Where does the fox live in the food web?
BOB: An essential missing part of Yellowstone was the wolf that was last taken out or extirpated or locally made extinct in the 1920’s. Sixty years went by and a lot of effort went into bringing back this last missing piece, the wolf. Based on studies done before wolves were reintroduced and after and continuing, we can really take advantage of this ecosystem scale experiment. In 1995 and 1996, after twenty years of effort by a lot of organizations, wolves captured in social groups in Canada were transported down, acclimated in pens, and released. Teams of researchers were ready to find out what was going to happen. Interviewer: What did you hope to learn: BOB: A question that scientists often try to answer to understand about ecosystems is this. Are the things at the top of the food chain more important in structuring communities? Or is it things at the bottom of the food chain, or bottom-up effect? This allowed us an experiment from the top down. That’s much easier to do than, for ex
