The Changing Face of Ecology: Part Two

Ecology is a discipline that is constantly evolving. I spoke to (from left to right) Ian Winfield, Cory Coldsworthy, Matt von Konrat and (not pictured) Don Schreiner and Sean Connolly about the biggest changes they've seen in their careers

Two weeks ago, I published Part One of our look into how ecology has changed over recent decades. My colleague Kate Layton-Matthews and I have put this question to a number of ecological researchers from all over the world. Here are some more responses on how our field has evolved, from the publishing of papers to land clearance to the job market.

I spoke with Don Pereira, Don Schreiner and Cory Goldsworthy of the Minnesota Department of Natural Resources (MNDNR) and Minnesota Sea Grant (MNSG) about one of the rare success stories of invasion ecology.
