Petroica Multicolor
The Norfolk robin (''Petroica multicolor''), also known as the Norfolk Island scarlet robin or Norfolk Island robin, is a small bird in the Australasian robin family Petroicidae. It is endemic to Norfolk Island, an Australian territory in the Tasman Sea, between Australia and New Zealand. Taxonomy The Norfolk robin was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the flycatchers in the genus '' Muscicapa'' and coined the binomial name ''Muscicapa multicolor''. Gmelin based his description on the "red-bellied flycatcher" from Norfolk Island that had been described and illustrated in 1783 by the English ornithologist John Latham in his book ''A General Synopsis of Birds''. Latham had examined a specimen of a male bird owned by the naturalist Joseph Banks and a female bird in the Leverian Museum in London. The Norfolk robin is now placed with 13 other spec ...

Norfolk Island
Norfolk Island ( , ; ) is an States and territories of Australia, external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia, directly east of Australia's Evans Head, New South Wales, Evans Head and about from Lord Howe Island. Together with the neighbouring Phillip Island (Norfolk Island), Phillip Island and Nepean Island (Norfolk Island), Nepean Island, the three islands collectively form the Territory of Norfolk Island. At the 2021 Australian census, 2021 census, it had 2,188 inhabitants living on a total area of about . Its capital is Kingston, Norfolk Island, Kingston. East Polynesians were the first to settle Norfolk Island, but they had already departed when Kingdom of Great Britain, Great Britain settled it as part of its 1788 colonisation of Australia. The island served as a penal colony, convict penal settlement from 6 March 1788 until 5 May 1855, except for an 11-year hiatus between 15 February 1814 and 6 June 1825, when ...

Leverian Collection
The Leverian collection was a natural history and ethnographic collection assembled by Ashton Lever. It was noted for the content it acquired from the voyages of Captain James Cook. For three decades it was displayed in London, being broken up by auction in 1806. The first public location of the collection was the Holophusikon, also known as the Leverian Museum, at Leicester House, Westminster, Leicester House, on Leicester Square, from 1775 to 1786. After it passed from Lever's ownership, it was displayed for nearly twenty years more at the purpose-built Blackfriars Rotunda#James Parkinson and the Leverian collection, Blackfriars Rotunda just across the Thames, sometimes called Parkinson's Museum for its subsequent owner, James Parkinson (c. 1730–1813). At Alkrington Lever collected fossils, shells, and animals (birds, insects, reptiles, fish, monkeys) for many years, accumulating a large collection at his home at Alkrington, near Manchester. Admittance to the collection was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral Cat
A feral cat or a stray cat is an unowned domestic cat (''Felis catus'') that lives outdoors and avoids human contact; it does not allow itself to be handled or touched, and usually remains hidden from humans. Feral cats may breed over dozens of generations and become a local apex predator in urban, savannah and bushland environments, and especially on islands where native animals did not evolve alongside predators. Some feral cats may become more comfortable with people who regularly feed them, but even with long-term attempts at socialization of animals, socialization, they usually remain aloof and reject human touch. Of the 700 million cats in the world, an estimated 480 million are feral. Feral cats are devastating to wildlife, and conservation biologists consider them to be one of the worst invasive species on Earth. They are included in the list of 100 of the World's Worst Invasive Alien Species, the world's 100 worst invasive alien species. Attempts to control feral cat ...

Black Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious Pest (organism), pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually Morph (zoology), color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A ty ...

Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...

Rainforest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere. Definition Rainforests are cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical
The subtropical zones or subtropics are geographical zone, geographical and Köppen climate classification, climate zones immediately to the Northern Hemisphere, north and Southern Hemisphere, south of the tropics. Geographically part of the Geographical zone#Temperate zones, temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° to 40° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical climate, humid subtropical (Köppen climate classification: Cfa/Cwa), where rainfall is often concentrated in the warmest months, for example list of regions of China, Southeast China and the Southeastern United States, and Mediterranean climate, dry summer or Mediterranean climate (Köppen climate classification: Csa/Csb), where seasonal rainfall is concentrated in the cooler ...

Pacific Robin
The Pacific robin (''Petroica pusilla''), is a red-breasted Australasian robin in the passerine bird genus ''Petroica'' found in Melanesia and Polynesia. It is similar in plumage to the scarlet robin of Australia, and until recently the two were considered conspecific until split in 1999 by Schodde and Mason. Thirteen subspecies of Pacific robin are currently recognised, and these subspecies display considerable variation in plumage, foraging preferences, and habitat. The Norfolk robin was previously considered a subspecies of the Pacific robin, but is now considered a distinct species.Kearns, A. M. et al. (2016) Norfolk Island Robins are a distinct endangered species: ancient DNA unlocks surprising relationships and phenotypic discordance within the Australo-Pacific Robins.

Scarlet Robin
The scarlet robin (''Petroica boodang'') is a common red-breasted Australasian robin in the passerine bird genus ''Petroica''. The species is found on continental Australia and its offshore islands, including Tasmania. The species was originally split in 1999 by Schodde and Mason, and as the original collection by Gmelin was from Norfolk Island, this retained the name of ''multicolor'', and is now known as the Norfolk robin. Taxonomy There are three recognised subspecies of ''Petroica boodang'': the nominate subspecies ''P.b.boodang'' is found in mainland southeastern Australia; ''P.b.leggii'' is found in Tasmania and Flinders Island in the Bass Strait; and ''P.b.campbelli'' occurs in southwestern Western Australia. Description Like the rest of the Australasian robins, the scarlet robins are stocky passerines with large heads. They range in size from 12 to 13.5 cm in length and weigh between 12 and 14 g. The plumage is sexually dimorphic. The males have black hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...
