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'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").
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.
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
The state Department of Fish and Wildlife hopes to track the latest wolverine by collecting hair and scat and analyzing more photos and video from those rare Californians who have seen the mammals ...
Humans sometimes live by hunting other animals for food and materials such as fur, sinew, and bone, as in this walrus hunt in the Arctic, but humans' status as apex predators is debated. Ecologists have debated whether humans are apex predators. For instance, Sylvain Bonhommeau and colleagues argued in 2013 that across the global food web, a ...
