Dennis Ivor Morris
Dennis Ivor Morris (16 May 1924–27 July 2005) was a British-born Australian botanist. Early life and career Dennis Ivor Morris, born on 16 May 1924, in Tunbridge Wells, England, had his formative education at the Worshipful Company of Skinners School. He received a comprehensive education, displaying a vast knowledge that spanned various fields including literature, history, and science. Morris's early adulthood was marked by his service in the British and Indian armies from 1942 to 1947, where he reached the rank of Captain. After his military service, he engaged in forestry and farm work in England. In 1950, he moved to Australia, initially working on a sheep station in western Queensland. This was followed by a surveying job in British Columbia, Canada, before returning to Australia in 1952 to join the Hydro-Electric Commission of Tasmania as a surveyor. Although he had no formal training in botany, Morris's interest and talent in the subject led him to a successful ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunbridge Wells
Royal Tunbridge Wells is a town in Kent, England, southeast of central London. It lies close to the border with East Sussex on the northern edge of the Weald, High Weald, whose sandstone geology is exemplified by the rock formation High Rocks. The town was a spa in the Restoration (England), Restoration and a fashionable resort in the mid-1700s under Richard (Beau) Nash, Beau Nash when the Pantiles, and its chalybeate spring, attracted visitors who wished to take the waters. Though its popularity as a spa town waned with the advent of sea bathing, the town still derives much of its income from tourism. The town has a population of around 56,500, and is the administrative centre of Tunbridge Wells (borough), Tunbridge Wells Borough and in the parliamentary constituency of Tunbridge Wells (UK Parliament constituency), Tunbridge Wells. History Iron Age Evidence suggests that Iron Age people farmed the fields and mined the iron-rich rocks in the Tunbridge Wells area, and excava ...

Weed
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. This introduces the concept of humans and their goals in a particular setting.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the aim is growing crops or pastures of a single species, or a mixture of a few desired species. In such environments, other plant species are considered undesirable and therefore a weed. Besides, some weeds have undesirable characteristics making them a plant pest in most human settings.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Spri ...

Forensics
Forensic science, also known as criminalistics, is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. Forensic science is a broad field that includes; DNA analysis, fingerprint analysis, blood stain pattern analysis, firearms examination and ballistics, tool mark analysis, serology, toxicology, hair and fiber analysis, entomology, questioned documents, anthropology, odontology, pathology, epidemiology, footwear and tire tread analysis, drug chemistry, paint and glass analysis, digital audio video and photo analysis. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. While some forensic scientists travel to the scene of the crime to collect the evidence themselves, others occupy a laboratory role, performing analysis on objects brought to them by other individuals.

Quarantine
A quarantine is a restriction on the movement of people, animals and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. Quarantine considerations are often one aspect of border control. The concept of quarantine has been known since biblical times, and is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive ...

Australian Quarantine And Inspection Service
The Australian Quarantine and Inspection Service was the Australian government agency responsible for enforcing Australian quarantine laws, as part of the Department of Agriculture. Following a period operating under the name DAFF Biosecurity, it has since been absorbed into divisions in the Department of Agriculture and Water Resources. Quarantine in Australia AQIS's import and export inspection and certification is essential to maintaining Australia's highly favourable animal, plant and human health status and access to export markets. Quarantine controls at Australia's borders minimise the risk of exotic pests and diseases to protect Australia's agriculture industries and environment. AQIS does this by specialist Federal law enforcement officers known as Quarantine & Exports Inspectors, or 'Quarantine Officers'. History On 30 March 1908, the Commonwealth Quarantine service came into operation and took over quarantine stations in every Australian state, as allowed in sect ...

Fern Tree, Tasmania
Fern Tree is a rural / residential locality in the local government areas (LGA) of Hobart (64%) and Kingborough (36%) in the Hobart LGA region of Tasmania. The locality is about south-west of the town of Hobart. The 2016 census recorded a population of 726 for the state suburb of Fern Tree. It is an outlying suburb of Hobart. The name Fern Tree is adapted from the common name of the plant ''Dicksonia antarctica'' (Tasmanian tree fern), which grows abundantly in the area. Set beneath Mount Wellington, whose summit is at 1270 metres above sea level, Fern Tree is 9 km by road from Hobart's central business district. History Fern Tree was gazetted as a locality in 1963. It was originally a postal station on the road to the Huon Valley, and later the site through which Hobart's water supply passed. Settled from the mid 19th century, Fern Tree and its environs have always been a major recreational area for Hobart residents. Its many walking tracks (most notably the Pipelin ...

Virtual Herbarium
In botany, a virtual herbarium is a herbarium in a digitized form. That is, it concerns a collection of digital images of preserved plants or plant parts. Virtual herbaria often are established to improve availability of specimens to a wider audience. However, there are digital herbaria that are not suitable for internet access because of the high resolution of scans and resulting large file sizes (several hundred megabytes per file). Additional information about each specimen, such as the location, the collector, and the botanical name are attached to every specimen. Frequently, further details such as related species and growth requirements are mentioned. Specimen imaging The standard hardware used for herbarium specimen imaging is the "HerbScan" scanner. It is an inverted flat-bed scanner which raises the specimen up to the scanning surface. This technology was developed because it is standard practice to never turn a herbarium specimen upside-down. Alternatively, some herbar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Identification
In biology, determination is the process of matching a specimen of an organism to a known taxon, for example identifying a plant. The term is also used in cellular biology, where it means the act of the differentiation of stem cells becoming fixed. Various methods are used, for example single or multi-access identification keys. Overview The need to identify which plant is which has existed for time immemorial. The ability depends to a large extent on what criteria and whose system is used. Determination now relies on modern taxonomy to define the identify of organisms. Taxonomy is the branch of biology which deals with identity, nomenclature and classification. The term was first coined in 1813 by Swiss botanist Augustin Pyramus de Candolle. Carl Linnaeus, who began modern taxonomy, used the term 'systematics' himself. Determination then requires comparisons of certain characteristics and then assigning a particular specimen to a known taxonomic group, hopefully ultimately ...

Tasmanian Herbarium
The Tasmanian Herbarium is a herbarium in Hobart, Tasmania, Australia. Its Index Herbariorum code is HO. It is a part of the Tasmanian Museum and Art Gallery. The earliest plant samples in the herbarium's collection date from early European exploration of Tasmania. These include specimens collected in the 1792 voyage to the island of Bruny d'Entrecasteaux and those collected by Robert Brown in the first decade of the 19th Century. Since 1977 the herbarium has been located on the Sandy Bay campus of the University of Tasmania.

Botanical Nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from Alpha taxonomy, taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Carl Linnaeus, Linnaeus' ''Species Plantarum'' of 1753. Botanical nomenclature is governed by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN''), which replaces the ''International Code of Botanical Nomenclature'' (''ICBN''). Fossil plants are also covered by the code of nomenclature. Within the limits set by that code there is another set of rules, the ''International Code of Nomenclature for Cultivated Plants, International Code of Nomenclature for Cultivated Plants (ICNCP)'' which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen). History and scope Botanical nomenclature has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocotyledon
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided; the rest of the flowering plants have two cotyledons and are classified as dicotyledons, or dicots. Monocotyledons have almost always been recognized as a group, but with various taxonomic ranks and under several different names. The APG III system of 2009 recognises a clade called "monocots" but does not assign it to a taxonomic rank. The monocotyledons include about 60,000 species, about a quarter of all angiosperms. The largest family in this group (and in the flowering plants as a whole) by number of species are the orchids (family Orchidaceae), with more than 20,000 species. About half as many species belong to the true grasses ( Poaceae), which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...
