Grylloblattidae
Grylloblattidae, commonly known as the icebugs, or ice crawlers, is a family of extremophile (psychrophile) and wingless insects that live in the cold on top of mountains and the edges of glaciers. They belong, along with Mantophasmatidae (rock crawlers), to the order Notoptera. Grylloblattids are wingless insects mostly less than 3 cm long, with a head resembling that of a cockroach, with long antennae and having elongated cerci arising from the tip of their abdomen. They cannot tolerate warmth (most species will die at 10 °C) and many species have small distribution ranges. Overview Grylloblattids, ice crawlers or icebugs puzzled the scientists who discovered them in 1914, E.M. Walker and T.B. Kurata; the first species named was '' Grylloblatta campodeiformis'', which means "cricket-cockroach shaped like a '' Campodea''" (a kind of two-pronged bristletail). Most are nocturnal and appear to feed on detritus. They have long antennae (23–45 segments) and long cerci (5†... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Echo Summit
Echo Summit is a mountain pass over the Sierra Nevada in the western United States, located in eastern El Dorado County, California. At above sea level, it is the highest point on U.S. Route 50 in California, which traverses it at postmile 66.48 between Twin Bridges and Meyers, south of Lake Tahoe. The "Sierra Nevada Southern Route" (aka the "Pioneer Route") of the Lincoln Highway, the first road across the United States, was routed over nearby Johnson Pass in 1913. The current alignment over Echo Summit was constructed between 1936 and 1939. The "Sierra Nevada Northern Route" of the Lincoln Highway went over Donner Pass. Echo Summit is a trailhead for the Pacific Crest National Scenic Trail.1968 Olympians Return to Echo Summit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Nevada
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils Po ...

Placer County
Placer County ( ; Spanish for "sand deposit"), officially the County of Placer, is a county in the U.S. state of California. As of the 2020 census, the population was 404,739. The county seat is Auburn. Placer County is included in the Greater Sacramento metropolitan area. It is in both the Sacramento Valley and Sierra Nevada regions, in what is known as the Gold Country. The county stretches roughly 65 miles (105 km) from Sacramento's suburbs at Roseville to the Nevada border and the shore of Lake Tahoe. Etymology The discovery of gold in 1848 brought tens of thousands of miners from around the world during the California Gold Rush. In addition, many more thousands came to provide goods and services to the miners. On April 25, 1851, the fast-growing county was formed from parts of Sutter and Yuba Counties with Auburn as the county seat. Placer County took its name from the Spanish word for sand or gravel deposits containing gold. Miners washed away the gravel, leaving ...

Nevada County, California
Nevada County () is a county located in the U.S. state of California, in the Sierra Nevada. As of the 2020 census, the population was 102,241. The county seat is Nevada City. Nevada County comprises the Truckee-Grass Valley, CA Micropolitan Statistical Area, which is also included in the Sacramento- Roseville, CA Combined Statistical Area, part of the Mother Lode Country. History Created in 1851, from portions of Yuba County, Nevada County was named after the mining town of Nevada City, a name derived from the Sierra Nevada Mountains. The word ''nevada'' is Spanish for "snowy" or "snow-covered." Charles Marsh was one of the first settlers in what became Nevada City and perhaps the one who named the town. He went on to build extensive water flumes/ditches/canals in the area, and was influential in the building of the first transcontinental railroad as well as the Nevada County Narrow Gauge Railroad. Nevada City was the first to use the word "Nevada" in its name. In 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Of The United States
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
