IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, 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 aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Townshend Stith Brandegee
Townshend Stith Brandegee (February 16, 1843 – April 7, 1925) was an American botanist. He was an authority on the flora of Baja California and the Channel Islands of California, Channel Islands of California. Early life Brandegee was born on February 16, 1843, in Berlin, Connecticut. From 1862 to 1864 he served in the Connecticut Artillery and later decided to become an engineer. He got his degree in engineering from Sheffield Scientific School but then pursued botany after he participated at some classes with Daniel Cady Eaton in Yale University. When he graduated from there, he became a county surveyor and city engineer at Canon City, Colorado where in free time he also collected certain species of plants. He was accustomed with John H. Redfield and Asa Gray the later of which suggested him to join Ferdinand V. Hayden's expedition to southwest Colorado and Utah where he will use his surveyor skills as well as botanical. He was hired as a railroad surveyor in both Arkansas and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilex
''Ilex'' (), or holly, is a genus of over 570 species of flowering plants in the family (biology), family Aquifoliaceae, and the only living genus in that family. ''Ilex'' has the most species of any woody dioecious angiosperm genus. The species are evergreen or deciduous trees, shrubs, and climbers from tropics to temperate zones worldwide. The type species is ''Ilex aquifolium'', the common European holly used in Christmas decorations and cards. Description The genus ''Ilex'' is divided into three subgenera: *''Ilex'' subg. ''Byronia'', with the type species ''Ilex polypyrena'' *''Ilex'' subg. ''Prinos'', with 12 species *''Ilex'' subg. ''Ilex'', with the rest of the species The genus is widespread throughout the temperate and subtropical regions of the world. It includes species of trees, shrubs, and climbers, with evergreen or deciduous foliage and inconspicuous flowers. Its range was more extended in the Tertiary period and many species are adapted to laurel forest habi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socorro Island
Socorro Island ( es, Isla Socorro) is a small volcanic island in the Revillagigedo Islands, a Mexican possession lying off the country's western coast. The size is 16.5 by 11.5 km (10.25 by 7.15 miles), with an area of . It is the largest of the four islands of the Revillagigedo Archipelago. The last eruption was in 1993. Geology The island rises abruptly from the sea to in elevation at its summit. Socorro Island is the emerged summit of a massive, predominately submarine shield volcano. The island is part of the northern Mathematicians Ridge, a mid-ocean ridge that became largely inactive 3.5 million years ago when activity moved to the East Pacific Rise. All four islands along with the many seamounts on the ridge are post-abandonment alkaline volcanoes. Socorro Island is unusual in that it is the only dominantly silicic peralkaline volcanic island in the Pacific Ocean. It most recently erupted in late Januaryearly February, 1993, which was a submarine flank eruption ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revillagigedo Islands
The Revillagigedo Islands ( es, Islas Revillagigedo, ) or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately from Socorro Island south and southwest of Cabo San Lucas, the southern tip of the Baja California Peninsula, and west of Manzanillo, Colima, Manzanillo. Historically linked to the Mexican state of Colima, to which they were granted in 1861 to establish a penal colony, the islands are under Mexican federal property and jurisdiction. In July 2016, the Revillagigedo Archipelago was inscribed as a UNESCO World Heritage Site, and in November 2017 they were declared to be a marine reserve and a List of national parks of Mexico, national park of Mexico. Some of the volcanoes are active, with the last eruption of Volcán Bárcena in 1953, and Socorro (volcano), Socorro in 1993. Travelling to the islands from their nearest land point takes approximately 26 to 30 hours, as they are typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guettarda Insularis
''Guettarda'' is a plant genus in the family Rubiaceae. Most of these plants are known by the common name velvetseed. Estimates of the number of species range from about 50 Anthony J.

Sideroxylon Socorrense
''Sideroxylon socorrense'' is a plant species in the family Sapotaceae. It is endemic to Mexico, occurring only on Socorro in the Revillagigedo Islands. On its island home, this small tree grows in habitat that is at least seasonally humid. This restricts it mainly to a belt of woodland between 650 and 900 m above mean sea level, except on the northern side where wetter conditions predominate. It is classified as Vulnerable by the IUCN due to the adverse effects of introduced sheep grazing and the twice-yearly swarming of the locust ''Schistocerca piceifrons'', a non-native pest that has become established on Socorro more recently. The fruits of this plant are among the favorite foods of the nearly-extinct Socorro mockingbird (''Mimus graysoni'') and the Socorro dove (''Zenaida graysoni'') which presently only survives in captivity.BLI (2007b) Similar as in other ''Sideroxylon ''Sideroxylon'' is a genus of trees in the family Sapotaceae described as a genus by Linnaeus in ...

Psidium Oligospermum
''Psidium oligospermum'', the Galápagos guava or guayabillo, is a small tree or shrub native to the tropical Americas, ranging from Mexico through the Revillagigedo Islands, Central America, Cuba, Puerto Rico, the Windward Islands, the Galápagos Islands, and South America to central Brazil and northwestern Argentina. Description ''Psidium oligospermum'' is either a small tree or shrub that ranges up to in height and up to in diameter, with smooth, pinkish-grey bark. It has wide-spreading branches with dotted grey branchlets with reddish to white or yellowish "trichomes" or hairs. The branchlets tend to become more smooth at the edges and the bark more stringy, and the terminal branchlets and leaves are sometimes covered with a scurfy reddish bloom.Duncan M. Porter (1968) ''Annals of the Missouri Botanical Garden: Psidium (Myrtaceae) in the Galapagos Islands'' Vol. 55, No. 3, p. 368-371 Its leaves are opposite and elliptic to ovate, with the tips of the leaves being acute ...

Trees Of Mexican Pacific Islands
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1910
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...
