The Common Feeder Cockroach Blaptica Dubia Shows Increased Transmission Distance Based On Mode Of Acquisition Of Environmental Bacteria, Parker M. Campbell, Ryan J. Stork, Amber G. Hug
The Common Feeder Cockroach Blaptica Dubia Shows Increased Transmission Distance Based On Mode Of Acquisition Of Environmental Bacteria, Parker M. Campbell, Ryan J. Stork, Amber G. Hug
Journal of the Arkansas Academy of Science
Although some researchers claim that cockroaches are masters of disease transmission, these claims have little to no scientific support. Most studies concerning cockroaches as a vector of disease only focus on the bacteria found on the body surface, not on whether cockroaches have actually transferred pathogenic bacteria via surface contact. We set out to determine if cockroaches would act as a mechanical vector for the transfer of the opportunistic pathogen, E. coli. Roaches were contaminated with Green fluorescent protein expressing E. coli (GFP-E.coli) broth by either walking the roach through a broth culture or by complete immersion in the …

Massard Prairie Restoration And Soil Microbiome Succession, Jeffrey M. Shaver, Emily S. Bellis, Chizuko Iwaki, Jake Qualls, Jay Randolph, Jeremiah Smith
Journal of the Arkansas Academy of Science
We have initially sequenced soil microbial DNA from 4 restored and 4 virgin tallgrass prairie soil samples from Ben Geren Park and Massard Prairie (Fort Smith, AR), respectively. As expected, the soil microbiomes are distinct, with several lineages of nitrogen-fixing bacteria more common in virgin tall grass prairie. However, we predict that as restoration of tallgrass prairie in Ben Geren Park progresses, the soil microbiome of restored prairie will more closely mirror those of the virgin prairie.
Clinostomum Marginatum (Digenea: Clinostomidae) From Fishes Of Crooked Creek, Boone And Marion Counties, Arkansas, Chris T. Mcallister, Henry W. Robison
Clinostomum Marginatum (Digenea: Clinostomidae) From Fishes Of Crooked Creek, Boone And Marion Counties, Arkansas, Chris T. Mcallister, Henry W. Robison
Journal of the Arkansas Academy of Science
Crooked Creek is a renowned trophy (blue ribbon) Smallmouth Bass (Micropterus dolomieu) fishing stream. This fish, however, has been previously reported to commonly harbor some of the highest population densities of the digenean trematode parasite, Clinostomum marginatum, otherwise known as “yellow grub”. The parasite infects the orobranchial cavity, gills, and peritoneal cavity of Smallmouth Bass. Historical studies on this fish over the last 3 decades or more from various sites on the creek have shown that M. dolomieu also have high mean abundances but fish from upstream sites had lower prevalence than those collected from downstream sites. …

Journal of the Arkansas Academy of Science
Smaller details of natural history often go undocumented to science if those details are not parts 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 and reproduction of fishes and mammals. Included are new distributional records of mammals, and observations of reproduction in several mammals for which few data exist in Arkansas. A rare record of the Long-tailed weasel, a special of special concern in Arkansas, is documented from Newton Co. We also provide evidence that Seminole bats likely reproduce in …
Hemoparasites (Apicomplexa: Hepatozoon; Kinetoplastida: Trypanosoma) Of Green Frogs, Rana Clamitans (Anura: Ranidae) From Arkansas, Chris T. Mcallister, Ryan P. Shannon, Thomas J. Fayton, Henry W. Robison
Hemoparasites (Apicomplexa: Hepatozoon; Kinetoplastida: Trypanosoma) Of Green Frogs, Rana Clamitans (Anura: Ranidae) From Arkansas, Chris T. Mcallister, Ryan P. Shannon, Thomas J. Fayton, Henry W. Robison
Journal of the Arkansas Academy of Science
The green frog, Rana clamitans, has been reported as a host of several hemoparasites, including trypanosomes and Hepatozoon spp. In Arkansas, however, there are no reports of any hemoparasites in R. clamitans nor from any other anuran from the state. We collected 9 green frogs from Polk County and blood was taken from their facial musculocutaneous vein in heparinized capillary tubes. Thin blood smears were also made and stained with DipQuick stain. Seven out of 9 (78%) R. clamitans were infected with hematozoans. Three (33%) were infected with an unknown species of Hepatozoon and 4 (44%) were infected with …

Helminth Parasites Of Eastern Screech Owl, Megascops Asio (Aves: Strigiformes: Strigidae) From Arkansas, Chris T. Mcallister, Henry W. Robison
Helminth Parasites Of Eastern Screech Owl, Megascops Asio (Aves: Strigiformes: Strigidae) From Arkansas, Chris T. Mcallister, Henry W. Robison
Journal of the Arkansas Academy of Science
The eastern screech owl (Megascops asio) is a small owl that is relatively common in eastern North America. Nothing is known of the parasites of this owl in Arkansas. Here, we document 3 helminths from a single injured M. asio that subsequently died and was donated by a rehabilitation center for parasitic examination. Found were 2 digenetic trematodes, Brachylaima mcintoshi and Neodiplostomumamericanum, and a habronematid nematode, Excisa excisiformis. The former trematode represents a new host record for M. asio, and B. mcintoshi and E. excisiformis are reported from Arkansas for the first time.

Regional Variation In Ventral Body Color And Pattern In The Western Ratsnake, Pantherophis Obsoletus (Reptilia: Serpentes: Colubridae), In Arkansas, Stanley E. Trauth
Regional Variation In Ventral Body Color And Pattern In The Western Ratsnake, Pantherophis Obsoletus (Reptilia: Serpentes: Colubridae), In Arkansas, Stanley E. Trauth
Journal of the Arkansas Academy of Science
Pantherophis obsoletus, the Western Ratsnake (a.k.a., black ratsnake or chicken snake), is a large colubrid species widely distributed throughout the central and southcentral United States west of the Mississippi River (Powell et al. 2016). This species has received considerable attention with its early taxonomic history found in Neill (1949) and Dowling (1952) and its current phylogeographic status examined by Burbrink et al. (2000), Burbrink (2001), and Gibbs et al. (2006). Dorsal body color and pattern played an important role in resolving the early taxonomic issues within this ratsnake species complex, whereas mtDNA was utilized in the more recent phylogeographic analyses …
Distribution And Reproduction By The Purple Gallinule (Porphyrio Martinica) In Arkansas, C. Renn Tumlison, Terry L. Tumlison, Tamzen T. Bryant
Distribution And Reproduction By The Purple Gallinule (Porphyrio Martinica) In Arkansas, C. Renn Tumlison, Terry L. Tumlison, Tamzen T. Bryant
Journal of the Arkansas Academy of Science
The Purple Gallinule (Porphyrio martinica) is a rare bird in Arkansas, and its populations likely have declined due to loss of marshy areas with emergent vegetation. By use of online sources for citizen science combined with a field study, we elucidate the current distribution of this bird in Arkansas, and document characteristics of reproduction and development. Purple Gallinules arrive in Arkansas as early as April and remain to late October. Nesting occurs from early May into July, and nests may represent second broods. Ontogenetic changes in hatchlings are described.
Helminth Parasites Of The Golden Topminnow, Fundulus Chrysotus (Cyprinidontiformes: Fundulidae) From Desha County, Arkansas, Chris T. Mcallister, Thomas J. Fayton, Henry W. Robison, Stanley E. Trauth, Donald G. Cloutman
Helminth Parasites Of The Golden Topminnow, Fundulus Chrysotus (Cyprinidontiformes: Fundulidae) From Desha County, Arkansas, Chris T. Mcallister, Thomas J. Fayton, Henry W. Robison, Stanley E. Trauth, Donald G. Cloutman
Journal of the Arkansas Academy of Science
During July 2019, 21 Golden Topminnows (Fundulus chrysotus) were collected from an oxbow lake in McGehee, Desha County, Arkansas, and examined for parasites. Found were 4 taxa of endoparasites, including 3 digeneans (Clinostomum marginatum, Homalometron sp., and Posthodiplostomum minimum) and a nematode (Spiroxys contortus). We document a new host record for S. contortus and the first report of parasites in F. chrysotus from the lower Mississippi River Drainage.

Ecto- And Endoparasites Of The Texas Deermouse, Peromyscus Attwateri And Eastern Woodrat, Neotoma Floridana (Rodentia: Cricetidae) From Polk County, Arkansas, Chris T. Mcallister, Lance A, Durden, John A. Hnida, Henry W. Robison
Journal of the Arkansas Academy of Science
In Arkansas, the Texas deermouse (Peromyscus attwateri) occurs in the western part of the state where it is restricted to the uplands of the Interior Highlands. The eastern woodrat (Neotoma floridana) is found statewide but is less common in the Gulf Coastal Plain. Very little is known about the parasites of either rodent in Arkansas, especially helminths from P. attwateri at any locality within its range. Found in/on P. attwateri were a coccidian (Eimeria langbarteli), a tapeworm (Catenotaenia peromysci), a nematode (Syphacia peromysci), 2 ticks (Dermacenter variabilis and Ixodes …

Distal Urogenital Anatomy Of Male Prairie Racerunners, Aspidoscelis Sexlineatus Viridis (Reptilia: Sauria: Teiidae), Stanley E. Trauth
Distal Urogenital Anatomy Of Male Prairie Racerunners, Aspidoscelis Sexlineatus Viridis (Reptilia: Sauria: Teiidae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I examined histologically the distal urogenital anatomy in male Prairie Racerunners (Aspidoscelis sexlineatus viridis) from a small seasonal sample of individuals collected in Arkansas in order to provide additional information regarding squamate urogenital anatomy. Specifically, I focused on the basic anatomy and positioning of posterior ducts and associated structures in this teiid lizard. The anatomical structures included the ductus deferens, ampulla ductus deferens, ampulla urogenital papilla (Aup), ureter, inner core tissue mass, urodaeum, and the urogenital papilla. The two Aup, which are small complimentary blind pouches representing the terminal repositories for products released by urogenital ducts, are striking …
Energy Content Of Seeds Of Common Sunflowers (Helianthus Annuus) In The Diet Of Scaled Quail (Callipepla Squamata) In Southeastern New Mexico, John L. Hunt, Matthew E. Grilliot, Troy L. Best, Dixie Lozano-Lopez, Emily R. Neilson, Isaac C. Castillo

Journal of the Arkansas Academy of Science
We analyzed the energy content of seeds of common sunflowers (Helianthus annuus) obtained from the crops of scaled quail (Callipepla squamata) 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 common sunflowers from New Mexico was greater than that of many seeds previously reported from the diet of scaled quail and other granivorous …

Journal of the Arkansas Academy of Science
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.
