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. [4]
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 ...
Yellowstone wolf pack territories in 2011. Wolf population declines, when they occur, result from "intraspecific strife," food stress, mange, canine distemper, legal hunting of wolves in areas outside the park (for sport or for livestock protection) and in one case in 2009, lethal removal by park officials of a human-habituated wolf.

In late 2008, Wolf 302M decided to disperse from the pack with a group of five younger males (his nephews and sons), drifting through rival pack territories until joining four females of the Agate Creek Pack, one adult, one young adult, and two yearlings, to form the Blacktail Plateau pack in late 2008, which 302M began leading.
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.
English: This diagram illustrates trophic cascade in an environment. The cascade to the left 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.

Wolf OR-7 became the first wolf west of the Cascades in Oregon since the last bounty was claimed in 1947. [139] Oregon's wolf population increased to 77 wolves in 15 packs with 8 breeding pairs as of the end of 2015. [125] As a result, Oregon Department of Fish and Wildlife proposed to delist wolves from their protected species list. [140]
