Trichopetalum Whitei
''Trichopetalum whitei'', common name Luray Caverns blind cave millipede, is a rare troglobitic (obligate cavernicolous) millipede of the upper Potomac River drainage in four Virginia counties and three West Virginia counties. It has been recorded from 12 caves across this range, including the Luray Caverns where it was first discovered and described. Description ''T. whitei'' is an eyeless, white (unpigmented) millipede. In common with all trichopetalids, it has rows of very elongate segmental setae extending in rows along the dorsal side. Proper identification requires microscopic examination and dissection of the gonopods (copulatory apparatus) by a specialist skilled in millipede identification. Ecology and range ''T. whitei'' is a troglobite and occurs only in caves, especially occurring on damp, rotting wood. ''T. whitei'' is presumably omnivorous, although nothing is known of its feeding preferences. Feeding is presumed to consist of picking up or scraping material from ...

Troglobite
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves. These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors ( subtroglophiles and trogloxenes). Land-dwelling troglobites may be referred to as troglofauna, while aquatic species may be called stygofauna, although for these animals the term ''stygobite'' is preferable. Troglobites typically have evolutionary adaptations to cave life. Examples of such adaptations include slow metabolism, reduced energy consumption, better food usage efficiency, decrease or loss of eyesight (anophthalmia), and depigmentation (absence of pigment in the integument). Conversely, as opposed to lost or reduced functions, many species have evolved elongated antenna and locomotory appendages, in order to better move around and respond to environmental s ...

Spermatophore
A spermatophore or sperm ampulla is a capsule or mass containing spermatozoa created by males of various animal species, especially salamanders and arthropods, and transferred in entirety to the female's ovipore during reproduction. Spermatophores may additionally contain nourishment for the female, in which case it is called a nuptial gift, as in the instance of bush crickets. In the case of the toxic moth ''Utetheisa ornatrix'', the spermatophore includes sperm, nutrients, and pyrrolizidine alkaloids which prevent predation because it is poisonous to most organisms. However, in some species such as the Edith's checkerspot butterfly, the "gift" provides little nutrient value. The weight of the spermatophore transferred at mating has little effect on female reproductive output. Arthropods Spermatophores are the norm in arachnids and several soil arthropods. In various insects, such as bush crickets, the spermatophore is often surrounded by a proteinaceous spermatophylax. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod Coxa
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 artic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pocahontas County, West Virginia
Pocahontas County is a county located in the U.S. state of West Virginia. As of the 2020 census, the population was 7,869. Its county seat is Marlinton. The county was established in 1821.

Greenbrier County, West Virginia
Greenbrier County () is a county in the U.S. state of West Virginia. As of the 2020 census, the population was 32,977. Its county seat is Lewisburg. The county was formed in 1778 from Botetourt and Montgomery counties in Virginia. History Prior to the arrival of European-American settlers around 1740, Greenbrier County, like most of West Virginia, was used as a hunting ground by the Shawnee and Cherokee nations. They called this land ''Can-tuc-kee''. Shawnee leaders, including Pucksinwah and later his son Tecumseh, were alarmed by the arrival of the European settlers, who by 1771 had set up extensive trade in the area. The day books of early merchants Sampson and George Mathews recorded sales to the Shawnee that included such luxury items as silk, hats, silver, and tailor-made suits.Handley, Harry E. (1963), "The Mathews Trading Post", published in ''The Journal of the Greenbrier Historical Society'': Volume 1, Number 1 (Lewisburg, West Virginia: Greenbrier Historical Soc ...

Pendleton County, West Virginia
Pendleton County is a county located in the U.S. state of West Virginia. As of the 2020 census, the population was 6,143, making it the second-least populous county in West Virginia. Its county seat is Franklin. The county was created by the Virginia General Assembly in 1788 from parts of Augusta, Hardy, and Rockingham Counties and was named for Edmund Pendleton (1721–1803), a distinguished Virginia statesman and jurist. Pendleton County was strongly pro-Confederate during the American Civil War; however, there were pockets of Unionists who supported the state government in Wheeling. Spruce Knob, located in Pendleton County, is the highest point in the state and in the Alleghenies, its elevation being 4,863 feet. Parts of the Monongahela and George Washington National Forests are also located in Pendleton.

Grant County, West Virginia
Grant County is a county in the U.S. state of West Virginia. As of the 2020 census, the population was 10,976. Its county seat is Petersburg. The county was created from Hardy County in 1866 and named for Civil War General Ulysses S. Grant. History The territory that became Grant County in 1866 was originally part of Hampshire County, the oldest county formed within the present boundaries of West Virginia, in 1754. In 1786, Hardy County was formed from the southern portion of Hampshire County. The county's boundaries were relatively stable from 1788 until 1866, when Grant County was formed from the western portion of Hardy. The first counties formed in the state following the admission of West Virginia to the Union were Grant and Mineral in 1866, the latter formed from the western portion of Hampshire County, and thus adjoining Grant. They were the fifty-first and fifty-second counties in West Virginia, and only Lincoln Lincoln most commonly refers to: * Abraham Lincol ...

Hardy County, West Virginia
Hardy County is a county in the U.S. state of West Virginia. As of the 2020 census, the population was 14,299. Its county seat is Moorefield. The county was created from Hampshire County in 1786 and named for Samuel Hardy, a distinguished Virginian. History The first European known to visit this area was John Van Meter in 1725. The earliest permanent European settlements were established in the 1730s. Hardy County was formed in 1786 from Hampshire County in Virginia. It was one of fifty counties admitted to the Union as the state of West Virginia in 1863. That year, the newly independent state's counties were divided into civil townships, with the intention of encouraging local government. This proved impractical in the heavily rural state, and in 1872 the townships were converted into magisterial districts. Hardy County was divided into three districts: Capon, Lost River, and Moorefield. A fourth district, South Fork, was formed in 1873 from part of Moorefield Distr ...

Shenandoah County, Virginia
Shenandoah County (formerly Dunmore County) is a county located in the Commonwealth of Virginia. As of the 2020 United States Census, the population was 44,186. Its county seat is Woodstock. It is part of the Shenandoah Valley region of Virginia. History The Senedos, possibly an Iroquoian group, are thought to have occupied the area at one time, until they were said to have been slaughtered by the Catawba in the latter 17th century. The name of the Valley, and of the County, is most likely connected with this Native American group. It has also been attributed to General George Washington naming it in honor of John Skenandoa, an Oneida chief from New York who helped gain support of Oneida and Tuscarora warriors to aid the rebel colonists during the American Revolutionary War. Colonial Governor Gooch formally purchased the entire Shenandoah Valley from the Six Nations of the Iroquois by the Treaty of Lancaster in 1744. The Iroquois had controlled the valley as a hunting grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
