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 army, British and Indian army, 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 Tasmania, Hydro-Electric Commission of Tasmania as a surveyor. Although he had no formal training in botany, Morris's interest and talent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunbridge Wells
Royal Tunbridge Wells (formerly, until 1909, and still commonly 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 High Weald, whose sandstone geology is exemplified by the rock formation High Rocks. The town was a spa in the Restoration and a fashionable resort in the mid-1700s under 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 prefix "Royal" was granted to it in 1909 by King Edward VII; it is one of only three towns in England with the title. The town had a population of 59,947 in 2016, and is the administrative centre of Tunbridge Wells Borough and in the parliamentary constituency of Tunbridge Wells.

Weed
A weed is a plant considered undesirable in a particular situation, growing where it conflicts with human preferences, needs, or goals.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. Plants with characteristics that make them hazardous, aesthetically unappealing, difficult to control in managed environments, or otherwise unwanted in agriculture, farm land, Orchard, orchards, gardens, lawns, Park, parks, recreational spaces, residential and industrial areas, may all be considered weeds.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 presence of weeds in fields used to grow crops may cause major losses in yields. Invasive species, plants introduced to an environment where their presence negatively impacts the overall functioning and biodiversity of the ecosystem, may also sometime ...

Forensics
Forensic science combines principles of law and science to investigate criminal activity. Through crime scene investigations and laboratory analysis, forensic scientists are able to link suspects to evidence. An example is determining the time and cause of death through autopsies. This evidence can then be used for proof towards a crime. Forensic science, often confused with criminalistics, is the application of science principles and methods to support legal decision-making in matters of criminal and civil law. During criminal investigation in particular, it is governed by the legal standards of admissible evidence and criminal procedure. It is a broad field utilizing numerous practices such as the analysis of DNA, fingerprints, bloodstain patterns, firearms, ballistics, toxicology, microscopy, and fire debris analysis. Forensic scientists collect, preserve, and analyze evidence during the course of an investigation. While some forensic scientists travel to the scene of t ...

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. 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 quarantines applied throughout the world during the COVID-19 pande ...

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 region of Tasmania. The locality is about south-west of the city 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 Pipeline Tra ...

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 or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists. Modern tools include single or multi-access identification keys, which can be printed or computer-assisted. 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 identify 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 particul ...

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 taxonomy (biology), taxonomy. Plant taxonomy is concerned with grouping and classifying plants; Botany, 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'' (''ICNafp''), 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). Botanical nomenclature is indep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocotyledon
Monocotyledons (), commonly referred to as monocots, ( Lilianae '' sensu'' Chase & Reveal) are flowering plants whose seeds contain only one embryonic leaf, or cotyledon. A monocot taxon has been in use for several decades, but with various ranks and under several different names. The APG IV system recognises its monophyly but does not assign it to a taxonomic rank, and instead uses the term "monocots" to refer to the group. Monocotyledons are contrasted with the dicotyledons, which have two cotyledons. Unlike the monocots however, the dicots are not monophyletic and the two cotyledons are instead the ancestral characteristic of all flowering plants. Botanists now classify dicots into the eudicots ("true dicots") and several basal lineages from which the monocots emerged. The monocots are extremely important economically, culturally, and ecologically, and make up a majority of plant biomass used in agriculture. Common crops such as dates, onions, garlic, rice, wheat, maize, ... [...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 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 ed. 2005. Print. p. 595. As of 2002, Pinophyta contained seven families, 60 to 65 genera, and more than 600 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 notably ...
