Gars

aka: Garfish
aka: Garpikes
Gars are a primitive group of euryhaline fishes dating back to the late Jurassic to early Cretaceous Period, about 150 million years ago. Gars are one of the most recognizable fishes because of their slender torpedo-shaped bodies, ganoid scales, and long snouts with numerous teeth. Dorsal and anal fins are set far back on the body, and the caudal fin is rounded, with a condition known as abbreviate-heterocercal. Gars are unusual among fishes in that their vascularized swim bladders can function as lungs; they must surface periodically to take a gulp of air. Arkansas hosts four gar species: the alligator gar (Atractosteus spatula), spotted gar (Lepisosteus oculatus), longnose gar (L. osseus), and shortnose gar (L. platostomous). Fossilized gar specimens have …

Gastrotrichs

aka: Hairybacks
The Phylum Gastrotricha (commonly called “hairybacks”) comprises about 800 species of marine, brackish, and freshwater microscopic invertebrates. Twelve genera and fewer than 100 species of freshwater gastrotrichs are known from North America. However, in North America, perhaps 75 to 90 percent of the probable diversity of freshwater gastrotrichs species are undescribed. Gastrotrichs are widely distributed cosmopolitan organisms that are divided into two orders: the Macrodasyida (with nine families), which, except for two freshwater species (Marinellina flagellata and Redudasys fornerise), are marine, and the Chaetonotida (seven families), some of which are marine, estuarine, and semi-terrestrial forms, while others are primarily found in freshwater. The Chaetonotida can be further broken down into two suborders: the Multitubulatina (Nesodasys) and the Paucitublatina (Chaetonotus, Dasydytes, …

Geckos

Geckos are lizards that belong to the Class Reptilia, Order Squamata, Suborder Sauria (Lacertilia), and Infraorder Gekkota within seven families, including Carphodactylidae (seven genera, thirty species), Diplodactylidae (twenty-five genera, 137 species), Eublepharidae (six genera, thirty species), Gekkonidae (fifty-four genera, 1,264 species), Pygopodidae (eight genera, thirty-five species), Phyllodactylidae (nine genera, 100 species), and Sphaerodactylidae (twelve genera, 200 species). By far, the true geckos (Gekkonidae) are the largest family of lizards. Many common geckos are members of this family, including dtellas (Gehyra), house geckos (Hemidactylus), true geckos (Gekko), and day geckos (Phelsuma). Geckos are cosmopolitan in distribution and are particularly species-rich in the tropics. At least one type of gecko is found in Arkansas. Geckos probably evolved in the Lower Cretaceous, and …

Still University—in Kirksville, Missouri, having studied under the founder of osteopathy, A. …

Goldeyes and Mooneyes

aka: Mooneyes and Goldeyes
aka: Hiodontid Fishes
North American freshwater fishes of the family Hiodontidae (order Hiodontiformes or Osteoglossiformes) include the goldeye (Hiodon alosoides) and mooneye (H. tergisus). The goldeye ranges from James Bay (bordering the provinces of Ontario and Quebec) in Canada and the Mississippi River basins from the Northwest Territory to western Pennsylvania and Ohio south to Louisiana. In Arkansas, H. alosoides is found sporadically in lakes and the larger turbid rivers of the state, including the Arkansas and Mississippi, and the smaller Black River. The mooneye (also called the “freshwater tarpon”) ranges from the St. Lawrence–Great Lakes, Mississippi River, and Hudson Bay basins from Quebec and Alberta, Canada, east to western North Carolina and south to Louisiana. In Arkansas, H. tergisus occurs in large …

Good, Mary Lowe

Mary Lowe Good was a renowned chemist, industrial innovator, professor, and government leader.

Government Free Bathhouse

The Government Free Bathhouse in Hot Springs (Garland County) provided free baths to the indigent, sick, and injured who sought access to the local thermal springs, which were thought to have medicinal properties. Spurred into existence by an act of Congress in 1878, the free bathhouse operated until 1957. In 1832, the federal government made the hot springs of Arkansas a federal reservation Businesses arose to offer food, lodging, and entertainment, but access to the water was free. After the Civil War, businesses tried to take ownership of the hot water. This enraged visitors, who felt that everyone had a right to access the water for no charge. On December 16, 1878, Congress passed compromise legislation that reaffirmed federal ownership …

Greers Ferry Dam and Lake

Greers Ferry Dam on the Little Red River, approximately three miles north of Heber Springs (Cleburne County), is a concrete dam built between 1959 and 1962. The dam’s primary function is flood control, but it also serves as a hydroelectric power plant. Greers Ferry Lake, created as a result of the dam, is a popular recreational destination. The flow of the Little Red River was uncontrolled during the first half of the twentieth century, resulting in almost yearly flooding downstream; high water levels in the Little Red River could compound flooding problems further downstream along the White River. In 1938, Congress passed the Flood Control Act, which authorized the U.S. Army Corps of Engineers to build dams on most of …

Grotto Salamander

aka: Eurycea spelaea
aka: Ghost Lizard
aka: Ozark Blind Salamander
The grotto salamander (Eurycea spelaea) is a species of lungless salamander in the Phylum Chordata, Subphylum Vertebrata, Class Amphibia, Order Caudata, and Family Plethodontidae. It was originally described as Typhlotriton spelaeus but is now considered a member of the genus Eurycea. It is endemic to wet caves, sinkholes, and karst regions beneath the Springfield and Salem Plateaus of the Ozark Mountains of 120 individual sites in northern Arkansas, 124 sites in southwestern Missouri, forty-three sites in northeastern Oklahoma, and one county (Cherokee) in extreme southeastern Kansas. Its natural habitats are freshwater springs, inland karsts, and caves. It is not listed by the federal government as endangered or threatened, but it is vulnerable to changes in groundwater quality and a reduction …

Haemogregarines

Haemogregarines are protist parasites that belong to the Phylum Apicomplexa, Class Conoidasida, Order Eucoccidiorina, and Suborder Adeleorina, and include the following seven families: Adeleidae, Dactylosomatidae, Haemogregarinidae, Hepatozoidae, Karyolysidae, Klossiellidae, and Legerellidae. There are two major genera, Haemogregarina and Hepatozoon, in addition to several minor ones, including Babesiosoma, Bartazoon, Cyrilia, Dactylosoma, Desseria, Hemolivia, and Karyolysus. As a group, these parasites are cosmopolitan in their range of infected hosts (such as turtles, crocodiles, birds, reptiles, and mammals) and geographic distribution. In general, haemogregarines sensu lato (meaning, in a broad sense) are elongate to fusiform ovoidal organisms that occur within the erythrocytes (red blood cells) of various animals, mostly poikilothermic vertebrates (animals whose internal temperatures vary widely). They form a group of diverse …

Handywagon

The Handywagon, built in 1964 for the Arkansas Louisiana Gas Company (Arkla), was intended as an economical vehicle for use by the company’s Gaslite and domestic appliance servicers, meter readers, collectors, and meter setters. The small wagon was designed to be easily reparable and average thirty-five miles per gallon. In mid-1963, Arkla board chairman Wilton “Witt” R. Stephens asked company lawyer Raymond Thornton to design a utility vehicle that could operate economically, have a 900-pound load capacity, weigh less than a ton and a half, and be company-built. In 1964, Thornton chose Ed Handy, a company construction engineer, to collaborate with him on the project. After much research, the two men found the power train they needed in Holland. Van …

Harvestmen

aka: Daddy Long-Legs
aka: Granddaddy Long-Legs
Harvestmen belong to the Phylum Arthropoda, Subphylum Chelicerata, Class Arachnida, and Order Opiliones. They represent the third most diverse order in Arachnida. The order Opiliones includes five suborders as follows: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi. They are often referred to as “daddy long-legs.” They are found throughout the world (except Antarctica), and there are over 6,650 species. Their common name is derived from the fact that they are common during the harvesting season. They are traditionally akin with the Order Acari (ticks and mites) or the Novogenuata (the Scorpiones, Pseudoscorpiones, and Solifugae); however, others suggest the Opiliones forms a clade with the scorpions and two smaller orders. As such, they are considered the sister group of scorpions. In addition, …

Health and Medicine

Arkansas long had a reputation for being sickly because much of the state supported large mosquito populations, carrying malaria, yellow fever, and other diseases. Modern medicine, a largely nineteenth-century creation, arrived late, and throughout the twentieth century, diseases eradicated elsewhere continued to flourish. Only after World War II did sharp improvements in health occur, but the Delta lagged far behind. Problems in health and medical programs were compounded in part because many Arkansans deliberately engaged in forms of risky behavior such as tobacco use and unhealthy diets. Prehistoric Arkansas The first settlers more than 10,000 years ago brought to the New World only a few major illnesses. One was tuberculosis, evidence of which is visible in bones from burial sites. …

Hemipterans

aka: True Bugs
Hemipterans, or true bugs, belong to the Phylum Arthropoda, Superclass Hexapoda, Class Insecta, Order Hemiptera, and four suborders: Auchenorrhyncha, Coleorrhyncha, Sternorrhyncha, and Heteroptera. Hemiptera is the largest order of hemimetabolous insects (those not undergoing complete metamorphosis), although male scale insects (Coccoidea) do undergo a form of complete metamorphosis. The number of species in the order is about 75,000, with a great diversity of forms, including aphids, cicadas, leafhoppers, planthoppers, and shield bugs. The three largest families of Heteroptera are Miridae (plant bugs), Lygaeidae (seed bugs), and Pentatomidae (stink bugs). The largest family, Miridae, contains major insect pests and predatory groups that can be used as biological control agents. Although hemipterans inhabit a wide variety of habitats, most are generally terrestrial, …
