Use Of Anti-Mullerian Hormone To Select For Fertility In Beef Heifers, Hannah Newberry, Beth Kegley, Charles Rosenkrans, Rick Rorie
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
A study was conducted to determine whether concentration of serum Anti-Mullerian Hormone (AMH) at weaning and/or breeding could predict subsequent fertility in beef heifers. Frequency distribution was used to assign serum AMH concentration measured at weaning, breeding, and the change from weaning to breeding into quartiles. Comparison of heifers based on serum AMH quartiles at weaning failed (P ≥ 0.35) to detect any effect of AMH on subsequent heifer cyclicity at breeding, estrous response after synchronization, artificial insemination (AI) pregnancy rate, overall breeding season pregnancy rate, or estimated estrous cycle of the breeding season when conception occurred. Based on AMH …

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
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 …
Population Sampling Of Chelonians In An Urban Lake In Jonesboro, Craighead County, Arkansas, J. D. Konvalina, C. S. Thigpen, S. E. Trauth
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 …

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
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.

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 …
