Japanese White-eye In Hawaii
Along with a number of other organisms, the Japanese white-eye (''Zosterops japonicus'') has become an invasive species in Hawaii. Its native range includes much of East Asia, including Japan, China, Vietnam, Taiwan, and the Philippines. Introduced to Hawaii in 1929 as a means of insect control, it has since become a common bird on the Hawaiian islands, and has become a vector for avian parasites that are now known to adversely affect populations of native birds such as Hawaiian honeycreepers, as well as spreading invasive plant species through discarded seeds. Effects on native Hawaiian birds The Japanese white-eye's successful invasion of the Hawaiian Islands can be partially attributed to the lack of coevolution between endemic species and the white-eye.Mountainspring S & Scott JM. (1985) Interspecific Competition Among Hawaiian Forest Birds. Ecological Monographs, 55(2): 219-239. The occurrence of coevolution is driven by species interactions that directly impact physical de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese White-eye
The warbling white-eye (''Zosterops japonicus''), also known as the Japanese white-eye and mountain white-eye, is a small passerine bird in the white-eye family. The specific epithet is occasionally written ''japonica'', but this is incorrect due to the gender of the genus. Its native range includes much of East Asia, including the Russian Far East, Japan, Indonesia, Korea, and the Philippines. It has been intentionally introduced to other parts of the world as a pet and as pest control, with mixed results. As one of the native species of the Japanese islands, it has been depicted in Japanese art on numerous occasions, and historically was kept as a cage bird. Taxonomy The warbling white-eye was described by the ornithologists Coenraad Jacob Temminck and Hermann Schlegel in 1845 from a specimen collected in Japan. They coined the binomial name ''Zosterops japonicus''. The English name "Japanese white-eye" was formerly used for ''Zosterops japonicus'' and what are now the Philip ...

Akepa
''Loxops'' is a Hawaiian honeycreeper genus in the finch family, Fringillidae. Most of them are commonly known as akepa. Taxonomy There are 5 species in this genus, two of which are recently extinct or possibly extinct: * Akekee or Kauai akepa, ''Loxops caeruleirostris'' * Hawaiʻi ʻakepa, ''Loxops coccineus'' * Hawaiʻi creeper or ʻalawī, ''Loxops mana'' * Maui ʻakepa, ''Loxops ochraceus'' - possibly extinct (1988) * Oʻahu ʻakepa, ''Loxops wolstenholmei'' - extinct (1930s) Molecular analysis supports the genus diverging from its closest relatives, the ''Chlorodrepanis'' ʻamakihis, during the earliest Pleistocene, about 2.47 million years ago. The clade containing both genera is sister to the genus '' Magumma'', which contains the ʻanianiau, from which they diverged during the latest Pliocene, about 2.78 million years ago. Genetic analysis of the extant species supports ''L. mana'' as being the most basal extant member of the group, diverging from the other species ...

Introduced Birds
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] |
Environmental Issues In Hawaii
The majority of environmental issues affecting Hawaii today are related to pressures from increasing human and animal population and urban expansion both directly on the islands as well as overseas. These include the unsustainable impacts of tourism, urbanization, implications of climate change such as sea level rise, pollution, especially marine plastic pollution, and invasive species. Water quality The waters surrounding the Hawaiian Islands are affected by increasing waste products like marine debris from land and ocean sources washing onto shore as well as effluents generated and released from the islands themselves. Oceans in particular are being devastated by factors including marine debris, plastic pollution, and tourism. Marine debris The positioning of Hawaii in particular makes it a high-impact target for marine debris, given the natural ocean currents and its relative location to the North Pacific Subtropical Convergence Zone. As a result, marine debris is not lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Environment Of Hawaii
Hawaii is one of fifty states of the U.S. and covers the Hawaiian Islands, a volcanic archipelago consisting of eight major islands, several atolls and numerous smaller islets. Hawaii became a state of the United States in 1959. Prior to that it was the Territory of Hawaii (1898 to 1959) and originally the Kingdom of Hawaii.

Myrica Faya
''Myrica faya'' (firetree, faya or haya; syn. ''Morella faya'' (Ait.) Wilbur) is a species of ''Myrica'', native to Macaronesia (the Azores, Madeira, and the Canary Islands), and possibly also western coastal mainland Portugal. Description It is an evergreen shrub or small tree tall, rarely up to tall. The leaves are usually a dark, glossy green, long and broad, with an entire margin and a bluntly pointed apex. It easily grows in any type of soil. It is subdioecious, with the male and female flowers produced largely on separate plants, but often with a few flowers of the other sex present (Binggeli 1997). The male flowers have four stamens and are normally produced in clumps close to the branch. The female flowers, usually occurring in similar groups grow slightly farther from the branch tips. The fruit is an edible drupe diameter, it is a reddish purple ripening dark purple to black. It is used as an astringent remedy for catarrh (Pérez 1999, Rushforth 1999). Distributi ...

Bonin Islands
The Bonin Islands, also known as the , are an archipelago of over 30 subtropical and tropical islands, some directly south of Tokyo, Japan and northwest of Guam. The name "Bonin Islands" comes from the Japanese word ''bunin'' (an archaic reading of ''mujin''), meaning "no people" or "uninhabited". The only inhabited islands of the group are Chichijima (), the seat of the municipal government, and Hahajima (). Archeological evidence has revealed that some of the islands may have been prehistorically inhabited by members of an unknown Micronesian ethnicity. Ogasawara Municipality (''mura'') and Ogasawara Subprefecture take their names from the Ogasawara Group. The is also used as a wider collective term that includes other islands in Ogasawara Municipality, such as the Volcano Islands, along with three other remote islands ( Nishinoshima, Minamitorishima, and Okinotorishima). Geographically speaking, all of these islands are parts of the Nanpō Islands. A total population of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Diversity
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species. It is distinguished from ''genetic variability'', which describes the tendency of genetic characteristics to vary. Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele. The population will continue for more generations because of the success of these individuals. The academic field of population genetics includes several hypotheses and theories regarding genetic diversity. The neutral theory of evolution proposes that diversity is the result of the accumulation of neutral substitutions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outcrossing
Out-crossing or out-breeding is the technique of crossing between different breeds. This is the practice of introducing distantly related genetic material into a breeding line, thereby increasing genetic diversity. Outcrossing can be a useful technique in Animal husbandry, animal breeding. The outcrossing breeder intends to remove the traits by using "new blood." With dominant traits, one can still see the expression of the traits and can remove those traits whether one outcrosses, line breeds or inbreeds. With recessive traits, outcrossing allows for the recessive traits to migrate across a population. Many traits are Mendelian and therefore exhibit a more complicated intermediate phenotype. The outcrossing breeder then may have individuals that have many deleterious genes that may be expressed by subsequent inbreeding. There is now a gamut of deleterious genes within each individual in many dog breeds. Increasing the variation of genes or alleles within the gene pool may pro ...

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 ...
