This isn't hands-on, but Jean Craighead George has written several "ecological mysteries" that I absolutely loved as a kid. If I remember correctly, two involve trophic relationships -- _Hook a Fish, Catch a Mountain_ (republished as _The Case of the Missing Cutthroats_) and _Who Really Killed Cock Robin?_. Books like these do a great job of linking what we actually see in nature (an unusually large trout, a dead robin) with invisible ecological relationships.
