Dubautia Waialealae
''Dubautia waialealae'' is a rare species of flowering plant in the family Asteraceae known by the common name Wai'ale'ale dubautia. Like other ''Dubautia'' this plant is called ''na`ena`e''.USFWSSpecies Reports: Listed Plants./ref> Distribution and habitat ''Dubautia waialealae'' is endemic to Hawaii, where it is known only from Mount Waiʻaleʻale on Kauai. One individual was seen outside the range, about 14 kilometers away, but this plant is now dead. A recent count estimates a total population of about 3000 plants. The plant grows in boggy wet forest habitat on the mountain summit that is considered one of the rainiest spots on earth, if not the rainiest.Tizon, T. AHe's All Wet and Glad of It.''Los Angeles Times'' April 20, 2006. It grows in habitat around the famous Mount Waiʻaleʻale rain gauge, which measures 460 inches (38.3 feet) [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Rock
Joseph Francis Charles Rock (1884 – 1962) was an Austrian-American botanist, explorer, geographer, linguist, ethnographer and photographer. Life Josef Franz Karl Rock was born in Vienna, Austria, the son of a steward of a Polish count. As a result of a generally unhappy childhood and his father's determination that he become a priest, Rock set off on a wandering life in late adolescence. After a few precarious years traveling around Europe, he emigrated to the United States in 1905. He eventually ended up in Honolulu, Hawaii, in 1907, where he would remain for 13 years. Although Rock had no tertiary education, a fact about which he was sensitive and often dissembled, he had a remarkable capability for foreign languages; by the time he reached Hawaii he had a reasonable command of more than half a dozen, including Chinese. Hawaii (1907-1920) Initially Rock taught Latin and natural history at Mills College (now known as Mid-Pacific Institute). With little formal background in t ...

Head (botany)
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...

Dubautia
''Dubautia'' is a genus of flowering plant in the family Asteraceae. The genus was named after Joseph Eugène DuBaut (1796-1832), an officer in the French Navy who participated in Freycinet's expedition. The entire genus is endemic to Hawaii. It contains more species than the other two genera in the silversword alliance, including cushion plant A cushion plant is a compact, low-growing, mat-forming plant that is found in alpine, subalpine, arctic, or subarctic environments around the world. The term "cushion" is usually applied to woody plants that grow as spreading mats, are limited in ...s, shrubs, trees, and lianas.

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andropogon Virginicus
''Andropogon virginicus'' is a species of grass known by several common names, including broomsedge bluestem, yellowsedge bluestem and (in Australia, because it was introduced to that country after being used as packaging for bottles of American whiskey) whiskey grass. It is native to the southeastern United States and as far north as the Great Lakes. It is known as an introduced species in California and Hawaii, where it is weedy. Invasive species ''Andropogon virginicus'' has also been introduced to Japan and Australia. It competes with other species by allelopathy, releasing persistent herbicidal chemicals from its dying tissues, such as decaying leaves. ''A. virginicus'' colonizes disturbed areas such as abandoned mining sites. It is a weed of pastures and grazing ranges, where it proves less palatable and nutritious to cattle than other grasses. This species is tolerant of fire and grows back quickly and more abundantly after a burn. It is perhaps most problematic in Hawa ...

Juncus
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plants that superficially resemble grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the most widespread and familiar species, the leaves are reduced t ... [...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 ...

Feral Goat
The feral goat is the domestic goat (''Capra aegagrus hircus'') when it has become established in the wild. Feral goats occur in many parts of the world. Species Feral goats consist of many breeds of goats, all of which stem from the wild goat, ''C. aegagrus''. Although breeds can look different, they all share similar characteristics. Physically, both domestic and feral goats can be identified by their prominent straight horns (more prominent on male goats), rectangular pupils, and coarse hair. In addition, most domesticated goats/feral goats lie around 100 – 120lbs, with heavier goats tending to be wild goats. Behavior The feral goat is seen in Australia, New Zealand, Ireland, Great Britain, Hawaii, Brazil, Honduras, Lebanon, Panama, Madagascar, Comoro Islands, Mauritius, Réunion, New Guinea, the Galapagos, Cuba and in many other parts of the world. When feral goats reach large populations in habitats which are not adapted to them, they may become an invasive species w ...

Feral Pig
The feral pig is a domestic pig which has gone feral, meaning it lives in the wild. They are found mostly in the Americas and Australia. Razorback and wild hog are Americanisms applied to feral pigs or boar-pig hybrids. Definition A feral pig is a domestic pig that has escaped or been released into the wild, and is living more or less as a wild animal, or one that is descended from such animals. Zoologists generally exclude from the ''feral'' category animals that, although captive, were genuinely wild before they escaped. Accordingly, Eurasian wild boar, released or escaped into habitats where they are not native, such as in North America, are not generally considered feral, although they may interbreed with feral pigs. Likewise, reintroduced wild boars in Western Europe are also not considered feral, despite the fact that they were raised in captivity prior to their release. In the New World North America Domestic pigs were first introduced to the Americas in the 16th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silversword Alliance
The silversword alliance, also known as the tarweeds, refers to an adaptive radiation of around 30 species in the composite or sunflower family, Asteraceae. The group is endemic to Hawaii, and is derived from a single immigrant to the islands. For radiating from a common ancestor at an estimated 5.2±0.8 Ma, the clade is extremely diverse, composed of trees, shrubs, subshrubs, mat-plants, cushion plants, rosette plants, and lianas. The silversword alliance is named for its most famous and visually striking members, the silverswords. The species of the clade break down into three genera: ''Wilkesia, Argyroxiphium,'' and ''Dubautia.'' There are three species of silverswords and two greenswords in the genus ''Argyroxiphium'', confined to the islands of Maui and Hawaii, and two species of ''Wilkesia'' (''iliau'') on Kauai. The bulk of the species are placed in the genus ''Dubautia'', which is widespread on all the main islands. The genus ''Dubautia'' contains a wide variety of form ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Honolulu Star-Bulletin
The ''Honolulu Star-Bulletin'' was a daily newspaper based in Honolulu, Hawaii, United States. At the time publication ceased on June 6, 2010, it was the second largest daily newspaper in the state of Hawaii (after the ''Honolulu Advertiser''). The ''Honolulu Star-Bulletin'', along with a sister publication called ''MidWeek'', was owned by Black Press of Victoria, British Columbia, Canada and administered by a council of local Hawaii investors. The daily merged with the ''Advertiser'' on June 7, 2010, to form the ''Honolulu Star-Advertiser'', after Black Press's attempts to find a buyer fell through. History Farrington Era The ''Honolulu Star-Bulletin'' traces its roots to the Feb. 1, 1882, founding of the ''Evening Bulletin'' by J. W. Robertson and Company. In 1912, it merged with the ''Hawaiian Star'' to become the ''Honolulu Star-Bulletin''. Wallace Rider Farrington, who later became territorial governor of Hawaii, was the editor of the newspaper from 1898 and the president ...
