Ryukyu Wood Pigeon
The Ryukyu wood pigeon (''Columba jouyi''), otherwise known as the silver-banded or silver-crescented pigeon is an extinct species of bird in the Columba genus in the family Columbidae. This wood pigeon was endemic to the Laurel forest habitat. Generality It is an extinct species of pigeon that was endemic to islands in the Okinawa archipelago south-west of the Japanese mainland. In the Okinawa group, it has been recorded from Iheyajima, Izenajima, Okinawa proper and the nearby islet Yagachijima. In the Kerama Retto to the west of Okinawa, it was found on Zamamijima, whereas in the Daitō group, some 300 km to the SE of Okinawa, it occurred on both major islets, Kita Daitōjima and Minami Daitōjima. In earlier times, it was most likely also found on other islands near Okinawa, such as Iejima. The species' scientific name honors Stejneger's friend, the specimen collector Pierre Louis Jouy. Extinction Like all species of Japanese wood pigeons, the Ryukyu wood pi ...

Leonhard Hess Stejneger
Leonhard Hess Stejneger (30 October 1851 – 28 February 1943) was a Norwegian-born American ornithologist, herpetologist and zoologist. Stejneger specialized in vertebrate natural history studies. He gained his greatest reputation with reptiles and amphibians. Wetmore, Alexander (1945). "Leonhard Hess Stejneger (1851-1943)". ''Biographical Memoir. Nat. Acad. Sci.'' 24: 145-195PDF/ref> Early life and family Stejneger was born in Bergen, Norway. His father was Peter Stamer Steineger, a merchant and auditor; his mother was Ingeborg Catharine (née Hess). Leonhard was the eldest of seven children. His sister Agnes Steineger was a Norwegian artist. Until 1880, the Steineger family had been one of the wealthy families in Bergen; at that time business reverses led to the father declaring bankruptcy. Stejneger attended the Smith Theological School in Bergen from 1859 to 1860, and Bergen Latin School until 1869. His interests in zoology developed early. By age sixteen he had a pr ...

Kerama Retto
The are a subtropical island group southwest of Okinawa Island in Japan. Geography Four islands are inhabited: Tokashiki Island, Zamami Island, Aka Island, and Geruma Island. The islands are administered as Tokashiki Village and Zamami Village within Shimajiri District. The Kerama-shotō coral reef is a Ramsar Site. The archipelago consists of the following islands (-jima/-shima) - inhabited ones are highlighted in blue - and rocks (other suffixes, unnamed entries) with an area of at least 0.01 km². Flora The archipelago has several extensive coral reefs. Two of them were designated as Ramsar sites in November 2005: a 120-hectare area along the west coast of Tokashiki-jima and around Hanari-jima, and a 233-hectare area around Ijakaja-jima, Gahi-jima and Agenashiku-jima , i.e. H. between Aka Island and Zamami Island. These reefs are home to 248 different coral species, most notably of the Acropora genus. On March 5, 2014, the waters and the islands were placed under pr ...

Extinct Animals Of Japan
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ...

Bird Extinctions Since 1500
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

American Naturalist
''The American Naturalist'' is the monthly peer-reviewed scientific journal of the American Society of Naturalists, whose purpose is "to advance and to diffuse knowledge of organic evolution and other broad biological principles so as to enhance the conceptual unification of the biological sciences." It was established in 1867 and is published by the University of Chicago Press. The journal covers research in ecology, evolutionary biology, population, and integrative biology. , the editor-in-chief is Daniel I. Bolnick. According to the ''Journal Citation Reports'', the journal had a 2020 impact factor of 3.926. History The journal was founded by Alpheus Hyatt, Edward S. Morse, Alpheus S. Packard Jr., and Frederick W. Putnam at the Essex Institute in Salem, Massachusetts. The first issue appeared in print dated March 1867."American Naturalist," in International Magazine Co., ''Periodicals,'' vol. 1, no. 1 (October-December 1917), pg. 5. In 1878 the journal was for sale and Ed ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...
