, etc.
Please let me know what you think about the video by commenting on this blog post.
Thanks to all of my photographer and musician partners in this project!

The latest news out of CITES isn’t encouraging. Marie Levine, President of the Shark Research Institute, is attending and made the following statement: “Animals did not fare well at CITES today. The USA’s bid to have the polar bear uplisted from Appendix II to Appendix I was defeated, as was Egypt’s attempt to have the … Read More “CITES update: Bluefin and crocodiles and polar bears?

The first shark conservation proposal at CITES has been defeated. This was not a proposed appendix II listing that I wrote about yesterday, but rather a nonbinding measure that “called for increased transparency in the shark trade and more research into the threat posed to sharks by illegal fishing” (from the AP article linked to above). If a non-binding measure that doesn’t actually ban any trade in shark products can’t pass, that’s not a good sign. Why did some countries vote against this non-binding measure to support research and increase transparency?

The 15th meeting of the Convention on the International Trade in Endangered Species of Wild Fauna and Flora, also known as CITES, has begun, and representatives of 175 countries are meeting in Doha, Qatar. CITES rules have the power to make international trade of plant and animal species illegal, which has enormous significance for their conservation. 8 shark species have been proposed for CITES protection under appendix II- oceanic whitetip sharks, porbeagle sharks, spiny dogfish (commonly used for fish and chips in the UK), dusky sharks, three species of hammerheads (great, smooth, and scalloped), and my study animal the sandbar shark.
Recently, Andrew attempted to correct several commonly-held misconceptions about sharks. He raises some good points, but I disagree with his conclusions. I believe that sharks are incredible animals, but I think it is far more relevant that sharks are important animals.

It has been an exciting week for shark conservation! We can only hope that this provides some momentum for CITES, which begins tomorrow. And now, for this week’s shark conservation news: The Indian Ocean Tuna Commission declared a ban on commercial landings of all thresher sharks (each of the three thresher shark species is considered … Read More “Shark conservation news: Fisheries closures, fish and chips, and a new shark sanctuary” »
