Chives, scientific name Allium schoenoprasum, is a species of flowering plant in the family Amaryllidaceae that produces edible leaves and flowers.
Bracken (Pteridium) is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells. Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world.
Cheilanthes, commonly known as lip ferns, is a genus of about 180 species of rock-dwelling ferns with a cosmopolitan distribution in warm, dry, rocky regions, often growing in small crevices high up on cliffs. Most are small, sturdy and evergreen. The leaves, often densely covered in trichomes, spring directly from the rootstocks. Many of them are desert ferns, curling up during dry times and reviving with the coming of moisture. At the ends of veins sporangia, or spore-bearing structures, are protected by leaf margins, which curl over them.
Sodium fluoroacetate, also known as compound 1080, is an organofluorine chemical compound with the chemical formula FCH2CO2Na. It is the sodium salt of fluoroacetic acid. It contains sodium cations Na+ and fluoroacetate anions FCH2CO−2. This colourless salt has a taste similar to that of table salt and is used as a rodenticide.
Polioencephalomalacia (PEM), also referred to as cerebrocortical necrosis (CCN), is a neurological disease seen in ruminants that is caused by multiple factors, one of which is thiamine depletion in the body. Thiamine is a key chemical in glucose metabolism that, when deficient, is most threatening to neurological activity. In addition to altered thiamine status, an association with high sulfur intake has been observed as a potential cause of PEM. PEM may also be caused by other toxic or metabolic diseases such as: acute lead poisoning or salt poisoning. Cattle, sheep, goat, and other ruminants that are diagnosed with PEM or pre-PEM suffer opisthotonus, cortical blindness, disoriented movement, and eventually fatality, if left untreated. Current data shows that the onset of PEM can range from birth to late adulthood.
Asparagus setaceus, commonly known as common asparagus fern, asparagus grass, lace fern, climbing asparagus, or ferny asparagus, is a climbing plant in the genus Asparagus. Despite its common name, the plant is not a true fern, but has leaves that resemble one.
Natural Bridge State Park is a 530-acre (214 ha) state park of Wisconsin, United States, featuring Wisconsin's largest natural arch. Directly beneath the arch is the Raddatz Rockshelter, a rock shelter once used by Paleo-Indians and now listed on the National Register of Historic Places. The park is located southwest of Baraboo between the unincorporated communities of Leland and Denzer, in the town of Honey Creek.
Facial eczema is a mycotoxic disease that affects the liver of several animals, mainly sheep and cattle, but can also infect other ungulates. It is caused by ingesting sporidesmins released by the fungus Pithomyces chartarum. Its visible symptoms are characterized by red skin that turns black and crusty before peeling off, as well as inflammation that can cause swelling of the udder, teats, ears and face. The disease is not always visible. Other symptoms include weight loss, weakness and death.
The health of domestic cats is a well studied area in veterinary medicine.
Myriopteris gracilis, formerly known as Cheilanthes feei, is a species of lip fern known by the common name slender lip fern or Fee's lip fern.
Myriopteris intertexta, formerly Cheilanthes intertexta, is a species of lip fern known by the common name coastal lip fern. It is native to montane California and western Nevada, Oregon east of the Cascades, and with a disjunct population in central Utah. It grows in dry rocky habitats in sun, typically in rock cracks with little or no soil.
Conium maculatum, known as hemlock, or poison hemlock is a highly poisonous flowering plant in the carrot family Apiaceae, native to Europe and North Africa. It is herbaceous without woody parts and has a biennial lifecycle. A hardy plant capable of living in a variety of environments, hemlock is widely naturalised in locations outside its native range, such as parts of Australia, West Asia, and North and South America, to which it has been introduced. It is capable of spreading and thereby becoming an invasive weed.
Ptaquiloside is a norsesquiterpene glucoside produced by bracken ferns during metabolism. It is identified to be the main carcinogen of the ferns and to be responsible for their biological effects, such as haemorrhagic disease and bright blindness in livestock and oesophageal, gastric cancer in humans. Ptaquiloside has an unstable chemical structure and acts as a DNA alkylating agent under physiological conditions. It was first isolated and characterized by Yamada and co-workers in 1983.
CAB Direct is a source of references for the applied life sciences It incorporates two bibliographic databases: CAB Abstracts and Global Health. CAB Direct is an access point for multiple bibliographic databases produced by CABI. This database contains over 11 million bibliographic records, which includes 746,000 full text articles. It also includes noteworthy literature reviews. News articles and reports are also part of this combined database. CAB Direct has now migrated to CABI's new platform CABI Digital Library - the new home of CABI's research content.
Cheilanthes distans is a species of lip fern known by the common name bristly cloak fern. It has a woolly appearance with small white hairs on the top side of the fronds, and a rusty brown underneath.
Cheilanthes austrotenuifolia is a species of Australian rock fern from the family Pteridaceae. Once a common understory plant along streams in moist areas of Southern Australia, Cheilianthes austrotenuifolia is still quite widespread in remnant bush-land, such as areas of the Adelaide Hills, although it has been affected significantly by land clearance and competition from invasive species.
Oxytropis sericea is a species of flowering plant in the legume family known by the common names white locoweed, white point-vetch, whitepoint crazyweed, and silky crazyweed. It is native to western North America from Yukon and British Columbia south through the Pacific Northwest, the Rocky Mountains, and the Great Plains.
Cheilanthoideae is one of the five subfamilies of the fern family Pteridaceae. The subfamily is understood to be monophyletic, but some of the genera as currently defined are not. Most species are xeric-adapted, and the subfamily is most diverse in dry areas.
Myriopteris aemula, the Texas lip fern or rival lip fern, is a moderately-sized fern of Texas and Mexico, a member of the family Pteridaceae. Unlike many members of its genus, its leaves have a few hairs on upper and lower surfaces, or lack them entirely. One of the cheilanthoid ferns, it was usually classified in the genus Cheilanthes as Cheilanthes aemula until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows on limestone rock.
