Velocity, Force, Power, And Ca2+ Sensitivity Of Fast And Slow Monkey Skeletal Muscle Fibers, Robert Fitts, Sue C. Bodine, Janell Romatowski, Jeffrey J. Widrick

Biological Sciences Faculty Research and Publications

In this study, we determined the contractile properties of single chemically skinned fibers prepared from the medial gastrocnemius (MG) and soleus (Sol) muscles of adult male rhesus monkeys and assessed the effects of the spaceflight living facility known as the experiment support primate facility (ESOP). Muscle biopsies were obtained 4 wk before and immediately after an 18-day ESOP sit, and fiber type was determined by immunohistochemical techniques. The MG slow type I fiber was significantly smaller than the MG type II, Sol type I, and Sol type II fibers. The ESOP sit caused a significant reduction in the diameter of …

The Effects Of Tactile/Kinesthetic Instructional Strategies In The Biology Classroom, Janice Batten Sees

Theses and Dissertations

The purpose of this study was to determine whether the addition of tactile/kinesthetic instruction to the biology classroom could significantly increase learning. Various kinds of tactile/kinesthetic lessons were taught to three experimental groups who also received visual and auditory instruction. These tactile/kinesthetic lessons included task cards, task puzzles, manipulatives, total body movement, and large floor games. The control group only received visual and auditory instruction. The subjects were 84 College Biology students from Buena Regional High School, a school in rural South Jersey. The classes varied in gender and race. The same instructor taught all classes and the length of …

Mechanism Of Triazolo-Benzodiazepine And Benzodiazepine Action In Anxiety And Depression: Behavioral Studies With Concomitant In Vivo Ca1 Hippocampal Norepinephrine And Serotonin Release Detection In The Behaving Animal, Patricia A. Broderick, Omotola Hope, Pierrot Jeannot

Publications and Research

1. Real time, in vivo microvoltammetric studies were performed, using miniature carbon-based sensors, to concurrently detect norepinephrine (NE) release and serotonin (5-HT) release, in 2 separate electrochemical signals, within CA₁ region of hippocampus in the freely moving and behaving, male, Sprague Dawley laboratory rat.

2. Concurrently, four parameters of open-field Behavior I.E. Ambulations, Rearing, Fine Movements and Central Ambulatory behavior (a measure of anxiety reduction behavior), were assayed by infrared photobeam detection.

3. Time course studies showed that the mechanism of action of the triazolobenzodiazepine (TBZD), adinazolam, (Deracyn®) is dramatically different from that of the classical benzodiazepine (BZD), diazepam …

Grandmothering, Menopause, And The Evolution Of Human Life Histories, K. Hawkes, J.F. O'Connell, N.G. Blurton Jones, H. Alvarez, Eric Charnov

Biology Faculty & Staff Publications

Long postmenopausal lifespans distinguish humans from all other primates. This pattern may have evolved with mother—child food sharing, a practice that allowed aging females to enhance their daughters fertility, thereby increasing selection against senescence. Combined with Charnov's dimensionless assembly rules for mammalian life histories, this hypothesis also accounts for our late maturity, small size at weaning, and high fertility. It has implications for past human habitat choice and social organization and for ideas about the importance of extended learning and paternal provisioning in human evolution.

The Influence Of Habitat Variation On Demography Of Blue Jays (Cyanociita Cristata) In South-Central Florida, Keith Allen Tarvin

USF Tampa Graduate Theses and Dissertations

Vertebrate populations rarely are homogeneous. Instead they exist as arrays of demographically variable subpopulations that are linked through dispersal. Variation in habitat quality is a major cause of demographic variability among subpopulations, but few studies have examined habitat-specific demography empirically. Here I present a detailed field study o f habitat-specific demography in Blue Jays (Cyanocitta cristata) that occupied a habitat mosaic landscape in south-central Florida. By measuring habitat-specific demographic parameters, including density, reproductive output, survival, and dispersal, I tested for the existence of population sources and sinks associated with different habitats, and the applicability ofa series ofhabitat selection models …

Managing The Iatrogenic Risks Of Risk Management, Jonathan Baert Wiener

RISK: Health, Safety & Environment (1990-2002)

Analogizing to concerns that led the practice of medicine to shift from a specialist to a team-based approach, Dr. Wiener suggests that public and environmental health objectives would be better served if, e.g., regulatory jurisdiction were less atomized.

Hef481 Maintaining A Treasure Chest: Your Health Record (Participant Manual), Jodene K. Jurging, Mary Ellen Rider, Rebecca L. Versch, Judy Weber

University of Nebraska-Lincoln Extension: Historical Materials

The health care system in the United States is changing in ways that require consumers to take more responsibility for their health. The preventive philosophy of health care demands that we move from passive recipients to active consumers of health care. A very important part of health care is maintaining accurate medical records for yourself and members of your family.

You may say, "My physician keeps that record." Have you ever seen a copy of that file? Do you have just one health care provider responsible for your care? Does your medical provider pay your bills? How private is your …

Self-Organization Of Foraging Behaviour: From Simplicity To Complexity Without Goals, Frederick D. Provenza, Juan J. Villalba, Carl D. Cheney, Scott J. Werner

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

A herbivore faces challenges while foraging--ongoing changes in its physiological condition along with variation in the nutrient and toxin concentrations of foods, spatially and temporally--that make selecting a nutritious diet a vital affair. Foraging behaviours arise from simple rules that operate across levels of resolution from cells and organs to individuals and their interactions with social and physical environments. At all these levels, behaviour is a function of its consequences: a behaviour operating on the environment to induce changes is itself changed by those events. Thus, behaviour emerges from its own functioningbehaviour self-organizes-not from that of its surroundings. This ostensible …

The Foraging Ecology Of The Gray Rat Snake (Elaphe Obsoleta Spiloides)-Visual Stimuli Facilitate Location Of Arboreal Prey, Robert J. Cooper, Stephen J. Mullin

Faculty Publications

We examined the responsiveness of adult gray rat snakes to avian prey in enclosures that simulated natural habitat conditions. Subjects searched for arboreal nest contents in the presence or absence of a bird model flown so as to simulate avian provisioning behavior. In the absence of the model, gray rat snake latency to capture prey was over 92 % greater than when searching for nest contents with the model. Snakes responded to model flight by turning their heads in the direction of its movement. We conclude that gray rat snakes perceive relatively distant visual cues from prey, and that nest …

Psychology's Use Of Animals: Current Practices And Attitudes, Kenneth J. Shapiro

Experimentation Collection

In this chapter, I present a psychology primer for the uninitiated, with special emphasis on psychology's uses of animals. After sketching the scope of the field generally, I review available data on present numbers and species of animals used in psychological research, level of suffering induced and current trends. I also provide several concrete examples of psychological research involving animals. Finally, the chapter concludes with a presentation of attitudes of psychologists toward animals and these practices.

‘Pleasures’, ‘Pains’ And Animal Welfare: Toward A Natural History Of Affect, D. Fraser, I. J.H. Duncan

Animal Welfare Collection

In hedonic theories of motivation, 'motivational affective states' (MASs) are typically seen as adaptations which motivate certain types of behaviour, especially in situations where a flexible or learned response is more adaptive than a rigid or reflexive one. MASs can be negative (eg unpleasant feelings of hunger or pain) or positive (eg pleasant feelings associated with eating and playing). Hedonic theories often portray negative and positive MASs as opposite ends of a one-dimensional scale.

We suggest that natural selection has favoured negative and positive affect as separate processes to solve two different types of motivational problems. We propose that negative …

Translocation Effects On The Behavior Of Black-Tailed Prairie Dogs (Cynomys Ludovicianus), John P. Farrar, Karin L. Coleman, Marc Bekoff, Eric Stone

Ethology Collection

We examined the effects of translocation on Black-tailed prairie dog (Cynomys ludovicianus) anti-predator behavior by recording response distances and response times to a human intruder in three colonies containing native, translocated, and combined native and translocated prairie dogs. The translocated prairie dogs barked alarms and concealed themselves at significantly greater intruder distances than mixed or native colonies. However, individuals in different colonies did not differ in the time taken to return to a burrow, to conceal themselves after a human approached the colony, or in the time elapsed after concealment until an animal reappeared. Translocated prairie dogs exhibited nearly twice …

Landscape Management Challenges On The California Channel Islands, William L. Halvorson

Aliso: A Journal of Systematic and Floristic Botany

Managing for sustained biodiversity and restoration of natural habitat has become increasingly important over the last two decades, first as mitigation for development (especially in wetlands), and , more recently in natural areas. The latter has come about as land managing agencies like the Department of Defense and Bureau of Land Management have seen the need to reverse the impact of past land uses and agencies like the National Park Service and The Nature Conservancy have taken on the responsibility for less-than-pristine lands.

On the California Channel Islands, the need for restoring and managing biodiversity is great, but this restoration …

G98-1365 Don't Let Stress Get You Down!, Herbert G. Lingren, Ladeane Jha, Judith A. Schwab, Barbara L. Schmidt, Connie Francis, Jeanette Friesen, Janet S. Hanna

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide defines stress and its relationship to anger. It discusses a stress management model, stress-busting technique and helps the reader develop a stress management plan.

What is Stress?

Stress has become a catch-all term to describe events or circumstances that make us feel tense or angry. Stress often is caused by events over which we have no control (destruction of home by tornado or sudden death of a family member) or by a positive event (birth of child). However, most stress comes from the daily pile-up of small aggravations and frustrations.

It is not "things" or events themselves, however, …
