In this book, a multidisciplinary research team tests this idea by manipulating whole lakes experimentally, and coordinating this with palaeolimnological studies, simulation modelling, and small-scale enclosure. A series of changes in the population sizes of organisms at different trophic levels in a food chain, occurring when predators at high trophic levels indirectly promote populations of organisms at low trophic levels by keeping species at intermediate trophic levels in check.

Trophic cascades may become apparent when a top predator is eliminated.

At their most fundamental level, trophic cascades are powerful stories about ecosystem processes—of predators and their prey, of what it takes to survive in a landscape, of the flow of nutrients.

The Wolf's Tooth is the first book to focus on the vital connection between trophic cascades and restoring biodiversity and habitats, and to do so. Trophic cascades in ecological communities are defined as the vertical propagation of indirect mutualism between non-adjacent trophic levels in a food chain or.

Using the glaucous winged gull or the bald eagle as an example, explain how the diet of each is.

In this book, a multidisciplinary research team tests this idea by manipulating whole lakes experimentally, and coordinating this with paleolimnological studies, simulation modeling, and small-scale enclosure experiments.

Contributors describe consequences of predator-prey interactions, behavioral responses of fishes, diel vertical migration of zooplankton, plankton. A notable example of this top-down ecological interaction was observed in Yellowstone National Park in the western United States. In the s, the local extinction of the park's population of gray wolves (Canis lupus) through hunting caused an increase in the population of elk (Cervus elaphus), thereby leading to an overwhelming drop in the abundance of numerous plants.

This is the case in the piper plant experiment. When only three organisms were in the food chain and ants were at the top, there was a positive effect on the amount of leaf matter on the plant.
