This could be good for Colorado.
I had to watch this video [1] for my biology class. It's interesting how the wolves changed the entire ecosystem by just changing the behavior of deer (they avoided grazing near the river because that's where the wolves wanted to be). The ripple effects are fairly significant.

- davidw 7y agoI had heard things along these lines that that video has been debunked: https://www.accuweather.com/en/weather-news/scientists-debunk-myth-that-yellowstone-wolves-changed-entire-ecosystem-flow-of-rivers/349988 https://www.accuweather.com/en/weather-news/scientists-debun...
- heimatau 7y agoThis is not debunked. Not peer reviewed from what I've gathered from that article, just a lone voice. Yes, ecosystems are very complex but given that complexity, let's not smear an attempt to describe the cause and effect relationship which is assumed, even with your source. Wolves had an effect. Is it overly simplistic in the video I linked? Yes. But is it inaccurate? No. Is there more to learn, describe and understand? Yes.
- duxup 7y agoI saw on a Nova program a while back some scientists doing studies on wildlife just being exposed to the sounds of predators. They recorded predator sounds and setup cameras and speakers to play a predator sound when prey wildlife were near. It changed all sorts of things, including breeding patterns. Also I know the San Diego wild animal park put predator animals upwind of prey animals and saw behavioral changes / different sleeping patterns and more "wild like" behavior just from being exposed to the smell.
