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, …
aka: Clupeids
Herrings (Order Clupeiformes) belong to a large family (Clupeidae) of about 200 species within fifty-four genera of cosmopolitan ray-finned fishes that are mostly marine; a few inhabit freshwater, and some are anadromous—that is, they migrate up rivers from saltwater habitats for purposes of spawning. The family includes herrings, menhadens, sardines, and shads. Most herrings are small fishes, generally being less than 300 mm (12 in.), but some may reach 750 mm (30 in.). Many are valuable food fishes and are collected for production of fish meal and oil, protein concentrate, and fertilizer. Some commercially important species include Atlantic herring (Clupea harengus) found in the north Atlantic, Pacific sardine (Sardinops sagax), and Atlantic menhaden (Brevortia tyrannus). In the fossil record, clupeid …
aka: Dorothy Estheryne McFadden Clarke Hoover
Dorothy M. Hoover was a pioneer in the field of aeronautical mathematics and physics. The granddaughter of enslaved people, she overcame the significant obstacles facing African American women in the Jim Crow era of the twentieth century to earn advanced degrees in mathematics and physics. One of her greatest achievements in aeronautical research was her contribution to the development of the “thin sweptback tapered wing,” which revolutionized flight and became the aviation industry standard. Her life story was essentially unknown until she was briefly mentioned in the highly acclaimed book Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race (2016), by Margot Lee Shetterly. Hidden Figures, which was made …
John Wesley Huddleston is best known as a struggling farmer who found two diamonds on the surface of his field near Murfreesboro (Pike County) in August 1906 and made himself and his state famous. Soon after the discovery, he was recognized as the first person outside South Africa to find diamonds at an original volcanic source. In the process, he also became the controversial subject of numerous folk tales. A native of Pike County, John Huddleston was born in 1862 to David Fielding Huddleston and America White Huddleston. He had seven siblings before his mother’s death in the early 1870s and gained three step-sisters after his father’s remarriage to Francis Carey. In 1886, Huddleston wed Sarah A. Keys, the mother …
Conservationist Carl Glenn Hunter achieved prominence in two branches of the Arkansas outdoors—its fauna and its flora. Activities with wildflowers of the state made him a household name in Arkansas and beyond after his retirement as a wildlife biologist. Carl Hunter was born on August 30, 1923, in Little Rock (Pulaski County). He graduated from Little Rock High School (now Central High School) in 1941 and received a bachelor of science in agriculture degree from the University of Arkansas (UA) in Fayetteville (Washington County) in 1945. In college, Hunter worked part time for the Arkansas Game and Fish Commission (AGFC); he became a full-time employee in July 1945. He was one of the first hires of the agency after it …
Hydroelectric power is the electricity generated by the gravitational force of falling or flowing water through a turbine connected to a power generator. The three major types of hydropower facilities include reservoirs (high dams), in-stream (low dams), and pumped-storage. The most common type is the high dam, which creates significant reservoirs behind the dam (e.g., Hoover Dam). In 1882, the world’s first hydroelectric power station, located in Appleton, Wisconsin, produced 12.5 kilowatts of electrical power. Also in the early 1880s, a similar facility opened in New York City. Since these early facilities, hydroelectric power from the nation’s waterways has proliferated. Hydroelectric development in Arkansas can generally be grouped into three time periods—1924–1930; 1944–1973; and 1988–1999—and under three sponsoring agencies: Arkansas …
aka: Ants
Hymenopterans belong to the Phylum Arthropoda, Subphylum Labiata, Superclass Hexapoda, Class Insecta, and Order Hymenoptera. It is a large order of insects with over 150,000 described species comprising the sawflies, woodwasps, ichneumonids, chalcids, wasps, bees, and ants. In addition, there are over 2,000 extinct taxa. The order ranks third in the top five orders of insects in terms of total number of species. Many examples of this order are found in Arkansas, including the invasive fire ant. The Hymenoptera are divided into two suborders: the Symphyta (which have no waist) and the Apocrita (which have a narrow waist). Symphytans include the horntails, sawflies, and parasitic wood wasps. They have an unconstricted junction between the thorax and abdomen and a serrated …
aka: Catfishes
The Ictaluridae is a family of North American native fishes belonging to the Class Siluriformes. The Ictaluridae family also belongs to the Superorder Ostariophysi, the second-largest superorder of fish. This diverse group, present on all continents except Antarctica, contains 10,758 species—more than twenty-eight percent of known fish species in the world and seventy-two percent of all freshwater species. The family proper includes about seven genera and fifty-one species, some commonly known as bullheads, catfishes, and madtoms. As such, it is the largest family of freshwater fishes endemic to North America. In Arkansas, they are easily recognized as the only fishes in the state with four pairs (two on the snout, two on the end of maxillae, and four on the …
aka: Infogo
Information Galore, Inc., (a.k.a. Infogo) of El Dorado (Union County) was the first commercial Internet service provider (ISP) in Arkansas. Although the company was short-lived, it had a notable impact upon economic and educational initiatives in southern Arkansas, as well as parts of Texas and Louisiana. Infogo was founded by six individuals. John Gray was a world-famous geologist who was appointed to serve on the Arkansas Geological Commission (now Arkansas Geological Survey) several times by Governor Bill Clinton and who did work for the United Nations. Gray, along with Watt McKinney, Leon Wood, William L. (Billy) Cook, and Robert McKinney each invested $5,000. Joe Brazeal was a board member of ARKnet, the state’s educational computer network, and provided technical expertise …
Insects account for over half of all species described thus far worldwide, and they are the dominant form of life in terrestrial environments. It is estimated that 35,000 to 40,000 species of insects live in Arkansas, including around 10,000 species of beetles, around 9,000 species of flies, nearly 8,000 species of bees and wasps, and around 5,000 species of moths and butterflies. The remainder make up small orders such as the bristletails, mayflies, dragonflies and damselflies, cockroaches, mantids, termites, stoneflies, grasshoppers and crickets, earwigs, stick insects, book and bark lice, chewing and sucking lice, and true bugs and lacewings and their relatives. It is still not uncommon to find species in Arkansas that are unnamed and new to the scientific …
The Instructional Microcomputer Project for Arkansas Classrooms (IMPAC) was an innovative program that helped make emerging microcomputer technologies a key component of education in Arkansas. Influential across the nation, IMPAC was cited for excellence by Electronic Learning, Instructor Magazine, Pro Education, Information Week, the National Governors Association, the Congressional Office of Technology Assessment, Nelson B. Heller & Associates, and the Southwest Education Development Laboratory. A number of Arkansas educators made significant efforts in laying a foundation for the use of microcomputers in instruction, as well as providing for technical support and workshops for teachers and school administrators, K–12. New technologies of the 1980s included networking microcomputers, the progression toward online resources, computer-assisted instruction and multimedia, and instructional management software for …
aka: Alien Animals
An “invasive species” is defined as a species that is non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental problems or harm to human health. It typically matures and reproduces quickly and increases its geographic range rapidly, establishing populations and persisting over large areas. There are several reasons for this spread, including favorable environmental conditions and lack of natural predators, competitors, and diseases that normally regulate their populations, allowing invasive species to thrive. Invasive biota not only includes a variety of plants but also incorporates a wide variety of invertebrates and higher taxa from their native sites. As invasive species extend and dominate ecosystems, they invariably reduce native biodiversity …
aka: Exotic Plants
According to the U.S. Department of Agriculture (USDA) Forest Service, an invasive species is “a species that is non-native or alien to the ecosystem under consideration and whose introduction does or is likely to cause economic or environmental harm or harm to human health.” As such, there are a suite of negative effects from exotic plant species that include replacing rare and endangered species, hybridizing and competing with native species, killing trees and shrubs, altering hydrological patterns and stream function, preventing forest regeneration, possibly containing toxins that may be lethal to certain animals, changing fire patterns, and harboring pathogens. The cost to control invasive species and the damages they cause to property and natural resources in the United States is …
Shortly after experimental forests were authorized for the U.S. Forest Service (USFS)—an agency of the U.S. Department of Agriculture (USDA)—by the McSweeney-McNary Forest Research Act of 1928, the Ouachita National Forest (ONF) reached out to the USFS’s Southern Forest Experiment Station (SFES). The ONF staff members wanted the SFES to develop an experimental forest to help them learn about managing the shortleaf pine (Pinus echinata)–dominated forests of the Ouachita Mountains in Arkansas. In early 1931, the SFES dispatched a three-man crew to examine possible locations on the ONF, but they did not find any areas they thought were suitable for silvicultural research. The ONF and the USFS’s Washington DC office persisted, and a few years later the SFES suggested an experimental forest on a large tract of virgin and cutover timber along the Irons Fork …
aka: Campephilus principalis
Long believed to be extinct, the ivory-billed woodpecker (Campephilus principalis) was apparently rediscovered in the Big Woods of east Arkansas in 2004. More than sixty years after the last confirmed sighting in the United States, a research team announced on April 28, 2005, that at least one male ivory-bill survived in the vast bottomland swamp forest. Published in the journal Science, the findings included multiple sightings of the elusive woodpecker and frame-by-frame analyses of brief video footage. The evidence was gathered during an intensive year-long search in the Cache River and White River National Wildlife Refuges in eastern Arkansas, involving more than fifty experts and field biologists working as part of the Big Woods Conservation Partnership, led by the Cornell …
A tornado tore through north-central Arkansas on November 21, 1883, killing around eleven people, injuring dozens, and devastating Melbourne (Izard County) and LaCrosse (Izard County). The storm’s path started about a mile and a half southwest of Melbourne and moved to the northeast, the width of its devastation ranging from 200 yards to three-quarters of a mile wide. When it reached the Izard County seat of Melbourne at around 4:00 a.m., most people were in bed. A newspaper reported that “for five minutes nothing could be heard but the roar of the winds, the crash of falling buildings, drowning the shrieks of the terrified inhabitants.” The home of former sheriff and Melbourne merchant and cotton buyer John Hinkle, located two …
Douglas Arthur James served as a professor of biological sciences at the University of Arkansas (UA) in Fayetteville (Washington County) from 1953 to 2016. He was considered the authority of the birds of Arkansas, co-authoring Arkansas Birds with Joseph C. Neal in 1986, and became one of the state’s leading conservationists in the second half of the last century, helping to start the Arkansas Audubon Society in 1955 and the Arkansas Audubon Society Trust in 1972. He arranged the first meeting of what would become the Ozark Society, which was responsible for saving the Buffalo River from damming. Starting with studies of scrubland birds in northwestern Arkansas, James expanded to studying scrubland birds in Africa, Nepal, and Belize. He was …
aka: Archeognatha
The Archaeognatha (formerly Microcoryphia) are an order of apterygotes belonging to the Superclass Hexapoda, Class Insecta, Subphylum Labiata, and Phylum Arthropoda. They are known by various common names, such as jumping bristletails. The order is cosmopolitan and includes about 500 species (thirty-three species within twelve genera are Nearctic) in two families (Machilidae and Meinertellidae). None are currently evaluated as being a conservation risk. Little is known about the archaeognaths of Arkansas, as only Machiloides banksi and Pedetontus gershneri have been reported from the state, both from Mount Magazine (Logan County). Among extant arthropod taxa, they are some of the most evolutionarily primitive insects. The fossil record of Archaeognatha is sparse and often represented by fragmentary material. They first appeared in …
