I'm doing a paper for Biology II on predation. It's an explanatory paper focusing on what happens when predation goes wrong, i.e. over population resulting in famine, etc. So I need a visual example that isn't just your standard cheetah chasing down an antelope. Any ideas? Specific graph or photo links are what I'm looking for.
