William Hillebrand
Wilhelm or William Hillebrand (November 13, 1821 – July 13, 1886) was a German physician. He practiced medicine in several different countries, including for over 20 years in the Hawaiian islands. In 1850, Hillebrand lived at what is now Foster Botanical Garden in Honolulu and gained acknowledgement as a botanist. Life and career Hillebrand was born on November 13, 1821, in Nieheim, Province of Westphalia, Prussia. His father was Judge Franz Josef Hillebrand, and mother Louise Pauline Konig. He studied medicine at Heidelberg and Berlin, and practiced at Paderborn. He sought a warmer climate to recover from a lung problem, (perhaps tuberculosis), first traveling to Australia in 1849, and then the Spanish East Indies, Philippines. Hillebrand then went to San Francisco and finally arrived in the Kingdom of Hawaii, Hawaii on December 22, 1850. He stayed for a little over 20 years and made significant contributions to local medical practice. He was able to speak the Hawaiian langu ...

Pear
Pears are fruits produced and consumed around the world, growing on a tree and harvested in the Northern Hemisphere in late summer into October. The pear tree and shrub are a species of genus ''Pyrus'' , in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees. The tree is medium-sized and native to coastal and mildly temperate regions of Europe, North Africa, and Asia. Pear wood is one of the preferred materials in the manufacture of high-quality woodwind instruments and furniture. About 3,000 known varieties of pears are grown worldwide, which vary in both shape and taste. The fruit is consumed fresh, canned, as juice, or dried. Etymology The word ''pear'' is probably from Germanic ''pera'' as a loanword of Vulgar Latin ''pira'', the plural of ''pirum'', akin to Greek ''apios'' (from Mycenaean ''ápisos''), of Semitic origin (''pirâ''), meaning "fru ...

Clermontia
The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, subfamily Lobelioideae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera involved can be broadly separated based on growth habit: ''Clermontia'' are typically branched shrubs or small trees, up to tall, with fleshy fruits; ''Cyanea'' and ''Delissea'' are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; ''Lobelia'' and ''Trematolobelia'' have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar ''Brighamia'' have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits. The relationships among the genera and sections remains unsettled . Many species have beauti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hakalau Forest National Wildlife Refuge
Hakalau Forest National Wildlife Refuge is a protected area on the Big Island of Hawaii. It is one of two units, along with the Kona Forest National Wildlife Refuge that is managed as part of the Big Island National Wildlife Refuge Complex. Access to the Kona Forest is restricted since it contains several endangered species. Description Hakalau Forest NWR contains some of the finest remaining stands of native montane wet forest in Hawaii. The slopes below feet receive very high rainfall - annually. Bogs, fern patches, and scrubby forest dominate this area, which is dissected by numerous deep gulches. Rainfall decreases to about at elevations above , where majestic koa (''Acacia koa'') and red-blossomed ōhia lehua (''Metrosideros polymorpha'') trees form a closed-canopy forest. Further upslope, above , rainfall decreases to or less and native forest merges into abandoned pastureland where alien grasses and weeds, introduced as forage for cattle, are the dominant vegetatio ...

Seed Dispersal
In Spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living ( biotic) vectors such as birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy fruit. However, this simplified view may ignor ...

Frugivore
A frugivore is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is a form of mutualism. Frugivore seed dispersal Seed dispersal is important for plants because it allows their progeny to move away from their parents over time. The advantages of seed dispersal may have led to the evolution of fleshy fruits, which entice animals to consume them and move the plant's seeds from place to place. While many fruit-producing plant species would not disperse far without frugivores, their seeds can usually germinate even if they fall to the ground directl ...

Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the embr ...

Nectarivore
In zoology, a nectarivore is an animal which derives its energy and nutrient requirements from a diet consisting mainly or exclusively of the sugar-rich nectar produced by flowering plants. Nectar as a food source presents a number of benefits as well as challenges. It is essentially a solution of (as much as 80%) the simple sugars sucrose, glucose and fructose, which are easily ingested and digested, representing a rich and efficient source of nutrition. This solution is often diluted either by the plant that produces it or by rain falling on a flower and many nectarivores possess adaptations to effectively rid themselves of any excess water ingested this way. However, nectar is an incomplete source of nutrition. While it does contain proteins and amino acids, these are found in low quantities, and it is severely deficient in minerals and vitamins. Very few organisms consume nectar exclusively over their whole life cycle, either supplementing it with other sources, particularly ...

Pennisetum Clandestinum
The tropical grass species ''Cenchrus clandestinus'' (previously Pennisetum clandestinum) is known by several common names, most often kikuyu grass, as it is native to the highland regions of East Africa that is home to the Kikuyu people. Because of its rapid growth and aggressive nature, it is categorised as a noxious weed in some regions. However, it is also a popular garden lawn species in Australia, New Zealand, South Africa and the southern region of California in the United States, as it is inexpensive and moderately drought-tolerant. In addition, it is useful as pasture for livestock grazing and serves as a food source for many avian species, including the long-tailed widowbird. The flowering culms are very short and "hidden" amongst the leaves, giving this species its specific epithet (''clandestinus''). Description and habitat ''Cenchrus clandestinus'' is a rhizomatous grass with matted roots and a grass-like or herbaceous habit. The leaves are green, flattened or ...

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] |
