Thekla Resvoll
Thekla Susanne Ragnhild Resvoll (22 May 1871 – 14 June 1948) was a Norwegian botanist and educator. She was a pioneer in Norwegian natural history education and nature conservation together with her sister, Hanna Resvoll-Holmsen. Biography Resvoll was born at Vågå in Oppland, Norway. She was the daughter of Hans Resvoll (1823–1908) and Julie Martine Deichman (1831–1902). She worked as a nurse in an upper-class home in Stockholm before commencing studies of natural history at the Royal Frederick University (now University of Oslo) in Kristiania 1894. She became an adept of the professor of botany, Axel Blytt. After her graduation in 1899, she went to Copenhagen where she worked at the University of Copenhagen's botanical laboratory under Professor Eugen Warming. In 1900, she returned to the University of Oslo. She was made an associate professor at the University Botanical Garden in 1902. She obtained her doctorate in 1918 on the basis of a thesis entitled ''On Pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clonal Propagation
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturists have developed asexual propagation techniques that use vegetative propagules to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making them more challenging to propagate. Background Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts. While man ...

Ecological Succession
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire) or more or less. Bacteria allows for the cycling of nutrients such as carbon, nitrogen and sulphur. The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment. Succession is a process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ranunculus Glacialis
''Ranunculus glacialis'', the glacier buttercup or glacier crowfoot, is a plant of the family Ranunculaceae. It is a 5-10(-20) cm high perennial herb. Often with a single relatively large (1.8 - 3.8 cm) flower, with 5 petals first white later pink or reddish. The underside of the 5 sepals are densely brown-hairy. The leaves are fleshy, shiny, and deeply loped, forming 3 leaflets. ''Ranunculus glacialis'' reported (from Greenland material) to have a diploid chromosome number of 2n = 16. Distribution and habitat ''Ranunculus glacialis'' is an Arctic–alpine species, found in the high mountains of southern Europe (Alps, Pyrenees, Carpathians, Sierra Nevada) as well as on the Scandinavian peninsula, Iceland, the Faroe Islands, Jan Mayen, Svalbard, eastern Greenland and Finland, where is endangered and protected. It has been described as being one of the highest-ascending plant in the Alps, flowering at over 4,000 m. It is found in fell-field and snow-bed sites, on e ...

Norwegian Academy Of Science And Letters
The Norwegian Academy of Science and Letters ( no, Det Norske Videnskaps-Akademi, DNVA) is a learned society based in Oslo, Norway. Its purpose is to support the advancement of science and scholarship in Norway. History The Royal Frederick University in Christiania was established in 1811. The idea of a learned society in Christiania surfaced for the first time in 1841. The city of Trondhjem had no university, but had a learned society, the Royal Norwegian Society of Sciences and Letters, established in 1760. The purpose of a learned society in Christiania was to support scientific studies and aid publication of academic papers. The idea of the Humboldt-inspired university, where independent research stood strong, had taken over for the instrumental view of a university as a means to produce civil servants. The city already had societies for specific professions, for instance the Norwegian Medical Society which was founded in 1833. However, these societies were open for both acad ...

Women's Suffrage
Women's suffrage is the right of women to vote in elections. Beginning in the start of the 18th century, some people sought to change voting laws to allow women to vote. Liberal political parties would go on to grant women the right to vote, increasing the number of those parties' potential constituencies. National and international organizations formed to coordinate efforts towards women voting, especially the International Woman Suffrage Alliance (founded in 1904 in Berlin, Germany). Many instances occurred in recent centuries where women were selectively given, then stripped of, the right to vote. The first place in the world to award and maintain women's suffrage was New Jersey in 1776 (though in 1807 this was reverted so that only white men could vote). The first province to ''continuously'' allow women to vote was Pitcairn Islands in 1838, and the first sovereign nation was Norway in 1913, as the Kingdom of Hawai'i, which originally had universal suffrage in 1840, r ...

Norwegian Association For Women's Rights
The Norwegian Association for Women's Rights ( no, italic=no, Norsk Kvinnesaksforening; NKF) is Norway's oldest and preeminent women's and girls' rights organization and works "to promote gender equality and all women's and girls' human rights through political and legal reform within the framework of liberal democracy." Founded in 1884, NKF is Norway's oldest political organization after the Liberal Party. NKF stands for an inclusive, intersectional and progressive mainstream liberal feminism and has always been open to everyone regardless of gender. Headquartered at Majorstuen, Oslo, NKF consists of a national-level association as well as regional chapters based in the larger cities, and is led by a national executive board. NKF has had a central role in the adoption of all major gender equality legislation and reforms since 1884. NKF aims to represent the interests of all those who identify as girls and women. Its basic principle is that full and equal enjoyment of human righ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Rudiment
In ''rudimental drumming'', a form of percussion music, a drum rudiment is one of a number of relatively small patterns which form the foundation for more extended and complex drumming patterns. The term "drum rudiment" is most closely associated with various forms of ''field drumming'', where the snare drum plays a prominent role. In this context "rudiment" means not only "basic", but also ''fundamental''. This tradition of drumming originates in military drumming and it is a central component of martial music. Definition Rudimental drumming has something of a flexible definition, even within drumming societies devoted to that form of drumming. RudimentalDrumming.com defines it as "the study of coordination." The Percussive Arts Society defines it as a particular method for learning the drums—beginning with rudiments, and gradually building up speed and complexity through practicing those rudiments. ''Camp Duty Update'' defines a drum rudiment as an excerpt from a milit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fagaceae
The Fagaceae are a family of flowering plants that includes beeches, chestnuts and oaks, and comprises eight genera with about 927 species. Fagaceae in temperate regions are mostly deciduous, whereas in the tropics, many species occur as evergreen trees and shrubs. They are characterized by alternate simple leaves with pinnate venation, unisexual flowers in the form of catkins, and fruit in the form of cup-like (cupule) nuts. Their leaves are often lobed and both petioles and stipules are generally present. Their fruits lack endosperm and lie in a scaly or spiny husk that may or may not enclose the entire nut, which may consist of one to seven seeds. In the oaks, genus ''Quercus'', the fruit is a non-valved nut (usually containing one seed) called an acorn. The husk of the acorn in most oaks only forms a cup in which the nut sits. Other members of the family have fully enclosed nuts. Fagaceae is one of the most ecologically important woody plant families in the Northern Hemispher ...
