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 …
New Distributional Records For Ectoparasites (Acari: Laelapidae, Myocoptidae) Of The Woodland Vole, Microtus Pinetorum (Rodentia: Cricetidae) From Polk County, Arkansas, Chris T. Mcallister, Lance A, Durden
New Distributional Records For Ectoparasites (Acari: Laelapidae, Myocoptidae) Of The Woodland Vole, Microtus Pinetorum (Rodentia: Cricetidae) From Polk County, Arkansas, Chris T. Mcallister, Lance A, Durden
Journal of the Arkansas Academy of Science
The woodland vole, Microtus pinetorum is a common Arkansas rodent found statewide. To our knowledge, it has been surveyed only once in the state for ectoparasites. Here, a single specimen was examined and found to be infested with 3 species of mites, including Androlaelaps fahrenholzi, Laelaps alaskensis, and Myocoptes japonensis. This is the first time L. alaskensis and M. japonensis have been reported from Arkansas.
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
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.
Spatial And Temporal Variation In Aedes Albopictus Prevalence Across Arkansas, Alyssa N. Jones, Eric C. Lovely, Douglas G. Barron
Spatial And Temporal Variation In Aedes Albopictus Prevalence Across Arkansas, Alyssa N. Jones, Eric C. Lovely, Douglas G. Barron
Journal of the Arkansas Academy of Science
Aedes albopictus is a well-known vector species of mosquito that is responsible for the transmission of many arboviruses such as Zika, chikungunya, and dengue. The objective of this study was to quantify spatial and temporal variation of Ae. albopictus prevalence in Arkansas. We used egg abundance as a proxy for mosquito prevalence. Across 2 years, we worked with the Arkansas Department of Health to collect mosquito eggs using oviposition traps. Eggs were desiccated, counted, and later rehydrated in rearing chambers and raised through adulthood for species determination (>99% Ae. albopictus). We determined mean egg abundance by month, year, …
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.
Massard Prairie Restoration And Soil Microbiome Succession, Jeffrey M. Shaver, Emily S. Bellis, Chizuko Iwaki, Jake Qualls, Jay Randolph, Jeremiah Smith
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. …
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 …
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
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.
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 …
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
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.

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 …

Gene Flow And Genetic Structure Of Two Of Arkansas’S Rarest Darter Species (Teleostei: Percidae), The Arkansas Darter, Etheostoma Cragini, And The Least Darter, E. Microperca, Justin Baker, Brian Wagner, Robert Wood
Journal of the Arkansas Academy of Science
Distinguishing the effects of naturally caused historical fragmentation from those of contemporary landscape modification is critically important to understanding the consequences of human influences on patterns of gene flow and population dynamics. Nonetheless, relatively few recent studies focusing on this issue have dealt with species that showed evidence of historical fragmentation. In the current study, we disentangled the effects of fragmentation operating over separate timescales on two darter species, Etheostoma cragini and E. microperca, from the Ozark Highlands. Formerly more wide-spread within this region in Arkansas, these species now occur only in highly isolated habitats (i.e., spring-runs). …

Journal of the Arkansas Academy of Science
During October 2015, March and April 2016 and again between March and April 2017, 15 Spotted Sucker (Minytrema melanops) were collected from sites in the Ouachita (n = 5), Red (n = 1), and St. Francis (n = 5) river drainages, Arkansas, and the Arkansas River drainage, Oklahoma (n = 4), and examined for protozoan and metazoan parasites. Found were Calyptospora sp., Myxobolus sp., Pseudomurraytrema alabarrum, Biacetabulum banghami, Penarchigetes oklensis, and Acanthocephalus sp. New host and distributional records are documented for these parasites.

Because meaningful observations of natural history are not always part of larger studies, important pieces of information often are unreported. Small details, however, can fill gaps in understanding and lead to interesting questions about ecological relationships or environmental change. We have compiled recent important observations of distribution, deformities, and foods of various vertebrates, observations of winter activity of a woodchuck (Marmota monax) and winter torpor of a hoary bat (Lasiurus cinereus), and also report a very unusual case of bilateral gynandromorphism in a Cardinal (Cardinalis cardinalis). These unique observations continue to add immensely to …
