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 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 ...
The worms were originally transferred through the horticultural trade, probably in the soil bulbs of European plants carried to the Americas. Some earthworms have been brought over to be used as bait for fishing and escaped or got released. For example, at least one species of earthworm was introduced in Alaska as bait for anglers. [19]
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.
The Lumbricidae are a family of earthworms.About 33 lumbricid species have become naturalized around the world, [1] but the bulk of the species are in the Holarctic region: from Canada (e.g. Bimastos lawrenceae on Vancouver Island) and the United States (e.g. Eisenoides carolinensis, Eisenoides lonnbergi and most Bimastos spp.) and throughout Eurasia to Japan (e.g. Eisenia japonica, E. koreana ...
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.
A graminivore is a herbivorous animal that feeds primarily on grass, [1] specifically "true" grasses, plants of the family Poaceae (also known as Graminae). Graminivory is a form of grazing . These herbivorous animals have digestive systems that are adapted to digest large amounts of cellulose , which is abundant in fibrous plant matter and ...
