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. This plant was federally listed as an endangered species of the United States in 1996.''Delissea subcordata''. The Nature Conservancy. This Hawaiian lobelioid is a |
Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism 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 and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Metrosideros Polymorpha
''Metrosideros polymorpha'', the ''ōhia lehua'',; is a species of flowering evergreen tree in the Myrtus, myrtle family, Myrtaceae, that is Endemism, endemic to the six largest Hawaiian Islands, islands of Hawaii, Hawaii. It is a member of the diverse ''Metrosideros'' genus, which are widespread over the southwest Pacific. It is the state tree of Hawai'i. It is a highly variable tree, being tall in favorable situations, and a much smaller prostrate shrub when growing in Hawaiian tropical rainforests#Bogs, 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 (deity), 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. ''Metrosideros polymorpha'' is commonly called a ''lehua'' tree, or an ' ...

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 (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens fo ...

Feral Pig
A feral pig is a domestic pig The pig (''Sus domesticus''), also called swine (: swine) or hog, is an omnivorous, domesticated, even-toed, hoofed mammal. It is named the domestic pig when distinguishing it from other members of the genus '' Sus''. Some authorities cons ... which has gone feral, meaning it lives in the wild. The term feral pig has also been applied to wild boars, which can interbreed with domestic pigs. They are found mostly in the Americas and Australia. Razorback and wild hog are sometimes used in the United States in reference to feral pigs or boar–pig hybrids. Definition A feral organism, 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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral Goat
The feral goat is the domestic goat (''Capra 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 domestic 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 domestic goats/feral goats weigh around , with heavier goats tending to be wild goats. Behavior The feral goat is seen in Australia, New Zealand, Great Britain, Ireland, Hawaii, Brazil, Honduras, Lebanon, Panama, Madagascar, the Comoros, Mauritius, Réunion, New Guinea, the Galápagos Islands, 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 with seri ...

Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

Understory
In forestry and ecology, understory (American English), or understorey (English in the Commonwealth of Nations, Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the Canopy (biology), 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 tolerance, 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 Cornus (genus), dogwood are understory specialists. In Temperate broadleaf and mixed forest, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Pisonia
''Pisonia'' is a genus of flowering plants in the Mirabilis jalapa, four o'clock flower family, Nyctaginaceae. It was named for Dutch Republic, 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 Seed dispersal#Dispersal by animals, 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 ''Pisonia brunoniana, P. brunoniana'' of Australasia and Polynesia and ''Pisonia umbellifera, P. umbellifera'', which is widespread in the tropical Indo-Pacific region. Species 27 species are accepted. *''P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acacia Koa
''Acacia koa'', commonly known as koa, is a species of Flowering plant, flowering tree in the Family (biology), family Fabaceae. It is Endemism, endemic to the Hawaiian Islands, where it is the second most common tree. The highest populations are on Hawaii (island), Hawaii, Maui and Oahu, Oahu. Name The name ''koa'' in the Hawaiian language ultimately comes from Proto-Austronesian language, 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 language, Cebuano), ''Eusideroxylon zwageri'' (''togas'' in Tombonuwo language, Tombonuwo), and ''Intsia bijuga'' (''dort'' in Palauan language, Palauan) descend from this root. The Hawaiian Acacia koa is closely related to a common tree in Taiwan called ''Acacia confusa''. The two species also share a very similar appearance. ''Koa'' also means brave, bold, fearless, or warrior. Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub or 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 Plant stem, stems and shorter height, less than tall. Small shrubs, less than tall are sometimes termed as subshrubs. Many botany, botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some define a shrub as less than and a tree as over 6 m. Others use as the cutoff point for classification. Many trees do not reach this mature height because of hostile, less than ideal growing conditions, and resemble shrub-sized plants. Others in such species have the potential to grow taller in ideal conditions. For longevity, most shrubs are classified between Perennial plant, perennials and trees. Some only last about five years in good conditions. Others, usually larger and more woody, live beyond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
