Feral Swine Management For Conservation Of An Imperiled Wetland Habitat: Florida’S Vanishing Seepage Slopes, Richard M. Engeman, Amanda Stevens, John Allen, Jon Dunlap, Marty Dunlap, Dennis Teague, Bernice Constantin

United States Department of Agriculture Wildlife Services: Staff Publications

Only 1% of the original extent of Florida’s seepage slope habitat remains, with Eglin Air Force Base containing some of the largest tracts. Feral swine damage is one of the greatest threats to this wetland habitat.We conducted a multi-year study to evaluate the impacts of sport hunting and supplemental swine removal on damage to seepage slopes. Prior to initiation of removal in 2003, swine damage to seepage slopes in the portion of the base closed to hunting averaged 25.0%, over twice the 10.9% losses in the portion open to hunting. After less than one year of supplemental removal, damage in …

Mountain Beaver Home Ranges, Habitat Use, And Population Dynamics In Washington, W. M. Arjo, R. E. Huenefeld, D. L. Nolte

United States Department of Agriculture Wildlife Services: Staff Publications

The mountain beaver (Aplodontia rufa (Rafinesque, 1817)), endemic to western North America, is the only extant member of the family Aplodontidae. Limited information on movements and habitat use throughout the species' range is available. We radio-collared 41 mountain beavers to determine home ranges, dispersal, habitat use, and population densities on two managed forest sites in coastal Washington. Both sites were recently harvested for timber. The Donovan site (16.6 ha) was treated with herbicide before seedling planting and the Sylvia site (8.9 ha) was not treated. Mountain beaver home ranges (Donovan: 4.18 ± 0.81 ha; Sylvia: 1.39 ± 0.4 ha) …

Rad51c Deficiency In Mice Results In Early Prophase I Arrest In Males And Sister Chromatid Separation At Metaphase Ii In Females, Sergey Kuznetsov, Manuela Pellegrini, Kristy Shuda, Oscar Fernandez-Capetillo, Yilun Liu, Betty K. Martin, Sandra Burkett, Eileen Southon, Debananda Pati, Lino Tessarollo, Stephen D. West, Peter J. Donovan, Andre Nussenzweig, Shyam K. Sharan

Department of Biochemistry and Molecular Biology Faculty Papers

RAD51C is a member of the RecA/RAD51 protein family, which is known to play an important role in DNA repair by homologous recombination. In mice, it is essential for viability. Therefore, we have generated a hypomorphic allele of Rad51c in addition to a null allele. A subset of mice expressing the hypomorphic allele is infertile. This infertility is caused by sexually dimorphic defects in meiotic recombination, revealing its two distinct functions. Spermatocytes undergo a developmental arrest during the early stages of meiotic prophase I, providing evidence for the role of RAD51C in early stages of RAD51-mediated recombination. In contrast, oocytes …

Conflict Between Translation Initiation And Elongation In Vertebrate Mitochondrial Genomes, Xuhua Xia, Huang Huang, Malisa Carullo, Esther Betran, Estuko N. Moriyama

Papers in Genetics

The strand-biased mutation spectrum in vertebrate mitochondrial genomes results in an AC-rich L-strand and a GT-rich H-strand. Because the L-strand is the sense strand of 12 protein-coding genes out of the 13, the third codon position is overall strongly AC-biased. The wobble site of the anticodon of the 22 mitochondrial tRNAs is either U or G to pair with the most abundant synonymous codon, with only one exception. The wobble site of Met-tRNA is C instead of U, forming the Watson- Crick match with AUG instead of AUA, the latter being much more frequent than the former. This has been …

Hemoglobin Function And Physiological Adaptation To Hypoxia In High-Altitude Mammals, Jay F. Storz

Jay F. Storz Publications

Understanding the biochemical mechanisms that enable high-altitude animals to survive and function under conditions of hypoxic stress can provide important insights into the nature of physiological adaptation. Evidence from a number of high-altitude vertebrates indicates that modifications of hemoglobin function typically play a key role in mediating an adaptive response to chronic hypoxia. Because much is known about structure– function relationships of mammalian hemoglobins and their physiological role in oxygen transport, the study of hemoglobin variation in high-altitude mammals holds much promise for understanding the nature of adaptation to hypoxia from the level of blood biochemistry to the level of …

The Study Of Adaptation And Speciation In The Genomic Era, Jay F. Storz, Hopi E. Hoekstra

Jay F. Storz Publications

The availability of complete genome sequences and genetic linkage maps for a growing number of mammalian species is opening up exciting new opportunities for studies of evolutionary change in natural populations. For example, multilocus mapping approaches hold the promise of identifying the specific genetic changes that underlie ecological adaptation and reproductive isolation. The fact that many of the genomic resources that have been developed for Mus and Rattus are transferable to other muroid rodents means that roughly 25% of all mammalian species can now be considered ‘‘genome-enabled’’ study organisms to varying degrees. The transferability of genomic resources between model organisms …

Purification Method Directly Influences Effectiveness Of An Epidermal Growth Factor-Coupled Targeting Agent For Noninvasive Tumor Detection In Mice, Joy L. Kovar, William M. Volcheck, Jiyan Chen, Melanie A. Simpson

Department of Biochemistry: Faculty Publications

Receptor targeting is an effective method of enhancing fluorescence signal in tumors for optical imaging. We previously used epidermal growth factor (EGF) conjugated to IRDye 800CW to detect and track orthotopic prostate tumors in mice. In this study, our goal was to identify a reliable assay for targeting agent integrity in vitro that correlated with signal strength in vivo. Binding of IRDye 800CW EGF to intact A431 human epidermoid carcinoma cells was quantified in a microplate assay. Specificity was confirmed by competition with unlabeled EGF or monoclonal antibody blocking. Biological activity of intact and damaged targeting agents relative to unlabeled …

Serologic Evidence Of West Nile Virus Exposure In North American Mesopredators, Kevin T. Bentler, Jeffrey S. Hall, J. Jeffrey Root, Kaci Klenk, Brandon S. Schmit, Bradley F. Blackwell, Paul C. Ramey, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

Sera from 936 mammalian mesopredators (Virginia opossums, gray foxes, striped skunks, hooded skunks, raccoons, a bobcat, and a red fox) were collected during 2003 and 2004 in California, Arizona, Texas, Louisiana, Ohio, and Wyoming and screened for flavivirus-specific antibodies by an epitope-blocking enzyme-linked immunosobent assay (blocking ELISA). Serum samples positive for antibodies against flaviviruses were screened for West Nile virus (WNV)– specific antibodies by blocking ELISA and selectively confirmed with plaque-reduction neutralization tests. High prevalence rates were observed in raccoons (45.6%) and striped skunks (62.9%). The high WNV antibody prevalence noted in mesopredators, their peridomestic tendencies, and their overall pervasiveness …

Bioeconomic Analysis Of Herpetofauna Road-Kills In A Florida State Park, Stephanie A. Shwiff, Henry T. Smith, Richard M. Engeman, Robert M. Barry, Robin J. Rossmanith, Mark Nelson

United States Department of Agriculture Wildlife Services: Staff Publications

Road-kills are a major cause of mortality for a wide variety of herpetofauna, but management decisions on remediation procedures for reducing losses are based in economic realities. Because funding is finite for species conservation, bioeconomic analysis can assist in justifying, evaluating, and maximizing returns on conservation expenditures, especially for low-profile species such as herpetofauna. Here, we present a bioeconomic analysis of road-killed herpetofauna in Jonathan Dickinson State Park, Florida. Road surveys were conducted daily for four years to identify and enumerate the numbers of each reptile and amphibian species killed by vehicles. Conservative individual valuations applied to the losses formed …

Influence Of Land Use And Climate On Wetland Breeding Birds In The Prairie Pothole Region Of Canada, G. M. Forcey, G. M. Linz, W. E. Thogmartin, W. J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Bird populations are influenced by a variety of factors at both small and large scales that range from the presence of suitable nesting habitat, predators, and food supplies to climate conditions and land-use patterns. We evaluated the influences of regional climate and land-use variables on wetland breeding birds in the Canada section of Bird Conservation Region 11 (CA-BCR1 I ) , the Prairie Potholes. We used bird abundance data from the North American Breeding Bird Survey, land-use data from the Prairie Farm Rehabilitation Administration, and weather data from the National Climatic Data and Information Archive to model effects of regional …

A Quandary In Law? A (Qualified) Catholic Denial, Patrick Mckinley Brennan

San Diego Law Review

What I shall argue, more specifically, is that, on the view of traditional Catholic philosophy and theology, we cannot be in a true quandary in law, because - whether we readily admit it or fiercely deny it - we have received, and therefore can make, law. On the traditional Catholic view, it is a fact about who we are that we are capable of making law. While the Catholic tradition denies, then, that we are in an ontic (as opposed to ontological) quandary, it also acknowledges that the mainstream, "meager" ontologies of our making can undermine our resources for making …

People As Resources: Recruitment And Reciprocity In The Freedom-Promoting Approach To Property, Jedediah Purdy

Duke Law Journal

Theorists usually explain and evaluate property regimes either through the lens of economics or by conceptions of personhood. This Article argues that the two approaches are intertwined in a way that is usually overlooked. Property law both facilitates the efficient use and allocation of scarce resources and recognizes and protects aspects of personhood. It must do both, because human beings are both resources for one another and the persons whose moral importance the legal system seeks to protect. This Article explores how property law has addressed this paradox in the past and how it might in the future. Two bodies …

Can Our Learners Model In Mathematics?, Vimolan Mudaly

The Mathematics Enthusiast

Mathematical modeling of real world conditions should be part ofl mathematics classroom activities. In this paper I argue that when real world problems are taught at schools learners are not able to cope on their own, without the assistance of their educator. There is very little or no emphasis placed on this aspect of mathemtics at schools, although it is just beginning to make an appearance in our new Outcomes Based Curriculum. I also discuss an experiment conducted with Grade 10 learners (15 year old) and their responses to real world problems and the conditions that need to be considered. …

The Effectiveness Of Extension In-Service Training By Distance: Perception Versus Reality, Brian M. Mccann

Journal of Extension

The study reported here investigated the perceptions of Extension personnel towards Internet-based instruction delivered in two different formats: a minimally interactive online environment and a multimedia-rich, highly interactive online environment. A traditionally face-to-face environment was also studied, and posttest scores were evaluated to investigate the achievement differences between the different learning formats. Results indicate that while the traditional face-to-face instructional environment was perceived more favorably than the Internet-based environment, the multimedia-rich, highly interactive online environment was found to return just as statistically significant posttest results as those found in the more traditional learning environment.

Effect Of Age-At-Weaning And Post-Weaning Management On Performance And Carcass Characteristics Of Angus Steers, John F. Grimes, Francis L. Fluharty, Thomas B. Turner, Henry N. Zerby

Journal of Extension

Recent developments in beef marketing have created more opportunities for producers to reap greater financial rewards based on the carcass merit of the animal. Increased premiums are being offered for animals that excel in the USDA's Quality or Yield Grade scoring systems. There is an increasing focus on beef tenderness with today's consumer. Producers need to understand how on-farm production practices can affect feedlot performance and carcass merit. This study utilized 75 Angus steers to determine the effects of age-at-weaning and post-weaning management on performance and carcass characteristics of steers.

Promoting A Consistent Food Safety And Quality Message To The Dairy Industry: An Updated Resource For Extension Faculty, Veterinarians, And Dairy Advisors, Joseph C. Dalton, Dale A. Moore, Michael L. Poe

Journal of Extension

A team from seven western states developed educational resources providing a consistent meat safety and quality message to dairy producers, farm advisors, and veterinarians. The team produced a Web site and CD-ROM, DairyBeef: Maximizing Quality & Profits, consisting of videos, narrated slide sets, and on-farm tools. An additional project translated much of the curriculum into language appropriate for farm labor in both English and Spanish. DairyBeef: Maximizing Quality & Profits will help Extension faculty, veterinarians, and dairy advisors assist dairy producers and their employees in understanding market cattle food safety and quality issues and management practices to address them.
