Shark-tooth weapons reveal lost biodiversity : Nature News & Comment
Sean Connolly, a marine ecologist at James Cook University in Townsville, Australia, says that historical studies such as Drew's are crucial, because there is a lack of good ecological data on shark populations before humans started to change the oceans significantly. “Such data are essential for the reconstruction of realistic ecological baselines against which we can compare the current status of the world’s marine ecosystems,” he says.
“When we set up modern conservation plans, we shouldn’t sell ourselves short,” says Drew. “We might not recapture the vivid splendour of those super-rich levels, but this information argues for setting up management plans to protect what sharks are there.”
