Chestnut-bellied Monarch
The chestnut-bellied monarch (''Monarcha castaneiventris'') or chestnut-bellied monarch-flycatcher is a species of bird in the family Monarchidae. It is endemic to the Solomon Islands. Subspecies Four subspecies are recognized: * ''M. c. castaneiventris'' - Verreaux, 1858: Found on Choiseul, Santa Isabel, Guadalcanal and Malaita * ''M. c. obscurior'' - Mayr, 1935: Found on Russell Islands * Makira monarch (''M. c. megarhynchus'') - Rothschild & Hartert, 1908: Found on Makira * Makira monarch (''M. c. ugiensis'') - ( Ramsay, EP, 1882): Originally described as a separate species in the genus ''Pomarea''. Found on Ugi Island Behaviour and ecology In 2009, it was reported that a genetic change in some members of this species caused their colouration and songs to be different from other members of the species. As a result, members in one group did not recognize members in the other, so the two groups became reproductively isolated from each other. It was thought that over time, ...

John Gerrard Keulemans
Johannes Gerardus Keulemans (J. G. Keulemans) (8 June 1842 – 29 March 1912) was a Dutch bird illustrator. For most of his life he lived and worked in England, illustrating many of the best-known ornithology books of the nineteenth century. Biography Keulemans was born in Rotterdam. As a young man he collected animal specimens for museums such as the Natural History Museum in Leiden, whose director, Hermann Schlegel, encouraged Keulemans and sent him on the 1864 expedition to West Africa. In 1869, he was persuaded by Richard Bowdler Sharpe to illustrate his '' Monograph of the Alcedinidae, or Family of Kingfishers'' (1868-1871) and to move to England, where he lived for the rest of his life. He was married twice, and had eight children by his first wife and seven children by his second wife. Only nine of his children reached adulthood. He also wrote topics on spirituality, and claimed he had a premonition at the moment of death of one of his sons. He died in Ilford, Essex (now ...

Endemic Birds Of The Solomon Islands
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monarcha
''Monarcha'' is a genus of bird in the family Monarchidae. They are found in Australia and Melanesia. Taxonomy and systematics The genus ''Monarcha'' was introduced by naturalists Nicholas Vigors and Thomas Horsfield in 1827 with the black-faced monarch (''Monarcha melanopsis'') as the type species. The genus formerly included many more species. Based on the results of a molecular phylogenetic study published in 2005 nineteen species were moved to the resurrected genus '' Symposiachrus'' and three to ''Carterornis''. Extant species The genus ''Monarcha'' contains the following nine species: * Island monarch (''Monarcha cinerascens'') * Black-faced monarch (''Monarcha melanopsis'') * Black-winged monarch (''Monarcha frater'') * Bougainville monarch (''Monarcha erythrostictus'') * Chestnut-bellied monarch (''Monarcha castaneiventris'') * White-capped monarch (''Monarcha richardsii'') * Yap monarch (''Monarcha godeffroyi'') * Tinian monarch (''Monarcha takatsukasae'') ...

Biological Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speciation
Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book ''On the Origin of Species''. He also identified sexual selection as a likely mechanism, but found it problematic. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric speciation, allopatric, peripatric speciation, peripatric, parapatric speciation, parapatric, and sympatric speciation, sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments of speciation, laboratory experiments. Whether genetic drift is a minor or major contributor to speciation is the subject of much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Makira
The island of Makira (also known as San Cristobal and San Cristóbal) is the largest island of Makira-Ulawa Province in the Solomon Islands. It is third most populous island after Malaita and Guadalcanal, with a population of 55,126 as of 2020. The island is located east of Guadalcanal and south of Malaita. The largest and capital city is Kirakira. History The first recorded sighting by Europeans of Makira was by the Spanish expedition of Álvaro de Mendaña in June 1568. More precisely the sighting and also landing in San Cristobal was due to a local voyage that set out from Guadalcanal in a small boat, in the accounts the brigantine ''Santiago'', commanded by Alférez Hernando Enriquez and having Hernán Gallego as pilot. They charted it as ''San Cristóbal''.Brand, Donald D. ''The Pacific Basin: A History of its Geographical Explorations'' The American Geographical Society, New York, 1967, p.133.

Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russell Islands
:''See also Russell Island (other).'' The Russell Islands are two small islands (Pavuvu and Mbanika), as well as several islets, of volcanic origin, in the Central Province of Solomon Islands. They are located approximately northwest of Guadalcanal. The islands are partially covered in coconut plantations, and have a copra and oil factory at Yandina (on Mbanika). Yandina also has basic services, including a store, post office, and airport. People The Lavukal people live on these islands. Their language is Lavukaleve. There is also a settlement of Polynesians, resettled from Tikopia, that lives in Nukufero on the west side of the larger island, Pavuvu. In 1956 the Levers Pacific Plantations company donated 80 acres for use for this resettlement, and later added another 125 acres in the 1960s. This land was subdivided into 4 acre lots for each family. Five hundred people from Tikopia had migrated there by 1965. Te Ariki Taumako who was the third Chief of Tikopia, made a ...
