What is a trophic cascade and how exactly do wolves change rivers?

When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable " trophic cascade " occurred.





Nature is so far beyond our direct control. This is a cool short little film.

trophic cascade, an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain, which often results in dramatic changes in ecosystem structure and nutrient cycling.

The howling wolves got the Border Collies attention!
Nice video. Perhaps this would be a good spot to relocate a beaver to?

Wolves are so cool..... I wish somebody would put a wolf on a T-shirt.
Maybe even 2 or 3 wolves.
And what would be even cooler? Have them howling at a moon.



Naah.... That would just be too much awesomeness for one shirt.

Or, how about a nearly naked amazon (dressed in leather straps and carrying some kind of a weapon) walking an Indian path with a pet wolf at her heel....during a full moon!

Yeah! The wizard in a cloud, like a dream, casting spells with sparkley magic dust coming off his long fingers and a dragon on a table gripping a crystal ball with his talons!

It really points out how destructive deer are. The overpopulation of deer is a real problem everywhere. I don't think wolves are the solution for very many locations. I sure don't want wolves running around here, but the deer population needs to be culled by humans. And no I am not a hunter so I don't want to do it personally.
