Weather in the Civil War

Drought, flooding, bone-chilling winters, and intense summer heat all had an impact on the civilian and military populations of Arkansas during the Civil War, affecting military campaigns, access to food and supplies, and health conditions throughout the state. The Civil War was fought just after the end of a meteorological period that climate historians often call the Little Ice Age. This era, lasting roughly from 1300 to 1850, featured frequent climatic shifts, with bitterly cold winters switching to periods of heavy spring flooding, often followed by mild winters and subsequent droughts. While the trend toward cooling that characterized the Little Ice Age had moved toward warming by the 1860s, Civil War Arkansas would be plagued by temperature fluctuations that could …

Webspinners

aka: Footspinners
aka: Embiids
Webspinners or footspinners belong to the Phylum Arthropoda, Class Insecta, Subclass Pterygota, and Order Embioptera. They are a small group of mostly tropical and subtropical insects. More than 400 described species in eleven (eight extant) families are known, but it has been estimated that there might be around 2,000 extant species. Only three families (nine species) are present in North America: Anisembiidae (two species), Oligotomidae (three species), and Teratembiidae (four species). All of these occur in the southern United States, and most have fairly restricted ranges. At least two species occur in Arkansas, although very little is known about the embiopterans of the state. Embiopterans are found on every continent except Antarctica, with the highest density and diversity of species …

Welch, William Blackwell

In the late nineteenth century, physician William Blackwell Welch was a leader in the movement to modernize medicine in Arkansas. A cofounder and first president of the Arkansas Medical Society (AMS), he later led the effort to establish a city hospital in Fayetteville (Washington County). W. B. Welch was born on December 9, 1828, in Scottsville, Kentucky, to Christopher A. Welch, who was a farmer, and his wife, Elizabeth Lyles Welch. In 1829, his family, which eventually included two brothers and three sisters, moved to Somerville, Alabama. He attended schools in Huntsville, Alabama, and studied medicine under his older brother. After graduating from Tennessee’s University of Nashville medical department (later merged with the Vanderbilt University Medical School) in 1849, he …

West Nile Virus

West Nile virus (WNV) is an arthropod-borne, positive-sense, single-stranded RNA flavivirus (family Flaviviridae, genus Flavivirus) that has emerged as a significant health risk for humans. WNV is one of several Japanese encephalitis antigenic serocomplex of viruses that also include Japanese encephalitis virus, Murray Valley encephalitis virus, St. Louis encephalitis virus, and some other flaviviruses. West Nile has also been associated with illness and death in a wide variety of North American reptiles, birds, and mammals. It was first recognized in Arkansas in 2002. WNV was first identified in 1937 in the West Nile District of the Republic of Uganda of eastern Africa. Prior to 1995, the last major human outbreak of WNV was in the 1950s in Israel. The ecology …

Western Mosquitofish

aka: Gambusia
The western mosquitofish (Gambusia affinis) belongs to the order Cyprinodontiformes and family Poeciliidae. The name “mosquitofish” is appropriate for this fish because its diet sometimes consists of large numbers of mosquito larvae. The family contains about twenty-one genera and 160 species. There are eight other freshwater species of Gambusia similar in appearance in North America north of Mexico, including the eastern mosquitofish (G. holbrooki), Amistad gambusia (G. amistadensis), Big Bend gambusia (G. gaigei), largespring gambusia (G. geiseri), San Marcos gambusia (G. georgei), Clear Creek gambusia (G. heterochir), Pecos gambusia (G. nobilis), and blotched gambusia (G. senilis). Many of these Gambusia spp. are endemic and afforded protection, as populations are either listed as threatened or endangered. The similar western mosquitofish ranges …

White Nose Syndrome

White nose syndrome (WNS) is an emerging disease caused by an exotic fungus of the Phylum Ascomycota, Class Dothideomycetes, and Family Pseudeurotiaceae. This fungus is native to Europe and perhaps portions of Asia and is specifically termed Pseudogymnoascus destructans (Pd). Pd was unknown to science and undescribed until it was identified in 2008. Initially named Geomyces destructans, it was reclassified as P. destructans in 2013. The fungus was first found in Asia and Europe, where scientists believe it had existed for some time, as host bats do not appear to get as ill from the disease it causes. The strain of Pd that made it to North America is thought to have originated from some locality in Europe. There is …

Wildflowers

The varied ecosystems in Arkansas enable a large variety of wildflowers to grow within the state. From the river deltas to the mountaintops, Arkansas boasts an abundant array of over 600 native wildflowers. The majority of wildflowers in Arkansas are along rural roads and secluded areas. Due to the growing population and changes in the environment, the areas in which wildflowers grow are in constant fluctuation. Although highways and the development of land have eliminated a majority of the state’s native wildflowers, programs are under way to preserve these flowers and bring them back to the roadways. Common Wildflowers The most common wildflowers on Arkansas highways today are as follows: An in-depth list with descriptions of Arkansas wildflowers was written …

Williams, Robert Lee, II

Robert Lee Williams II was a leading figure in American psychology known for his work in the education of African-American children and in studying the cultural biases present in standard testing measures, especially IQ tests. He was inducted into the Arkansas Black Hall of Fame in 2011. Robert Lee Williams was born on February 20, 1930, in Little Rock (Pulaski County). His father, Robert L. Williams, worked as a millwright and died in 1935; his mother cleaned houses. He had one sister. He graduated from Dunbar High School at age sixteen and attended Dunbar Junior College for a year before dropping out, discouraged by his low score on an IQ test. He married Ava L. Kemp in 1948. They had …

Williams, Virginia Anne Rice

Biochemist Virginia Anne Rice Williams helped develop more nutritious grains through her pioneering studies of rice, a major Arkansas crop. She conducted important research on the B-vitamin content of rice, on ways to keep rice from turning rancid in storage, and on the vitamin fortification of rice. Virginia Rice was born in North Little Rock (Pulaski County) to Roderic J. Rice, a banker, and Mattie Thurman. Her high school teachers urged her to pursue music as a career, as she was a gifted musician. Fearing that she would not succeed as a concert musician, however, she opted for science, a field in which she also excelled. In 1940, Rice graduated from Hendrix College in Conway (Faulkner County) with a BA …

Willow Flycatchers

aka: Empidonax traillii
The willow flycatcher (Empidonax traillii) is the only bird species that has been discovered in the geographic area that is now the state of Arkansas. The noted naturalist and painter John James Audubon found the bird in 1822 while he was traveling near the community of Arkansas Post (Arkansas County), in what was then Arkansas Territory. When Audubon described the species in print for science in 1828, he named it Traill’s flycatcher for his friend Dr. Thomas Traill of Edinburgh, Scotland. Ornithologists have since determined that “Traill’s flycatcher” is really two different species, willow and alder flycatchers, which have almost identical appearances but distinctive vocalizations. The form Audubon discovered is of the species that was renamed willow flycatcher in 1973. …

Worms [Medical Condition], Traditional Remedies

aka: Intestinal Parasites
Well into the twentieth century, it was believed that all children had parasitic worms and that parents needed to treat this condition with patent or homemade medicines. These concoctions rid children of such intestinal parasites as roundworms (Ascariasis), threadworms (Trichuris), and tapeworms (Taenia solium), some of which also went by the colloquial names of pinworms and seatworms. Worm infestations, it was believed, could cause death. This is borne out by the census’s four mortality schedules (1850–1880). In these, “worms” and “worm fever” were listed as the causes of some children’s deaths, the majority occurring during the warm months of July through October. Some of these children may have died from the debilitating effects of worms or by being overdosed with …
