Creeping Vole
The creeping vole (''Microtus oregoni''), sometimes known as the Oregon meadow mouse, is a small rodent in the family Cricetidae. Ranging across the Pacific Northwest of North America, it is found in forests, grasslands, woodlands, and chaparral environments. The small-tailed, furry, brownish-gray mammal was first described in the scientific literature in 1839, from a specimen collected near the mouth of the Columbia River. The smallest vole in its range, it weighs around . At birth, they weigh , are naked, pink, unable to open their eyes, and the ear flaps completely cover the ear openings. Although not always common throughout their range, there are no major concerns for their survival as a species. Taxonomy The animal was described in 1839 by John Bachman. The original scientific name was ''Arvicola oregoni'' with a common name of the Oregon meadow mouse. The type specimen was an older male collected November 2, 1836 near the mouth of the Columbia River in Oregon. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Bachman
John Bachman (February 4, 1790 – February 24, 1874) was an American Lutheran minister, social activist and naturalist who collaborated with John James Audubon to produce ''Viviparous Quadrupeds of North America'' and whose writings, particularly ''Unity of the Human Race'', were influential in the development of the theory of evolution. He was married to the painter Maria Martin. Several species of animals are named in his honor. Life Bachman served the same Charleston, South Carolina church as pastor for 56 years but still found time to conduct natural history studies that caught the attention of noted bird artist John James Audubon and eminent scientists in England, Europe, and beyond. He was a proponent of secular and religious education and helped found Newberry College and the Lutheran Theological Southern Seminary, as well as the South Carolina Lutheran Synod. He was elected an Associate Fellow of the American Academy of Arts and Sciences in 1845. Bachman was a socia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dactyly
In biology, dactyly is the arrangement of digits (fingers and toes) on the hands, feet, or sometimes wings of a tetrapod animal. It comes from the Greek word δακτυλος (''dáktylos'') = "finger". Sometimes the ending "-dactylia" is used. The derived adjectives end with "-dactyl" or "-dactylous". As a normal feature Pentadactyly Pentadactyly (from Greek "five") is the condition of having five digits on each limb. It is traditionally believed that all living tetrapods are descended from an ancestor with a pentadactyl limb, although many species have now lost or transformed some or all of their digits by the process of evolution. However, this viewpoint was challenged by Stephen Jay Gould in his 1991 essay "Eight (Or Fewer) Little Piggies", where he pointed out polydactyly in early tetrapods and described the specializations of digit reduction. Despite the individual variations listed below, the relationship is to the original five-digit model. In reptiles, the limb ...

Mendocino City, California
Mendocino (Spanish for "of Mendoza") is an unincorporated community and census-designated place (CDP) in Mendocino County, California, United States. Mendocino is located south of Fort Bragg at an elevation of . The population of the CDP was 932 at the 2020 census. The town's name comes from Cape Mendocino to the north, named by early Spanish navigators in honor of Antonio de Mendoza, Viceroy of New Spain. Despite its small size, the town's scenic location on a headland surrounded by the Pacific Ocean has made it extremely popular as an artists' colony and with vacationers. History Prior to 1850, a Pomo settlement named Buldam was located near Mendocino on the north bank of the Big River. In 1850, the ship '' Frolic'' was wrecked a few miles north of Mendocino, at Point Cabrillo, and the investigation of the wreck by agents of Henry Meiggs sparked the development of the timber industry in the area. Mendocino itself was founded in 1852 as a logging community for what be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern California
Northern California (colloquially known as NorCal) is a geographic and cultural region that generally comprises the northern portion of the U.S. state of California.

Oregon
Oregon () is a state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as the strait now bearing his name. Spanish ships – 250 in as many years – would typically not land before reaching Cape Mendoci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border.

Incisive Foramen
In the human mouth, the incisive foramen (also known as: "''anterior palatine foramen''", or "''nasopalatine foramen''") is the opening of the incisive canals on the hard palate immediately behind the incisor teeth. It gives passage to blood vessels and nerves. The incisive foramen is situated within the incisive fossa of the maxilla. The incisive foramen is used as an anatomical landmark for defining the severity of cleft lip and cleft palate. The incisive foramen exists in a variety of species. Structure The incisive foramen is a funnel-shaped opening of the in the bone of the oral hard palate representing the inferior termination of the incisive canal. An oral prominence - the incisive papilla - overlies the incisive fossa. The incisive foramen is situated immediately behind the incisor teeth, and in between the two premaxillae. Contents The incisive foramen allows for blood vessels and nerves to pass. These include: * the pterygopalatine nerves to the hard palate. ...

Zygomatic Arches
In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); the tendon of the temporal muscle passes medial to (i.e. through the middle of) the arch, to gain insertion into the coronoid process of the mandible (jawbone). The jugal point is the point at the anterior (towards face) end of the upper border of the zygomatic arch where the masseteric and maxillary edges meet at an angle, and where it meets the process of the zygomatic bone. The arch is typical of '' Synapsida'' (“fused arch”), a clade of amniotes that includes mammals and their extinct relatives, such as ''Moschops'' and '' Dimetrodon''. Structure The zygomatic process of the temporal arises by two roots: * an ''an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
