The Fleas (Arthropoda: Insecta: Siphonaptera) Of Arkansas, Chris T. Mcallister, Lance A. Durden, Henry W. Robison, Matthew B. Connior

Journal of the Arkansas Academy of Science

Fleas (Insecta: Siphonaptera) are important ectoparasites of cats, dogs, other mammals (including humans), and birds, and are an important component of the biota of North America. In addition, they can be nuisance biters and serve as vectors or intermediate hosts of several flea-borne disease agents and parasites that negatively affect mammals and birds. In Arkansas, there have been no recent comprehensive summaries of fleas in the last 45+ years. Here, we provide a summary of the 29 species of fleas within 7 families that have been recorded from the state, update their taxonomy, and note their medical and veterinary importance.

Local Scale Comparisons Of Avian And Woody Vegetation Communities Within Four Arkansas State Parks, Bennett P. Grooms, Rachael E. Urbanek

Journal of the Arkansas Academy of Science

Measuring the spatial distribution of biotic communities can provide useful data to wildlife managers on how and why species assemblages differ across a landscape. During 18 May – 7 August 2015, we conducted avian point counts and collected vegetation data in nested subplots at 4 Arkansas state parks. We then used a series of one-way ANOVAs and Kruskal-Wallis tests to examine differences in species richness, Simpson’s evenness, Simpson’s diversity, and Bray-Curtis similarity across the 4 parks. Mount Magazine State Park had the lowest avian evenness (F_3,22 = 9.57 P = 0.003) and diversity (F_3,22 = 17.8 …

Muddying The Waters: Catfish Inspection Authority Transitions To The Food Safety And Inspection Service, Michelle Johnson-Weider

Journal of Food Law & Policy

The Food and Drug Administration regulates the safety and labeling of almost all food in the United States other than meat, poultry, and egg products, which fall under USDA’s Food Safety and Inspection Service (FSIS). Effective September 1, 2017, FSIS assumed inspection responsibility for catfish after years of Congressional lobbying by the small domestic catfish industry. This article examines how this unlikely legislative victory was won against free trade advocates representing much larger economic interests.

Ecology Of Blanchard Springs Caverns, Ozark National Forest, Arkansas: 42 Years Later, C. J. Midden, S. K. Sasser, J. L. Grove

Journal of the Arkansas Academy of Science

Interrelationships between subterranean and epigean environments affect dispersion and distribution of cave organisms among the macro and microhabitats. This study examined the environmental impact of 42 years of tourism and development in the two lower sections of Blanchard Springs Caverns found in Stone County, Arkansas; and contributes to a better understanding of the seasonal fluctuations of the abiotic and biotic parameters.

Temperature, water quality, and fauna data were collected. A new entrance, lighting, and approximately 12,500 visitors during the 12-month study had no observable effect on cavern temperatures. Stream water quality measurements were comparable to Grove’s 1974 study. Gray bat, …

A Description Of Variation In Fecundity Between Two Populations Of Wolf Spider Rabidosa Rabida In Searcy Arkansas Using Brood Size Measurements, Brandon Hogland, Ryan Stork, Amber Hug

Journal of the Arkansas Academy of Science

Fecundity, a very important population variable, can be estimated by measuring the number of juveniles hatching out of individual egg sacs. Rabidosa rabida is a large wolf spider that is common in Arkansas and much of the eastern portion of North America. This study attempts to expand previous estimates of variation in fecundity made for this species by Reed and Nicholas in Mississippi. We hypothesized that a significant variation would be found in fecundity estimates between two populations in Arkansas. We also hypothesized that this variation would be similar to the variation reported in Mississippi. Two populations of R. rabida …

Genetic Polymorphisms Of The Glucocorticoid Receptor And Interleulin-8 Receptor Genes And Their Relationship To Production Traits And Hair Coat Scores In Crossbred Cattle, Avery B. Deaton, Laura Meyer, Jeremy Powell, Charles F. Rosenkrans Jr.

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Little is understood about how the diversity of genes, specifically the glucocorticoid receptor (GR) and interleukin-8 receptor (CXCR2), are related to reproductive health and how this affects physical traits in cattle. Glucocorticoid receptors have been positively associated with higher milk yields, lactose content, feed intake, and feed conversion rates. Interleukin-8 genes are part of the innate immune response and help with many aspects of female reproductive health, such as protecting the embryo from the maternal immune system during pregnancy. The objective of this research was to identify polymorphisms in the GR and CXCR2 genes and to associate genotypes between the …

The Bovine Rumen Microbiome Revealed By Different Fractions Of Rumen Contents, Ashlee Breakstone, Jiangchao Zhao

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The bovine rumen microbiota is very important in terms of animal functionality and digestion. The fermentative capability of the rumen provides means for the digestion of complex plant material that is indigestible by humans. The rumen microbiota is made up of billions of microorganisms, primarily bacteria, that digest and ferment feed into volatile fatty acids and bacterial protein for the animal’s energy and protein needs, respectively. Changes to the rumen microbiota can have a direct measure on animal growth, health, and performance. The possibility of productivity boosts in the cattle industry make the rumen microbiome a hot topic in the …

Cost-Benefit Analysis Of A Genetic Marker On Cow-Calf Operations Differentiated By Pasture And Breed, Josh C. Crystal, Michael P. Popp, Nathan P. Kemper, Charles F. Rosenkrans Jr.

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Genetic sequencing in beef cattle (Bos taurus L.) is expected to aid producers with selecting breeding stock. Using data from experimental trials conducted with Angus, Brahman, and their reciprocal cross, the single nucleotide polymorphism (SNP) P450 C994G marker expression was investigated for use in selecting genetics suited to grazing endophyte-infected tall fescue (Festuca arundinacea Schreb. L.) compared to bermudagrass (Cynodon dactylon L.) pasture. The study is unique in the sense that actual cow-calf breeding failure rates (open cows were not culled) were tracked from 1991 to 1997 on herds that were bred to calf in spring and were either exposed …

Marketing Tips For Small-Scale, Local Honey Bee Keepers In Northwest Arkansas, Samuel L. Goll, Michael P. Popp, Jennie S. Popp, Donald C. Steinkraus

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The objective of this thesis was to gain market information for beekeepers regarding different honey bee products and to provide information about economic feasibility when produced on a small, local scale. Since cost-of-production information about operating an apiary is widely available, the focus of this work was on gaining marketing knowledge. One of the objectives of the surveys was to develop a better sense of what potential resellers of honey bee products considered locally produced. Another objective was to determine preferences for honey bee product packaging as well as bee pollination services. Using that feedback, a marketing plan for different …

Effects Of Labeling And Consumer Health Trends On Preferred Ground Beef Color Characteristics, Fat Content And Palatability In Simulated Retail Display, Fred W. Pohlman Ii, Fred Pohlman, Nicholas B. Anthony, Famous Yang

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Nutritional concerns have impacted the protein market, decreasing red meat consumption as well as prompting the advent of lean and extra lean ground beef. However, such lean blends of ground beef may suffer in palatability. This study seeks to bridge the gap between perceived health and palatability. Participants were asked to identify the relative importance of characteristics commonly used in purchasing ground beef and select a preferred package of ground beef from labeled and unlabeled sections consisting of 4%, 10%, 20%, and 27% fat content. Instrumental color data and their main drivers were also collected. Participants then completed a blind …

Risk Mitigation Through Diversified Farm Production Strategies: The Case In Northern Mozambique, Olivia C. Caillouet, Lawton L. Nalley, Amy L. Farmer

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Mozambique, like many other parts of the low-income world, faces perennial challenges with food security. With a rapidly growing population and arable land on the decline, sustainable agriculture is vital to managing the already depleted natural resources of Sub-Saharan Africa more effectively while increasing food security. Food security issues for subsistence farmers in most low-income countries are a product of endogenous (crop yields) and exogenous (currency fluctuations as many agricultural inputs are imported) factors. In Mozambique the value of the local currency, meticals, has decreased by approximately 50% since January 2015 compared to the U.S. dollar. While this makes exporting …

An Annotated Checklist Of The Crayfishes (Decapoda: Cambaridae) Of Arkansas, Henry W. Robison, Keith A. Crandall, Chris T. Mcallister

Journal of the Arkansas Academy of Science

Prior to the present study, 56 species with 3 additional subspecies for a total of 59 different taxa of crayfishes were recognized from Arkansas. We add a single species (Carmel Crayfish, Fallicambarus schusteri) to that list, subtract a documented synonym (Procambarus ferrugenius = Procambarus liberorum), update the classification to better reflect recent phylogenetic insights, and provide an updated annotated checklist of the 59 crayfish taxa of presently known from the state. There are 8 endemic species in Arkansas, including the Bayou Bodcau Crayfish (Bouchardina robisoni), Boston Mountains Crayfish (Cambarus causeyi), Hell Creek …

A First Look At The Microbial Community Of Rabidosa Rabida, A Wolf Spider In Searcy, Arkansas, Patricia Rivera, Ryan Stork, Amber Hug

Journal of the Arkansas Academy of Science

Many diverse animal models have been used to explore the interactions between host organisms and their microbiota. Increased understanding of microbe-host interactions could lead to improved healthcare and drug development. Spiders have venom, digestive fluid, and body fluid components that have been suggested to possess antimicrobial properties that could lead to new and interesting host-microbe interactions. While studies have been published on interactions between bacteria affecting the immune function and behavior of spiders, the spider microbiome has not been established to date. Excreta and body swabs were collected from Rabidosa rabida, a wolf spider typically found on tall grass …

Simulating Foodborne Pathogens In Poultry Production And Processing To Defend Against Intentional Contamination, S. Lankford, D. R. Thompson, S. C. Ricke

Journal of the Arkansas Academy of Science

There is a lack of data in recent history of food terrorism attacks, and as such, it is difficult to predict its impact. The food supply industry is one of the most vulnerable industries for terrorist threats while the poultry industry is one of the largest food industries in the United States. A small food terrorism attack against a single poultry processing center has the potential to affect a much larger human population than its immediate consumers. In this work, the spread of foodborne pathogens is simulated in a poultry production and processing system to defend against intentional contamination. An …

Long-Term Aquatic Invertebrate Monitoring At Buffalo National River, Arkansas, David E. Bowles, Janice A. Hinsey, Tyler Cribbs, Faron D. Usrey, Lloyd W. Morrison

Journal of the Arkansas Academy of Science

Aquatic invertebrate community structure was used to assess long-term water quality integrity in the mainstem of the Buffalo National River, Arkansas from 2005 to 2013. Nine benthic invertebrate samples were collected from each of six sampling sites using a Slack-Surber sampler. The Stream Condition Index (SCI) developed for Ozark streams was used to assess integrity of the invertebrate communities. This index is calculated using taxa richness, EPT (Ephemeroptera, Plecoptera, Trichoptera) Richness, Shannon’s Diversity Index, and Hilsenhoff Biotic Index (HBI). Sørensen’s similarity index was used to assess community similarity among sites, and scores were then analyzed using ascendant hierarchical cluster analysis. …
