Predicting Flock Vigilance From Simple Passerine Interactions: Modelling With Cellular Automata, David B. Bahr, Marc Bekoff

Ethology Collection

Vigilance in flocks can be described and modelled as a plausible set of local interactions between neighbouring birds. Each bird in the modelled flock chooses to feed or to scan based solely on whether or not its neighbours are feeding or scanning. This simple model has the ability both to reproduce observations that have not been previously explained and to predict flock behaviours that might be confirmed with future field studies. Examples include simulations showing decreased vigilance with increased flock size (as observed in the field), greater time spent scanning when obstacles such as trees are present (as observed) and …

The Southern Resident Orcinus Orca Population In Puget Sound: Hypotheses On Population Ratios And The Effects Of The Capture Era On Behavior Of The Whales, Beth Phillips

WWU Honors College Senior Projects

This project set out to assess the population status of the southern resident community of Orcinus orca, the killer whale, in Puget Sound. The current number of whales in the community is 84, down from 97 in 1995, and it has been hypothesized that their numbers will continue to decline in the future. The study focused specifically on the residual effects of the capture era in the 1960’s and 1970’s that systematically cropped immature male and female killer whales from the southern resident community. Then, the behavioral adaptations that the killer whales appear to be making in response to …

Gender Variation In Croton Californicus (Euphorbiaceae), James Lynwood Smith Ii

Loma Linda University Electronic Theses, Dissertations & Projects

Croton californicus Muell. Arg. (Euphorbiaceae) is a subshrub suspected of being dimorphic with phase choices. Gender variation in C. californicus was studied in natural populations of southern California for three years (1994-96) to observe patterns of gender !ability. Some sites exhibited significantly male-biased sex ratios, and these sites often had the greatest number of monoecious morphs, cosexual plants with unisexual flowers. Gender variation was quantified for cosexual plants by calculating the Estimated Floral Gender (EFG) which varied from 1.00 (female) to 0.00 (male). The distribution of the EFG was highly skewed towards maleness. Monoecious individuals were then categorized by …

Maternal Employment And Dietary Quality Of Children Aged 42-60 Months, Lynn A. Samson

Masters Theses

(From the Summary): Abbreviated Maternal employment is becoming more the usual than an exception. Employment can be beneficial for mothers, providing satisfaction and increasing self-esteem. On the other hand, it can be stressful juggling between the roles of employee and mother. Other family members might help ease some of the burden, but mothers still bear most of the responsibility of child care and household responsibilities. Working mothers have less time to spend on food and nutrition. In most cases, the diets of children whose mothers are employed do not differ from children of mothers who are not employed, …

Use Of Extractable Lipofuscin For Age Determination Of Blue Crab Callinectes Sapidus, Se-Jong Ju, David H. Secor, H. Rodger Harvey

OES Faculty Publications

The blue crab Callinectes sapidus is an economically and ecologically important species in many temperate estuaries, yet stock assessments have been limited to length-based methods for demographic analyses. We evaluated the potential of age pigments (lipofuscins) sequestered in neural tissue of eye-stalks and brains to estimate the age of blue crabs collected from Chesapeake Bay and Chincoteague Bay. The rate of lipofuscin accumulation was determined using crabs of known age reared in the laboratory. Age pigments were extracted from neural tissues (eye-stalk or brain), quantified, and normalized to protein content to allow comparisons across tissue types and crab sizes. Field-collected …

Universal Design And Nature Trails: Balancing Accessibility, Site Integrity, And The Recreation Experience, Steve Kirkindall

Electronic Theses and Dissertations

This study addressed the application of Americans With Disabilities Act (ADA) guidelines in outdoor recreation settings. The purpose was three-fold: to develop site- and user-friendly design principles for non-urban, accessible nature trails; to design and construct a trail based on those principles; and to evaluate both principles and trail by surveying trail users. The Delphi Method was employed with a national panel to assess current expert opinion regarding accessibility and trails. Fifty-nine principles were developed from combined results of panel deliberations and applied experience gained constructing a prototype trail utilizing the universal design concept. Trail users rated the importance of …

A Genetic Analysis Of The Relationship Between Life-History Variation And Heat-Shock Tolerance In Drosophila Buzzatii, Robert A. Krebs, Volker Loeschcke

Biological, Geological, and Environmental Faculty Publications

Although exposure to environmental stress is common in most populations, and the physiological effects of stress on individuals are well studied, the evolutionary importance of stress to populations is not well understood. To address multitrait responses to environmental change and potential constraints on character evolution, we analysed, in 100 isofemale lines of Drosophila buzzatii, the genetic relationships between resistance to a short heat shock and several life-history traits: survival in benign conditions, larval developmental time, fecundity and longevity. Estimates of heritability of larval thermotolerance were low, but significant, and all life-history traits varied significantly among isofemale lines. Several of …

Engineering Secreted Proteins For Gene Transfer And Dna Vaccination, Jingxue Liu

Loma Linda University Electronic Theses, Dissertations & Projects

In recent years gene therapy has become a promising way of alleviating incurable human ailments, its concept emerging as the ultimate therapy for many infectious and genetic diseases. Two important aspects of the development of successful gene therapy protocols are the ability to monitor gene transfer readily, and the establishment of new protocols for treating specific diseases. In this work, Renilla luciferase and human glutamic acid decarboxylase (GAD) 65 were engineered for secretion to address some aspects of these issues.

Secreted reporter proteins are promising tools to study gene transfer and expression in a non-destructive manner, and bioluminescent proteins are …

Maternal Modulation Of Neonatal Immunity, Omar R. Fagoaga

Loma Linda University Electronic Theses, Dissertations & Projects

Although the neonatal immune system is functionally immature, immune response capabilities are not the same in all newborns. The objective of this thesis was to determine development of immunocompetence and test the hypothesis that activation of maternal inflammatory immunity during pregnancy influences maturation of the neonatal immune system.

Lymphocytes in blood and spleen were immunophenotyped by flow cytometric analysis to determine differentiation characteristics, and splenocytes were assessed for cytokine production capabilities. In normal Th2-prone outbred (CD-1) mice, an adult repertoire of naïve lymphocytes has developed by day 10 and memory cells by day 20, in blood and spleen. However, in …

An Evaluation Of Gastrointestinal Parasites In The Mixed Breed/Pure Breed Pound Dog Population Of East Baton Rouge Parish, Stalanda L. Bradford

Electronic Dissertations and Theses

ABSTRACT An evaluation of gastrointestinal parasites was performed on mixed breed and pure breed pound dogs of East Baton Rouge Parish. Fecal samples were analyzed by the Modified Sheather's Sugar Floatation Technique. Of the 54 canine specimens, 55.6% were female and 44.4% were males. Overall, 19 of the 54 (35.19%) canines were infected. The male canines had the higher infectious condition of the two genders, and the crossbred canines had the higher infectious condition of the two breeds. Also, hookworms were the most prevalent gastrointestinal parasites found within this population.

Ecology Of The Malay Civet (Viverra Tangalunga) In A Logged And An Unlogged Forest In Sabah, East Malaysia, Christina P. Colon

Publications and Research

Malay civets in a dipterocarp rain forest were studied from December, 1995, through June, 1997, in the Ulu Segama Forest Reserve in Sabah, East Malaysia. To investigate the basic ecology of this species and explore the potential impact of selective logging, data on home range, activity and diet were collected on study animals in an unlogged and a selectively logged forest, and comparisons made.

Density in the unlogged forest was 1/0.46 km² , and 1/1.07 km² in the logged forest. Mean home range size based on a 95% minimum convex polygon was 110 ha. and did not differ …

The Reproductive Biology And Edaphic Characteristics Of A Rare, Gynodioecious Saxifage: Saxifraga Bryophora Var. Tobiasiae (Saxifragaceae), Kimberly Pierson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I examined the reproductive biology and general ecology of Saxifraga bryophora var. tobiasiae, a rare saxifrage endemic to the West Salmon River Mountains of central Idaho. Saxifraga bryophora var. tobiasiae combines asexual reproduction via bulbils with a sexual mixed-mating system. Flower production occurred in 1996 only, whereas bulbil production occurred in 1995, 1996, and 1997. Bulbil production precedes floral bud formation and is the dominant form of reproduction. When flowering occurs, outcrossing is promoted by protandry and the gynodioecious mating system found in all populations. No autogamous or agamospermous seed set was observed in either female or hermaphrodite flowers, …

A Survey Of The General Public Assessing Public Attitudes Toward Animal Damage Control Management Policy, Douglas K. Reiter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A mail survey of randomly selected stratified U.S. households assessed general attitudes toward wildlife and specific concerns about wildlife damage management and the federal Animal Damage Control program. Respondents strongly supported federal government's role in ensuring public safety, engaging in public education, and continuing research into nonlethal control methods. Weaker support was found for lethal control of predators and crop depredators, and financial compensation for losses due to wildlife activities was generally opposed. Lethal methods of control were generally considered to be inhumane and nonlethal methods humane. When asked to rank the importance of factors to be considered when selecting …
