Acanthocephala Of Arkansas, Including New Host And Geographic Distribution Records From Fishes, C. T. Mcallister, D. J. Richardson, M. A. Barger, T. J. Fayton, H. W. Robison
Journal of the Arkansas Academy of Science
Little is known about the spiny- or thorny-headed worms (Phylum Acanthocephala) of Arkansas and there are no summaries on the acanthocephalans of the state. Here, we provide a checklist of the 22 acanthocephalans that occur in Arkansas’ vertebrates based on previously published records and new data presented herein. In addition, we document a new state record as well as 13 new host records for some fish acanthocephalans.
Food Habits Of Green Tree Frogs (Hyla Cinerea) From Arkansas, C. S. Thigpen, H. Dodson, S. E. Trauth
Food Habits Of Green Tree Frogs (Hyla Cinerea) From Arkansas, C. S. Thigpen, H. Dodson, S. E. Trauth
Journal of the Arkansas Academy of Science
We analyzed stomach contents of 120 Green Tree Frogs, Hyla cinerea, collected between May 1956 and October 2014 in Arkansas. Beetles and arachnids were the predominant prey item; the next most abundant groups were Diptera and Hemiptera. Vegetable matter was also found in several frogs. All identifiable vegetable matter was determined to be of the genus Persicaria, colloquially known as smartweed. Our data suggests that Green Tree Frogs in Arkansas predominantly feed on beetles and arachnids, but occasionally ingest plant matter when actively foraging.
Hematozoan Parasites (Apicomplexa, Kinetoplastida) Of Seven Arkansas Reptiles (Testudines, Ophidia), C. T. Mcallister, M. B. Connior, H. W. Robison, T. J. Fayton, R. Tumlison, S. E. Trauth

Journal of the Arkansas Academy of Science
Little is known concerning the hematozoan parasites of Arkansas reptiles. Although there are previous reports in the state of these intraerythrocytic parasites infecting various reptiles, additional research is sorely needed. Here, we attempt to augment that void by providing additional hosts infected by these apicomplexans, including the first report of a trypomastigote of a Trypanosoma sp. from an Arkansas turtle.
New Distributional Records Of The Ohio Shrimp, Macrobrachium Ohione Smith (Decapoda: Palaemonidae) In Arkansas, H. W. Robison, L. Lewis, C. Cox, G. Spooner, R. Adams, C. T. Mcallister
New Distributional Records Of The Ohio Shrimp, Macrobrachium Ohione Smith (Decapoda: Palaemonidae) In Arkansas, H. W. Robison, L. Lewis, C. Cox, G. Spooner, R. Adams, C. T. Mcallister
Journal of the Arkansas Academy of Science
The Ohio shrimp (Macrobrachium ohione) is a migratory (amphidromous) river shrimp that occurs in some Arkansas rivers. It is known from the Upper Missouri River from its mouth downstream to the Gulf of Mexico, but shrimp abundance has declined, particularly upstream of Louisiana. Ohio Shrimp has also been collected in the lower reach of the Missouri River not far from the confluence of the Mississippi River in St. Louis County. Dams and alterations in channel flow are hypothesized to have impacted upriver migrations of shrimp. Current range, abundance, and life history of Ohio shrimp is relatively unknown in the Mississippi …
Water-Quality Effects On Phytoplankton Species And Density And Trophic State Indices At Big Base And Little Base Lakes, Little Rock Air Force Base, Arkansas, June Through August, 2015, L. J. Driver, B. G. Justus
Water-Quality Effects On Phytoplankton Species And Density And Trophic State Indices At Big Base And Little Base Lakes, Little Rock Air Force Base, Arkansas, June Through August, 2015, L. J. Driver, B. G. Justus
Journal of the Arkansas Academy of Science
Big Base and Little Base Lakes are located on Little Rock Air Force Base, Arkansas, and their close proximity to a dense residential population and an active military/aircraft installation make the lakes vulnerable to water-quality degradation. The U.S. Geological Survey (USGS) conducted a study from June through August 2015 to investigate the effects of water quality on phytoplankton species and density and trophic state in Big Base and Little Base Lakes, with particular regard to nutrient concentrations. Nutrient concentrations, trophic-state indices, and the large part of the phytoplankton biovolume composed of cyanobacteria, indicate eutrophic conditions were prevalent for Big Base …
Impact Of Climate Variations On Soybean Yield In Eastern Arkansas: 1960-2014, J. W. Magugu, S. Feng, Q. Huang, K. Luthra
Impact Of Climate Variations On Soybean Yield In Eastern Arkansas: 1960-2014, J. W. Magugu, S. Feng, Q. Huang, K. Luthra
Journal of the Arkansas Academy of Science
Climate is the major factor affecting crop production; therefore, various agro-meteorological indicators have been frequently used to evaluate the impact of climate on crop production. In this study, we examined the temporal variations of agrometeorological indicators (growing degree days, total precipitation, dry spells and drought indices) during 1960-2014 and their impact on soybean yields in East Arkansas. Results show an increasing trend in growing degree days (GDDs) and dry spells, though the total precipitation during the soybean growing season remained nearly unchanged during the study period. Generally, GDDs and dry spells show a strong correlation with yields. We also evaluated …

Population Sampling Of Chelonians In An Urban Lake In Jonesboro, Craighead County, Arkansas, J. D. Konvalina, C. S. Thigpen, S. E. Trauth
Journal of the Arkansas Academy of Science
We conducted a mark-recapture survey for aquatic turtles in Craighead Forest Lake in Jonesboro (Craighead County, Arkansas). From July 2, 2015 to October 14, 2015, we set six hoop nets, baited with fish parts, at specific shoreline locations around the lake. Traps were set twice a week and checked 12 hours after they were set. Carapace length, carapace width, plastron length, and plastron width were measured for each individual. Each turtle was identified to species and its sex was recorded. We also placed a notch in one or more of its marginal scutes to aid in future identification. Finally, a …

Vegetation Diversity In Natural And Restored Forested Wetland Sites In Southeast Arkansas, C. J. Sheldon, R. L. Ficklin, K. P. Fawley, M. W. Fawley, M. Bataineh, A. S. Nelson, S. Wilson
Journal of the Arkansas Academy of Science
The loss of forested wetlands in the Lower Mississippi River Alluvial Valley in Arkansas has altered regional vegetation communities. Multiple restoration projects have been established in this region to restore wetlands and the services they provide. In order to return these functions to the environment, microtopographic features were constructed in 2001 at Bob White Memorial Wetlands Research and Teaching Station (Bob White). Vegetation diversity was examined at Cut-Off Creek Wildlife Management Area (Cutoff), a naturally forested wetland, and Bob White, an area formally converted to cropland that is now undergoing forest wetland restoration. Vegetation diversity is one way to determine …
History And Fall Migration Of Northern Saw-Whet Owls (Aegolius Acadicus) In Arkansas, M. L. Pruitt, K. G. Smith
History And Fall Migration Of Northern Saw-Whet Owls (Aegolius Acadicus) In Arkansas, M. L. Pruitt, K. G. Smith
Journal of the Arkansas Academy of Science
The secretive Northern Saw-whet Owl (Aegolius acadicus) is believed to be much more widespread during fall and winter than previously thought in the southern United States. To see if they occur more frequently in Arkansas, we initiated a banding study in fall of 2014 in northwestern Arkansas. Prior to that, only 12 historic records existed for Arkansas between 1959 and 2010. Over the course of two field seasons, we captured and banded 24 Northern Saw-whet Owls in rural Madison County. All birds were mist-netted along a trail, in woodland composed of pine and cedar with fairly dense undergrowth. Two were …
The Ticks (Arachnida: Acari: Ixodida) Of Arkansas, C. T. Mcallister, L. A. Durden, H. W. Robison
The Ticks (Arachnida: Acari: Ixodida) Of Arkansas, C. T. Mcallister, L. A. Durden, H. W. Robison
Journal of the Arkansas Academy of Science
Although ticks are a nuisance to humans and other animals, they are an important part of the biota of North America. In addition, they are vectors of many tick-borne disease agents that can negatively affect higher vertebrates. In Arkansas, there have been no recent comprehensive summaries of the ticks (Acari: Ixodida) in the last 40+ yrs. Here, we provide a summary of the ticks of the state and note the disease agents they can transmit.

L. Mccallum, D. H. Jamieson, A. Holt, J. B. Trauth, H. Hicks, J. W. Stanley, J. Elston, J. J. Kelly, J. D. Konvalina
Journal of the Arkansas Academy of Science
We conducted a mark-recapture study of Alligator Snapping Turtles, Macrochelys temminckii, on Salado Creek (Independence Co., Arkansas) during 10 trapping seasons, which spanned a 20-year period (1995–2015). We trapped a total of 163 Alligator Snapping Turtles during 416 trap nights and recorded a total of 35 recaptures during this study. Both the catch per unit effort (CPUE) and Jolly-Seber approaches demonstrated that this population benefitted from removal of harvest pressure, thus leading to an increase in abundance of Alligator Snapping Turtles in the lower ~5 km of the creek. The CPUE averaged slightly greater than 0.24 (317 trap nights) during …

Vertebrate Natural History Notes From Arkansas, 2016, R. Tumlison, C. T. Mcallister, H. W. Robison, M. B. Connior, D. B. Sasse, D. A. Saugey, S. Chordas Iii
Journal of the Arkansas Academy of Science
Often, interesting and important observations of vertebrate distribution and natural history are not published because they are not part of a larger study. Knowledge of small details, however, not only fills gaps in understanding but also lead researchers to interesting questions about ecological relationships or environmental change. We have compiled recent observations of importance that can add immensely to the growth of knowledge of the biology of vertebrates in Arkansas.

Dna Barcoding Of The First Recorded American Burying Beetle, Nicrophorus Americanus, In Clark County, Arkansas, J. Kelly, T. Files, N. Reyna, B. Baley
Journal of the Arkansas Academy of Science
The American Burying Beetle (ABB), Nicrophorus americanus, is a red-listed endangered species under the Endangered Species Act (16 U.S.C. 1531 et seq.). We serendipitously recorded 3 individuals of this species during a forensic study in the summer of 2013. These specimens represent the first known records for Clark County, AR and the southeastern-most record in the State since the extirpation of the species from the region in the late 1800’s. Two males and one female were collected, photographed, sexed and measured. One male specimen was deceased upon discovery. The remaining two individuals were released. The U.S. Fish and Wildlife Service …

Proportionality Between Population Descriptors (Covariables) In An Aggregated Acanthocephalan (Helminth) Infection Of A Microcrustacean: Crofton Revisited, J. J. Daly Sr., K. Wagner
Proportionality Between Population Descriptors (Covariables) In An Aggregated Acanthocephalan (Helminth) Infection Of A Microcrustacean: Crofton Revisited, J. J. Daly Sr., K. Wagner
Journal of the Arkansas Academy of Science
We have previously shown that population parameters of the trematode metacercariae of Clinostomum marginatum in black bass (Micropterus spp.) were closely correlated with each other with the exception of prevalence (Daly et al. 2007, Daly (2014). Crofton (1971) and Haynes and Nicholas (1963) published raw data on an acanthocephalan, (Polymorphus minutus) in an amphipod intermediate host collected on 6 different sites on a stream. That data was used herein to examine similar correlations, as with Clinostomum, to see if another helminth infection, in this case from a different phylum, also had similar descriptor relationships. Forty one regression analyses were done …

Impacts Of Man-Made Structures On Avian Community Metrics In 4 State Parks In Northwestern Arkansas, R. D. Keith, B. Grooms, R. E. Urbanek
Impacts Of Man-Made Structures On Avian Community Metrics In 4 State Parks In Northwestern Arkansas, R. D. Keith, B. Grooms, R. E. Urbanek
Journal of the Arkansas Academy of Science
Avian community metrics often differ between areas with no human disturbance and areas with high levels of human disturbance. However, the relationships between avian community metrics and smaller-scale disturbances are not as clear. Our goal was to investigate if avian abundance, richness, evenness, and diversity differed in areas with and without small-scale human developments. We used fixed-radius 50-m avian point counts to compare points which contained a man-made structure (n = 47), such as a picnic area, road, or campsite to those that did not contain a man-made structure (n = 181) at 4 state parks in Arkansas during 18 …
Infection With The Sand Flea Tunga Penetrans (Tungiasis) In A Traveller Returning From Cameroon, Africa, D. J. Richardson, A. M. Mangili
Infection With The Sand Flea Tunga Penetrans (Tungiasis) In A Traveller Returning From Cameroon, Africa, D. J. Richardson, A. M. Mangili
Journal of the Arkansas Academy of Science
Tungiasis refers to human infection with adult fleas, Tunga penetrans. Although common throughout the tropics, tungiasis is rarely encountered by physicians in the United States such that it may be improperly diagnosed and inappropriately treated. We provide a case report of tungiasis in a traveler from Cameroon and a brief review of reported cases in the United States and Canada.
