The wolverine's questionable reputation as an insatiable glutton (reflected in its Latin genus name Gulo, meaning "glutton") may be in part due to a false etymology.The less common name for the animal in Norwegian, fjellfross, meaning "mountain cat", is thought to have worked its way into German as Vielfraß, [5] which means "glutton" (literally "devours much").
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
The wolverine is an effective scavenger, capable of cracking heavy bones and shows the same adaptations in the jaw as the hyenas do. The sagittal crest projects well above the area of attachment of the neck muscles, and in a large animal it extends back far behind the level of the condyles to provide attachments for the relatively enormous ...
But the wolverine listing makes exceptions on an interim basis for mortality caused by "incidental trapping," research activities or forest management designed to reduce wildfire risks.

Wolverines were first petitioned to be listed under the Endangered Species Act in 1995. The U.S. Fish and Wildlife Service proposed to list the wolverine as a threatened species in 2013.
The observed values of connectance in empirical food webs appear to be constrained by the variability of the physical environment, [4] by habitat type, [5] which will reflect on an organism's diet breadth driven by optimal foraging behaviour. This ultimately links the structure of these ecological networks to the behaviour of individual organisms.
A food web of The Secaucus High School Marsh exemplifies the benefits of grouping as the relationships between nodes are far easier to analyze with well-made communities. While the first graphic is hard to visualize, the second provides a better view of the pockets of highly connected feeding relationships that would be expected in a food web.
