A lynx is any of the four species within the medium-sized wild cat genus Lynx. The name lynx originated in Middle English via Latin from the Greek word λύγξ, derived from the Indo-European root leuk- in reference to the luminescence of its reflective eyes.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
The common rock thrush, also known as rufous-tailed rock thrush or simply rock thrush, is a chat belonging to the family Muscicapidae. It was formerly placed in the family Turdidae. The scientific name is from Latin. Monticola is from mons, montis "mountain", and colere, "to dwell", and saxatilis means "rock-frequenting", from saxum, "stone".
The Endangered Species Act of 1973 is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation". The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed. It therefore "protect[s] species and the ecosystems upon which they depend" through different mechanisms. For example, section 4 requires the agencies overseeing the Act to designate imperiled species as threatened or endangered. Section 9 prohibits unlawful ‘take,’ of such species, which means to "harass, harm, hunt..." Section 7 directs federal agencies to use their authorities to help conserve listed species. The Act also serves as the enacting legislation to carry out the provisions outlined in The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The Supreme Court found that "the plain intent of Congress in enacting" the ESA "was to halt and reverse the trend toward species extinction, whatever the cost." The Act is administered by two federal agencies, the United States Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS). FWS and NMFS have been delegated by the Act with the authority to promulgate any rules and guidelines within the Code of Federal Regulations (CFR) to implement its provisions.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
Wildcrafting is the practice of harvesting plants from their natural, or 'wild' habitat, primarily for food or medicinal purposes. It applies to uncultivated plants wherever they may be found, and is not necessarily limited to wilderness areas. Ethical considerations are often involved, such as protecting endangered species, potential for depletion of commonly held resources, and in the context of private property, preventing theft of valuable plants, for example, ginseng.
Desmoulin's whorl snail is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusc or micromollusc in the family Vertiginidae, the whorl snails.
The depressed river mussel or compressed river mussel, Pseudanodonta complanata, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. The species name comes from the flattened shape of its shell.
The swan mussel, Anodonta cygnea, is a large species of freshwater mussel, an aquatic bivalve mollusc in the family Unionidae, the river mussels.
Vertigo angustior, the narrow-mouthed whorl snail, is a species of minute land snail, a terrestrial pulmonate gastropod mollusk or micromollusk in the family Vertiginidae, the whorl snails.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Pine Hill Ecological Reserve is a nature reserve of 403 acres (1.63 km2) located due east of Folsom Lake in the Sierra Nevada foothills, in El Dorado County, California. The reserve was established in 1979, and is managed by the California Department of Fish and Game.
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature that is threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
Cheilotoma fulvicollis is a species of leaf beetles in the subfamily Cryptocephalinae that is endemic to Syria.
Cheilotoma is a genus of beetles in the subfamily Cryptocephalinae of the leaf beetles family.
Cheilotoma beldei is a species of leaf beetles from the subfamily of Cryptocephalinae that can be found in Jordan and Turkey. Cheilotoma beldei has the greatest resemblance to Cheilotoma musciformis.
Cheilotoma voriseki is a species of leaf beetles from the subfamily Cryptocephalinae. It can be found in Turkey on Mount Nemrut in Adıyaman.
Cheilotoma erythrostoma is a species of leaf beetles from the subfamily Cryptocephalinae. It can be found in Bulgaria, Italy, Romania, in Crimea, in the south of Russia and the Caucasus. It can also be found in Czech Republic and Slovakia.
Hypnea is a genus of red algae, and a well known carrageenophyte.
Endangered species as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
