Disappearance of a keystone species often results in a complete rearrangement of the food web. This is referred to by the term trophic cascade. If the keystone species is at the top of the food chain, the disappearance of this top predator can cause a top-down trophic cascade. If the keystone species is at the base of the food chain, the ...

A trophic cascade affected the entire food web in Yellowstone, causing some organisms to experience decreases, and others to grow rapidly. Biodiversity increased when the wolves disappeared and more species were able to flourish without the wolves. A trophic cascade irreversibly ruined the ecosystem in Yellowstone--destroying biodiversity forever.

Trophic transfer efficiency (TTE) is usually calculated as the ratio of production rates between two consecutive trophic levels. Although seemingly simple, TTE estimates from lakes are rare. In our review, we explore the processes and structures that must be understood for a proper lake TTE estimate. We briefly discuss measurements of …
