Aprosphylosomatidae
''Aprosphylosoma darceneae'' is a species of cylindrical julidan millipede found only in the U.S. state of Oregon and comprising the sole species of the family Aprosphylosomatidae. It is known from only a single known specimen collected from Oregon Caves National Monument in 1956 that measures approximately long and 1 mm wide, possessing 59 body segments. The first pair of legs are extremely reduced into non-jointed, peg-like structures. The body color is yellowish brown with darker brown mottling on the dorsal surface, and the legs are white. ''Aprosphylosoma'' was originally classified as a new distinct subfamily ("Aprosphylosomatinae") of the family Nemasomatidae. Subsequent cladistic analysis placed ''Aprosphylosoma'' into the family Paeromopodidae 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 Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julida
Julida is an order of millipedes. Members are mostly small and cylindrical, typically ranging from in length. Eyes may be present or absent, and in mature males of many species, the first pair of legs is modified into hook-like structures. Additionally, both pairs of legs on the 7th body segment of males are modified into gonopods. Distribution Julida contains predominantly temperate species ranging from North America to Panama, Europe, Asia north of the Himalayas, Asir region, Saudi Arabia, and Southeast Asia. Classification The order Julida contains approximately 750 species, divided into the following superfamilies and families: ;Blaniuloidea C. L. Koch, 1847 *Blaniulidae C. L.

Endemic Fauna Of Oregon
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 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millipedes Of North America
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from the Latin for "thousand feet", no species was known to have 1,000 or more until the discovery of ''Eumillipes persephone'', which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eating decaying leaves and other dead plant matter. Some eat fungi or d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paeromopodidae
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 Warn ...

Cladistic
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Oregon Caves National Monument
Oregon Caves National Monument and Preserve is a protected area in the northern Siskiyou Mountains of southwestern Oregon in the United States. The 4,554-acre (1,843 ha) park, including the marble cave, is 20 miles (32 km) east of Cave Junction, on Oregon Route 46. The protected area, managed by the National Park Service (NPS), is in southwestern Josephine County, near the Oregon–California border. Elijah Davidson, a resident of nearby Williams, discovered the cave in 1874. Over the next two decades, private investors failed in efforts to run successful tourist ventures at the publicly owned site. After passage of the Antiquities Act by the United States Congress, in 1909 President William Howard Taft established Oregon Caves National Monument, to be managed by the United States Forest Service (USFS). The growing popularity of the automobile, construction of paved highways, and promotion of tourism by boosters from Grants Pass led to large increases in cave visi ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system.
