Abernathy Spring

Abernathy Spring is a mineral spring located in Polk County, 2.8 km (1.75 mi.) east of the unincorporated community of Big Fork on the north side of State Highway 8. Elevation is 335 meters (1,099 ft.). The spring was owned by Rufus J. Abernathy (1856–1932), who resided at Big Fork and is buried at the Pleasant Grove Cemetery just outside of town and east of the spring. Water from the spring drains into adjacent Big Fork Creek (a tributary of the Ouachita River) and, at one time, was used for domestic purposes, such as for water supply and to keep food cold. There are actually two springs at this location—the primary one is a 75 cm (29.5 in.) diameter galvanized …

Abington, Eugene Hardeman (E. H.)

Eugene Hardeman (E. H.) Abington, a physician, practiced medicine and pharmacy in Arkansas and Oklahoma for more than sixty years and wrote about his career in his 1955 book Backroads and Bicarbonate: The Autobiography of an Arkansas Country Doctor. From 1927 to 1937, he served as the first president of the Junior Agricultural School of Central Arkansas (which later became Arkansas State University–Beebe), a school established by his older brother W. H. Abington. Born on April 20, 1873, in Des Arc (Prairie County) and raised in Beebe (White County), E. H. Abington was the second son in the farming family of William T. Abington and Mary Jane Plant Abington. He had one older sister and one older brother, William Henry …

Abington, William Henry

William Henry (W. H.) Abington, a physician and a Democratic politician, served as a state senator and a state representative in the Arkansas General Assembly from 1923 to 1951. From 1929 to 1931, he was speaker of the Arkansas House of Representatives. As a legislator, he supported medically oriented legislation and established the Junior Agricultural School of Central Arkansas (now Arkansas State University–Beebe) in 1927. W. H. Abington was born on January 2, 1870, in Collierville, Tennessee, to the farming family of William T. Abington and Mary Jane Plant Abington. He had an older sister and a younger brother. His family moved to White River (Prairie County) in 1870 but had relocated to Union (White County) by 1880. His brother, …

Abortion

Abortion is defined as either a spontaneous early ending of a pregnancy (a.k.a. miscarriage) or an induced early ending of a pregnancy. In Arkansas, amidst changes in abortion’s legal status over the years, women have sought abortions for various reasons, including maternal and fetal health problems, financial concerns, and the stigma of single pregnancy. On March 9, 2021, the Governor Asa Hutchinson signed into law a bill that outlawed all abortions, with no exception for the termination of pregnancies due to rape or incest, save those performed to save the life of the mother in a medical emergency; this law was designed to set up legal challenges to the U.S. Supreme Court precedent of Roe v. Wade and came two years after …

Acanthocephalans

aka: Spiny-Headed Worms
aka: Thorny-Headed Worms

These cylindrical metazoan worms, superficially similar to nematodes, belong to the phylum Acanthocephala and include four classes, ten orders, twenty-six families, and about 1,300 species. Recent molecular studies suggest that Rotifera (rotifers) and Acanthocephala are phylogenetically related sister groups. Adult members are highly specialized, dioecious (having distinct male and female colonies, as opposed to hermaphroditic) parasites of the intestinal tract of a variety of vertebrates (but not generally humans). They cause serious disease fairly rarely. The life cycle involves at least two hosts, either an aquatic intermediate host (Amphipoda, Copepoda, Isopoda, and Ostracoda) or terrestrial intermediate hosts including insects, crustaceans, and myriapods. Fishes, amphibians, reptiles, birds, and mammals serve as definitive hosts. Acanthocephalans range from 0.92 to 2.4 millimeters long …

Act 1220 of 2003

aka: Childhood Obesity Act

Act 1220 of 2003, which launched comprehensive efforts to curb childhood obesity in Arkansas, established one of the nation’s first statewide, school-focused initiatives to help children reach and maintain a healthy weight. Shaped largely by key legislators, including Senator Hershel Cleveland, with input from state and national public health experts, the act passed through the Arkansas General Assembly with strong support from the House and Senate under the administration of Governor Mike Huckabee. After passage, however, several components of the act faced vocal opposition. Opponents feared the largely unfunded mandates would strain educational and healthcare systems in addition to shaming overweight students. This vocal opposition prompted changes to the act in the years following its passage. Subsequent evaluation of Act …

Act 911 of 1989

aka: Arkansas Conditional Release Program

Act 911 of 1989 pertains to the evaluation, commitment, and conditional release of individuals acquitted of a crime when found Not Guilty by Reason of Mental Disease or Defect. The evaluation process, completed by a certified forensic psychologist or psychiatrist, assesses the defendant’s fitness to proceed to trial and, if the defendant is found fit to proceed, mental state at the time of the crime. If the defendant is found not fit to proceed, the proceedings against the defendant are suspended, and the court may commit him/her for detention, care, and treatment at the Arkansas State Hospital (ASH) until restoration of fitness to proceed. Once fit to proceed, a re-evaluation includes an assessment of mental state at the time of …

Adams, Elizabeth Lucille (Betty Lu) Hunter Sorensen

Elizabeth Lucille (Betty Lu) Hunter Sorensen Adams was a pioneer occupational therapist at Arkansas Children’s Hospital as well as the founder and second president of the Arkansas Occupational Therapy Association and its first delegate to a national conference. She has also distinguished herself as an artist and writer. Betty Hunter was born on February 3, 1926, in Tokyo, Japan, the daughter of Joseph Boone and Mary Cleary Hunter, both missionaries; she has one brother. The Hunter family came to Arkansas when, due to the Depression, there were no funds to return to missions. They lived in Little Rock (Pulaski County), where her father founded Pulaski Heights Christian Church. In 1940, the family left Little Rock to return to Japan but …

AIDS

By 2007, a cumulative 4,119 Arkansans had been diagnosed with Acquired Immunodeficiency Syndrome (AIDS), the disease caused by the Human Immunodeficiency Virus (HIV), with 196 of those cases being newly diagnosed in that year. Of all cases diagnosed in Arkansas, more than eighty percent were among men, fifty-seven percent were among whites, and forty percent were among African Americans. However, among cases newly diagnosed in 2007, the majority (fifty-five percent) were among African Americans, with only thirty-seven percent of new cases being among whites. This trend follows national rates of proportionally more cases being diagnosed among African Americans and other minorities. Of those 4,119 diagnosed with AIDS, more than 2,000 were people living with AIDS as of the end of …

Alford, Thomas Dale

Thomas Dale Alford was a prominent Arkansas ophthalmologist, Episcopalian, radio announcer, civic leader, and politician remembered largely as a leader of opposition to federally mandated desegregation during the crisis at Central High School in Little Rock (Pulaski County). Alford’s role as a leading segregationist came first through his seat on the Little Rock School Board and then as the “Segregation Sticker Candidate” who upset incumbent Democratic U.S. Representative Brooks Hays after a notorious ten-day write-in campaign in the 1958 election for the Fifth Congressional District of Arkansas. Dale Alford was born near Murfreesboro (Pike County) on January 28, 1916, the son of T. H. Alford and Ida Womack Alford, both of whom were itinerant school teachers. His father ultimately became …

Algae

Arkansas has a very diverse assemblage of algae. The majority of the research conducted on algae in the state is published in the Arkansas Academy of Science’s journal, but some is available in other journals and government publications. Most of the studies have been performed in northern Arkansas by Dr. Richard L. Meyer from the University of Arkansas (UA) in Fayetteville (Washington County). He and his graduate students undertook many studies that were developed into MS and PhD theses. The studies were performed in rivers (Buffalo, White, Arkansas, and Mississippi rivers), a few lakes (Lake Chicot, Lake Fort Smith, and Lake Fayetteville), a few smaller ponds, a stream, and an agricultural rice field. Three studies were done in Hot Springs …

Alligator Snapping Turtle

The alligator snapping turtle (Macrochelys temminckii) is North America’s largest freshwater turtle. This turtle is found primarily in major rivers, streams, swamps, and oxbow lakes throughout much of the south-central United States—all around the states of Arkansas and Mississippi and in portions of Texas, Oklahoma, Kansas, Missouri, Illinois, Iowa, Georgia, and Florida. Alligator snapping turtles have distinct morphological features that distinguish them from their closest cousin, the snapping turtle (Chelydra serpentina). For example, the dorsal shell, or carapace, of the alligator snapping turtle has three prominent keels (ridges on the carapace), whereas the keels of the snapping turtle are low and become less conspicuous with age. The tails of both species have three rows of tubercles (warty projections), but these scales …

Alzheimer’s Arkansas

Alzheimer’s Arkansas is an incorporated nonprofit organization governed by a local board of directors consisting of family members of Alzheimer’s patients, business and community leaders, and healthcare professionals. The organization offers an array of programs and services, including respite care, home improvements (such as wheelchair ramps), and educational tools. All services are funded through special events, grants, memberships, memorials, and other contributions; eighty-five percent of all contributions received are spent in Arkansas. Alzheimer’s Arkansas was founded as the Alzheimer’s Support Group of Central Arkansas in 1984. In 1986, the group affiliated with the national Alzheimer’s Association. In June 2002, however, the Alzheimer’s Arkansas Board of Directors elected to withdraw from the national association and become an independent nonprofit organization. Several …

American Alligator

The American alligator (Alligator mississippiensis) belongs to the class Reptilia, order Crocodylia, superfamily Alligatoroidea, and family Alligatoridae. There are seven species in the family endemic to the New World tropics, with an eighth species occurring in the warmer temperate regions of China. The American alligator is endemic to the southeastern coastal plain of the United States, where it inhabits freshwater wetlands such as streams, reservoirs, ponds, lakes, coastal marshes, bayous, oxbows, and cypress swamps associated with larger rivers in parts of Alabama, Arkansas, Florida (and some Florida Keys), Georgia, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Texas, and Virginia; it also occurs in the lower Rio Grande Valley of Texas south of San Antonio, and farther south into the thornscrub …

American Burying Beetle

aka: Giant Carrion Beetle

The American burying beetle (Nicrophorus americanus)—which belongs to the Phylum Arthropoda, Class Insecta, Order Coleoptera, and Family Silphidae—is a carnivorous beetle that feeds on and requires carrion to breed. It is the largest North American carrion beetle. In July 1989, it was placed on to the federal Endangered Species List; the International Union for Conservation of Nature (IUCN) currently lists the species as critically endangered. However, the U.S. Fish and Wildlife Service has proposed to downlist N. americanus from endangered to threatened under the Endangered Species Act. In the few states in which it is found, including Arkansas, it is ranked S1 (critically imperiled) by NatureServe. The decline of N. americanus has been attributed to habitat loss, alteration, and degradation, …

American Eel

The American eel (Anguilla rostrata) belongs to the order Anguilliformes and family Anguillidae. Common names include Atlantic eel, common eel, freshwater eel, silver eel, yellow-bellied eel, green eel, black eel, bronze eel, elver, whip, and easgann. This family includes about eighteen facultative catadromous species of eels. The American eel ranges from Greenland and Iceland and all the drainages of eastern North America along the Atlantic and Gulf slopes west to New Mexico and south to Venezuela and islands of the Caribbean and West Indies across a latitudinal range of 5 to 62° N. In North America, A. rostrata occurs inland from eastern Canada to the Great Lakes, in the headwaters of many Atlantic and Gulf slope rivers, and in the …

American Red Cross

The American Red Cross has been active in Arkansas since the second decade of the twentieth century. As an organization operated principally through volunteer labor, the Red Cross has assisted citizens of Arkansas through floods, droughts, and fires, as well as training Arkansans in emergency response and in health and safety. Three chapters of the Arkansas Red Cross serve various regions in the state of Arkansas, meeting the needs of Arkansans and disbursing help from Arkansans to meet needs all over the world. The American Red Cross was founded in Washington DC on May 21, 1881, with Clara Barton as its first director. The first Red Cross chapters founded in Arkansas began during World War I, when the number of …

Ammonites

aka: Ammonoids

Ammonites are an extinct group of marine invertebrates in the Phylum Mollusca, Class Cephalopoda, and Subclass Ammonoidea. The subclass can be divided into six orders as follows: Agoniatitida (present in the Lower Devonian–Middle Devonian), Clymeniida (Upper Devonian), Goniatitida (Middle Devonian–Upper Permian), Prolecanitida (Upper Devonian–Upper Triassic), Ceratitida (Upper Permian–Upper Triassic), and Ammonitida (Lower Jurassic–Upper Cretaceous). The name “ammonite,” from which the common name is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resembles tightly coiled ram’s horns. These molluscs are more closely related to living coleoids (e.g., cuttlefish, octopuses, and squid) than they are to shelled nautiloids, such as extant chambered Nautilus species. The earliest ammonites originated from within the bactritoid nautiloids, appearing during the Devonian …

Amphibians

Arkansas has within its borders a modest assemblage of salamanders, frogs, and toads, which are taxonomically grouped in the class Amphibia and, therefore, are commonly called amphibians. Amphibians were the first tetrapods (four-legged vertebrates) to walk on land, having come from an early-evolving group of lobe-finned fishes nearly 360 million years ago. Today’s amphibians possess a mostly bony skeleton with a strong “backbone” comprising a series of interlocking vertebrae. Salamanders are termed caudates because they possess a tail in both the juvenile and adult forms, whereas frogs and toads (collectively called anurans) lack tails as adults even though the larvae (tadpoles) possess them. The study of amphibians has been traditionally linked with the study of reptiles in the professional field …

Amphipods

aka: Scuds

Amphipods belong to the Phylum Arthropoda, Class Crustacea, Subclass Malacostraca, and Order Amphipoda. The Malacostraca contains seventy percent of all known crustaceans. Over 10,000 species of amphipods are currently recognized. Twenty species of amphipods are known from Arkansas, with most being found in groundwater environments. Traditionally, amphipods have been placed in four suborders: the Caprellidea, Gammaridea, Hyperiidea, and Ingolfiellidea. The Gammaridea, which contains the majority of species, includes all the freshwater and semi-terrestrial taxa. The Hyperiidea includes the pelagic amphipods, which are associated with other planktonic forms such as gelatinous zooplankton (medusae and ctenophores). Hyperiids are usually characterized by very large eyes, although some forms, like gammarideans, have normal-sized eyes. Hyperiid members are a polyphyletic group, and it is thought …

Annelids

aka: Segmented Worms

The phylum Annelida consists of over 22,000 living species of segmented worms. They include earthworms, leeches, and ragworms. Annelids are bilaterally symmetrical, triploblastic invertebrates that inhabit a wide diversity of habitats, including marine environments such as tidal zones, hydrothermal vents, lotic and lentic freshwater habitats, and moist terrestrial habitats. The term “Annelida” originated in 1802 from French naturalist, Jean-Baptiste Lamarck’s (1744‒1829), annélides. Several species of annelids can be found in Arkansas. The overall classification of the phylum is undergoing significant revisions and has not yet been stabilized completely. Phylogenomic and other molecular phylogenetic analyses have shown that taxonomic groupings previously based on morphology in many cases are invalid. The phylum was previously divided into three classes as follows: Polychaeta (marine, …

Apicomplexans

aka: Sporozoans

The protistan Phylum Apicomplexa (formerly Sporozoa) contains a tremendous variety of obligate intracellular parasites infecting many different organisms, including humans. As a group, these parasites are cosmopolitan in their range of infected hosts and geographic distribution. They include such diverse parasites as coccidians, cryptosporids, gregarines, haemosporoids, and piroplasms. All are united, not by their biology or life histories, but morphologically by the presence of a unique structure called an apical complex. The classification scheme that cites this structure has a practical purpose to sort this diversity in a functional manner that can: (1) be easily understood and, (2) serve a utilitarian purpose by non-specialists. However, the field of classifying Apicomplexa is in flux; indeed, its taxonomy has changed throughout the …

Arachnids

Arachnids belong to Chelicerata, one of four groups of living arthropods. The other three groups are Crustacea, Myriapoda (centipedes and millipedes), and Hexapoda (insects and relatives). There are eleven living arachnid orders, and Arkansas has representatives of five of these including Scorpiones (scorpions), Pseudoscorpiones (pseudoscorpions), Opiliones (harvestmen), Aranea (spiders), and Acari (mites). Overview of Arachnids Arachnid bodies are divided into two main regions called the prosoma (cephalothorax) and opisthosoma (abdomen). These regions have been subdivided in some groups (e.g., solifugids, scorpions). The prosoma holds six pairs of appendages. Unlike in all other arthropods, the first appendages in chelicerates are not sensory antennae but pincer-like mouthparts known as chelicerae (hence the subphylum name). Behind the chelicerae, there are two pedipalps that …

Arkansas Academy of Science

The Arkansas Academy of Science (AAS) aims for the promotion of knowledge in the fields of science, engineering, technology, and mathematics and the diffusion of that knowledge. The AAS is the Arkansas component of the American Association for the Advancement of Science. The first meeting of the Arkansas Academy of Science occurred in 1917. The AAS was created by a group of Arkansas scientists who wanted to develop a vehicle for the promotion of science as well as dissemination of research by Arkansas scientists. This was achieved by organizing annual meetings and publishing a journal. The annual meetings include sessions in which fledgling scientists present their findings in areas of biological and physical science as well as engineering, mathematics, and …

Arkansas Association of Black Psychology Professionals

The Arkansas Association of Black Psychology Professionals (AABPP), founded in January 2011, is a professional organization of African American psychology professionals in Arkansas. AABPP was established to: (1) form an affiliation of Black psychology professionals; (2) promote professional development for its members; (3) promote cultural competency and awareness of mental health issues unique to individuals of African descent; (4) promote mental health education, social change, and advocacy within the Black community; and (5) support and mentor students to pursue careers in the mental health professions. AABPP is the first organization of African American psychology professionals in Arkansas. For decades, African Americans from Arkansas pursuing a career in psychology had to leave the state for educational and employment opportunities. It was …

Arkansas Biosciences Institute (ABI)

The Arkansas Biosciences Institute (ABI) was created as the major research component set forth in the Tobacco Settlement Proceeds Act of 2000, passed by sixty-four percent of Arkansas voters in the general election on November 7, 2000. The primary goal of ABI is to improve the health of Arkansans through new and expanded agricultural and biomedical research initiatives, and, to that end, it operates as a partnership in health-related research with its five member institutions: Arkansas Children’s Hospital Research Institute, Arkansas State University (ASU), the University of Arkansas Division of Agriculture, the University of Arkansas (UA) in Fayetteville (Washington County), and the University of Arkansas for Medical Sciences (UAMS). The Tobacco Settlement Proceeds Act of 2000 directed the State of …

Arkansas Black Apple

The Arkansas Black Apple is recognized by early sources as having been first produced in 1870 in the orchard of a Mr. Brathwaite, which was then about one and a half miles northwest of Bentonville (Benton County). The fruit, a variety of Winesap, is usually round and of medium size. The flesh is yellow, fine grained, crisp, juicy, and aromatic, while the skin is dark red to black, hence its name. It ripens in October or November, and the fruit keeps well though the storage season of two to four months. Originally, the tree was thought to be a seedling of the Winesap Apple. It is a true native apple grown in the Ozarks of both Arkansas and Missouri. There …

Arkansas Blood Labeling Bill

aka: HB 385

On April 2, 1959, Governor Orval E. Faubus signed HB 385 (Blood Labeling Bill) into law, requiring blood banks to label the donor’s race. The bill was introduced by N. B. Murphy of Ashley County, who later called for the repeal of the bill in 1969. Faubus claimed the law would ease the minds of the “great majority” who feared transmission of sickle-cell anemia through blood transfusions. Despite thorough medical research stating that sickle-cell anemia cannot be spread through blood transfusions and knowing “it is hereditary, and can be transmitted from one person to another only by intermarriage which results in the birth of children,” Faubus and the “great majority” believed there was “always room for error” and that the …

Arkansas Children’s Colony

aka: Conway Human Development Center

Dedicated on October 4, 1959, the Arkansas Children’s Colony was a state-supported center that served Arkansas’s mentally handicapped children. The colony, set on a little over 400 donated acres in Conway (Faulkner County), provided a school and a home away from home for as many as 1,000 developmentally disabled, school age children. Governor Orval Faubus lobbied strongly for funds to build a facility to serve the state’s mentally challenged children. On January 25, 1955, the Arkansas General Assembly created Act 6, which engendered Arkansas’s first facility to serve such children. Arkansas was the forty-eighth state to open such an institution. A donation of $1,200 was made to the facility, and workers began construction in 1958. Less than two years later, …

Arkansas Children’s Hospital (ACH)

Arkansas Children’s Hospital (ACH), with facilities in Little Rock (Pulaski County) and Springdale (Washington and Benton counties),is the only pediatric hospital in Arkansas and is among the ten largest children’s hospitals in the United States. Pediatric specialists routinely treat patients from other states and occasionally other countries. Prior to becoming an independent children’s hospital, ACH was an orphanage. In February 1912, Horace Gaines Pugh of Little Rock helped establish the organization that would become Arkansas Children’s Home Society. Pugh, an Illinois native, moved to Little Rock in 1896, where he worked in real estate and eventually opened his own printing house, H. G. Pugh & Company. Pugh’s early mission was to found a haven for children who were orphaned, neglected, or …

Arkansas Country Doctor Museum (ACDM)

The Arkansas Country Doctor Museum (ACDM) in Lincoln (Washington County), in rural northwest Arkansas, is located in an eleven-room combined house, office, and four-bed clinic used successively by three physicians from 1936 until 1973. It features numerous examples of vintage medical equipment and a Hall of Honor highlighting notable pioneer-area physicians and their contributions to patients and the community. A carriage house and an educational building are also part of the museum. Dr. Harold Boyer, son of the last doctor to use the clinic, established the ACDM in 1994 to honor his father and other country doctors and the values they embodied. Herbert L. Boyer graduated from the University of Arkansas Medical Department, now the University of Arkansas for Medical …

Arkansas Darter

aka: Etheostoma cragini

Arkansas darter (Etheostoma cragini) populations are scattered among some small, spring-fed tributaries of the Arkansas River basin in Colorado, Kansas, Oklahoma, Missouri, and Arkansas. This fish species is rare in Arkansas, being found only in a few spring runs in the Illinois River basin of Benton and Washington counties. The small streams occupied by Arkansas darters are characterized by slow current and silt substrates. The darters shelter in watercress and other aquatic plants, overhanging or flooded terrestrial vegetation, and even in the loose silt of the stream bottom. In some places, they have been observed to move down into larger streams, but this has not been so in Arkansas. They grow to a maximum size of around two inches and …

Arkansas Department of Health (ADH)

The Arkansas Department of Health (ADH) exercises supervision over all matters pertaining to the health of Arkansas’s citizens, from food safety and sanitation to hospitals and medicine. The first state board of health was actually the Little Rock (Pulaski County) board of health, which sprang into action in 1878 in the face of a yellow fever epidemic in New Orleans, Louisiana, and fears that refugees could bring the disease into Arkansas; the Little Rock board was turned into the state board by Governor William Read Miller the following year. In 1881, the state legislature created an official state board of health, though it was inactive until 1897, when smallpox appeared in the state. Act 96 of 1913 created a permanent …

Arkansas Division of Information Systems (DIS)

The former Arkansas Department of Information Systems (ADIS) provided information technology solutions for the state government of Arkansas, maintaining the government’s telecommunication services and ensures connectivity and security among the various state agencies. The Transformation and Efficiencies Act of 2019 (Act 910) merged the Office of Transformation with the former ADIS to create the Department of Transformation and Shared Services as a cabinet-level department in state government, which includes the Division of Information Systems (DIS). The forerunner of ADIS was the Arkansas Department of Computer Services (ADCS), created by Act 884 of 1977, which abolished the Administrative Services Division of the Arkansas Department of Finance and Administration and transferred its duties and responsibilities to the newly created ADCS. The act …

Arkansas Entomological Society

The Arkansas Entomological Society (AES) was founded in May 1991 by entomology educators, researchers, and industry professionals under the guidance of Dr. William Yearian, former chair of the Entomology Department at the University of Arkansas (UA) in Fayetteville (Washington County). The first president of the society, Dr. Timothy Kring, drafted the society’s constitution with the purpose of fostering entomological accomplishment among its members as well as bringing about closer coordination and understanding among research, regulatory, educational, and commercial entomologists. Entomology is the study of insects and related organisms. Meetings of the society have been held annually since its founding, with locations and dates varying, but most often held on the first Friday and Saturday in October. Every other year, the …

Arkansas Fatmucket

aka: Lampsilis powellii

The Arkansas fatmucket is a bivalve mollusk belonging to the family Unionidae, commonly referred to as freshwater mussels, naiads, or clams. Each freshwater mussel is composed to two halves (valves) of a hard outer shell, with the living animal (soft tissues) residing securely inside. The Arkansas fatmucket (Lampsilis powellii) was described as a species new to science in 1852 by Isaac Lea, a naturalist and publisher by trade residing in Philadelphia, Pennsylvania. Lea based his description on specimens provided to him by Dr. Josiah Hale and Professor W. Byrd Powell from the Saline River at Benton (Saline County). Adults rarely reach a length of four inches (100 millimeters), and males and females are sexually dimorphic—that is, they have slightly different …

Arkansas Geological Survey (AGS)

The Arkansas Geological Survey (AGS), formerly the Arkansas Geological Commission (AGC), is a division of the Arkansas Department of Energy and Environment (ADEE) charged with the investigation of the geology, geologic processes, and geologic resources of the state. It is further charged to encourage the effective management and utilization of the various mineral, fossil-fuel, and water resources with proper consideration of the potential environmental impacts of that activity. The Geological Survey of Arkansas was first established in 1857 with engagement of David Dale Owen as state geologist. He was funded for three years and was only able to publish part of his findings. Owen ultimately published another report in 1860 just a few days before he died. His training in geology …

Arkansas Health Center

The Arkansas Health Center (AHC), located in Benton (Saline County), is a 310-bed nursing facility licensed and regulated by the Office of Long Term Care. AHC is the largest nursing home—and the only state-operated nursing facility—in Arkansas. With more than 550 employees, AHC provides nursing home care to Arkansans with special medical and behavioral needs that are not generally met through traditional nursing facilities. AHC houses specialty units to treat individuals diagnosed with Alzheimer’s disease or other forms of dementia, those with behavioral or psychiatric disorders, and those who are ventilator dependent for survival. AHC takes a holistic approach to healthcare, treating both the physical and psychiatric health concerns of the residents while also focusing on spiritual needs. Services available …

Arkansas Medical Society

The Arkansas Medical Society (AMS), founded in 1875, describes itself as the premier professional organization for Arkansas physicians. The AMS supports physicians and seeks to improve the delivery of healthcare services. In 1847, American allopathic physicians—that is, those within the regular medical mainstream—organized the American Medical Association (AMA) to promote medical educational and ethical standards. Established in the early 1840s, the Crawford County Medical Society was Arkansas’s earliest allopathic medical organization. Organized in 1870, the Arkansas State Medical Association (ASMA) was the first state organization for regular physicians. In 1873, a disagreement that divided the Little Rock and Pulaski County Medical Society members contributed to the ASMA’s eventual dissolution. At a meeting held in Little Rock (Pulaski County) in 1875, …

Arkansas Medical, Dental, and Pharmaceutical Association

The Arkansas Medical, Dental, and Pharmaceutical Association (AMDPA) was founded in 1893 by a group of African-American medical professionals. Barred from joining local white medical societies and the American Medical Association (AMA), black medical professionals organized their own local associations and national organization. Trained medical providers began moving into the Arkansas Territory around 1820. In the early 1880s, and in concert with trends in other states, several black physicians organized their own “Colored Medical Association.” These medical professionals were not only interested in the mutual recognition and fraternity offered by the organization; they were also genuinely concerned about the poor state of health among African Americans and the failure of white physicians to adequately address these healthcare needs. In 1893, …

Arkansas Methodist Medical Center

Arkansas Methodist Medical Center (AMMC) in Paragould (Greene County) provides healthcare for residents of northeast Arkansas and southeast Missouri. As of 2009, AMMC has more than eighty active and courtesy physicians from family practice to multiple specialties. A total staff of nearly 700 healthcare professionals works in a 400,000-square-foot facility. Salaries alone have an annual economic impact of more than $26 million. By the 1930s, Dickson Memorial Hospital in Paragould was past its prime. With combined support from citizens and the Paragould City Council, a donation of land by Joseph Bertig, and federal assistance from the Works Progress Administration (WPA), construction on a new hospital began in 1941. The new facility was seventy-five percent completed when the beginning of World …

Arkansas Mycological Society

The purpose of the Arkansas Mycological Society (AMS) is to educate its members in the differences between—and the similarities that occur within—edible, inedible, and poisonous mushrooms and other fungi that occur in Arkansas and to promote overall interest in Arkansas’s mushrooms and fungi. In the fall of 1980, Edith Nelson and Jay Justice, who had both recently joined the North American Mycological Society (NAMA), delivered a presentation on mushrooms and fungi at Pinnacle Mountain State Park. Edith Nelson (who died in 2004) was a retired high school teacher who had taught history and math, and Jay Justice was a chemist employed at what was at the time the Arkansas Department of Pollution Control and Ecology (now the Arkansas Department of …

Arkansas Native Plant Society

The Arkansas Native Plant Society (ANPS) was established in 1980 to promote, first, the preservation, conservation, study, and enjoyment of the native plants of Arkansas; second, the education of the public regarding the value of native plants and their habitats; and, third, the publication of related information. Regular meetings are held in the spring and fall of each year to conduct business, give presentations, and embark on field trips. The ANPS newsletter, Claytonia, is published preceding the spring and fall meetings. On November 17, 1979, consideration to form ANPS took place at the annual Arkansas Biological Curriculum Development Conference on the campus of the University of Central Arkansas (UCA) in Conway (Faulkner County). In a session discussing endangered plants, the …

Arkansas Nurses Association

On October 30, 1912, twenty-four Arkansas nurses gathered at the Young Women’s Christian Association (YWCA) in Little Rock (Pulaski County) to form the Arkansas State Graduate Nurse Association; in the twenty-first century, it is known as the Arkansas Nurses Association (ARNA). Then, as now, the association sought to promote professional standards for nursing education and practice through legislation, curriculum development, workplace policy recommendations, and general advocacy for the profession. Irene Howard Adylett led the organizational meeting attended by nurses from Little Rock, Fort Smith (Sebastian County), Pine Bluff (Jefferson County), Hot Springs (Garland County), Batesville (Independence County), Eureka Springs (Carroll County), and Fayetteville (Washington County).

Arkansas Research Alliance

A public/private economic-development organization, the nonprofit Arkansas Research Alliance (ARA) was established in 2008 with start-up funding from the State of Arkansas through the Arkansas Science and Technology Authority (ASTA). The organization evolved from the efforts of Accelerate Arkansas and its strategic plan of 2007. The ARA is modeled after the successful Georgia Research Alliance (GRA) that began under the leadership of Georgia governor Zell Miller in the early 1990s. The ARA’s primary focus is recruiting and retaining leadership in key research areas in which Arkansas has strong core competencies with long-term economic-development potential. The ARA has five university members: the University of Arkansas for Medical Sciences (UAMS) in Little Rock (Pulaski County), the University of Arkansas (UA) in Fayetteville …

Arkansas Research and Test Station

The Arkansas Research and Test Station site in Montgomery County near Hopper (Montgomery County) was one of two stations constructed in the United States in the early 1960s capable of transmitting communications to satellites orbiting the Earth. Constructed in 1965–66 and in operation until 1969, it was added to the National Register of Historic Places on September 21, 2017. The exact location of the site is restricted. The site was constructed by the Hughes Aircraft Company, founded by Howard Hughes. After initial efforts to place the site near Fayetteville (Washington County) to work with the University of Arkansas (UA) failed, the company struggled to find a suitable location. A location was finally chosen in rural Montgomery County that was located …

Arkansas Science and Technology Authority (ASTA)

The Arkansas Science and Technology Authority (ASTA) was created in 1983. Its mission is to bring the benefits of science and advanced technology to Arkansas. The legislation creating the authority was based on the growing interest in replicating the technology-based economies of Boston, Massachusetts; California’s Silicon Valley; and Research Triangle Park, North Carolina. For most states, the justification for establishing mechanisms similar to Arkansas’s was faith that investment in science and technology would lead to the creation of high-tech jobs. The first programs were implemented in 1986, and more have been added. The programs are grouped into three broad categories: research and commercialization, technology and manufacturing extension, and management services. In the research programs, ASTA provides funds and technical support …

Arkansas Sky Observatories

Arkansas Sky Observatories (ASO) is a network of four observatories that conduct studies of near Earth asteroids (NEOs), objects that pose a danger of impact at some point to planet Earth. ASO began in 1971, located on the south brow of Petit Jean Mountain. ASO was one of the first five contributing observatories to the Harvard-Smithsonian Center for Astrophysics network and continues to be a major contributor to the Harvard Minor Planet Center today. This relationship has resulted in more than 50,000 contributed orbital measurements of comets and asteroids. ASO was established by P. Clay Sherrod and his brother, Brian Sherrod. P. Clay Sherrod has authored seventeen books in astronomy, archaeology, and the environmental/biological sciences, and has patented numerous inventions …
