Thickshell Pondsnail
''Ladislavella utahensis'', common name the thickshell pondsnail, is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusc in the family Lymnaeidae, the pond snails. This species is endemic to Utah Lake in the United States. The last living snails were found in the early 1930s. Shell description The shell is globose, somewhat umbilicated and irregularly costate. The color of the shell is light horn and nearly pellucid. The spire is rather small and conical. The shell has from 4 to 4 and half convex whorls, that are somewhat flattened above, giving rather a shouldered appearance to the whorls. Whorls are rapidly increasing in size. The last whorl is inflated, with numerous rather marked transverse costae and minutely wrinkled. The suture is somewhat deep, regularly impressed. The aperture is elongately ovate, effuse, approaching patulous and pearly white within. The outer lip is simple and its margin is connected by a slight calcareous deposit. Th ...

Richard Ellsworth Call
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below). People named Richard Multiple people with the same name * Richard Andersen (other) * Richard Anderson (other) * Richard Cartwright (other) * Ri ...

Columella (mollusc)
The columella (meaning "little column") or (in older texts) pillar is a central anatomical feature of a coiled snail shell, a gastropod shell. The columella is often only clearly visible as a structure when the shell is broken, sliced in half vertically, or viewed as an X-ray image. The columella runs from the apex of the shell to the midpoint of the undersurface of the shell, or the tip of the siphonal canal in those shells which have a siphonal canal. If a snail shell is visualized as a cone of shelly material which is wrapped around a central axis, then the columella more or less coincides spatially with the central axis of the shell. In the case of shells that have an umbilicus, the columella is a hollow structure. The columella of some groups of gastropod shells can have a number of plications or folds (the columellar fold, plaits or plicae), which are usually visible when looking to the inner lip into the aperture of the shell. These folds can be wide or narrow, prominent ...

Endemic Fauna Of Utah
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 ...

Molluscs Of North America
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods ( ...

Proceeding Davenport Academy Of Natural Sciences
In academia and librarianship, conference proceedings is a collection of academic papers published in the context of an academic conference or workshop. Conference proceedings typically contain the contributions made by researchers at the conference. They are the written record of the work that is presented to fellow researchers. In many fields, they are published as supplements to academic journals; in some, they are considered the main dissemination route; in others they may be considered grey literature. They are usually distributed in printed or electronic volumes, either before the conference opens or after it has closed. A less common, broader meaning of proceedings are the acts and happenings of an academic field, a learned society. For example, the title of the ''Acta Crystallographica'' journals is New Latin for "Proceedings in Crystallography"; the ''Proceedings of the National Academy of Sciences of the United States of America'' is the main journal of that academy.

Sphaerium Dentatum
''Sphaerium'' is a genus of very small freshwater clams, aquatic bivalve molluscs in the family Sphaeriidae, known as the fingernail clams. The small clams in this genus are unusual in that many of them, such as ''Sphaerium corneum'', can climb around underwater on aquatic plants, using their long and strong foot.

Valvata Utahensis
The Utah roundmouth snail, also known as the Utah valvata or desert valvata, scientific name ''Valvata utahensis'', is a species of freshwater snail with a gill and an operculum, an aquatic gastropod mollusc in the family Valvatidae, the valve snails. This species of snail is endemic to the United States. The common name refers to the State of Utah. Taxonomy This species was first described as ''Valvata sincera'' var. ''utahensis'' by Richard Ellsworth Call (1856-1917, U.S.A.) in 1884 from specimens collected at Utah Lake, Utah (the type locality). R. E.

Lehi, Utah
Lehi ( ) is a city in Utah County, Utah, United States. It is named after Lehi, a prophet in the Book of Mormon. The population was 75,907 at the 2020 census, up from 47,407 in 2010. The rapid growth in Lehi is due, in part, to the rapid development of the tech industry region known as Silicon Slopes. The center of population of Utah is located in Lehi. Lehi is part of the Provo–Orem metropolitan area. History A group of Mormon pioneers settled the area now known as Lehi in the fall of 1850 at a place called Dry Creek in the northernmost part of Utah Valley. It was renamed Evansville in 1851 after David Evans, a local bishop in the Church of Jesus Christ of Latter-day Saints. Other historical names include Sulphur Springs and Snow's Springs. The land was organized into parcels of and new settlers received a plot of this size until the entire tract was exhausted. There was little water to irrigate the rich soil, so it became necessary to divert a portion of American Fork ...

Lake Utah
Utah Lake is a shallow freshwater lake in the center of Utah County, Utah, United States. It lies in Utah Valley, surrounded by the Provo-Orem metropolitan area. The lake's only river outlet, the Jordan River, is a tributary of the Great Salt Lake. Evaporation accounts for 42% of the lake's outflow, which leaves the lake slightly saline. The elevation of the lake is at above sea level. If the lake's water level rises above that, the pumps and gates on the Jordan River are left open. Recently the lake has been at a lower level because of a drought. The first European to see Utah Lake was Father Silvestre Vélez de Escalante in 1776. He stayed with the Timpanogots band of Ute Tribe for three days. The Timpanogots were later ethnically cleansed from the area by Mormon settlers between the 1850s and 1870s. The fish of the lake were overharvested by the settlers and subsequently restocked with non-native species. Although thirteen species of fish were native to the lake, only the ...
