Nesogenes Rotensis
''Nesogenes rotensis'' is a rare species of flowering plant in the family Orobanchaceae. It is endemic to Rota, one of the Northern Mariana Islands in the Pacific Ocean.

Francis Raymond Fosberg
Francis Raymond Fosberg (20 May 1908 – 25 September 1993) was an American botanist. A prolific collector and author, he played a significant role in the development of coral reef and island studies. History Ray Fosberg was born in Spokane, Washington but grew up in Turlock, California. He received a B.A. in Botany at Pomona College in 1930. Fosberg worked as a plant researcher at the Los Angeles County Museum, specializing in plants from islands on the coast of California and of the desert Southwest. He became interested in island ecosystems, and in 1932 moved to Honolulu to work at the University of Hawaii as an assistant to Harold St. John. There he received an invitation to participate in the Mangarevan Expedition led by the malacologist Charles Montague Cooke, Jr. The expedition visited 25 high islands and 31 coral islands, and Fosberg and St. John brought back 15,000 plant specimens. Fosberg received his M.S. in Botany from the University of Hawaii in 1937 and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Endemic Plants In The Mariana Islands
Micronesia is a biodiversity hotspot with an exceptionally high richness of endemic plant species, 10 times higher than that of Hawaii. The Mariana Islands form an archipelago in the northwest of the Micronesian region. In 2012, Craig M. Costion and David H. Lorence compiled a list of Micronesian endemic plants, and assessed that the Mariana Islands had 22 endemic plant species (16 species in the southern Mariana Islands, of which 11 were isolated to Guam, and 5 species in the northern Mariana Islands). They concluded that there was an approximately 3% rate of endemism in the Mariana Islands (endemic species per km2), which is comparable to the rates in Hawaii (4%) and Tonga (2%) but lower than the 14% rate of endemism among all Micronesian islands. However, the number of known Marianas endemics has greatly expanded since then with new discoveries, taxonomic revisions, and improvements in digitized databases.

Typhoon
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seedling
A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). The two classes of flowering plants (angiosperms) are distinguished by their numbers of seed leaves: monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) possess two round cotyledons. Gymnosperms are more varied. For example, pine seedlings have up to eight cotyledons. The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown ab ...

Typhoon Pongsona
Typhoon Pongsona was the last typhoon of the 2002 Pacific typhoon season, and was the second costliest United States disaster in 2002, only behind Hurricane Lili. The name "Pongsona" was contributed by North Korea for the Pacific tropical cyclone list and is the Korean name for the garden balsam. Pongsona developed out of an area of disturbed weather on December 2, and steadily intensified to reach typhoon status on December 5. On December 8 it passed through Guam and the Northern Mariana Islands while near its peak winds of 175 km/h (110 mph 10- min). It ultimately turned to the northeast, weakened, and became extratropical on December 11. Typhoon Pongsona produced strong wind gusts peaking at 290 km/h (183 mph 1-min), which left the entire island of Guam without power and destroyed about 1,300 houses. With strong building standards and experience from repeated typhoon strikes, there were no fatalities directly related to Pongsona, although there ...

Scaevola Taccada
''Scaevola taccada'', also known as beach cabbage, sea lettuce, or beach naupaka, is a flowering plant in the family Goodeniaceae found in coastal locations in the tropical areas of the Indo-Pacific. It is a common beach shrub throughout the Arabian Sea, the tropical Indian Ocean and the tropical islands of the Pacific Ocean. There has long been confusion over the correct scientific name for this species. It is also known by the synonym ''Scaevola sericea''. Description ''Scaevola taccada'' is a large bush reaching up to about 4 m in height typical of littoral zones where it grows very close to the sea exposed to the salt spray, usually on sandy or pebbly soils. Leaves are slightly succulent, about 20 cm long, closely alternate and crowded at the stem tips. They are glabrous with a fleshy-looking yellowish green color. The fruits and flowers are white. ''Scaevola taccada'' blooms the whole year round and the flowers have a fan-like shape which gives them the name fanfl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
