Etheostoma Nianguae
The Niangua darter (''Etheostoma nianguae'') is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to Missouri, United States. It is found only in the Osage River Basin of central Missouri where its range historically included the Sac River, Pomme de Terre River, Niangua River, Big Tavern Creek, and Maries River. It is a federally listed threatened species of the United States. Description The Niangua darter is a slender, silvery-brown fish with about ten vertical dark bars with brown centers alternating with orange undulating lines. There are two small black spots at the base of the tail fin. The color is accentuated in breeding males which have bright orange and green bars along the flank and orange and green bands on the dorsal and tail fins. The maximum size of this fish is about but a more common size is . Lifecycle Adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and Fisheries science, fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservation movement, conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 187 ...

Fish Described In 1887
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a vertebrate, true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History Of Missouri
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Etheostoma
''Etheostoma'' is a genus of small freshwater fish in the family Percidae native to North America. Most are restricted to the United States, but species are also found in Canada and Mexico. They are commonly known as darters, although the term "darter" is shared by several other genera. Many can produce alarm pheromones that serve to warn nearby fish in case of an attack.Smith, R.J.F. (1992): Alarm signals in fishes. ''Reviews in Fish Biology and Fisheries, 2 (1): 33-63.'' Species The 157 recognized species in this genus are: * ''Etheostoma acuticeps'' R. M. Bailey, 1959 (sharphead darter) * ''Etheostoma akatulo'' Layman & Mayden, 2009 (bluemask darter) * '' Etheostoma artesiae'' ( O. P. Hay, 1881) (redspot darter) * '' Etheostoma asprigene'' ( S. A.

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maries River
The Maries River is a tributary of the Osage River in Pulaski, Maries, and Osage counties in the U.S. state of Missouri. The headwaters of the Maries arise just to the north and west of Dixon in northern Pulaski County (). The stream flows generally north into Maries County passing the communities of Brinktown and Venus. It passes under Missouri Route 42 west of Vienna and on into Osage County to the east of Argyle and Koeltztown. The stream enters a series of entrenched meanders and flows under U. S.
