Iryanthera Megistocarpa
''Iryanthera megistocarpa'' is a species of plant in the family Myristicaceae. It is endemic to Panama. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

Alwyn Howard Gentry
Alwyn Howard Gentry (January 6, 1945 – August 3, 1993) was an American botanist and plant collector, who made major contributions to the understanding of the vegetation of tropical forests. Education Gentry was born on January 6, 1945, in Clay Center, Kansas, and received his schooling at the Clay Center Community High School, from which he graduated in 1963. He graduated from Kansas State University in 1967 with a B.A. in physical science and a B.S. in botany and zoology. He earned his master's degree in 1969 at the University of Wisconsin–Madison as a student of botanist Hugh Iltis, with a thesis on the genus ''Tabebuia'' (Bignoniaceae) of Central America, a subject which he continued to study at Washington University in St. Louis, Missouri, from which he received his doctorate in 1972, with a Ph.D. thesis entitled ''An Eco-evolutionary Study of the Bignoniaceae of South Central America''. Career Gentry spent his entire working career at the Missouri Botanical Garden, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
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 lost the ...

Myristicaceae
The Myristicaceae are a family of flowering plants native to Africa, Asia, Pacific islands, and the Americas and has been recognized by most taxonomists. It is sometimes called the "nutmeg family", after its most famous member, ''Myristica fragrans'', the source of the spices nutmeg and mace. The best known genera are ''Myristica'' in Asia and ''Virola'' in the Neotropics. The family consists of about 21 genera with about 520 species of trees, shrubs and rarely lianas ('' Pycnanthus'') found in tropical forests around the world. Most of the species are large trees that are valued in the timber industry. Description They are typically trees with reddish sap and distinctive pagoda-like growth (known as myristicaceous branching) in which horizontal branching only occurs at certain nodes along the main axis of the trunk, each node separated by a large gap where no branching occurs. All genera are dioecious, except ''Endocomia'' and some ''Iryanthera''. The inner bark is usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama
Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people. Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of En ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Flora Of Panama
Panama is a country located in Central America, bordering both the Caribbean Sea and the Pacific Ocean, between Colombia and Costa Rica. Panama is located on the narrow and low Isthmus of Panama. This S-shaped isthmus is situated between 7° and 10° north latitude and 77° and 83° west longitude. Panama encompasses approximately . It is long, and between wide. Geology The geology of Panama is extremely complicated. The land was formed by interactions of several tectonic plates over the past 10 million years. Elevation The dominant feature of Panama's landform is the central spine of mountains and hills that forms the continental divide. The divide does not form part of the great mountain chains of North America, and only near the Colombian border are there highlands related to the Andes, Andean system of South America. The spine that forms the divide is the highly eroded arch of an uplift from the sea bottom, in which peaks were formed by volcanic intrusions. The we ...
