Thermoregulation And Sleep: Effects Of Thermal Stress On Sleep Patterns Of Glaucous-Winged Gulls (Larus Glaucescens), Mark Opp, Nigel Ball, Don Miller, Charles Amlaner

Charles J. Amlaner

1. To determine effects of thermal stress on avian sleep patterns, incubating Glaucous-winged gulls were subjected to conditions of heat loss and heat gain via conduction from hollow copper eggs.

2. Heated manipulations resulted in significant reductions in sleep and rest relative to controls, whereas cooled manipulations had little effect.

3. The resilience of sleep to thermal stress is greater than that of rest. We suggest that the incompatability of sleep with conductive processes to off-load heat from the eggs is responsible in this case.

4. Pant Sleep, the behaviour in which birds appear to maintain some the benefits of ...


Lake Mead Cover Enhancement Project, Jennifer Stevens Haley, Suzanne Leavitt, Larry Paulson, Donald H. Baepler Jul 1987

Lake Mead Cover Enhancement Project, Jennifer Stevens Haley, Suzanne Leavitt, Larry Paulson, Donald H. Baepler

Publications (WR)

Ninety-three wildlife agencies were surveyed for information on their attempts to improve fish habitat. In addition, an annotated bibliography including over 100 summaries was completed on:

1. largemouth bass cover requirements and preferences,

2. use and effectiveness of artificial cover,

3. aquatic plant introduction and species requirements for germination and establishment,

4. terrestrial plant introduction and species requirements for germination and establishment, and

5. nutrient exchange between sediment, aquatic plants, and water.

A reconnaissance of existing terrestrial and aquatic vegetation was completed in June 1986 including the production of a video tape of the Nevada shoreline of Lake Mead.

Genetic Control Of Immune Response To Pseudorabies And Atrophic Rhinitis Vaccines: I. Heterosis, General Combining Ability And Relationship To Growth And Backfat, David Lynn Meeker, Max F. Rothschild, L. L. Christian, C. M. Warner, H. T. Hill Jan 1987

Genetic Control Of Immune Response To Pseudorabies And Atrophic Rhinitis Vaccines: I. Heterosis, General Combining Ability And Relationship To Growth And Backfat, David Lynn Meeker, Max F. Rothschild, L. L. Christian, C. M. Warner, H. T. Hill

Animal Science Publications

Data from 988 pigs from 119 litters farrowed in two seasons of a three-breed diallel crossbreeding experiment were analyzed to estimate general combining abilities of breeds and heterosis for humoral immune response to pseudorabies virus and atrophic rhinitis vaccines. Twenty purebred boars and 85 sows of the Duroc, Landrace and Yorkshire breeds were mated to provide the nine breed-of-sire and breed-of-dam combinations. Immune response was measured after vaccination. A modified-live pseudorabies virus (PR) vaccine was administered to piglets at 28 d of age and response measured as log2 serum neutralization titers at 56 d. An inactivated B. bronchiseptica bacterin ...


Genetic Control Of Immune Responsiveness: A Review Of Its Use As A Tool For Selection For Disease Resistance, C. M. Warner, David Lynn Meeker, Max F. Rothschild Jan 1987

Genetic Control Of Immune Responsiveness: A Review Of Its Use As A Tool For Selection For Disease Resistance, C. M. Warner, David Lynn Meeker, Max F. Rothschild

Animal Science Publications

Disease resistance and immune responsiveness have been traits generally ignored by animal breeders. Recent advances in immunology and molecular biology have opened new avenues towards our understanding of genetic control of these traits. The major histocompatibility gene complex (MHC) appears to play a central role in all immune functions and disease resistance. The need to understand the relationship between immune responsiveness, disease resistance and production traits is discussed in this review. Antagonistic relationships might prevent simultaneous improvement of all of these traits by conventional breeding methods. It is suggested that genetic engineering methods may allow the simultaneous improvement of disease ...


Genetic Control Of Immune Response To Pseudorabies And Atrophic Rhinitis Vaccines: Ii: Comparison Of Additive Direct And Maternal Genetic Effects, David Lynn Meeker, Max F. Rothschild, L. L. Christian, C. M. Warner, H. T. Hill Jan 1987

Genetic Control Of Immune Response To Pseudorabies And Atrophic Rhinitis Vaccines: Ii: Comparison Of Additive Direct And Maternal Genetic Effects, David Lynn Meeker, Max F. Rothschild, L. L. Christian, C. M. Warner, H. T. Hill

Animal Science Publications

Data from 52 litters farrowed in two seasons of a cross-fostering experiment were analyzed to estimate variances and covariances for additive direct and maternal genetic effects on immune response to pseudorabies virus and B. bronchiseptica vaccine. Twenty purebred boars and 44 sows of the Duroc, Landrace and Yorkshire breeds were used. Immune response was measured after vaccine challenge. A modified-live pseudorabies (PR) vaccine was administered to piglets at 28 d of age; response was measured by log, serum neutralization titers at 56 d. An inactivated B. bronchiseptica bacterin was administered at 28, 42 and 112 d. Antibody levels were measured ...


A Novel Insulin From The Bullfrog: Its Structure And Function In Protein Secretion By Hepatocytes , Jocelyn Jean Hulsebus Jan 1987

A Novel Insulin From The Bullfrog: Its Structure And Function In Protein Secretion By Hepatocytes , Jocelyn Jean Hulsebus

Retrospective Theses and Dissertations

Bullfrog insulin was extracted and purified from the pancreas of Rana catesbeiana adults using gel filtration and reverse phase high performance liquid chromatography. Amino acid analysis of bullfrog insulin revealed 52 amino acids instead of the most common number of 51. Hagfish insulin is the only other known insulin with 52 amino acids. The most unique feature of bullfrog insulin is a two amino acid extension on the amino terminus (A1) of the A chain. This is the only insulin to date that has an extension at this position. In mammals, the deletion of A1 glycine or addition of a ...
