Bulbostylis Neglecta
''Bulbostylis neglecta'', neglected tuft sedge locally, is an endemic member of the Cyperaceae of Saint Helena in the South Atlantic. ''Bulbostylis neglecta'' was first collected by William John Burchell in 1806, although the specimen was not described as a new species until 1884. Since then it had not been recorded again and was presumed extinct until, in May, 2008, during a botanical survey of St Helena, a small population of the sedge was rediscovered by botanists Philip Lambdon and Andrew Darlow of the European Union's South Atlantic Invasive Species Project and by local naturalist Pat Joshua. Subsequent work by the project team located five distinct populations totalling about 4000 plants. The rediscovery is timely as the existing populations are being encroached on by an invasive African fountain grass ''Pennisetum setaceum ''Cenchrus setaceus'', commonly known as crimson fountaingrass, is a C4 perennial bunch grass that is native to open, scrubby habitats in East Af ...

This is a list of botanists who have Wikipedia articles, in alphabetical order by surname. The List of botanists by author abbreviation is mostly a list of plant taxonomists because an author receives a standard abbreviation only when that author originates a new plant name.

Flora Of Saint Helena
The flora of Saint Helena, an isolated island in the South Atlantic Ocean, is exceptional in its high level of endemism and the severe threats facing the survival of the flora. In phytogeography, it is in the phytochorion St. Helena and Ascension Region of the African Subkingdom, in the Paleotropical Kingdom. Endemic and introduced flora The endemic plants of Saint Helena include many notable Cabbage Tree or, "insular arborescent Asteraceae", members of the daisy family which have evolved a shrubby or tree-like habit on islands. Other notable endemics include the closely related St Helena redwood (''Trochetiopsis erythroxylon'') and St Helena dwarf ebony (''Trochetiopsis ebenus''). These are unrelated to the redwood trees of California or to the ebony trees of commerce, being instead in the Mallow family (Malvaceae). Vegetation Today there are three major vegetation zones: the tree-fern thicket of the highest parts of the central ridge; the pastures of middle elevations and the d ...

Bulbostylis
''Bulbostylis'' is a genus of plants in the sedge family. They are sometimes called hairsedges. There are over 200 species of these clump-forming plants of dry grasslands and warm and tropical savannas worldwide. They have solid, rounded, grooved stems and long, thin basal leaves. They bear spikelets of flowers. Selected species: *'' Bulbostylis barbata'' - watergrass *'' Bulbostylis bathiei'' *'' Bulbostylis boeckleriana''Bussmann, R. W., et al.

Pennisetum Setaceum
''Cenchrus setaceus'', commonly known as crimson fountaingrass, is a C4 perennial bunch grass that is native to open, scrubby habitats in East Africa, tropical Africa, the Middle East and south-western Asia. It has been introduced to many parts of the world as an ornamental plant, and has become an invasive species in some of them. It is drought-tolerant, grows fast, reaches 3 feet in height, and has many purple, plumose flower spikes. Environmental threat Fountaingrass has been introduced to the Canary Islands, Sicily, Sardinia, southern Spain, Australia, South Africa, Hawaii, the western United States, southern Florida and New Caledonia. It thrives in warmer, drier areas and threatens many native species, with which it competes very effectively as an invasive species. It also tends to increase the risk of intense wildfires, to which it is well adapted, thus posing a further threat to certain native species. In Europe, Fountain grass is included since 2017 in the list of ... [...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 ...

South Atlantic Invasive Species Project
The South Atlantic Invasive Species Project is a three-year project (December 2006 - December 2009) funded under the European Union EDF 9. The purpose of the project is to increase the capacity of the UK's South Atlantic Overseas Territories to deal with invasive species issues. The territories involved are Saint Helena, Tristan da Cunha, South Georgia and the South Sandwich Islands, the Falkland Islands and Ascension Island. The project is managed by the Royal Society for the Protection of Birds (RSPB) on behalf of the partner governments. In addition to the partner governments, two NGOs: Falklands Conservation and the Saint Helena National Trust are key stakeholders. Project progress The project started with the appointment of two project officers, Andrew Darlow, for Saint Helena, Ascension and Tristan da Cunha, and Brian Summers for the Falkland Islands, South Georgia and South Sandwich Islands. During the course of the project, Dr Phil Lambdon discovered a living example of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Saint Helena
Saint Helena () is a British overseas territory located in the South Atlantic Ocean. It is a remote volcanic tropical island west of the coast of south-western Africa, and east of Rio de Janeiro in South America. It is one of three constituent parts of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha. Saint Helena measures about and has a population of 4,439 per the 2021 census. It was named after Helena, mother of Constantine I. It is one of the most remote islands in the world and was uninhabited when discovered by the Portuguese enroute to the Indian subcontinent in 1502. For about four centuries the island was an important stopover for ships from Europe to Asia and back, while sailing around the African continent, until the opening of the Suez canal. St Helena is the United Kingdom's second-oldest overseas territory after Bermuda. Saint Helena is known for being the site of Napoleon's second exile, following his final defeat in 1815. ...
