Status Survey Of The Peppered Shiner, Notropis Perpallidus Hubbs And Black, In Arkansas And Oklahoma, Henry W. Robison

Journal of the Arkansas Academy of Science

The peppered shiner, Notropis perpallidus Hubbs and Black, is a small, silvery, upland stream fish found only in southwestern Arkansas and eastern Oklahoma. This fish species was studied from 1999-2001 to determine its distribution, habitat, and conservation status. A total of81 collections was made during the 2-year study; however, only 17 specimens were collected. The present distribution of the peppered shiner in Arkansas and Oklahoma is described as well as the conservation status of this cyprinid in both states.

Ichthyofaunal Assemblages In Three Approximate But Ecologically Diverse Streams In Clark County, Arkansas, C. Renn Tumlison, Scott Jordan, Lesley Self, Henry W. Robison

Journal of the Arkansas Academy of Science

Three tributaries to the Ouachita River in eastern Clark County, Arkansas, empty into the river within a collective distance of about 9 km. The streams drain basins derived from the Wilcox formation, partially overlain by terrace and alluvial deposits. Despite their proximity, the streams are very different: L'Eau Frais has a gravel substrate and was recognized by the French as a cool water stream, Tupelo Creek is a bottomland stream from which numerous Water Tupelo (Nyssa aquatica) emerge, and Saline Bayou was named due to its marked salinity. We studied the assemblages of fishes in these 3 very different drainages …

Initial Evaluation Of Novel Preparations Of Bordetella Avium By Determination Of Antibody Response Titers, Joel Gallagher, Stacy Higgins, Luc Berghman, Billy Hargis

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

The efficacy of killed vaccines generally is not equal to live vaccines. However, due to safety and ease of production, they remain a vital part of controlling and preventing diseases. In this study, the immune response to four different vaccination preparation techniques for the agent of bordetellosis of turkeys, Bordetella avium (BA), was compared. Preparation/inactivation techniques included (1) formalin inactivation, (2) opsonization of formalin-inactivated BA, (3) buffered acetic-acid BA inactivation, or (4) opsonization of buffered acetic-acid-inactivated BA. Non-adjuvated suspensions containing equal antigen mass were administered subcutaneously (0.2 mL) at day-of-hatch in all cases. For each treatment (N=40/treatment), plasma samples were …

Geographic Distribution And Harvest Dynamics Of The Eastern Spotted Skunk In Arkansas, D. Blake Sasse, Matthew E. Gompper Jan 2006

Geographic Distribution And Harvest Dynamics Of The Eastern Spotted Skunk In Arkansas, D. Blake Sasse, Matthew E. Gompper

Journal of the Arkansas Academy of Science

The eastern spotted skunk (Spilogale putorius) is a small carnivore found across much of the central and southeastern United States, and while once common, this species has become rare in most obits range. We used harvest records collected by the Arkansas Game and Fish Commission from 1941-2004 to examine historic and current distribution and long-term harvest dynamics of this species in Arkansas. Eastern spotted skunks have historically been most common in the Ozarks and the Ouachitas though the species appears to have been present, but uncommon, in the Gulf Coastal Plain and in some counties in southeastern Arkansas near the …

Prediction Of The Tenderness Of Cooked Poultry Pectoralis Major Muscles By Near-Infrared Reflectance Analysis Of Raw Meat, Bradley R. Cheatham Jan 2005

Prediction Of The Tenderness Of Cooked Poultry Pectoralis Major Muscles By Near-Infrared Reflectance Analysis Of Raw Meat, Bradley R. Cheatham

Inquiry: The University of Arkansas Undergraduate Research Journal

Tenderness in boneless poultry breast meat is of utmost importance to consumers. However, there is currently no nondestructive method to predict poultry breast meat tenderness. Textural properties of poultry breast meat were predicted by near-infrared reflectance (NIR) spectroscopy. Spectra were collected on 390 poultry Pectoralis major muscles from broiler carcasses to examine the correlation between NIR spectroscopy and the Meullenet-Owens Razor Shear (MORS) test. Two instrumental parameters (maximum shear force and total shear energy) were used as estimates of meat tenderness. Calibration (R2 cal) and validation (r2 val) coefficients of determination were used for predicting instrumental measurements using the reflectance, …

Small Fish Species Of Arkansas Reservoirs, Thomas M. Buchanan Jan 2005

Small Fish Species Of Arkansas Reservoirs, Thomas M. Buchanan

Journal of the Arkansas Academy of Science

Sixty-six Arkansas reservoirs were sampled with rotenone from 1997 through 2004 to determine the distribution and species richness of small, nongame fish species in manmade lentic environments. Eighty-five small fish species distributed among 13 families were collected. Fish distribution and species richness varied by reservoir size, ecoregion, and reservoir type. Species richness was significantly correlated with reservoir size and the number of small species occurring in reservoir drainages. Some small species apparently maintained breeding populations in reservoirs, other species occurred in low numbers and may not have maintained breeding populations, and some species occurred sporadically, probably as stragglers from nearby …
