Anders Sparrman
Anders Sparrman (27 February 1748, Tensta, Uppland – 9 August 1820) was a Swedish naturalist, abolitionist and an apostle of Carl Linnaeus. Biography left, Miniature of Sparrman at the time of his travels with James Cook. By unknown artist. Sparrman was the son of a clergyman. At the age of nine he enrolled at Uppsala University, beginning medical studies at fourteen and becoming one of the outstanding pupils of Linnaeus. In 1765 he went on a voyage to China as ship's doctor, returning two years later and describing the animals and plants he had encountered. On this voyage he met Carl Gustaf Ekeberg. He sailed for the Cape of Good Hope in January 1772 to take up a post as a tutor. When James Cook arrived there later in the year at the start of his second voyage, Sparrman was taken on as assistant naturalist to Johann and Georg Forster. After the voyage he returned to Cape Town in July 1775 and practiced medicine, earning enough to finance a journey into the interior. He ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Tahiti
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] |
Pomarea
''Pomarea'' is a genus of birds in the monarch flycatcher family Monarchidae. The genus is restricted to the islands of Polynesia. The monarchs of this genus are around 15–19 cm long and most have sexually dimorphic plumage. Taxonomy and systematics Extant species The genus ''Pomarea'' contains six extant species, including one possible extinct: * Rarotonga monarch (''Pomarea dimidiata'') * Tahiti monarch (''Pomarea nigra'') * Marquesan monarch (''Pomarea mendozae'') * Ua Pou monarch (''Pomarea mira'') (Possibly extinct) * Iphis monarch (''Pomarea iphis'') * Fatu Hiva monarch (''Pomarea whitneyi'') Extinct species * †Maupiti monarch (''Pomarea maupitiensis'') * †Nuku Hiva monarch (''Pomarea nukuhivae'') * †Eiao monarch (''Pomarea fluxa'') Former species Formerly, some authorities also considered the following species (or subspecies) as species within the genus ''Pomarea'': * Bougainville monarch (as ''Pomarea erythrosticta'') * Chestnut-bellied monarch (ugiensis) (a ...

Competition (biology)
Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory). Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other. In the study of community ecology, competition within and between members of a species is an important biological interaction. Competition is one of many interacting biotic and abiotic factors that affect community structure, species diversity, and population dynamics (shifts in a population over time). There are three major mechanisms of competition: interference, exploitation, and apparent competition (in order from most direct to least direct). Interference and exploitation competition can be classed as "real" forms of competition, while apparent competition is not, as organisms do not share a resource, but instead share a predator. Competition among membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Society Kingfisher
The Society kingfisher or Tahiti kingfisher (''Todiramphus veneratus'') is a species of bird in the family Alcedinidae. It is endemic to the Society Islands of French Polynesia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. Taxonomy The Society kingfisher was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's '' Systema Naturae''. He placed it with the other kingfishers in the genus ''Alcedo'' and coined the binomial name ''Alcedo venerata''. Gmelin based his description on the "venerated kingsfisher" that had been described in 1782 by the English ornithologist John Latham in his multi-volume ''A General Synopsis of Birds''. Latham had access to a specimen in the Leverian Museum which he erroneously believed had come from the "Friendly Islands", now Tonga in western Polynesia. Latham noted that the Polynesians revered an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goat
The goat or domestic goat (''Capra hircus'') is a domesticated species of goat-antelope typically kept as livestock. It was domesticated from the wild goat (''C. aegagrus'') of Southwest Asia and Eastern Europe. The goat is a member of the animal family Bovidae and the tribe Caprini, meaning it is closely related to the sheep. There are over 300 distinct breeds of goat.Hirst, K. Kris"The History of the Domestication of Goats".''About.com''. Accessed August 18, 2008. It is one of the oldest domesticated species of animal, according to archaeological evidence that its earliest domestication occurred in Iran at 10,000 calibrated calendar years ago. Goats have been used for milk, meat, fur, and skins across much of the world. Milk from goats is often turned into goat cheese. Female goats are referred to as ''does'' or ''nannies'', intact males are called ''bucks'' or ''billies'', and juvenile goats of both sexes are called ''kids''. Castrated males are called ''wethers''. Whil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spathodea Campanulata
''Spathodea'' is a genus in the plant family Bignoniaceae. The single species it contains, ''Spathodea campanulata'', is commonly known as the African tulip tree. The tree grows between tall and is native to tropical dry forests of Africa. It has been nominated as among 100 of the "World's Worst" invaders. This tree is planted extensively as an ornamental tree throughout the tropics and is much appreciated for its very showy reddish-orange or crimson (rarely yellow), campanulate flowers. The generic name comes from the Ancient Greek words σπαθη (''spathe'') and οιδα (''oida''), referring to the spathe-like calyx. It was identified by Europeans in 1787 on the Gold Coast of Africa. Description The flower bud is ampule-shaped and contains water. Children sometimes play with these buds because of their ability to squirt water. The sap sometimes stains yellow on fingers and clothes. The open flowers are cup-shaped and hold rain and dew, making them attractive to many spec ...

Miconia Calvescens
''Miconia calvescens'', the velvet tree, miconia, or bush currant, is a species of flowering plant in the family Melastomataceae. It is native to Mexico and Central and South America and it has become one of the world's most invasive species. Miconia trees can flower several times a year and bear fruit simultaneously. The inflorescences are large panicles of white to light pink blossoms. The tiny purple fruits are about half a centimeter in diameter and packed with about 120–230 minuscule seeds. The sweet fruits are attractive to birds and other animals which disperse the seeds. A young tree with only two flower panicles can produce seeds in its first fruiting season. This heavy seed production and potential for long-distance dispersal help make miconia an invasive threat. The seeds can lie dormant in the soil of the forest for more than 12 years, and whenever a break in the canopy allows sun to shine through to a patch of soil the seeds there undergo germination. Once the pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...
