The SciFund Challenge came to a close last night. In total, more than 15 projects, including mine, were fully funded! More than $45,000 was raised for scientific research! My minimum funding goal for this project was $3,000, an amount which would have allowed me to use stable isotope analysis to study the feeding ecology of … Read More “Thanks for your support of my SciFund crowdfunded shark research!” »

Thanks to the 73 people who have donated to my SciFund Challenge shark feeding ecology project so far, helping me to meet and surpass my minimum funding goal! I can still accept additional funds beyond my minimum funding goal, and all funds raised will still be used exclusively for lab processing fees.  As before, donations … Read More “Want to name a shark and track it with Google Earth?

After one week, my SciFund project is more than 70% funded! Thanks to the 50 people who have donated so far! I’m making lots of progress, but I still need your help to make sure the project gets completely funded. Any donation helps, but larger donations have rewards, including getting to join me for a … Read More “Want to participate in a day of shark field research? Donate to my SciFund project!” »

SciFund Challenge: Help support my shark feeding ecology research

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 … Read More “SciFund Challenge: Help support my shark feeding ecology research” »

SciFund challenge background: 6 questions you can answer about shark feeding ecology with stable isotope analysis

scifundAs many of you have heard, I have a project in the 4th SciFund Challenge, a scientific research crowdfunding organization.  My project, entitled “You are what you eat: non-lethal feeding ecology to help conserve threatened sharks,” is part of my Ph.D. dissertation research. You’ll be hearing a lot more about it over the new few weeks here, on twitter, and on my Facebook page once the challenge officially starts on February 1st. I’d really appreciate your support of my research!

I’ll be using a research technique called stable isotope analysis to study the diet and food web interactions of shark species in Florida. My project (and the research technique) will be briefly explained on my SciFund site, but I wanted to go into more detail about the type of research questions that stable isotope analysis can answer, as well as why this kind of data is significant.

Feeding ecology is important to the conservation and management of sharks.

An emerging trend in marine conservation is “ecosystem based fisheries management”, which means that managers would consider the diet and food web interactions of species of interest. An effective ecosystem-based fisheries management plan would require, among other things, detailed diet and food web interaction data. We can better conserve and protect threatened marine life such as sharks if we better understand their biology and ecology, including what they eat. Over 100 priority research questions for shark conservation were identified in a 2011 research paper (available open access here), and several of these are related to feeding ecology and ecosystem role.

The traditional method for studying the diet of sharks is called stomach content analysis, which typically involves cutting open the stomach of a shark to examine what is inside. Southern Fried Science writer Chuck used a non-lethal alternative that involved pumping the sharks’ stomachs, but that is far less commonly performed. While direct and effective, this kind of lethal sampling research may not be appropriate for certain threatened species of sharks. Stable isotope analysis, which requires only a small tissue sample, can be performed non-lethally.
