The Interspecificity Of Distress Calls, A. T. Baxter, J. C. Bell, J. R. Allan, J. Fairclough

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

It is widely accepted that birds respond best to distress calls given by their own species. There is little information available however, which evaluates the effect of inter and intraspecific distress calls. During 1997 and 1998, distress calls from sub populations which are unfamiliar to local birds of the same species were assessed in Hong Kong and the U.K. Results were examined on a taxonomic basis. Response was found to be greater when con-specific calls were used. Response rates declined further as taxonomic relatedness decreased. Unlike other studies, distress calls of UK birds were effective on the same species in …

A Model To Determine The Severity Of A Birdstrike With Flocks Of Canada Geese, Richard Budgey, J. R. Allan

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The number of birds of a flocking species likely to be ingested into an aircraft engine in a multiple birdstrike is of profound interest to engineers when they consider birdstrike tolerance in engine design. Of even more importance than the number of birds which may enter a single engine, when power can still be supplied by the remaining engines, is the probability of more than one engine suffering an ingestion. The historical birdstrike record can provide such information but is sometimes unreliable as it may be, of necessity, based upon unreliable data; the species of the birds involved may not …

The German Military Geophysical Service. Bird Migration Observation, Warning And Forecasting System: New Developments Towards An Automated Bird Migration Information System, Wilhelm Ruhe

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The German Military Geophysical Office (GMGO) has a more than 30-years experience in all fields of bird strike prevention. Military training and flight operations usually take place in low altitudes, where also a lot of birds are present, especially near coasts and during migration periods. About one third of all the GAF bird strikes occurs during low level flight operations. The most effective tool for bird strike prevention in military low level flying is the well proved system of
· continuous actual bird migration observation (visual and by radar),
· immediate reporting,
· centralised risk evaluation,
· online warning (BIRDTAM), …

Integrated Management Systems For Australian White Ibis (Threskiornis Molucca) On The Gold Coast, Queensland, Australia, Phillip P. Shaw

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Fueled by a large supplemental food supply at landfills in South-east Queensland, Australian White Ibis (Threskiornis molucca) populations grew from an estimated 5000 to 10000 between 1995 and 1998. Ibis counted at Coolangatta Airport reflected this growth with a 556% increase between 1989 and 1995. The multimillion-dollar loss of a Qantas airbus engine from ingestion of an Ibis, resulted in the establishment of the Ibis Management Coordination Group (IMCG). This group, comprising government, industry and community representatives, instigated an integrated program of food reduction, restriction of breeding success and public education. The program has become an example for management programs …

The Use Of Night Landfilling To Reduce Bird Hazards To Aircraft Safety, Rolph A. Davis, Joseph Mangino

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The Atlantic County Utilities Authority (ACUA) operates a ‘bulky waste’ (non-putrescible waste) landfill at a site that is 10,300 ft from the end of the main runway at the Atlantic City (NJ) International Airport (ACY). The airport supports the Federal Aviation Administration’s Technical Center. The ACUA also operates a transfer station at its site. Municipal solid waste (msw = putrescible) is delivered to the transfer station during the day. Previously, the msw was loaded onto transfer trucks and shipped to an out-of-state landfill. In October 1997, the ACUA received a permit to conduct a 2-year experiment to dispose of the …

Bird Strike Risk Analysis On Aktion Airfield (Greece) And Recommendations For Improvements In Bird Strike Prevention, Heinrich Weitz

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

A survey of Aktion airfield in Greece was carried out from 14 to 18 October 1996 initiated by the Flight Safety Division of the NATO E-3A Component Geilenkirchen (Germany) as an reaction to the accident of an AWACS-aircraft on 14. July 1996, initially caused by a bird strike event. The survey of Aktion airfield led to the conclusion that the bird strike risk is extremely high at this airfield. Reasons are:
· The geographical location of the airfield at the Adriatic coast which is a migratory pathway for many birds.
· The location of the airfield on a narrow peninsula …

Temporal And Spatial Patterns Of Avifauna On Wetlands In The Vicinity Of Bush Field Airport, Augusta, Georgia, Usa, Robert A. Kennamer, L. Brisbin Jr., K. F. Gaines, W. L. Stephens Jr.

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Responding to a U.S. Federal court order to improve discharged wastewater quality, Augusta, Georgia initiated development of artificial wetlands in 1997 to treat effluents. Because of the proximity to Augusta Regional Airport at Bush Field, the U.S. Federal Aviation Administration expressed concern for potential increased hazard to aircraft posed by birds attracted to these wetlands. We commenced weekly low-level aerial surveys of habitats in the area beginning January, 1998. Over a one-year period, 49 surveys identified approximately 42,000 birds representing 52 species, including protected Wood Storks and Bald Eagles, using wetlands within 8 km of the airport. More birds were …

Close-Range And Satellite Remote Sensing Of Algal Biomass In The Iowa Great Lakes, Eric A. Wilson

Department of Geography: Dissertations, Theses, and Student Research

The utility of both close-range and satellite remote sensing for assessing inland water quality was examined in the Iowa Great Lakes. The water quality of this system is of considerable interest because of its status as an environmental, recreational, and therefore, economic resource. The broad range of optical conditions present in the lakes and the wealth of literature on the system make it an ideal environment for water quality remote sensing research. The goal of this research was to survey the water quality of the Iowa Great Lakes via remote sensing, evaluate different predictive algorithms, and map the distribution of …

An Assessment Of The World-Wide Risk To Aircraft From Large Flocking Birds, J. R. Allan, J. C. Bell, V. S. Jackson

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The difficulties encountered in interpreting the available data, which arise from incomplete or inaccurate information being submitted, or from inconsistent reporting by national organisations, illustrate the importance of recording and reporting birdstrike incidents. Even allowing for the fact that birdstrikes with large birds, and especially those with flocks, are more likely to be reported, it is probable that the database established for this project contains only a fraction of the incidents that have actually occurred. Nevertheless, some broad conclusions can be drawn from the data available, and as more data are collected, predictions and estimates can be refined and the …

The Effects Of Changes In The Northern Lapwing Population On The Bird Strike Hazard In The Uk, J. C. Bell

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Changes in bird populations have been recognised as affecting the risk to aircraft of a bird strike. However, in terms of bird strike prevention, changes are generally only considered at the local level i.e. reducing the number of birds on the airfield. At a national level, concern has been expressed about recent increases in waterfowl, particularly geese, and the implications that this may have for flight safety, and management of the risk. However, although work is currently being undertaken to investigate if higher numbers of large waterfowl are causing an increased risk to safety (Allan, Bell & Jackson in press), …

Feather Identification And A New Electronic System For Reporting Us Air Force Bird Strikes, Carla J. Dove

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The number of bird strike cases received from U.S. Air Force bases for identification has increased from 640 in 1996 to more than 840 in 1998. The additional workload, together with staff shortages on the BASH team, created a need for a more efficient reporting system. Previously, all bird strike remains were funneled through the Safety Center at Kirtland Air Force Base where they were logged into a database, forwarded to the Smithsonian Institution for identification, and then sent back to Kirtland for data entry of results before being returned to field personnel. This system facilitated a bottleneck in the …

Derivation Of A Dummy Bird For Analysis And Test Of Airframe Structures, Chris H. Edge, J. Degrieck

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Certification of aircraft against the birdstrike threat is expensive and time consuming. With the need to reduce design life cycle time and costs with ever more complex structures (materials, geometries and manufacturing methods) yet with no reduction in safety, the possibilities of certification via generic analysis is an attractive proposition. This paper discusses one approach being considered within British Aerospace (BAe). It relies heavily on research activities that have derived extensive data for bird biometrics and innovative testing that can provide mechanical data for bird failure modes unique to military aircraft.

Whilst almost all birdstrike clearance is performed via testing …

Multicenter Comparison Of Pcr Assays For Detection Of Human Herpesvirus 8 Dna In Semen, Philip E. Pellett, Thomas J. Spira, Omar Bagasra, Chris Boshoff, Lawrence Corey, Laura De Lellis, Meei-Li Huang, Jung-Chung Lin, Steve Matthews, Paolo Monini, Paola Romessi, Carlos Sosa, Charles Wood, John A. Stewart

Nebraska Center for Virology: Faculty Publications

Reported prevalences of human herpesvirus 8 (HHV-8) (Kaposi’s sarcoma-associated herpesvirus) in semen have ranged widely. This is possibly due to differences in assay sensitivity, geographic or population-based differences in the true presence of the virus in semen, and PCR contamination. This study assessed interlaboratory sensitivity and reproducibility in the analysis of blinded experimental panels, each consisting of 48 specimens and being composed of semen specimens from different healthy artificial-insemination donors (n = 30) and human immunodeficiency virus (HIV)-infected patients (n= 7) plus positive (n = 4) and negative (n = 7) controls. The experimental panels analyzed in each laboratory were …

Analysis Of Intraguild Predation With A Consideration Of Adaptive Foraging, Toshinori Okuyama

School of Biological Sciences: Dissertations, Theses, and Student Research

Identification of interactive units in food webs is particularly important in population and community ecology. Intraguild predation has gained much attention recently with the recognition of its prevalence in the field, although its significance has not been fully studied. Nature contains much more complex interactions than a simple food chain. Yet, much theory still focuses on the trophic levels connected in a single linear chain. In this thesis, I study intraguild predation including the consideration of animal behavior whose importance is also often neglected in population and community ecology.

First, the concepts of intraguild predation and animal behavior are introduced. …

Mutational Analysis Of The Role Of Hpr In Listeria Monocytogenes, Douglas P. Christensen, Andrew K. Benson, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

The regulatory role of HPr, a protein of the phosphotransferase system (PTS), was investigated in Listeria monocytogenes. By constructing mutations in the conserved histidine 15 and serine 46 residues of HPr, we were able to examine how HPr regulates PTS activity. The results indicated that histidine 15 was phosphorylated in a phosphoenolpyruvate (PEP)-dependent manner and was essential for PTS activity. Serine 46 was phosphorylated in an ATP-dependent manner by a membrane-associated kinase. ATP-dependent phosphorylation of serine 46 was significantly enhanced in the presence of fructose 1,6-diphosphate and resulted in a reduction of PTS activity. The presence of a charge …

Ecologically Sound Biological Control For Invasive Species?: Review Of Pedro Barbosa, Ed., Conservation Biological Control, Svata M. Louda

School of Biological Sciences: Faculty Publications

The timeliness of Conservation biological control, edited by Pedro Barbosa, is striking. Invasive exotic species often represent an economic cost for agriculture and sometimes an environmental threat to the integrity of native vegetation in national forests, parks, and reserves. Problems caused by the most obvious noxious species are bringing more public awareness of invasives. As a consequence, on 3 February 1999, President Clinton issued an executive order to coordinate and stimulate research and management of invasive exotic species. ... The suggested alternative approach to biological-based management of invasive species is exciting in its ecological justification and its sustainability. Environmental …

Pyoveridine Production By Pseudomonas Aeruginosa Exposed To Metals Or An Oxidative Stress Agent, Kim-Hien Thi Dao, Katherine E. Hamer, Christine L. Clark, Lawrence G. Harshman

School of Biological Sciences: Faculty Publications

Siderophores are low molecular mass compounds used by many microorganisms to scavenge dissolved iron, which is typically rare in environments. Pseudomonas aeruginosa (PAO1) was exposed to metals and methyl viologen in low-iron medium in order to monitor the abundance of a specific siderophore (pyoverdine) and monitor growth over time. In this study it was discovered that cadmium can stimulate pyoverdine abundance. Cadmium may interact with and sequester the Fur regulatory protein, which represses siderophore synthesis under conditions of iron sufficiency. Mercury did not stimulate pyoverdine production at concentrations that strongly inhibited bacterial growth, suggesting that pyoverdine production is not governed …

Genetic Consequences Of Mammalian Social Structure, Jay F. Storz

Jay F. Storz Publications

Populations of social mammals are characterized by several demographic features that may increase the magnitude of genetic drift relative to other evolutionary forces. In particular, polygynous mating and socially mediated constraints on gene flow have been proposed to foster random genetic differentiation among social groups, thereby accelerating rates of evolutionary change. To evaluate this hypothesized link between sociality and genetic sub- division, I examined results of published studies of mammalian populations in which genetic structuring was assessed at the level of social groups. Population genetic data from a taxonomically diverse array of social mammals revealed low to moderately high levels …

Growth Of Nanotubes For Probe Microscopy Tips, Jason H. Hafner, Chin Li Cheung, Charles M. Lieber

Barry Chin Li Cheung Publications

Carbon nanotubes, which have intrinsically small diameters and high aspect ratios and which buckle reversibly, make potentially ideal structures for use as tips in scanning probe microscopies, such as atomic force microscopy (AFM)^{1, 2, 3, 4}. However, the present method of mechanically attaching nanotube bundles for tip fabrication is time consuming and selects against the smallest nanotubes, limiting the quality of tips. We have developed a technique for growing individual carbon nanotube probe tips directly, with control over the orientation, by chemical vapor deposition (CVD) from the ends of silicon tips. Tips grown in this way may become …

A New Subspecies Of Brephidium Isophthalma (Lycaenidae: Polyommatinae) From Coastal South Carolina, Harry Pavulaan, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Brephidium isophthalma pseudofea was described in 1873 from the Florida Keys, United States. The ventral ground color of the wings in topotypical pseudofea is a yellowish brown. The antennal clubs of pseudofea have prominent orange red tips. The ventral surface of the abdomen of pseudofea is broadly white to very light gray and usually extends halfway around the sides of the light to medium brown abdomen. Specimens of B. isophthalma from coastal South Carolina differ greatly from topotypical pseudofea. Accordingly, B. i. insularus is described as a new subspecies from coastal South Carolina. The antennal clubs …
