Albizia Canescens
''Albizia canescens'', commonly known as Belmont siris, is a species of ''Albizia'', endemic to Northern Australia. Description While superficially similar to the closely related '' A. lebbek'', which has an overlapping native range, ''A. canescens'' can be distinguished by several features. The crown of ''A. canescens'' is more open than that of ''A. lebbeck'', and the foliage glaucous rather than dark green. Both the flowers and pods of ''A. canescens'' are small and inconspicuous compared to the showy, globular flowers and large pods of ''A. lebbeck'', and the bark of ''A. canescens'' is fissured, corky and more fire resistant than the tessellated bark of ''A. lebbek''.Lowry, J.B. 2008 "Trees for Wood and Animal Production in Northern Australia". Rural Industries Research and Development Corporation, Indooroopilly, Queensland The growth habit of the species is variable, with individuals able to persist and fruit as either a large single stemmed tree to 10 metres, or as a ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Top End
The Top End of Australia's Northern Territory is a geographical region encompassing the northernmost section of the Northern Territory, which aside from the Cape York Peninsula is the northernmost part of the Australian continent. It covers a rather vaguely defined area of about 245,000 km² (95,000 sq mi) behind the northern coast from the Northern Territory capital of Darwin across to Arnhem Land with the Indian Ocean on the west, the Arafura Sea to the north, and the Gulf of Carpentaria to the east, and with the almost waterless semi-arid interior of Australia to the south, beyond the huge Kakadu National Park. The Top End contains both of the Territory's cities and one of its major towns, Darwin, Palmerston and Katherine. The well-known town of Alice Springs is located further south, in the arid southern part of the Northern Territory, sometimes referred to by Australians as the Red Centre. The landscape is relatively flat with river floodplains and grasslands with eucaly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Queensland
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] |
Forages
Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include ''resources'', the elements necessary for survival and reproduction which have a l ...

Psychoactive
A psychoactive drug, psychopharmaceutical, psychoactive agent or psychotropic drug is a chemical substance, that changes functions of the nervous system, and results in alterations in perception, mood, consciousness, cognition or behavior. These substances may be used medically, recreationally or spiritually to a. Purposefully improve one’s perceived performance b. Alter one's consciousness (such as with entheogens for ritual, spiritual or shamanic purposes) or c. For research. Some categories of psychoactive drugs - which are believed, by some, to have therapeutic value - may be prescribed by some physicians and other healthcare practitioners. Examples of medication categories that may contain potentially beneficial psychoactive drugs include, but are not limited to: # Anesthetics # Analgesics # Anticonvulsants # Anti-Parkinson’s medications # Medications used to treat Neuropsychiatric Disorders a. Antidepressants b. Anxiolytics c. Antipsychotics d. Sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Gum
Natural gums are polysaccharides of natural origin, capable of causing a large increase in a solution's viscosity, even at small concentrations. They are mostly botanical gums, found in the woody elements of plants or in seed coatings. Human uses They are used in the food industry as thickening agents, gelling agents, emulsifying agents, and stabilizers, and in other industrial adhesives, binding agents, crystal inhibitors, clarifying agents, encapsulating agents, flocculating agents, swelling agents, foam stabilizers, etc. When consumed by humans, many of these gums are fermented by the microbes that inhabit the lower gastrointestinal tract (microbiome) and may influence the ecology and functions of these microscopic communities. Examples Natural gums can be classified according to their origin. They can also be classified as uncharged or ionic polymers (polyelectrolytes). Examples include (with E number E numbers ("E" stands for "Europe") are codes for substances used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Australians
Indigenous Australians or Australian First Nations are people with familial heritage from, and membership in, the ethnic groups that lived in Australia before British colonisation. They consist of two distinct groups: the Aboriginal peoples of the Australian mainland and Tasmania, and the Torres Strait Islander peoples from the seas between Queensland and Papua New Guinea. The term Aboriginal and Torres Strait Islander peoples or the person's specific cultural group, is often preferred, though the terms First Nations of Australia, First Peoples of Australia and First Australians are also increasingly common; 812,728 people self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these indigenous Australians, 91.4% identified as Aboriginal; 4.2% identified as Torres Strait Islander; while 4.4% identified with both groups.

Agroforestry
Agroforestry is a land use management system in which trees or shrubs are grown around or among crops or pastureland. Trees produce a wide range of useful and marketable products from fruits/nuts, medicines, wood products, etc. This intentional combination of agriculture and forestry has multiple benefits, such as greatly enhanced yields from staple food crops, enhanced farmer livelihoods from income generation, increased biodiversity, improved soil structure and health, reduced erosion, and carbon sequestration. Agroforestry practices are highly beneficial in the tropics, especially in subsistence smallholdings in sub-Saharan Africa and have been found to be beneficial in Europe and the United States. Agroforestry shares principles with intercropping but can also involve much more complex multi-strata agroforests containing hundreds of species. Agroforestry can also utilise nitrogen-fixing plants such as legumes to restore soil nitrogen fertility. The nitrogen-fixing plants can ...

Cattle Station
In Australia and New Zealand, a cattle station is a large farm ( station is equivalent to the American ranch), the main activity of which is the rearing of cattle. The owner of a cattle station is called a '' grazier''. The largest cattle station in the world is Anna Creek Station in South Australia, which covers an area of . Improvements Each station has a homestead where the property owner or the manager lives. Nearby cottages or staff quarters provide housing for the employees. Storage sheds and cattle yards are also sited near the homestead. Other structures depend on the size and location of the station. Isolated stations will have a mechanic's workshop, schoolroom, a small general store to supply essentials, and possibly an entertainment or bar area for the owners and staff. Water may be supplied from a river, bores or dams, in conjunction with rainwater tanks. Nowadays, if rural mains power is not connected, electricity is typically provided by a generator, although sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
