''Ilex cookii'' (Cook's holly or ''te'') is a species of plant in the family Aquifoliaceae. It is endemic to Puerto Rico. It is threatened by habitat loss. It is a federally listed endangered species of the United States. Conservation This tree is only known from a single specimen and a few seedlings in the cloud forests on Cerro de Punta and Monte Jayuya, both at Toro Negro State Forest Toro Negro State Forest (Spanish: ''Bosque Estatal de Toro Negro'') is one of the 21 forests that make up the public forests system in Puerto Rico. It is also Puerto Rico's highest cloud forest. It is in the Cordillera Central, Puerto Rico, Cord ... in Puerto Rico. Other specimens were probably destroyed when a communications tower was installed on Cerro de Punta. ''I. cookii'' was listed as a federally endangered species in 1987.

Early life Britton was born on the 15 of January 1859 at New Dorp, Staten Island, New Dorp, Staten Island, New York, Richmond County, New York (state) to Jasper Alexander Hamilton Britton and Harriet Lord Turner. His parents wanted him to study religion, but he was attracted to nature study at an early age. He was a graduate of the School of Engineering and Applied Science (Columbia University), Columbia University School of Mines and afterwards taught geology and botany at Columbia University. He joined the Torrey Botanical Society, Torrey Botanical Club soon after graduation and was a member his entire life. Britton was an elected member of the United States National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society. He married Elizabeth Gertrude Britton, Elizabet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...

Endemic Flora Of Puerto Rico
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Ilex
''Ilex'' () or holly is a genus of over 570 species of flowering plants in the 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 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 habitats. It occurs from sea level to more than with high mountain species. It is a genus of small, evergreen trees with smooth, glabrous, or pubescent branchlets. The plants are generally slow-growing with some species growing to tall. The type ...

Convention For The Protection And Development Of The Marine Environment Of The Wider Caribbean Region
The Convention for the Protection and Development of the Marine Environment of the Wider Caribbean Region, commonly called the Cartagena Convention, is an international agreement for the protection of the Caribbean Sea, the Gulf of Mexico and a portion of the adjacent Atlantic Ocean. It was adopted on 24 March 1983, entered into force on 11 October 1986 subsequent to its ratification by Antigua and Barbuda, the ninth party to do so, and has been ratified by 26 states. It has been amended by three major protocols: the Protocol Concerning Co-operation in Combating Oil Spills in the Wider Caribbean Region (Oil Spills Protocol), the Protocol Concerning Specially Protected Areas and Wildlife to the Convention for the Protection and Development of the Marine Environment of the Wider Caribbean Region (SPAW Protocol) and the Protocol Concerning Pollution from Land-Based Sources and Activities to the Convention for the Protection and Development of the Marine Environment of the Wider Car ...

Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Cloud Forest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest, is a generally tropical or subtropical, evergreen, Montane forest, montane, Tropical and subtropical moist broadleaf forests, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the ''International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the mountain pass, saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity-rich ecosystems in the world, with a large number of species directly or indirectly depending on them. Other moss forests include black spruce/feathermoss Climax community, climax forest, with a moderately dense canopy and a forest fl ...
