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 …

Arkansas State Crime Laboratory

The Arkansas State Crime Laboratory was established by Act 517 of 1977, Act 864 of 1979, and Act 45 of 1981. The laboratory offers services to state law enforcement agencies in forensic pathology, toxicology, physical evidence (serological and trace evidence), drug analysis, latent fingerprint identification, firearms and toolmarks, digital evidence, and DNA. The laboratory also participates with several federal agencies in the collection of data in the areas of DNA, through the Combined DNA Index System (CODIS); latent fingerprints, though the Integrated Automated Fingerprint Identification System (IAFIS); and firearms, through the National Integrated Ballistic Information Network (NIBIN). In 2019, the Arkansas State Crime Laboratory was placed under the newly created umbrella agency the Arkansas Department of Public Safety (ADPS), along …

Arkansas State Horticultural Society (ASHS)

The Arkansas State Horticultural Society (ASHS) is a horticultural crop producers’ organization whose primary purpose is to provide its members, through annual meetings, with information to enhance their horticultural enterprises. The Arkansas State Horticultural Society was formally organized on May 24, 1879, by nineteen men meeting in the council chamber of the city of Little Rock (Pulaski County). The organizers were engaged in horticultural pursuits and were aware of a growing interest in horticultural crops being grown on lands adjacent to the land-grant railroads then expanding through Arkansas. News of the May 24 meeting was published in area papers, extending an invitation for all interested to attend. The object of the society is “to collect and disseminate information relative to …

Arkansite

Arkansite—a mineral that exists in ten U.S. states and eleven countries—is actually brookite, the rarest of the three polymorphs (minerals containing the same chemistry but different internal structures) of titanium oxide. All three polymorphs—brookite, rutile, and anatase—are found at Magnet Cove (Hot Spring County). The brookite crystals found at Magnet Cove are sharp, black, and lustrous as opposed to the transparent or translucent brown/black crystals found elsewhere. This results from the substitution of varying amounts of iron and niobium for titanium in the structure. Charles Shepard (1804–1886) laid claim to the discovery of arkansite in a report he published in 1846. He named the “new” mineral arkansite after the state where the specimen he examined had been found. When a …

Asian Longhorned Tick

aka: Bush Tick
The Asian longhorned tick (Haemaphysalis longicornis) is an ectoparasite belonging to the Phylum Arthropoda, Class Arachnida, Order Acari, and Family Ixodidae. The Asian longhorned tick is native to temperate areas of eastern and central Asia, including China, Japan, and Korea, as well as various Pacific islands, including Australia, New Zealand, Fiji, New Caledonia, western Samoa, Vanuatu, and Tonga. In August 2017, a tick from an Icelandic sheep (Ovis aries) brought to the Hunterdon County Health Department in New Jersey was identified as H. longicornis. In November 2017, a large number of H. longicornis were discovered on a sheep farm, again in Hunterdon County. This tick had also been intercepted at U.S. port cities on imported animals and materials several times …

Aspidogastreans

aka: Aspidobothrians
aka: Aspidobothreans
An interesting group within the Class Trematodes (flukes) includes the Subclass Aspidogastrea. The Aspidogastrea is a very small taxon with around eighty species within thirteen genera, and their hosts include molluscs (sometimes spelled “mollusks”) and various vertebrates. They are of particular curiosity among parasitologists because of their unique structure, their simple life cycles (which may well be the most “primitive” ones among the trematodes), and the extraordinarily complex sensory/nervous systems found in some species.  There has been some debate among taxonomists about the relationships of the various genera of aspidogastreans; however, according to the prevalent view, there are four families as follows:  (1) Rugogastridae: with two caeca and single row of transverse rugae comprising a single genus Rugogaster; there are two species from the rectal glands of holocephalan ratfishes;  (2) Stichocotylidae: with one caecum and a single row of well separated suckerlets; includes a monotypic species (Stichocotyle nephropis) from …

Atherinopsids

aka: Neotropical Silversides
Atherinopsids, or neotropical silversides, belong to the order Atheriniformes and family Atherinopidae. There are about 104 species within thirteen genera found in euryhaline, marine, and freshwater habitats distributed throughout the tropical and temperate waters of the Western Hemisphere. Three well-known atherinopsid fishes are the Atlantic silverside (Menidia menidia), California grunion (Leuresthes tenuis), and Gulf grunion (L. sardina). There are three species in Arkansas: the brook silverside (Labidesthes sicculus), golden silverside (L. vanhyningi), and Mississippi silverside (Menidia audens). Prior to the Neogene Period of the late Tertiary Period (66 to 2.5 million years ago), there is no fossil record of atherinopsids in North America. However, on San Francisco Bay, important prehistoric intertidal fisheries were especially well documented for atherinopsids. Silversides are …

Audubon Arkansas

Audubon Arkansas was established in 2000 as the twenty-fifth state office of the National Audubon Society through a seed grant from the Winthrop Rockefeller Charitable Trust. Audubon Arkansas’s mission is to inspire and lead Arkansans in environmental education, resource management, habitat restoration, bird conservation, and enlightened advocacy. In 2003, Audubon Arkansas was recognized as “Conservation Organization of the Year” by the Arkansas Wildlife Federation. Robert Shults was the founding board chairman of Audubon Arkansas. Shults, an Arkansan, served on the National Audubon Society board of directors from 1980 to 1986. The chairman of the National Audubon Society at the time was Donal C. O’Brien. O’Brien and Shults both served on the board of trustees of the Winthrop Rockefeller Charitable Trust. …

Audubon, John James

John James Audubon, a frontier naturalist and artist, is famous for illustrating and writing The Birds of America. He visited Arkansas Territory in 1820 and 1822 and documented Arkansas’s birds, including the Traill’s flycatcher, also known as the willow flycatcher, which is the only bird originally discovered in Arkansas. John Audubon was born Jean Rabin on April 26, 1785, in Saint-Domingue (Haiti). He was the illegitimate child of Jean Audubon, a ship’s captain, and Jeanne Rabin, a French chambermaid. His mother died in 1785 or 1786, and Jean Audubon and his children returned to France after a slave revolt. Along with his sister, he was adopted by his father and stepmother in 1794. Audubon stayed with his father and stepmother …
