Melochia Villosissima
''Melochia villosissima'' ( Chamorro: ), is a tree endemic to northwest Pacific Ocean islands, including South Iwo Jima and western Micronesian Islands ( Caroline and Mariana Islands). It is a small pioneer tree often found along roadsides and has a striking appearance due to its clusters of pink flowers. The Chamorro name for the plant was transliterated into French as ''sidjiafi'' by the French botanist, Charles Gaudichaud-Beaupré, during his exploration of Guam in 1819.

Micronesia
Micronesia (, ) is a subregion of Oceania, consisting of approximately 2,000 small islands in the Northwestern Pacific Ocean. It has a close shared cultural history with three other island regions: Maritime Southeast Asia to the west, Polynesia to the east, and Melanesia to the south—as well as with the wider community of Austronesian peoples. The region has a tropical marine climate and is part of the Oceanian realm. It includes four main archipelagos—the Caroline Islands, the Gilbert Islands, the Mariana Islands, and the Marshall Islands — as well as numerous islands that are not part of any archipelago. Political control of areas within Micronesia varies depending on the island, and is distributed among six sovereign nations. Some of the Caroline Islands are part of the Republic of Palau and some are part of the Federated States of Micronesia (often shortened to "FSM" or "Micronesia"—not to be confused with the identical name for the overall region).

Glabrous
Glabrousness () is the technical term for a lack of hair, down, setae, trichomes, or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent''. In the model plant ''Arabidopsis thaliana'', trichome formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dededo
Dededo (; Spanish: ) is the most populated village in the United States territory of Guam. According to the U.S. Census Bureau, Dededo's population was just under 45,000 in 2020. The village is located on the coral plateau of Northern Guam. The greater Dededo-Machanao-Apotgan Urban Cluster had a population of 139,825 as of the 2010 census, making up 87.7% of Guam's population and 29.8% of its area. Etymology The origin of the village name Dededo (CHamoru: ''Dedidu''), may have come from measuring the original village using fingers, as the Spanish word for finger is ''dedo''. Another possibility is the word ''dededo'' comes from the word ''dedeggo'', "heel of the foot," or ''deggo,'' "to walk on tiptoes." History Before World War II, the main portion of Dededo was at the bottom of Macheche Hill. Dededo grew into a major village after the war when the U.S. Navy constructed housing for displaced Guamanians, and for laborers from off-island helping Guam's development. Foll ...

Indumentum
In biology, an indumentum (Latin, literally: "garment") is a covering of trichomes (fine "hairs") on a plant or of bristles (rarely scales) of an insect. Plants The indumentum on plants can have a wide variety of functions, including as anchorage in climbing plants (e.g., '' Galium aparine''), in transpiration control, in water absorption ('' Tillandsia''), the reflection of solar radiation, increasing water-repellency (e.g., in the aquatic fern '' Salvinia''), in protection against insect predation, and in the trapping of insects ('' Drosera'', '' Nepenthes'', '' Stylosanthes''). Plant indumentum types include *hirsute *lanate *pilose *pubescent *scabrous *scurfy *stellate * tomentose *villous Insects The use of an indumentum on insects can be pollen-related as on bees, sensory like whiskers, or for other uses including adhesion and poison.

Charles Gaudichaud-Beaupré
Charles Gaudichaud-Beaupré (September 4, 1789 – January 16, 1854) was a French botanist. Biography Gaudichaud was born in Angoulême, to J-J. Gaudichaud and Rose (Mallat) Gaudichaud. He studied pharmacology informally at Cognac and Angoulême, and then under Robiquet in Paris, where he acquired a knowledge of botany from Desfontaines and Louis Richard. In April 1810, he was appointed pharmacist in the military marine, and from July 1811 to the end of 1814, he served in Antwerp. He also studied chemistry and herbology. His greatest claim to fame was serving as botanist on a circumglobal expedition from 1817 to 1820. He accompanied Freycinet, who made the expedition on the ships ''Uranie'' and ''Physicienne''. The wreck of the ''Uranie'' in the Falkland Islands, at the close of 1819, deprived him of more than half the botanical collections he had made in various parts of the world. He is also known for his collections in Australia. In 1831, Gaudichaud sailed on ''L'Hermini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pioneer Species
Pioneer species are resilient species that are the first to colonize barren environments, or to repopulate disrupted biodiverse steady-state ecosystems as part of ecological succession. Various kinds of events can create good conditions for pioneers, including disruption by natural disasters, such as wildfire, flood, mudslide, lava flow or a climate-related extinction event, or by anthropogenic habitat destruction, such as through land clearance for agriculture or construction or industrial damage. Pioneer species play an important role in creating soil in primary succession, and stabilizing soil and nutrients in secondary succession. For humans, because pioneer species quickly occupy disrupted spaces, they are sometimes treated as weeds or nuisance wildlife, such as the common dandelion or stinging nettle. Even though humans have mixed relationships with these plants, these species tend to help improve the ecosystem because they can break up compacted soils and accumulate ...

Mariana Islands
The Mariana Islands ( ; ), also simply the Marianas, are a crescent-shaped archipelago comprising the summits of fifteen longitudinally oriented, mostly dormant volcanic mountains in the northwestern Pacific Ocean, between the 12th and 21st parallels north and along the 145th meridian east. They lie south-southeast of Japan, west-southwest of Hawaii, north of New Guinea, and east of the Philippines, demarcating the Philippine Sea's eastern limit. They are found in the northern part of the western Oceanic sub-region of Micronesia, and are politically divided into two jurisdictions of the United States: the Commonwealth of the Northern Mariana Islands and, at the southern end of the chain, the territory of Guam. The islands were named after the influential Spanish queen Mariana of Austria following their colonization in the 17th century. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated that the people who first settl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caroline Islands
The Caroline Islands (or the Carolines) are a widely scattered archipelago of tiny islands in the western Pacific Ocean, to the north of New Guinea. Politically, they are divided between the Federated States of Micronesia (FSM) in the central and eastern parts of the group, and Palau at the extreme western end. Historically, this area was also called ''Nuevas Filipinas'' or New Philippines, because they were part of the Spanish East Indies and were governed from Manila in the Philippines. The Carolines are scattered across a distance of approximately , from the westernmost island, Tobi (island), Tobi, in Palau, to the easternmost island, Kosrae, a Administrative divisions of the Federated States of Micronesia, state of the FSM. Description The group consists of about 500 small coral islands, east of the Philippines, in the Pacific Ocean. The distance from Yap (one of the larger Caroline islands) to Manila is . Most of the islands are made up of low, flat atoll, coral ato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Iwo Jima
, officially Minami or South Iōtō (written with the same characters) since 18 June 2007 and also formerly known as Santo Agustino, is a uninhabited island in the North Pacific. Located south of Iwo Jima, it is the southernmost of the Volcano Islands, part of the Nanpo Archipelago. Farallon de Pajaros is the next island to its south, away in the Northern Mariana Islands. Occupied by the United States Armed Forces following World War II, South Iwo Jima was restored to Japanese control in 1968. It is now administered as part of Ogasawara Subprefecture in the Tokyo Metropolitan Government. Description The island lies south of Tokyo, SSW of Chichijima. Its area is and the shore length, . Along the shoreline there are few bays and inlets, and it is covered with mostly rocks and little sand. To the rear are sea cliffs that rise to in height.

Elmer Drew Merrill
Elmer Drew Merrill (October 15, 1876 – February 25, 1956) was an American botanist and taxonomist. He spent more than twenty years in the Philippines where he became a recognized authority on the flora of the Asia-Pacific region. Through the course of his career he authored nearly 500 publications, described approximately 3,000 new plant species, and amassed over one million herbarium specimens. In addition to his scientific work he was an accomplished administrator, college dean, university professor and editor of scientific journals.Archives of the Arnold Arboretum Early life Merrill and his twin brother, Dana T. Merrill, Dana, were born and raised in Auburn, Maine, East Auburn, Maine, the youngest of six children born to Daniel C. and Mary (Noyes) Merrill. Merrill showed an early interest in natural history, collecting and identifying plants, birds' eggs, rocks, and minerals. In 1894 he entered the University of Maine with the intention of studying engineering but soon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...
