Seasonality Of Orthohantavirus Seroprevalence In Northwest Arkansas Rodents, Amy Schexnayder
Seasonality Of Orthohantavirus Seroprevalence In Northwest Arkansas Rodents, Amy Schexnayder
Biological Sciences Undergraduate Honors Theses
Zoonotic viruses are viruses that can be transmitted from animals to humans. Rodent species are likely to be reservoirs for zoonotic viruses, and particular rodent-borne viruses, such as orthohantaviruses, may greatly threaten human health. Orthohantaviruses are a group of rodent-borne viruses that are at risk for spillover to human populations. Many aspects of orthohantaviruses have been well-researched, yet the seasonality of orthohantaviruses has not yet been thoroughly examined, especially in the southern United States. In this study, we captured 616 rodents trapped over 5953 trap nights across 13 grassland sites in Northwest Arkansas. Rodents were trapped for two consecutive nights …
Distribution And Breeding Of The Black-Bellied Whistling-Duck (Dendrocygna Autumnalis) In Arkansas, With A Brief Chronology Of Distribution And Breeding In Southeastern United States, C. Renn Tumlison
Journal of the Arkansas Academy of Science
The Black-Bellied Whistling-Duck (Dendrocygna autumnalis) was a rare bird first reported from Arkansas in 1982, when it was seen in Hempstead Co. in southwestern Arkansas. Observations surged in parts of the state about 2005, then again about 2016, and the bird is now fairly common seasonally in many parts of the state. By use of online sources for citizen science, we elucidate the history of occurrence and present analysis of seasonal distribution of this bird in Arkansas. Individuals occur in Arkansas throughout the year, but observations are most common and widely distributed from March-September, after which most individuals …
A Study Of Dental Pathology In River Otters (Lontra Canadensis) In Arkansas, C. Renn Tumlison, Jimmie Harper, Karson Grant
A Study Of Dental Pathology In River Otters (Lontra Canadensis) In Arkansas, C. Renn Tumlison, Jimmie Harper, Karson Grant
Journal of the Arkansas Academy of Science
River otters (Lontra canadensis) consume a variety of foods, including mussels, fishes, and crayfishes. These foods have hard body parts that cause wear of the teeth as the predator ages and incurs more damaging feeding experiences. This can lead to exposure of the pulp cavity and possible abscess and resorption of bone around the alveolus. Further, strong bites against harder parts of prey sometimes results in mechanical breakage, which can lead to pulpitis and severe pathology leading to tooth loss. We investigated the frequency of different forms of dental issues in a sample of 178 skulls of river …
Eimeria Lancasterensis (Apicomplexa: Eimeriidae), Three Nematodes (Heligmosomoidea: Boehmiellidae, Heligmonellidae), And A Flea (Siphonaptera: Ceratophyllidae) From The Eastern Fox Squirrel, Sciurus Niger (Rodentia: Sciuridae) In Arkansas, Chris T. Mcallister, John A. Hnida, Henry W. Robison, Lance A, Durden, Christopher Whipps
Eimeria Lancasterensis (Apicomplexa: Eimeriidae), Three Nematodes (Heligmosomoidea: Boehmiellidae, Heligmonellidae), And A Flea (Siphonaptera: Ceratophyllidae) From The Eastern Fox Squirrel, Sciurus Niger (Rodentia: Sciuridae) In Arkansas, Chris T. Mcallister, John A. Hnida, Henry W. Robison, Lance A, Durden, Christopher Whipps
Journal of the Arkansas Academy of Science
In Arkansas, the eastern fox squirrel (Sciurus niger) is a common inhabitant of the state. Although information is available on ectoparasites of this host in Arkansas, little is known about the endoparasites of this squirrel. A single specimen from Montgomery County was examined and found to harbor the following: a coccidian (Eimeria lancasterensis), three nematodes, Boehmiella wilsoni, Citellinema bifurcatum, and Sciurodendrium hassalli, and a flea, Orchopeas howardi. We document these nematodes from an Arkansas S. niger for the first time, and add mensural and molecular information on E. lancasterensis from this host.

Selected Helminth Parasites (Cestoda, Nematoda) Of Bobcat, Lynx Rufus (Carnivora: Felidae), In Northeastern Arkansas, Chris T. Mcallister, Henry W. Robison, Ethan T. Woodyard, Thomas Graham Rosser
Journal of the Arkansas Academy of Science
The bobcat, Lynx rufus is a relatively common Arkansas carnivore that ranges statewide. Although there is a great deal of information on the natural history of this species in the state, there have been few studies where parasites have been documented in Arkansas bobcats. Here, a single specimen was examined and found to be infected with a tapeworm, Taenia rileyi and 2 nematodes, Toxoascaris leonina and Toxocara cati. We document the first record of T. rileyi from Arkansas and the first report of T. leonina from a bobcat in the state.
Novel Reproductive Data On Pealip Redhorse, Moxostoma Pisolabrum (Cypriniformes: Catostomidae), From Northeastern Arkansas, Chris T. Mcallister, Henry W. Robison, Ethan T. Woodyard, Thomas Graham Rosser, Thomas J. Fayton
Novel Reproductive Data On Pealip Redhorse, Moxostoma Pisolabrum (Cypriniformes: Catostomidae), From Northeastern Arkansas, Chris T. Mcallister, Henry W. Robison, Ethan T. Woodyard, Thomas Graham Rosser, Thomas J. Fayton
Journal of the Arkansas Academy of Science
Little is known about the natural history of the Pealip Redhorse (Moxostoma pisolabrum), particularly on its reproductive biology in Arkansas. We examined 11 female M. pisolabrum collected in late February 2020 and 2021 from the Black River, Lawrence County. Egg mass (g) represented 9‒14% of the total weight of these gravid females. This is the first time information on female reproduction in this species has been reported from any population of M. pisolabrum in the state.
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.
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
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 …

Parasites (Trematoda, Nematoda, Phthiraptera) Of Two Arkansas Raptors (Accipitriformes: Accipitridae; Strigiformes: Strigidae), Chris T. Mcallister, Lance A. Durden, Charles R. Bursey, John A. Hnida, Vasyl V. Tkach, Tyler J. Achatz
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.
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 …

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 …

Population Genetics, Distributions And Phenology Of Bombus Latreille, 1802 And Xylocopa Latreille, 1802 (Hymenoptera: Apidae), Amber Dawn Tripodi
Graduate Theses and Dissertations
This work addresses multiple knowledge gaps in bee ecology, population health and phylogeography in order to provide insights into the changing distributions of native bees. A comparison of Arkansas bumble bee records mirrors range-wide surveys, with records of stable species (Bombus bimaculatus Cresson, 1863 and B. impatiens Cresson, 1863) increasing three-fold, and records of the declining B. pensylvanicus (DeGeer, 1773) dropping to 60% of historical levels. However, nationally-recommended conservation-genetics tools did not mirror these results on a regional level. Stable and declining species had equivalent genetic diversity in samples from Arkansas and Tennessee (HS range: 0.46-0.63). Diploid males, …
Survival, Abundance, And Geographic Distribution Of Temperate-Nesting Canada Geese (Branta Canadensis) In Arkansas, Margaret Eliese Ronke
Survival, Abundance, And Geographic Distribution Of Temperate-Nesting Canada Geese (Branta Canadensis) In Arkansas, Margaret Eliese Ronke
Graduate Theses and Dissertations
Temperate-nesting Canada geese in Arkansas have grown in abundance and range since reintroduction in the 1980s. The Arkansas Game and Fish Commission uses harvest and other methods to maintain the population at desired levels. However, continued management of temperate-nesting geese requires knowledge of the population's demographics and current range to help establish quantifiable management goals.
To assess the need and effect of changing hunting regulations, survival and recovery rates and abundance were estimated for this population. Annual survival rates of temperate-nesting Canada geese banded and recovered in Arkansas from 2005 to 2011 were estimated using the Burnham joint live-dead recovery …
Behavioural Display Systems Across Nine Anolis Lizard Species: Sexual Dimorphisms In Structure And Function, Michele A. Johnson, J. Wade
Behavioural Display Systems Across Nine Anolis Lizard Species: Sexual Dimorphisms In Structure And Function, Michele A. Johnson, J. Wade
Biology Faculty Research
Relationships between structure and function are a primary focus in biology, yet they are most often considered within individual species. Sexually dimorphic communication behaviours and the morphology of associated structures can vary widely, even among closely related species, and these traits provide an ideal opportunity to investigate the evolution of structure-function patterns. Using nine Anolis lizard species, we addressed a series of questions regarding sex differences in and the evolution of relationships between extension of the throat fan (dewlap) and morphology of the muscles and cartilage controlling it. The main results indicated that within species, males displayed the dewlap more …
Diet Of Western Slimy Salamander, Plethodon Albagula (Caudata: Plethodontidae), From Two Mountain Ranges In Arkansas, Joseph Milanovich, Stanley E. Trauth, Tanja Mckay
Diet Of Western Slimy Salamander, Plethodon Albagula (Caudata: Plethodontidae), From Two Mountain Ranges In Arkansas, Joseph Milanovich, Stanley E. Trauth, Tanja Mckay
Biology: Faculty Publications and Other Works
We identified stomach contents of 80 Plethodon albagula (Western Slimy Salamander) from two mountain ranges in Arkansas (Ozark and Ouachita) to examine if regional differences in diet occur. Museum specimens from 1985 to 2005 were used from locations throughout each mountain range. Although a wide variety of prey were found in stomachs, Hymenoptera: Formicidae and Coleoptera: Carabidae were found to be the most important food items in the diet of P. albagula. Ants and beetles constituted 85% abundance of their total diet (79.6% Ozark and 90.1% Ouachita) and 52.2% of their total biomass (42.6% Ozark and 64.1% Ouachita). Seventy-eight and …
