Paeromopus Eldoradus
''Paeromopus'' is a genus of large cylindrical millipedes endemic to the U.S. state of California. All species exceed 10 centimeters (4 inches) in length, and the largest, '' P. paniculus, ''reaching 16.5 cm (6.5 inches) is the longest millipede species in North America. The genus was named by German entomologist Ferdinand Karsch in 1881 and contains four species: three occupying small ranges in the Sierra Nevada mountains and one occupying a large range including the Sierra Nevada and much of Northern California to the Central Coast. Description ''Paeromopus ''millipedes are long and cylindrical, measuring in length and up to 8 mm (0.3 in) wide, with 68 to 80 body segments. The body color in most is brown to black with bands of light brown or yellow, although some individuals are dark gray or bluish gray with indistinct bands. The legs are relatively long, and the first pair of legs in males is extremely reduced in size. Like other paeromopodids, species of '' ...

Sierra Nevada (U
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 ...

Central Valley (California)
The Central Valley is a broad, elongated, flat valley that dominates the interior of California. It is wide and runs approximately from north-northwest to south-southeast, inland from and parallel to the Pacific coast of the state. It covers approximately , about 11% of California's land area. The valley is bounded by the Coast Ranges to the west and the Sierra Nevada to the east. The Central Valley is a region known for its agricultural productivity: it provides more than half of the fruits, vegetables, and nuts grown in the United States. More than of the valley are irrigated via reservoirs and canals. The valley hosts many cities, including the state capital Sacramento; as well as Redding, Chico, Stockton, Modesto, Merced, Fresno, Visalia, and Bakersfield. The Central Valley watershed comprises , or over a third of California. It consists of three main drainage systems: the Sacramento Valley in the north, which receives over of rain annually; the drier San J ...

Author Citation (zoology)
In zoological nomenclature, author citation refers to listing the person (or team) who first makes a scientific name of a taxon available. This is done in a scientific work while fulfilling the formal requirements under the International Code of Zoological Nomenclature ("the Code"). According to Article 51.1 of the Code, "the name of the author does not form part of the name of a taxon and its citation is optional, although customary and often advisable", however recommendation 51A suggests: "The original author and date of a name should be cited at least once in each work dealing with the taxon denoted by that name. This is especially important and has a unique character between homonyms and in identifying species-group names which are not in their native combinations". For the seek of information retrieval, the author citation and year appended to the scientific name, e.g. genus-species-author-year, genus-author-year, family-author-year, etc., is often considered a "de facto" un ...

Cascade Range
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at . part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and ...

Coast Ranges (California)
The Coast Ranges of California span from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains. Physiographically, they are a section of the larger Pacific Border province, which in turn is part of the larger Pacific Mountain System physiographic division. UNESCO has included the "California Coast Ranges Biosphere Reserve" in its Man and the Biosphere Programme of World Network of Biosphere Reserves since 1983. * Physiography The northern end of the California Coast Ranges overlap the southern end of the Klamath Mountains for approximately 80 miles on the west. They extend southward for more than 600 miles to where the coastline turns eastward along the Santa Barbara Channel, around the area of Point Conception. Here the southern end meets the Los Angeles Transverse Ranges, or ''Sierras de los Angeles''. The rocks themselves that compr ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simple Eye In Invertebrates
A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-lensed "compound eye", and is not necessarily at all simple in the usual sense of the word. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods. They possess a wide variety of novel solutions to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of humans and of other large animals such as most cephalopods, are '' camera eyes'' and ...

Paeromopodid
Paeromopodidae is a family of large cylindrical millipedes of the order Julida native to the western United States of America. The family contains two genera and ten species and includes the longest millipedes in North America, with individuals reaching up to long. Description Paeromopodids possess 60 to 80 body segments and range from long and 2 to 8 mm wide as adults. Paeromopodids have distinct parallel grooves called ''striae'' on their body rings that give a somewhat roughened texture and distinguishes them from other cylindrical western millipedes. Individuals may be rather uniformly blue gray, or colored in alternating bands of light and dark brown, or may possess a dorsal lengthwise stripe of yellow or light brown. Distribution Paeromopodids are endemic to the United States and occur in two distinct areas: the first is a large Pacific coast range extending from Washington state to the southern Sierra Nevada and Death Valley region of California and east to the War ...

Arthropod Leg
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
