An Ecosystem-Based Approach To Management: Using Individual Behaviour To Predict The Indirect Effects Of Antarctic Krill Fisheries On Penguin Foraging, Suzanne Alonzo, Paul Switzer, Marc Mangel

Faculty Research & Creative Activity

Summary 1. Changes in species' abundance and distributions caused by human disturbances can have indirect effects on other species in a community. Although ecosystem approaches to management are becoming increasingly prevalent, they require a fuller understand- ing of how individual behaviour determines interactions within and between species. 2. Ecological interactions involving krill are of major importance to many species within the Antarctic. Despite extensive knowledge of the ecosystem that they occupy, there is still incomplete understanding of the links between species and the effect of environmental conditions on these interactions. In this study, we extended a behavioural model used previously …

Effects Of Experience And Body Size On Refuge Choice In The Crayfish Orconectes Immunis, Patrick Forsythe, Deborah Wyatt, Paul Switzer

Faculty Research & Creative Activity

We investigated whether refuge size or experience with a refuge affected the refuge use of male Orconectes immunis crayfish. Individuals were given choices among seven refuges for 10 consecutive days. Refuges were formed from equal length but different diameter PVC pipe and placed in an array in a random sequence. Three treatments were used. In the Novel Refuge treatment, individuals were placed in a new test arena with a new arrangement of cleaned refuges every day. In the Nonremoval treatment, individuals were left in the same arena with the same set of refuges each day. In the Removal treatment, individuals …

Investigation Of Matrilineal Relationships Via Mitochondrial Dna In The Southeastern Yellowjacket (Vespula Squamosa), Anthony Deets

Masters Theses

The question of whether and how apparently "altruistic" behaviors can evolve in social animals has received an enormous amount of attention from evolutionary biologists and has been termed "the central theoretical problem of sociobiology". Thus, recent interest is eusocial species with coexisting multiple queens stems from the realization that the genetic relatedness of individuals in such colonies presents additional theoretical challenges beyond those addressed by the Hamiltonian model of kin selection and lengthens the potential list of reproductive conflicts of interest.

The Southeastern Yellowjacket (Vespula squamosa) exhibits two social forms sympatrically in the southern parts of its range. These two …

Nest-Site Selection In The Eastern Box Turtle, Terrapene Carolina Carolina, In A Population In Central Illinois, Beth Flitz

Masters Theses

Nest site selection in turtles might allow females to increase the survival of their offspring but little is known about the variables that influence that choice. I examined the microhabitat variables at nest sites of the eastern box turtle, Terrapene carolina carolina, at a Boy Scout camp in Shelby County, Illinois, to determine if females chose nest sites that differed from random sites within the camp. Nest sites differed from random sites in vegetation height and composition, percentage ground and canopy cover, and light intensity. All females placed their nests in open habitat within the camp or a pasture bordering …

Synthesis And Characterization Of A Polypyridyl Ru(Ii)-Alloxazine Complex For Adsorption On Tio2-Coated Ito Electrodes, Manisha A. Patel

Masters Theses

TiO₂-coated conducting glass electrodes can be modified by attachment of redox-active molecules to the TiO₂ surface. This thesis describes the synthesis and characterization of a polypyridyl Ru(II) complex that can be covalently bound to a TiO₂ surface through the carboxylate groups of 2,2'-bipyridine-4,4' -dicarboxylic acid, H₂dcbpy. In addition, the bound complex contains a redox-active alloxazine derivative, pptd, which is capable of 2e^-/2H⁺ transfers. Thus the TiO₂-coated electrode is modified with a transition metal complex capable of shuttling H-atoms to substrates in solution. Synthesis of the PF₆^- salt …

Cell Biology Of Apoe In Cortical Cultured Neurons: Possible Roles In Alzheimer's Disease, Anna G. Barsukova

Masters Theses

The apolipoprotein E4 (apoE4) genotype is a major risk factor for Alzheimer's disease (AD). Previous studies have shown that apoE4 is less effective than apoE3 in supporting neurite outgrowth in adult mice cortical cultures. However the mechanism underlying this phenomenon is not known. To understand this mechanism and the broader role of apoE isoforms on neuronal biology I examined the rate of apoE isoforms internalization in neurons, effects of apoE isoforms on lipid uptake by neurons, effects of apoE isoforms on neuronal environment - microglia and on neuroregeneration, or neurogenesis.

I examined the binding and internalization of recombinant human apoE3 …

Middle School Student Attitudes Towards Robotics, Science And Technology, J. Jill Rogers

Masters Theses

In 2000, the National Science Foundation (NSF) conducted a biennial study on the status of women and minorities in science and engineering. It was revealed that the numbers of women receiving bachelor's degrees in computer science are on the decline. This fact calls for innovative changes in the traditional science curriculum. Science instruction with the implementation of robotics could provide female students the needed motivation. Therefore, the examination of female middle school student attitudes towards robotic enhanced science instruction is needed. Descriptive research was conducted to assess middle school student attitudes towards robots, technology and science. Gender differences were studied. …

Anthropogenic-Induced Changes To Weather And Climate: An Overview, Robert Cataneo

Masters Theses

Human activities, since the beginning of the Industrial Revolution, have caused measurable and significant changes to local and regional weather and climate, as well as to global climate.

There is substantial evidence to show that anthropogenic influences have caused statistically significant changes to local and regional weather and climate, and have played a major role in the 0.6°C increase in global, low level temperature observed in the last 100 years. There is also an abundance of data that establishes a causal relationship between the 32% increase in atmospheric CO₂ concentration that has occurred since the beginning of the Industrial …

Motherlands Of The Mind: A Study Of The Women Characters Of Attia Hosain's Sunlight On A Broken Column And Salman Rushdie's Midnight's Children, Umme Sadat Nazmun Nahar Al-Wazedi

Masters Theses

In my thesis I examine the portrayal of women characters by two post-colonial Indian writers, Attia Hosain and Salman Rushdie, respectively in Sunlight on a Broken Column (1961) and Midnight's Children (1980). I show how Hosain's and Rushdie's ideas of identity, nation and nationality influence their depiction of these women characters.

In the section analyzing Sunlight on a Broken Column, I argue that there is a spatial veil separating the feudal world of "Ashiana" from the outside world with its political disturbances, the life of a woman as an individual from the life of a woman as a part …

Dmap As A Catalyst For Carbon Acylation: Elucidation Of Mechanistic Pathway, Including Spectral Characterization Of The Putative Reactive Intermediate, Jagadish K. Boppisetti

Masters Theses

3-Phenylbenzofuranone, when deprotonated with sodium hydride, forms an extended enolate system which, when treated with excess alkyl chloroformates, affords only oxygen-acylated products, as opposed to the usually desired carbon-functionalized derivatives. It was discovered that such molecules, when treated with a catalytic amount of 4- (N, N-dimethylamino)pyridine (DMAP), rearrange quantitatively to the carbon acylated isomers.

These migrations, which are accompanied by a deep blue color, are proposed to involve a reactive intermediate. This intermediate, which is postulated as an ion pair charge transfer (IPCT) complex, has been closely studied in order to gain a better understanding of the …

Factors Influencing Substance Abuse/Dependence And Treatment Outcome Of Adolescents In A Residential Substance Abuse Program: An Exploratory Study, Melissa L. Moody

Masters Theses

Previous research examining the risk factors associated with alcohol and other drug use has primarily focused on the adult population. Few studies have investigated the factors which influence adolescent substance abuse and the respective effects on treatment outcome. This in spite of the considerable decline in the age-of-onset for problematic substance use that could, if gone untreated, escalate into dependence and a variety of other interpersonal problems which extend across the lifespan. Effective interventions targeting the adolescent population would therefore seem to be of utmost importance to both researchers and clinicians. It has been suggested that individualized treatment programs focusing …

Regional Dispersal Of Daphnia Lumholtzi In North America Inferred From Issr Genetic Markers, G. Matthew Groves

Masters Theses

The exotic zooplankter Daphnia lumholtzi is believed to have been introduced into Fairfield Lake, TX in 1983. Since introduction, D. lumholtzi has spread throughout the Midwest and Southeast United States. Due to its large head and tail spines, it may be less susceptible than native species to predation and therefore pose a threat to aquatic ecosystems. Development of management practices calls for study of the dispersal and potential impact of D. lumholtzi on invaded ecosystems.

Inter-simple sequence repeat (ISSR) markers were used in an effort to determine dispersal patterns of D. lumholtzi. Previous studies have shown that ISSRs possess …

The Mermaid's Dress: Marriage And Empire In The Voyage Out And Mrs Dalloway, Melissa Wharton-Smith

Masters Theses

This thesis examines how socio-historical influences shape the protagonists of Virginia Woolf’s The Voyage Out (1915) and Mrs. Dalloway (1925)-- Rachel Vinrace and Clarissa Dalloway. During the writing of these two novels, attitudes about roles for women before and after World War I shifted as pre-war domestic strife was replaced by a post-war push to return to normalcy. Throughout the period, imperialist ideology demanded that women conform to traditional gender roles by marrying and reproducing. Woolf depicts this pressure as it affects her two protagonists.

In The Voyage Out, the British Empire's imposing presence is exhibited through the setting of …

Behavioral Aspects Of Apolipoprotein E Knockout Mice, Melissa T. Litherland

Masters Theses

Apolipoprotein E (apoE) is a lipid transporting protein that has been shown to play a vital role in nerve repair and remodeling. Previous studies have shown that apoE is highly expressed in human and mouse olfactory bulbs. ApoE deficiency in apolipoprotein E knockout (apoE-KO) mice leads to considerable delay in olfactory nerve repair and deficits in olfactory functioning. Olfactory function is necessary for a number of social behaviors in mice. Loss of olfaction can greatly reduce social behaviors. Since apoE-KO mice display olfactory dysfunction, this deficit may result in alterations in social behavior. Olfactory function was assessed in apoE-KO mice …

Teachers' Perceptions Of Attention Deficit Hyperactivity Disorder: Incidence And Management, Julie M. Olson

Masters Theses

ADHD continues to be a common diagnosis of school children, and according to the DSM-IV, it affects approximately 3-5% of the population. Teachers are often the primary source of information regarding ADHD diagnoses in school children. A previous study by Glass and Wegar (2000) found that teachers were over-identifying children with ADHD and that medication was preferred as the primary treatment for these students. This study further examines teacher perceptions on the causes, incidence, and appropriate treatment methods of ADHD. In addition, this study also examines the prevalence of ADHD as determined by the ADHD Rating Scale-IV (School Version) (DuPaul …

Coastal Habitat Use By Wood Storks During The Non-Breeding Season, A. L. Bryan Jr., Karen F. Gaines, C. S. Eldridge

Faculty Research & Creative Activity

We documented roosting and foraging habitat use by Wood Storks during the post-breeding season in the coastal zone of Georgia from 1994-1998. Larger, more persistent aggregations of roosting storks typically oc- curred in enclosed wetlands on large estuarine islands. Smaller, more ephemeral aggregations tended to occur on salt marsh/upland ecotones, where storks appeared to be waiting for local conditions (tide levels) to become suit- able for foraging. Examination of habitat types within a 2-km radius of the larger (mean > 10 storks/survey) vs. smaller (mean <10 storks/survey) roosts showed that surrounding habitat structure, including those used for for- aging, were similar. Foraging storks typically fed in close proximity (median = 0.5 km) to large roosts, much closer than storks using coastal wetlands during the breeding season. Tidal creeks were used almost exclusively as foraging habitat (92%). Storks and other wading birds were almost always present when the study bird arrived. The foraging patterns of study birds and four storks carrying radios suggested that storks often used the same foraging sites and/ or marsh systems in the non-breeding season. Coastal Wood Storks apparently selected roosting sites based on the presence of conspecifics, abundant local prey, or possibly as shelter from adverse weather conditions
