A Large-Sample Qtl Study In Mice: Ii. Body Composition, Joao L. Rocha, Eugene J. Eisen, L. Dale Van Vleck, Daniel Pomp Jan 2004

A Large-Sample Qtl Study In Mice: Ii. Body Composition, Joao L. Rocha, Eugene J. Eisen, L. Dale Van Vleck, Daniel Pomp

Department of Animal Science: Faculty Publications

Using lines of mice having undergone long-term selection for high and low growth, a large-sample (n = ~1,000 F2) experiment was conducted to gain further understanding of the genetic architecture of complex polygenic traits. Composite interval mapping on data from male F2 mice (n = 552) detected 50 QTL on 15 chromosomes impacting weights of various organ and adipose subcomponents of growth, including heart, liver, kidney, spleen, testis, and subcutaneous and epididymal fat depots. Nearly all aggregate growth QTL could be interpreted in terms of the organ and fat subcomponents measured. More than 25% of QTL detected map …

Comparison Of Longhorn- And Red Poll-Sired Calves From Crossbred Dams Calving At Two Or Three Years Of Age, X H. Liu, A Perez Marquez, L. V. Cundiff, L. D. Van Vleck Jan 2004

Comparison Of Longhorn- And Red Poll-Sired Calves From Crossbred Dams Calving At Two Or Three Years Of Age, X H. Liu, A Perez Marquez, L. V. Cundiff, L. D. Van Vleck

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Calving difficulty, survival from birth to weaning, birth weight, and weaning weight of 167 calves and carcass traits of 88 cattle (63 for adjusted fat thickness) were compared for progeny of Red Poll and Longhorn bulls mated to crossbred cows that calved at 2 or 3 yr of age. Results indicated that Longhornsired calves required 28% less assistance at calving than Red Poll-sired calves when dams calved at 2 yr of age (P<0.05), but there was no difference between Red Poll- and Longhorn-sired calves for calving difficulty with 3- yr-old cows. Red Poll-sired calves had significantly greater birth and weaning BW than did Longhorn-sired calves for 2-yrold dams. Significant differences attributable to sire breed were found only for bone percentage of progeny of 3-yr-old dams, but not for carcass weight, fat thickness, longissimus area, USDA quality grades, and percentages retail product, fat trim, or bone. There was a significant interaction between sire breed and age of dam only for calving difficulty. Within sire breed, calving difficulty of 2- yr-old dams was greater than that for 3- yr-old dams, and calves from 2-yr-old dams also were significantly lighter at weaning than were calves from 3-yr-old dams (P<0 .01).


A New Subspecies Of Cicindela Nevadica Leconte (Coleoptera: Carbidae: Cicindelinae) From The Badlands Of South Dakota, Stephen M. Spomer Jan 2004

A New Subspecies Of Cicindela Nevadica Leconte (Coleoptera: Carbidae: Cicindelinae) From The Badlands Of South Dakota, Stephen M. Spomer

University of Nebraska State Museum: Entomology Papers

A new subspecies of Cicindela nevadica LeConte, Cicindela nevadica makosika Spomer, is described from the South Dakota Badlands. Geographically, the population occurs at the periphery of the range of C. nevadica knausii Leng. However, this new population is geographically isolated from the nearest C. n. knausii populations, which occur ca. 100 air miles north and over 100 air miles south. Phenotypically, C. n. makosika appears most similar to C. n. tubensis Cazier from northeast Arizona. A possible threat to this population is habitat destruction by cattle.


Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson Jan 2004

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson

Faculty Scholarship

Large mammal populations theoretically are best conserved in landscapes where large protected areas are surrounded by buffer zones, connected by corridors, and integrated into a greater ecosystem. Multi-use buffer zones, including those containing complex agroforestry systems, are promoted as one strategy to provide both economic benefits to people and conservation benefits to wildlife. We use the island of Sumatra, Indonesia to explore the benefits and limitations of this strategy. We conclude that conservation benefits are accrued by expanding the habitat available for large mammals but more attention needs to be focused on how to reduce and respond to human–wildlife conflict …

Evaluation Of Feeding Varying Levels Of Wet Distillers Grains With Solubles As Compared To Dry Distilelrs Grains With Solubles To Finishing Steers, Kristina S. Mateo, Kent E. Tjardes, Cody L. Wright, Tanya J. Koger, Bradley D. Rops

South Dakota Beef Report, 2004

A study was conducted to determine the effects of implants and transportation on the metabolic status of feedlot steers. Steers (n = 28) were sorted by body weight, allocated into light or heavy blocks, and randomly assigned to one of two treatments. Treatments included non-implanted controls (CON) and steers implanted with Synovex Plus 70 d prior to harvest (IMP). Jugular blood and muscle biopsy samples (longissimus dorsi (LD) and semimembranosis (SM)) were collected 70 d post-implant, prior to transit. Steers were transported to Schuyler, NE, where blood and biopsy sampling was repeated. After harvest, carcass data were collected and muscle …

The Ecology And Natural History Of The Northern Leopard Frog, Rana Pipiens Schreber, In West Virginia, William Bradley Sutton

Theses, Dissertations and Capstones

The purpose of this study was to gather ecological and life history data for the Northern Leopard Frog, Rana pipiens Schreber, in West Virginia. In Chapter 1, natural history data, such as morphometrics (larval and adult), dorsal coloration, and emergence time were recorded. In Chapter 2, it was discovered that Aeromonas hydrophila and Pseudomonas ssp. skin infections affecting R. pipiens could be identified using BIOLOG analysis. The scope of Chapter 3 was to analyze habitat partitioning between 3 sympatric anurans (R. pipiens, R. catesbeiana, and R. clamitans melanota). The following habitat partitioning gradient was discovered. Rana …


Minnesota Banded Darters (Etheostoma Zonale) Exhibit A High Degree Of Genetic Similarity In Mitochondrial Dna Sequences Occurrence, Jean Porterfield, Molly Fee, Jessica Theorin Jan 2004

Minnesota Banded Darters (Etheostoma Zonale) Exhibit A High Degree Of Genetic Similarity In Mitochondrial Dna Sequences Occurrence, Jean Porterfield, Molly Fee, Jessica Theorin

Journal of the Minnesota Academy of Science

Hylogeography, or the historical interpretation of population genetic data, is a useful tool for addressing historical processes like the colonization history of organisms. North American freshwater fishes have experienced glacial ebb and flow in their relatively recent past (as little as 10,000 years before present in Minnesota), and studies of variation in intraspecific DNA sequences of these fishes can shed light on their radiations into previously glaciated areas. This study assessed intraspecific variation in two mitochondrial genes of the banded darter (Etheostoma zonale) from seven Minnesota localities. A high degree of similarity was found among all individuals in the study. …

Renesting Decisions And Annual Fecundity Of Female Dickcissels (Spiza Americana) In Illinois, Jeffery W. Walk, Kevin Wentworth, Eric L. Kershner, Eric K. Bollinger, Richard E. Warner Jan 2004

Renesting Decisions And Annual Fecundity Of Female Dickcissels (Spiza Americana) In Illinois, Jeffery W. Walk, Kevin Wentworth, Eric L. Kershner, Eric K. Bollinger, Richard E. Warner

Faculty Research & Creative Activity

T.-Renesting decisions and annual fecundity are crucial for interpreting other demographic information, yet are infrequently reported. We used radiotelemetry to monitor female Dickcissels (Spiza americana) throughout the 1999 and 2000 breeding seasons in south- eastern Illinois. Overall fecundity (regardless of whether females remained in the study area throughout the breeding season) was 0.61 ? 0.13 female fledglings per year. Of females that re- mained within the study area, 94% fledged young (1.25 ? 0.15 female fledglings per year). Most females (62%) that experienced nest failure emigrated from the study area (moved >10 km) in 2.8 ? 0.6 days; others (36%) …


Unusual Behavior By Bison, Bison Bison, Toward Elk, Cervus Elaphus, And Wolves, Canis Lupus, L. David Mech, Rick T. Mcintyre, Douglas W. Smith Jan 2004

Unusual Behavior By Bison, Bison Bison, Toward Elk, Cervus Elaphus, And Wolves, Canis Lupus, L. David Mech, Rick T. Mcintyre, Douglas W. Smith

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Incidents are described of Bison (Bison bison) in Yellowstone National Park mauling and possibly killing a young Elk (Cervus elaphus) calf, chasing wolves (Canis lupus) off Elk they had just killed or were killing, and keeping the wolves away for extended periods. During one of the latter cases, the Bison knocked a wolf-wounded Elk down. Bison were also seen approaching wolves that were resting and sleeping, rousting them, following them to new resting places and repeating this behavior. These behaviors might represent some type of generalized hyper-defensiveness that functions as an anti-predator strategy.

Natural History And Sexual Dimorphism Of The Eastern Hellbender, Cryptobranchus A. Alleganiensis, Robert Makowsky Jan 2004

Natural History And Sexual Dimorphism Of The Eastern Hellbender, Cryptobranchus A. Alleganiensis, Robert Makowsky

Theses, Dissertations and Capstones

The Eastern Hellbender’s natural history and morphology was examined. Field studies were done to examine the efficacy of different techniques (focusing on capturing larva) and diet analysis. Lab studies were done to determine if any sexual dimorphism exists in hellbenders using simple measurements (and ratios) and if this dimorphism could be used to reliably determine gender. Field studies were inconclusive due to the inability to find a reliable sample because of record rainfall. Lab studies revealed that a dimorphism does exist for one ratio (TG/TL, P=.048) and for several measurements. These measurements alone were not applicable for determining gender. …

Demographics And The Ecological Role Of The Channel Catfish (Ictalurus Punctatus) In Commercially Exploited And Unexploited Reaches Of The Wabash River With Implications For The Flathead Catfish (Pylodictis Olivaris), Robert Colombo

Faculty Research & Creative Activity

Catfish are a major component of the Wabash River fish assemblage and are commercially fished below river kilometer (Rkm) 500. From Rkm 322 through 499 the commercial fishery is subjected only to Indiana fishing regulations. In this reach of river, there is a 254-mm minimum total length limit on both sport and commercially harvested catfish. Below RM 322, the Wabash River forms the state boundary of Indiana and Illinois. In this region of river there are two different length limits on commercially harvested catfish with Indiana having a 254-mm length limit and Illinois having a 381-mm length limit. There is …

Breed Comparisons Of Weight, Weight Adjusted For Condition Score, Height, And Condition Score Of Beef Cows, J. A. Arango, L. V. Cundiff, L. D. Van Vleck

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Breeds were compared for differences in BW (n = 56,731), heights (n = 51,407) and body condition scores (BCS, n = 56,371) of 2- to 8-yr-old cows from four cycles of the Germplasm Evaluation (GPE) Program at the U. S. Meat Animal Research Center (U.S. Meat Animal Research Center). Angus, Hereford, and topcross cows from 22 breeds of sires were produced. The mixed model for repeated measures of BW, height, and BCS included random additive genetic and permanent environmental effects of the cow. Differences among crosses were significant for all traits. In general, BW, …


New Alleles In Calpastatin Gene Are Associated With Meat Quality Traits In Pigs, Daniel C. Ciobanu, John W. M. Vleck, S. M. Lonergan, H. Thomsen, J. C. M. Dekkers, G. S. Plastows, M. F. Rothschild Jan 2004

New Alleles In Calpastatin Gene Are Associated With Meat Quality Traits In Pigs, Daniel C. Ciobanu, John W. M. Vleck, S. M. Lonergan, H. Thomsen, J. C. M. Dekkers, G. S. Plastows, M. F. Rothschild

Department of Animal Science: Faculty Publications

Suggestive QTL affecting raw firmness scores and average Instron force, tenderness, juiciness, and chewiness on cooked meat were mapped to pig chromosome 2 using a three-generation intercross between Berkshire and Yorkshire pigs. Based on its function and location, the calpastatin (CAST) gene was considered to be a good candidate for the observed effects. Several missense and silent mutations were identified in CAST and haplotypes covering most of the coding region were constructed and used for association analyses with meat quality traits. Results demonstrated that one CAST haplotype was significantly associated with lower Instron force and cooking loss and …


Duck Nesting On Rotational And Continuous Grazed Pastures In North Dakota, Robert K. Murphy, Darrell J. Schindler, Richard D. Crawford Jan 2004

Duck Nesting On Rotational And Continuous Grazed Pastures In North Dakota, Robert K. Murphy, Darrell J. Schindler, Richard D. Crawford

United States Fish and Wildlife Service: Publications

To improve the economic viability of grazed prairie and thus conserve it as wildlife habitat, the Prairie Pothole Joint Venture (PPJV) cost-shares establishment of rotational cattle grazing on privately owned, native rangeland. During 1996 and 1997 we evaluated duck nest density, nest success, and nesting habitat on six PPJV rotational grazed pastures on the Missouri Coteau landform in central and northwestern North Dakota. Each rotational pasture was paired with a traditional, continuous grazed pasture for comparison. We located 444 nests of eight duck species. We detected no differences (P > 0.1) between rotational and continuous grazed pastures in apparent nest density …

High Abundance Of Nesting Long-Eared Owls In North Dakota, Robert K. Murphy, Laura J. Rosenfield, Robert N. Rosenfield, Melvin P. Nenneman

United States Fish and Wildlife Service: Publications

The long-eared owl (Asio otus) is a secretive, poorly understood species in the Great Plains of the United States and Canada. In North Dakota the long-eared owl has been considered a species of special concern (Petersen 1991), due mainly to lack of information on its occurrence and nesting status. We discovered 39 long-eared owl nests while searching for Cooper's hawk (Accipiter cooperii) nests in northwestern and north central North Dakota during April and May 2000. Long-eared owl nests mainly were observed at J. Clark Salyer and Des Lacs National Wildlife Refuges (NWRs) in the Souris River …

United States Fish and Wildlife Service: Publications

Intensive non-native removal in 2004 on the upper San Juan River marked the fourth year of such efforts. A total of 6,925 channel catfish Ictalurus punctatus and 1,216 common carp Cyprinus carpio were removed from RM’s 166.6 – 147.9 during 10 removal trips. Of the 10 trips, 6 were conducted from PNM Weir to Hogback Diversion (RM’s 166.6 – 159.0) and four from Hogback Diversion to Shiprock Bridge, New Mexico (RM’s 158.8 – 147.9). In addition to intensive removal efforts, opportunistic removal during riverwide monitoring trips continued in 2004.

Environmental Contaminants Associated With A Swine Concentrated Animal Feeding Operation And Implications For Mcmurtrey National Wildlife Refuge, Matthew S. Schwarz, Kathy R. Echols, Mark J. Wolcott, Karen J. Nelson Jan 2004

Environmental Contaminants Associated With A Swine Concentrated Animal Feeding Operation And Implications For Mcmurtrey National Wildlife Refuge, Matthew S. Schwarz, Kathy R. Echols, Mark J. Wolcott, Karen J. Nelson

United States Fish and Wildlife Service: Publications

Waste generated by concentrated animal feeding operations (CAFOs) may contain a variety of contaminants including nutrients, pathogens, trace elements, antibiotics, and hormones. In 2000, the U.S. Fish and Wildlife Service began to characterize CAFO contaminants in lagoons, canals, and created wetlands operated by Hastings Pork, a large swine CAFO adjacent to McMurtrey National Wildlife Refuge (McMurtrey) in Clay County, Nebraska. The created wetlands were designed to attract waterfowl; therefore, the primary purpose of this research was to evaluate whether migratory waterfowl were likely exposed to CAFO contaminants. A secondary research objective was to determine if created wetland water was suitable …


Review: Re-Evaluation Of Phosphorus Requirements And Phosphorus Retention Of Feedlot Cattle, H. C. Block, G. E. Erickson, T. J. Klopfenstein Jan 2004

Review: Re-Evaluation Of Phosphorus Requirements And Phosphorus Retention Of Feedlot Cattle, H. C. Block, G. E. Erickson, T. J. Klopfenstein

Department of Animal Science: Faculty Publications

Phosphorus requirement recommendations for cattle are important for preventing over-feeding of P and excessive P excretion. Improved precision in managing P nutrition can reduce feedlot waste management concerns. Current beef recommendations (NRC, 1996) fail to account for absorption coefficient variation related to P source, whereas dairy recommendations (NRC, 2001) change absorption coefficients with P source. Maintenance and BW gain requirements for absorbed P do not represent underlying relationships. Maintenance P requirements reflect endogenous P loss arising from failure to reabsorb salivary P. Basing maintenance requirements on saliva P secretion and re-absorption rates should improve precision of maintenance requirement estimates. Gain …
