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.
