Consequences Of Recruitmentdecisions And Heterogeneity On Age-Specific Breeding Success In A Long-Lived Seabird, Lise M. Aubry, David N. Koons, Jean Yves Monnat, Emmanuelle Cam

Wildland Resources Faculty Publications

An individual’s age at first reproduction and investment in successive reproductive attempts are involved in mechanisms that can impede somatic repair, resulting in a decline in reproductive abilities with age (reproductive senescence). We used long-term data from the Black-legged Kittiwake, a long-lived seabird, to address the relationship between recruitment age, age-specific breeding success (BS), and reproductive senescence, while accounting for breeding experience and temporal variation in BS. We first detected late-life improvement in BS across all recruitment groups, which we recognized as ‘‘within-generation selection’’ or the selective disappearance of ‘‘frail’’ phenotypes. When such heterogeneity was accurately accounted for, we showed …

Advanced Hardware-In-The-Loop Rf Testing Assures Communication System Mission Success, Steve Williams

Small Satellite Conference

Robust Radio Frequency (RF) Communication Systems (COMMS) are vital to the success of every satellite mission. But, most RF COMMS links are subject to a wide variety of signal impairments, many of which are particularly acute with small satellites. Powerful RF COMMS modeling and simulation techniques have emerged to assure the performance of these vital communications systems. Even greater assurance is possible when real-world RF signals are directly generated by the same modeling and simulation systems, and are liberally used for component-level and full-system test. For effective and full-coverage flight COMMS and/or ground COMMS testing, RF Channel Simulators must augment …

Selective Herbivory By The Desert Woodrat (Neotoma Lepida) On Joshua Trees (Yucca Brevifolia), Monte P. Sanford, Nancy Huntly

Biology Faculty Publications

We studied herbivory by the desert woodrat (Neotoma lepida) on Joshua trees (Yucca brevifolia) in the Mojave Desert to determine whether N. lepida fed selectively based on leaf nitrogen content. We measured leaf nitrogen content and the location and amount of herbivory by woodrats on Y. brevifolia trees in southwestern Utah, USA. Neotoma lepida removed the outer tips of leaves (1/3 to 2/3 of total leaf length) but left leaf bases, which had lower nitrogen content, uneaten. Herbivory by N. lepida also was concentrated on rosettes that were oriented south, and these had significantly higher nitrogen …

Comparison Of Ambient Ammonia Measurement Techniques From Dairy Area Sources, Emyrei Reese, Randal S. Martin, Cassi Going, Eve Fowels, Ron Sheffield, Mario De Haro Marti

Space Dynamics Laboratory Publications

Previous studies of ag-related NH3 concentrations and/or emissions have used a variety of techniques, with very few studies offering adequate instrumental comparisons. In the fall of 2007, NH3 concentrations/emissions were monitored for a one week period at a waste treatment lagoon on a 6000-cow dairy in Idaho using five separate methodologies. Up to twenty-five Ogawa passive samplers were dispersed around the perimeter of the lagoon, with a concentrated bank of samplers arrayed along the predicted downwind side of the facility. A URG acid/base gas denuder system, assembles with three series denuders configured for NH3 collection, was collocated at a single …

The Influence Of Mastication On Soils And Fuels In Moist And Dry Forests Of The Northern Rocky Mountains, Theresa Jain, Russel T. Graham

North American Forest Ecology Workshop

We evaluated the applicability of mastication as a fuel treatment alternative within Northern Rocky Mountain moist and dry forests to treat post-harvest activity slash (moist forest) and standing trees (dry forest). On the moist forest site, we compared four different slash treatments, mastication, machine grapple piling, lop and scatter, and a control within a wildland urban interface setting to determine the effects of these treatments on soil nutrition, forest floor depth, and woody debris distributions. We randomly assigned the slash treatments and controls to 12 one-acre plots. Nitrogen, soil carbon, and magnesium concentrations within the soil components were not significantly …

Measurement Of Functional Residual Capacity Of The Lung By Nitrogen Washout, Carbon Dioxide Rebreathing And Body Plethysmography In Healthy Volunteers, Lara Brewer, Joseph Orr

Utah Space Grant Consortium

Background: We measured Functional Residual Capacity (FRC) of the lungs with three methods in healthy volunteers. The three techniques included a CO₂ partial rebreathing technique, nitrogen washout technique, and the reference technique for ambulatory patients, body plethysmography.

Materials and Methods: After granting consent to an IRB-approved protocol, each of the 20 healthy volunteers participated in FRC measurement by three methods, including body plethysmography, carbon dioxide (CO₂) rebreathing, and nitrogen washout. Gas concentration and volume data were collected from the distal side of a mouthpiece during spontaneous ventilation for the washout and rebreathing measurements. The FRC was measured …

Wildlife Services And The New Administration, William H. Clay

Wildlife Damage Management Conference

To understand what can be expected from President Obama and the new Administration, we can look at past behavior. As a Senator, Obama served on the Senate Environment and Public Works Committee showing great interest in environmental issues. He believes that federally-funded scientific research should play an important role in advancing science and technology. Moreover, President Obama has declared that decisions in his Administration will be made based on science and not politics. However, the biggest change from the new Administration is emphasis on making the government work more efficiently and at a reduced cost. During the next 4 years, …

A Field-Test Of Rhodamine B As A Biomarker In Raccoons, Tricia L. Fry, Tara E. Baranowski, Brandi D. Hughey, Mike R. Dunbar

Wildlife Damage Management Conference

Rhodamine B is a dye that when ingested results in fluorescent bands in growing hair and whiskers of many mammals. Previous research at Wildlife Services’ (WS) National Wildlife Research Center (NWRC) found that rhodamine B is a successful biomarker in raccoon whiskers and that raccoons do not have a taste aversion to the dye when it comprises ≤ 3% of a bait. Our study assessed the ease of bait distribution, whisker collection, and evaluation of the biomarker for potential use in the Oral Rabies Vaccination (ORV) program administered by the WS National Rabies Management Program (NRMP). In collaboration with WS …

Genetic Analysis Of Population Dynamics Of The Southeastern Coyote (Canis Latrans), D. Dennis, J. Armstrong, W. Arjo, K. Brock, A. Piaggio

Wildlife Damage Management Conference

Coyotes (Canis latrans) have been extremely successful in dispersing and expanding their range that now includes all fifty states of the United States in addition to Canada and parts of Central America. These animals have generally been considered a pest species due to their adaptive ability, high reproductivity, and impact as a top predator on commercial agricultural business. Population dynamics of coyotes is still poorly understood, yet such knowledge would be beneficial to management of coyotes in all areas. The goal of this study is to determine population structure in Alabama by using microsatellite DNA markers. In addition …

Current Trends And The Future Of Private Sector Nuisance Wildlife Control, Kevin Clark

Wildlife Damage Management Conference

Private sector vertebrate control continually interacts with many parties-all with a genuine interest in wildlife, and thus, the industry is always changing. In recent years, people expressed a desire for more humane treatment of animals and environmentally responsible control methods. The industry has also focused on vertebrates besides birds and rodents and is working to have the opportunity to handle species that are currently excluded from permit systems in some states. In the 1990s, there was rapid growth of private sector wildlife control businesses across the U.S., and increasingly, pest control companies added wildlife services in response to customer demands. …

Alabama population growth rates have begun to soar in the last decade. A surge of new communities now exist where wildlands once stood; bringing humans into unexpected and unwanted wildlife encounters. Increasingly, citizens look to state agencies to remove unwanted animals that cause property damage or are perceived to be a threat to humans. While state agencies can provide assistance in some cases, they are not equipped to dispatch personnel to meet every individual's need. The Alabama Wildlife Damage Management website is presented as a resource for citizens to learn solutions for common wildlife damage problems in our area, learn …

Managing Meadow Vole Damage On A Natural Area Restoration Site, R. Collins, L. Humberg, G. Witmer, H. Forgione, J. Mclaughlin

Wildlife Damage Management Conference

Meadow voles (Microtus pennsylvanicus) can cause extensive damage to nursery and orchard plantings when food is scarce. Historically, significant research has been devoted to managing vole populations in agricultural or horticultural settings. Restoration of a former New York City municipal landfill to a native ecosystem has been hampered due to expanding vole populations. Due to location and sensitivity of the site, traditional methods of managing vole populations were restricted. In the fall of 2008 zinc phosphide-treated oats were applied to the site using PVC bait stations. Snap-trapping efforts indicate that the use of bait stations and zinc phosphide …

Viral Disease Surveillance In Select Wildlife Populations In Mississippi, Amanda R. Deese, Richard B. Minnis

Wildlife Damage Management Conference

Raccoons and opossums are quickly becoming a common sight in urban areas, providing a higher risk of human exposure to zoonotic pathogens. Feral swine are also becoming more common and problematic for many. We conducted serological surveys for avian influenza (AI), West Nile virus (WNV), rabies virus (RV), and canine distemper virus (CDV) in raccoons (n=119), opossums (n=126), and feral swine (n=105) in two regions of Mississippi. Raccoons had antibodies to all four viruses, while feral swine had antibody responses to WNV and opossums exhibited responses to WNV and RV. Active wildlife disease surveillance is a vital aspect of wildlife …

Classical Swine Fever Surveillance In Feral Swine, Seth R. Swafford, Brandon S. Schmit, Kerri Pedersen, Mark W. Lutman, Thomas J. Deliberto

Wildlife Damage Management Conference

Diseases such as classical swine fever (CSF) and foot-and-mouth disease have been eradicated in the United States, but possible reintroductions merit the development of an enhanced surveillance system. Important foreign animal or transboundary diseases like these pose a significant risk to the health of wildlife and livestock in the United States. Wildlife Services (WS) performs surveillance in targeted feral swine (Sus scrofa) populations as part of a comprehensive United States Department of Agriculture, Animal and Plant Health Inspection Service effort to demonstrate disease-free status in our nation's livestock and wildlife. Surveillance is based on risk assessments which identify …

Changing Attitudes, Troubled Times: Lessons Learned From Protected Species Management In Urban Environments, Sean P. Guinan

Wildlife Damage Management Conference

The United States is becoming increasingly urbanized, with nearly 80% of the American population currently residing in urban centers. This trend in human settlement patterns away from rural areas has coincided with a shift in human values and perceptions regarding the natural environment. Urban wildlife managers are therefore presented with unique challenges not experienced by managers of times past and are left having to blend principles of wildlife ecology within a changed ethical and sociological context. Standard wildlife management practices may not be appropriate for this shifting paradigm and there is an ever-increasing need for innovative and collaborative efforts that …

As the methods-development arm of the U.S. Department of Agriculture's Wildlife Services program, the National Wildlife Research Center (NWRC) is charged with developing tools and information for protecting agriculture, human health and safety, and property from problems caused by wildlife, including birds. Increasingly the NWRC is being asked to provide basic ecological information on the population status of various bird species, and its role is expanding from a reactive one of providing management options to that of predicting long-term implications of various management actions. This paper describes several areas of research by NWRC scientists to address population-level questions in support …

Dogs Gone Wild: Feral Dog Damage In The United States, David L. Bergman, Stewart W. Breck, Scott C. Bender

Wildlife Damage Management Conference

Feral dogs have been documented in all 50 states and estimates of damage in the U.S. from these animals amount to >$620 million annually. In Texas alone, it is estimated that over $5 million in damage to livestock annually can be attributed to feral dogs. We reviewed national statistics on feral dog damage reported to USDA, APHIS, Wildlife Services for a 10-year period from 1997 through 2006. Damage by feral dogs crossed multiple resource categories (e.g., agriculture, natural resources); some examples of damage include killing and affecting the behavior and habitat use of native wildlife; killing and maiming livestock; and …
