Blepharidium
''Blepharidium'' is a monotypic genus of flowering plants in the family Rubiaceae. The genus contains only one species, viz. ''Blepharidium guatemalense'', which is native to Guatemala, Honduras and southern Mexico (Chiapas, Campeche, Tabasco). Older works might mention two species (viz. ''B. guatemalense'' and ''B. mexicanum''). Systematics ''Blepharidium'' was named by Paul Standley in 1918. The name is derived from the Ancient Greek words ''blepharitis'' or ''blepharidos'', meaning "on an eyelid". The similar term, ''blepharis'' means "an eyelash". A cladistic analysis of morphological characters found ''Blepharidium'' to be closely related to ''Cosmibuena'', ''Balmea'', and '' Hillia'', but a molecular phylogenetic study Study or studies may refer to: General * Education **Higher education * Clinical trial * Experiment * Observational study * Research * Study skills, abilities and approaches applied to learning Other * Study (art), a drawing or series of drawi ...

Paul Carpenter Standley
Paul Carpenter Standley (March 21, 1884 – June 2, 1963) was an American botanist known for his work on neotropical plants. __TOC__ Standley was born on March 21, 1884 in Avalon, Missouri. He attended Drury College in Springfield, Missouri and New Mexico State College, where he received a bachelor's degree in 1907, and received a master's degree from New Mexico State College in 1908. He remained at New Mexico State College as an assistant from 1908–1909. He was the Assistant Curator of the Division of Plants at the United States National Museum from 1909 to 1922. In spring, 1928, he took a position at the Field Museum of Natural History in Chicago, where worked until 1950. While at the Field Museum he did fieldwork in Guatemala between 1938 and 1941. After his retirement in 1950, he moved to the '' Escuela Agricola Panamericana,'' where he worked in the library and herbarium and did field work until 1956, when he stopped doing botanical work. In 1957 he moved to Tegucigalp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Morphology
Phytomorphology is the study of the morphology (biology), physical form and external structure of plants.Raven, P. H., R. F. Evert, & S. E. Eichhorn. ''Biology of Plants'', 7th ed., page 9. (New York: W. H. Freeman, 2005). . This is usually considered distinct from plant anatomy, which is the study of the internal Anatomy, structure of plants, especially at the microscopic level. Plant morphology is useful in the visual identification of plants. Recent studies in molecular biology started to investigate the molecular processes involved in determining the conservation and diversification of plant morphologies. In these studies transcriptome conservation patterns were found to mark crucial ontogenetic transitions during the plant life cycle which may result in evolutionary constraints limiting diversification. Scope Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarit ...

Flora Of Campeche
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Honduras
The flora and fauna of Honduras reflects the country's geographical location inside the tropics. This has allowed for diverse species of plants and animals to be adapted, but some of them are now in danger of extinction. This has posed the Honduran government, offices and nature organizations to look after the protection of the local environment, like the creation of nature reserves. Flora The flora of Honduras is varied. Pluvioselva, classified a tropical rain forest, is one of its most impressive vegetal populations. Ecologists designated it "Hygrophilous Megatherm Type", for corresponding to regions of high humidity and constant high temperatures, with a single dominant species, like pines or firs, covering big areas. The eastern part of the country, '' La Mosquitia'', has many creeper and climbing plants, such as lianas. There is a great variety of epiphytes, most strikingly the orchids. Adapted to the humid environment, trees are enormous and do not possess deep roots, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Guatemala
According to Parkswatch and the IUCN, Guatemala is considered the fifth biodiversity hotspot in the world. The country has 14 ecoregions ranging from mangrove forest (4 species), in both ocean littorals, dry forests and scrublands in the eastern highlands, subtropical and tropical rain forests, wetlands, cloud forests in the Verapaz region, mixed forests and pine forests in the highlands. Over one third of Guatemala (36.3% or about 39,380 km²) is forested (2005). About half of the forests (49.7% or roughly 19,570 km²) is classified as primary forest which is considered the most biodiverse forest type. Tree species include 17 conifers (pines, cypress, including the endemic '' Abies guatemalensis''), the most in any tropical region of the world. Guatemala has 7 wetlands of international importance that were included in the Ramsar List. Guatemala has some 1246 known species of amphibians, birds, mammals and reptiles according to figures from the World Conservation M ...

Research
Research is "creativity, creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, Discovery (observation), discovery, interpretation (philosophy), interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemology, epistemologies, which vary considerably both within and between humanities and sciences. ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.
