Thomas Archibald Sprague
Thomas Archibald Sprague (7 October 1877, Edinburgh – 22 October 1958, Cheltenham, Gloucestershire, England) was a Scottish botanist. In 1938 he married botanist Mary Letitia Green, and together they authored several supplements to the ''Index Kewensis''. In 1954, botanist Balle (Simone Balle) published ''Spragueanella'', which is a genus of flowering plants from Tropical Africa belonging to the family Loranthaceae Loranthaceae, commonly known as the showy mistletoes, is a family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them hemiparasites. The three terrestrial species are ''Nuytsia floribunda'' (the W ....

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 ...

Actinidiaceae
The Actinidiaceae are a small family of flowering plants. The family has three genera and about 360 species and is a member of the order Ericales. Distribution They are temperate and subtropical woody vines, shrubs, and trees, native to Asia ('' Actinidia'' or kiwifruit, '' Clematoclethra'', and ''Saurauia'') and Central America and South America (''Saurauia'' only). ''Saurauia'', with its 300 species, is the largest genus in this family. Although now confined to Asia and tropical Central and South America, evidence indicates in the past the family had a wider distribution. The now extinct genus ''Parasaurauia'' is thought to have belonged to the Actinidiaceae and lived in North America during the early Campanian. Characteristics The plants are usually small trees or shrubs, or sometimes vines (''Actinidia''). The alternate, simple, spiral leaves have serrated or entire margins. They lack stipules or are minutely stipulated. They are often beset with rather flattened brist ... [...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] |
Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Saurauia
''Saurauia'' is a genus of plants in the family Actinidiaceae. It comprises about over 300 species distributed in the tropics and subtropics of Asia and South and Central America. Genetic evidence and the cell biology of the group support monophyly of the genus. Monophyly of the genus is also supported by micromorphological characters and by phylogenetic analysis, although the exact evolutionary relationships of ''Saurauia'' with the other two genera of the Actinidiaceae, ''Actinidia'' and ''Clematoclethra'', are not well understood. It is also the only extant genus within its family whose natural distribution includes areas outside of Asia (tropical South and Central America). Description The floral characteristics of ''Saurauia'' are similar to those in the other members of the Actinidiaceae. The main floral differences between ''Saurauia'' and the other members are that the species of ''Saurauia'' have 3-5 carpels while ''Actinidia'' has 3-30 or more and ''Clematoclethra'' has ...

Least Concern Plants
Comparison is a feature in the morphology or syntax of some languages whereby adjectives and adverbs are inflected to indicate the relative degree of the property they define exhibited by the word or phrase they modify or describe. In languages that have it, the comparative construction expresses quality, quantity, or degree relative to ''some'' other comparator(s). The superlative construction expresses the greatest quality, quantity, or degree—i.e. relative to ''all'' other comparators. The associated grammatical category is degree of comparison. The usual degrees of comparison are the ''positive'', which simply denotes a property (as with the English words ''big'' and ''fully''); the ''comparative'', which indicates ''greater'' degree (as ''bigger'' and ''more fully''); and the ''superlative'', which indicates ''greatest'' degree (as ''biggest'' and ''most fully''). Some languages have forms indicating a very large degree of a particular quality (called ''elative'' in Semit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
