Botany is the scientific study of plants, including their physiology, structure, genetics, ecology, distribution, classification, and economic importance.

"Traditionally, botany included the study of fungi, algae and viruses. Botany covers a wide range of scientific disciplines including structure, growth, reproduction, metabolism, development, diseases, chemical properties, and evolutionary relationships among taxonomic groups. Botany began with early human efforts to identify edible, medicinal and poisonous plants, making it one of the oldest branches of science. Today botanists study about 400,000 species of living organisms."[1]

Dominant group

[edit | edit source]
Main resource: Dominant group

Examples from primary sources are to be used to prove or disprove each hypothesis. These can be collected per subject or in general.

  1. Accident hypothesis: dominant group is an accident of whatever processes are operating.
  2. Artifact hypothesis: dominant group may be an artifact of human endeavor or may have preceded humanity.
  3. Association hypothesis: dominant group is associated in some way with the original research.
  4. Bad group hypothesis: dominant group is the group that engages in discrimination, abuse, punishment, and additional criminal activity against other groups. It often has an unfair advantage and uses it to express monopolistic practices.
  5. Control group hypothesis: there is a control group that can be used to study dominant group.
  6. Entity hypothesis: dominant group is an entity within each field where a primary author of original research uses the term.
  7. Evolution hypothesis: dominant group is a product of evolutionary processes, such groups are the evolutionary process, produce evolutionary processes, or are independent of evolutionary processes.
  8. Identifier hypothesis: dominant group is an identifier used by primary source authors of original research to identify an observation in the process of analysis.
  9. Importance hypothesis: dominant group signifies original research results that usually need to be explained by theory and interpretation of experiments.
  10. Indicator hypothesis: dominant group may be an indicator of something as yet not understood by the primary author of original research.
  11. Influence hypothesis: dominant group is included in a primary source article containing original research to indicate influence or an influential phenomenon.
  12. Interest hypothesis: dominant group is a theoretical entity used by scholarly authors of primary sources for phenomena of interest.
  13. Metadefinition hypothesis: all uses of dominant group by all primary source authors of original research are included in the metadefinition for dominant group.
  14. Null hypothesis: there is no significant or special meaning of dominant group in any sentence or figure caption in any refereed journal article.
  15. Object hypothesis: dominant group is an object within each field where a primary author of original research uses the term.
  16. Obvious hypothesis: the only meaning of dominant group is the one found in Mosby's Medical Dictionary.
  17. Original research hypothesis: dominant group is included in a primary source article by the author to indicate that the article contains original research.
  18. Primordial hypothesis: dominant group is a primordial concept inherent to humans such that every language or other form of communication no matter how old or whether extinct, on the verge of extinction, or not, has at least a synonym for dominant group.
  19. Purpose hypothesis: dominant group is written into articles by authors for a purpose.
  20. Regional hypothesis: dominant group, when it occurs, is only a manifestation of the limitations within a region. Variation of those limitations may result in the loss of a dominant group with the eventual appearance of a new one or none at all.
  21. Source hypothesis: dominant group is a source within each field where a primary author of original research uses the term.
  22. Term hypothesis: dominant group is a significant term that may require a 'rigorous definition' or application and verification of an empirical definition.

Plants

[edit | edit source]
Main resource: Plants

Def. "[a]n organism of the kingdom Plantae; now specifically, a living organism of the Embryophyta (land plants) or of the Chlorophyta (green algae), a eukaryote that includes double-membraned chloroplasts in its cells containing chlorophyll a and b, or any organism closely related to such an organism"[2] is called a plant.

Def. " a multicellular eukaryote that includes chloroplasts in its cells, which have a cell wall"[2] is called a plant.

"Statistical analyses indicate that the Phanerozoic history of vascular land plants (tracheophytes) may be interpreted in terms of the successive radiations of four major plant groups, each characterized by a common morphological and/or reproductive grade. Following initial invasion of the land, the diversification of each group coincides with a decline in species numbers of the previously dominant group."[3]

Botany

[edit | edit source]
Main resource: Botany

Def. "[t]he scientific study of plants, ... [t]ypically those disciplines that involve the whole plant"[4] is called botany.

Usage notes:

"The scientific definition of what organisms should be considered plants changed dramatically during the 20th century. Bacteria, algae, and fungi are no longer considered plants by those who study them. Many textbooks do not reflect the most current thinking on classification."[2]

Dominant species:

"[I]n any limited country, the species which is most common, that is abound most in individuals, and the species which are most widely diffused within their country (and this is a different consideration from wide range, and to a certain extent from commonness), often give rise to varieties sufficiently well-marked to have been recorded in botanical works. Hence it is the most flourishing, or as they may be called, the dominant species -- those which range widely over the world, are the most diffused in their own country, and are the most numerous in individuals, -- which oftenest produce well-marked varieties, or, as I consider them, incipient species."[5]

Entities

[edit | edit source]
Main resource: Dominant group/Entities

"In other words, those with significant cultural capital – intellectuals, artists, professors, etc. - were part of the field of power and exercised some level of domination within society (by controlling the processes of cultural reproduction and its contents), but they were, within the dominant group, dominated by those with more economic capital."[6]

Agronomy

[edit | edit source]
Main resource: Agronomy

Def. "[t]he science of utilizing plants, animals and soils for food, fuel, feed, and fiber and more"[7] is called agronomy.

Def. "[t]he art or science of cultivating the ground, including the harvesting of crops, and the rearing and management of livestock; tillage; husbandry; farming"[8] is called agriculture.

"Annual broadleaf weeds (17 species) were clearly the dominant group under all tillage treatments, compared with the perennials (6 species) and annual grassy (4 species) weeds."[9]

"Regardless of year or treatment combination, values for each parameter (except ASIp) were nearly always lower for the dominated relative to intermediate and dominant plant group(s). For all parameters but ASIp, the application of either 165 or 330 kg N ha-1 often decreased the dominant group/dominanted group mean ratio in both years for either plant density."[10]

"In all, 75.6% of the trees fall into the dominant group which has only 12 species, far more than that of park and institutional forests (Table 2)."[11]

Angiosperms

[edit | edit source]
Main resources: Botany/Angiosperms and Angiosperms

"Flowering plants, or angiosperms, are presently the most dominant group of terrestrial autotrophs."[12]

From 1880 is the following: “The Plant life of this Period was of a very varied and luxuriant character, and the Angiosperms had now become the dominant group.”[13]

"Today, with approximately 300,000 species distributed worldwide, the angiosperms are the dominant group of vascular plants in terrestrial ecosystems."[14]

Bryology

[edit | edit source]
Main resource: Bryology

Def. "[t]he study of bryophytes (non-vascular plants including mosses and liverworts)"[15] is called bryology.

"The Lejeuneaceae, with about 1000 species in about 90 genera, is the largest family of liverworts (Marchantiophyta) (Wilson et al., 2007) and the most dominant group of the epiphyllous flora (Gradstein, 1997; Zhu & So, 2001)."[16]

"Liverworts were the dominant group in all localities and habitats, accounting for about two-thirds of the species."[17]

"Yet it is these leafy members which make up the dominant group of the Hepaticae, since they comprise more than 85 per cent of the total (8500 species)."[18]

Dendrology

[edit | edit source]
Main resource: Dendrology

Notation: let the symbol ECG stand for ecological-coenotic groups.

"We have suggested assigning a dominant group in ground vegetation according to the regional probabilistic tables of correspondence between forest site index and dominant ECG (constructed for different dominant tree species)."[19]

"In terms of trophism index the dominant group are plants of rich soils (279 species)."[20]

Dominant classification

[edit | edit source]
Main resource: Dominant group/Classification

Scientific classification in botany is a method by which botanists group and categorize organisms by biological type, such as genus or species. Biological classification is a form of scientific taxonomy. Modern taxonomy is rooted in the work of Carolus Linnaeus, who grouped species according to shared physical characteristics. These groupings have since been revised to improve consistency with the Darwinian principle of common descent. While scientists do not always agree on how to classify organisms, molecular phylogenetics, which uses DNA sequences as data, has driven many recent revisions along more efficient, evolutionary lines and is likely to continue to do so. Botanical classification belongs to the science of plant systematics. The dominant classification system is called the Linnaean taxonomy. It includes ranks and binomial nomenclature. The classification, taxonomy, and nomenclature of botanical organisms is administered by the International Code of Nomenclature for algae, fungi, and plants (ICN).[21][22] Bold added.

"Our results showed that: (1) Dai people of Xishuangbanna used a wide range of wetland plants, including 46 families and 102 species, of which hygrophytes (helophytes) are the dominant group."[25]

"Ethnocide is when a dominant political group attempts to purposely put an end to a people’s traditional way of life. Linguicide (linguistic genocide) is when such a dominant group tries to extinguish the language of a minority group, say by punishing anyone caught speaking it."[26] "What about the “science” of these tiny undiscovered endangered languages? Does that kind of “primitive” ethnoscience have anything to teach us? The main examples that are quoted in the responses to this question have to do with ethnobotany and ethnomedicine."[26]

"The coconut family is the dominant group of palms in South America, with specialized tribal and generic characters, and hundreds of wild species, but is not represented in the Old World tropics."[27]

Lichenology

[edit | edit source]

"Alectorioid lichens are the dominant group of epiphytic lichens in boreal forests."[35]

"The dominant group of lichens in tropical rain forests are crustose microlichens, a highly diverse assemblage that lacks detailed taxonomic and ecological studies, among them the families Graphidaceae and Thelotremataceae (Wirth and Hale 1963, 1978; Hale 1974, 1978"[36]

Paleobotany

[edit | edit source]
Main resource: Paleobotany

"The groups could then be arranged from the dominant group (first rank) to the least common group (fifth rank)."[37]

"The dominant group in the Palaeozoic microplankton is the Acritarcha."[38]

"Pteridophyta is the second dominant group."[39]

"The angiosperms are both the dominant group of land plants and by far the most important plants for human use."[40]

Palynology

[edit | edit source]
Main resource: Palynology

"A palynological study on Miocene–Pleistocene sediments exposed at Surai Khola in central Nepal yields new information on vegetation and climate change over the last ∼11.5 Ma. [...] Pollen assemblages from the Surai Khola section suggest complex vegetation changes, of which the shift to C4 grass dominance was only one. [...] Grassland taxa (Gramineae and others) characterize this zone as the dominant group."[41]

The "palynological record from two shallow core holes (6611/09-U-01 and -02) from the Trøndelag Platform offshore mid-Norway [consist] of 750 m of Upper Permian and Lower Triassic sediments. The relatively homogeneous assemblages recovered from the Upper Permian deposits are dominated by gymnosperm pollen, mainly pteridosperms. At the base of the Griesbachian, numerous spore species appear in the record, leading to an increased diversity. The change at this boundary is also marked by the massive reduction of one group of pteridosperm pollen (Vittatina). Together with other typical Permian elements (e.g., Lueckisporites virkkiae), this group is rare but consistently present in the lower part of the Griesbachian, and it gradually disappears in its upper part. The distribution of other groups such as taeniate and non-taeniate bisaccate gymnosperm pollen (pteridosperms and conifers) shows no significant change across the boundary, whereas spores and other gymnosperm pollen increase in diversity and abundance. These changes coincide with the formational change between the Schuchert Dal Formation (Upper Permian) and the Wordie Creek Formation (Griesbachian) equivalents."[42]

"In contrast to the common claim that marine and terrestrial biota both suffered a mass extinction related to the Permian-Triassic boundary event, the studied material from the Norwegian midlatitudinal sites shows no evidence for destruction of plant ecosystems. The presence of diverse microfloras of Griesbachian age supports the idea that the climate in this area allowed most plants to survive the Permian-Triassic boundary event."[42]

"According to the data from mid-Norway as well as the previous records from East Greenland and the Barents Shelf, the widely accepted image of the lowermost Triassic flora, after which herbaceous lycopsids invaded the devastated terrestrial ecosystems and became the globally dominant group, has to be revised."[42]

Plant anatomy

[edit | edit source]
Main resources: Plants/Anatomy and Plant anatomy

"To date about 33 species belonging to 17 genera of fossil wood have been recorded from the Jurassic in China (Fig. 3, Table 1). They are mainly preserved as silicified type, which is predominant group of fossil preservation."[43]

"Coniferales: this is the dominant fossil wood group in the Jurassic of China ranging in age from Early to Late Jurassic."[43]

"Growth rings are well developed in these woods with wider early wood and narrow late wood, normally 1-2 tracheids wide and maximum 5-6 tracheids. These anatomical features may imply that the climate in western Liaoning was warm and humid during the Early Jurassic with seasonal variations: long spring and summer seasons and a shorter winter season. The megaplant assemblages in the Beipiao Formation (Zhang and Zheng, 1987) show that ferns are the dominant group in the assemblages, with diverse Cladophlebis foliages of larger fronds. The ferns were growing under the canopy of an arborescent forest dominated by conifers and ginkgoaleans, which are tolerant of a warm and humid climate. The fossil woods in the Beipiao Formation were dominated by conifers, which are the coal-forming plants during the Early Jurassic."[43]

Plant ecology

[edit | edit source]
Main resources: Ecology/Plants and Plant ecology

"It is no surprise that the data show the grass family (Poaceae) to be the dominant group, with nearly 200 exotic species in the western U.S. and 73 in the Sonoran Desert province. It is notable that species of Mediterranean origin are dominant in biomass in the Sonoran region (even though fewer in species than European or Eurasian weeds)."[44]

Plant genetics

"The way in which these genes interact with the dominant group 2 genes has yet to be determined."[45]

"From about 41 million ha represented (with a total of about 1,200 cultivars on the official list), about 145 cultivars (12%) belong to the dominant group (occupying at least 50% of the barley acreage)."[46]

"Bacteria are the most dominant group of this diversity which produce a wide range of products of industrial significance."[47]
