The Ecology And Evolution Of Spatial Memory In Corvids Of The Southwestern Usa: The Perplexing Pinyon Jay, Russell P. Balda, Alan Kamil
The Ecology And Evolution Of Spatial Memory In Corvids Of The Southwestern Usa: The Perplexing Pinyon Jay, Russell P. Balda, Alan Kamil
Papers in Behavior in Biological Sciences
The corvids of the southwest possess many adaptations for the harvest, transport, caching and recovery of pine seeds. However, there is a large degree of between-species variation in the distribution of these traits. These corvids have a well-accepted phylogeny (Hope, 1989), live within close proximity to one another and have relatively well-known natural histories. They therefore present an excellent opportunity to apply the comparative method (Kamil, 1988) to the study of these species differences (Balda et al., 1997). The comparative method for the study of adaptation and evolution of behavioral traits begins with a careful study of the natural histories …
On The Proper Definition Of Cognitive Ethology, Alan Kamil
On The Proper Definition Of Cognitive Ethology, Alan Kamil
Papers in Behavior in Biological Sciences
The last 20-30 years have seen two “scientific revolutions” in the study of animal behavior: the cognitive revolution that originated in psychology, and the Darwinian, behavioral ecology revolution that originated in biology. Among psychologists, the cognitive revolution has had enormous impact. Similarly, among biologists, the Darwinian revolution has had enormous impact. The major theme of this chapter is that these two scientific research programs need to be combined into a single approach, simultaneously cognitive and Darwinian, and that this single approach is most appropriately called cognitive ethology.
Evaluation Of The Role Of Fructosamine As An Indicator Of Diabetic Control, Katherine Hooley
Evaluation Of The Role Of Fructosamine As An Indicator Of Diabetic Control, Katherine Hooley
Theses
Diabetes mellitus, a common metabolic disease, is characterised by excess circulating glucose concentrations. Such a hyperglycaemic status provides the stimulus for irreversible glycation (non-enzymatically post-translational) of structural and functional proteins. Protein glycation, although a cause of complication (neuropathy, micro/macrovascular disease), provides a time-averaged index of diabetes status and control. In particular, glycated plasma proteins analysis, i.e., the fructosamine assay, has received favourable response due to its speed, simplicity, low cost, and ease of automation. However, lack of standardisation and a universally-accepted calibrant has limited technical and subsequent clinical confidence in fructosamine analysis. In response, a comprehensive technical evaluation (including novel …

G98-1345 Family Asset Mapping, Herbert G. Lingren
University of Nebraska-Lincoln Extension: Historical Materials
All families have assets. Strengthening them is critical for a healthy family life. This NebGuide presents several opportunities for doing that.
The Family Relationship Bank Account
Successful family living requires two bank accounts: a financial account, which allows the purchase of goods and services, and a relationship account, which promotes sustainability, bonding and togetherness. When assets are many and the account balance is large, there is enough "money" to meet the relational demands that exist between couples, the family demands of raising children and the social demands of living in a community. At other times, when withdrawals are high, or …

The Effects Of Habitual Physical Activity On Number Of Colds And Incidence Of Cold Symptoms, Katie Lynn Maniatis
The Effects Of Habitual Physical Activity On Number Of Colds And Incidence Of Cold Symptoms, Katie Lynn Maniatis
Masters Theses
The purpose of this investigation was to compare frequency of colds and symptoms of upper respiratory infection in college students who have different levels of habitual physical activity. Subjects were Eastern Illinois University students (N=535, aged 18-25). A survey was conducted which included questions inquiring about demographic information, physical activity habits, the number of colds contracted the month before the survey, and symptom number and severity. Data collection occurred between February 12th and March 1st, 1998. This particular time period was chosen for several reasons, including that student stress level should have been lower than at the beginning or end …

Identification Of Speeded And Slowed Familiar Melodies By Younger, Middle-Aged, And Older Musicians And Nonmusicians, Melinda W. Andrews, W. Jay Dowling, James C. Bartlett, Andrea R. Halpern
Faculty Journal Articles
There is a range of tempos within which listeners can identify familiar tunes (around 0.8 to 6.0 notes/s). Faster and slower tunes are difficult to identify. The authors assessed fast and slow melody-identification thresholds for 80 listeners ages 17–79 years with expertise varying from musically untrained to professional. On fast-to-slow (FS) trials the tune started at a very fast tempo and slowed until the listener identified it. Slow-to-fast (SF) trials started slow and accelerated. Tunes either retained their natural rhythms or were stylized isochronous versions. Increased expertise led to better performance for both FS and SF thresholds (r = .45). …
Evaluating Stress In Calves Weaned At Three Different Ages, Andrea Bueno, Todd Cappel, Chuck Story, Richard J. Rasby, Edd Clemens, Mark Dragastin
Evaluating Stress In Calves Weaned At Three Different Ages, Andrea Bueno, Todd Cappel, Chuck Story, Richard J. Rasby, Edd Clemens, Mark Dragastin
Nebraska Beef Cattle Reports
Trials were conducted to evaluate the effects of weaning calves at 150, 210 and 270 days of age (i.e. August, October and December, respectively). A total of 75 Angus x MARC II heifers calves were used in this study. Heifers were bled on the day of weaning and again at 2, 7, 14 and 28 days after weaning. Blood was analyzed for differential WBC, cortisol, T3 and glucose. Weight changes were recorded. The data suggests October weaned calves (210 days) had both greater blood cortisol and glucose at days 7, 14 and 28 post-weaning and greater weight gains when …

Olfactory Responses Of Glossina Fuscipes Fuscipes (Diptera: Glossinidae) To The Monitor Lizard Varanus Niloticus Niloticus, M. M. Mohamed-Ahmed
Olfactory Responses Of Glossina Fuscipes Fuscipes (Diptera: Glossinidae) To The Monitor Lizard Varanus Niloticus Niloticus, M. M. Mohamed-Ahmed
All Peer-Reviewed Publications
Visual and olfactory responses of Glossina fuscipes fuscipes Newstead to the monitor lizard, Varanus niloticus niloticus Laurenti were studied using various catching devices near Lake Victoria, Kenya. Electric nets baited with visible lizards caught more males (x2.1) and significantly more females (x2.0) than unbaited nets. Lizards concealed in electrified black Pvc pipe models, simulating the shape and size of a monitor lizard, increased significantly the catches of tsetse by 2.1 times. Fresh lizard urine dispensed at an evaporation rate of 500 to 1000 mg/h also increased significantly the catches of flies at biconical traps, electrified models and electric nets. Identification …

Preface: Animal Cognition In Nature, Russell P. Balda, Irene M. Pepperberg, Alan Kamil
Papers in Behavior in Biological Sciences
This volume, Animal Cognition in Nature, is the result of an ongoing synthesis of several ideas that were considered revolutionary, if not heretical, in the 1960s. At that time, animal behavior, whether studied in field or laboratory, by ethologists or psychologists, was generally interpreted as the result of simple processes relating specific stimuli to specific behaviors. Examples from that time include S–R models, sign stimuli, IRMs, etc. Theoretical constructs such as mental representations, memory or attention were avoided. Today, students of animal behavior work in an entirely different atmosphere. This is the result of several developments.
One of these developments …
The Effect Of Background Cuing On Prey Detection, Henry Kono, Pamela J. Reid, Alan Kamil
The Effect Of Background Cuing On Prey Detection, Henry Kono, Pamela J. Reid, Alan Kamil
Papers in Behavior in Biological Sciences
Studies of prey detection have typically focused on how search image affects the capture of cryptic items. This study also considers how background vegetation influences cryptic prey detection. Blue jays, Cyanocitta cristata, searched digitized images for two Catocala moths: C. ilia, which is cryptic on oak, and C. relicta, which is cryptic on birch. Some images contained moths while others did not. The ability of blue jays to detect prey during repeated presentations of one prey type within a session was compared with their performance during randomly alternating presentations of both prey types within a session to …

The Effects Of A Goal Setting Intervention And Dispositional Optimism/Pessimism On Selected Golf Skills: A Qualitative Design, Matthew James Wilson
The Effects Of A Goal Setting Intervention And Dispositional Optimism/Pessimism On Selected Golf Skills: A Qualitative Design, Matthew James Wilson
College of Graduate Studies: Theses & Dissertations (1964–2006)
The purpose of this study was to examine the effects of a goal setting intervention on selected golf skills over the course of a competitive golf season. A secondary purpose of this study was to investigate a comparison of optimism and pessimism in relationship to goal attainment. Subjects (n=7) were elite golfers from a university men's golf team. A two-month goal setting intervention was implemented consisting of the individual golfers selecting three golf skills from five separate categories (fairways in regulation, greens in regulation, total putts per round, up and downs conversion rate, and putts per green in regulation) to …
The Effects Of Aerobics And Walking On Social Physique Anxiety And Self-Esteem Of Female College Students, Jessica L. Lloyd
The Effects Of Aerobics And Walking On Social Physique Anxiety And Self-Esteem Of Female College Students, Jessica L. Lloyd
College of Graduate Studies: Theses & Dissertations (1964–2006)
The purpose of this investigation was to explore the effectiveness of walking and aerobics as a way of modifying body image apprehension and self-esteem of female college students. Participants from this study comprised 88 (25 African Americans and 63 Caucasians) students from a Southeastern university. The participants were administered the 9-item Social Physique Anxiety Scale (SPAS) (Martin, Rejeski, Leary, McAuley, & Bane, 1997) and the Rosenberg Self-Esteem Scale (RSES) (Rosenberg, 1979). Body composition, body weight, body height, and body mass index (BMI) were also evaluated. The participants performed in a 9-week walking or aerobics physical activity class. At the completion …

Categorical And Coordinate Spatial Judgements In Face Recognition, Jill E. Russell
Categorical And Coordinate Spatial Judgements In Face Recognition, Jill E. Russell
Theses : Honours
The role of the cerebral hemispheres in processing spatial relationships is outlined in Kosslyn 's (1987) theory that states that there are two separate subsystems for processing spatial relations: one located in the left hemisphere (LHem) that is more efficient at processing categorical information, and one in the right hemisphere (RHem) that is more efficient at processing coordinate information. To test Kosslyn's theory, this study manipulated two IVs in a within-subjects design, task: categorical and coordinate; and visual field (VF): left and right Male and female face stimuli were presented in either the left visual field (LVF) to the (RHem) …
Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman
Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman
Theses : Honours
Investigations into the mediators of effort sensation have indicated that central mechanisms related to corollary discharges may be responsible for an increased sense of effort during fatiguing isometric exercise. The role for central mediators for sense of effort have been objectively demonstrated through use of contralateral limb matching tasks. Subjects diagnosed with chronic fatigue syndrome (CFS) often report prevalent fatigue associated with a greater sense of effort when involved in exercise. This study employed a fatiguing contralateral limb-matching task in order to determine if CFS subjects (n == 6) experienced an altered sense of effort associated with the task when …

Dealing With Death And The Grieving Process, David M. Gabel
Presidential Scholars Theses (1990 – 2006)
There are two things that our society doesn't really openly discuss. Oddly enough, they are things that will affect everyone on this planet regardless of race, religion, gender, class, or nationality. I am speaking of the beginning of life, and the end of life. The subject of how life begins is for some reason "taboo" in our society. Children are told absurd things like children are brought to their parents by birds, such as a stork. Another popular tale is that children are "grown" in gardens and are discovered under leaves. The subject of sex seems to be one that …

The Magnitude Of Site And Time Interaction Effect In Tsetse Fly (Diptera: Glossinidae) Trap Catches, A. Odulaja, S. Mihok, I. M. Abu-Zinid
All Peer-Reviewed Publications
Site and time effects are important factors determining trap catches of tsetse flies. These factors may interact significantly and therefore confound interpretation of time series data used for population monitoring. We therefore investigated the magnitude and importance of site x time interactions in trap catches of Glossina pallidipes Austen and G. longipennis Corti using a 2200 trap-days (400 trap-months) data set. The interaction was found to be significant (P < 0.05) in 46-100% of the combinations of different numbers of months and sites between 2 and 12. The mean percent variance due to the interaction ranged between 4% and 28% for G. pallidipes and 12% and 36% for G. longipennis. The interaction was usually less important than the effect of site alone but more important than the effect of time alone. These results suggest that tsetse researchers should examine critically the adequacy of existing approaches to population monitoring with traps and to testing new traps and odour baits.

Farrowing Behaviour And Stillbirth In Two Environments: An Evaluation Of The Restraint-Stillbirth Hypothesis, D. Fraser, P. A. Phillips, B. K. Thompson
Reproductive Behavior Collection
A total of 59 farrowings were studied in either a conventional, narrow farrowing crate (0.43 m wide) or a much wider alternative design with sides spaced 1.2 m apart at the sow’s standing height but narrowing near the floor to limit the sow’s lying area. Using video recording, we monitored each “birth interval” (i.e. the period between two successive births) and noted the interval’s length, the sow’s posture and postural changes during the interval, and whether the interval ended with a live-born or stillborn piglet. The wide and conventional crates did not differ significantly in median interval between piglets (15.9 …
Postnatal Observations Of Behavioral Patterns Within The Social Organization Of Captive Bottlenose Dolphins (Tursiops Truncatus), Stacey R. Hanson
Postnatal Observations Of Behavioral Patterns Within The Social Organization Of Captive Bottlenose Dolphins (Tursiops Truncatus), Stacey R. Hanson
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Mirage Dolphin Environment opened in 1991. The Mirage has eight Atlantic Bottlenose dolphins. Four of these dolphins were relocated to the facility from other facilities that were either overcrowded or shutting down. The other four were born at the Mirage. The purpose and intent of the Mirage Dolphin Environment is to provide a nurturing environment for the dolphins and to educate the public about marine mammals and their ecosystems. The increased awareness associated with education will hopefully encourage public support for efforts to conserve and protect marine mammals and their environment.
Weapon Size Versus Body Size As A Predictor Of Winning In Fights Between Shore Crabs, Carcinus Maenas (L.), Lynne U. Sneddon, Felicity A. Huntingford, Alan C. Taylor
Weapon Size Versus Body Size As A Predictor Of Winning In Fights Between Shore Crabs, Carcinus Maenas (L.), Lynne U. Sneddon, Felicity A. Huntingford, Alan C. Taylor
Veterinary Science and Medicine Collection
Relative body size (carapace width) and weapon size (chela length) were used as indicators of resource holding potential (RHP) in the agonistic behaviour of male shore crabs, Carcinus maenas (L.). Weapon size was found to be a more reliable predictor of the outcome of pairwise fights than body size. Crabs with longer chelae than their opponents were more likely to win fights than crabs with relatively larger bodies. Body size had less influence on the outcome of fights. Relative body and weapon size did not influence initiation of contests but did affect the likelihood of winning; however, this was significant …
