Properties Of Corneal Receptors In A Teleost Fish, Paul J. Ashley, Lynne U. Sneddon, Catherine R. Mccrohan

Veterinary Science and Medicine Collection

Corneal receptors have not previously been identified in lower vertebrates. The present study describes the properties of trigeminal ganglion corneal receptors in a teleost fish, the rainbow trout (Oncoryhnchus mykiss). Out of 27 receptors, 7 were polymodal nociceptors, 6 were mechanothermal nociceptors, 2 were mechanochemical receptors and the largest group, 12, were only responsive to mechanical stimulation. No cold responsive receptors were found on the trout cornea. Mechanical and thermal thresholds were lower and receptive field diameters smaller than those of cutaneous trigeminal receptors in the trout, demonstrating greater sensitivity in the cornea. The lack of cold sensitive neurons may …

A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores

Dairy Science

The use of a ceramic microfiltration (MF) membrane for the fractionation of buttermilk and whey buttermilk obtained from pilot scale churning of cream and whey cream from industrial sources has been studied. Whey buttermilk contained comparable amounts of phospholipids compared to regular buttermilk but its protein content was lower due to the absence of caseins. However, it was found that lipid content of whey cream did vary significantly between lots resulting in important variations in the fat content of whey buttermilk. A twofold MF concentration of regular buttermilk doubled its phospholipids content whereas that of whey buttermilk was increased by …

Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong

Dairy Science

Our aim was to investigate how two conditions of whey processing, pH and heat treatment, affect the physical properties of stirred yoghurts fortified to 45 g protein kg⁻¹ with whey protein concentrates (WPC). Cheddar whey was heated at pH 6.4 or pH 5.8 at 72 °C for 15 s, eventually heated further at 82 or 88 °C for 78 s, ultrafiltered, and spray dried. Resulting WPC contained 38% protein; the denaturation level of the whey protein was 10–53%. There were significant (P

Karyotypes Of Eight Species Of Leptodactylus (Anura, Leptodactylidae) With A Description Of A New Karyotype For The Genus, Renata Cecília Amaro-Ghilardi, Gabriel Skuk, Rafael O. De Sá, Miguel Trefaut Rodrigues, Yatiyo Yonenaga-Yassuda

Biology Faculty Publications

Karyotypes of eight species of Leptodactylus (Anura, Leptodactylidae) with a description of a new karyotype for the genus. Eight species of the Neotropical genus Leptodactylus were karyologically studied: seven of them (L. gracilis, L. mystacinus, L. petersii, L. pustulatus, L. macrosternum, L. ocellatus, L. labyrinthicus) presented 2n=22 and L. silvanimbus showed a distinctive karyotype with 2n=24. Nucleolar organizer regions (Ag-NORs) were detected in two different pairs of chromosomes: pair 4 at the proximal region of the long arm of one individual of L. mystacinus from São Paulo state and of L. petersii; and …

Genetic Resolution Of The Enigmatic Lesser Antillean Distribution Of The Frog Leptodactylus Validus (Anura, Leptodactylidae), Keneth Yanek, W. R. Heyer, Rafael O. De Sá

Biology Faculty Publications

Leptodactylus validus has an unusual distribution, inhabiting Trinidad, Tobago, and the Lesser Antilles, but not the mainland of South America. This distribution is inconsistent with other distribution patterns observed for these islands. Although slight variation in adult morphology has been observed among the different island populations of L. validus, call data suggest the presence of a single species. Calls of L. pallidirostris from Venezuela and Brazil suggested that this taxon might be conspecific with L. validus. Sequence data from the 12S and 16S mt rDNA genes indicate that L. validus represents a single species throughout its distribution and is conspecific …

The Art And Artistic Legacy Of Louis Agassiz Fuertes, Paul A. Johnsgard

Nebraska Bird Review

Perhaps some Nebraska birders will not immediately recognize the name Louis Agassiz Fuertes, as he died almost 80 years ago. Yet he influenced the art of bird painting as much as did John James Audubon, and provided wonderful artwork for many major state bird reference books. He also personally tutored George Miksch Sutton, the Nebraska-born artist and biologist who provided the NOU with its Burrowing Owl logo, and who contributed greatly to American ornithology, especially that of the southern Great Plains.

It is interesting that, like John James Audubon, Roger Tory Peterson, and George Miksch Sutton, we would never think …

The 2006 Nebraska Nest Report, Wayne Mollhoff

Nebraska Bird Review

The drought that began in 1999 continued over most of Nebraska this year, with 7 of the past 8 years receiving lower than normal rainfall. More normal rains fell in April and early May, especially in the central and east, before stopping for most of the summer. Most of the Panhandle and southwest were declared drought disaster areas by early summer, setting the stage in late July for the worst fire season in memory in the Pine Ridge area of the northern Panhandle (Fowler, 2007). Ultimately, 83 of 93 counties were declared part of the drought disaster area. Low water …

Fall Field Report, August-November 2006, W. Ross Silcock

Nebraska Bird Review

First, I want to say how much I appreciate observers' responses to my requests for additional details on various sightings, not just rarities, but early and late dates. It's important to have these details for the archives to help future readers and researchers feel more comfortable with records from our era.

Patterns that were apparent included a generally quiet fall for waterfowl (they were all at Lake McConaughy), but excellent numbers of the rarer two scoters (but NO White-winged!) and a surprising 16 Red-necked Grebes. On the other hand, numbers of staging Western Grebes were down significantly, apparently due to …

Effects Of Training And Experience On Repeatable And Reliable Assessment Of Beef Cattle Body Condition Scores, Pete Burmeister

Masters Theses & Specialist Projects

In recent years, body condition scores (BCS) have been included in Expected Progeny differences (EPD) calculations for maintenance energy. This experiment was designed to identify the acuteness at which technicians of different skill levels can correctly quantify BCS in beef cattle. Thirteen students enrolled in agriculture at Western Kentucky University were assigned to three experimental technician groups based on training level. Five members of the colligate livestock judging team with extensive cattle backgrounds were BCS trained and assigned to the experienced level, four students were BCS trained by the WKU livestock judging coach and assigned to the trained level, and …

Derelict Blue Crab Trap Impacts On Marine Fisheries In The Lower York River, Virginia, Kirk J. Havens, Donna Marie Bilkovic, David Stanhope, Kory Angstadt, Carl Hershner, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

In Virginia, an examination of existing derelict trap data retrieved from Chesapeake Bay Multispecies Monitoring and Assessment Program (ChesMMAP) trawl surveys shows the potential effect of derelict traps on fish communities in Virginia waters (Bonzek and Latour 2005). Since 2002, ChesMMAP has attempted to sample 90 stations in the mainstem Chesapeake Bay ranging from the southern edge of the Susquehanna Flats to the Bay mouth in all depths to a minimum of 10 feet during each cruise. There are approximately 4-5 cruises per year and a large mesh bottom trawl is used to capture adult fish of a variety of …

A Sex-Linked Allele, Autosomal Modifiers And Temperature-Dependence Appear To Regulate Melanism In Male Mosquitofish (Gambusia Holbrooki), Lisa Horth

Biological Sciences Faculty Publications

About 1% of male mosquitofish (Gambusia holbrooki) express melanic (mottled-black) body coloration, which differs dramatically from the wild-type, silvery-gray coloration. Here, I report on the genetic inheritance pattern of melanic coloration, which indicates Y-linkage, and at least one autosomal modifier. Phenotypic expression of melanism is also affected by temperature. Expression is constitutive ( temperature insensitive) in some populations, inducible ( temperature sensitive) in others. Constitutive and inducible expression occur among geographically proximal populations. However, males from any single population demonstrate the same constitutive or inducible expression pattern as one another. The F1 males from inter-population crosses demonstrate temperature-related …

Factors Influencing Off-Flavor In Beef, Jennie Marie James Hodgen

Department of Animal Science: Dissertations, Theses, and Student Research

Projects were conducted to increase knowledge of liver-like off-flavor origins in muscles from the beef chuck and round. Effects of cooking rate and holding time on off-flavor of various steaks from ten carcasses were determined. Off-flavor from these muscles was lowest when the steaks were cooked slowly (on a 149°C grill versus a 249°C grill) and when held for one hour prior to evaluation. The M. infraspinatus had the least off-flavor, and the M. vastus intermedius had the most intense off-flavor. These data suggest a carcass with one off-flavored muscle is likely to have other off-flavored muscles in the chuck …

Genetic Analysis Of White Marlin (Tetrapturus Albidus) Stock Structure, John Graves, Jan Mcdowell

VIMS Articles

The genetic basis of stock structure of white marlin (Tetrapturus albidus Poey, 1860) was inferred from analyses of five tetranucleotide repeat microsatellite loci (n = 214) and the mitochondrial (mt)DNA control region (n = 99) of white marlin from four geographic regions in the Atlantic Ocean. Considerable genetic variation was present in all collections for all molecular markers. Analysis of replicate collections taken in different years from three regions revealed no significant differences in the distribution of allele frequencies among years within regions. The value of global F-statistics for both multilocus microsatellite data and mtDNA control region sequences approached significance …

Detection Of Panulirus Argus Virus 1 (Pav1) In The Caribbean Spiny Lobster Using Fluorescence In Situ Hybridization (Fish), Caiwen Li, Jeffrey D. Shields, Hamish J. Small, Kimberly S. Reece, Carmony L. Hartwig, Roland A. Cooper, Robert E. Ratzlaff

Collected Faculty and Staff Scholarship

Panulirus argus Virus 1 (PaV1) is the first virus known to be pathogenic to a wild lobster. It infects the Caribbean spiny lobster P. argus from the Florida Keys, and has a predilection for juveniles. The monitoring of the virus in wild populations and study of its behavior in the laboratory require the development of reliable diagnostic tools. A sensitive and specific fluorescence in situ hybridization (FISH) assay was developed for detection of PaV1. The lower detection limit using a 110 bp DNA probe in a dot-blot hybridization for PaV1 DNA was 10 pg of cloned template PaV1 DNA and …
