I've mentioned my conch project previously as well. I'll catch you up a bit: I went to Panama to meet the lovely people at STRI and snorkel for West Indian fighting conch. Humans have been harvesting the conch in this area for thousands of years, and there is evidence of size-selective evolution in this species. I wanted to take a look at the DNA of these guys to see what SNPs might have been selected for over time, but I first had to figure out how to get the DNA out of the shells that were left behind.
I presented a poster on this work at the Evolution conference in France last year. Long story short, it looks like the method I developed will work for shells <2,000 years old. The really old shells (5,000-7,000 years) were probably exposed to the sun and heat for too long for the DNA inside to have survived intact enough to be analyzed. I'm currently cleaning up this data, and I can't wait to share the final results with you soon!
I recently shared my Evolution conference poster from this year, which has some VERY PRELIMINARY findings from my lizard project. Humans introduced fire ants to the US in the early 1900s, and they've been preying on lizards ever since. I'm now comparing the DNA of lizard populations from invaded and uninvaded sites across the southeastern US, and will be back with more findings soon.
