Xerophyllum tenax is a North American species of plants in the corn lily family. [1] [2] It is known by several common names, including bear grass, soap grass, quip-quip, and Indian basket grass. [3] The name "beargrass" is thought to come from its connection to both the plant's habitat and its relationship with bears.
Earthworms are shifting their ranges northwards into forests between 45° and 69° latitude in North America that have lacked native earthworms since the last ice age. [3] Of the 182 taxa of earthworms found in the United States and Canada, 60 (33%) are introduced species, these earthworm species are primarily from Europe and Asia.
Earthworms use, in addition to the digestive proteins, a class of surface active compounds called drilodefensins, which help digest plant material. [29] Instead of being coiled like a mammalian intestine, in the earthworm's intestine a large mid-dorsal, tongue-like fold is present, called a typhlosole , with many folds running along its length ...
In Britain, it is primarily called the common earthworm or lob worm (though the name is also applied to a marine polychaete). In North America , the term nightcrawler (or vitalis ) is also used, and more specifically Canadian nightcrawler , referring to the fact that the large majority of these worms sold commercially (usually as fishing bait ...
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Wildlife experts used jelly doughnuts and sardines to lure the bear out of the tree.
Cubs can climb a tree when threatened, so there is no need for a mother bear to attack. Give the bears plenty of space; changing routes is always a good option as well. 2.
Approximately 182 earthworm taxa in twelve families are reported from the United States and Canada, of which sixty (about 33%) are introduced. [4] Only two genera of lumbricid earthworms are indigenous to North America while introduced genera have spread to areas without any native species, especially in the north where forest ecosystems rely on a large amount of undecayed leaf matter.
