English: This diagram illustrates trophic cascade in an environment. The cascade to the right shows a healthy ecosystem with a top predator, a primary consumer and a primary producer. The wolf at the top of the cascade is the top predator of the environment. The top predator makes sure that the deer and elk populations stay at healthy levels.
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate ...

Gray wolf in YellowStone National Park. A clear example of humans ecosynthesiszing would be through the introduction of a species to cause a trophic cascade, which is the result of indirect effects between nonadjacent trophic levels in a food chain or food web, such as the top predator in a food chain and a plant.

Meanwhile, wolf packs often claim kills made by cougars, which has driven that species back out of valley hunting grounds to their more traditional mountainside territory. [45] The top-down effect of the reintroduction of an apex predator like the wolf on other flora and fauna in an ecosystem is an example of a trophic cascade.
This is a strong example of the importance of the maintenance of the trophic cascade and suggests that top-down control is the primary regulatory factor in this system. James Estes and John Palmisano did similar experiments with otters, sea urchins, and kelp, where otter presence increased kelp presence in a trophic cascade . [ 9 ]
Recently another subspecies, the British Columbia wolf (Canis lupus columbianus), has established itself in the Cascade mountain wolf's past territory by following the Cascade Range through Washington and is now west of the Cascade Crest, [8] expanding across Oregon, [9] and into northern California to Lassen Peak, where in 2019 the Lassen pack produced 3 pups.
The Armijska Ratna Komanda D-0 (full civil designation in Serbo-Croatian: Vojni objekat Armijska Ratna Komanda ARK D-0, Армијска Ратна Команда, lit. 'Army War Command'), also known as the Ark, ARK/D-0, Atomska Ratna Komanda, and nicknamed Tito's bunker, [3] is a Cold War-era nuclear bunker and military command centre located near the town of Konjic [4] in Bosnia and ...
