-A motivated team of Georgia Institute of Technology undergraduates created an amazing video highlighting our research paper "The key ecological trait drove the evolution of evolution of biparental care and monogamy in amphibian."


The video is aimed to explain an evolutionary concept to advanced high school students. Check it out. Great job team poison frog!

- An answered call. A lab paper (Barrett et al. 2010) entitled "Modeling the effects of illicit rosewood logging in Madagascar: A call for CITES designation" was recently used as evidence to support the listing of Malagasy Dalbergia spp. under CITES protection. Today we learned that it was approved. Cheers to science in action! See our Nature paper summarizing this!
