The oat, sometimes called the common oat, is a species of cereal grain grown for its seed, which is known by the same name. Oats are used for human consumption as oatmeal, including as steel cut oats or rolled oats. They appear to have been domesticated as a secondary crop as their seeds resembled those of other cereals closely enough for them to be included by early cultivators. Oats are a nutrient-rich food associated with lower blood cholesterol and reduced risk of human heart disease when consumed regularly. One of the most common uses of oats is as livestock feed; the crop can also be grown as groundcover and ploughed in as a green manure.
Onobrychis viciifolia, also known as O. sativa or common sainfoin has been an important forage legume in temperate regions until the 1950s. During the Green Revolution it was replaced by high yielding alfalfa and clover species. Due to its anthelmintic properties, common sainfoin is a natural alternative to drugs to control nematode parasitism in the guts of small ruminants. This is the main reason why O. viciifolia returned to the scientific agenda in recent years.
Avena is a genus of Eurasian and African plants in the grass family. Collectively known as the oats, they include some species which have been cultivated for thousands of years as a food source for humans and livestock. They are widespread throughout Europe, Asia and northwest Africa. Several species have become naturalized in many parts of the world, and are regarded as invasive weeds where they compete with crop production. All oats have edible seeds, though they are small and hard to harvest in most species.
Hypercalcemia, also spelled hypercalcaemia, is a high calcium (Ca2+) level in the blood serum. The normal range is 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), with levels greater than 2.6 mmol/L defined as hypercalcemia. Those with a mild increase that has developed slowly typically have no symptoms. In those with greater levels or rapid onset, symptoms may include abdominal pain, bone pain, confusion, depression, weakness, kidney stones or an abnormal heart rhythm including cardiac arrest.
Rhinanthus minor, known as yellow rattle, is a herbaceous wildflower in the genus Rhinanthus in the family Orobanchaceae. It has circumpolar distribution in Europe, Russia, western Asia, and northern North America. An annual plant, yellow rattle grows up to 10–50 centimetres (3.9–19.7 in) tall, with upright stems and opposite, simple leaves. The fruit is a dry capsule, with loose, rattling seeds.
Pennisetum is a widespread genus of plants in the grass family, native to tropical and warm temperate regions of the world. They are known commonly as fountaingrasses. Pennisetum is considered a synonym of Cenchrus in Kew's Plants of the World Online.
Deschampsia cespitosa, commonly known as tufted hairgrass or tussock grass, is a perennial tufted plant in the grass family Poaceae. Distribution of this species is widespread including the eastern and western coasts of North America, parts of South America, Eurasia and Australia.
St. Augustine grass, also known as buffalo turf in Australia and buffalo grass in South Africa, is a species of grass in the family Poaceae. It is a warm-season lawn grass that is popular for cultivation in tropical and subtropical regions. It is a medium- to high-maintenance grass that forms a thick, carpetlike sod, crowding out most weeds and other grasses.
Hordeum jubatum, with common names foxtail barley, bobtail barley, squirreltail barley, and intermediate barley, is a perennial plant species in the grass family Poaceae. It occurs wild mainly in northern North America and adjacent northeastern Siberia. However, as it escaped often from gardens it can be found worldwide in areas with temperate to warm climates, and is considered a weed in many countries. The species is a polyploid and originated via hybridization of an East Asian Hordeum species with a close but extinct relative of Californian H. brachyantherum. It is grown as an ornamental plant for its attractive inflorescences and when done flowering for its inflorescence.
Arrhenatherum elatius is a species of flowering plant in the grass family Poaceae, commonly known as false oat-grass, and also bulbous oat grass, tall oat-grass, tall meadow oat, onion couch and tuber oat-grass. It is native throughout Europe, and also western and southwestern Asia, and northwestern Africa. This tufted grass is sometimes used as an ornamental grass and is sometimes marketed as "cat grass".
Agropyron cristatum, the crested wheat grass, crested wheatgrass, fairway crested wheat grass, is a species in the family Poaceae. This plant is often used as forage and erosion control. It is well known as a widespread introduced species on the prairies of the United States and Canada.
Bovine leukemia virus (BLV) is a retrovirus which causes enzootic bovine leukosis in cattle. It is closely related to the human T‑lymphotropic virus type 1 (HTLV-I). BLV may integrate into the genomic DNA of B‑lymphocytes as a DNA intermediate, or exist as unintegrated circular or linear forms. Besides structural and enzymatic genes required for virion production, BLV expresses the Tax protein and microRNAs involved in cell proliferation and oncogenesis. In cattle, most infected animals are asymptomatic; leukemia is rare, but lymphoproliferation is more frequent (30%).
Lolium arundinaceum, tall fescue is a cool-season perennial C3 species of grass that is native to Europe. It occurs on woodland margins, in grassland and in coastal marshes. It is also an important forage grass with many cultivars that used in agriculture and is used as an ornamental grass in gardens, and sometimes as a phytoremediation plant.
Themeda is a genus of plants in the grass family native to Asia, Africa, Australia, and Papuasia. There are about 18 to 26 species, many of which are native to Southeast Asia.
Dactyloctenium aegyptium, or Egyptian crowfoot grass is a member of the family Poaceae native to Africa and Asia. The plant mostly grows in heavy soils at damp sites.
Helictochloa pratensis, known as meadow oat-grass, is a species of perennial flowering plant in the grass family Poaceae, found in temperate parts of Europe and Asia. Its culms are erect and 30–85 cm long; leaves are mostly basal. It is restricted to shallow, calcareous soils such as those formed on chalk and limestone substrates.
Trisetum spicatum is a species of grass known by the common name spike trisetum and spike false oat. It is native to North America, Eurasia, and South America. In North America it occurs throughout northern regions, including northern sections of the United States and most all of Canada, its range continuing to Greenland. It is widespread throughout the Canadian Arctic Islands. The grass occurs in a variety of Arctic and alpine habitat types, as well as many types of mountainous habitat in regions farther south. It is a perennial grass forming clumps of erect stems ranging in height from just a few centimeters to over one meter. The narrow leaves are mostly located around the bases of the densely clumped stems. The inflorescence is a narrow spike a few centimeters long or up to 30 to 50 centimeters in maximum length. The spikes are green to purple or brownish and shiny.
Elymus wawawaiensis is a species of grass known by the common name Snake River wheatgrass. It is native to western North America, where it occurs in the Pacific Northwest. It is native to eastern Washington and Oregon and parts of Idaho.
Eragrostis pilosa is a species of grass in the family Poaceae. It is native to Eurasia and Africa. It may or may not be native to North America. It is widely introduced, and it is a common weed in many areas.
Lutzomyia shannoni is a species of fly in the subfamily Phlebotominae, the phlebotomine sand flies. It is native to the Americas from the southeastern United States to northern Argentina. It has a disjunct distribution, and is only found in regions with suitable climates, habitat types, and host animals. It is well known as a vector of the vesicular stomatitis virus, which causes the disease vesicular stomatitis in animals, particularly livestock.
