Very little is known about the helminth parasites of hawks and owls of Arkansas. We had the opportunity to salvage 2 road-killed raptors, a red-shouldered hawk (Buteo lineatus) and a great horned owl (Bubo virginianus) from the state and examine them for ecto- and endoparasites. Found were chewing lice (Degeeriella fulva) and a nematode (Porrocaecum angusticolle) on/in B. lineatus, and 3 digenean trematodes (Echinoparyphium sp., Strigea elegans, Neodiplostomum americanum), and nematode eggs (Capillaria sp.) in B. virginianus. We document 6 new distributional records for these parasites.
Age Estimation Using Phalangeal Skeletochronology In Northern Crawfish Frogs, Lithobates Areolatus Circulosus (Amphibia: Anura: Ranidae), From Arkansas, Stanley E. Trauth, Christopher S. Thigpen
Age Estimation Using Phalangeal Skeletochronology In Northern Crawfish Frogs, Lithobates Areolatus Circulosus (Amphibia: Anura: Ranidae), From Arkansas, Stanley E. Trauth, Christopher S. Thigpen
Journal of the Arkansas Academy of Science
As an obligate crayfish burrow dweller, crawfish frogs have historically occupied a relatively narrow ecological niche throughout their distribution in the tall grass prairies and grasslands of the central and south-central United States. In Arkansas, the Northern Crawfish Frog, Lithobates areolatus circulosus, occurs in only 19 of its 75 counties. Because of their secretive nature, late winter-early spring breeding season, and current protected status by the Arkansas Game and Fish Commission, this species remains a rarity in most museum collections in the state. Moreover, only anecdotal information exits regarding any aspect of their natural history in Arkansas. In the …
Plains Spotted Skunk Pelt Purchase Trends In The Ozarks And Ouachitas, 1943-1990, D. Blake Sasse
Plains Spotted Skunk Pelt Purchase Trends In The Ozarks And Ouachitas, 1943-1990, D. Blake Sasse
Journal of the Arkansas Academy of Science
The Plains spotted skunk (Spilogale putorius interrupta) is a small carnivore that has experienced population declines across much of its range and is currently being considered for listing as an endangered species. I utilized harvest data on pelts from the Ozarks of Missouri and Arkansas and the Ouachita mountains in Arkansas that were purchased by fur dealers from 1943-1990 to examine trends in harvest levels over time. Purchases in all three regions declined in the late 1940s and early 1950s, but purchases in the Arkansas returned to near or at historic levels in the early 1960s and the …
De Novo Development And Characterization Of Tetranucleotide Microsatellite Loci Markers From A Southeastern Population Of The House Finch (Haemorhous Mexicanus), Edgar E. Sanchez, J Dylan Maddox, Douglas G. Barron
De Novo Development And Characterization Of Tetranucleotide Microsatellite Loci Markers From A Southeastern Population Of The House Finch (Haemorhous Mexicanus), Edgar E. Sanchez, J Dylan Maddox, Douglas G. Barron
Journal of the Arkansas Academy of Science
Microsatellites are short tandem repeats (e.g. TAGATAGA) of base pairs in a species’ genome. High mutation rates in these regions produce variation in the number of repeats across individuals that can be utilized to study patterns of population- and landscape-level genetics and to determine parentage genetically. In this project our objective was to develop microsatellite markers for the House Finch, Haemorhous mexicanus. This species has become one of the most well-studied species of songbirds due to its unique geographical, evolutionary, and epidemiological history. Using mist-nets we captured birds on the Arkansas Tech University campus and collected blood samples to …
Occurrence Of The Sinus Nematode Skrjabingylus Sp. (Nematoda: Metastrongyloidea) Inferred From Sinus Lesions In Arkansas Mustelidae And Mephitidae, With Review Of Relevant Literature, C. Renn Tumlison, Terry Tumlison
Occurrence Of The Sinus Nematode Skrjabingylus Sp. (Nematoda: Metastrongyloidea) Inferred From Sinus Lesions In Arkansas Mustelidae And Mephitidae, With Review Of Relevant Literature, C. Renn Tumlison, Terry Tumlison
Journal of the Arkansas Academy of Science
Nasal nematodes of the genus Skrjabingylus occur in the mammalian families Mustelidae and Mephitidae, and have been found from Canada to Costa Rica. Ingestion of infected snails, frogs, snakes, or mice can lead to infection of these mammalian hosts. Infection often causes pathology to bones in the sinus region, which may lead to discoloration, enlargement, and fenestrations of the bone. Examination of museum specimens for bone lesions or other evidence of infection has been used to evidence prior infection, but prevalence and intensity cannot be interpreted without actually recovering the parasite. We examined Mustelids and Mephitids in collections of mammals …
Bilateral Diaphyseal Chondrodysplasia And Polymorphic Osteodysplasia Of The Tibiofibulas In A Southern Leopard Frog, Lithobates Sphenocephalus (Amphibia: Anura: Ranidae), Stanley E. Trauth, Malcolm L, Mccallum
Bilateral Diaphyseal Chondrodysplasia And Polymorphic Osteodysplasia Of The Tibiofibulas In A Southern Leopard Frog, Lithobates Sphenocephalus (Amphibia: Anura: Ranidae), Stanley E. Trauth, Malcolm L, Mccallum
Journal of the Arkansas Academy of Science
Much attention has been focused on limb malformations in anurans following the startling discovery of major limb deformities in Northern Leopard Frogs (Rana pipiens) in Minnesota in 1995. The numerous causes for these malformations can be attributed to a number of natural phenomena, or they can be considered as being manmade. In the present study, we report on a previously undescribed type of limb abnormality in a single individual of the Southern Leopard Frog (Lithobates sphenocephalus) from Arkansas. Histological examination of left tibiofibula revealed a complete disruption of the normal diaphyseal bone structure in this adult …

Proteomics Of Carbon Fixation Energy Sources In Halothiobacillus Neapolitanus, Jonathan Hunter, Maria Marasco, Ilerioluwa Sowande, Newton P. Hilliard Jr.
Proteomics Of Carbon Fixation Energy Sources In Halothiobacillus Neapolitanus, Jonathan Hunter, Maria Marasco, Ilerioluwa Sowande, Newton P. Hilliard Jr.
Journal of the Arkansas Academy of Science
Through the use of proteomics, it was uncovered that the autotrophic, aerobic purple sulfur bacterium Halothiobacillus neapolitanus displays changes in cellular levels of portions of its carbon dioxide uptake and fixation mechanisms upon switch from bicarbonate to CO2(g) as carbon source. This includes an increase in level of a heterodimeric bicarbonate transporter along with a potential switch between form I and form II of RubisCO. Additional changes are seen in several sulfur oxidation pathways, which may indicate a link between sulfur oxidation pathways as an energy source and carbon uptake/fixation mechanisms.
Distribution, Habitat, And Life History Aspects Of The Dwarf Crayfishes Of The Genus Cambarellus (Decapoda: Cambaridae) In Arkansas, Henry W. Robison, Chris T. Mcallister
Distribution, Habitat, And Life History Aspects Of The Dwarf Crayfishes Of The Genus Cambarellus (Decapoda: Cambaridae) In Arkansas, Henry W. Robison, Chris T. Mcallister
Journal of the Arkansas Academy of Science
The dwarf crayfishes of the genus Cambarellus are represented in Arkansas by only 2 species: Cambarellus (Pandicambarus) puer (Hobbs) and C. (P.) shufeldtii (Faxon). Both species are quite small and uncommonly encountered in the state. Between 1972 and 2018, we made 368 crayfish collections throughout the 75 counties of Arkansas. A total of 34 collections (our collections, plus museum specimens), and those previously collected by Reimer (1963) yielded a total of 304 specimens of C. puer and 12 collections of C. shufeldtii returned 54 specimens of C. shufeldtiii. Herein, we document these …
The Reproductive Season Of The Highland Stoneroller, Campostoma Spadiceum, Evidenced By Museum Specimens, C. Renn Tumlison, Henry Robison, Grace Wills
The Reproductive Season Of The Highland Stoneroller, Campostoma Spadiceum, Evidenced By Museum Specimens, C. Renn Tumlison, Henry Robison, Grace Wills
Journal of the Arkansas Academy of Science
The Highland Stoneroller (Campostoma spadiceum) was described as a distinct species in 2010. Since then, the only study specific to this species is a survey of distribution, and nothing is known about reproduction. We examined 134 lots including 315 specimens of C. spadiceum housed in the Henderson State University collection of fishes to evaluate the timing of reproductive events. We dissected individuals to reveal sex and reproductive status. Females as small as 49 mm total length were able to yolk eggs, and follicles were in development by October. Ripe eggs were present in specimens collected from January through …
Vertebrate Natural History Notes From Arkansas, 2019, C. Renn Tumlison, Chris Mcallister, Henry Robison, Matt Connior, Ron Redman, Stan Trauth, Paul Port
Vertebrate Natural History Notes From Arkansas, 2019, C. Renn Tumlison, Chris Mcallister, Henry Robison, Matt Connior, Ron Redman, Stan Trauth, Paul Port
Journal of the Arkansas Academy of Science
Important observations of natural history often go unreported because they are not part of larger studies, but small details can provide insights that lead to interesting questions about ecological relationships or environmental change. We have compiled recent important observations of distribution, deformities, foods, parasites, and reproduction of various vertebrates. Included are a new record of Lake Sturgeon (Acipenser fulvescens), a new size record of mudpuppy (Necturus louisianensis), and a second observation of bilateral gynandromorphism in a Northern Cardinal (Cardinalis cardinalis). These unique observations continue to grow knowledge of vertebrate biology in Arkansas.

Notes On The Natural History Of Selected Invertebrates From Arkansas, 2019, Matthew B. Connior, Renn Tumlison, Henry Robison
Journal of the Arkansas Academy of Science
The invertebrate fauna are a large component of ecosystem. Yet, invertebrate biologists are few and scattered in Arkansas; thus, the invertebrate fauna of much of the state is poorly known. Herein we document new records of distribution and provide notes on the natural history of selected invertebrates from Arkansas. Of note, we provide records on planarians, crayfish, centipedes, and spiders.

Observations Of An Alligator (Alligator Mississippiensis) Nest And Behavior Of Hatchlings In Clark County, With Anecdotal Observations Of Other Alligator Nests In Arkansas, Allison Surf, Kevin Nordengren, C. Renn Tumlison, Kelly Irwin
Journal of the Arkansas Academy of Science
Historically, the American alligator (Alligator mississippiensis) ranged through southern and much of eastern Arkansas. By the early 1900s, alligator populations had declined due to unregulated hunting, commercial exploitation, and habitat loss. In 1961, the Arkansas Game and Fish Commission (AGFC) established protection of this species, and in 1967 the U.S. Fish and Wildlife Service listed the alligator as an endangered species. The AGFC conducted a restocking program from 1972-1984, and the species made a full recovery in Arkansas. Still, little is known about reproductive biology in the state. We observed an alligator nest near Arkadelphia, Clark Co., the mound …

Adams
Journal of the Arkansas Academy of Science
Agricultural land use is known to degrade aquatic systems with high inputs of nutrients, sediments, and pesticides. Increased nutrients can lead to increased algal growth and thus possible hypoxic conditions in slow moving water, while increased sediment loads have been shown to obstruct light and reduce substrate stability. These conditions negatively impact primary producers, macroinvertebrates, and fish. However, small-scale changes in land use can subsidize an aquatic ecosystem instead, where an increase in nutrients allows nutrient-limited biota to flourish, and minor increases in sedimentation may help support populations of collector-filterers. The stimulation in performance caused by small disturbances is part …

Energy Content Of Seeds Of Texas Doveweed (Croton Texensis) From The Diet Of Mourning Doves (Zenaida Macroura) From Southeastern New Mexico, John L. Hunt, Matthew E. Grilliot, Troy L. Best, Collin S. Deen, Dixie Lozano-Lopez, Emily R. Neilson, Taytumn R. Schlegel-Ridgway
Journal of the Arkansas Academy of Science
We analyzed the energy content of seeds of Texas doveweed (Croton texensis) obtained from the crops of mourning doves (Zenaida macroura) collected from plains-mesa sand-scrub habitat in Eddy and Lea counties, New Mexico. Seeds were removed from crops and dried for 48 hours at 60°C to remove moisture and to standardize masses. Seeds were then analyzed for gross caloric value (i.e., energy content) in an oxygen bomb calorimeter. Energy content of seeds of Texas doveweed was greater than many seeds previously reported from the diet of mourning doves.
Long-Tailed Weasel (Mustela Frenata) Distribution Survey In Arkansas: Challenges In Detecting A Rare Species, Suzanne D. Johnston, D. Blake Sasse, Robert E. Kissell Jr.
Long-Tailed Weasel (Mustela Frenata) Distribution Survey In Arkansas: Challenges In Detecting A Rare Species, Suzanne D. Johnston, D. Blake Sasse, Robert E. Kissell Jr.
Journal of the Arkansas Academy of Science
Long-tailed weasels (Mustela frenata) have one of the widest distributions of mustelids in the western hemisphere and were distributed across a majority of the American continents ranging from Canada through the contiguous United States, Mexico, and into northern South America. However, on a local scale they are considered uncommon and rare. We assessed the distribution of long-tailed weasels across Arkansas to determine occupancy in each ecoregion of Arkansas, and determined the detectability on two local, adjacent sites. No long-tailed weasels were detected within the ecoregions, but the species was detected with intensive sampling on one local site. It …
The Impact Of Prescribed Fire On Moth Assemblages In The Boston Mountains And Ozark Highlands, In Arkansas, Erin E. Guerra, Cristina M. Blanco, Jorista Garrie
The Impact Of Prescribed Fire On Moth Assemblages In The Boston Mountains And Ozark Highlands, In Arkansas, Erin E. Guerra, Cristina M. Blanco, Jorista Garrie
Journal of the Arkansas Academy of Science
In addition to the impacts of prescribed fires on forest vegetation, this ecosystem process also has dramatic impacts on associated insect assemblages. For herbivorous, terrestrial insects, fire predictably results in a cycle of initial insect population reduction followed by recovery and growth, in which these insect populations exceed pre-fire abundances. We sought to examine if fire-induced disturbance cycles make prescribed burned areas more or less suitable specifically for moths (order Lepidoptera), which is a major food source for, among others, multiple bat species. We surveyed moth assemblages at 20 burned and 20 unburned sites in the Boston Mountain and Ozark …
History And Current Status Of The Inca Dove (Columbina Inca) In Arkansas, Ragupathy Kannan, Jack Jackson, Ethan Brooks
History And Current Status Of The Inca Dove (Columbina Inca) In Arkansas, Ragupathy Kannan, Jack Jackson, Ethan Brooks
Journal of the Arkansas Academy of Science
Formerly a bird of Central America, Mexico, and the southwestern United States, the Inca Dove (Columbina inca) has been expanding northward across North America in the past few decades. It first appeared in Arkansas on October 26, 1968 in Saratoga, Howard County. Since then, the statewide range has grown to include at least 36 of 75 counties and is expanding. With the use of Christmas Bird Counts, Breeding Bird Surveys, and two citizen science sources, eBird and AR-Birds, we compiled 368 records of the species in the state. Inca Doves were observed year-round in Arkansas and are expanding …
