Pisonia
''Pisonia'' is a genus of flowering plants in the four o'clock flower family, Nyctaginaceae. It was named for Dutch physician and naturalist Willem Piso (1611–1678). Certain species in this genus are known as catchbirdtrees, birdcatcher trees or birdlime trees because they catch birds. The sticky seeds are postulated to be an adaptation of some island species that ensures the dispersal of seeds between islands by attaching them to birds, and also allows the enriching of coralline sands. (Should a fledgling fall to the ground, become entangled in the ''Pisonia'' sticky seeds, and be unable to free itself, then it will starve, and so enrich the soil within the tree's rootzone.) These island species include '' P. brunoniana'' of Australasia and Polynesia and '' P. umbellifera'', which is widespread in the tropical Indo-Pacific region.

Joseph Rock
Joseph Francis Charles Rock (1884 – 1962) was an Austrian-American botanist, explorer, geographer, linguist, ethnographer and photographer. Life Josef Franz Karl Rock was born in Vienna, Austria, the son of a steward of a Polish count. As a result of a generally unhappy childhood and his father's determination that he become a priest, Rock set off on a wandering life in late adolescence. After a few precarious years traveling around Europe, he emigrated to the United States in 1905. He eventually ended up in Honolulu, Hawaii, in 1907, where he would remain for 13 years. Although Rock had no tertiary education, a fact about which he was sensitive and often dissembled, he had a remarkable capability for foreign languages; by the time he reached Hawaii he had a reasonable command of more than half a dozen, including Chinese. Hawaii (1907-1920) Initially Rock taught Latin and natural history at Mills College (now known as Mid-Pacific Institute). With little formal background in t ...

Nyctaginaceae
Nyctaginaceae, the four o'clock family, is a family of around 33 genera and 290 species of flowering plants, widely distributed in tropical and subtropical regions, with a few representatives in temperate regions. The family has a unique fruit type, called an " anthocarp", and many genera have extremely large (>100 µm) pollen grains. The family has been almost universally recognized by plant taxonomists. The APG II system (2003; unchanged from the APG system of 1998), assigns it to the order Caryophyllales in the clade core eudicots. A phylogenetic study by Levin has justified the combination of ''Selinocarpus'' and ''Ammocodon'' into the genus '' Acleisanthes''. The genus ''Izabalea'' is now considered a synonym of ''Agonandra'', a genus in Opiliaceae. A more recent study by Douglas and Manos clarified the relationships among almost all of the genera in the family and demonstrated that a substantial diversification of herbaceous genera has occurred in arid North America.

Anton Heimerl
Anton Heimerl (15 February 1857, Budapest - 4 March 1943, Wien) was an Austrian botanist. Heimerl specialized in research of the plant family Nyctaginaceae, and was the binomial authority of many botanical species. He was author of the sections on Nyctaginaceae, Phytolaccaceae and Achatocarpaceae in Engler & Prantl's "Die Natürlichen Pflanzenfamilien" (Volume 16, 1934). In 1903 the genus ''Heimerlia'' was named after him by Franz Xaver Rudolf von Höhnel, and in 1941 Carl Skottsberg named the genus ''Heimerliodendron'' in his honor.

Monotypic Caryophyllales Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

John Montagu, 4th Earl Of Sandwich
John Montagu, 4th Earl of Sandwich, PC, FRS (13 November 1718 – 30 April 1792) was a British statesman who succeeded his grandfather Edward Montagu, 3rd Earl of Sandwich as the Earl of Sandwich in 1729, at the age of ten. During his life, he held various military and political offices, including Postmaster General, First Lord of the Admiralty, and Secretary of State for the Northern Department. He is also known for the claim that he was the eponymous inventor of the sandwich. Biography Early years John Montagu was born in 1718, the son of Edward Montagu, Viscount Hinchingbrooke. His father died when John was four, leaving him as his heir. His mother soon remarried and he had little further contact with her. He succeeded his grandfather as Earl of Sandwich in 1729, at the age of ten.

James Cook
James Cook (7 November 1728 Old Style date: 27 October – 14 February 1779) was a British explorer, navigator, cartographer, and captain in the British Royal Navy, famous for his three voyages between 1768 and 1779 in the Pacific Ocean and to New Zealand and Australia in particular. He made detailed maps of Newfoundland prior to making three voyages to the Pacific, during which he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands, and the first recorded circumnavigation of New Zealand. Cook joined the British merchant navy as a teenager and joined the Royal Navy in 1755. He saw action in the Seven Years' War and subsequently surveyed and mapped much of the entrance to the St. Lawrence River during the siege of Quebec, which brought him to the attention of the Admiralty and the Royal Society. This acclaim came at a crucial moment for the direction of British overseas exploration, and it led to his commission in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or 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 (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. 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 ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethnographer
Ethnography (from Greek ''ethnos'' "folk, people, nation" and ''grapho'' "I write") is a branch of anthropology and the systematic study of individual cultures. Ethnography explores cultural phenomena from the point of view of the subject of the study. Ethnography is also a type of social research that involves examining the behavior of the participants in a given social situation and understanding the group members' own interpretation of such behavior. Ethnography in simple terms is a type of qualitative research where a person puts themselves in a specific community or organization in attempt to learn about their cultures from a first person point-of-view. As a form of inquiry, ethnography relies heavily on participant observation—on the researcher participating in the setting or with the people being studied, at least in some marginal role, and seeking to document, in detail, patterns of social interaction and the perspectives of participants, and to understand these i ...

Teredo (bivalve)
''Teredo'' is a genus of highly modified saltwater clams which bore in wood and live within the tunnels they create. They are commonly known as "shipworms;" however, they are not worms, but marine bivalve molluscs (phylum ''Mollusca'') in the taxonomic family ''Teredinidae''. The type species is ''Teredo navalis''. The tunneling habit of species in the genus inspired the name of the Teredo network tunneling protocol. The submarine HMS ''Teredo'' may also have been named after this genus, which works invisibly, below the surface, and can be very damaging to marine installations made of wood. Diet Like most marine based bivalves, teredo worms are primarily filter feeders and consume mostly seston, and not wood. Wood supplements their primary diet and is consumed with the assistance of bacteria inside their illcells. However, wood is not a necessary part of their diet and they can live on the surface both of wooden and non-wooden structures. Species Species within the gen ...
