Plant Life-form
Plant life-form schemes constitute a way of classifying plants alternatively to the ordinary species-genus-family scientific classification. In colloquial speech, plants may be classified as trees, shrubs, herbs (forbs and graminoids), etc. The scientific use of life-form schemes emphasizes plant function in the ecosystem and that the same function or "adaptedness" to the environment may be achieved in a number of ways, i.e. plant species that are closely related phylogeny, phylogenetically may have widely different life-form, for example ''Adoxa moschatellina'' and ''Sambucus nigra'' are from the same family, but the former is a small herbaceous plant and the latter is a shrub or tree. Conversely, unrelated species may share a life-form through convergent evolution. While taxonomic classification is concerned with the production of natural classifications (being natural understood either in philosophical basis for evolution, pre-evolutionary thinking, or phylogenetically as non-pol ...

Scientific Classification
image:Hierarchical clustering diagram.png, 280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the Taxonomy (biology), classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchy, hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a Taxonomy for search e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alga
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthetic organisms that are not plants, and includes species from multiple distinct clades. Such organisms range from unicellular microalgae, such as cyanobacteria, '' Chlorella'', and diatoms, to multicellular macroalgae such as kelp or brown algae which may grow up to in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton. Algae constitute a polyphyletic group because they do not include a common ancestor, and although eukaryotic algae with chlorophyll-bearing plastids seem ...

Eugen Warming
Johannes Eugenius Bülow Warming (3 November 1841 – 2 April 1924), known as Eugen Warming, was a Danish botanist and a main founding figure of the scientific discipline of ecology. Warming wrote the first textbook (1895) on plant ecology, taught the first university course in ecology and gave the concept its meaning and content. Scholar R. J. Goodland wrote in 1975: “''If one individual can be singled out to be honoured as the founder of ecology, Warming should gain precedence''”. Warming wrote a number of textbooks on botany, plant geography and ecology, which were translated to several languages and were immensely influential at their time and later. Most important were '' Plantesamfund'' and ''Haandbog i den systematiske Botanik''. Early life and family life Warming was born on the small Wadden Sea island of Mandø as the only child of Jens Warming (1797–1844), parish minister, and Anna Marie von Bülow af Plüskow (1801–1863). After the early death of his fathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantesamfund
''Plantesamfund - Grundtræk af den økologiske Plantegeografi'', published in Danish in 1895 by Eugen Warming, and in English in 1909 as ''Oecology of Plants: An Introduction to the Study of Plant Communities'', by Warming and Martin Vahl, was the first book to be published having the word ecology in its title. The book has had a lasting impact on the field of ecology, particularly in its German translation soon after its initial publication, and in its expanded and revised English translation. The book was based on Warming's lectures on plant geography at the University of Copenhagen. It gives an introduction to all major biomes of the world. Its aim was to explain how nature solved similar problems (drought, flooding, cold, salt, herbivory) in similar way, despite using very different raw material (species of different descent) in different regions of the world. * Warming, E.

August Grisebach
August Heinrich Rudolf Grisebach (; 17 April 18149 May 1879) was a German botanist and phytogeographer. Biography Grisebach studied at the Lyceum in Hanover, the cloister-school at Ilfeld, and the University of Göttingen. He graduated in medicine from the University of Berlin in 1836. He undertook expeditions to Provence, Turkey, the Balkans, and Norway. In 1837 he became associate professor and in 1847 full professor at the medical faculty in Göttingen and was named director of the botanical garden there in 1875. While his main fields of interest were phytogeography and systematics, especially the Gentianaceae and Malpighiaceae, he considered his ''Flora of the British West Indian Islands'' his most important work. Much of his collection, especially the types of species described by him, are housed at the Göttingen University Herbarium. His taxonomic classification is set out in his ''Grundriss der systematischen Botanik'' (1854). His son Eduard was an author, lawyer a ...

Henry Shoemaker Conard
Henry Shoemaker Conard (1874 - 1971) was a leading authority on bryophytes and water lilies, as well as an early advocate of environmental preservation. From 1906 to 1955, Professor Conard worked at Grinnell College in Grinnell, Iowa.Welch and LeBlanc 1972, p. 558 In 1954, he became the first to receive the Eminent Ecologist Award from the Ecological Society of America, an award that has continued annually ever since. In 1969, Grinnell acquired a plot of cropland and established the Conard Environmental Research Area, in recognition of the legacy of the longtime professor. Early years Conard was born September 12, 1874, in Philadelphia, Pennsylvania, to Thomas Pennington Conard, director of the West Grove boarding school, and Rebecca Savery Baldwin Conard.

Anton Kerner Von Marilaun
Anton Kerner Ritter von Marilaun, or Anton Joseph Kerner, (12 November 1831 – 21 June 1898) was an Austrian botanist, physician, and professor at the University of Innsbruck and later at the University of Vienna. Von Marilaun emphasized the concept of plant sociology or the species that plants were typically found associated with in his geographical studies of species. Inspired by the work of Alexander von Humboldt and others he examined climatological and historical factors in the distributions of plant species. Career Kerner was born in Mautern, Lower Austria, and studied medicine in Vienna, graduating in 1854 with a medical degree. He also studied the flora of Wachau. He then became a teacher at Often and continued his studies in natural history. In 1858 Kerner was appointed professor of botany at the Polytechnic Institute at Buda, and then in 1860 was appointed professor of natural history at the University of Innsbruck.

Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 1769 – 6 May 1859) was a German polymath, geographer, natural history, naturalist, List of explorers, explorer, and proponent of Romanticism, Romantic philosophy and Romanticism in science, science. He was the younger brother of the Prussian minister, philosopher, and linguistics, linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botany, botanical geography laid the foundation for the field of biogeography, while his advocacy of long-term systematic geophysical measurement pioneered modern Earth's magnetic field, geomagnetic and meteorology, meteorological monitoring. Humboldt and Carl Ritter are both regarded as the founders of modern geography as they established it as an independent scientific discipline. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a non-Spanish European scientific point of view. His des ...

Habit (biology)
Habit, equivalent to habitus in some applications in biology, refers variously to aspects of behaviour or structure, as follows: *In zoology (particularly in ethology), ''habit'' usually refers to aspects of more or less predictable ''behaviour'', instinctive or otherwise, though it also has broader application. ''Habitus'' refers to the characteristic form or morphology of a species. *In botany, the plant habit is the characteristic form in which a given species of plant grows.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Behavior In zoology, ''habit'' (not to be confused with ''habitus'' as described below) usually refers to a specific behavior pattern, either adopted, learned, pathological, innate, or directly related to physiology. For example: * ...the atwas in the ''habit'' of springing upon the oor knockerin order to gain admission... * If these sensitive parrots are ...

Historia Plantarum (Theophrastus)
Theophrastus's ''Enquiry into Plants'' or ''Historia Plantarum'' (, ''Peri phyton historia'') was, along with his mentor Aristotle's ''History of Animals'', Pliny the Elder's ''Natural History (Pliny), Natural History'' and Pedanius Dioscorides, Dioscorides's ''De materia medica'', one of the most important books of natural history written in Ancient history, ancient times, and like them it was influential in the Renaissance. Theophrastus looks at plant structure, reproduction and growth; the varieties of plant around the world; wood; wild and cultivated plants; and their uses. Book 9 in particular, on the medicinal plants, medicinal uses of plants, is one of the first herbals, describing juices, gums and resins extracted from plants, and how to gather them. ''Historia Plantarum'' was written some time between c. 350 BC and c. 287 BC in ten volumes, of which nine survive. In the book, Theophrastus described plants by their uses, and attempted a Taxonomy (biology), biological clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
