Peromyscus Nesodytes
The giant island deer mouse (''Peromyscus nesodytes'') became extinct approximately 8,000 years BP and lived during the late Pleistocene on California’s Channel Islands.Guthrie, D.A. (1993). New information on the prehistoric fauna of San Miguel Island: in F.G. Hochberg, ed., Third Channel Islands symposium, Santa Barbara, CA, Santa Barbara Museum of Natural History, p. 405-416. Overview In 1934, Robert W. Wilson designated ''P. nesodytes'' as a new species after discovering a mouse bone (a right ramus of the mandible). He writes, “The outstanding character of ''P. nesodytes'' is its large size, which is greater than any living species of ''Peromyscus'' native to the United States.” The only larger mice known are the extant mice of the genus '' Megadontomys'' found in Mexico and Central America. The mouse “generally considered ancestral to ''P. nesodytes''” is ''Peromyscus anyapahensis''.''P. anyapahensis'' is also extinct; it is smaller in body size than ''P. nesody ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Barn Owl
The barn owl (''Tyto alba'') is the most widely distributed species of owl in the world and one of the most widespread of all species of birds, being found almost everywhere except for the polar and desert regions, Asia north of the Himalayas, most of Indonesia, and some Pacific Islands. It is also known as the common barn owl, to distinguish it from the other species in its family, Tytonidae, which forms one of the two main lineages of living owls, the other being the typical owls (''Strigidae''). There are at least three major lineages of barn owl: the western barn owl of Europe, western Asia, and Africa; the eastern barn owl of southeastern Asia and Australasia; and the American barn owl of the Americas. Some taxonomic authorities classify barn owls differently, recognising up to five separate species; and further research needs to be done to resolve the disparate taxonomies. There is considerable variation of size and colour among the approximately 28 subspecies, but most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of California
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene Extinctions
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Fauna Of The Channel Islands Of California
The wildlife of the Channel Islands of California is wide and diverse, including many endemic species. While the land wildlife is slightly limited, there being only one large, naturally predatory, and native mammal, the small island fox, marine life can include anything from kelp forests to great white sharks. Flora Flora on the Channel Islands include endemic subspecies of pine, oak, and the island tree mallow. Santa Rosa Island holds two groves of the Torrey pine subspecies ''Pinus torreyana'' var. ''insularis'', which is endemic to the island. Torrey pines are the United States' rarest pine species. The islands also house many rare and endangered plants, including the island barberry, the island rushrose, and the Santa Cruz Island lace pod. Giant kelp forests surround the islands and act as a source of nutrition and protection for other animals. Invasive species, such as the Australian blue gum tree, olive tree, sweet fennel and Harding grass threaten native species thro ...

Peromyscus Maniculatus
''Peromyscus maniculatus'' is a rodent native to eastern North America. It is most commonly called the eastern deer mouse; when formerly grouped with the western deer mouse (''P. sonoriensis''), it was referred to as the North American deermouse and is fairly widespread across most of North America east of the Mississippi River, with the major exception being the lowland southeastern United States. Like other ''Peromyscus'' species, it can be a vector and carrier of emerging infectious diseases such as hantaviruses and Lyme disease. It is closely related to ''Peromyscus leucopus'', the white-footed mouse. Overview The species in its former broad sense had 61 subspecies, but some of these now belong to ''P. sonoriensis''. They are all tiny mammals that are plentiful in number. The deer mouse is a small rodent that lives in eastern North America and is closely related to the white-footed mouse, ''Peromyscus leucopus''.The New Encyclopædia Britannica. 2007.

Peromyscus
''Peromyscus'' is a genus of rodents. They are commonly referred to as deer mice or deermice, not to be confused with the chevrotain or "mouse deer". They are New World mice only distantly related to the common house and laboratory mouse, ''Mus musculus''. From this relative, ''Peromyscus'' species are distinguished by relatively larger eyes, and also often two-tone coloring, with darker colors over the dorsum (back), and white abdominal and limb hair-coloring. In reference to the coloring, the word ''Peromyscus'' comes from Greek words meaning "booted mouse". They are also accomplished jumpers and runners by comparison to house mice, and their common name of "deer mouse" (coined in 1833) is in reference to this agility. The most common species of deer mice in the continental United States are two closely related species, '' P. maniculatus'' and '' P. leucopus''. In the United States, ''Peromyscus'' is the most populous mammalian genus overall, and has become notorious in the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chumash People
The Chumash are a Native American people of the central and southern coastal regions of California, in portions of what is now San Luis Obispo, Santa Barbara, Ventura and Los Angeles counties, extending from Morro Bay in the north to Malibu in the south. Their territory included three of the Channel Islands: Santa Cruz, Santa Rosa, and San Miguel; the smaller island of Anacapa was likely inhabited seasonally due to the lack of a consistent water source. Modern place names with Chumash origins include Malibu, Nipomo, Lompoc, Ojai, Pismo Beach, Point Mugu, Port Hueneme, Piru, Lake Castaic, Saticoy, Simi Valley and Somis. Archaeological research demonstrates that the Chumash people have deep roots in the Santa Barbara Channel area and lived along the southern California coast for millennia. History Prior to European contact (pre-1542) Indigenous peoples have lived along the California coast for at least 11,000 years. Sites of the Millingstone Horizon date from 7000 ...
