Scarlet Myzomela
The scarlet myzomela or scarlet honeyeater (''Myzomela sanguinolenta'') is a small passerine bird of the honeyeater family Meliphagidae native to Australia. It was first described by English ornithologist John Latham in 1801. At long, it is the smallest honeyeater in Australia. It has a short tail and relatively long down-curved bill. It is sexually dimorphic; the male is a striking bright red with black wings, while the female is entirely brown. The species is more vocal than most honeyeaters, and a variety of calls have been recorded, including a bell-like tinkling. The scarlet myzomela is found along most of the eastern coastline, from Cape York in the far north to Gippsland in Victoria. It is migratory in the southern parts of its range, with populations moving north in the winter. Its natural habitat is forest, where it forages mainly in the upper tree canopy. It is omnivorous, feeding on insects as well as nectar. Up to three broods may be raised over the course of a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Latham (ornithologist)
John Latham (27 June 1740 – 4 February 1837) was an English physician, naturalist and author. His main works were ''A General Synopsis of Birds'' (1781–1801) and ''General History of Birds'' (1821–1828). He was able to examine specimens of Australian birds which reached England in the last twenty years of the 18th century, and was responsible for providing English names for many of them. He named some of Australia's most famous birds, including the emu, sulphur-crested cockatoo, wedge-tailed eagle, superb lyrebird, Australian magpie, magpie-lark and pheasant coucal. He was also the first to describe the hyacinth macaw. Latham has been called the "grandfather" of Australian ornithology. Biography John Latham was born on 27 June 1740 at Eltham in northwest Kent. He was the eldest son of John Latham (died 1788), a surgeon, and his mother, who was a descendant of the Sothebys, in Yorkshire. He was educated at Merchant Taylors' School and then studied anatomy under William Hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Francis Stephens
James Francis Stephens (16 September 1792 – 22 December 1852) was an English entomologist and naturalist. He is known for his 12 volume ''Illustrations of British Entomology'' (1846) and the ''Manual of British Beetles'' (1839). Early life Stephens was born in Shoreham-by-Sea and studied at Christ's Hospital. His father was a navy captain William James Stephens (d. 1799) and his mother was Mary Peck (later Mrs Dallinger). He went to school at the Blue Coat School, Hertford and later at Christ's Hospital, London. He was then sent to study under Shute Barrington (1734–1826), the bishop of Durham in 1800. He left in 1807 and worked as a clerk in the Admiralty office, Somerset House, from 1807 to 1845 thanks to his uncle Admiral Stephens. Entomology Stephens took an interest in natural history even as a schoolboy. He wrote a manuscript ''Catalogue of British Animals'' in 1808. He was elected fellow of the Linnean Society on 17 February 1815, and of the Zoological Society o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardinal Myzomela
The cardinal myzomela (''Myzomela cardinalis'') is a species of bird in the honeyeater family Meliphagidae. It is named for the scarlet color of the male. It is found in American Samoa, New Caledonia, Samoa, Solomon Islands, and Vanuatu, as well as some islands in Micronesia such as Yap. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest. It frequents areas with flowers, such as gardens. This is a small, active bird, measuring about from bill to tail. Males are red and black in coloration, females are grayish-olive, sometimes with a red cap or red head. Its long, curved bill is especially adapted for reaching into flowers for nectar. Cardinal myzomela populations have vanished from the island of Guam since the invasion of the brown tree snake.

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and guanine; and pyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the ...

Biological Specificity
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 so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Caledonian Myzomela
The New Caledonian myzomela (''Myzomela caledonica'') is a species of bird in the honeyeater family Meliphagidae. The species is sometimes considered to be conspecific with (the same species as) the scarlet myzomela of Australia. It is endemic to New Caledonia, where it occurs on the island of Grande Terre and the Isle of Pines. In New Caledonia its natural habitat is humid rainforest, stunted hill forest and savanna woodland. It has also moved into modified habitat such as plantations and gardens. It is around 11 cm in length and typically weighs 6.5 to 8 grams. The males are slightly heavier than the females. The plumage Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes.
