aka: Osmerids
Smelts belong to the family Osmeridae and order Salmoniformes. There are seven genera and about eleven species. Fishes of the genus Osmerus, to which the rainbow smelt (O. mordax) belongs, include the following: a North Pacific and Arctic species, O. dentex; the European smelt (O. eperlanus) of the Eastern North Atlantic; and the landlocked pygmy smelt (O. spectrum) of eastern Canada and New England, which some authorities suggest is not a valid species. In general, smelts are north circumpolar in geographic distribution, and they occur in marine and freshwater habitats in Asia, Europe, and North America. They date to the Paleocene Epoch (over 55 million years ago). The closest relatives are galaxioid (Protacanthopterygiid) fishes, and the marine argentinoid fishes are …
Morgan Smith—a physician, administrator, and legislator—was a leader in the drive to improve public health and medical education in Arkansas. Following his service as dean of the Arkansas Medical School, now the University of Arkansas for Medical Sciences (UAMS), from 1912 to 1927, he represented Pulaski County as a Democrat in the state House of Representatives from 1928 to 1934. Born on March 8, 1868, in El Dorado (Union County), Morgan Smith was the second son of James Monroe Smith, who was a planter and merchant, and Mary Josephine Morgan Smith. He had two brothers and one sister. His father, who formerly served in various county offices, was a state senator and a representative from Union County. Educated in the …
Dr. Willis S. Smith was a regionally significant teacher, sheriff, farmer, doctor, and writer in early southwestern Arkansas. Willis Smith was born on August 10, 1810, in Todd County, Kentucky, a frontier community. He was the fifth of twelve children of Millington Smith and Barbara Barton Smith. He was the grandson and namesake of Revolutionary War soldier Willis S. Smith, who was killed at the Battle of Bunker Hill. Smith had little opportunity for an education, and he could barely read or write even at twenty years of age. He left his home in Johnson County, Illinois, for Rock Springs Theological Seminary in Rock Springs, Illinois, where he received sufficient education to become a teacher at the school himself. One …
aka: Ophidiomycosis
Snake fungal disease (ophidiomycosis) is an emerging infectious disease of numerous species of snakes caused by the fungus Ophidiomyces ophiodiicola within the family Onygenacea. Formerly, Ophidiomyces was classified as the Chrysoporium anamorph of Nannizziopsis vriesii species complex (CANV species complex), a group of fungi that are frequently associated with emerging infections in various groups of reptiles. However, recent phylogenetic analyses have demonstrated that CANV represents a species complex that also includes fungi of the genera Nannizziopsis and Paranannizziopsis and that Ophidiomyces is known to occur only on both colubrid and viperid snakes. It was first definitively identified in 2006 in a population of timber rattlesnakes (Crotalus horridus) in New Hampshire. However, although identification has not been conclusively proven because cultures …
aka: Tornado Outbreak of April 10, 1929
The only F5 tornado ever recorded in Arkansas destroyed the Sneed and Pleasant Valley communities in Jackson County on April 10, 1929, one of a series of twisters on that day that claimed at least fifty-four lives in the state. At least eight tornadoes hit northeastern Arkansas on April 10, 1929. The most powerful, with wind speeds of 261 to 318 miles per hour, formed near Batesville (Independence County) and traveled northeast, entering Jackson County at about 6:15 p.m., with a half-mile-wide path. As it approached Pleasant Valley (also known as Possum Trot) north of Swifton (Jackson County), people sought shelter in homes that were quickly destroyed by the tornado “dipping down into the farm communities as if a gigantic …
William Anderson Snodgrass was an instructor at the University of Arkansas Medical School (which later became the University of Arkansas for Medical Sciences). During World War I, he organized Hospital Unit T and served as a major in the United States Medical Department in England and France. William Snodgrass was born on March 17, 1874, to Andrew J. Snodgrass and Elmira F. Masterfield Snodgrass at Murray, Kentucky. When he was ten, his family moved to Little Rock (Pulaski County). After completing public school and his premedical courses, he entered the Medical School of the University of Arkansas. He graduated in 1896 and was employed as Little Rock’s city physician in 1898. In 1898, he married Lelia Phillips, and they had …

The Society for the History of Medicine and the Health Professions was established as a support group for the Historical Research Center (HRC) of the University of Arkansas for Medical Sciences (UAMS) Library in Little Rock (Pulaski County). It supports research into the history of the health sciences in Arkansas. The society was founded in September 1981 by an executive committee composed of Dr. Robert Watson (the first neurosurgeon in Arkansas and a member of the UAMS College of Medicine faculty) as chair, Marie Smith (wife of Dr. John McCollough Smith), Dr. Horace Marvin (UAMS College of Medicine associate dean for academic affairs), Paul Harris (executive director of the Pulaski County Medical Society), and Edwina Walls (head of the HRC). …
Lidia Gertrudis Sogandares was the first Latin American woman to be accepted into the University of Arkansas School of Medicine (now the University of Arkansas for Medical Sciences—UAMS). A pioneer in medicine, she was the first woman to become a physician in Panama and one of the first female doctors in Central America. Sogandares became renowned in the medical fields of obstetrics and gynecology. Lidia Sogandares was born on October 17, 1908, on the island of Taboga in the Gulf of Panama. She grew up in a large family with four brothers and a younger sister. During her childhood, her father went to work for the National Navigation Company in Panama and later moved his family to Panama City. She …
A total solar eclipse is a phenomenon in which the moon totally obscures the bright light of the sun, leaving only the faint corona visible. Some residents of Arkansas Territory and some states in the South could see such an eclipse on November 30, 1834. The Arkansas Gazette announced the impending event in December 1833 by running an excerpt from the American Almanac stating that “the most remarkable of the phenomena that this year will happen, is the eclipse of the sun on Sunday, the 30th of November,” being total “in a small part of the territory of Arkansas” and in the states of Mississippi, Alabama, Georgia, and South Carolina. The article noted that “a great depression of the thermometer, …
The second of two recorded total solar eclipses—in which the moon totally obscures the sun, leaving only the corona visible—that could be seen in Arkansas occurred on June 8, 1918. While the first, in 1834, was clearly observed as a “magnificent phenomenon of nature in all its sublimity,” the 1918 event was reported as “somewhat of a disappointment.” On January 3, 1918, the Arkansas Gazette announced that June 8, 1918, would be “a gala day for astronomers,” as a total solar eclipse would cross the United States, beginning in northern Oregon and traveling to northern Florida “at a speed of something like 1,000 miles an hour.” The Hot Springs New Era noted a few weeks later that Mount Ida (Montgomery …
James Henry Southall was a founding member of the Medical Department of Arkansas Industrial University, the precursor to the University of Arkansas for Medical Sciences (UAMS). Southall was born on November 5, 1841, in Smithville, Virginia, the son and grandson of distinguished Virginia physicians. After the completion of his education and the interruptions of life caused by the Civil War, Southall moved to Little Rock (Pulaski County) at a time when the local medical community was beginning to consider forming a medical school in the state. As with many physicians of his era, Southall had begun his medical education by reading medicine under the tutelage of a professional, Dr. Robert Tunstall of Norfolk, Virginia. He attended medical school at the …
aka: Typhlichthys subterraneus
The southern cavefish (Typhlichthys subterraneus) is one of the two species of blind cave fishes found in Arkansas. The other is the Ozark cavefish. The southern cavefish is found in the subterranean waters of two major non-overlapping ranges separated by the Mississippi River: in the Ozark Plateau of central and southeastern Missouri and northeastern Arkansas and in the Cumberland and Interior Low plateaus of northwest Alabama, northwest Georgia, central Tennessee, and Kentucky. They are usually found at considerable depths (mostly between 175 and 240 meters below the land surface). This species, which can grow as long as ninety millimeters, has a large, broad head. The caudal fin has from zero to two rows of sensory papillae (one on the upper …
aka: Lampsilis streckeri
The speckled pocketbook 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 speckled pocketbook, scientific name Lampsilis streckeri, was described as a species new to science in 1927 by Lorraine Screven Frierson, a naturalist and landowner/merchant/planter residing south of Shreveport in the company town of Frierson, Louisiana. Frierson named the species in honor of his friend, colleague, and fellow naturalist John K. Strecker of Waco, Texas. Adults may reach a length of slightly more than 3.5 inches (or more than 90 millimeters), with a maximum life expectancy …
The phylum Porifera, which contains the sponges, is a highly successful group of metazoan animals that includes about 8,600 living species of marine and freshwater forms as well as some that inhabit brackish waters. The majority are marine, but there are about 150 species of freshwater sponges, including twenty-seven to thirty species found in North America north of Mexico. The family Spongillidae is the most speciose and widespread group of freshwater sponges and includes twenty-two genera and more than 130 species from a wide variety of habitats. Seven species of freshwater sponges have been documented in Arkansas. Sponges are an ancient group of asymmetrical invertebrates with a fossil record preceding the early Cambrian period (541 million years ago), and even …
aka: CHI St. Vincent Morrilton
With a view of the Arkansas River to the south and mountains to the southwest, the original building of St. Anthony’s Hospital in Morrilton (Conway County) (which later became CHI St. Vincent Morrilton) is an imposing three-story Art Deco–inspired structure made of brick and stone. It was added to the National Register of Historic Places on March 28, 1986. The Benedictine sisters at St. Scholastica Monastery established St. Anthony’s Hospital as a fourteen-bed facility on December 4, 1925, initially using a private home belonging to the Burrows family of Morrilton. During the following twelve years, they moved twice, first to a Harding College dormitory (when that school, now Harding University, was located in Morrilton), then to the Jones Hospital building …
St. Bernards Healthcare, based in Jonesboro (Craighead County), was founded by the Olivetan Benedictine sisters at Holy Angels Convent and is the largest employer in northeast Arkansas, with more than 2,200 employees. Its mission remains: “To provide Christ-like care to the community through education, treatment and health services.” Like many contemporary healthcare institutions, St. Bernards was begun in response to a crisis—a malaria fever epidemic that raged throughout northeast Arkansas in 1899. Civic leaders realized that the events of the 1890s had highlighted the need for a hospital, and as the twentieth century dawned, the idea was gaining momentum. A first challenge, and one that would be ongoing throughout the century, was to raise money necessary for a hospital. The …
aka: St. Joseph Center
St. Joseph’s Home sits on a summit overlooking North Little Rock (Pulaski County) and offers picturesque views of the Arkansas River and Pinnacle Mountain. Since 1910, the home has been a source of refuge for many Arkansans, children and elderly, as well as U.S. Army officers of World War I. It was placed on the National Register of Historic Places on May 4, 1976. Now called St. Joseph Center, it is home to a non-profit organization that offers urban farming opportunities. The Catholic Diocese of Little Rock, under the directive of Bishop John Baptist Morris, built St. Joseph’s Home. On July 1, 1907, Morris purchased a 720-acre farm, which at the time, was about four miles north of what is now …
aka: St. Joseph's Mercy Health Center
Founded as St. Joseph’s Infirmary, St. Vincent Hot Springs is the second-oldest hospital in Arkansas, serving the medical needs of Hot Springs (Garland County) and its surrounding communities since 1888. St. Vincent Hot Springs is a 282-bed, acute-care hospital located on Werner Street in Hot Springs. In the 1880s, the Reverend Patrick McGowan, who settled in Hot Springs after retiring, asked Hot Springs physician Dr. J. M. Keller to buy a suitable building and its surrounding property for a hospital. In 1888, Mother Aloysius Burke and Sister Mary Clare, two Sisters of Mercy, came to Hot Springs from Little Rock (Pulaski County) to prepare the thirty-bed hospital, St. Joseph’s Infirmary, for its grand opening. The hospital opened to Hot Spring residents …
aka: CHI St. Vincent
The Charity Hospital, founded in 1888, evolved into today’s St. Vincent Infirmary Medical Center of Little Rock (Pulaski County). The Charity Hospital was Arkansas’s first Catholic hospital, and St. Vincent remains the state’s oldest continuously operating hospital. What became known as CHI St. Vincent Health System, an affiliate of Catholic Health Initiatives, continues to emphasize the healing mission of the Catholic Church through its focus on the values of reverence, integrity, compassion, and excellence. The 1882 will of Alexander Hager, a wealthy Little Rock resident, promised to provide funding for hospital service in Little Rock if God spared the city from the yellow fever outbreak that was tearing through the South. When the outbreak passed over Little Rock, Hager’s will …
aka: Crataegus × Canescens
Stern’s medlar (Mespilus canescens or Crataegus × canescens) is a rare shrub in the rose family known in the wild from about twenty-five individual plants at a single site near Slovak (Prairie County). It was first discovered in 1969 by Jane Stern but was not named until 1990, when it was formally described (as Mespilus canescens) by Dr. James Phipps of the University of Western Ontario. Its origin, taxonomic placement, and proper scientific name are a matter of debate among botanists and represent one of the most curious and persistent mysteries in North American botany. Stern’s medlar is a showy species with a number of desirable ornamental properties including dense groupings of quarter-sized white flowers, multiple trunks, arching branches, patchy …
Robert Blair Stobaugh was an authority on energy, international business, and corporate governance who served as a professor in the Harvard Business School. His 1979 book Energy Future: The Report of the Energy Project led to significant initiatives in energy policy by the Carter administration and became a New York Times bestseller. His article “The Bent Measuring Stick of the Multinational Enterprise” was voted one of the twenty best articles ever published on international business. A federal judge once referred to him as “one of the nation’s foremost experts on corporate governance,” and was quoted on the front page of the Wall Street Journal several times. Robert Stobaugh was born on October 15, 1927, in McGehee (Desha County) to Robert …
Stoneflies (Phylum Arthropoda, Class Insecta, Order Plecoptera) are a group of aquatic insects well known to fishermen and biologists worldwide. The name Plecoptera means “braided-wings” from the Ancient Greek plekein and pteryx, which refers to “wing.” The name refers to the complex venation of their two pairs of wings, which are membranous and fold flat over their body. Generally, stoneflies are not strong fliers, and several species are entirely wingless. Stoneflies are called “indicator species” because finding them in freshwater environments generally indicates relatively good water quality, as they are quite intolerant of aquatic pollution. They are also prized and imitated by anglers as artificial tied-flies in trout fishing, particularly on Arkansas rivers such as the Eleven Point, Spring, and …
aka: Twisted Wing Parasites
The order Strepsiptera, or twisted wing parasites, belongs to the class Insecta, phylum Arthropoda. It is a very small, cosmopolitan order of bizarre parasitoids containing about 624 named species of minute endopterygote insects with nine extant families. They parasitize thirty-four families and several orders of Insecta, including Blattodea (cockroaches), Diptera (flies), Homoptera (leafhoppers), Mantodea (mantises), Hemiptera (true bugs), Orthoptera (grasshoppers and crickets), Zygentoma (silverfish and firebrats), and Hymenoptera (ants, bees, and wasps). Three species of strepsiptera (halictophagids) have been reported from Arkansas hosts (all leafhoppers, Cicadellidae). Strepsiptera have two major groups: the Stylopidia and Mengenillidia. The former, which has endoparasitic females with multiple genital openings, includes seven families: the Bohartillidae (one extant and two fossil species), Corioxenidae (forty-six extant and …
aka: Centruroides vittatus
The striped bark scorpion, Centruroides vittatus, is the only scorpion species recorded from Arkansas, where it is most abundant in the western part of the state. It is the most widely distributed scorpion species in the United States, having been recorded from Missouri, Arkansas, and Louisiana west to eastern Colorado and New Mexico and south to northeastern Mexico. The front body region, which bears the yellowish-brown pedipalps (pincers) and legs below, has a somewhat triangular median dark spot on top pointing backward and extending beyond the eyes. The wide body region that follows has a distinctive pair of broad, dark, longitudinal bands on top. The slender tail-like postabdomen is uniformly yellowish brown, except for the tip of the stinger, which …
Sturgeons (primitive Acipenseriform) are an ancient group of fishes dating back to the Triassic Period some 245 to 208 million years ago. True sturgeons appear in the fossil record during the Upper Cretaceous (101 to 66 million years ago). There are about twenty-five species of sturgeons, and all belong to the Family Acipenseridae, Order Acipenseriformes. Sturgeons can be found in subtropical, temperate, and sub-Arctic rivers, lakes, and coastlines of North America, with the greatest diversity in Eurasia. In North America, there are eight species that range along the Atlantic Coast from the Gulf of Mexico to Newfoundland, as well as along the West Coast in major rivers from California and Idaho to British Columbia, Canada. The family contains four genera …
aka: Catostomid Fishes
Suckers belong to the Family Catostomidae, Order Cypriniformes, and Class Actinopterygii. There are about seventy-two species and thirteen extant genera of these benthic (bottom-dwelling) freshwater fishes. In Arkansas, there are eighteen species in eight genera. Suckers are Holarctic in distribution and primarily native to North America north of Mexico, but the longnose sucker (Catostomus catostomus) occurs in both North America and northeastern Siberia from Alaska, and the Asiatic Sucker (Myxocyprinus asiaticus) is found in the Yangtze River basin in China. Sucker-like fossils are known from Eocene epoch (56 to 33.9 million years ago) deposits from central Asia, and the fossil genus Amyzon, with Ictiobus and Myxocyprinus affinities, occurs in middle Eocene and Oligocene Epoch (33.9 to 23 million years ago) …
Francis Cecil Sumner was the first African American to receive a PhD in psychology in the United States and has been acknowledged as the “father of black American psychologists.” His career featured pioneering work concerning equality and racial justice in education, and he furthered the development of future generations of black psychologists. Francis Cecil Sumner was born on December 7, 1895, in Pine Bluff (Jefferson County), one of two sons of David Alexander Sumner and Ellen Lillian Sumner. (While little is known about his parents, they are believed to have adopted the surname Sumner in honor of Massachusetts senator Charles Sumner, one of the Senate’s leading opponents of slavery and a major post–Civil War Radical Republican.) He received his elementary …
aka: Royal Circle of Friends
The Supreme Royal Circle of Friends of the World, also known as the Royal Circle of Friends (RCF), was an African-American fraternal organization founded in 1909 in Helena (Phillips County). The organization was founded to supply insurance to the African-American population but was also dedicated to the moral, physical, social, and economic welfare of its members. Men and women were equal members. From the beginning, the RCF grew rapidly across the Southern states and soon spread across the nation. In 1944, the membership was quoted by a Chicago, Illinois, newspaper as being in excess of 100,000. Dr. Richard A. Williams was the founding Supreme President and held that position until his death in 1944. Williams was born in Forrest City …
aka: Glasshouse Symphylans
Symphylans belong to the Phylum Arthropoda, Subphylum Labiata, Superclass Myriapoda, and Class Symphyla. About 200 species of symphylans are known worldwide, predominantly in the tropics. There are two families: Scutigerellidae with five genera and about 128 species, and Scolopendrellidae containing nine genera and approximately seventy-three species. There are few reports of symphylans in Arkansas, aside from a new endemic scutigerellid species described in 1992 in Polk County. Many taxa are yet to be discovered and described in the state. The fossil record of symphylans is poorly known; only five species have been recorded, all placed within living genera. They are ancestral arthropods dating back to the early Silurian approximately 430 million years ago, although the only fossil symphylans are known …
Tarantulas are the largest spiders in Arkansas and are among the most recognizable. Tarantulas are relative newcomers to Arkansas, having arrived in the state about 8,000 years ago. At that time, the climate of North America was much warmer and drier than it is today. Because of higher temperatures and lower amounts of rainfall, habitats more typical of the southwestern United States and the Great Plains expanded eastward into Arkansas and Missouri. Along with drier habitats came many of the animals associated with them, such as tarantulas and scorpions. As the climate became cooler and wetter about 4,000 years ago, these species did not retreat west. Instead, they became isolated within suitable patches of open, dry habitat surrounded by increasing …
aka: Water Bears
Tardigrades (sometimes called water bears or moss piglets) are microscopic members of the Phylum Tardigrada, numbering more than sixty-seven subspecies, 1,018 species, four subgenera, 105 genera, fifteen subfamilies, twenty families, five orders, and three classes. Of these, there are fifty-four genera and 380 species known from the Americas, 245 species from the Nearctic ecozone, and 251 in the Neotropical ecozone. Several species of tardigrades can be found in Arkansas. Discovered in 1773 by the German entomologist and pastor Johann August Ephraim Goeze (1731–1793), they were nicknamed “water bears” because of their plump, bear-like appearance; legs with claws; and slow, lumbering gait. The name Tardigrada (“slow steppers”) was given in 1777 by the Italian Catholic priest, biologist, and physiologist Lazzaro Spallanzani …
Emerging as a social problem in the United States during the late 1960s and early 1970s, teenage pregnancy has become a complex issue in the United States and around the globe. In the late 1980s and early 1990s, Arkansas’s state health director Dr. Joycelyn Elders, who later became U.S. surgeon general, made combating teenage pregnancy a major part of public health policy in Arkansas. Despite declines in rates since the 1990s, teen pregnancy remains an important public health issue in Arkansas and elsewhere. From the colonial era through the nineteenth century, the religious and legal concerns associated with teen pregnancy focused less on the parents’ ages and more on whether the parents were wed. Christianity condemned those, especially women, who …
aka: Moronids
The temperate basses are freshwater, brackish water, and marine species belonging to the Order Perciformes and Family Moronidae. They are represented by two genera and six species—the North American and northern African Morone (four species) and European Dicentrarchus (two species). In North America, two popular freshwater game fish species, white bass (Morone chrysops) and yellow bass (M. mississippiensis), are native, whereas two others, the anadromous striped bass (M. saxatilis) and brackish water white perch (M. americana), have been successfully introduced into several U.S. states. In Arkansas, M. chrysops, M. mississippiensis, M. saxatilis and, rarely, M. americana are found in various watersheds. In addition, hybrid M. saxatilis × M. chrysops have been cultured and stocked in several Arkansas reservoirs. Morphologically, in …
aka: Isopterans
Termites belong to the Phylum Arthropoda, Class Insecta, Infraorder Isoptera, and Order Blattodea. They were formerly placed in a separate order (Isoptera) from the cockroaches (Blattodea), but Isoptera is currently classified at the taxonomic rank of infraorder. About 3,106 species are currently described within twelve families, with a few hundred more to still be described. There are several species of termites in Arkansas. Termites are among the most successful groups of insects on Earth, colonizing all continents except Antarctica. Comparatively speaking, the diversity of termite species is rather low in North America and Europe (fifty species are known from North America, and only ten species occur in Europe), but it is higher in South America, where over 400 species are …
aka: Alexander Human Development Center
The Thomas C. McRae Memorial Sanatorium in Alexander (Pulaski and Saline counties) was established in 1931, in the midst of the Jim Crow era of racial segregation, to treat African-American victims of tuberculosis (often called “consumption” at the time). It was the first facility of its kind in Arkansas. It was opened twenty-two years after the Arkansas State Tuberculosis Sanatorium in Booneville (Logan County), which treated only white patients. In 1968, following the integration of the state’s sanatoriums, the Alexander site became the Alexander Human Development Center. In 2011, the facility was closed. The bill that created the McRae Sanatorium was introduced in the Arkansas General Assembly in 1923. It had strong support from the Arkansas Tuberculosis Association, particularly from …
Ruth Harris Thomas was a highly regarded amateur ornithologist whose column on birding in Arkansas was published by the Arkansas Gazette for about forty years. Her column not only documented area birds, but it also contributed to a growing appreciation for birds, birding, and habitat conservation. Ruth Harris was born in Kentucky on August 25, 1900, to Charles O. Harris and Columbia B. Cox Harris. She had two brothers. Majoring in English and journalism, Harris graduated from Louisiana State University in 1923, where she also edited the student newspaper. She moved to Little Rock (Pulaski County) in the autumn of 1923 to work as a reporter for the Arkansas Gazette newspaper. In 1927, she married Maine native Stanley Powers Rowland …
Thrips belong to the Phylum Arthropoda, Class Insecta, and Order Thysanoptera. They are minute (most are less than 1 mm long), slender insects with fringed wings and distinctive asymmetrical mouthparts. There are currently over 7,700 species-groups of recognized thrips, grouped into 780 extant and fifty-eight fossil genera. The traditional classification of the order recognizes nine families for extant species (plus five fossil families), with two subfamilies in the Phlaeothripidae (the only family in suborder Tubulifera) and four subfamilies in the Thripidae (one of eight families comprising suborder Terebrantia). The earliest recorded mention of thrips is from the seventeenth century and was a sketch made in 1691 by an Italian Jesuit scholar, Philippo Bonanni (1628‒1723). In 1744, the Swedish entomologist Baron …
Ticks are a very specific cosmopolitan collection of obligate, haematophagous, ectoparasitic arthropods of vertebrates (mostly on reptiles, birds, and mammals). They are important as vectors of bacterial (mainly rickettsial and spirochaetal), protistal, and viral disease agents of domestic animals and humans, as well as other mammals. By 2016, sixteen tickborne diseases of humans were known, which includes four emerging diseases discovered since 2013. In 2017, state and local health departments around the country reported a record number (totaling 59,349) of cases of tickborne diseases to the Centers of Disease Control and Prevention (CDC) in Atlanta, Georgia, up from 48,610 in 2016. Tickborne diseases can range from producing mild symptoms that are treatable at home to causing symptoms including fever and …
Ticks belong to the phylum Arthropoda, class Arachnida, subclass Acari, suborder Parasitiformes, and order Ixodida (Metastigmata), which includes almost 900 recognized species. There are three families: Ixodidae, or the “hard” ticks (approximately 700 species); Argasidae, or the “soft” ticks (approximately 200 species); and Nuttalliellidae, containing only a single species, Nuttalliella namaqua, a tick found only in southern Africa. In Arkansas, nine genera and a total of nineteen species (three argasids and sixteen ixodids) are known. Another species, Rhipicephalus (Boophilus) annulatus, has been extirpated from Arkansas. Ticks are a highly specialized group of obligate, bloodsucking, nonpermanent ectoparasitic arthropods of vertebrates (mostly on reptiles, birds, and mammals) and are distributed throughout the world. In addition to being irritating to hosts and causing …
After the establishment of the Master Settlement Agreement of 1998 between several major U.S. tobacco companies and four state governments (Texas, Florida, Minnesota, and Mississippi), the remaining forty-six states, the District of Columbia, and five U.S. territories not party to the original legal action were allowed to join into benefits conferred by the agreement. The tobacco companies were mandated to pay damages approaching the sum of $10 billion over an indefinite time period to the states joining the agreement, as well as acknowledge publicly that tobacco companies targeted youth in marketing and sales of products. In addition, the companies were subjected to sponsorship, marketing, and sales restrictions on their product. The State of Arkansas, agreeing not to file further litigation …
aka: Fundulids
Topminnows belong to the Family Fundulidae, Order Cypriniformes, and Class Actinopterygii. This family also includes some North American killifishes. There are approximately forty-four to forty-six species that are found in the lowlands of North and Central America from southeastern Canada to the Yucatan Peninsula of Mexico, including the Mississippi River drainage, and the islands of Bermuda and Cuba. Most (forty species) of topminnows belong to the genus Fundulus, and others are included in the genera Lucania (three species) and Leptolucania (a single species). The Family Fundulidae is a paraphyletic grouping of members of genera Fundulus and Lucania. There are six species of topminnows found in Arkansas. Topminnows occur in both freshwater and marine waters as well as brackish environments. They …
The tornado season of 1952 was a particularly eventful one throughout the state. Twenty-six tornadoes were reported to have touched down in Arkansas from January to November that year. While twenty-six is well below the modern average of about thirty-nine tornadoes per year in Arkansas, an unusually large number of these storms in 1952 were EF-3 and stronger on the Enhanced Fujita Scale used to rate the strength of tornadoes (the ratings go from EF-0 to EF-5). Of the twenty-six tornadoes in this outbreak, at least five were rated EF-4. Among these tornadoes, the most deadly and most widely reported was the March 21, 1952, EF-4 tornado that struck White County on March 21. Over the course of the year, …
On March 31, 2023, a massive outbreak of tornadoes struck nine states across the country, from Arkansas and Iowa to as far east as Delaware. The storms killed more than thirty people across seven states—five in Arkansas. One tornado hit the Pulaski County cities of Little Rock, North Little Rock, Sherwood, and Jacksonville. Another hit the eastern Arkansas community of Wynne (Cross County). This outbreak came a week after a similar system killed twenty-one people in Mississippi and one in Alabama. In the days leading up to the outbreak, the National Weather Service had been warning about the potential for severe storms striking the state on Friday, March 31, 2023. By the afternoon, a supercell started showing signs of becoming …
The tornado outbreak of March 1, 1997, was one of the deadliest in the history of the state of Arkansas. Sixteen tornadoes tracked across the state, killing twenty-five Arkansans. Several of the tornadoes had unusually long tracks, traveling between fifty and seventy-five miles. There was also a higher than statistically expected number of tornadoes of F3 strength or higher—that is, tornadoes with wind speeds in excess of 158 miles per hour. Of the sixteen tornadoes, four were responsible for all fatalities in the state, as well as much of the property damage. All sixteen tornadoes were produced by four supercell thunderstorms, with the four killer tornadoes being spawned from two such storms that formed ahead of a cold front. The …
Tornadoes—destructive, violently spinning vortices of air extending from high within severe thunderstorms to the surface of the earth—are more common in the United States than anywhere else on the planet. They are particularly prevalent in the area known as “Tornado Alley,” where the proper ingredients come together: a combination of warm, moist air from the Gulf of Mexico pulled northward by storm systems dragging strong continental cold air from Canada. While Arkansas is not normally included on maps of the infamous Tornado Alley, which is usually considered to stretch from north Texas northward through Oklahoma, Kansas, and Nebraska, the state has suffered many devastating tornado outbreaks. In January 1999, Arkansas recorded the most tornadoes on any individual January day in …
Eugene Jonas Towbin moved to Arkansas in 1955 to work at the Veterans Administration (VA) Hospital. He was a pioneer in the field of geriatric medicine, and his influence brought the first Geriatric Research Education and Clinical Center (GRECC) in the country to Arkansas. He was instrumental in obtaining funding for the John L. McClellan Memorial Veterans Hospital in Little Rock (Pulaski County) and was one of the founders of the geriatrics program at what is now the University of Arkansas for Medical Sciences (UAMS). He also supported cultural events and organizations in the Little Rock area. Eugene Towbin was born in New York City on September 18, 1918, to Russian Jewish immigrants Morris and Elena Towbin. He attended public …
When European explorers first came to Arkansas in the sixteenth century, they found the vast majority of the state covered by some type of forest or woodland. In general, the upland areas of the state were covered by short-leaf pine/oak/hickory forests in areas underlain by acidic rocks (primarily sandstone and chert) and by oak/hickory forests in areas underlain by neutral to calcareous rocks (primarily limestone and dolomite). Lowland areas of eastern and southern Arkansas were covered primarily by bottomland hardwood forests, with bald-cypress/water-tupelo swamps in the wettest areas. The Gulf Coastal Plain of southern Arkansas was covered by a mix of forest types, with loblolly and/or short-leaf pine dominant in many areas. Within these general forest types were hundreds of …
aka: Flatworms
Trematodes (flukes) include parasitic flatworms belonging to the phylum Platyhelminthes, class Trematoda, and subclasses Aspidogastrea (two orders, four families) and Digenea (ten orders, more than seventy-two families). The class numbers between 18,000 and 24,000 species; they are found primarily in a variety of animals, including humans and other vertebrates. Modern phylogenetic analysis reveals that the worms of class Monogenoidea (monogenetic flukes) are no longer included within the Trematoda and are more closely related to tapeworms. The modern mobility of human beings, combined with the international transportation of animals and foodstuffs that can be infected, means that diagnoses can occur well outside the areas where trematode species are endemic. However, while trematodes do occur in Arkansas, they do not pose a …
Opened in 1924, Trinity Hospital of Little Rock (Pulaski County) operated as a fee-for-service institution until 1931. That year, the physicians of Trinity implemented one of the early health maintenance organizations (HMOs)—a form of insurance in which member physicians provide medical care to voluntary subscribers for a fixed fee—in the United States. The former Trinity Hospital building was listed on the National Register of Historic Places on November 18, 1998. Trinity’s five founding physicians—Mahlon Dickerson Ogden Sr., Orange King Judd, Augustine Mathias Zell, James Isaac Scarborough, and Robert Booth Moore—began practicing medicine together before establishing the hospital. By 1916, Ogden, Judd, and Zell, who were also faculty members at the Arkansas Medical School—now the University of Arkansas for Medical Sciences …
