Ictalurus Pricei
''Ictalurus pricei'', the Yaqui catfish, is a species of North American freshwater catfish native to Mexico and Arizona. Description The coloration of the Yaqui catfish is dark gray to black dorsally, and white to grayish beneath. The barbels of the catfish are jet-black except on the chin, where they are gray to whitened. The Yaqui catfish body is usually profusely speckled.Minckley, W.L. 1973. Fishes of Arizona. Arizona Game and Fish Department, Phoenix. pp. 179–180. A reddish coloration on the catfish is prominent beneath the head, as well as on the fins and tail. The adult size is up to . The spines on the pectoral and dorsal fins are shorter than those of a channel catfish (''Ictalurus punctatus'') of similar size. Etymology ''I. pricei'' was named in honour of William W. Price. Range The Yaqui catfish historically occurred in San Bernardino Creek as far up as San Bernardino Ranch, Arizona. An introduced population of catfish existed in the Monkey Springs Reservoir sy ...

San Bernardino National Wildlife Refuge
The San Bernardino National Wildlife Refuge is located on the U.S.-Mexico border in Cochise County, Arizona. Situated at elevation in the bottom of a wide valley, the refuge encompasses a portion of the headwaters of the Yaqui River, which drains primarily western Chihuahua and eastern Sonora, Mexico. The ranch was acquired by the U.S. Fish and Wildlife Service in 1982 to protect the water resources and provide habitat for endangered native fishes. Geography This area is part of the basin and range geologic region, characterized by linear mountain ranges which are separated by broad, flat basins. The region was impacted by relatively recent volcanic activity, leaving volcanic plugs and cinder cones visible throughout the San Bernardino Valley (Arizona). Earthquakes have further altered the region and helped allow the flow of many springs and seeps. All of these dynamic geological events have played major roles in shaping the valley, catching and storing crucial water, ...

Rio Sonora
Río Sonora (''Sonora River'') is a 402-kilometer-long river of Mexico. It lies on the Pacific slope of the Mexican state of Sonora and it runs into the Gulf of California. Watershed The Sonora River watershed covers of public land. Slopes range from steep orientations in the upper part of the watershed to more gradual topographies in the valleys. The Sonora River watershed is subdivided into six smaller watersheds.Diego Valdez-Zamudio, Peter F. Folliott (2005) Agroforestry Practices in the Sonora River Watershed, Mexico. AFTA 2005 Conference Proceedings pp. 1-4 Ecology Biotic communities found within the watershed in order of importance by the area covered are the Sinaloan thornscrub, the plains of Sonora subdivision, semidesert grasslands, the Madrean evergreen woodland, and the central gulf coast subdivision. Average annual precipitation is which occurs in two seasons, late summer-early fall and winter-early spring. Physician naturalist Edgar Alexander Mearns' 1907 report o ...

Taxa Named By Cloudsley Louis Rutter
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Sierra Madre Occidental
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as ''Biota (ecology), biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontology, Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology '':wikt:fauna, Fauna'' comes from the name Fauna (deity), Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan (god), Pan, and ''panis'' is the Modern Greek equivalent of fauna (πα� ...

Fish Of The United States
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Freshwater Fish Of Mexico
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ictalurus
''Ictalurus'' is a genus of North American freshwater catfishes. It includes the well-known channel catfish (''Ictalurus punctatus'') and blue catfish (''Ictalurus furcatus''). The catfish genome database (cBARBEL) is a database for the genetics of ''Ictalurus'' species. Distribution Members of this genus are primarily found in the Mississippi River basin & peninsular Florida, and range south to southern Mexico, where several range-restricted species are known. Some species, such as the channel and blue catfish, have been introduced to parts of North America west of the Rocky Mountains and east of the Appalachian Mountains, where they are otherwise not native. However, the fossil species ''Ictalurus countermani'', known from the Miocene of Maryland, suggests that this genus did naturally inhabit the Atlantic-draining rivers east of the Appalachians during the Neogene. Species Currently, 10 species in this genus are recognized: * '' Ictalurus australis'' ( Meek, 1904) (Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monkey Springs Reservoir
Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes. Thus monkeys, in that sense, constitute an incomplete paraphyletic grouping; alternatively, if apes (Hominoidea) are included, ''monkeys'' and ''simians'' are synonyms. In 1812, Étienne Geoffroy grouped the apes and the Cercopithecidae group of monkeys together and established the name Catarrhini, "Old World monkeys" ("''singes de l'Ancien Monde''" in French). The extant sister of the Catarrhini in the monkey ("singes") group is the Platyrrhini (New World monkeys). Some nine million years before the divergence between the Cercopithecidae and the apes, the Platyrrhini emerged within "monkeys" by migration to South America likely by ocean. Apes are thus deep in the tree of extant and extinct monkeys, and any of the apes is distinctly closer related to the Cercopithecida ...
