Medium Ground Finch
The medium ground finch (''Geospiza fortis'') is a species of bird in the family Thraupidae. It is endemic to the Galapagos Islands, Galápagos Islands. Its primary natural habitat is tropical shrubland. One of Darwin's finches, the species was the first which scientists have observed Evolution, evolving in real-time. Many studies and research have been conducted on medium ground finches: there are the most famous studies conducted by Charles Darwin and more recent studies conducted in relation to the changes revolving around the medium ground finches due to natural selection. Due to an increase in urbanization on the Galápagos Islands, droughts and climate change, character displacement, changes in the finch's habitat and range, inbreeding and nesting, parasites, and viruses, medium ground finches have gone through changes. Changes that have been observed are beak size, behavior in feeding, behavior in inbreeding, behaviors in nesting, antibody development and more. The changes ...

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 ...

Avipoxvirus
''Avipoxvirus'' (avian pox) is a genus of viruses within the family ''Poxviridae''. ''Poxviridae'' is the family of viruses which cause the afflicted organism to have poxes as a symptom. Poxviruses have generally large genomes, and other such examples include smallpox and monkeypox. Members of the genus ''Avipoxvirus'' infect specifically birds. Avipoxviruses are unable to complete their replication cycle in non-avian species. Although it is comparably slow-spreading, ''Avipoxvirus'' is known to cause symptoms like Cutaneous condition#Nodule, pustules lining the skin and diphtheria-like symptoms. These diphtheria-like symptoms might include diphtheric necrosis, necrotic membranes lining the mouth and the Respiratory tract#Upper respiratory tract, upper respiratory tract. Like other avian viruses, it can be transmitted through vectors mechanically such as through mosquitoes. There is no evidence that this virus can infect humans. ''Avipoxvirus'' is a virus that is brick-shaped and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philornis Downsi
''Philornis downsi'', also known as the avian vampire fly, is a species of fly (Diptera, Muscidae) that was first recorded in Trinidad and Brazil in the 1990s. It has been accidentally Introduced species, introduced to the Galapagos Islands (Ecuador). Adults of ''P. downsi'' feed on fruit. Eggs are laid in bird nests and hatch into parasitic larvae that reside in the nest material and emerge at night to feed both internally and externally on the blood and flesh of developing nestlings. The parasite causes significant mortality in Darwin's finch nestlings and threatens the survival of some rarer species such as the mangrove finch (''Camarhynchus heliobates'') and the medium tree finch (''C. pauper''). To protect the threatened finch populations, insecticide-laced cotton has been supplied as nesting material for the finches, with the results being highly successful in combating ''P. downsi'' infestations at a localized scale. Currently, Biological pest control agents, including ''C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is Australia’s principal public service broadcaster. It is funded primarily by grants from the federal government and is administered by a government-appointed board of directors. The ABC is a publicly-owned statutory organisation that is politically independent and accountable; for example, through its production of annual reports, and is bound by provisions contained within the Public Interest Disclosure Act 2013 and the Public Governance, Performance and Accountability Act 2013, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an Act of Federal Parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A ...

Tribulus Cistoides
''Tribulus cistoides'', also called wanglo (in Aruba), the Jamaican feverplant or puncture vine, is a species of flowering plant in the family Zygophyllaceae, which is widely distributed in tropical and subtropical regions. Habitat ''Tribulus cistoides'', known locally in Mexico as “Abrojo de tierra caliente” (thistle of the hot country), grows in Central, South, and the southern part of North America. It survives well in arid low land close to the shore and where sand or loose soil is present. This is also why it may survive in urban environments in or by the gutters of roads, as there may be loose soil nearby.Abbott, I., Abbott, L. K., & Grant, P. R. (1977).

Endemic
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 bec ...

Geospiza Conirostris
''Geospiza'' is a genus of bird in the tanager family Thraupidae. All species in the genus are endemic to the Galápagos Islands. Together with related genera, they are collectively known as Darwin's finches. Although in the past, they were classified in the bunting and American sparrow family Emberizidae, more recent studies have shown they belong in the tanager family. Taxonomy and species list The genus ''Geospiza'' was introduced in 1837 by the English ornithologist John Gould with the large ground finch as the type species. The genus name derives from the two Ancient Greek words (), meaning "earth", and (), a catch-all term for ''finch''-like birds. The member of the genus form part of a group collectively known as Darwin's finches. Although traditionally placed with the buntings and New World sparrows in the family Emberizidae, molecular phylogenetic studies have shown that Darwin's finches are members of the subfamily Coerebinae within the tanager family Thraupidae.

Geospiza Magnirostris
The large ground finch (''Geospiza magnirostris'') is a species of bird in the genus Geospiza. One of Darwin's finches, it is now placed in the tanager family Thraupidae and was formerly in the Emberizidae. It is the largest species of Darwin's finch. Description The large ground finch weighs about 27-39 g, and its length ranges slightly 15-16 cm. It is the largest species of Darwin's finch both in total size and size of beak. The feather and bill colors vary between males and females. The adult male is mostly black, with slightly browner wings and tail; the cloaca is white-streaked; the eyes are dark brown. It also has blackish legs. The tail is relatively short. An adult female has browner feathers compared to a male, sometimes with yellow-brown or grey outer edges; scaled patterns are found going up the body; most parts of the torso and the head are streaked with brown and pale yellow shades. Beak It has a large beak, having a thick base of lower mandibles and curved culm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geospiza Acutirostris
The Genovesa ground finch (''Geospiza acutirostris'') is a small bird native to the Galápagos Islands. It was considered a subspecies of the sharp-beaked ground finch (''Geospiza difficilis'') endemic to Genovesa Island.Grant, Peter R.; Grant, B. Rosemary & Petren, Kenneth (2000). The allopatric phase of speciation: the sharp-beaked ground finch (''Geospiza difficilis'') on the Galápagos islands. '' Biol. J. Linn. Soc.'' 69(3): 287–317. Rothschild, W. and E. Hartert. (1899). A Review of the Ornithology of the Galapagos Islands. With Notes on the Webster-Harris Expedition. ''Novitates Zoologicae'' Vol. VI, No. 2, pp. 85-205, 2 plates. The International Ornithologists' Union has split the species. Other taxonomic authorities still consider it conspecific. In the whole-genome phylogeny of Lamichhaney et al. (2017), ''G. acutirostris'' is shown to be very far from ''G. difficilis''. In fact, ''G. difficilis'' does not fall in the same part of the tree as other ''Geospiza''. Refer ...

Big Bird (finch)
Big Bird, also known as the Big Bird lineage, is one of the species of Darwin's finches that is exclusively present on Daphne Major of the Galápagos Islands. It originated from a single male Española cactus finch (''Geospiza conirostris'') that immigrated to Daphne Major in 1981, which founded a hybrid lineage by breeding with a female medium ground finch and creating 5 offspring. It resembles the medium ground finch but is relatively larger, hence, the name. The offspring tend to breed only with their own family members, thereby giving rise to reproductive isolation and undergoing speciation. Discovered by the research team of Peter and Rosemary Grant, the formation of Big Birds as a distinct species is considered as an instance of observed speciation and as a process of evolution by natural selection Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
