Albert Morris (other)
Albert Morris (13 August 1886 in Bridgetown, South Australia – 9 January 1939, Broken Hill New South Wales) was an acclaimed Australian botanist, landscaper, ecologist, conservationist and developer of arid-zone revegetation techniques that featurenatural regeneration Morris is particularly celebrated for his decisive role in the development of the Broken Hill regeneration area, a pioneering arid-zone natural regeneration project. The regeneration area project exhibited standards and principles characteristic of the contemporary environmental repair practice, ecological restoration. The work of Albert Morris, Margaret Morris and their restoration colleagues significantly influenced the development of New South Wales government soil erosion management policies in the 1940s.

Assay
An assay is an investigative (analytic) procedure in laboratory medicine, mining, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or functional activity of a target entity. The measured entity is often called the analyte, the measurand, or the target of the assay. The analyte can be a drug, biochemical substance, chemical element or compound, or cell in an organism or organic sample. An assay usually aims to measure an analyte's intensive property and express it in the relevant measurement unit (e.g. molarity, density, functional activity in enzyme international units, degree of effect in comparison to a standard, etc.). If the assay involves exogenous reactants (the reagents), then their quantities are kept fixed (or in excess) so that the quantity and quality of the target are the only limiting factors. The difference in the assay outcome is used to deduce the unknown quality or quantity o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germination
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or cone after the union of male and female reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Some plants produce varying numbers of seeds that lack embryos; these are empty seeds which never germinate. Dormant seeds are viable seeds that do ...

Forbs
A forb or phorb is an herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in biology and in vegetation ecology, especially in relation to grasslands and understory. Typically these are dicots without woody stems. Etymology The word "forb" is derived from Greek ''phorbḗ'' (), meaning "pasture" or "fodder". The Hellenic spelling "phorb" is sometimes used, and in older usage this sometimes includes graminids and other plants currently not regarded as forbs. Guilds Forbs are members of a guilda group of plant species with broadly similar growth form. In certain contexts in ecology, guild membership may often be more important than the taxonomic relationships between organisms. In informal classification In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers, distinguishing them from other categories such as grasses, sedges, shrubs, and trees. Some examples of forbs are clovers, sun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thistle Harris
Thistle Yolette Harris (29 July 1902 – 5 July 1990), also known as Thistle Stead, was an Australian botany, botanist, educator, author and conservation movement, conservationist. Biography She was one of three daughters born to Charles Thomas Harris and Illma Richardson Harris (''née'' Rokes). She was educated at Redlands School SCECGS Redlands, Cremorne, New South Wales, Cremorne, where she was taught by the English teacher, Constance Le Plastrier (1864–1938), who was a member of the Naturalists Society of New South Wales and co-author of ''Botany for Australian Students'' (1916), and helped foster Harris' interest in native plants.Walter, J. (2009), pp.18-23 Harris died in 1990 at a nursing home in Summer Hill, New South Wales. Education Harris studied botany at the University of Sydney, graduating with a degree in botany in 1924 followed by a diploma of education in 1925 from Sydney Teachers' College, Sydney Teachers College.

State Herbarium Of South Australia
The State Herbarium of South Australia, sometimes called the South Australian Herbarium, and having the herbarium code, AD, is located in Adelaide, South Australia. It is one of several State and Commonwealth herbaria in Australia. The Department for Environment and Water is the state agency which is responsible for the Herbarium, but the Board of the Botanic Gardens and State Herbarium (established by an Act of Parliament, most recently the ''Botanic Gardens and State Herbarium Act 1978'') is charged with its establishment and maintenance. The herbarium is responsible for Electronic Flora of South Australia. It also produces the journal, ''Swainsona'' (formerly ''Journal of the Adelaide Botanic Gardens''). History In 1954 the State Herbarium of South Australia was founded as part of the Adelaide Botanic Garden. The first flora collection of the state was produced by Richard Schomburgk (1811–1891) in 1875. The State Herbarium's collections include collections of Ralph Tat ...

Yunta, South Australia
Yunta is a town and locality in the Australian state of South Australia located in the state's east about north-east of the state capital of Adelaide. It is a service centre supporting both the local area and travellers passing through on the Barrier Highway. It lies south west of Broken Hill and north east of Peterborough. History Yanta was an early spelling. In 1866 the district was known as part of the Tattawappa and Yanta Run. Yunta township was established in 1887 after the discovery of gold at the nearby diggings at Teetulpa and Waukaringa, when more than 5,000 miners made their way through here. In the early 1890s the village was a busy railway town on the Adelaide to Broken Hill line. From 1934 Yunta was the base for the famed outback trucking and mail contractor Harry Ding. Today Yunta is a small service centre for travellers and the surrounding properties. Yunta also provides an alternate route to the Flinders Ranges and beyond.

Ecosystems
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. Interna ...

Flora
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field Trips
A field trip or excursion is a journey by a group of people to a place away from their normal environment. When done for students, as it happens in several school systems, it is also known as school trip in the United Kingdom, UK, Australia, New Zealand and Bangladesh, and school tour in Ireland. A 2022 study, which used randomized controlled trial data, found that culturally enriching field trips led students to show a greater interest in arts, greater tolerance for people with different views, and boosted their educational outcomes. Overview The purpose of the field trip is usually ''observation'' for education, non-experimental research or to provide students with experiences outside their everyday activities, such as going camping with teachers and their classmates. The aim of this research is to observe the subject in its natural state and possibly collect samples. It is seen that more-advantaged children may have already experienced cultural institutions outside of scho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
