Sea Turtle Conservation Gets Boost From New DNA Detection Method

A study led by University of Florida researchers is the first to sequence environmental DNA, or eDNA, from sea turtles — genetic material shed as they travel over beaches and in water. The research project is also the first to successfully collect animal eDNA from beach sand. The techniques could be used to trace and study other kinds of wildlife, advancing research and informing conservation strategies.

Can Handheld DNA Testing Technology Stand Up to Seafood Fraud?

When LeeAnn Applewhite started running DNA analysis on commercial seafood samples in 2015, 75 percent of them – species ranging from grouper and snapper to catfish and shrimp – were mislabeled. “We were testing thousands of samples, and some of it was unintentional mislabeling; it was a bycatch species with [species like] grouper or snapper but the whole load was not erroneously labeled,” said Applewhite, co-founder and president of UF Innovate | Sid Martin Biotech graduate Applied Food Technologies.
