Midway Atoll
Midway Atoll (colloquialism, colloquial: Midway Islands; ; ) is a atoll in the North Pacific Ocean. Midway Atoll is an insular area of the United States and is an Insular area#Unorganized unincorporated territories, unorganized and unincorporated territory. The largest island is Sand Island, which has housing and an airstrip. Immediately east of Sand Island, across the narrow Brooks Channel, is Eastern Island, which is uninhabited and no longer has any facilities. Forming a rough, incomplete circle around the two main islands and creating Midway Lagoon is Spit Island, a narrow reef. Roughly equidistant between North America and Asia, Midway is the only island in the Hawaiian Islands, Hawaiian Archipelago that is not part of the state of Hawaii. Unlike the other Hawaiian islands, Midway observes Samoa Time Zone, Samoa Time (UTC−11:00, i.e., eleven hours behind Coordinated Universal Time), which is one hour behind the time in the Hawaii–Aleutian Time Zone used in Hawaii.

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavan
The flavans are benzopyran derivatives that use the 2-phenyl-3,4-dihydro-2''H''-chromene skeleton. They may be found in plants. These compounds include the flavan-3-ols, flavan-4-ols and flavan-3,4-diols (leucoanthocyanidin). A ''C''-glycosidic flavan can be isolated from cocoa liquor.

Frankia
''Frankia'' is a genus of nitrogen-fixing bacteria that live in symbiosis with actinorhizal plants, similar to the '' Rhizobium'' bacteria found in the root nodules of legumes in the family Fabaceae. ''Frankia'' also initiate the forming of root nodules. This genus was originally named by Jørgen Brunchorst, in 1886 to honor the German biologist Albert Bernhard Frank. Brunchorst considered the organism he had identified to be a filamentous fungus. redefined the genus in 1970 as containing prokaryotic actinomycetes and created the family Frankiaceae within the Actinomycetales. He retained the original name of ''Frankia'' for the genus. __TOC__ Overview Most ''Frankia'' strains are specific to different plant species. The bacteria are filamentous and convert atmospheric nitrogen into ammonia via the enzyme nitrogenase, a process known as nitrogen fixation. They do this while living in root nodules on actinorhizal plants. The bacteria can supply most or all of the nit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinorhizal Plant
Actinorhizal plants are a group of angiosperms characterized by their ability to form a symbiosis with the nitrogen fixing actinomycetota ''Frankia''. This association leads to the formation of nitrogen-fixing root nodules. Actinorhizal plants are distributed within three clades, and are characterized by nitrogen fixation. They are distributed globally, and are pioneer species in nitrogen-poor environments. Their symbiotic relationships with Frankia evolved independently over time, and the symbiosis occurs in the root nodule infection site. Classification Actinorhizal plants are Dicotyledon, dicotyledons distributed within 3 Angiosperm, orders, 8 Family (biology), families and 26 Genus, genera, of the angiosperm clade. All nitrogen fixing plants are classified under the "Nitrogen-Fixing Clade", which consists of the three actinorhizal plant orders, as well as the order fabales. The most well-known nitrogen fixing plants are the Legume, legumes, but they are not classified as act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environment Protection And Biodiversity Conservation Act 1999
The ''Environment Protection and Biodiversity Conservation Act 1999'' (Cth) is an Act of the Parliament of Australia that provides a framework for protection of the Australian environment, including its biodiversity and its natural and culturally significant places. Enacted on 16 July 2000, it established a range of processes to help protect and promote the recovery of threatened species and ecological communities, and preserve significant places from decline. The Act is administered by the Department of Climate Change, Energy, the Environment and Water. Lists of threatened species are drawn up under the Act, and these lists, the primary reference to threatened species in Australia, are available online through the Species Profile and Threats Database (SPRAT). As an Act of the Australian Parliament, it relies for its constitutional validity upon the legislative powers of the Parliament granted by the Australian Constitution, and key provisions of the Act are largely ba ...

Estuaries
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphology, geomorphological features or to water-circulation patterns. They can have many different names, s ...

Bermagui, New South Wales
Bermagui () is a town on the south coast of New South Wales, Australia, in the Bega Valley Shire. It lies on the shores of the southern end of Horseshoe Bay. The name is derived from the Dyirringanj word, ''permageua'', possibly meaning "canoe with paddles". History A wharf was built in Horseshoe Bay in 1888 for the coastal trade. The port was serviced by the Illawarra & South Coast Steam Navigation Company. A 1910 article, "Bermagui – In a Strange Sunset", published by Henry Lawson in '' The Bulletin'' describes a steamer journey from Bermagui to Sydney. Lawson was probably travelling with the Illawarra Steam Navigation Company. In 1880, the Government geologist Lamont Young and four others disappeared while on a boat trip from Bermagui. Their boat was found near Mystery Bay, which is about 15 kilometres north of Bermagui, midway between Bermagui and Narooma, near Tilba. The bay received its name because of the disappearance.
