North American Jaguar
The North American jaguar is a jaguar (''Panthera onca'') population in North America, ranging from the southwestern United States to Central America. This population has declined over decades and was almost eliminated by 1960. Results of morphologic and genetic research failed to find evidence for subspecific differentiation. This population is also referred to as the "American jaguar" and "Central American jaguar". Taxonomic history Initially, a number of jaguar subspecies were described: * The taxonomic name ''Panthera onca goldmani'' (Mearns, 1901) was proposed as ranging from the Yucatán Peninsula in Mexico, in the north, to Belize and Honduras in the south. * ''Panthera onca hernandesii'' (Mearns, 1901) was proposed as native to Mexico and the United States of America. * ''Panthera onca veraecruscis'' (Nelson and Goldman, 1933) was proposed as ranging from Tabasco in Mexico to Texas in the United States. * ''Panthera onca arizonensis'' (Goldman, 1932) was proposed ...

El Jefe (jaguar)
El Jefe is an adult, male North American jaguar that was seen in Arizona. He was first recorded in the Whetstone Mountains in November 2011, and was later photographed over several years in the Santa Rita Mountains. From November 2011 to late 2015, El Jefe was the only wild jaguar verified to live in the United States since the death of Arizona Jaguar Macho B in 2009. According to "Notes on the Occurrences of Jaguars in Arizona and New Mexico", an article regarding jaguars in the Southwest US, "Sixty two jaguars have been reportedly killed or captured in the American Southwest since 1900." He was not seen in Arizona after September 2015 and it was presumed that he returned to Mexico, where the nearest breeding population of jaguars is located. This was confirmed almost seven years later in August 2022, when a collective of conservation groups announced that he had been photographed using a motion-detecting camera, on November 27, 2021, in the central part of the state of Sonora. ...

Maryland
Maryland ( ) is a state in the Mid-Atlantic region of the United States. It shares borders with Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware and the Atlantic Ocean to its east. Baltimore is the largest city in the state, and the capital is Annapolis. Among its occasional nicknames are '' Old Line State'', the ''Free State'', and the '' Chesapeake Bay State''. It is named after Henrietta Maria, the French-born queen of England, Scotland, and Ireland, who was known then in England as Mary. Before its coastline was explored by Europeans in the 16th century, Maryland was inhabited by several groups of Native Americans – mostly by Algonquian peoples and, to a lesser degree, Iroquoian and Siouan. As one of the original Thirteen Colonies of England, Maryland was founded by George Calvert, 1st Baron Baltimore, a Catholic convert"George Calvert and Cecilius Calvert, Barons Baltimore" William Hand Browne, ...

Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nebraska
Nebraska () is a state in the Midwestern region of the United States. It is bordered by South Dakota to the north; Iowa to the east and Missouri to the southeast, both across the Missouri River; Kansas to the south; Colorado to the southwest; and Wyoming to the west. It is the only triply landlocked U.S. state. Indigenous peoples, including Omaha, Missouria, Ponca, Pawnee, Otoe, and various branches of the Lakota ( Sioux) tribes, lived in the region for thousands of years before European exploration. The state is crossed by many historic trails, including that of the Lewis and Clark Expedition. Nebraska's area is just over with a population of over 1.9 million. Its capital is Lincoln, and its largest city is Omaha, which is on the Missouri River. Nebraska was admitted into the United States in 1867, two years after the end of the American Civil War. The Nebraska Legislature is unlike any other American legislature in that it is unicameral, and its members a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panthera Onca Augusta
''Panthera onca augusta'', commonly known as the Pleistocene jaguar or simply the giant jaguar, is an extinct subspecies of the jaguar that was endemic to North America during the Pleistocene epoch (1.8 mya–11,000 years ago). History and distribution Although '' P. onca'' still resides in the southern United States and several Native American tales possibly about ''P. onca augusta'' exist, the first published remains were described in 1872. The fossils were found by Ferdinand Vandeveer Hayden on the Platte River of Nebraska and sent to Joseph Leidy at the Academy of Natural Sciences in Philadelphia, who named them ''Felis augustus'' in 1872. The fossils consisted of a premolar IV and maxilla fragment, the type (USNM 1004), as well as another tooth and a distal humerus, though the humerus is likely that of ''Panthera atrox'' or ''Smilodon fatalis''. Leidy also mistakenly believed the fossils were from the Pliocene, but they actually come from the Pleistocene. Later in 1919, O ...

Early Pleistocene
The Early Pleistocene is an unofficial sub-epoch in the international geologic timescale in chronostratigraphy, being the earliest division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between 2.580 ± 0.005 Ma (million years ago) and 0.773 ± 0.005 Ma. The term Early Pleistocene applies to both the Gelasian Age (to 1.800 ± 0.005 Ma) and the Calabrian Age. While the Gelasian and the Calabrian have officially been defined by the International Union of Geological Sciences (IUGS) to effectively constitute the Early Pleistocene, the succeeding Chibanian and Tarantian ages have yet to be ratified. These proposed ages are unofficially termed the Middle Pleistocene and Late Pleistocene respectively. The Chibanian provisionally spans time from 773 ka to 126 ka, and the Tarantian from then until the definitive end of the whole Pleistocene, c. 9700 BC in the 10th millennium BC The 10th millennium BC spanned the ye ...

Beringia
Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72 degrees north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula. It includes the Chukchi Sea, the Bering Sea, the Bering Strait, the Chukchi and Kamchatka Peninsulas in Russia as well as Alaska in the United States and the Yukon in Canada. The area includes land lying on the North American Plate and Siberian land east of the Chersky Range. At certain times in prehistory, it formed a land bridge that was up to wide at its greatest extent and which covered an area as large as British Columbia and Alberta together, totaling approximately . Today, the only land that is visible from the central part of the Bering land bridge are the Diomede Islands, the Pribilof Islands of St. Paul and St. George, St. Lawrence Island, St. Matthew Island, and King Island. The term ''Berin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Panthera
''Panthera'' is a genus within the family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger (''P. tigris''), lion (''P. leo''), jaguar (''P. onca''), and leopard (''P. pardus'') on the basis of common cranial features. Results of genetic analysis indicate that the snow leopard (formerly ''Uncia uncia'') also belongs to the genus ''Panthera'' (''P. uncia''), a classification that was accepted by IUCN Red List assessors in 2008. The tiger, lion, jaguar and leopard are the only cat species with anatomical structures that enable them to roar; the snow leopard cannot. The primary reason for this was formerly assumed to be the incomplete ossification of the hyoid bone. However, new studies show the ability to roar is due to other morphological features, especially of the larynx. Etymology The word ''panther'' derives from clas ...

Reginald Innes Pocock
Reginald Innes Pocock Fellow of the Royal Society, F.R.S. (4 March 1863 – 9 August 1947) was a British zoologist. Pocock was born in Clifton, Bristol, the fourth son of Rev. Nicholas Pocock (historian), Nicholas Pocock and Edith Prichard. He began showing interest in natural history at St Edward's School, Oxford, St. Edward's School, Oxford. He received tutoring in zoology from Sir Edward Poulton, and was allowed to explore comparative anatomy at the Oxford University Museum of Natural History, Oxford Museum. He studied biology and geology at University College, Bristol, under Conwy Lloyd Morgan and William Johnson Sollas. In 1885, he became an assistant at the Natural History Museum, London, Natural History Museum, and worked in the section of entomology for a year. He was put in charge of the collections of Arachnida and Myriapoda. He was also given the task to arrange the British birds collections, in the course of which he developed a lasting interest in ornithology. The 2 ...
