Erling Christophersen
Erling Christophersen (April 17, 1898 – November 9, 1994) was a Norwegian botanist, geographer and diplomat. He participated in and led several notable scientific expeditions in the 20th century, including the fifth Tanager Expedition (1924) to Nihoa and Necker Island and the Norwegian Scientific Expedition to Tristan da Cunha (1937–1938). Early life Christophersen was born in Christiania, Norway (now known as Oslo) in 1898. He attended the University of Christiania from 1918–1921, and received his Ph.D from Yale University in 1924. Christophersen's dissertation, "Soil reaction and plant distribution in the Sylene National Park, Norway", focused on the art and science of applied forest ecology, or silviculture, of alpine plants in Norway.

:Category:Scientific Expeditions
This category includes expeditions whose primary or secondary purpose is scientific research and discovery, such as the '' Expedición Botánica al Virreinato del Perú'' or Charles Darwin's voyages on the ''Beagle''. The category does not include commercial expeditions, such as some of the early whaling expeditions to Antarctica. Many expeditions had a chief purpose of discovery, such as the Luís Vaz de Torres or Lewis and Clark Expedition, but were also commissioned to study the geology, botany, and zoology they were to be found in the unexplored lands. History of science expeditions Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most ... Expeditions Field surveys ...

Silviculture
Silviculture is the practice of controlling the growth, composition/structure, and quality of forests to meet values and needs, specifically timber production. The name comes from the Latin ('forest') and ('growing'). The study of forests and woods is termed ''silvology''. Silviculture also focuses on making sure that the treatment(s) of forest stands are used to conserve and improve their productivity. Generally, silviculture is the science and art of growing and cultivating forest crops, based on a knowledge of silvics (the study of the life-history and general characteristics of forest trees and stands, with particular reference to local/regional factors). The focus of silviculture is the control, establishment and management of forest stands. The distinction between forestry and silviculture is that silviculture is applied at the stand-level, while forestry is a broader concept. Adaptive management is common in silviculture, while forestry can include natural/conserved land ...

Yale University Alumni
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate colleg ...

International Association For Plant Taxonomy
The International Association for Plant Taxonomy (IAPT) is an organization established to promote an understanding of plant biodiversity, facilitate international communication of research between botanists, and oversee matters of uniformity and stability in plant names. The IAPT was founded on July 18, 1950, at the Seventh International Botanical Congress in Stockholm, Sweden. The IAPT headquarters is located in Bratislava, Slovakia. Its president, since 2017, is Patrick S. Herendeen of the Chicago Botanic Garden; vice-president is Gonzalo Nieto Feliner of the Real Jardín Botánico, Madrid; and secretary-general is Karol Marhold of the Plant Science and Biodiversity Centre, Slovak Academy of Sciences, Bratislava. Both the taxonomic journal ''Taxon'' and the series ''Regnum Vegetabile'' are published by the IAPT. The latter series includes the ''International Code of Nomenclature for algae, fungi, and plants'', ''Index Nominum Genericorum'', and ''Index Herbariorum''. Purpos ...

Diospyros
''Diospyros'' is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants. Taxonomy and etymology The generic name ''Diospyros'' comes from a Latin name for the Caucasian persimmon ('' D. lotus''), derived from the Greek διόσπυρος : dióspyros, from ''diós'' () and ''pyrós'' (). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit". Muddled translations sometimes give rise to curious and inappropriate interpretations such as " God's pear" and " Jove's fire". The genus is a large one a ...

Amaranthus Brownii
''Amaranthus brownii'' was an annual herb in the family Amaranthaceae. The plant was found only on the small island of Nihoa in the Northwestern Hawaiian Islands, growing on rocky outcrops at altitudes of . It was one of nine species of ''Amaranthus'' in the Hawaiian Islands, as well as the only endemic Hawaiian species of the genus. It is now considered extinct. ''A. brownii'' was first discovered during the Tanager Expedition in 1923 by botanist Edward Leonard Caum. It differed from other Hawaiian species of ''Amaranthus'' with its spineless leaf axils, linear leaves, and indehiscent fruits. It was one of 26 vascular plants on Nihoa, 17 of which are indigenous, six alien, and three endemic only to Nihoa; these latter three included ''A. brownii'', the Nihoa fan palm or ''loulu'', and the Nihoa carnation. ''A. brownii'' was considered the rarest plant on Nihoa and was not directly observed on the island after 1983. Past expeditions collected plant samples and seeds, but n ...

University Of Hawaii
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...
