The pig-tailed langur, monotypic in genus Simias, is a large Old World monkey, endemic to several small islands off the coast of Sumatra in Indonesia. Its face is black, its fur is blackish-brown and it has a relatively short tail. It is a diurnal species, feeding in small groups in the rainforest canopy on leaves, and to a lesser extent, fruit and berries. Little is known of its natural history, but it is heavily hunted, its populations have been declining rapidly and the International Union for Conservation of Nature has assessed its conservation status as being "critically endangered". It has been included on a list of the World's 25 Most Endangered Primates.
Parmelia is a genus of medium to large foliose lichens. It has a global distribution, extending from the Arctic to the Antarctic continent but concentrated in temperate regions. There are about 40 species in Parmelia. In recent decades, the once large genus Parmelia has been divided into a number of smaller genera according to thallus morphology and phylogenetic relatedness.
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.
Erioderma pedicellatum is a medium-sized, foliose lichen in the family Pannariaceae, commonly called the boreal felt lichen. It grows on trees in damp boreal forests along the Atlantic coast in Canada, as well as in southcentral Alaska and in the Kamchatka Peninsula.
An IUCN Red List Critically Endangered (CR) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of 2021, of the 120,372 species currently tracked by the IUCN, there are 8,404 species that are considered to be Critically Endangered.
Villa's gray shrew is a shrew native to northeastern Mexico, where it is called musaraña.
Raorchestes shillongensis is a species of frog in the family Rhacophoridae. It is endemic to Greater Shillong in North East India. It is known from the Khasi Hills in the region of Shillong, Meghalaya in north-eastern India. It has been categorized as Critically Endangered because its extent of occurrence is less than 100 km2, its distribution is severely fragmented, there is continuing decline in the extent and quality of its habitat, and in the number of mature individuals in and around Shillong, in Meghalaya, northeastern India.
The fiery minivet is a species of bird in the family Campephagidae. Its range includes Thailand, Malaysia, Indonesia and the Philippines. Its natural habitats are broadleaf, secondary and coastal forests. It is threatened by forest clearance and has been assessed as near-threatened by the International Union for Conservation of Nature (IUCN).
The black dorcopsis or black forest wallaby is a species of marsupial in the family Macropodidae. It is endemic to an island at the eastern end of New Guinea where its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss and hunting, its population is declining and the IUCN lists it as being "Critically endangered".
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.
Calicium is a genus of leprose lichen lichens. It is in the family Caliciaceae.
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 36 genera and about 600 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
The Philippine collared dove is a species of bird in the family Columbidae. It was formerly considered a subspecies of the island collared dove.
Physcia caesia, known colloquially as blue-gray rosette lichen and powder-back lichen, is a species of foliose lichenized fungus. First described by Georg Franz Hoffmann in 1784, it is common across much of Europe, North America and New Zealand, and more patchily distributed in South America, Asia, Australia and Antarctica. There are 2 subspecies: P. c. caesia and P. c. ventosa, as well as a number of distinct forms and varieties. Molecular studies suggest that the species as currently defined may be polyphyletic. It is typically pale gray shading to darker gray in the center, and grows in a small rosette, usually some 2–3 cm (0.79–1.18 in) across at maturity. It only rarely has apothecia, instead reproducing most often vegetatively via soredia, which are piled in round blue-gray mounds across the thallus's upper surface. It grows most often on rock—principally calcareous, but also basaltic and siliceous—and also occurs on bone, bark and soil. It is nitrophilic and is particularly common on substrates where birds perch.
Calicium chlorosporum is a crustose lichen that is found growing on trees throughout much of the world.
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.
Punctelia caseana is a species of foliose lichen in the family Parmeliaceae. Its range covers eastern North America, extending south to central and northern Mexico, where it grows on the bark of many species of hardwood and conifer trees.
Anzia centrifuga is a species of foliose lichen in the family Parmeliaceae. It is found only on one volcano on Porto Santo in the Madeira Archipelago, where it grows on rocks.
Candelaria concolor, commonly known as the candleflame lichen or the lemon lichen, is an ascomycete of the genus Candelaria. It is a small foliose lichen dispersed globally.
Calicium pinicola is a species of lignicolous (wood-dwelling), crustose lichen in the family Caliciaceae. It is widely distributed in Europe, and also occurs in the United States.
