Water Conditioning And Whooping Crane Survival After Release In Florida, George F. Gee, Jane M. Nicolich, Stephen A. Nesbitt, Jeff S. Hatfield, David H. Ellis, Glenn H. Olsen

Proceedings of the North American Crane Workshop

About 50% of the whooping cranes (Grus americana) released in Florida die within the first year of release. Most of these deaths and those in subsequent years result from bobcat (Lynx rufus) predation. Choosing release sites in open marshes away from bobcat habitat has improved survival. We hypothesized that exposure to ponds (water conditioning) at the rearing site would encourage birds to roost in deeper water marshes after release and such exposure would thereby reduce bobcat predation. In this study, we moved young birds (ca 50 days of age) to netted pens with large (I5-m diameter), deep (30--60 …

Mortality Of Whooping Crane Colts In Wood Buffalo National Park, Canada, 1997–99, Douglas G. Bergeson, Brian W. Johns, Geoffrey L. Holroyd

Proceedings of the North American Crane Workshop

Twenty-two whooping crane (Grus americana) pairs with 2 young were monitored in Wood Buffalo National Park (WBNP) over 3 years to determine causes of colt mortality. The family groups were monitored from the ground, air, and with the aid ofradioteiemetry. We attached transmitters to 18 colts: 5 (28%) fledged, 5 (28%) succumbed to cumulative effects (head trauma, stress, exposure and/or infection), 4 (22%) were lost to unknown causes (3 of these went missing after they had lost their transmitters), 2 (11%) were taken by foxes (Vulpes vulpes), 1 (5.5%) was lost to raven (Corvus corax …

Egg Collection And Recruitment Of Young Of The Year In The Aransas/Wood Buffalo Population Of Whooping Cranes, John R. Cannon, Brian W. Johns, Thomas V. Stehn

Proceedings of the North American Crane Workshop

We present data for 61 years (1938 to 1998) on the recruitment of juvenile (i.e., young-of-the-year) whooping cranes (Grus americana) for the 1 natural wild population that nests in the vicinity of Wood Buffalo National Park (WBNP) in Canada and migrates annually to wintering grounds in the vicinity of Aransas National Wildlife Refuge (ANWR) on the Gulf coast of Texas in the United States. We divide these years into 2 data sets: years during which 1 of 2 eggs was collected from WBNP nests (to develop captive populations and to conduct reintroduction experiments), and years during which no …

Status Of Sandhill Cranes In Indiana, John S. Castrale, James Bergens

Proceedings of the North American Crane Workshop

Historically, the sandhill crane (Grus canadensis) was considered a common migrant throughout Indiana and a locally abundant breeding bird in northwestern Indiana until 1929. Most of the Eastern Population of greater sandhill cranes (G. c. tabida) is thought to congregate each fall at Jasper-Pulaski Fish and Wildlife Area before migrating to Florida and Georgia. Systematic weekly fall counts began in 1967 and annual peak numbers have increased from 2,500 in 1967 to 27,600 in 1997, with a record count of 32,600 in 1991. Fall migrants are noticeable by late September, peak in mid-October through mid-November, and …

Tracking Sandhill Crane Migration From Saskatchewan To The Gulf Coast, Dale G. Hjertaas, David H. Ellis, Brian W. Johns, Stacie L. Moon

Proceedings of the North American Crane Workshop

Four adult sandhill cranes (Grus canadensis rowani) were captured in east-central Saskatchewan, equipped with transmitters, and tracked by satellite to detennine if their migration routes and wintering areas would allow their use as guide birds to establish a new migratory flock of whooping cranes (G. americana). Two birds captured near Yorkton died or their transmitters were lost before migration. Two adults from the Overflowing River moved to staging areas in southern Saskatchewan in September. By 29 September, Crane A left Saskatchewan and moved to North Dakota where it remained until late October. By 21 December, it …

Manipulating Dna Conformation Using Intertwined Conducting Polymer Chains, Ramaswamy Nagarajan, Wei Liu, Jayant Kumar, Sukant K. Tripathy, Ferdinando F. Bruno, Lynne A. Samuelson

United States Army: Publications

In the field of inherently conducting polymers, polyaniline (Pani) has elicited tremendous interest due to its promising electrical properties and unique redox tunability. Synthetic routes involving the use of polyelectrolytes have significantly improved the processability of polyaniline. Recently, a template guided synthesis catalyzed by an enzyme, horseradish peroxidase (HRP), has provided a means of polymerizing aniline under milder pH conditions (pH 4.3) and subsequently widened the choice of templates to more delicate biological macromolecules. Here we report a strategy that exploits the inherent molecular order as well as the polyelectrolyte behavior of DNA to enzymatically synthesize and biologically assemble conducting …

Lab Fattening And Non-Invasive Estimates Of Body Composition In Deer Mice, Edward T. Unangst, Michael J. Blair, Matthew W. Granger, David W. Hale

United States Air Force: Publications

Total body electrical conductivity measurements and lipid composition were determined for the deer mouse (Peromyscus maniculatus) to derive species specific calibration equations for use with EM-SCAN estimates of lean and fat tissue. For each individual, total body electrical conductivity was measured by EM-SCAN, and actual lipid content was determined by chemical extraction. Then, using estimated and actual lipid values, separate calibration equations were generated for freshly captured (lean) and laboratory maintained (fat) individuals, and a combined equation was derived for all individuals. These equations were variable in the accuracy of lipid estimates; the lowest relative error estimate (percent …

Effect Of Extraction Buffer On Estimating Calpain And Calpastatin Activity In Postmortem Ovine Muscle, E. Veiseth, M. Koohmaraie

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

The effect of extraction buffer on extractable calpain and calpastatin activity in postmortem muscles was examined. Muscles were removed from ovine carcasses 24 h after slaughter and extracted with three volumes of two extraction buffers containing 20 (pH 7.5) and 100 (pH 8.3) mM Tris. There was a significant difference in pH of the muscle homogenates, having a pH of 5.84 and 7.58 for 20 and 100 mM Tris base, respectively. Calpastatin, μ-calpain and m-calpain all had signifcantly reduced activity in extracts made with 20 mM Tris (pH 7.5) buffer compared to 100 mM Tris (pH 8.3) buffer, showing a …

A Porcine Bac Library With Tenfold Genome Coverage: A Resource For Physical And Genetic Map Integration, Scott C. Fahrenkrug, Gary A. Rohrer, Brad A. Freking, Timothy P. L. Smith, Kazutoyo Oswoegawa, Chung Li Shu, Joseph J. Catanese, Pieter J. De Jong

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

Recent advances in porcine genomics have identified quantitative trait loci (QTL) that influence pork production traits such as carcass traits, meat quality, and reproductive efficiency (Rohrer 2000; Cassady 1999). The low resolution to which most of these loci have been defined precludes the accurate application of markerassisted selection (MAS) strategies for increasing production efficiency. Large-insert genomic libraries are an excellent resource for marker development aimed at increasing the resolution of QTL and for the development of contiguous physical maps (contigs) of the chromosomal regions containing them.

Disordered Eating And Its Psychosocial Correlates Among Hispanic Adolescent Females, Annette Santiago

All-Inclusive List of Electronic Theses and Dissertations

This study investigated the incidence of disordered eating and its relationship with acculturation, depression, and body dissatisfaction among Hispanic adolescent females. One hundred and five students enrolled at two midwestern high schools completed a Student Demographic Questionnaire, the Bidimensional Acculturation Scale for Hispanics (Marin & Gamba, 1996), the Beck Depression Inventory (Beck, Steer, & Brown, 1996), the Body Dissatisfaction Subscale of the Eating Disorder Inventory (Garner, Olmstead, & Polivy, 1983), and the Eating Attitudes Test (Garner, Olmstead, Bohr, & Garfinkel, 1982). Two null hypotheses were examined. The first investigated the relationship among acculturation, depression, body dissatisfaction, and disordered eating utilizing …

Differential Diagnosis Of Orofacial Pain I: Associated With Intracranial And Extracranial Structures And Psychogenic Disorders, Rodolfo Acosta-Ortiz

HPD Articles

Orofacial Pain (OFP) is a common problem among the general population and represents a condition that is potentially debilitating and deteriorating. The correct diagnosis is the principal base for an adequate management; in patients with DOF this may be a simple task or a very complex and frustrating experience for both, clinician, and patient. However, the clinician's knowledge of all possible pain condition that can affect the orofacial region can facilitate the diagnostic process. It is important to emphasize that is very difficult to diagnose something unknown for the clinician and even though "common things occur commonly", it is not …

Evolution Of Mammal Life Histories, Eric Charnov

Biology Faculty & Staff Publications

If we assume that adult life span and age-at-maturity are described correctly by quarter power allometries across (typical) mammal species, we are tempted to look for some fundamental explanation. The explanation must acknowledge that within-species growth is sigmoid and not a power function at all, and that natural selection probably sets the age at maturity in the face of externally imposed mortality, while also allowing some mortality adjustment due to internal factors. This paper develops hypotheses to account for the above scaling rules and it predicts the numeric values of several new dimensionless numbers that interrelate growth, mortality and investment …

Disturbed Landscape/Disturbing Processes: Environmental History For The Twenty-First Century, Vera Norwood

American Studies Faculty and Staff Publications

On the first weekend of May 2000, the opening act of the nation's most impressive environmental drama of the summer was staged in Los Alamos, New Mexico. News releases covered a massive forest fire, named the Cerro Grande, exploding through forest stands, consuming over 40,000 acres of homes, recreation areas, and wildlands, burning perilously close to nuclear facilities, and threatening religious sites of Santa Clara pueblo. The fire, generated from a Park Service prescribed burn set in Bandolier National Monument and feeding on heavy fuel loads in the Santa Fe National Forest, raged out of control for days. Los Alamos …

G01-1434 Controlling Beaver Damage, Dallas R. Virchow, John M. Hobbs, Ronald Fryda, Scott E. Hygnstrom

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes beaver biology and behavior and characterizes the types of damage caused by them. It suggests control methods and equipment and describes legal restrictions.

The beaver (Castor canadensis) is the largest rodent in North America. Adults weigh about 40 pounds and have been known to weigh up to 60 pounds or more. Beavers are admired for being industrious, curious, and social. Historically, both the American beaver and the European beaver (Castor fiber) were overharvested to near extinction. In recent decades, however, both species have been rapidly increasing.

Arbovirus Infection Increases With Group Size, Charles R. Brown, Nicholas Komar, Sunita B. Quick, Rajni A. Sethi, Nicholas A. Panella, Mary Bromberger Brown, Martin Pfeffer

Zoonotics and Wildlife Disease: Publications

Buggy Creek (BCR) virus is an arthropod-borne alphavirus that is naturally transmitted to its vertebrate host the cliff swallow (Petrochelidon pyrrhonota) by an invertebrate vector, namely the cimicid swallow bug (Oeciacus vicarius). We examined how the prevalence of the virus varied with the group size of both its vector and host. The study was conducted in southwestern Nebraska where cliff swallows breed in colonies ranging from one to 3700 nests and the bug populations at a site vary directly with the cliff swallow colony size. The percentage of cliff swallow nests containing bugs infected with BCR …

Biotransformation Of Ni-Substituted Hydrous Ferric Oxide By An Fe(Iii)-Reducing Bacterium, James K. Fredrickson, John M. Zachara, Ravi K. Kukkadapu, Yuri A. Gorby, Steven C. Smith, Christopher F. Brown

United States Department of Energy: Publications

The reductive biotransformation of a Ni²⁺-substituted (5 mol %) hydrous ferric oxide (NiHFO) by Shewanella putrefaciens, strain CN32, was investigated under anoxic conditions at circumneutral pH. Our objectives were to define the influence of Ni²⁺ substitution on the bioreducibility of the HFO and the biomineralization products formed and to identify biogeochemical factors controlling the phase distribution of Ni²⁺ during bioreduction. Incubations with CN32 and NiHFO were sampled after 14 and 32 d, and both aqueous chemistry and solid phases were characterized. By comparison of these results with a previous study (Fredrickson, J. K.; Zachara, J. M.; …

Dissimilatory Bacterial Reduction Of Al-Substituted Goethite In Subsurface Sediments, Ravi K. Kukkadapu, John M. Zachara, Steven C. Smith, James K. Fredrickson, Chongxuan Liu

United States Department of Energy: Publications

The microbiologic reduction of a 0.2 to 2.0 µm size fraction of an Atlantic coastal plain sediment (Eatontown) was investigated using a dissimilatory Fe(III)-reducing bacterium (Shewanella putrefaciens, strain CN32) to evaluate mineralogic controls on the rate and extent of Fe(III) reduction and the resulting distribution of biogenic Fe(II). Mössbauer spectroscopy and X-ray diffraction (XRD) were used to show that the sedimentary Fe (III) oxide was Al-substituted goethite (13–17% Al) that existed as 1- to 5-µm aggregates of indistinct morphology. Bioreduction experiments were performed in two buffers [HCO₃^‑; 1,4-piperazinediethansulfonic acid (PIPES)] both without and with 2,6-anthraquinone …

Kinetics And Mechanism Of Birnessite Reduction By Catechol, Christopher J. Matocha, Donald L. Sparks, James E. Amonette, Ravi K. Kukkadapu

United States Department of Energy: Publications

The complex interactions of oxidizable organic ligands with soil Mn(III,IV) (hydr)oxide minerals have received little study by in situspectroscopic techniques.We used a combination of an in situ electron paramagnetic resonance stopped-flow (EPR-SF) spectroscopic technique and stirred-batch studies to measure the reductive dissolution kinetics of birnessite (δ-MnO₂), a common Mn mineral in soils, by catechol (1,2-dihydroxybenzene). The reaction was rapid, independent of pH, and essentially complete within seconds under conditions of excess catechol at pH 4 to 6. The overall empirical second-order rate equation describing the reductive dissolution rate was d[Mn(II)]/dt = k[CAT]^1.0[SA]^1.0 where …

Kinetic Analysis Of The Bacterial Reduction Of Goethite, Chongxuan Liu, John M. Zachara, James K. Fredrickson, Cynthia Brinkman

United States Department of Energy: Publications

The kinetics of dissimilatory reduction of goethite (RFeOOH) was studied in batch cultures of a groundwater bacterium, Shewanella putrefaciens, strain CN32 in pH 7 bicarbonate buffer. The rate and extent of goethite reduction were measured as a function of electron acceptor (goethite) and donor (lactate) concentrations. Increasing goethite concentrations increased both the rate and extent of Fe(III) reduction when cell and lactate concentrations were held constant. However, constant initial reduction rates were observed after normalization to the Fe(II) sorption capacity of FeOOH, suggesting that the bacterial reduction rate was first order with respect to surface site concentration. Increasing …

Uncertainties Of Monod Kinetic Parameters Nonlinearly Estimated From Batch Experiments, Chongxuan Liu, John M. Zachara

United States Department of Energy: Publications

Monod kinetic parameters (K_s, µmax, and Y) that are estimated from batch experimental data can have large uncertainties due to linear correlations between them. The degree of correlation and the resulting uncertainties of the Monod parameters are functions of the initial experimental conditions, the values of the parameters, the type and magnitude of measurement errors, and the sampling number. Careful manipulation of experimental conditions can reduce the correlations between Monod parameters allowing for the estimation of Monod kinetic parameters with the lowest degree of uncertainty. By dimensionless analysis, the correlation and relative standard deviations of Monod parameters …
