Cornelius Herman Muller
Cornelius Herman ("Neil") Muller, born Müller, (July 22, 1909 – January 26, 1997) was an American botanist and ecologist who pioneered the study of allelopathy and oak classification. Personal life Müller was born in Collinsville, Illinois, but moved at an early age to Cuero, Texas and was educated there. He was graduated with a BA in botany from the University of Texas in 1932, and an MA from the same institution in 1933. He first married Mary Elizabeth Taylor, but they divorced in 1936; he changed his name to Muller in the following year. After graduating from the University of Illinois in 1938 with a Ph.D. in botany, Muller worked for the Illinois Natural History Survey for one year and then for the US Department of Agriculture in various capacities from 1938 to 1945. Summers were usually spent on plant collecting trips to Mexico, the Southwest, and the southern United States. His work focused on vegetation studies in Texas and Mexico and most prominently on oaks.

Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Adjunct Professor
An adjunct professor is a type of academic appointment in higher education who does not work at the establishment full-time. The terms of this appointment and the job security of the tenure vary in different parts of the world, however the general definition is agreed upon. The term "Adjuncting" is a way of referring to a bona-fide part-time faculty member who has worked in an adjunct position for an institution of higher education. Terminology They may also be called an adjunct lecturer, adjunct instructor, or adjunct faculty. Collectively, they may be referred to as contingent academic labor. The rank of sessional lecturer in Canadian universities is similar to the US concept. North America In the United States, an adjunct is, in most cases, a non-tenure-track faculty member. However, it can also be a scholar or teacher whose primary employer is not the school or department with which they have adjunct status. Adjunct professors make up the majority of instructors in high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably '' Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. ...

Central American
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' voyages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycopersicon
''Lycopersicon'' was a genus in the flowering plant family Solanaceae (the nightshades and relatives). It contained about 13 species in the tomato group of nightshades. First removed from the genus ''Solanum'' by Philip Miller in 1754, its removal leaves the latter genus paraphyletic, so modern botanists generally accept the names in ''Solanum''. The name ''Lycopersicon'' (from Greek ''λυκοπέρσικον'' meaning "wolf peach") is still used by gardeners, farmers, and seed companies. Collectively, the species in this group apart from the common cultivated plant are called wild tomatoes. Cladistic analysis of DNA sequence data confirms ''Lycopersicon'' as a clade that is part of a lineage of nightshades also including the potato (''S. tuberosum''). If it is desired to continue use of ''Lycopersicon'', it can be held as a section inside the potato-tomato subgenus whose name has to be determined in accordance with the ICBN.Solanaceae Source 008br>Phylogeny Retrieved 2008-OCT- ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
