Delissea Subcordata
''Delissea subcordata'' is a rare species of flowering plant in the family Campanulaceae known by the common names Koʻolau Range delissea and ''oha''. It is endemic to Hawaii, where it is known only from the island of Oahu. It is now only found in the Waianae Mountains, and it is believed to be extirpated from the Koʻolau Range, where it once occurred. As of 2008 there were 40 individuals remaining, 28 of which were mature plants.USFWS''Delissea subcordata'' Five-year Review.January 2008.

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrosideros Polymorpha
''Metrosideros polymorpha'', the ''ōhia lehua'', is a species of flowering evergreen tree in the myrtle family, Myrtaceae, that is endemic to the six largest islands of Hawaii. It is a highly variable tree, being tall in favorable situations, and a much smaller prostrate shrub when growing in boggy soils or directly on basalt. It produces a brilliant display of flowers, made up of a mass of stamens, which can range from fiery red to yellow. Many native Hawaiian traditions refer to the tree and the forests it forms as sacred to Pele, the volcano goddess, and to Laka, the goddess of hula. Ōhia trees grow easily on lava, and are usually the first plants to grow on new lava flows. It is a common misconception that the word ''ōhia'' is used to refer to the tree and that the word ''lehua'' refers only to its flowers. ''The Hawaiian Dictionary'' (Pukui and Elbert 1986: 199) defines ''lehua'' with these words: "The flower of the ''ōhia'' tree... ''also the tree itself'' mphasis ...

Lobelioideae
Lobelioideae is a subfamily of the plant family Campanulaceae. It contains 32 genera, totalling about 1200 species. Some of the larger genera are ''Lobelia'', ''Siphocampylus'', ''Centropogon'', ''Burmeistera'' and '' Cyanea''. They are perennials, sometimes annuals, ranging in form from herbs to small trees. Most species are tropical in distribution, but in total this subfamily occurs almost worldwide, being absent only from Arctic regions, central Asia and the Near East. The subfamily is particularly diverse in Hawaii, where well over 100 species of Hawaiian lobelioids have radiated from a single introduction. This subfamily was formerly given family rank as Lobeliaceae, under a somewhat different circumscription. The leaves are simple and alternate. The plants have milky sap. The flowers are bilaterally symmetric with five lobes and stamen The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens fo ...

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] |
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 ...

Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. ...

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Planchonella Sandwicensis
''Planchonella sandwicensis'' is a species of flowering tree in the sapodilla family, Sapotaceae, that is endemic to the main islands of Hawaii. Names for this species in the Hawaiian language include ''Ālaa'', ''Āulu'' and ''Ēlaa''. Description ''Ālaa'' inhabits dry, coastal mesic, and mixed mesic forests at elevations of . ''Ālaa'' reaches a height of and a trunk diameter of . The thick bark is grey and fissured, with an orange inner layer. The leaves are alternate, thick, leathery, oblong or elliptical, and measure long and wide. The upper surfaces of the leaves are glabrous and shiny green, while the lower surfaces are dull and may feature bronze or reddish brown pressed hairs. The hairs are sometimes found only on the tips of new leaves (see photo gallery below). Inflorescences with one to four bell-shaped flowers are found at the bases of leaves. The fruit, a berry, is in diameter and yellow, orange, or purplish black. Each fruit contains one to five seed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pisonia
''Pisonia'' is a genus of flowering plants in the four o'clock flower family, Nyctaginaceae. It was named for Dutch physician and naturalist Willem Piso (1611–1678). Certain species in this genus are known as catchbirdtrees, birdcatcher trees or birdlime trees because they catch birds. The sticky seeds are postulated to be an adaptation of some island species that ensures the dispersal of seeds between islands by attaching them to birds, and also allows the enriching of coralline sands. (Should a fledgling fall to the ground, become entangled in the ''Pisonia'' sticky seeds, and be unable to free itself, then it will starve, and so enrich the soil within the tree's rootzone.) These island species include '' P. brunoniana'' of Australasia and Polynesia and '' P. umbellifera'', which is widespread in the tropical Indo-Pacific region.

Acacia Koa
''Acacia koa'' or commonly known as koa is a species of flowering tree in the family Fabaceae. It is endemic to the Hawaiian Islands, where it is the second most common tree. The highest populations are on Hawaii, Maui and Oahu. Name The name ''koa'' in the Hawaiian language ultimately comes from Proto-Austronesian *''teRas'' meaning "core" or "ironwood"; many names referring to certain ironwood or heartwood species in Southeast Asia and Oceania such as ''Vitex parviflora'' (''tugás'' in Cebuano), ''Eusideroxylon zwageri'' (''togas'' in Tombonuwo), and ''Intsia bijuga'' (''dort'' in Palauan) descend from this root. ''Koa'' also means brave, bold, fearless, or warrior. Description Koa is a large tree, typically attaining a height of and a spread of . In deep volcanic ash, a koa tree can reach a height of , a circumference of , and a spread of . It is one of the fastest-growing Hawaiian trees, capable of reaching in five years on a good site.

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
