Atrichornis Clamosus
The noisy scrubbird (''Atrichornis clamosus'') is a species of bird in the family Atrichornithidae. It is endemic to the coastal heaths of south-western Australia (east of Albany). Description The noisy scrubbird features a dark brown coloured back, rust-like coloured wings and a speckled chestnut colored breast region with a grey-brown or pink bill and brown or silver legs and feet. They vary from 19–23 cm. in length and 25-58 grams. The males are distinguished from the females by exhibiting a black triangle on their throat . They are closely related to the lyrebird, having only evolutionarily separated from them approximately 30-35 million years ago. They prefer feeding upon small invertebrates, such as ants and beetles, in the extremely dense understory and vegetative cover that only occurs after environmental damages. Distribution The noisy scrubbird is one of Australia's rarest birds. It was presumed extinct until a population was discovered at Two Peoples Bay, ea ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist who published monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould (illustrator), Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. Because of his 1840s seven-volume series ''The Birds of Australia (Gould), The Birds of Australia'' and its updates he has been considered the father of bird study in Australia, and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life John Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained ...

Endangered Species (IUCN Status)
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively. IUCN Red List The IUCN Red List is a list of species which have been assessed according to a system of assigning a global conservation status. According to the latest system used by the IUCN, a species can be "Data Deficient" (DD) species – species for which more data and assessment is required before their situation may be determined – as well species comprehensively assessed by the IUCN's species assessment process. A species can be " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...

Endemic Birds Of Southwest Australia
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Atrichornis
Scrubbirds are shy, secretive, ground-dwelling birds of the family Atrichornithidae. There are just two species. The rufous scrubbird is rare and very restricted in its range, and the noisy scrubbird is so rare that until 1961 it was thought to be extinct. Both are native to Australia. The scrubbird family is ancient and is understood to be most closely related to the lyrebirds, and probably also the bowerbirds and treecreepers. All four families originated with the great corvid radiation of the Australia-New Guinea region. The population of the noisy scrubbird was estimated at 40 to 45 birds in 1962. Conservation efforts succeeded in increasing the population to around 400 birds by the mid-1980s, and they have subsequently been reintroduced to several sites, but remain endangered. As of 2002, the population had recovered to around 1,200 birds. Description Birds of both species are about the same size as a common starling (roughly 20 cm long) and cryptically colour ...

Translocations
In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes "balanced" and "unbalanced" translocation, with three main types: "reciprocal", "nonreciprocal" and "Robertsonian" translocation. Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes. Two detached fragments of two different chromosomes are switched. Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" and blends together homogeneously. Each type of chromosomal translocation can result in disorders for growth, function and the development of an individuals body, often resulting from a change in their genome. A gene fusion may be created when the translocation joins two otherwise-separated genes. It is detected on cytogenetics or a karyotype of affected cells. Translocations can be balanced ...

Forest Dieback
Forest dieback (also "", a German loan word, ) is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or conditions like acid rain, drought, and more. These episodes can have disastrous consequences such as reduced resiliency of the ecosystem, disappearing important symbiotic relationships and thresholds. Some tipping points for major climate change forecast in the next century are directly related to forest diebacks. Definition Forest dieback refers to the phenomenon of a stand of trees losing health and dying without an obvious cause. This condition is also known as forest decline, forest damage, canopy level dieback, and stand level dieback. This usually affects individual species of trees, but can also affect multiple species. Dieback is an episodic event and may take on many locations and shapes. It can be along the perimeter, at specific elevations, or dispersed throughout the forest ecosystem. Forest dieback present ...

Phytophthora Cinnamomi
''Phytophthora cinnamomi'', also known as cinnamon fungus, is a soil-borne water mould that produces an infection which causes a condition in plants variously called "dieback", "root rot", or (in certain '' Castanea'' species), "ink disease". Once infected soil or water is introduced, the organism can spread rapidly throughout an environment. An infestation can lead to the illness, death, and possible eradication of vulnerable plants, as well as habitat reduction for animals. An outbreak can be challenging to recognize and can inflict irreversible harm to ecosystems. The plant pathogen is one of the world's most invasive species and is present in over 70 countries around the world. Distribution and hosts ''Phytophythora cinnamomi'' is distributed worldwide and can infect a diverse range of hosts, including club mosses, ferns, cycads, conifers, cord rushes, grasses, lilies and a large number of species from many dicotyledonous families, and is included in the Invasive Spe ...

Margaret River
The Margaret River is a river in southwest Australia, southwest Western Australia. In a small catchment, it is the eponym of the town and tourist region of Margaret River, Western Australia, Margaret River. The river arises from a catchment of just 40 square kilometres in the Whicher Range. Ombak tujuh is a "big-wave" spot. The middle reaches pass through land cleared for agriculture, especially viticulture. There is a weir across the river just above the town. The mouth of the river is a small estuary, closed to the ocean by a sandbar that opens only seasonally. Margaret River is presumed to be named after Margaret Wyche, cousin of John Bussell, John Garrett Bussell (founder of Busselton, Western Australia, Busselton) in 1832.

Ellensbrook
Ellensbrook is a heritage-listed property in Leeuwin-Naturaliste National Park in the locality of Yebble, Western Australia near Margaret River. Also known as Ellensbrook House or Ellensbrook Homestead, the property is managed by the National Trust of Western Australia. History The site where Ellensbrook is located was historically a Noongar camping ground named ''Mokidup'', close to the sacred site of Meekadarribee Cave. In 1857, settlers Ellen and Alfred Bussell decided to build a new home on the site. The location was desirable due to its protection from storms, supply of fresh water, and the fertility of the soil. The homestead was built in stages over several decades using the labour of ticket-of-leave convicts, sailors who had deserted, and the local Noongar people, and was named after Ellen Bussell. While Alfred and Ellen moved away from Ellensbrook in 1865, the Bussell family remained involved. Their eldest daughter Fanny managed the property from 1871 to 1877, ex ...
