Tarpon: How does this chemistry thing work anyway?

Ok, so this project sounds cool. Using tarpon scales to understand where tarpon migrate throughout their life. But that also sounds impossible. How does it work?That's what I'd like to talk about t...

Tarpon! Cool fish, cool science questions.

Half of the work for this project is to understand the movement of Atlantic tarpon. So, why is it that tarpon are even interesting scientifically?Tarpon are interesting to me partly because they ar...

Thanks! I'm glad you liked this report. It's fascinating science. I'll have to pick that book up, I have not read it.

Could teeth and scale chemistry reveal threatened Amazonian mega-fish movements?
View comment
I share your bias! I do think that this project has big potential. I believe, at this point, that I have one of the largest collections of sawfish samples in the Americas, and the Amazon region is very poorly understood despite being a refuge for the species. I think we'll learn some cool things. And that's even before we get to the tarpon samples. I'm excited by the potential! Thanks for your donation!

Biological control of the mosquito Aedes aegypti

No problem. Get in touch if you need any specific names. I have that thesis tucked away somewhere. They were using R. Iyengari I believe, or perhaps also R. Culicivorax and had a whole system for mass producing them for dispersal into seasonal ponds. I never heard what the end result was but it made for an interesting senior thesis.

I did a senior thesis with the Roraima Secretary of Health looking at efficacy of similar nemotodes on malarial mosquitos. It was a joint project with the Cuban government in Boa Vista, Roraima. Do you know of that work? They may have knowledge about scaling this up in the future. I like your project! Good luck.

Can sloths serve as “canaries in the coal mine” for forest health today and in the past?

Awesome! Hey cousin! Thanks for the donation and also thanks for the tip. It took me a second to find, it's .org, but wow that is super cool. I've honestly been trying on a small scale to do this sort of semi-automated analysis with otolith analysis in my lab group. I don't have enough samples to make it worth their time...but who knows about the future. I like these sorts of citizen science ideas for big data. Reminds me of the SETI screensaver from the old days.

Excellent! I hear Stephen is playing a concert with a pretty incredible piano player this week. Thanks for the book recommendation and the vote of confidence. I'll certainly be sharing on Facebook over the coming month. Keep in touch.

Big Fish a Long Way from Home: Using ear bones and teeth to unravel migration in Amazonian fish
View comment
I'm really excited by the project, and I think it's really timely. We were the first to use this isotopic technique but just the other day another paper was posted in pre-print with a very similar study that confirmed our earlier results (http://bit.ly/1S49pPr , paywall I can send the PDF if anyone wants to read it). Another group also just submitted a paper. Unfortunately, the pace of dam building is what is finally spurring people to do this work...along with the fact that until last year there weren't good baselines for the isotopic chemistry of the river or techniques like ours to predict it. So, there's a convergence of really urgent need and technological ability that makes this possible finally.
